SECTION I - CLASS DEFINITION
This is a residual class for metal fusion bonding as defined
in this definition.
For placement of a patent in this class, its claimed disclosure
should meet the minimum requirements of the class definition, and
should not extend beyond the boundaries indicated in Scope of the
Class, below, and discussed in Lines With Other Classes and Within
This Class.
Terms followed by an asterisk (*) in the definitions
are defined in the Glossary, below.
This class provides for an apparatus for or a method of joining
the meeting faces of juxtaposed or engaged metal work parts or of
the same part originally in a form-sustaining state, by the direct
application of heat and/or mechanical energy to either
of: (a) such work parts, to such an extent as to effect a flowing
or blending together of some of the metal in neighboring regions
of said work parts into a continuous metallic zone interconnecting
said work parts, or (b) such work parts and a metallic filler, to
such an extent as to effect a flowing or blending together of the
filler and some of the metal of said work portions into a continuous
metallic zone interconnecting said work portions with filler and
thus with each other.
Additionally, this class provides for methods of joining a
metal work part to a juxtaposed or engaged nonmetal work part wherein
bonding there between is effected by intermingling of the molecules
of the metal part with the nonmetal part; and for methods of joining
juxtaposed or engaged nonmetal work parts when utilizing metallic cement.
SCOPE OF THE CLASS
Placement of an original patent into Class 228 may be made
on the basis of a claim reciting means for or the step of applying
to work portions energy in the form of: (1) heat; (2) pressure;
and/or (3) vibratory energy, provided that there is a teaching
that a metal fusion bonded product is produced by the applied energy.
Also see Class 420, Alloys or Metallic Compositions.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Class 228 includes patents disclosing and claiming certain
steps or instrumentalities useful for a proper operation of fusion
bonding which are partially listed as follows: (1) a metallic heat
applicator (subclasses 51+); (2) seam back-up means (subclass
50 and subclass 216); (3) specialized solder pot (subclass 56);
(4) solder form (subclass 56).
A patent claiming closing of a minute opening in a single
workpiece (e.g., tipping) is proper subject matter for Class 228,
in that the periphery of a single work opening is considered to
constitute meeting faces of a single work part as required by the
definition of this class. Coating of a work part which may, incidentally,
cover small openings in the part is not considered to be proper subject
matter for this class.
RELATIONSHIP TO CLASSES INVOLVING, PER SE, METAL FUSION BONDING
Classes Of Article Making
Generally a patent claiming making of a particular article
will be found in the appropriate class directed to making of that
article except that a patent claiming performing a single fusion
bonding operation is placed in this class (228). Fusion bonding
combined with additional operations which are considered to be ancillary
to the bonding (e.g., preheating, positioning for bonding, or pretinning)
will also be found in this class (228).
Examples of such classes providing for the manufacture of
particular articles may be found in References to Other Classes,
below.
Because of the technology in the making of semiconductor and
related devices, certain art terms used to designate operations
specially recognized in that discipline are listed below which,
when combined with fusion bonding, will cause placement of a patent
in Class 29, Metal Working, and Class 438, Semiconductor Device Manufacturing:
Process, particularly subclasses 26+, 51, 55, 64+,
and 106+ for methods of packaging a semiconductor device
and subclasses 455+ for laminating or bonding plural semiconductor
substrates; see the search notes thereunder.
(1) Diffusion (not diffusion bonding)
(2) Assembling two semiconductors for an electrical function
(Note that each semiconductor may be, for example, a player, an
n layer, a chain of p or n layers or a laminated article of p and
n layers).
(3) Shaping a metal layer to form a conductor.
(4) Cutting
(5) Assembling other than to bond (i.e., other than juxtapose)
(6) Bonding to create a junction
(7) Doping
Also see References to Other Classes, below, for specific
search notes to the following:
The Class Of Wireworking
The Class Of Metal Casting
The Class Of Electric Fusion Bonding
RELATIONSHIP TO COMBINATION CLASSES
A patent claiming a combination of metal fusion bonding with
a different operation, whether manufacturing or nonmanufacturing,
is proper subject matter for Class 228, except as specifically noted
in the search notes in References to Other Classes, below, relating
to the following combination classes:
The Class Of Package Making
The Classes Including Post-fusion Treatment
RELATIONSHIP TO OTHER CLASSES
The Heating Classes:
Placement of a patent claiming heating is in the appropriate
heating class, even though the sole disclosed application of the
heat is in the production of a metal fusion-bonded product of this
class (228). In this connection, the term "heating" includes
the usually accepted auxiliary means or step such as supporting
or holding material to be heated, or causing or permitting relative
movement between the material and the heating means.
But if, in addition to the above recited heating structure or
step, a claim recites a means to further metal fusion bonding, placement
is in this class (228). Examples of such claimed limitations are:
(a) moving or guiding one work part relative to another work part,
into a position for mutual fusion bonding; (b) forcing or urging
one work portion against another work portion at the immediate zone
of fusion; or (c) moving or guiding flux or filler.
A claim to the combination of a Class 228 application (e.g., "soldering")
with supplying of heat to such applicator is considered to define
heating, proper for one of the heating classes (see paragraph 4,
below), even though details of the applicator are also recited,
such as: (a.) its alloy composition or its shape; or (b) adjusting such
applicator relative to its support.
"Means for supplying heat" may be, for example,
nothing more elaborate or detailed than a claimed pair of terminals
for connection of the applicator to an electrical circuit. See References
to Other Classes, below, for examples of classes providing for
heating.
The Work Handling Or Product Handling Classes:
The placement of patents claiming handling work for, or product
of, a metal fusion bonding operation, and also claiming fusion bonding
is in this class (228) except where the fusion bonding is recited
by name only, i.e., in terms that name but do not describe any characteristics
of a metal fusion bonding operation. The so excepted patents are
placed in appropriate classes related to material handling, per
se. See References to Other Classes, below, for examples of classes
providing for handling the work or product of a fusion bonding operation.
See References to Other Classes, below, for specific search
notes to the following classes:

