摘要： A pressure sensor comprising a pressure-displacement translating mechanism including a movable body driven by a hydraulic pressure and a spring for urging the movable body in a direction opposite the pressure, and a displacement-pulse phase conversion unit including a permanent magnet secured to the movable body and a magnetically soft member carrying an electrical coil thereon and disposed at a stationary point adjacent to the region of movement of the permanent magnet. A pulse voltage is applied to one end of the electrical coil, the other end of which is connected in series with a resistor. A voltage drop across the resistor is detected, and a time lag of the voltage drop with respect to the pulse voltage, representing a measure of hydraulic pressure, is provided in the form of an analog voltage or a digital code.

摘要： A sensor device senses the presence or absence of pressure. As the pressure about the device exceeds a pre-established level, a movable tip of the device is depressed. A thermally conductive portion of the tip thereby engages a spaced apart portion of an element. This engagement upsets the thermal properties within the device, causing two heat responsive members to disengage. A sensing apparatus is also disclosed which includes the above described device and an electrical circuit which comprises a potential source and a current indicating means. When the above mentioned heat responsive members are engaged, current in the circuit is at a sufficient level to activate the current indicating means. However, when the heat responsive members disengage, the current must pass through a resistive material, thereby lowering the level of current flow. This lower electrical current is then not sufficient to actuate the indicating means.
摘要翻译：传感器装置检测是否存在压力。当装置周围的压力超过预先设定的水平时，该装置的可动尖端被压下。尖端的导热部分因此接合元件的间隔开的部分。该接合使设备内的热性能变差，导致两个热响应构件脱离。还公开了一种感测装置，其包括上述装置和包括电位源和电流指示装置的电路。当上述热响应构件接合时，电路中的电流处于足够的水平以激活电流指示装置。然而，当热响应构件脱离时，电流必须通过电阻材料，从而降低电流的水平。这种较低的电流然后不足以致动指示装置。

摘要： A temperature-compensated gas density relay includes a bellows unit subjected to the gas, the pressure from which is transmitted by the bellows unit through a support mounting a bi-metallic disc and a shaft carried by the central portion of the bi-metallic, and longitudinal displacement of the shaft in response to the change in gas pressure serves to actuate the contacts of an electrical switch component of the relay. Should there be a change in the gas temperature, compensation therefor is accomplished by a temperature-induced displacement of the central portion of the bi-metallic disc, and hence also the shaft, in a direction opposite to that caused by the change in the gas pressure resulting from that same change in temperature.

摘要： A sealed hollow capsule having inner and outer ends and a side wall contains a pair of electric contacts spaced lengthwise of the capsule, the outer end of which supports one of the contacts. The side wall has an annular groove in it reducing the thickness at that point to a thin band that is compressible to reduce its width when a predetermined pressure is exerted against the outer end of the capsule so that one contact will engage the other contact. The switch is especially suitable for closing an electric circuit connected with electrical firing means in an explosively actuated cable cutter.

摘要： A safety cutoff device mounted on a pressure tank between the tank and the pressure activated pump switch for automatically locking the switch open upon the reduction of air in the tank to the point at which damage could result to the pump electrical system should the pump be allowed to continue to operate. The safety cutoff includes a float valve which is activated to segregate a pressure accommodating auxiliary tank in direct communication with the switch from the pressure tank upon the reduction of air and elevation of water level in the pressure tank to a predetermined point. The air, under pressure, locked within the auxiliary tank in turn locks the switch open and in effect deactivates the entire system until reset.

摘要： A heating-cooling thermostat employs alternative circuits during heating and cooling seasons to move an actuator in one direction. Heaters controlled by thermostatic contacts in each of the alternative circuits heat bimetals to open the contacts periodically to provide pulsed on-off current through the actuator. The on-off time ratio is modified by the deviation of the controlled temperature from a setpoint to provide on-off time proportioned current to the actuator.

摘要： A flexible diaphragm-type pressure switch sensitive to light pressures on the order of 7 ounces to 11 ounces for use in freezing, moist atmospheres containing plant particles such as husks, cracked seeds and leaves which are likely to cake and freeze on the diaphragm, thus rendering the diaphragm insensitive to its designed pressures. A thermostatically controlled heating element is incorporated in the switch without changing the external dimensions of the switch, the heating element preventing freezing of moisture on the diaphragm and drying the plant particles accumulated thereon so that they can be carried away by air currents.

摘要： A warning switch is disclosed for continuously actuating an alarm device in response to a momentary fluid pressure unbalance in a dual hydraulic brake system. A piston is slidably disposed in the switch housing for movement in response to a fluid pressure unbalance. A switch contact unit having an insulated terminal and an insulated contact stud is detachably mounted on the switch housing. When the piston is momentarily displaced in response to a momentary fluid pressure unbalance, the terminal is grounded through the contact stud and through the piston to momentarily actuate the alarm device. A latching relay means is disposed within the switch contact unit housing and provides a continuous ground for the terminal in response to the momentary ground provided through the piston. In a first embodiment, the alarm device and the latching relay circuit are arranged in series, and a prove-out switch for testing the alarm device is interposed between the alarm device and the latching relay circuit. In a second embodiment and a third embodiment, the latching relay circuit is arranged in parallel with the alarm device, and an isolation means prevents actuation of the latching relay by the prove-out switch. In the second embodiment this isolation means includes a double pole latching relay, and in the third embodiment this isolation means includes a diode.
