Title: Electrochemical fuel cell employing ambient air as the oxidant and coolant
Inventor: FLETCHER NICHOLAS J
IPC: H01M8/24
Filed: 1994-12-07
Granted: 1999-01-05
Abstract: An electrochemical fuel cell assembly includes a membrane electrode assembly which comprises an anode, a cathode having a surface thereof exposed to ambient air, and an ion exchange membrane interposed between the anode and the cathode. A seal forms a gas-impermeable barrier around the anode to which a gaseous fuel stream is supplied. The assembly further includes a thermally conductive plate having a plurality of thermally conductive members of fins extending from a major surface of the plate. The thermally conductive members contact portions of the exposed cathode surface. Adjacent thermally conductive members cooperate with the plate and the exposed cathode surface to form air conducting channels. Heat generated exothermically in the membrane electrode assembly is dissipated to the atmosphere through the thermally conductive members.

Abstract: A system having two or more A.C. motors driving the same load. The stator windings and rotors of both motors each conduct current having a vector representative of a magnitude and angular position of the current in the respective rotor and stator winding. Stator current sensors are provided for producing an indication of the magnitude of the stator current vector to each motor. Encoders are provided for sensing the rotating speed of each of the rotors from which can be calculated the angular position of the rotor load current vector with respect to the rotating stator flux current vector. A first torque control controls the magnitude of the stator current of a first one of the motors such that the stator flux current vector of the first motor and the rotor load current vector of the first motor are angularly separated by 90°. This angular relationship produces maximum torque at the rotating speed of the first motor. A second torque control receives an indication of the magnitude of the torque of the first motor from the first torque control. Using this information, the second torque control controls the magnitude of the current of the stator of the second motor such that the angular position of the stator flux current and rotor load current vector of the second motor have a 90° separation so that the second motor produces substantially the same magnitude of torque as the first motor.

Abstract: A method and apparatus are described for reducing, in communication signals received by a local network from a remote network (FAR-IN signals), thatenergy content that is attributable to echoes of signals transmitted into the local network (NEAR-IN signals). This is achieved, in part, by generating a time-varying TEMPLATE signal which represents the smoothed energy content of NEAR-IN signals delayed according to the echo path and attenuated by an estimated echo transmission loss. A non-linear processor passes the FAR-IN signal substantiallywithout attenuation if it exceeds the TEMPLATE, but attenuates the FAR-IN signalif it lies within a defined range below the TEMPLATE.

Filed: 1997-04-10
Granted: 2001-02-13
Abstract: A vibrator motor for electric hair clippers, massagers and the like includes a fixed magnetically permeable piece and a moving magnetically permeable piece. The fixed and moving pieces form a plurality of flux gap zones between selected corresponding surfaces of the fixed and moving pieces. Each of the flux gap zones has an air gap formed between the selected corresponding surfaces of the fixed piece and the moving piece. The air gaps have a total gap surface area, and an apparent gap surface area. The apparent gap surface area can be measured by viewing a selected surface which forms each gap through a plane which is generally perpendicular to the direction of the path of oscillating motion of the moving piece, or through a selected cross-section of the fixed or moving piece which is perpendicular to the path. In this invention, the total gap surface area of the gap in at least one of the flux gap zones is greater than the apparent gap surface area of that gap or gaps.
