Usually a word consists of one or more letter characters that taken together as a group may also be spoken by people of a national or ethnic folk, but especially for purposes of this class, a word may consist of more number characters as well as letter characters, the words then conveying information in a cryptos:graphic "language".

WORKING CHAMBER (CLASS 091)
A chamber into which motive fluid is introduced or from which motive fluid is withdrawn (vacuum) to cause the working member to move to perform work, the chamber expanding or contracting incident to the movement of the working member. A chamber of a vacuum motor to which atmospheric air has free ingress and egress without any control thereof is not a working chamber. However, a chamber of a vacuum motor in which atmospheric air acts and some control is exercised over the atmospheric air is a working chamber.

The space in an expansible chamber device which includes the working member and which is adapted to receive working fluid for acting upon the working member, or for being acted upon by the working member.

WORKING CHAMBER (CLASS 418)
The space in an expansible chamber device which includes the working member and which is adapted to receive working fluid for acting upon the working member or for being acted upon by the working member, the chamber expanding and contracting incident to movement of the working member.

A fluid material (gas or liquid) which contacts the runner and causes it to move, or has energy added thereto by a driven runner.

WORKING FLUID (CLASS 416)
An unconfined or undirected fluid which acts or reacts with a working member* such that movement of the fluid causes relative movement of the member or movement of the member causes relative movement of the fluid. The fluid may be quiescent or flowing and either natural (e.g., wind) or artificial (e.g., combustion gas). A patent including claimed means for confining, guiding or directing the fluid to or from an impeller* will be classified elsewhere. A waterfall has been determined to be directed fluid and an impeller claimed in combination therewith is classified elsewhere. See References to Other Classes, above.

WORKING FLUID (CLASS 418)
The fluid (expansible or inexpansible) which is introduced into and withdrawn from the working chamber of the rotary expansible chamber device either to act upon or be acted upon by the working member. Fluid which is withdrawn from the working fluid supply for perfecting the operation of the device is considered to be working fluid even though it never enters the working chamber of the device. A fluid combined with working fluid introduced into and exhausted with the working fluid from the working chamber of the device used merely to perfect the operation of the device (i.e., cooling, sealing, lubricating, etc.), is considered to be a nonworking fluid.

WORKING MEMBER (CLASS 091)
A movable wall of the expansible chamber to which motive fluid is applied or to which atmospheric air is applied in the case of vacuum motor, said wall moving as a result of the application of the motive fluid and in so moving doing work for utilization by means other than the motor or some part thereof. In a reciprocating motor this term is generic to both a moving piston and a moving cylinder. The working member is considered to include the movable wall to which motive fluid is applied as well as all parts which are rigid therewith, e.g., piston rod, etc. However, a pair of separate movable walls disposed in separate working chambers (i.e., chambers which are not in fluid communication during at least some part of the operation of the motor), even though rigidly connected together, are considered to be plural working members if the application of motive fluid thereto urges both walls in the same direction. A working member has a single working surface which surface may have two or more relatively movable faces so long as adjacent faces are always an extension of each other, e.g., flexible diaphragm or bellows, etc.

WORKING MEMBER (CLASS 092)
The wall portion of the expansible chamber of an expansible chamber device which is acted upon by the working fluid to be moved thereby to change the volume of the chamber and produce a mechanical force output, or which, having a mechanical force applied thereto is moved to change the volume of the chamber to either draw fluid into or expel fluid from the chamber. The term includes the movable wall portion and any part which is immovably fixed thereto (e.g., piston rod).

WORKING MEMBER (CLASS 416)
A unitary means of which at least one surface functions to act or react with a working fluid* such that movement of the means causes movement of the fluid or movement of the fluid causes movement of the means. The working member is most commonly designated as a blade, bucket or vane.

WORKING MEMBER (CLASS 418)
A movable member in a rotary expansible chamber device having a surface portion disposed to either receive the energy of a working fluid directed thereagainst for moving the member to thereby produce a mechanical force output, or which, may move a working fluid by the application of a mechanical force to the movable member whereby fluid is admitted into and exhausted from the expansible chamber. The working member may include a movable vane thereon having a surface portion for either receiving energy from or energizing a working fluid passing through the expansible chamber.
