摘要： A variable displacement lubricant pump for providing a pressurized lubricant for an internal combustion engine includes a shiftable control ring, a hydraulic control chamber which directly actuates the control ring, a pump rotor comprising a plurality of slidable vanes which rotate in the control ring, a control chamber wall, a temperature control opening arranged in the control chamber wall, and a temperature control valve which connects or disconnects the temperature control opening to an atmospheric pressure. The temperature control valve comprises a valve plunger which is axially shiftable so as to block or leave open a lubricant passage, and a first bimetal actuator sheet which directly actuates the valve plunger. The first bimetal actuator sheet comprises a first switching temperature. The valve plunger is in an open position if a lubricant temperature exceeds the first switching temperature.

摘要： An adjustable heater for aquaria, comprising a substantially tubular container (2) within which are housed an electrical heating element (3), a switch (6) comprising s fixed contacts (7, 8) and moving contacts (9, 10) and capable of electrically connecting the heating element (3) with an external source (R) of electrical power, a temperature sensor (12) with a bi-metal strip (13) capable of detecting the temperature of the liquid and interacting with the switch (6) to move it from a closed position to an open position when a predetermined temperature (T) is to reached. The moving contacts (9, 10) of the switch (6) are secured to a free end (13″) of the bi-metal strip (13) while the other end (13″) of the bi-metal strip (13) is electrically insulated. This yields the advantage that electrical current does not pass through the bi-metal strip (13) and therefore does not create a Joule effect within it which affects the sensitivity and proper behavior of the temperature Is sensor (12).

摘要： In an apparatus for the control of temperature, a continuously rotating contour disc causes a bimetallic element to execute a slow oscillating motion for alternately turning on and off a switch operatively connected to a heat generating device. The complemental lengths of one off- and one on-period which together constitute a cycle of constant duration, depend upon an arbitrary positioning of the bimetallic element (setting of the desired temperature value) and upon the temperature-responsive deformation (actual temperature value) of the bimetallic element.

摘要： 20 A multizone, heating-cooling control circuit implemented with solid-state components rather than conventional relays which heretofore have been commonly used. The control circuit is designed for use in a forced air system wherein each zone is provided with dampers and motors for controlling the positioning of the dampers in accordance with the heating or cooling demand detected by a thermostat in each of the zones. A plurality of power semiconductor devices (gate-controlled triacs) are employed to connect the windings of the zone control motors, the furnace fan, the furnace gas valve and the cooling compressor across an alternating current supply. Diode-transistor logic circuits are employed to generate the gating or control signal for the triacs in accordance with the settings of the system control switch and the temperature in one or more zones.

摘要： Control apparatus comprising a triac, serially connected to a load such as a motor, is gated through a diac. The diac conducts and turns on the triac during each half cycle of triac current when a capacitor has reached a predetermined charge through a charging resistor having a negative temperature coefficient of resistance. The NTC charging resistor gradually heats up (additional heat can also be supplied) with concomitant decrease in resistance and charge time of the capacitor so that the pulse of current seen by the motor gradually increases until a steady state condition is reached. A heating-cooling system is shown in which the above control is employed with a plurality of thermostats and a safety bypass circuit.
