摘要： In an appliance such as an oven for cooking food, the invention contemplates a user rotatable, single knob oven control device which provides both discrete and continuous control signals to the appliance controller. The discrete outputs indicate selection of oven features, and the continuous output the desired baking temperature. These inputs are selected by a user in response to rotation of a user interface knob mounted on a control panel. The control panel provides visual indication of oven cooking temperature selections through a first arc around the knob, and user selectable oven features (such as, e.g., OFF/CANCEL, BROIL, and CLEAN) in a second arc around the knob. The control device comprises a hub having a portion adapted to be drivably coupled to the user interface knob. The hub also includes a flange which has at least one cam. The device also includes a variable resistance element having a rotatable shaft in driving engagement with the hub. This element provides a variable resistance output in response to rotation of the shaft through the first arc. Additionally, the device includes a push button switch which is located external to the variable resistance element. The switch is also located in proximity with the flange such that rotation of the hub will bring the cam in contact with the switch to actuate it. This switch provides a discrete output when actuated by the cam to indicate a selection of one of the oven features.

摘要： A temperature control system for a passenger van having individual temperature selection controls for passengers in the forward and rear sections of the passenger compartment. Separate exothermic heat exchangers for circulation of engine coolant therethrough are provided for the forward and rear passengers. Each heat exchanger is supplied by a coolant control valve and individual blowers provide a stream of forced air over the heat exchangers. A thermistor senses the temperature of the air discharge over each heat exchanger and a controller sums the sensed temperature signal with a user selected relative temperature reference signal provided independently by the forward and/or rear passenger selector inputs and a valve position signal; and, the controller generates a control signal proportional to the summation. An electrical actuator for each valve moves the valve until the sum is a null for controlling coolant flow to each heat exchanger to thereby regulate the discharge air temperature about the individually selected relative levels for the front and rear independently of the selected blower speed. Air conditioning evaporators may be disposed upstream of each of the heat exchangers; and, the thermistors sense the combined effect of heating and cooling and the system continues to modulate coolant flow to the heat exchangers for temperature regulation.

摘要： An automatic control system for regulating the temperature of blower air discharged over a heater core to a vehicle passenger compartment. A thermistor is disposed to sense discharge air adjacent the heater core and provide a temperature signal. An electrical indication is provided of the condition of a servomotor driven valve controlling water flow to the heater core. An electrical reference signal is provided indicative of a user selected relative change of flow discharge air temperature. A signal is provided indicating the speed of the water pump circulating liquid to the heater core. The signals are summed and the valve sums driven until the sum is zero and the valve modulated to maintain the sum at zero for regulating blower air discharge temperature constant.

摘要： A pressure transducer of the type providing a continuous electrical output signal indicative of the variation in sensed pressure having a metallic preferably aluminum armature attached for movement with a resilient pressure responsive diaphragm. A resonant circuit includes a coil disposed adjacent the armature and an oscillator provides current flow in the coil which generates eddy currents in the armature; and, movement of the diaphragm and armature causes the eddy currents therein to alter the effective inductive reactance of the coil and shift the frequency of resonance of the circuit. Circuit means are provided to emit an output signal indicative of the frequency shift for enabling a continuous determination to be made of the sensed pressure on the diaphragm. An auxiliary snap-action switch is provided remotely from the diaphragm and is actuated by a non-metallic rod from the armature passing through the central region of the coil. The circuitry is preferably mounted on a p.c. board disposed to have the switch rod pass therethrough.

摘要： The accumulated number of cycles of an alternating current power supply are counted and a first signal is generated when the count reaches a number representing a desired time lapse and a second signal is generated when a desired multiple of a number have been counted. The timing motor of an electro-mechanical appliance programmer is switched off by said first signal and remains off for a time interval of twice that represented by a second signal.
