Title: Hot-clock adiabatic gate using multiple clock signals with different phases
Inventor: GABARA THADDEUS JOHN
IPC: H03K19/00
Filed: 1995-06-15
Abstract: A hot clock adiabatic gate,  using CMOS technology, incorporates  an  ancillary  transistor.    The  gate  is energized by multiple clock signals of different phases to reduce power consumption.  The output logic voltage of the gate can reach full-rail voltage by allowing the CMOS technology to discharge via the ancillary transistor.  The hot clock adiabatic gate and associated transistor may be incorporated  into  various  logic  circuits,  such  as  an inverter, a memory cell, a NAND gate, an AND gate, a NOR gate, or an OR gate.  In one configuration, a CMOS inverter is controlled by four clock signals having four discrete phases.  The CMOS inverter optimally includes a CMOS gate transistor pair wherein the semiconductor channels of two ancillary transistors are in series with the semiconductor channels of the CMOS gate transistor pair.

Title: Arrangement for simulating indirect fire in combat training
Inventor: FITZGERALD MARK RICHARD
IPC: F41G3/26
Filed: 1995-09-12
Abstract: An arrangement for simulating indirect fire in military combat training exercises in which each individual exercise participant is not required to be equipped with an individual position-locating device.  The arrangement uses a technique of grouping (20, 30) the players (1-7,11-17) and equipping only one member of the group with a position-locating device (43).  The position of the single player equipped with the position-locating device is used to determine if the group is located within the area affected by simulated indirect fire.  Once the group has been determined to be within the affected area, individual players within the group assess their own casualties based on weapon-target pairing and random chance.

Patent CA-2162733-A1 (CA)
Inventor: FLATHER DAVID J
IPC: B60Q1/20
Filed: 1995-12-28
Abstract: The invention is an improvement to existing automobile headlamps of all sizes and varieties. The invention is placed on the front vertical face of an automobile headlamp manually by means of independent two - part fasteners. No tools are required as one part of the two- part fastener (the "hook" portion) is permanently adhered to the front vertical face of the headlamp and the second part of the fastener (the "loop" portion) is adhered to the molded lens. All that must be done to install the lens is that the independent hook and loop mounting devices must be mated to each other, then the protective backing must be removed from the pre-glued "hooks" and then a small degree of force is required to press the lens in place onto the face of the headlamp. The invention is a flat, transparent plastic or glass lens (may be coloured) that has bevels that are ground onto it's front face at a small angle that project upwards. The effect of this is that as the light projected by the headlight strikes the bevelled surface and is directed downwards toward the road surface at a steeper angle than the normally projected beam. This greatly reduces "glare" caused by the light bouncing back off water particles (of fog or snow) in the air during conditions of heavy fog or snow. The lens is designed to be used on the vehicle only during conditions of heavy fog or snow, and is designed to mount/remove quickly by means of up to four hook and loop fasteners adhered to the headlamp lens's face as well as adhered to the backside of the lens's spacers and this affectively secures the auxiliary lens to the headlamp lens's face by means of the interlocking hook and loop fasteners. This type of mount is designed so that the vehicle operator can use the lenses only during these conditions (of fog or snow) and remove them quickly and easily. The lenses work effectively both on the high and low beam headlight settings and do not significantly alter the effectiveness of the headlamps under normal driving conditions.

Title: Cryptographic receiver
Inventor: RARITY JOHN GILROY
IPC: H04B10/60
Filed: 1994-09-23
Abstract: A cryptographic receiver (10) includes photon detectors (52, 54, 56, 58) arranged to detect photons arriving from filters (22) and (24). A fibre coupler (14) randomly distributes each received photon (16) from an optical fibre to one of two photon channels (18, 20). The filters (22, 24) are each unbalanced Mach-Zehnder interferometers with a phase modulator (34, 44) in one arm (28, 38). The filters (22, 24) impose non-orthogonal measurement bases on photons within the respective channels (18, 20). A signal processor (60) derives a cryptographic key-code by analysis of signals received from the photon detectors (52, 54, 56, 58).

Title: Combined multiple ligating band dispenser and sclerotherapy needle instrument
Inventor: CHU MICHAEL S H
IPC: A61B17/22
Filed: 1994-10-17
Abstract: A ligating band dispenser (305) for dispensing a plurality of 1igating bands (310, 311, 312) individually during a sequence of operations for a ligating instrument. Interfitted housing (306) and piston (307) segments support a plurality of ligating bands at axially spaced locations. Retraction of the piston segment dispenses on ligating band and shifts the remaining ligating bands distally and axially. After retraction, the piston is biased forward so a next retraction dispenses another ligating band. A sclerotherapy needle (330) mounts in a sheath (320) that connects to the piston segment. A physician retracts the sheath to retract the piston. In addition the physician can advance the sclerotherapy needle through the sheath to administer a sclerotherapy agent as an alternative to ligating a lesion.

Filed: 1996-04-22
Abstract: A sealed-combustion chamber fireplace includes a combustion air to fuel adjustment device comprising an primary air-fuel mixing body having a fuel source inlet at one end and at least one combustion air inlet port disposed through a wall portion of the body. The air- fuel mixture body may be configured in the form of an air-fuel venturi, burner tube and the like to effect mixing together of the air and fuel to form a combustible air-fuel mixture. An air inlet port cover is movably disposed adjacent the air-fuel mixing body and forms an adjustable air combustion aperture by placement of the cover adjacent the air inlet port. Movement of the cover about the body effects opening or closing of the aperture, thereby effecting adjustment of the primary air to fuel ratio of the air-fuel mixture combusted in the combustion chamber. A cover arm is attached to the cover and an actuator arm is movably attached to the cover arm to facilitate adjustment of the aperture, thereby, permitting adjustment of the flame appearance during operation of the fireplace from a position outside of the fireplace.

Title: Advanced compatible polymer wood fiber composite
Inventor: SEETHAMRAJU KASYAP V
IPC: C08K7/00
Filed: 1996-06-03
Abstract: The invention relates to a composition comprising a thermoplastic polymer and wood fiber composite that can be used in the form of a linear extrudate or thermoplastic pellet to manufacture structural members. The polymer, the fiber or both can be modified to increase compatibility. The wood fiber composite structural members can be manufactured in an extrusion process or an injection molding process. The linear extrudate or pellet can have a cross-section of any arbitrary shape, or can be a regular geometric. The pellet can have a cross-section shape having a volume of at least about 12 mm3. Preferably the pellet is a right cylindrical pellet having a minimum radius of about 1.5 mm and a minimum length of 1 mm weighing at least 14 mg. The invention also relates to an environmentally sensitive recycle of waste streams. The polymer and wood fiber composite contains an intentional recycle of a waste stream comprising polymer flakes or particles or wood fiber. The waste stream can comprises, in addition to polymer such as polyvinyl. chloride or wood fiber, adhesive, paint, preservative, or other chemical stream common in the wood-window or door manufacturing process, or mixtures thereof. The initial mixing step before extrusion of the composite material insures substantial mixing and melt contact between molten polymer and wood fiber. The extruded pellet comprises a consistent proportion of polymer, wood fiber and water. During the extrusion, water is removed intentionally to dry the material to a maximum water content of less than about wt-% based on the pellet weight. To make a structural unit, the pellet is introduced into an extruder or injection molding apparatus wherein, under conditions of temperature and pressure, the composite pellet material is shaped into a useful cross-section. Alternatively, the extruded thermoplastic mass, in the form of a elongated linear extrudate without a pelletizing step, can be immediately directed after formation into an extruder or injection molding apparatus.
