A capability control apparatus for a compressor wherein gas sucked into a compression chamber is compressed due to a decrease in volume of the compression chamber. The pressure of the gas sucked into the compression chamber, in response to an increase or decrease in load, is automatically controlled by varying the volume of the compression chamber based on the pressure of the sucked gas.

A survival knife is disclosed including hook members which are securable to the knife and angled rearward toward the handle. A ring is provided for securing a line to the pommel of the handle, thereby making the knife become a grapple. Several variations of location of the hook members are disclosed including the handle, the quillon and the blade. The hook members are fixed or pivotal and may be telescoping. A skeletal knife is disclosed, with openings for securing a line, and hook members to pr...

An apparatus and/or method for generating parity digits of digital information (data) in a digital communication system is disclosed. The communication system (8) is for transferring a plurality of data intervals from an originating data source (12) to a data sink (13). Each data interval comprises one or more blocks of data and each block contains one or more bytes of data. The communication system (8) includes a temporary storage means (24) for holding the data for a limited period. Included a...

An auditory prosthesis is provided with datalogging capability whereby the use of a plurality of settings as selected by the user is maintained. The recorded datalog can be periodically read and used for revising a prosthetic prescription by altering the settings and used as a means of refining initial prescriptions of other patients whose audiometric characteristics are similar to those of the user. In one embodiment for a programmable auditory prosthesis the datalogging information includes th...

An improved fluoroelastomer composition for hydraulic seals is described which comprises a ternary mixture of a polymer including alternate fluorocarbon and hydrocarbon components joined together, EPDM (a random terpolymer of ethylene, propylene and a diene), and CTFE (an oligomer of chlorotrifluoroethylene) in a preferred weight ratio of about 85:15:10.

A camera having a photographic lens and an eyepiece lens for observing an image formed by the photographic lens, wherein when this camera is used as a telescope, the interval between the image and the eyepiece lens is shortened, while simultaneously changing the focal length of the eyepiece lens, so that the magnification of the finder is increased.

The specification discloses a method for submitting a number of documents to be printed in a limited memory word processing system in which printing is a separate, nonconcurrent foreground task with typing functions. A set of print task programs is loaded into the system. A background print process is initialized for printing one or more documents. A document is submitted for printing by entering document identification information in a print queue. The document identification information includ...

A container for cooling and/or keeping cold beverages and/or foods. The container has a double-walled structure, forming a refrigerant cavity for holding a fluid, such as water, which, when frozen, produces cooling of the beverage or food in the container. A stress-relieving diaphragm accommodates the expansion of the fluid upon chilling to prevent breakage of the container.

There is disclosed a collator which can access a desired one of a plurality of recording medium bins at any timing and which allows a maximum utilization of the plurality of bins. The collator includes a transporter for transferring recording medium to bins, a deflector for guiding the recording medium to the selected bin, an empty detector for detecting an empty state of the recording medium in the bins, and a controller for controlling the operation of the deflector such that when a predetermi...

A numerical control system executes part programs which contain parameters and arithmetic expressions containing parameters. A parameter table containing parameter values is employed to evaluate parameters and arithmetic expressions during the execution of a part program, and means is provided which enables parameter values to be changed by part program instructions or manual data entry. Macroprograms, such as canned cycles, are stored in the numerical control system in a generalized form in whi...
