Inventor: MUELLER ALWIN
IPC: H01M8/24
Filed: 2005-10-28
Abstract: A cooling plate module for fuel cell stacks is provided, comprising an anode-side terminal plate and a cathode-side terminal plate, whose mutually facing surfaces as cooling surfaces tightly enclose a coolant distribution structure and are joined to one another by means of a bonding agent. According to the invention the bonding agent is applied to the cooling surfaces exclusively outside the coolant distribution structure surrounded by a seal, so that the bonding agent and coolant do not contact one another. Since the current transport between the terminal plates takes place principally via contact elements arranged in the coolant structure, it is not necessary for the bonding agent to be electrically conducting.

Patent CA-2535158-A1 (CA)
Title: Flow sensor and fire detection system utilizing same
Inventor: SHACHAR YOSI
IPC: G01F1/688
Filed: 2006-02-03
Abstract: In a fire sprinkler system, flow sensors are used having strain gauges mounted on supports which project into the sprinkler pipes. When water flow occurs, the supports bend, changing the strain gauge resistance and producing a signal which can be analyzed to indicate which sprinkler heads are open. Since there are no mechanical switches, the sensor units are much smaller and cheaper than previously, and provide more information. A strain gauge can also or alternatively be located outside the pipe to detect vibration caused by flowing water. As an alternative to strain gauges, piezo film can be used, with a vibration analyzer to analyze the signal from the film to determine whether water flow is occurring and which sprinkler heads are open. A piezo film can also be placed on the pipe exterior and the signals from the two piezo films can be applied to differential inputs of a differential amplifier, to cancel signals caused by external influences such as pipe vibration. A thermistor can also be used to sense water flow, using temperature changes when the water begins to flow.

Abstract: A front-loading, refuse collecting vehicle is modularly provided with a combination of a low-profile, front-loadable waste bin (intermediate container) and one or more, side-loading robotic arms. To reduce mechanical stresses along couplings between the vehicle and the combination of the intermediate container and the robotic arm(s), a major portion of the mass o f the robotic arm mechanism is situated to the rear of the intermediate container so that a mass and beam combination is defined where the mass- supporting beam has reduced length. More specifically, hydraulic and/or othe r relatively massive motor means of the robotic arm mechanism are mounted to t he rear of a refuse-containing wall of the intermediate container. Elastomeric and/or other dampening means may be interposed between the vehicle and the bulk mass of the combination of the intermediate container and robotic arm mechanism for converting into heat some of the vibrational energy which may otherwise move between the vehicle and the combination of the intermediate container and robotic arm mechanism. A modular sled system may be provided f or supporting different robotic arms in combination with refuse containers made of different materials as may be appropriate for different waste collection situations.
