Patent CA-2181625-A1 (CA)
Title: Steering Control Device for Vehicle Having Continuously Variable Transmission
Inventor: KOUNO MASAKATSU
IPC: F16H9/00
Filed: 1996-07-19
Abstract: Left and right driven wheels are connected to a pair of continuously variable transmissions and independently driven. The driven wheels are increased or decreased in speed at the same rotational numbers by operation of a change lever so as to move a vehicle forward or backward. When a steering angle of a steering wheel exceeds a predetermined value, an inner wheel speed during turning of the vehicle is decreased and an outer wheel speed during turning of the vehicle is increased so as to turn the vehicle. If the steering wheel becomes greater than the predetermined value during forward running of the vehicle at a low speed, the inner driving wheels stop and the vehicle does a stationary turn. However, during forward running at a high speed or backward running of the vehicle, even if the steering wheel becomes greater than the predetermined value, the vehicle does not do a stationary turn. With this arrangement, it is possible to always obtain the optimal steering characteristic in accordance with variations of the vehicle speed or the steering wheel.

Title: Glass fiber-reinforced polycarbonate molding compositions having improved impact strength
Inventor: CHUNG JAMES Y J
IPC: C08L69/00
Filed: 1996-07-25
Abstract: The invention is based on the surprising and unexpected finding that the impact performance of a thermoplastic composition containing aromatic polycarbonate resin and glass fibers is improved upon incorporation therewith of a particular silicone rubber powder. The silicone rubber powder, added at a level of about 0.5 to 4 percent, relative to the weight of the composition, is characterized in that it contains a mixture of (a) a polydiorganosiloxane and (b) silica, said glass fibers being of the type which do not, per se, adhere to the polycarbonate matrix in which they are incorporated.
Patent CA-2183401-A1 (CA)
Inventor: ABE MASAMI
IPC: H04L1/00
Filed: 1996-08-15
Abstract: A discriminating circuit stores a flag designating a received radio signal as belonging to a traffic channel, a control channel, or an unidentified channel.  If the flag does not indicate the traffic channel, the discriminating circuit decodes the signal and detects errors on the assumption that the signal belongs to the control channel. The detected errors include convolutional code errors, which are detected by re-encoding the decoded signal, as well as errors in other types of codes.  If the flag indicates that the channel is unidentified, a counter is incremented according to the paucity or absence of errors.  When the counter reaches a threshold value, the flag is set to indicate the control channel.
Patent CA-2184305-A1 (CA)
Inventor: ITOH TERUAKI
IPC: B65G47/90
Filed: 1996-08-28
Abstract: A nozzle apparatus for sampling-dispensing a specimen comprises a nozzle body and an annular elastic bag made of an elastic member and formed to cover the outer circumferential surface at the distal end portion of the nozzle body such that fluid such as air can be sealed in the inner space of the elastic bag.  When a specimen sampling-dispensing tip is mounted to the nozzle apparatus, fluid is supplied into the elastic bag, with the distal end portion of the nozzle body kept inserted into a mounting section of the tip, so as to expand the elastic bag such that the outer circumferential surface of the bag is pressed against the inner circumferential surface of the mounting section of the tip so as to ensure a hermetic contact therebetween.  When the tip is detached from the nozzle body, the fluid within the elastic bag is discharged so as to shrink the bag and, thus, to cause the outer circumferential surface of the bag to be moved away from the inner circumferential surface of the mounting section of the tip, thereby to move the distal end portion of the nozzle body from within the mounting section of the specimen sampling-dispensing tip.

Title: Locking system for a window
Inventor: BIRO ALEXANDER J
IPC: E05C9/04
Filed: 1996-12-02
Abstract: A locking system for a window sash comprising a lock handle assembly, reciprocating rod members connected to the lock handle assembly, and rotatable cam assemblies connected to the rod members. Each cam assembly has a cam element which upon reciprocation of its respective rod element moves into and out of a cam keeper which is mounted on an adjacent window sash. Each rod member has a rod tip which moves into and out of a channel provided in the window frame. In a first operation of the lock handle assembly, the rod members are reciprocated inwardly to rotate the cam elements out of their respective cam keeper and to move the rod tips partially out of the frame channels which allows the window sash to be moved vertically within the channels. A further operation of the lock handle assembly moves the rod tips entirely out of the channels to allow the window sash to be tilted.

Patent CA-2196384-A1 (CA)
Inventor: RICHTER KEVIN R
IPC: H02G3/06
Filed: 1997-01-30
Abstract: An electrical outlet box constituted of a plastic material and having wall structure including a hexagonal recess extending into a portion of the thickness of a wall. A through-hole is drillable within the recess to facilitate passage therethrough of a screw-threaded leading end of a cord grip into the outlet box. As a lock nut is torqued down onto the leading end of the cord grip within the outlet box, a hexagonal flange of the cord grip engages within the hexagonal recess so as to inhibit relative rotation between the cord grip and electrical outlet box to obviate the need for a wrench during the torquing down of the lock nut. This structure avoids the need for a custom designed cord grip and facilitates the use of existing cord grips normally designed for utilization with metallic electrical outlet boxes.
