Patent CA-2101290-C (CA)
Title: Eas system with improved processing of antenna signals
Inventor: PLONSKY CHRISTOPHER B
IPC: G08B13/24
Filed: 1993-07-26
Granted: 2002-01-01
Abstract: An EAS system in which first and second received signals are independently front-end processed to produce third and fourth signals indicative of the absolute values of the first and second processed signals. The third and fourth signals are then combined and the combined signal passed to a tag evaluation processor for time and frequency domain processing for evaluating whether a tag is present in an interrogation zone. The front-end processing is carried out in such a way that interference signal content including shield interference is extracted without extracting tag signal content in the received signals over a period of time. In this way, the first and second transmitter antennas of the system can be driven with drive signals having a phase difference of other than 0° or 180° and the tag evaluation processing can be carried out during the entire period of the drive signals.

Title: Fluid check valve with replaceable valve seat and flapper assembly
Inventor: MUDDIMAN ROBERT W
IPC: F16K15/03
Filed: 1993-12-09
Granted: 1999-11-30
Abstract: A fluid check valve of the two flapper variety which has replaceable seat flapper assembly. The assembly comprises a tubular ring having a seating area on the surface of one end and a reduced diameter portion on the other end. A pair of pin keepers are attached to opposite sides of the seat ring and the flappers are pivotably attached to a pin that passes through holes in the keepers. Preferably the pivot holes in the keepers or the pivot holes in the flappers or both are elongated to allow movement of the flappers along the valve axis. The seat ring is a sliding fit in the bore of the valve body and abuts against an annular rib in the valve body bore.      The reduced diameter portion of the seat ring extends through the annular rib. A retaining ring is attached to the reduced diameter portion by threaded engagement, bolts, or other means and tightened until it abuts against the other side of the annular rib thus holding the seat ring in tight assembly in the valve bore against the rib.

Title: Method and apparatus for treating an ophthalmic lens mold
Inventor: ADAMS JONATHAN PATRICK
IPC: B29C59/12
Filed: 1993-12-17
Granted: 2005-03-01
Abstract: An apparatus and method for directing accelerated electrons to at least part of one surface of one ophthalmic mold piece prior to filling with monomer and lens polymerization. In particular it has been found that generation of the ionized oxygen by means of a corona treatment electrode sufficiently increases the adherence of the polymer to the mold piece so treated. Tn the preferred embodiment, the flange around the convex, male piece of the lens mold is corona treated so that when the mold pieces are separated after lens polymerization, the flashing of excess polymerized material surrounding the lens cavity adheres to that male, convex piece flange while the lens is removed with the female, concave piece.

Abstract: Two LNG storage tanks receive LNG from a fill station.     The two storage tanks are connected to an overflow tank into which the LNG flows during pressurization of the system. The overflow tank is connected to the use device, i.e. the vehicle's engine, through a heat exchanger to provide high pressure natural gas thereto. The fill station initially delivers LNG to the two storage tanks until the-tanks are substantially filled with LNG whereupon the fill station automatically stops delivery of LNG and begins to deliver natural gas vapor to the storage tanks until the pressure in 'the system reaches a predetermined maximum that is equal to or greater than the pressure required by the use device. During the pressurization of 'the system some of the LNG in the two storage tanks is forced into the overflow tank by the incoming natural gas vapor.

Abstract: A prosthetic device for sustaining a vessel or hollow organ lumen (a stent) has a tubular wire frame (1) with rows of elongate cells (2) having a larger axis and a smaller axis. The cells are arranged with the larger axis in the circumferential direction of the frame (2) and the smaller axis parallel to the axial direction thereof.  Each cell is formed by two U-shaped wire sections, and in a plane perpendicular to the longitudinal axis one of the branches of the U-shaped wire sections in one row form together a closed ring-shape (4) which provides the frame (1) with large radial stiffness. In the axial direction the frame (1) has only low stiffness so that it easily conforms to the vascular wall even if this deforms due to external loads.

Title: Apparatus and method for forming coreless paper roll products
Inventor: MOODY JOHN R
IPC: B65H18/28
Filed: 1995-03-06
Granted: 2004-08-03
Abstract: Coreless paper roll products are formed by slitting a paper web to form web segments having side edges. The web segments are then wound about an elongated winder shaft.  During winding of the paper web, liquid is applied to the web segments only at the side edges thereof while maintaining the web segments free of liquid between the side edges. A  rider roll that has liquid applied thereto by sponges or spray nozzles may apply liquid to the side edges of the web segments. When the rolls are formed and stripped from the winder shaft, the openings located at the ends of the roll at the roll central aperture will be well defined and allow ready insertion of a dispenser spindle. All the material of the roll can then be dispensed.

Abstract: A method and apparatus for delivering multimedia video data from a server (host processor) to a plurality of clients connected to a communications network.  More specifically, with this invention, preprocessed video and multimedia data packets are stored in switches of the network. When a client desires to receive the video and multimedia data, sends a request to the host processor which in turn sends a control message to the switches storing the requested data. These switches in turn send the requested data to the requesting client. If the data is not stored in the switches, the data must then be forwarded directly from the server to the requesting client.

Abstract: Adaptive apparatus for eliminating interference from a received signal provided on a transmission line caused by radio transceivers includes a plurality of frequency tunable filters tuned to the operating frequency of a corresponding transmitter.  The transmitter signal of each transmitter is provided to a corresponding filter.          The filter eliminates the non-essential transmission of harmonics, intermodulation and wideband noise of the transmission signal.   The adaptive apparatus includes a plurality of cancellation devices wherein each cancellation device receives a sample of each filtered transmission signal and the received signal.  The received signal includes an error portion generated by the transmitters and a non-error portion corresponding to the signal received by the antenna.  Each cancellation device compares the corresponding sampled transmission signal with the sample of the received signal.  A cancellation signal is generated by the cancellation device that is substantially equal to and opposite in phase to the error portion of the receive signal.  The cancellation signals are then combined and amplitude and phase adjusted so that they have substantially the same amplitude but are 180° out of phase with the error portion.  The combined error signal is injected onto the transmission line and provided to each of the frequency tunable filters.

Abstract: Multi-sensor correlation apparatus and methods for flash correlating data derived from a radar and a radar warning receiver to more accurately determine the direction to a threat radar that emits a reflection beam in the same direction as its transmit beam. Data association is performed by comparing the intercept timing of the main transmission lobe of the threat radar as observed by the radar warning receiver with the intercept timing of the main reflection lobe of the threat radar observed by the radar. The radar apparatus comprises the radar for detecting the reflection beam, and the radar warning receiver for simultaneously detecting the transmit beam. A flash correlator detects the time coincidence of the two detection events and correlates radar data generated by the radar and radar warning receiver using the time coincidence detection. More specifically, the radar is caused to look for a range Doppler cell that consistently jumps in magnitude at the same time the radar warning receiver detects the transmission main lobe intercept of the threat radar. Thus the radar is cued to look for a reflection lobe at the same time the radar warning receiver detects a transmission lobe.
