Patent CA-2197132-C (CA)
Inventor: TOEWS ROBERT J
IPC: B65G41/00
Filed: 1997-02-10
Granted: 2001-04-17
Abstract: A conveyor for particulate material of the type including a tube with a belt running through the tube and defining a return run of the belt outside the tube provides a folding action by which the length of the tube can be reduced by folding an upper portion back against a lower portion. The folding action is actuated by a hand crank which drives a chain wheel connected to a pivot pin carrying the upper portion. The pivot pin is mounted to one side of the tube which is opposite to the return run of the belt. In order to provide an extension portion of the return run which can be released to provide the length necessary for the folding action, the return run passes over a pair of rollers to form a serpentine section of the return run at the fold line of the tube. Each of the rollers is carried on a respective one of the upper and lower portions on opposite sides of the fold line to release the serpentine portion as the folding action is effected.

Abstract: A hydraulic circuit system for one-touch jack and its structure comprises mainly an inlet circuit, a return circuit and an overload protection circuit with a hydraulic cylinder, a piston rod, a sequence valve, a safety valve and a relief valve, in which the inlet circuit extends from an outer reservoir of a hydraulic cylinder via a check valve to connect to an oil chamber of a manual pump, while the oil chamber of the pump is connecting to an oil guide tube via another check valve, the said oil guide tube is inserted to an inner oil chamber formed in a piston rod to form a closed circuit. The oil chamber of the pump is connecting to an inner reservoir of the hydraulic cylinder via a sequence valve and the inner reservoir is connecting to the outer reservoir via a check valve. When the maximum effect capacity of the oil chamber of the pump is greater than or equal to the inner oil chamber of the piston rod, a single touch of the pump can raise the hydraulic jack to the required loading position for raising at no load or light load condition.

Title: Access retry method for shared channel wireless communications links
Inventor: RYAN DAVID JAMES
IPC: H04L12/28
Filed: 1999-02-23
Granted: 2002-12-31
Abstract: Each remote station in a wireless network cell that uses a collision oriented multiple access scheme, counts the number of retries attempted to gain access to the base station for a particular message. The accumulated value of the number of retries is then inserted in a retry count field of the access request message. After one or more retries, the base station successfully receives the access request message. The base station runs a common access channel allocation manager program that adaptively provides additional channels to the remote station, depending on the number of retries the remote station required to successfully transmit the access request message. In this manner, the base station has accurate information about the reduced performance that the remote stations suffer during an interval of high usage, to enable the base station to adaptively provide additional channels to the remote stations.

Abstract: A system and method allow for the periodic re-configuring of broadcast receivers to control their storage of responses to interactive applications during a polling period. A broadcast server maintains a database of interactive applications each preferably associated with a program that will be broadcast. When the program is broadcast, an interactive application is inserted into the broadcast feed and delivered to a broadcast receiver such as a television set-top box. The broadcast receiver includes a processor, memory, and other hardware necessary to execute the interactive application. When executed, the interactive application generates a response which is transmitted to a local data center at, for example, the cable head-end. Generated responses have specific types. To manage the number and capacity of the system to receive responses, priority values are assigned to responses of different types. The priority values are based on the value of the responses to the provider of the interactive application, and established with respect to total response capacity, and an estimated response volume during a palling period. These priority values are assigned or updated preferably once each polling period, and transmitted to and stored in the broadcast receivers. teach broadcast receiver uses the priority value assignments to determine if it will execute and store responses for a currently received interactive application, or reserve memory capacity for higher priority responses.

Inventor: HANIFF TARIG M
IPC: A61B5/00
Filed: 1999-08-31
Granted: 2003-11-11
Abstract: A silicon monolithic miniature intra-ocular pressure sensing probe utilizes pressure sensing piezoresistors attached to a silicon pressure sensing membrane which is directly exposed to the irrigating fluid used during an eye operation, for example. From a silicon fabrication point of view, this is a micro electromechanical (MEM) device and the integration of the piezoresistive pressure sensor directly into the cannula which is inserted into the eye is partially made possible by providing p++ etch stops to gain access for electrical connection to the piezoresistive elements arranged in a Wheatstone bridge configuration. The silicon sensing membrane forms a smooth surface to avoid turbulence and is close to the eye to minimize error.

Abstract: A toy producing a jumping or bouncing action includes an outer body (11) and an interior support structure including elongated body housing (20) having head portion (21) and supporting tail (24). A pair of leg units (23) having corresponding supporting feet (26) are slidable within body housing (20) and are joined by transversely extending leg unit bridge (70). Gear drive unit (60) rotates segment gear (62). Segment gear (62) engages gear rack (75) on leg unit bridge (70) to drive the toy toward a squatting position as leg units (23) are drawn into body housing (20). Spring (77) is coupled between leg unit bridge (70) and body housing (20) and is stretched as segment gear (62) rotates lifting the gear rack (75). When the teeth of segment gear (62) disengage gear rack (75), spring (77) causes the toy to bounce or jump. The action repeats until a control unit timer deactivates motor (50).
