Patent CA-2184980-A1 (CA)
Inventor: VALLVE SERGE
IPC: F01M13/04
Filed: 1995-01-06
Abstract: A flow-controlled engine ventilation system recovers blow-by gases and lower vapor pressure hydrocarbons. In an internal combustion engine, blow-by gases generated by the internal combustion process are ventilated from the crankcase through a recovery filter (10). The recovery filter (10) has an expansion chamber (20) allowing the blow-by gases to evenly distribute themselves before flowing past the filtration medium (14). The filtration medium (14) has a large surface area and is preferably oil-soaked copper wool. A compression chamber (22) forces continued gas flow into a PCV valve (40). The PCV valve is preferably a two-stage, solenoid-controlled PCV valve. The blow-by gas is then taken in by the intake for recombustion. Hydrocarbons collected by the recovery filter are allowed to flow back into the crankcase. Overall, the ventilation system reduces emissions, increases gas mileage, and increases engine life.

Patent CA-2191376-A1 (CA)
Title: High frequency apparatus
Inventor: BRIDGES MARK
IPC: H01P1/00
Filed: 1996-11-27
Abstract: In high frequency apparatus such as for example an rf resonant cavity or a waveguide, it is often necessary to include a slot to permit a probe or other member to be located in the high frequency region and be moveable along the slot. Sealing means arranged adjacent to the slot and around the probe permits movement of the probe whilst minimising the open aperture area of the slot, hence preventing or reducing leakage through it. In one embodiment of the invention, the sealing means comprises a metallic mesh and in another it includes an elastomer material which is loaded with metallic material and/or carries a metallic mesh.

Abstract: A 3-phase overhead distribution network operates at intermediate voltage (e.g.  11 kV to 33 kV), between a high voltage supply network (at e.g. 110 kV or 275 kV) and a consumer mains system (at e.g. 110 V or 230 V). A signalling system uses signals at frequencies preferably in the region of 10 kHz to 100 kHz for signalling over the network, the signals being coupled inductively to and from the network. The signals are coupled to different phases at different points in the network cross-coupling between the phases ensures that signals coupled onto the system on one phase give adequate signal strength for detection at other points in the system regardless of which phase the detector is coupled to.

Abstract: Un appareil manuel de mise à l'échelle (1) pour une carte utilise un élément rotatif (2) ainsi qu'un capteur optique au niveau de sa pointe, afin de générer des impulsions numériques lorsque la pointe est déplacée sur la surface d'une carte. Les impulsions sont comptées par un micro-processeur. Différents totaux d'impulsions mesurent automatiquement des distances sur la carte. Le micro-processeur reçoit un nombre, par exemple le nombre de miles sur la ligne d'échelle de la carte, ensuite la pointe avance sur la ligne d'échelle. Le rapport entre le nombre de miles et le total d'impulsions est utilisé pour donner l'échelle de distance arbitraire sur la carte, par multiplication des impulsions de la pointe par le rapport. Un affichage (5) représente la distance à l'échelle. L'élément rotatif peut être une roue dans un axe ou une sphère retenue dans un élément de rétention. Le capteur présente des surfaces réfléchissantes et non réfléchissantes sur l'élément rotatif.

Filed: 1995-11-24
Abstract: An optical waveguide cross-point switch capable of full broadcast and strictly non-blocking operation. The device has a matrix of a plurality of input waveguides and a plurality of output waveguides (MxN). A reflecting surface associated with each intersection may be selectively activated to direct an optical signal on the input line to the associated output line. The reflecting surface may also be employed so as to convert an MxN matrix into a 2(MxN) rearrangeable cross-point switch. Each waveguide is capable of switching a data rate of 10 Gb/s or more. For example, with eight wavelength channels used to impart optical signals to a 16x16 switch a data rate of 1.28 Terabits/second is achievable.

IPC: B60N2/28
Filed: 1997-09-12
Abstract: The Booster Bench is a piece of dense foam which fits onto the back seat of a car and replaces conventional booster seats or can perhaps boost up a low riding infant car seat. The Booster Bench allows two to three children to ride in the back seat of a car or vehicle at the same time without the risk of injury to fingers and limbs caused by catching the same between car seats. The Booster Bench incorporates the safety of the car or vehicle seat belt with the positioning of an infant or child high enough in the vehicle to see out the vehicle's window. The advantages of the Booster Bench over the conventional three booster seats which it replaces is that there is no movement between seats which can pose a threat of pinched fingers. Like conventional booster seats, the Booster Bench raises children up in the car so they can have a better view of the road. The raised position also puts the children in a better position to use the car's original seat belts with a greater degree of safety than without the use of any child safety seats for small children. Once installed the Booster Bench also requires no adjustments to work safely. Seat belts are used as if no addition was ever made.
