Title: Safety switching apparatus for a microwave cooking device
IPC: F16P3/08
Filed: 1979-12-07
Abstract: An electrical circuit for a microwave cooker has a safety feature to cut off supply to a microwave emitter when a door is opened but a main switch has failed to operate. A door switch (8) is connected across the supply for the emitter (2) and closes upon actual opening of the door to short-circuit the supply. A subsidiary switch (9) is connected on the load side of the door switch and opens with a main switch (7) in conjunction with an unlocking operation of a door lock. If the door is unlocked but the main switch (7) fails to open, supply to the emitter is cut-off by the subsidiary switch (9) thereby preventing microwave leakage as the door is opened. The action of opening the door closes the door switch (8) to blow a fuse (4) if the main switch (7) fails to open, thereby giving an indication of failure of the main switch. A further switch may be arranged to open after a delay following opening of the door. <IMAGE>

Title: Vehicle Brake Pressure Proportioning Valves
IPC: B60T11/34
Filed: 1980-11-28
Abstract: A vehicle brake pressure proportioning valve has a stepped proportioning plunger (17) movable by brake pressure against a loading spring (26). A control plunger (18) subject to pressure from inlet port (19) follows movement of the proportioning plunger and prevents full operation of a metering valve ball (22). At a particular vehicle deceleration control mass (38) seals off a passage (34), trapping fluid in an annular control chamber (32) and preventing further movement of the control plunger. The proportioning plunger then shuttles to and fro to supply fluid to the brakes via outlet port (21) at a reduced rate. A control spring (43) influences the particular vehicle deceleration at which the control mass seats so that the greater the loading of the vehicle, the greater the magnitude of deceleration at which pressure proportioning starts. <IMAGE>

Title: Power conserving tepe power supply circuit
IPC: H03K3/012
Filed: 1979-07-03
Abstract: A power supply circuit for discharge type detecting circuits comprising a blocking oscillator (1) and a feedback circuit (2) for varying the oscillation period of the blocking oscillator. A detecting circuit acting as a load is connected to a secondary winding (L<u2>u) of a transformer (T) of the blocking oscillator (1). Base biasing for a transistor (T<ur1>u) of the blocking oscillator is controlled by the feedback circuit (2) to which is applied a negative voltage developed in a primary winding (L<u1>u) when the transistor (T<ur1>u) is cut off. As a result, since the oscillation period becomes shorter when the detecting circuit is in operation, power is rapidly supplied, whereas less power is supplied due to a longer oscillation period when the detecting circuit is standing by, whereby total power consumption is reduced.

Title: Method and apparatus for measuring selected characteristics of fluids
IPC: G05D21/02
Filed: 1982-02-23
Abstract: Applications to the printed circuit industry are described in which the concentration of a chemical in a solution is monitored and maintained at a preselected level. Portions of the solution 10 are continually pumped through a microwave sensor 20 that senses the resulting attenuation of the microwave radiation. The attenuated signal detected beyond the solution is compared the the signal as detected in the sensor in advance of the solution. If the signals differe by an amount different from the initial amount, the concentration of the chemical is adjusted accordingly. Means are also provided to accommodate differences in the microwave detectors' responses to microwave radiation as a function of temperature, and delays in dissolving the chemical in solution. Alarm means generate alarm signals if the concentration of the chemical in the solution differs from a preselected concentration by more than a preselected amount. The temperature in a constant head supply tank 16 is controlled in response to a sensor 100 by a heater 102, also the temperature in microwave device 20 in response to a sensor 104, by a heater 106. <IMAGE>

Title: Double wall steam generator tubing
Inventor: PADDEN THOMAS ROY
IPC: G21D1/00
Filed: 1982-12-07
Abstract: Double-walled steam generator tubing for the steam generators of a liquid metal cooled fast breeder reactor prevents sliding between the surfaces due to a mechanical interlock. Forces resulting from differential thermal expansion between the outer tube and the inner tube are insufficient in magnitude to cause shearing of base metal. The interlock is formed by jointly drawing the tubing, with the inside wall of the outer tube being already formed with grooves. The drawing causes the outer wall of the inner tube to form corrugations locking with the grooves. <IMAGE>
