Title: Currency recycling automated banking machine media gate
Inventor: OWENS MARK
IPC: G06Q20/00
Filed: 1998-11-19
Abstract: An automated banking machine (10) identifies and stores documents such as currency bills deposited by a user. The machine then selectively recovers such documents from storage areas and dispenses them to other users. The machine includes a central transport (70) in which documents which are deposited are oriented and identified. Such documents are then routed to storage areas in recycling canisters (92, 94, 96, 98) when a user subsequently requests a dispense of documents. Documents are selectively picked from the storage areas and delivered to the customer. Media gates (116, 118, 120, 122) are used to selectively direct documents between remote transport segments (108, 110, 112, 114) and canister delivery transports (124, 126, 128, 130). The media gates operate by selectively directing documents through an intersection (421) in engagement with transversely offset belt flights (396, 422). A diverter member (430) selectively deforms the belt flights of the remote transport segment so as to guide documents to and from an associated canister delivery transport.

Patent CA-2312948-A1 (CA)
Title: Turbine engine with a thermal valve
Inventor: PATEL KIRITKUMAR
IPC: F16K17/38
Filed: 1998-12-04
Abstract: A turbine engine having interior cavity (73) sealed by a thermally controlled valve (80) is disclosed. The cavity (73) is defined by at least one cylindrical wall portion (74). The valve comprises an opening (82) in the cylindrical wall portion and a cylindrical band (83), coaxial and interior to the wall portion.  The cylindrical (83) band is made of material having a higher thermal coefficient of expansion than the wall portion. As the temperature of the engine increases, the band (83) expands at a higher rate than the wall (74), thereby sealing the valve. As the temperature decreases, the band contracts thereby opening the valve. The valve may be used to permit a cavity to be pressurized at low temperatures. The pressure in the cavity may exert a forward load on a thrust bearing, suspending the engine shaft.

Title: Augmentation of electrical conduction and contractibility by biphasic cardiac pacing administered via the cardiac blood pool
Inventor: MOWER MORTON M
IPC: A61N1/36
Filed: 1999-01-13
Abstract: Augmentation of electrical conduction and contractibility by biphasic cardiac pacing. A first stimulation phase is administered to the cardiac blood pool.  This first stimulation phase has a predefined polarity, amplitude and duration. A second stimulation phase is then administered to the cardiac blood pool. This second phase also has a predefined polarity, amplitude and duration. The two phases are applied sequentially. Contrary to current thought, anodal stimulation is first applied and followed by cathodal stimulation. In this fashion, pulse conduction through the cardiac muscle is improved together with the increase in contractibility.

The electrical device is connected in parallel to the first electrical outlet on the load side of the sensor.
Patent CA-2330768-A1 (CA)
Inventor: BREWER DAVID
IPC: H04B10/275
Filed: 1999-04-27
Abstract: A loop network hub port (300) with an automatic bypass feature. The automatic bypass feature causes the hub port (300) to enter a bypass mode upon detection of a specified loop initialization sequence (316) from a node port (310) attached to the hub port (300). The hub port (300) does not propagate loop failure initialization data generated by the attached node port (310) upon failure of a data channel from the hub port (300) to the node port (310). The hub port (300) replaces loop initialization data with buffer data (324) and conceals the node port (310) failure from the remainder of the loop. Upon detection of the loop failure initialization sequence received from the node port (310), the hub port (300) enters a bypass mode, connecting input (302) to the output (328) of the loop until a recovery sequence is received.
