  • Patent number: 5234084
    Abstract: An improved piston compression valve mechanism for a shock absorber includes a seal carrier member carried by the shock absorber piston and having a radially extending flange portion and a downwardly extending cylindrical portion, an o-ring seal mounted between upper and lower radially extending arms on the flange portion, and a coil spring mounted on the piston above the seal carrier member. The lower arm of the flange portion has an inner downwardly facing surface adapted to engage an upwardly facing valve seat on the piston, and the upper arm of the flange portion has an upwardly facing surface in force transmitting contact with the lower end of the coil spring. The cylindrical portion of the seal carrier member is provided with a plurality of flow openings spaced about its circumference and along its axial length which are normally in a closed position against the piston.

  • Patent number: 5122925
    Abstract: Package for electronic components of a switch, which switch includes sensing components such as thermistor, measuring components, and output-control components, some of which components are relatively highly power-dissipative. A first portion of the switch supports the thermistor in a bushing wherein the head of the thermistor is bonded to the bushing with an electrically insulating material and the head of the thermistor is bonded to a wall of the package with a thermally conductive material, all of which bonding provides shock and vibration protection for the thermistor. Heat is removed from the highly power-dissipative components by a thermally conductive material which conducts heat from the components to a surrounding capsule and by wires which connect the switch to outside circuit components.

  • Patent number: 5097470
    Abstract: A diagnostic system coupled to a programmable logic controller (PLC) via a serial data link monitors the operation of apparatus under the control of the PLC. Upon detection of a first event-initiating signal, a central processor unit (CPU) in the diagnostic system initiates a timer. The CPU then awaits receipt of a second confirming action signal representing completion of the event initiated by the first signal. The timer times out after a predetermined time interval determined by an operation parameter of the controlled apparatus. If the second confirming action signal is not received before the timer times out, the CPU provides an alarm signal to a video display such as a cathode ray tube (CRT) for displaying an alarm message.

  • Patent number: 5054385
    Abstract: The improved milk pasteurizing control apparatus is of the type having a flow diversion valve controller in an enclosure with a door, panel or the like required to be sealed on the outside of the enclosure by a regulatory official. Such seal is applied only after the official is satisfied that the controller and its control routine is operating properly. The improvement includes a controller with a computer chip for executing a control routine programmed in the chip. A barrier, overlay or other obstructing technique within the enclosure "blocks" access to the chip program and prevents alteration of the routine. If the exterior seal is broken (to perform certain types of maintenance, for example), the door may be re-sealed by the official without again testing the entire control routine.

  • Patent number: 4941479
    Abstract: A protecting and restraining apparatus for use in applying an intravenous or catheter system to an extremity of the body for substantially immobilizing the extremity while permitting continued intravenous or catheter system operation comprising: an elongated flexible sheet member adapted to be wrapped about and encompass the arm, the sheet member further comprising a main base portion and a plurality of straps integrally formed with and transversely depending from the main base portion at a marginal longitudinal edge of the main base portion, each of the straps being connected to its adjacent straps at selective points along confronting marginal transverse edges of the adjacent straps; a flexible sleeve member being pivotally attached to a first surface of the sheet member coextensively along one marginal longitudinal edge of the sleeve member so as to allow pivoting of the sleeve member toward and away from the first surface of the sheet member, the sleeve being adapted to accept and retain a stiffener membe

  • Patent number: 4907160
    Abstract: An intersection monitor for remote monitoring of traffic intersection controllers. A central computer is connected through the public telephone system to intersection monitors, one of which is located at each remote intersection. The remote intersection monitor monitors the operation of the intersection controllers and related equipment and, upon detecting the malfuntions of a preselected priority, report such malfunctions by placing calls through the public telephone system to the central computer. The central computer, by placing a call on the telephone system, also may interrogate each of the remote intersection monitors and transfer operating instructions to each monitor. Vehicle and pedestrian detectors also are monitored by each remote intersection monitor and unusual activity or inactivity of such detectors is reported by the remote intersection monitor to the central computer.

  • Patent number: 4814765
    Abstract: The status of the traffic signals is repeatedly monitored. A visual display is presented of the spatial arrangement of the traffic signals in the system. The currently monitored status of the traffic signals is repeatedly represented on the display, spatially coordinated with the display of the respective traffic signals. A plurality of previously monitored statuses is also repeatedly represented on the display, spatially coordinated with the respective traffic signals and a traffic speed progression representation therebetween. The display distinguishes between through green and local green traffic signal status. A comparison is made of the currently monitored status of a traffic signal under consideration with the previously monitored status of the adjacent traffic signals as the latter arrives at the traffic signal under consideration and a separately distinguishable mark represents a discrepancy in the comparison when the previously monitored status is through green.

  • Patent number: 4655278
    Abstract: A method and apparatus are disclosed for simultaneously regulating the temperature of interior air, and ventilating the interior air with air from outside by means of passing said interior air through an interior heat exchanger, simultaneously passing outside air through an outside heat exchanger, extracting a portion of the inside air, and directing it to the outside air for venting outside, simultaneously extracting a portion of the outside air and venting it to the inside air, continuously passing a heat exchange medium into one of the heat exchangers, and transferring the heat exchange medium from one heat exchanger to the other heat exchanger, via an expansion device to procure transfer of heat from one heat exchanger to the other, and passing the heat exchange medium through flow controls, responsive to temperature of the inside air, to selectively direct flow of medium either to one of the heat exchangers or to the other. Also disclosed is a method of regulating temperature by means of the system.

  • Patent number: 4509585
    Abstract: The supply of energy in response to thermostat demand, to heating and cooling equipment is reduced by intermittent interruption during demand intervals and prolonged intermittently upon cessation of demand in accordance with the duration of such demand intervals pursuant to memory stored heating and cooling sequences of power interruption cycles. Sensors detect the presence and absence of energy demand to time the duration of the demand intervals and control the intermittent interruption in the supply of energy for energy saving purposes.

  • Patent number: 4510549
    Abstract: A power supply particularly for use with a traffic control system has a voltage monitoring and control system which continually monitors the line voltage fed to the traffic control system and automatically turns off the power when the voltage drops below a predetermined minimum for a predetermined time period or provides a warning signal should the voltage drop below a higher second predetermined minimum for a predetermined time interval. In the event that the voltage returns to a predetermined acceptable value for a predetermined time period, the power is automatically restored and the warning signal discontinued. The monitoring system includes sensors operative in response to each of the control parameters which operate in conjunction with logical control circuitry to effect the desired controls.
