IPC: B23P6/02
Filed: 1994-06-20
Abstract: Outil abrasif de surfaçage destiné au reconditionnement de la surface des paliers d'un arbre à came solidaires dans une culasse. L'outil comprend un corps (1) de forme allongée présentant une surface externe (2) dont au moins une partie constitue la surface abrasive (3) et, au minimum un manche (5) à une extrémité de ce corps, ce dernier comportant au moins une partie cylindrique (8) dont la section transversale latérale présente un diamètre correspondant au diamètre de palier nécessaire défini par la surface des paliers solidaires de l'arbre à came.

Title: Dispositif de protection pour systeme de chauffe-eau fonctionnant a l'energie solaire
Inventor: TASSICKER PHILLIP GRAHAM
IPC: H01H37/00
Filed: 1994-08-09
Abstract: L'invention se rapporte à un dispositif de protection sensible à la température (8) pour un chauffe-eau fonctionnant à l'énergie solaire avec apport supplémentaire d'énergie électrique, ledit dispositif se caractérisant par un premier et un second thermostat (T1, T2) se remettant automatiquement à l'état initial, par un organe élastique (16), par un actuateur (30), par un premier et un second commutateur (20, 22) et par une résistance fusible (24). La résistance fusible (24) maintient l'organe élastique (16) à l'état comprimé. En cas de défaillance du premier thermostat (T1) résultant en un apport continu d'énergie vers le suralimentateur électrique et en un changement d'état du second thermostat (T2), le premier commutateur (20) va changer d'état, ce qui fait fondre et désintègre la résistance fusible (24). L'organe élastique (16) qui est alors relâché, amème l'actuateur (30) à changer l'état du second commutateur (22), interrompant tout apport d'énergie vers le suralimentateur électrique jusqu'à ce que la résistance fusible (24) soit remplacée et l'organe élastique (16) remis à l'état initial manuellement.

Patent CA-2001395-A1 (CA)
Inventor: HAMMERSTEDT ROY H
IPC: A01N1/02
Filed: 1989-10-24
Abstract: A noningestible separation barrier having one or more pores or micropores  (of  one or more diameters) therein,  with the pores or micropores being initially plugged with one or more materials selected for its/their solubility and/or integrity characteristics relative to certain environmental conditions. Ordinarily, the pores or micropores of the noningestible separation barrier are initially  filled  with  at  least  one  material  having greater   erodibility,   under  a   given  environmental condition, than the material constituting the separation barrier itself.  The combination of the release rate (if any) or other membrane characteristic of the separation barrier,  combined with the release rate and/or erosion life of the plugged pores, enables complex separations including variable release of cells, colloids, solutes or solvents over time, such as when the plugged pores remain intact until erosion is triggered by an environmental change such as solvent addition or ionic conditions or pH or  thermal  change.    Particular  applications  include specialized   receptacles   and   protocols   for   the preservation of rooster sperm and turkey sperm for use in commercial artificial insemination applications.

Patent CA-2013700-A1 (CA)
IPC: B60R21/01
Filed: 1990-04-03
Abstract: An air bag firing circuit comprises a firing path including in series a safing sensor, a squib, and a crash  sensor.    Each  sensor  comprises  normally-open switch means operated by an inertial mass and shunted by a resistor.  A battery maintains a known voltage across the firing path while suitable control means checks the integrity of the firing path by reading and comparing the voltages achieved at various points thereabout.  The control means further tests each sensor individually by sequentially operating suitable test means incorporated therein, such as means for biasing the inertial mass of each sensor towards its switch means to operate same, while  determining  the  effect of such testing on the voltages  achieved about  the  firing path.   Upon  the detection of a sensor failure, the malfunctioning sensor is removed from the firing path as by operating low-resistance shunt means therefor, or by operating means incorporated within the sensor for operating the switch means thereof without regard to acceleration, such as means for biasing its inertial mass towards its switch means  to  close  same,  thereby  ensuring  continued protection of the vehicle passengers until the sensor is serviced or replaced.   If the malfunctioning sensor is the  high-threshold  crash  sensor,  the  control  means operates means on the low-threshold safing sensor to increase the threshold thereof upon removal of the crash sensor  from  the  firing  path,  thereby  providing continuing protection for vehicle passengers.

Title: Sequential parity correction
Inventor: CHAN RAYMOND S
IPC: G06F11/10
Filed: 1990-05-18
Abstract: An apparatus and method of detecting parity errors includes checking data and associated parity in parallel with use of that data by an arithmetic logic unit.  Upon detection of an error, the arithmetic logic unit will pass the data, unchanged, and associate that data with a new parity that is generated from the data.  The data and new parity is then returned to the input of the arithmetic logic unit for processing.  During the detection and reassociation sequence, downstream registers are paused to allow the reassociation of data and parity to take place, and to allow the data then be processed by the arithmetic logic unit.

Title: Idle speed control apparatus and method for an internal combustion engine
IPC: F02D41/08
Filed: 1990-10-05
Abstract: ABSTRACT OF THE DISCLOSURE An  improved  idle  speed  control  apparatus  for  an internal combustion  engine capable  of effectively  preventing instantaneous fluctuations  in  the number  of revolutions  per minute of the  engine when  the engine load is  instantaneously changed during  engine idling,  thereby improving the  driver's driving  sensation.   A  bypass passage  is connected  with  an intake manifold of  the engine for supplying  intake air to the engine  while   bypassing  a  throttle   valve  in  the  intake manifold.  A bypass  air controller  is disposed on the  bypass passage  for  controlling  the  amount  of bypass  air  flowing therethrough.   In one  embodiment, the  bypass air  controller operates  such   that   when  the   engine  load   is altered instantaneously during the engine  idling, the amount of intake air is gradually changed from a first  level suited to a first operating  condition of  the  engine  load to  a  second  level suited to a second operating condition of  the engine load.  In another embodiment, the amount of intake  air is first changed swiftly from  the  first  level  to  a third  level,  and  then gradually from the third level to the second level.
