摘要： A unit ventilator system includes a number of special diaphragm valves, each of which has a pair of chambers separated by a common diaphragm with a control passage interconnecting the chambers. A spring loaded valve operatively opens and closes an inlet passageway to one chamber. As an on-off valve, the control passageway is connected to the output passageway downstream of an orifice. The second chamber has a sealing wall engaged by the valve to reduce the effective area, so the incoming pressure must decrease below the opening pressure. An exhaust passageway extends from the second chamber sealing wall. A second valve apparatus has a second valve in the control passageway, with a mechanical actuator engaged after the diaphragm has moved a selected amount. The diaphragm unit moves with pressure increase until the second valve opens to transmit the pressure through the first chambers to the outlet. A regulating zero differential diaphragm pressure relief valve apparatus includes the inlet passageway normally closed by a valve unit. The first chamber is connected to an exhaust and by the control passageway to the second chamber to dampen the movement of the valve disc and in particular eliminates the chatter associated with the Bernoulli effect.

摘要： An audio-communication system includes a single pair of connecting lines between a master station and a plurality of remote stations. Each station includes a locally powered differential amplifier having a high input impedance and a low output impedance. Switches connect a microphone or a speaker to the amplifier and the lines. The master station includes a D.C. signal source connected to the lines and the remote stations include line reversal circuits responsive to a DC signal to establish a listen condition such that the remote station provides hand-free communication. A line discharge circuit is connected to the lines at the master station and automatically discharges line capacitance when the listen mode is set at the master station.

摘要： A Doppler motion frequency signal is generated by the movement of an intruder in a radio frequency energy field. The signal is to establish a series of related pulses which are simultaneously applied to all clock inputs of a shift register and to a timer. An alarm signal line is connected to any one of the shift register outputs and a reset signal line is connected from the next output. The timer preferably employs a programmable unijunction transistor and a predetermined time after a last pulse occurs generates a reset pulse to reset the shift register and initiate a new counting cycle. A predetermined number of cycles must occur within a predetermined time which is less than the normal timing cycle of the timer in order to prevent the timer from triggering and resetting the counting device.

摘要： A bi-material sensing element is essentially rigidly mounted about the periphery. The element is mounted in an environment to sense the humidity, temperature or the like and is to provide a detectable movement normal to the plane of the element. Holes or slots of a predetermined shape are formed in the element and are equicircumferentially distributed about the center. At a critical diameter, the unit has zero sensitivity. The sensitivity of the element will increase when the holes are moved to either side of the critical diameter, with the deflection in opposite directions as the holes are located to opposite sides of the critical diameter. The sensitivity also increases with increased ratio of voids to solid material along the circle diameter on which the holes are located. The critical diameter location varies with the several factors involved in the construction of the bi-material disc.

摘要： A wide range and high resolution potentiometer is provided by using a plurality of variable resistor pairs and a base potentiometer. The pairs are connected together in two complementary series chains on either side of the base potentiometer. A slide means is connected to each pair in a ganged relation to selectively vary their resistance in equal but opposite direction so that the total input resistance of the potentiometer always remains constant. Each pair added multiplies the basic resolution of the potentiometer.

摘要： A hydraulic actuator is constructed in an enclosed housing having an internal wall member which divides its interior into forward and rear chambers. An elongated actuator element is slidably supported in the forward chamber with its forward nose portion extending outwardly through an opening in the wall of the housing. A piston is transversely supported on the rear end portion of the actuator element and is in slidable sealing engagement with a cylindrical wall contained within the forward chamber to define an expandable chamber with this cylindrical wall and the internal wall member. A spring means constantly urges the piston towards the internal wall member. Pump means contained in the rear chamber introduces a fluid under pressure through a passageway formed through the internal wall member into the expandable chamber to force the piston and associated actuator element outwardly of the housing to an extended position. The relative location of the actuator element is detected by a position sensing means which provides a variable control signal in response to the movement of the actuator element for energizing the pump means.

摘要： A diaphragm element includes thin outer conducting layers integrally bonded to the opposite sides of a core layer of silicone or other dielectric which is a resilient, flexible material, to form a single, integral, resilient, flexible structure. The conducting layers are a matrix of the material of the dielectric core layer with carbon or like conductive particles embedded therein. One conducting layer is spaced peripherally from the edge of the core layer to thereby prevent electrical contact between the two conducting layers. The total unit is rigidly mounted about the peripheral edge with metallic contacts connected to the conducting layers as by a silver conducting paint applied to the outer surface of the layers. The element will thus flex to the side of the lower pressure with a change in the effective conducting area of the opposite conducting layers and a simultaneous decrease in the thickness of the dielectric inner core. Consequently, the capacitance of the unit varies as a function of the deflection and thereby in accordance with the pressure differential applied across the diaphragm element.

摘要： The disclosure of this invention describes a gas valve having an on - off control valve and a modulator valve which will modulate the gas flow from high fire to low fire over a predetermined temperature throttling range. The on - off control valve and modulator valve are mounted on top of a central body having a main gas passageway interconnecting its inlet and outlet. A main valve is used to open and close a main port formed within the gas passageway and a pressure diaphragm, which forms one wall of a closed chamber, is operably connected to this main valve such that increases in pressure within the chamber tend to open the main gas port. The on - off control valve includes a two-position valve means for providing the opening and closing of a second port disposed in a bypass passageway extending between the inlet and closed chamber. A remote thermostat provides actuating signals for energizing or deenergizing the on - off control valve to reposition the two-position valve means. A modulating valve means is used to open and close a third port formed in a passageway between the closed chamber and outlet, and a temperature responsive means operates the modulating valve means in response to temperature variation sensed at a local point. The temperature responsive means includes an output member movable in response to temperature variations of the environment surrounding the temperature sensing means and also includes a signal actuating means. This signal actuating means provides actuating signals to energize and deenergize the on - off control valve in response to temperature changes about the local temperature sensing means.