The Class Of Adhesive Bonding
The Class Of Static Structures

subclass 33 , includes the combination of metal fusion bonding
apparatus with another type of manufacturing apparatus, if the other
operation occurs subsequent to the metal fusion bonding, or if the
disclosure is silent as to whether such other type of manufacturing
operation occurs before or after the bonding operation generally.
(Note that the combination of metal fusion bonding apparatus with
another type of manufacturing apparatus is found in Class 228 if
the bonding occurs subsequent to the other operation.) Class 29,

(adhesive); or (c) a metallic work part is bonded directly to nonmetallic
work part by at least slightly melting the nonmetallic material
(to effect a nonmetallurgical bond). This class (228) includes fusion
bonding wherein: (a) metallic work parts are bonded directly together;
(b) metallic and/or nonmetallic work parts are bonded together
by metallic filler; or (c) a metallic work part is bonded directly
to a nonmetallic work part where there is no melting of the nonmetal

by metal casting involving the use of a "mold".
In the apparatus portion of this class (228), in order to constitute a "mold" and

metallic material in all directions against the force of gravity
and at least a portion of such device must be readily removable
from the product of the casting operation. On the other hand, in

apparatus or that the process includes electrical current through
the work parts or the filler. Hence, placement of a patent will
be in this class (228), if such claim recites only a "welding

SECTION IV - GLOSSARY
APPLICATOR
A device by or through which heat, pressure, vibratory energy,
flux* and/or filler* may be applied directly
to the work*.
FILLER
A metallic material to be applied to the work in order
to join meeting face* together and become an integral part of
the product*.
FLUX
A nonmetallic material to be applied to the work in order
to: (1) shield the work from atmospheric oxygen or other harmful
gases, (2) chemically remove oxides or other films, or (3) otherwise
augment bonding.
MEETING FACE
That portion of a work part* intended to abut
and be fusion bonded to another similar portion of the same or another
work part.
METAL
Material which may be subjected to an operation of the class
type; an elemental metal or alloy of mixture of metals in self-shape-sustaining
state (i.e., not molten, gaseous, or powdered).
PRODUCT
Solid material or article after an operation of the class type
has been performed thereon.
| | (1)
Note. The product of one operation may constitute work* for
a subsequent operation. |
ROLLER
A tangible instrumentality having a peripheral surface which
is generated by a line revolving about an axis, said instrumentality
being disclosed as revolving about said axis so that successive
peripheral portions thereof cyclically move into and out of engagement
with a generally planar surface of another member, with relative movement
occurring between said axis and the planar surface along a direction
parallel to the planar surface, thereby producing a relative rolling
motion between the roller surface and the planar surface as contrasted
with a sliding motion, (i.e., the surfaces move in the same direction
at substantially the same linear speed so that there is no relative
linear movement between the roller surface and the planar surface
at point of engagement).
| | (1)
Note. The generating line of the peripheral surface of the
roller may have any continuous profile (e.g., straight, curved,
or irregular), and the line may have any desired inclination, other
than at right angles, relative to the axis. Thus, to be considered
a ROLLER, any and all cross-sections taken at right angles to the
axis must show a circular material engaging periphery. |
ROLLER-LIKE MEMBER
A tangible rotating instrumentality having a peripheral surface
with some, but not all, of the characteristics of a roller*.
| | (1)
Note. (a) In a first type of roller-like member the surface
is generated by a line revolving about an axis (thus the member looks
like a roller), but there is relative movement between the surface
of the roller-like member and another member to produce sliding
action therebetween; or; (b) In a second type of roller-like member
the relative movement of the roller-like member and another member
and another member produces rolling engagement between their respective
surfaces (thus the roller-like member acts like a roller), but the
surface is not generated by a revolving line (e.g., the roller-like
member is rough, gear-like, or recessed). |
WORK
Material which is intended to be subjected to a treatment of
the class type.
WORK PART
An article to be subjected to the class type operation.

