Inventor: GLENN CHRISTOPHER J
IPC: B60L1/00
Filed: 1993-04-28
Abstract: 2133318 9322151 PCTABScor01 A modular control means for an electrically driven vehicle in which modules (2, 12-18) are interconnected by a serial data bus (10). One line (26) of the serial data bus (10) may be biased high or low by modules of the system (2, 12-18) upon detection of a fault. This is detected by kill means (45) of the modules (2, 13-17) of the system which disables safety related functions of each module (2, 13-17), where applicable. Modules (2, 13-17) other than the remote control module (12, 18) may include wake-up means (52, 20) which supply power to the modules (2, 13-17) at start up when the data line (26) is biased high. The modules (2, 12-18) preferably operate as finite state machines with each module (2, 12-18) storing in its memory network variables required for the operation of that module (2, 12-18). The network variables including the state of other modules, external demand signals, and measured variables of the system. A method of achieving increased resolution in the control of a DC motor by a pulse width modulator having a limited number of output data bits and a method of mounting components (378) by biasing them against a wall of a casing (350) are also disclosed.

Title: Method and circuit for retuning of a radio receiver
Inventor: BUSSAN CHRISTOPHER F
IPC: H04B1/16
Filed: 1994-04-06
Abstract: METHOD AND CIRCUIT FOR RETUNING OF A RADIO RECEIVER   Abstract of the Disclosure A method and associated circuitry for retuning a tuning frequency of tuning circuitry of a radio receiver to a frequency channel of a set of frequency channels. The tuning frequency of the tuning circuitry is retuned when the tuning circuitry is initially tuned to receive a communication signal transmitted by a transmitter of a less-than-most desired network of transmitters. If a communication signal transmitted by a transmitter of a most-desired network of transmitters is detected by the radio receiver when the receiver is retuned, then the receiver camps to the transmitter of the most-desired network of transmitters.

Title: Ideal voltage controller
Inventor: RIGGIO CHRIS A
IPC: G05F1/455
Filed: 1993-05-21
Abstract: An apparatus and meth-od for controlling the voltage applied to a load is taught. The method includes receiving an AC line voltage, generating an operating AC voltage from the AC line voltage and applying this operating AC voltage ac-ross the load. A measured sig-nal which is a function of the magnitude of the operating AC voltage is generated, and then averaged to generate an average signal representative of the av-erage value of the measured sig-nal. The operating AC voltage is continually readjusted in response to changes in the average signal. The apparatus implementing this method includes terminal means for receiving an AC line voltage, means for generating an operating AC voltage from the AC line voltage, connector means for applying the operating AC voltage across the load, and voltage detection means for generating a measured signal which is a function of the magnitude of said operating AC voltage. Signal averaging means are provided for generating an aver-age signal representative of the average value of the measured signal. Finally, the apparatus includes AC voltage modulation means for adjusting the operating AC voltage in response to the average signal. In the preferred embodiment of the apparatus of the present invention, the AC voltage modulation means comprises voltage reduction means for switching off the line voltage for a portion of each cycle, the length of the portion being determined by the average value of the measured signal. The voltage mod-ulation means may comprise a phase control integrated circuit device for controlling a triac. The phase control integrated circuit device is responsive to the average signal to generate a control signal operative to control a triac to switch off transmission of the line voltage to the load for the portion of each cycle.

Title: Environmentally insensitive paper guide for strip chart recorders
Inventor: HILL DOUGLAS J
IPC: G03G15/00
Filed: 1995-03-28
Abstract: An environmentally insensitive device is described. The device uses a passive paper guide to direct an output paper stream from a paper source contained within the unit to an output aperture.  The passive paper guide uses two opposing surfaces to define a radius of curvature through which the paper strip is guided.   Use of longitudinal ridges along one or both of the surfaces reduces friction along the guide.  By providing a rotatable output cover over the aperture and using a  unit  cover,  a  printed  output  can  be  achieved  while maintaining  the  shielding  of  the  unit  from  environmental effects.

IPC: C22B21/06
Filed: 1995-08-30
Abstract: A method of gas fluxing molten aluminum with at least two, relatively small diameter upper and lower rotatable dispersers located in the molten aluminum and mounted on a shaft. Fluxing gas is added to the molten aluminum beneath each of the rotatable dispersers at a substantial rate of gas flow while rotating the dispersers at a substantial rpm in the molten aluminum. The dispersers directly shear gas bubbles that form in the molten aluminum as the fluxing gas is directed into the molten aluminum beneath each of the dispersers. The direct shearing of the gas bubbles maintains a high surface area between the bubbles and molten aluminum to effect efficient removal of impurities in the molten aluminum.
