Patent CA-2281406-A1 (CA)
Inventor: NAPIORKOWSKI JOHN J
IPC: H02H7/20
Filed: 1999-09-02
Abstract: An excess voltage protector for protecting telecommunication equipment from surges on transmission lines utilizes a solid state electronic device. The electronic device conducts when it reaches a threshold voltage potential. The device is connected in a path between two ground nodes of a bridge circuit. The bridge circuit is made up of diodes. The diodes are oriented to steer excess voltage on tip and/or ring lines through the solid state device to ground. An additional diode is connected into the path between the two diodes in series with the solid state device. The additional diode brings the effective capacitance of the solid state device down, enabling the protector circuit to be utilized in higher frequency transmission lines.

Inventor: MEHTA ANIL N
IPC: A47J39/02
Filed: 1998-03-26
Abstract: An electric chafer heater for a chafer (10) is disclosed herein. The chafer heater (36, 38) is removably supported by a shelf disposed below a chafing dish. The chafer heater includes a base having a cylindrical bottom portion (52) held within an aperture in the shelf (14) sized for receiving a standard can heater. The chafer heater further includes a resilient member extending upward from the base, and an electric heating assembly coupled to the resilient member opposite the base.  The heating assembly has a heating surface posititionable above the base by the compression of the resilient member. The heating surface is biased against the chafing dish when the base is supported by the shelf to provide a thermal interface to transfer heat between the heating surface and the chafing dish. The heating assembly has variable (e.g., low and high) power settings selected by an input device (e.g., a switch). The heater includes a ballast at the bottom of the base, and a switch which cuts off the flow of electricity to the heating assembly in response to a sensed parameter (e.g., temperature; inclination). A  visual indicator may provide an indication when the heating surface exceeds a predetermined temperature.

Abstract: A vacuum waste system having reduced noise levels associated therewith. The vacuum waste system includes a sanitary unit for initially receiving waste. An intermediate container is connected to the sanitary unit by a first sewer pipe and a first sewer valve. A receptacle is connected to the intermediate container by a second sewer pipe and a second sewer valve. The system also includes means for generating vacuum in the second sewer pipe, intermediate container, and first sewer pipe. Transfer of waste from the sanitary unit to the receptacle is performed in two stages. In a first stage, the first valve is opened and the second valve is closed so that vacuum transports the waste from the sanitary unit to the intermediate container. In the second stage, the first valve is closed and the second valve is opened to transfer the waste from the intermediate container through the second sewer pipe. Means are provided for adjusting the volume of the intermediate container to control the velocity of air entering through the first valve, thereby reducing noise. The volume adjusting means increase the volume of the intermediate container during the first stage so that the intermediate container holds a sufficient amount of air at approximately ambient air pressure to perform the second stage.

Abstract: An improved apparatus and method for conducting Induced Polarization surveys for polarizeable material located in the subsurface. This apparatus and method provides results that are free of the influence of electromagnetic coupling. The apparatus consists of a direct current generator and electrodes that inject a steady direct current into the same volume of earth to which a standard Induced Polarization system is being applied. This direct current perturbs the electrochemical processes that are the cause of the Induced Polarization phenomenon and thereby causes a change of the output of the standard Induced Polarization system that can only be caused by a change in the Induced Polarization effects because a direct current can not cause any change in the electromagnetic effects that are an inherent part of the data provided by any Induced Polarization survey. In any survey which is performed with the invention the recorded dat is the change of the Induced Polarization and Resistivity readings when the biasing current is switched on. This perturbation of the Induced Polarization effect also leads to changes of the measured DC Resistivity of any survey site that contains polarizeable material. This change in the Resistivity permits the presence of polarizeable material to be recognized in Direct Current conditions.

Abstract: Method and transmission system for the signalling of a carrier frequency The present invention provides a possible way of signalling digitally a carrier frequency which is used at a predetermined instant after the signalling. The invention can be used in particular in a so-called multiframe mode of a mobile part (2) of a digital transmission system, in a multiframe mode the mobile station (2) receiving data from a fixed station (1) only during so-called multiframe frames in order to be able to resynchronized with the fixed station (1) in an energy-saving manner. A multiframe frame is in this case provided after every (m-1) frames of the transmission. The carrier frequency (fx) used by the fixed station (1) in the next multiframe frame is in this case signalled to the mobile station (2) by means of the bits which correspond to bits of the header of the A field of the DECT standard.      According to the invention, as a result of the initially effected signalling and synchronization of the carrier frequencies (fx) of the multiframe frames as the first step, it is then possible for the carrier frequency synchronization with regard to the frames between two successive multiframe frames to be carried out.

Title: Cavitated insulating support base for hot water tank
Inventor: LESAGE CLAUDE
IPC: F24H1/18
Filed: 2000-03-10
Abstract: A hot water tank is comprised of a cylindrical disc-shaped support base on which is supported a cylindrical inner tank concentrically therewith. A circumferential ridge projects upwardly adjacent an outer peripheral edge of the support base and spaced from a lower edge portion of a circumferential side wall of the inner tank to form a circumferential containment channel between the ridge and the lower edge portion. The channel has a volume sufficient to receive a lower portion of a plastic film pouch wrapper disposed at least about a lower section of the inner casing as well as a pre-determined quantity of hot expandable liquid urethane placed therein in sufficient quantity to fill a space between the inner casing and an outer shell secured spaced about the inner casing when the urethane is expanded. The channel prevents the liquid urethane from flowing out of the lower portion of the wrapper located therein due to deterioration of the wrapper when exposed to the hot liquid urethane.

Abstract: Traffic management or enforcement is performed through the use of a monitor transponder in the environs of an RF highway toll collection system. When normally operating transponders communicate with a roadside reader system, the roadside system communicates with the monitor transponder, which in turn signals if a valid normal transponder is detected. If no signal is generated by the monitor transponder, it is evident that the vehicle has no transponder or that the transponder is faulty or invalid.

Abstract: La présente invention concerne une structure d'électrode annulaire de dimension radiale verticale. Cette électrode fait saillie depuis le diamètre extérieur du cathéter lorsqu'est montée dessus. L'électrode annulaire verticale est pourvue d'une surface de contact tissulaire qui, en général, touche les tissus d'un patient avant que le cathéter ne vienne en contact avec eux. Cette structure permet à chaque électrode montée sur l'extrémité distale du cathéter d'avoir un bon contact uniforme avec les tissus. Elle permet également que soit appliquée une plus grande pression sur ces tissus, avec cependant une force réduite en comparaison avec une configuration de cathéter-électrode classique, et ceci en raison de la zone de contact diminuée que présente l'électrode annulaire verticale. Dans une configuration préférée, l'électrode verticale est pourvue de bords courbés et réguliers pour éviter d'abîmer les tissus lorsque le cathéter est introduit ou retiré du corps du patient.