| | (1)
Note. Placement into this subclass requires the disclosure
that the temporarily presented tangible object be capable of being
exchanged with a different object, or its form be capable of being changed,
for the purpose of performing a different or modified operation.
Therefore, an integral part of a machine (e.g., cam) is not included
even though there is a disclosure that the part may be removed from
the machine for purposes of replacement with a like part. |
| | (2)
Note. The tangible object, may be a workpiece, provided that
the controlled operation is performed upon another workpiece. |

| 8 | WITH CONTROL MEANS RESPONSIVE TO SENSED CONDITION |
| | This subclass is indented under the class definition. Device including means for: (1) detecting any of the following
characteristics: a state or property, a change in a state or property,
or the occurrence of a predetermined event, in any of the following:
the work, the product of a machine, the machine itself, any part
of the machine, or the environment of the machine affecting the
operation thereof; and (2) initiating (as a direct result of such
detection) a force or energy impulse other than that generated or transmitted
by the detecting means; and (3) regulating or modifying (as a direct
result of such initiation) the operation of said machine.
| | (1)
Note. This definition requires a patent to claim at least
four instrumentalities for original placement herein. One of these must
be a fusion-bonding machine or a device (e.g., work feeder, work-heater, product-handler)
necessary to the proximate function of fusion-bonding. The other
three are: (a) a senser (e.g., photo-cell system, trip-lever, pressure
diaphragm) to detect a condition as stated in (a) of the definition.
(b) an activator (e.g., an element to make or break an electric
circuit, a clutch, a valve) to cause a release of energy more than,
or different from, that accounted for by mere change in condition
(e.g., position or movement) of the senser while it is functioning;
and (c) a controller (e.g., a motor or driver for said machine or device)
to change or cause the operation of said machine or device. Therefore,
a cam follower (or senser) directly linked to a controller, whereby
follower movement directly effects controller movement, is not proper
subject matter for this subclass due to lack of an activator as defined.
On the other hand, disclosure of a cam follower that makes and
breaks an electrical circuit that energizes a motor, may be placed
herein. |
| | (2)
Note. A voluntary act of the person operating the machine
is not proper subject matter for this subclass. For example, disclosure
of an on-off switch manipulated by an operative to start and/or
stop the machine (even though the switch initiates a release of
energy) is not included herein, but is placed on the basis of claimed
features of the machines. |
| | (3)
Note. The machine that is regulated by the control means
is not limited to a fusion-bonding machine of this class. It can
be another machine associated with the fusion-bonding machine if
the claim reciting the combination of the other machine and fusion-bonding
machine is acceptable for placement into this class (228). |
| | (4)
Note. The control systems disclosed in the patents of this
and indented subclasses are similar in concept to control systems
of other classes (see the search notes below). The total operations
and the claimed combinations are, of course, different, but the
control systems, per se, found in the classes referenced in the search
notes below are usually analogous to those herein, and may be applicable
to the machines of this class (228). |

a given location. |

of the work, filler, flux or product* from a large body
thereof, thus changing at least one of the dimensions of such body. |
| | |

