Title: Back wheels twin axles drive system for compact vehicles
Inventor: VILANDRE GILLES
IPC: B60K17/04
Filed: 1998-03-19
Abstract: The new invention takes advantage of a dual axles drive system, on the rear wheels traction of a vehicle, whereby the first axle the "back-up axle" is powered to turn in a backward direction which power is than transferred to the "wheels drive axle" located in front of the first axle, by means of transfer gears, one on each sections, that changes the backward direction of the first axle to a forward wheels drive on the second axle, gaining thru said combination, the advantage of a downward theist of the drive pinion and driveshaft to which vehicle is attached, thus preventing the overturning of said vehicle when the wheels are blocked while the engine is running and clutch is not released in time as can happened in conventional one axle drive system of existing compact vehicles.     The object of this invention is to replace the single axle driving system, presently used by an integrated twin axle driving system on rear wheels of compact vehicles such ase jeeps, farm tractors, or «A.T. V.» all terrain vehicle, in order to take advantage of a backward drive combine with a gears's system which can prevent the overturning of vehicles in certain instances.
Patent CA-2228943-A1 (CA)
Inventor: WEISSENBORN RICHARD K
IPC: A63C11/06
Filed: 1998-02-02
Abstract: An apparatus for the sharpening and/or bevelling of either a ski or a snowboard side edge or base edge. The apparatus comprises a guide adapted to be held by the hand and moved lengthwise along an edge portion of a ski or snowboard while in contact with a surface thereof. The guide includes means for securing a file or the like thereto at any one of a plurality of desired angular positions relative to the lengthwise direction of movement of the guide during use. Thus, a desired portion of the file length may make contact with the edge portion of the ski or snowboard and/or the teeth on the file may be oriented at a desired angle to the lengthwise direction of movement. This assists the operator in producing a consistent file cut and efficient edge sharpening or bevelling regardless of the degree of shaping, side cut or camber of the ski or snowboard. The means for securing comprises suitable means for clamping the file or the like in the guide in any one of the desired angular positions. Additionally, the guide includes special means to angularly orient the file or the like in a plane transverse to said lengthwise direction when positioned at the side edge portion of the ski or snowboard to establish a desired side edge geometry or bevel angle.

Title: Clear cosmetic gel composition
Inventor: LEE WILSON
IPC: A61K8/28
Filed: 1996-08-15
Abstract: Disclosed is a clear cosmetic gel composition in the form of a water-in-oil emulsion, and methods of forming and of using the composition. The composition has a water-based phase containing water, a cosmetically active ingredient, and at least one coupling agent;  and an oil-based phase containing a material having a refractive index in the range of 1.40 - 1.50, silicone fluids and an alkoxylated, alkyl substituted siloxane surface active agent (e.g., dimethicone copolyol). The composition has a refractive index in a range of 1.4026 to 1.4150. Where the cosmetically active ingredient is an antiperspirant active ingredient, the composition can be an antiperspirant gel (e.g., soft gel) composition. In the refractive index range of the present invention, increased amounts of, e.g., antiperspirant active ingredient, and other high-refractive-index materials providing cosmetic benefits, can be incorporated in the water and oil phases of the composition while still achieving a clear composition. The composition can also include polypropylene glycols (e.g., tripropylene glycol), as part of the water-based phase, to provide a composition having reduced tackiness and reduced whitening (decreased residue); this composition is also mild (reduced skin irritation potential) relative to comparable commercial products.

Title: Spread spectrum chip shift keying modulation/demodulation system and method
Inventor: SHOCKEY BRUCE EDWARD
IPC: H04B1/707
Filed: 1998-02-26
Abstract: A modulation/demodulation system and method comprising transmitting structure having first and second PN generators which produce distinct, synchron ized, first and second PN sequences. A tapped delay line generates a plurality of symb ols from the second PN sequence, each symbol corresponding to an offset of the secon d PN sequence by one or more chips from the epoch of the first PN sequence. A plurality of output taps are associated with the lapped delay line, with each ta p corresponding to one of the symbols. A symbol selection device associated with t he output taps selects from amongst the symbols based upon one or more message sign al bits. The selected symbols and first PN sequence are applied to separate channel s of a modulator to modulate a carrier signal. At a destination, first and second loc al PN generators generate first and second PN sequences which correspond to the first and second PN sequences in the transmitting structure. A tapped delay line connected to the second local PN generator generates a plurality of symbols which correspond to the symbols in the transmitting structure. An analog baseband signal is recovered fr om the modulated carrier signal and sampled, and each sample is multiplied by the symbo ls from the tapped delay line. The resulting products are filtered, summed and comp ared to a predetermined threshold, and the sum which exceeds the threshold is convert ed to a bit pattern. Consecutive bit patterns are combined to produce a serial data st ream which corresponds to the message signal.

Patent CA-2235026-A1 (CA)
Title: Current control for an analog optical link
Inventor: WOODWARD SHERYL LEIGH
IPC: H04B10/293
Filed: 1998-04-16
Abstract: A control circuit for an injection laser provides a pre-bias current which prevents clipping induced errors in the laser output. An analog modulating signal is provided directly to the laser which receives the sum of a feedback current (Ifb) and a current source (Io) as the pre-bias current (Ipb).  A monitor diode detects the laser light output and provides a current (Idet).  A feedback circuit operates in a limited dynamic range, e.g. I~ +/- 40 mA or is incapable of outputting a negative current (Ifb>0). The feedback circuit responds to changes in Idet and adjusts the laser pre-bias current to hold Idet equal to a preset value, which effectively holds the laser's average output power constant. If the pre-bias current necessary to hold Idet fixed falls below some minimum level, Imin, the feedback circuit will run out of dynamic range and the laser's average power will increase. By preventing Ipb from falling below Imin clipping induced errors and distortion are avoided.

Title: Integrated voc entrapment system for regenerative oxidation
Inventor: BLAZEJEWSKI EDWARD G
IPC: B01D53/44
Filed: 1997-05-20
Abstract: Regenerative thermal oxidizer in which a gas such as contaminated air is first passed through a hot heat-exchange bed and into a communicating high temperature oxidation (combustion) chamber, and then through a relatively cool second heat exchange bed. The apparatus includes a number of internally insulated, ceramic filled heat recovery columns topped by an internally insulated combustion chamber. Process air is fed into the oxidizer through an inlet manifold containing a number of hydraulically or pneumatically operated flow control valves (such as poppet valves). The air is then directed into the heat exchange media which contains "stored" heat from the previous recovery cycle. The process air is heated to near oxidation temperatures. Oxidation is completed as the flow passes through the combustion chamber, where one or more burners are located. The gas is maintained at the operating temperature for an amount of time sufficient for completing destruction of the VOC's. From the combustion chamber, the gas flows vertically downward through another column containing heat exchange media, thereby storing heat in the media for use in a subsequent inlet cycle when the flow control valves reverse. The resulting clean air is directed via an outlet valve through an outlet manifold and released to atmosphere at a slightly higher temperature than inlet, or is recirculated back to the oxidizer inlet. An integrated VOC entrapment chamber entraps any VOC's that leak out during cycling, and recycles them back to the oxidizer inlet for further processing.
