Patent CA-2149842-A1 (CA)
Title: Backpack for heavy bulky footwear
Inventor: KLIOT EUGENE
IPC: A45F3/04
Filed: 1995-05-19
Abstract: A backpack for carrying bulky, heavy footwear such as inline skates, conventional roller skates, ice skates or ski boots is provided.  Preferably, a backpack for carrying inline skates is provided.  According to the invention, the backpack includes a left and right opposed trapezoidal compartments.  These compartments have a generally rectangular back face and a narrow width.  The left and right compartments are angularly joined together at the front base portion of the compartments to form an isosceles tri-angle therebetween.  The joined right and left trapezoidal compart-ments define a portion of the front face of the backpack.   A piece of luggage material such as tight weave nylon is used to complete the front of the backpack by closing off the top of the area between the left and right trapezoidal compartments.  The left and right trapezoidal compartments are rather narrow and in fact are only wide enough to receive the narrow part of a boot or skate.          This prevents shifting of the footwear when carried.  The compart-ments have a sufficient height for receipt of the blade portion of a skate and/or of the top portion of a bulky boot, for example, a ski boot.  In addition, the compartments have a sufficient depth to receive the blade portion of a skate.
Patent CA-2151004-A1 (CA)
Inventor: MODRAK JAMES P
IPC: D01F6/92
Filed: 1995-06-05
Abstract: The invention provides melt-spun polyolefin/-polyarylate alloy fibers having an elevated softening point.  These fibers are useful in staple lengths for the reinforcement of synthetic geoways (e.g., roadways, runways), especially those fabricated from asphalt-based pavements.  The improved softening point of the fibers allows their incorporation into the hot-mix pavement used to fabricate and repair such surfaces without degradation of the fibers by the elevated temperatures found in plants for these manufacture of hot-mix pavements.  This invention also provides an improved process for making melts of such allows.

Title: Multi-stage transponder wake-up, method and structure
Inventor: SHARPE CLAUDE A
IPC: H04B1/59
Filed: 1995-08-14
Abstract: A system and method which conserves energy in the operation of a transponder or tag (14) by providing that the transponder (14) be enabled or awakened in multiple stages. A threshold detector (62) is provided which measures the power level of received RF energy. If the RF energy received by the detector (62) exceeds a pre-determined level, the transponder (14) then employs a modulation detector (64) to ascertain whether it has been awakened by a valid interrogation signal from an interrogator (12) or whether the RF energy received was merely a spurious burst of RF energy from some other source. If a pre-determined modulation is detected by the modulation detector (64), the transponder (14) is then fully activated to its normal operational state.

IPC: G06F13/14
Filed: 1990-03-16
Abstract: A Command interface includes ports for transferring information between a host processor and at least one intelligent subsystem which may have attached devices.  A Command interface port receives either a direct command or an indirect command from the host processor, which commands are indicative of a type of operation to be performed by the one subsystem or an attached device.  An Attention port receives a code from the host processor which is indicative of which one of the direct command or the indirect command is received at the Command Interface port, and which is also indicative of which of the one intelligent subsystem or a device is to execute the command.

Title: Fuel cell system with reforming device
Inventor: HUPPMANN GERHARD
IPC: H01M8/247
Filed: 1995-10-27
Abstract: The invention provides a fuel cell system with stacked fuel cells arranged in a fuel cell block, with an inlet for fresh combustion gas at the anodes on one side of fuel cell block and an outlet for the used combustion gas on the opposite side, as well as inlet for fresh cathode gas at the cathodes on another side of fuel cell block and an outlet for used cathode gas on the opposite side.   A reforming device, which utilizes heat given off in the fuel cell reaction to reform the fresh combustion gas fed to the anode inlet of fuel cells, has an area provided with a catalyst.   An inlet to the catalyst area receives fresh combustion gas to be reformed, which passes through the area  containing  the  catalyst,  in which the  reforming process takes place,  and exits through an outlet.   The reforming device is designed as a heat exchanger located in the exhaust gas stream directly behind the fuel cell block.          Exhaust gas from the fuel cells is guided through the heat exchanger as  a heating gas  for heating the  reforming device.

Patent CA-2165322-A1 (CA)
Inventor: LI YAO-TZU
IPC: F25C1/14
Filed: 1994-06-16
Abstract: Une machine (75) permettant de congeler ou de refroidir un liquide en continu pour obtenir une pâte fluide (20) constituée de liquide et de cristaux congelés, reçoit le liquide en continu par le haut d'un tube de transfert de chaleur (1) disposé verticalement. Un réfrigérant (39) coulant sur la surface externe (1b) du tube s'évapore en formant un flux de vapeur/mousse, ce qui provoque la congélation du liquide sur la surface interne du tube (1a). Une tige de raclage (9), de préférence supportée uniquement à sa base, tourne sur la surface interne (1a) pour déloger mécaniquement les cristaux congelés et pour étaler le liquide. Un additif ajouté au liquide, tel que l'éthylène glycol (dans l'eau) aide à ce délogement. Dans une forme de réalisation, un guide mécanique pour l'écoulement (35) entourant la surface externe produit un écoulement (39) pelliculaire ascendant rapide du réfrigérant en ébullition, ce qui augmente le transfert thermique. Un entraînement orbital (4-8, 107, 108, 109, 110, 111) assure la rotation de la tige de raclage (9). Dans une forme de réalisation, l'entraînement orbital comporte une paire de plaques horizontales (101, 102) couplées entre la tige de raclage (9) et au moins une manivelle excentrée (109, 109'). Dans une autre forme de réalisation, l'entraînement comporte une paire de contrepoids (7, 7) couplés rigidement au tube de transfert de chaleur que des moteurs indépendants (8, 8) font tourner en synchronisation de phases, grâce à la conception dynamique du système.

Filed: 1994-09-21
Abstract: In order to supply a combustion installation, such as an internal combustion engine (1), with a second type of fuel, in particular LPG, in addition to a first type of fuel, such as petrol, a second control unit (12) is coupled to the first or original electronic control unit (8) of the engine. In response to first control signal values emitted by the first control unit (8), said second control unit (12), during operation on LPG, emits second control signal values for metering the LPG supply.  With this arrangement the first control signal values received from the first control unit (8) are compared with the values recorded by the second control unit (12) during operation on petrol. The second control signal values emitted by the second control unit (12) are now so adjusted that, during operation on LPG, the first control signal values are still kept within a predetermined range (operating range) of the first control signal values recorded during operation on petrol.
