摘要： 1524559 Ignition systems ROBERTSHAW CONTROLS CO 24 Nov 1975 [2 Nov 1974] 48235/75 Heading F1B [Also in Divisions H2 and H3] An ignition system 10 for a combustion chamber 20 supplied with fuel oil by a burner motor (not shown) comprises electrodes 16, 18 connected to a pulse generator circuit 12 consisting of a pulse generator formed by members SCR1, T1, C3, D4 and R6, a trigger circuit formed by members R1, R2, D1, C1 and D2, and a turnoff circuit formed by members C2, D3, R1, R3 and R4, the diode D4 being of the fast recovery type to assist in the reliable turn-off of rectifier SCR1 and so ensure a multiplicity of ignition pulses during each positive half cycle of the AC supply accross members L1, C3, R7 causing operation of the circuit 12. A typical turn-on and turn-off of the rectifier SCR1 is described for the condition when the AC supply passes through zero and begins its positive rise. Figs. 3, 4 and 5 (not shown), this operation being repeated about forty times during each positive half cycle. After turn-on of rectifier SCR1 by the trigger circuit and discharge of capacitor C3, the latter is charged in the opposite direction by the collapsing field of transformer T1, until rectifier SCR1 is turned off by the resultant reverse voltage applied to its anodecathode circuit by capacitor C3 and to its gatecathode circuit by the turn-off circuit. The high voltage pulse produced by the initial collapse of the transformer field is mostly dissipated in the resistor R6 due to the rapid turn-off of the diode D4, thereby relieving the rectifier SCR1 of this surge of energy and assisting in its turn-off by the action of capacitor C3 and the turn-off circuit. The chamber 20 may include a section to blow the discharges between electrodes 16, 18 into the oil spray. The ignition system may alternatively be used with a micro-wave oven.

摘要： PURPOSE: To provide a liquid level monitoring detector provided with a test function by which a user can check an action of the detector. CONSTITUTION: A test circuit tests an action of a liquid level detector 10. The liquid level detector 10 is provided with a probe 20 to be grounded in a test position. A control circuit 16 monitors a change in capacity of the probe 20 based on the liquid level change in the test position. By means of a test switch 30, the control circuit 16 detects an alarm condition when an input of the probe 20 is grounded. If the alarm is not operated by means of the control circuit 16 even when the test switch 30 is operated, the detector 10 functions abnormally and requires its correction or replacement.

摘要： PURPOSE: To rapidly and easily manufacture a bellows actuator by causing a bellows hermetically fixed to a housing to actuate a linkage and controller in response to pressure differentials. CONSTITUTION: A bellows unit 24 which transmits the pressure fluctuation of an operating fluid to a linkage system 16 is mounted by a support unit 22 and a connecting structure 26 to a case 12 having built therein a control switch 14 which operates in conjunction with the linkage system 16. The operating fluid passes through a capillary tube 42 and enters an operating fluid pressure chamber 39 via a port 40 in a base wall 31 to cause expansion and contraction of the bellows unit 24. This expansion and contraction of the bellows unit 24 moves a rod 48 via a bellows 46 and is transmitted to the linkage system 16. The motion of the linkage system 16 actuates the controller switch 14.