| | This subclass is indented under the class definition. Device including means for deforming (and defined below)
the work, filler, or flux wherein the deformation occurs prior to
the fusion bonding.
| | (1)
Note. The term "deformation" for this subclass
and the indented subclasses requires a permanent change in the shape or
size of a member without removal of material therefrom. See the
Class Definition and Lines With Other Classes and Within This Class
in Class 72 for a definition of metal deformation. |
| | (2)
Note. A single, integral instrumentality (e.g., welding bell,
may be used to deform and then fuse the work. |
| | (3)
Note. Placement into this subclass or the indented subclasses
requires only that there be some deformation of a work part prior
to fusion of that work part; the additional occurrence of simultaneous deformation
is immaterial. For example, a patent to a device for making helical tubing,
wherein a leading portion of a blank is deformed into a convolution
of a tube and then fused to a following portion of the blank prior
to the deformation of that following portion, is included herein. |

|
| | |
| 18 | COMBINED |
| | This subclass is indented under the class definition. Device to which has been added a sub-combination or assembly
which is recognized as the subject matter of some other class.
| | (1)
Note. The subject matter of the specific subclasses herein
following (19-56.5) are considered so basic to the operation characterizing
this class that they are dealt with as manifestations of that operation,
rather than as combinations. Thus, fusion-bonding devices with
means to handle or cool work or product, or provided with gauge,
indicator or stop, are considered to be so common in the art that
they do not merit the special characterization of "combined". |
| | (2)
Note. See Lines With Other Classes and Within This Class,
Relationship to Combination Classes, for a statement of the line
between combinations of apparatus proper for this class (228), and
combinations appropriate to other classes. |
| | (3)
Note. Many patents in this subclass are directed to apparatus
for performing a metal fusion-bonding operation combined with apparatus
for mechanically cleaning work or applicator. However, means for
supplying an acid to the work is considered to be fluxing, even
though a cleaning operation is also performed thereby. Patents
claiming means for performing such an operation will be found in
subclasses 33+. |

| | This subclass is indented under the class definition. Device having means for exerting a force on, or transmitting
energy to flux or filler material after said material has been applied
to the work for the purpose of changing either the quantity, density
or configuration of such material.
| | (1)
Note. Placement of patent into this and the indented subclasses
requires that the modifying means be a device independent of the
fusion-bonding means. Therefore, seam modification accomplished
by an applicator that applies flux or filler to the work will be
found in the appropriate applicator subclasses, such as 25+,
33+, etc. |
| | (2)
Note. Included in this subclass and the indented subclasses
are patents claiming a desoldering device not elsewhere classified. |

degrees of pressure. Therefore, patents in this subclass will include
those directed to devices having opposed work engaging surfaces
whose disclosed use is only to hold the work during fusion (where some
pressure will inherently be present at the area of fusion), as well
as those whose disclosure teaches the use of pressure to complete
or produce the fusion bond. |

| 101 | PROCESS |
| | This subclass is indented under the class definition. Process including the securing discrete juxtaposed meeting
faces of work parts or spaced juxtaposed meeting faces of a single work
part by adherence or coherence at the interface of the juxtaposed
areas.
| | (1)
Note. This is the generic locus for the process of bonding
work faces together. In this and the subclasses indented hereunder,
for example, is a process of securing metal parts together by welding, brazing
or soldering, a process of bonding a metal and a nonmetal surface together,
as well as a process of joining two nonmetal parts when using a
metallic filler. |
| | (2)
Note. The process of coating or casting a layer of material
on a base in which the casting or coating joins as by bonding to the
base is not considered to be surface bonding for this subclass;
however, if solidification of the cast or coated layer is followed
by a treatment, e.g., rolling or forging, to effect or improve the
bond between the base and the layer, such process, if it is otherwise
eligible, is classified in this and the indented subclasses. |
| | (3)
Note. Where the process claimed includes coating either the
meeting face of a metal work part or a nonmetal work part with a
layer of metallic or nonmatellic material and then uniting the two such
faces together by use of nonmetallic cement or adhesive or by making
of a nonmetallic part plastic and pressing the parts together so
that their meeting faces adhere to each other, the process will
be classified with the art which provides for the method of making
the joint, the coating operation being only a step in preparation
for the uniting operation. See Lines With Other Classes and Within This
Class, Relationship to Other Classes, The Class of Adhesive Bonding,
in Class 228. |
| | (4)
Note. Faces of parts are considered to be "meeting" for
this and the indented subclasses if they are bonded together, even if
it is through an intermediate filler material and even if the faces
are oppositely bevelled for the reception of filler material. |
