摘要： A system and method is presented for a fail-safe sensor for an HVAC system. The sensor comprises a temperature detector operable to measure a temperature of a component or a medium present at the sensor, a PTC heater operable to heat the sensor to a self-regulating temperature, the heater comprising a resistive element having an electrical impedance which increases with increasing temperature in accordance with a positive temperature coefficient characteristic, and a sensor housing comprising the PTC heater and the temperature detector provided within a single housing. An algorithm is provided for HVAC systems, wherein the sensor is heated to the self-regulating temperature by the PTC heater and is then measured by the temperature detector to confirm that the temperature detector is operating properly. Further, the sensor may be allowed to cool to a temperature of the surrounding medium or the component for sensing the temperature thereof. Thereafter, by calculating the time constant of the thermal decay rate of the sensor, the presence or absence of the component or medium surrounding the sensor may be determined in a fail-safe manner by an analyzer, for example.

摘要： The present invention is directed to an oil burner system having an electric cord set coupled between a controller and a valve associated with a pump. The electric cord set is operable to activate a solenoid valve associated with the pump for delivery of fuel oil to a nozzle of the burner. The electric cord set comprises a voltage or temperature independent timer circuit operable to activate the solenoid valve a predetermined period of time after a call for ignition signal is generated by the controller, wherein the predetermined time period is substantially constant with respect to variations in line voltage or in an ambient temperature in which the oil burner system resides.

摘要： An improved system for automatically continuously replacing an engine's used lubricating oil with fresh lubricating oil throughout operation based on engine operating conditions is disclosed. The present system includes an intermittent injection control device for intermittently injecting small amounts of used lube oil into the engine's fuel system. An electronic controller is provided to vary the amount of used lube oil injected into the oil system based on the severity of engine operation. The system periodically determines an engine operating severity value, i.e. fuel consumption value, for an interval of engine operation and calculates a base line quantity of oil for injection based on the current fuel consumption of the engine during the current interval. The system may also include an auxiliary flow control device for directing controlled quantities of fresh oil into the engine's lube oil system for maintaining the engine's oil sump at a proper level. The system maintains the quality of the engine lube oil at a level necessary to provide optimal engine protection at all engine operating conditions while also maintaining the oil concentration in the engine's fuel at an acceptable level.

摘要： A control and switching device which links a remote terminal by modems over telephone lines to a local central processing unit (CPU) and a local computer console terminal is disclosed. The device, which is coupled by separate lines to the modem at the local site, the local console and the TTY and ASYNC ports of the CPU, includes a microprocessor, a memory, logic circuits and a switch assembly. The switch assembly includes first, second and third switches which are interlocked and which allow three different levels of remote access of the remote terminal. When the first switch is depressed, the device is powered down, the remote terminal has no access to either the TTY or ASYNC ports of the CPU and the local console is hardwired through the device to the TTY port of the CPU. When the second switch is depressed, the local console is hardwired to the TTY port of the CPU and the remote terminal is electrically connected to the ASYNC port of the CPU. When the third switch is depressed, the local console and the remote terminal both have access to either the TTY port of the ASYNC port of the CPU. A variety of firmware commands stored in the device, some of which may be applied by the local console and some by the remote terminal, depending on which switch is depressed, provide a number of different operating modes, the modes including a conversation mode wherein the CPU is locked out and the local console and remote terminal can communicate directly with each other.

摘要： A device is provided for installing multiple piezometers in a borehole at predetermined elevations. An inner support pipe which may be interconnected with a string of grouting pipe is utilized. A continuous fluid passageway for introduction of grout to the bottom of the borehole results by inclusion of the support pipe as an integral part of the string. A tray member is provided which carries a piezometer embedded in a layer of permeable material. The latter makes a hydraulic connection with the borehole wall. A spring assembly is adapted to move the tray outwardly and radially so as to bring the layer into contact with the borehole wall. A wire restrains the tray against the support pipe so as to permit the device to be inserted into the borehole. A messenger is inserted into the fluid passageway to sever the wires whereupon the spring expands, bringing the layer of permeable material into hydraulic connection with the borehole wall.
