| 9 | Temperature dependent electronic control switch | US922731 | 1978-07-07 | US4240580A | 1980-12-23 | Werner Fehr |
| A temperature dependent electronic control switch, especially suited for an automatic temperature control in vehicles, including one or more NTC resistors as sensors in a bridge circuit, an amplifier, to amplify the signals from the sensors, a solenoid for producing a variable magnetic field from signals received by the amplifier, an iron strip, an air nozzle connected to a vacuum, a servomotor connected between the air nozzle and the vacuum, and a control flap.

| 10 | Variable-gradient spring sub-assembly | US779511 | 1977-03-21 | US4112960A | 1978-09-12 | Henry M. Hermanns |
| A range spring sub-assembly providing a variable gradient with minimum hysteresis for the feedback assembly of a pneumatic transmitter. The sub-assembly is constituted by a helical spring whose lower end is secured to the pivoted feedback arm of the feedback assembly and whose upper end is coupled by a span adjustment screw to a fixed arm thereof. The arm porton of the screw extending above the fixed arm is engaged by a zero adjustment knob which rests on top of the fixed arm, whereby when the knob is turned, the screw is axially shifted to vary the tension of the spring coupled thereto. The span adjustment screw has a coupling terminal head that is received within the upper end of the spring and is provided with a set of outwardly projecting pins. The pins are at different heights and are interposed between adjacent convolutions of the spring whereby the pinned convolutions are rendered inactive and the convolutions therebelow remain active. By rotating the screw, the number of active convolutions is varied, thereby varying the gradient of the spring. | ||||||
| 11 | Load sensing steering system with dual power source | US708657 | 1976-07-26 | US4044786A | 1977-08-30 | James K. Yip |
| A system for providing pressurized fluid to a primary load circuit and an auxiliary load circuit, the primary load circuit being of the type which provides a load pressure signal representative of the demand for fluid in the primary load circuit. The system includes first and second fluid pumps feeding first and second priority flow control valves, respectively, each of which has a primary outlet port connected to the primary load circuit and an auxiliary outlet port connected to the auxiliary load circuit. When the flow demand of the primary load circuit can be satisfied by the first pump, any excess flow available is fed by the first flow control valve to the auxiliary load circuit, and all of the flow from the second pump goes to the auxiliary circuit. If the flow demand of the primary load circuit is greater then the capacity of the first pump, all of its flow passes to the primary load circuit with none going to the auxiliary load circuit, and a novel pilot valve arrangement permits the load pressure signal from the primary load circuit to bias the second flow control valve to a position where a sufficient amount of the flow from the second pump is fed to the primary load circuit to meet the demand thereof, with the remainder of the flow going from the second flow control valve to the auxiliary load circuit. | ||||||

| A fluid control system having a fluid supply means and a fluid operated device. A branch chamber of a fluid operated relay is interconnected by a movable valve means with the exhaust chamber thereof or with the main chamber thereof in response to fluid conditions existing in the pilot chamber thereof. The fluid supply means is interconnected to the main chamber of the relay and to a fluid biasing chamber of a fluid operated pressure regulator. The fluid operated device is interconnected to the branch chamber of the relay and the pressure regulator is interconnected to the pilot chamber of the relay. A condition responsive fluid bleed device is interconnected to the biasing chamber whereby the condition responsive fluid bleed device effectively bleeds the biasing chamber of the fluid being supplied thereto from the fluid supply means in response to conditions being sensed thereby so that the pressure regulator maintains the fluid pressure in the pilot chamber in relation to the condition being sensed whereby the fluid being supplied the fluid operated device from the branch chamber is varied in relation to the conditions being sensed by the condition responsive fluid bleed device.
