Title: Deformable crip
Inventor: SCATTERDAY MARK A
IPC: A63B23/16
Filed: 1993-06-03
Abstract: The invention is a semi-resilient exercise grip (1) that has a non-resilient particulate core (4) surrounded by a resilient rubber covering (6).

Title: Thermal nose protector for skier
Inventor: MCDONALD NEIL
IPC: A61F9/02
Filed: 1995-01-25
Abstract: A thermal nose protector for use in subfreezing climates, e.g. by an alpine skier with ski goggles. The thermal nose protector consists of a flexible shield sheet material sized to conformingly fit over the skier's nose and having at least a first and a second layer. The first layer is made from a soft, thermally insulating material for direct engagement with the skin of the skier's nose. The second layer is of the multiple-hook type for separable gripping engagement with a corresponding portion of the foam-like, peripheral, interior strip of the ski goggles. The flexible shield sheet extends beyond the tip of the skier's nose whereby a substantially open air pocket is defined by the nose-covering the shield sheet beneath the skier's nose and ahead of the skier's mouth, wherein an air breathing channel is formed coextensively of the open air pocket for promoting air breathing from the nose of the skier. The air breathing channel extends generally transversely of the direction of displacement of the skier whereby the nose of the skier is thermally protected from incoming wind.

Title: Method and apparatus for producing a porosity log of a subsurface formation
Inventor: ALLEN LINUS S
IPC: G01V5/10
Filed: 1993-08-09
Abstract: A borehole logging tool (10) is lowered into a borehole tra-versing a subsurface formation and a neutron detector (19) mea-sures the die-away of nuclear radiation in the formation. Intensity signals are produced representing the die-away of nuclear radiation as the logging tool (10) traverses the borehole. A signal processor (17), employing as least one neural network, processes the intensity signals and produces a standoff corrected epithermal neutron life-time signal to correct for standoff from the borehole wall (24) en-countered by the detector (19) as the logging tool (10) traverses the borehole. The signal processor further generates a porosity signal from the standoff corrected epithermal neutron lifetime signal de-rived from measurements in borehole models at known porosities and conditions of detector (19) standoff. A log is generated of such porosity signal versus depth as the logging tool (10) traverses the borehole.

Title: Transmission spring loaded shift device
Inventor: GENISE THOMAS A
IPC: F16H61/34
Filed: 1995-08-03
Abstract: A transmission shifting system for a gear change transmission where an actuator responding to a control signal is used to axially displace a secondary shift rail thereby preloading a spring acting upon a primary shift rail where a coupling element permits relative motion between the secondary shift rail and the primary shift rail until gear synchronization or a torque break occurs allowing the desired gear shift to occur. The relative motion which results in a spring preload force to be generated on the primary shift rail continues until the secondary shift rail contacts the portion of the coupler adjacent to a primary flange formed as part of the primary shift rail whereupon the actuator is solidly linked to the shift rail and a shift fork.

Inventor: HAMILTON JEFFREY S
IPC: H04N19/60
Filed: 1995-10-11
Abstract: A method and apparatus are provided for changing the compression level of digital information, such as digital video information. After having been compressed by a first compression scheme that provides quantized transform coefficients, the digital information is partially decompressed to recover the transform coefficients as they were prior to quantizing. The transform coefficients are then requantized at a different compression level. Complexity and expense are reduced by only partially decompressing and requantizing the previously compressed information to modify its compression level without the need to provide components such as a motion compensation processor and frame store that would be required for full decompression of the information prior to recompression.
