Abstract: A control instrument is used for the manually continuously adjustable supply of electric power to electric hot plates in the form of individual power pulses. The control instrument contains a switch, operated by a bimetallic member, whose heater is controlled by an electronic circuit and supplies current to the heating means in individual half-waves. An automatic initial cooking device with an electronic timing member is provided which, during the initial cooking phase, reduces the power supply to heater in a predetermined ratio and consequently correspondingly increases the power supplied to the electric hot plate. The automatic initial cooking device is automatically switched on by the control instrument knob. By rotating the control knob beyond a median power limit the automatic initial cooking device is switched off.

Patent EP-0018221-A1 (EP)
Inventor: MEYER EMILIO G
IPC: G01N25/28
Filed: 1980-04-18
Abstract: A detector or measuring bridge (12) and a reference bridge (14) receive input signals from a regulated power source (20) and generate output signals through feedback control circuits (56, 68) to a galvanometer (76). Each bridge (12, 14) includes a filament (32, 40) exposed to a gas being measured. The detector bridge filament (32) is coated with a catalyst and the reference bridge filament (40) is not. Initially, the bridges are calibrated for operation of the exposed filaments at a preselcted resistance and temperature. In the presence of a gas containing combustibles, the catalyst on the detector filament (32) promotes combustion of the gas thereby increasing the temperature and resistance of the detector filament (32) to unbalance the detector bridge (12) and vary the magnitude of the output signal to the feedback control circuit (56). An operational amplifier (80) of the control circuit (56) is thus actuated at a reduced operating level to switch a transistor (TRI), connected to the power source (20) and an input (44) to the detector bridge (12), from a conductive state to a nonconductive state to thereby adjust the voltage level applied to the detector bridge. The bridge (12) is returned to a balanced condition, and the detector filament (32) is returned to its initial temperature. The variation in the voltage supplied to the detector bridge (12) is proportional to the concentration of combustibles present in the gas. The readout of the galvanometer (76) provides a quantitative measurement of the combustibles in the gas. Adjusting the voltage applied to the detector bridge (12) maintains the detector filament (32) at a constant temperature to increase the operating life of the detector filament and reduce evaporation of the catalyst on the filament.

IPC: F24F11/02
Filed: 1980-05-28
Abstract: A temperature control system including a pushbutton controlled, pneumatically operated actuator for controlling a vehicle heating and air conditioning system are disclosed. A plurality of pushbutton operated valve members (112) nables an operator to control the system by selectively communicating a vacuum source connected to each valve member to a given position within a vented air-piston chamber (72). A piston (74), slidably received in the chamber, is moved along the chamber by the differential pressure across the piston face until a seal member (76) located around the piston periphery blocks the orifice of the passageway (70) communicating with the vacuum source, thus substantially sealing off the chamber from the vacuum source and preventing further piston movement. The number of output positions of the actuator piston in one embodiment of the invention is equivalent to the number of pushbutton valves which communicate the vacuum source to the air chamber. Piston movement is used to control actuation of associated heating and air conditioning system components.

The presence of the exchanger not only makes possible heat recovery, but also leads to better filtration, while ensuring simultaneous cleaning of the exchanger and of the grille. <IMAGE>

Abstract: Two permeable-to-gas patterns (68) form an inner cavity (54) of desirable configuration and are enclosed by non-permeable halves of the pattern box, forming an outer cavity or flow space (70). The pattern box (32) is mounted on two plates of the rotatable cage assembly, selectively positionable in at least three positions: charge, discharge, and transfer. Above the pattern box (32) are pivotally mounted material supply means (44), sealing means (96), and a trimmer (46). Below the pattern box is a receiver (16) of an airless conveyor (14) for recirculation of the discharged unhardened material. The pattern box is connected to two manifolds: (61, 63) one (63) for consecutive supply of catalyst gas and the compressed air, another (61) for axhaust and venting. After material has been blown with the help of compressed air from the material supply means into the pattern inner cavity, it is sealed and the air is flushed out of the system by compressed catalyst gas introduced into the pattern box for about one second. Said gas then penetrates to desirable depth into material's outer layer starting polymerization and curing of its binder. After a few seconds, unsealed pattern box assembly is turned upside down and compressed air is blown into the pattern box, dislodging unhardened portion of the material out of the inside of the produced shell-like product. Consequently, the pattern box is opened and the product is transferred from the apparatus to a suitable place outside the machine.
