Abstract: PCT No. PCT/GB95/02536 Sec. 371 Date Apr. 28, 1997 Sec. 102(e) Date Apr. 28, 1997 PCT Filed Oct. 27, 1995 PCT Pub. No. WO96/13639 PCT Pub. Date May 9, 1996This application discloses apparatus for logging the operation of a valve (10) of the type having a spindle (16) rotatable by a key (20) to effect opening and closing thereof, the apparatus including operative means (36) which are in use carried on a key (20), the operative means being operable independently of any other apparatus or electronic equipment to detect rotary motion of the key during operation of the valve. Preferably, the operative means includes sensor means (40, 42) sensitive to the earth's magnetic field, and is operative to determine rotation of the key by analysis of signals generated by the sensor means. By detecting valve operation with operative means on a key, the expense of providing detection apparatus for each valve is avoided (the total number of keys being much less than the total number of valves), as is the need to provide potentially delicate equipment in the hostile environs of the valves.

Title: Playback method and apparatus for reproducing encoded data in a reverse playback operation
Inventor: KAWAMURA MAKOTO
IPC: H03M7/36
Filed: 1996-01-30
Abstract: Encoded data is reversely reproduced by decoding each picture only once and using only as many frame memory sections as are needed in a normal playback operation.

Title: Infusion of dye using a plasticizer
Inventor: KITCHLOO PARESH V
IPC: D06P1/00
Filed: 2001-04-09
Abstract: A method of infusing a dye into the surface of an article formed of a plastic material comprises contacting the surface with a solution including one or more solvents each aggressive to the plastic material, one or more dyes and one or more substances each capable of plasticizing the plastic material. If the plastic material is polycarbonate, then the aggressive solvent may be one or more chlorinated hydrocarbons. The dye may be a photochromic dye, a cosmetic tinting dye, dyes for absorbing infrared, laser and ultraviolet radiation, or combinations thereof. A wide range of plasticizers has been investigated. The article is contacted by the solution for ten seconds to one minute; and nearly all the infused solvent is then evaporated from the article by heating. The use of one or more plasticizers reduces or eliminates bubbling or hazing of the contacted surface during solvent evaporation. The dyed article comprises a surface layer having a depth of the order of magnitude of 100 microns containing one or more dyes, one or more plasticizers and, likely, a trace amount of the one or more aggressive solvents.

Title: Hydraulic drive system for a vehicle
Inventor: PUETT EDWIN E JR
IPC: B60K17/10
Filed: 1996-04-25
Abstract: A hydraulic drive system for a vehicle includes a pressurizing circuit and a working circuit that are interconnected by suitable valving. The pressurizing circuit incorporates a fixed displacement pump which is driven by a prime mover having a nominal horsepower rating. The prime mover is shifted between an idling speed when the pressure sensed within the pressurizing circuit is within a desired range and an optimum high RPM range when the pressure within the pressurizing circuit falls below the desired range. At least one accumulator is provided in the pressurizing circuit. The working circuit includes a plurality of motor units for driving the vehicle wheels and a plurality of motor control valves which can be placed in a de-activated position to isolate the associated motor unit from the flow of pressurized fluid and an activated position wherein the motor unit aids in driving the vehicle. The vehicle is shifted between various gear ranges by controlling the activation/de-activation of the motor control valves such that, as vehicle speed and drive resistance decreases, the number of motor units being used to propel the vehicle is reduced from a maximum number of four motor units to a single motor unit. A flow control valve is provided to alter the volume of fluid flowing to the various motor units based on desired speed/acceleration parameters as determined by the vehicle operator through a conventional accelerator pedal.
