Patent CA-2112714-A1 (CA)
Inventor: DOLAN ROBERT A
IPC: B60T11/10
Filed: 1993-12-31
Abstract: In a breakaway trailer brake activating mechanism mounted on a trailer surge brake actuator, one end of a tension coil spring is attached to the breakaway activating mechanism while the other end of the spring is connected to an intermediate link on a breakaway chain. The connection is such that a surplus, predetermined number of breakaway chain links, forming a slack section of the breakaway chain, are connected between the ends of the spring. The spring prevents the slack section of the breakaway chain connected between the ends of the spring from being pulled tight so as to allow for tow vehicle turns even if a safety chain is incorrectly secured. Thus, during a sharp turn of the tow vehicle, the spring will allow the reserve links of the slack section of chain to extend but not so far as to cause the trailer brake to be activated. Should the trailer become separated from the towing vehicle during towing, however, the force exerted on the breakaway chain extends the spring to the point that the slack section of the breakaway chain is pulled tight thereby causing application of the trailer surge brakes by the breakaway brake activating mechanism.
Patent CA-2114261-A1 (CA)
Title: Apparatus for Centering a Wheel on a Hub
Inventor: ROGERS LARRY K
IPC: B60B3/16
Filed: 1994-01-26
Abstract: A centering apparatus for centering a detachable vehicular wheel with a central opening on a hub. The one-piece centering apparatus fits in an annular groove in the hub pilot boss. The one-piece centering apparatus may be in the shape of a ring, with bendable and resilient fingers extending outwardly from the ring at an angle away from the outer end of the pilot boss. As the wheel is mounted over the hub pilot boss, a flange at the wheel central opening presses against the fingers on the ring. This causes the fingers to bend slightly to compensate for any interference fit. The resilient action of the fingers keeps the wheel centered on the hub. The wheel is then bolted to the wheel assembly. In other embodiments, the centering apparatus has a cross-section in the approximate shape of a "V", "U", "N", or "M", one leg of which serves as the bendable and resilient finger. The fingers may be replaced by a continuous member extending around the circumference of the pilot boss. The centering apparatus may also be a coiled wire in the shape of a toroid. The centering apparatus alternatively can be retained in an annular groove in the margin of the wheel central opening, with the bendable resilient fingers extending inwardly to press fit with the hub pilot boss and center the wheel on the hub. Various materials may be used for the centering apparatus.

Title: Method and system for managing ownership of a released synchronization mechanism
Inventor: TOUTONGHI MICHAEL
IPC: G06F9/46
Filed: 1994-12-20
Abstract: A method and system for managing ownership of a released synchronization mechanism is provided. In a preferred embodiment, a number of entities, such as threads, are attempting to acquire the synchronization mechanism when the synchronization mechanism becomes available. Each of the entities has a priority indicator that indicates the relative urgency of the attempt by the entity to acquire the synchronization mechanism. The method and system first identifies one of the entities attempting to acquire the synchronization mechanism that has the priority indicator that indicates that its attempt to acquire the synchronization mechanism is of the highest urgency. The method and system then determines whether any entity attempted to acquire the synchronization mechanism during a foregoing selected period of time. If an entity has attempted to acquire the synchronization mechanism during the selected period of time, then the method and system assigns ownership of the synchronization mechanism to the identified entity. If no entity has attempted to acquire the synchronization mechanism during the selected period of time, then the method and system defers the assignment of ownership of the synchronization mechanism to a later time.

Title: Pulsed electronic article surveillance systems
Inventor: BALCH BRENT
IPC: G08B13/24
Filed: 1995-06-13
Abstract: An electronic article surveillance (EAS) system includes a transmitting antenna, a driver operable for exciting the transmitting antenna, a receiving antenna and circuitry connected to the receiving antenna for improving the quality of transmissions from the transmitting antenna. The driver excites the transmitting antenna at a preselected system operating frequency and the circuitry connected to the receiving antenna improves the quality of transmissions from the transmitting antenna by lessening harmonics of the operating frequency in the transmissions. The harmonics are attributable to protection diodes connected to the receiving antenna for limiting voltages impressed thereon and otherwise adversely impacting on the receiver tag signal processing circuitry. The harmonic lessening circuitry is connected in parallel with the protection diodes and is operative to lessen protection diode harmonic generation.
