| 101 | Valve for controlling two-way flow | US121829 | 1987-11-16 | US4792186A | 1988-12-20 | Gary H. Benjamin; Harry O. Jones |
| A value incorporated into apparatus for controlling rigidity of a vehicle seat includes a housing defining a bore terminating in first and second counterbore ends with a narrowed central portion therebetween. A first port through the housing opens into the central portion, while a second port opens into both counterbore portions at or near the junction with the central portion. A two-piece resilient sealing member is disposed within the bore, and has enlarged first and second ends positioned in sealing contact within the counterbore portions to seal the bore, The sealing member is also normally positioned in sealing contact with the junction areas to seal the central portion from the counterbore portions. The sealing member may be moved longitudinally within the bore to move one of the enlarged portions away from one of the junction areas to open a fluid flow path between the ports. Normally open electrical switches are provided to be actuated upon longitudinal movement of the sealing member. | ||||||
| 102 | Pushbutton vacuum-electric air control unit for automotive vehicles | US930000 | 1986-11-10 | US4720612A | 1988-01-19 | John G. Cummings |
| A series of manually depressible pushbuttons establish all of the operating functions for an automotive air control system. Latching and block-out mechanisms are provided to latch only one pushbutton at a time in the depressed position. The pushbuttons operate the first arms of spring-biased levers having second arms for selectively moving particular selector plates of a stacked set. The selector plates are adapted to operate single function control devices, including both vacuum valves and electrical switches having movable control members with knobs thereon projecting through large size and small size openings in the selector plates. The second arms of the levers extend through large size and small size slots in the selector plates. The small size slots and openings afford operating connections, while the large size slots and openings merely provide for idling movement. Each of the selector plates has a unique combination of larger and smaller slots and larger and smaller openings, whereby the depression of each pushbutton uniquely operates one or more control devices, in accordance with the functional mode assigned to such pushbutton. One of the control devices takes the form of a unique snap-action electrical switch in which the movable contactor has a combination of sliding and rocking movement. The control unit also has a non-latching pushbutton switch for causing momentary closure of a control circuit for a rear window defroster, such switch being pre-assembled as a cartridge for easy insertion into the housing of the control unit. | ||||||
| 103 | Electro-acoustical structure | US280650 | 1981-07-06 | US4395589A | 1983-07-26 | Douglas J. Williams |
| An electro-acoustical structure for switching on and supplying sound to an all-acoustical headset upon the insertion of an acoustic-use plug. A piston-valve is depressed against a spring upon the insertion of the plug, opening acoustic ports, and also moving a bifurcated contact attached to the piston to close a circuit with coactive stationary contacts for energizing an electro-acoustic transducer. | ||||||
| 104 | Ignition circuit deenergizing spring for gas appliance valve-switch | US267747 | 1981-05-28 | US4371764A | 1983-02-01 | Cleaston L. Runion |
| A turn-back spring for use with a valve-switch assembly of the type employed to control the flow of gas to the burners of a gas appliance and to energize an associated electrical ignition circuit for igniting gas flowing from the burners. The spring is mounted on the valve body of the valve-switch assembly so that one end of the spring engages a lug on the drive washer of the stem of the rotatable valve member, thereby offering increasing resistance to rotation of the valve member beyond a predetermined position corresponding to a substantially full-open position of the valve. The valve stem extends through an annular bushing which is rotatably mounted in the electrical switch of the assembly and which is effective to close the contacts of the switch when the valve member and its stem are rotated to a gas flow igniting position somewhat beyond the substantially full-open position of the valve. The spring automatically rotates the valve member back to its substantially full-open position whenever a user releases the operating knob on the outer end of the valve stem. | ||||||

| A combination of a burner valve control device and an electrical switch unit carried by the device and being operated by a movable actuator controlled by the selector of the device, the selector having a control shaft rotatable about an axis thereof. The switch unit has a snap-fit arrangement snap-fitted to the device when the entire switch unit is moved in a direction substantially transverse to the axis of the control shaft to detachably secure the switch unit to the device. | ||||||

| 107 | Potentiometer and switch control arrangement | US245237 | 1980-05-05 | US4330007A | 1982-05-18 | Edward V. Leskovec |
| A number of systems exist wherein a plurality of hydraulic motors (28a, 28b, 28c) receive pressurized fluid from a single pump (14) which is itself driven by an electric motor (12). Apparatus has been available for adjusting the power supplied to the electric motor (12), and thereby adjusting the pump (14) flow rate, in response to the operator activating one or more of the hydraulic motors (28a, 28b, 28c). However, such apparatus has generally been bulky, complicated and/or difficult to install and/or service. An improvement is provided wherein a single switch (22) is placed in either an open or closed position as an elongated member (34) placed transversely to a plurality of generally parallel rod member (20a, 20b, 20c) is rotated in response to longitudinal travel in either direction from a neutral position (32) of one of the rod member (20a, 20b, 20c). Longitudinal movement of each of the rod members (20a, 20b, 20c), controls, via a respective valve (16a, 16b, 16c), the action of the respective hydraulic motor (28a, 28b, 28c). | ||||||
| 108 | Electrical switch housing detachably mountable on a gas valve structure | US588126 | 1975-06-18 | US4002872A | 1977-01-11 | Frank B. Desio |
| An electrical switch housing which may be mounted on the control shaft of a gas valve of a household gas appliance in order to control an ignition circuit which ignites the gas that is controlled by the valve is provided. The electrical switch housing has a central aperture which holds a rotatable operating member that has an aperture in it which receives the control shaft of the valve. The switch housing may have two, three or four mounting posts which extend normal to it and are positioned relative to one another so that they prevent the housing of the switch from rotating when the control shaft is rotated. | ||||||
| 109 | Electromotive and fluid pressure force switch with maze valves | US48264474 | 1974-06-24 | US3906177A | 1975-09-16 | FIDDLER THEODORE E |
| An electromotive force and fluid pressure force controller apparatus for connecting and disconnecting the forces to devices activated and deactivated thereby in programmed conjunction with one another comprising a case having a slide chamber and at least one slide in the chamber movable between the ends of the case. Electrical contacts are located on and in the case adjacent to at least one side of the case and slide. The slide has sliding and/or snap-acting switch means aligned with the contacts for interconnecting the contacts and disconnecting them. Prongs are mounted on the case for connection to electrical supply and bussbars lead from the prongs to the contacts. The case has ports in at least one wall for transmitting fluid force into and out of the case. These ports are aligned with the travel of the slide. The slide has a channel maze valve engaging the interior of the ported wall of the case which is connected to and moves with the slide over the ports to interconnect and block communication between the ports. A flexible block having apertures aligned with the ports overlies the outside of the ported wall. Tubes lie in the apertures of the block. Clamp means surmount the flexible block and engage the case to compress the block into sealed engagement with the case, ports, and tubes to isolate each tube and its connected port from the others. Several slides may be nested in the case and individually moved and/or moved by another slide to control the forces singly or in combination. The ports, contacts, mazes, switch means, and slide are organized relative to one another and the various positions of the slide so that electrical and fluid force are connected and disconnected to the devices powered thereby as desired in the system programming.
