Title: Burner control system
Inventor: ST BERNARDUS JOHANNES CATHERIN
Filed: 1961-10-23
Abstract: 926,805. Photo-electric burner control. WHITE-RODGERS Ltd. Oct. 23, 1961, No. 37970/61. Class 40 (3). [Also in Group XI] A burner control system comprises a flame detector relay, the winding of which is connected in series with a fixed resistor and a voltage dependent resistor, a photoconductive element being connected in parallel with the winding and the voltage dependent resistor. When no flame is sensed the photoconductive cell 50 has a high resistance and the current through the winding 26 is sufficient to pull in the contact 28. When a flame is sensed, the decrease in resistance of cell 50 causes a larger voltage drop in the fixed resistor 42, which reduces the voltage through winding 26 sufficiently for contact 28 to drop out. Operation of control system.-A call for burner operation registered by closure of a thermostat 14 energizes the ignition relay winding 16, and provided cell 50 is unilluminated, the flame detection relay winding 26. Contacts 18 and 28 pull in to start the igniter 52 and to energize the motor relay winding 20. This energizes motor 12 and closes holding contacts 24 which pass current through the bi-metal switch heater 40. The winding 20 is drawing current through the heater 32 and, if no flame is sensed to open contact 28 with a preset time, safety switch 30 opens and has to be manually reset. If a flame is sensed, contacts 28 disconnect the low-impedance winding 20 and the heating of heater 32, through the higher impedance 16 alone is slowed, sufficiently for time switch 38 to move from contact 34 to 36 to disconnect igniter 52 and heater 32. Operation continues until thermostat 14 opens or the flame fails. In the latter case, contacts 28 close and winding 20 is shortcircuited through contact 36. The heater 40 is disconnected and the burner is automatically restarted after the time switch has cooled to make contact 34.

The housing 16 of a vacuum motor 10 is divided into three chambers 35, 36, 37 by two flexible diaphragms 21, 30 movable in repect to the housing and in respect to each other to vary the volumes of the chambers, diaphragm 21 being secured to a hollow actuator which extends through a housing aperture 38 and is connected to its outer closed end to a lever 11 to be positioned, whilst diaphragm 30 is secured to a stem 47 which extends into actuator 42 and is engageable with a split ring 55 thereof whereby when vacuum is applied through a tube 41 to chamber 37 to displace diaphragm 30, diaphragm 21 is displaced in union therewith and when vacuum is subsequently applied through a tube 39 to chamber 36 the diaphragm 21 and hence actuator 42 is moved further into the housing 16.

Abstract: 966,300. Power measuring. J. F. S. CARRUTHERS, and W. WILSON. Nov. 24, 1961 [Nov. 4, 1960], No. 38075/60. Heading G1U. [Also in Division G4] Power measuring apparatus comprises a capacitive voltage divider across spaced conductors supplying the power to be measured, a semiconducting Hall effect member "energized" from said voltage divider, and also intersected by the magnetic field created by current flow in said conductors, the resulting Hall voltage being representative of the product of voltage and current in said circuit. In one embodiment Figs. 1, 2 the lower of the spaced conductors 10, 11 is earthed and carries on a post 13 a brass Faraday screen 12 within which the Hall plate 27 is mounted with its plane normal to the magnetic field produced by current in the conductors 10, 11. The voltage divider is formed by two series connected capacitors. One capacitor is formed by an earthed plate 19, a dielectric disc 23 silvered on both sides and a disc 21 carried by a pin 22. A further smaller capacitance exists between disc 21 and a conductor 10, this capacitance being varied by altering the size of an aperture 25 in an intervening plate 24 secured as is plate 19 to the earthed screen 12. Lead 26 connects the Hall plate across the first capacitor. The Hall voltage is led out via leads 29, 30 to a shielded cable 31, and thence to a watt-meter. The screen 12 is slotted as shown to minimise eddy-current flow therein. A further R. F. embodiment employs a potentiometer 50, Fig. 3, to balance the Hall plate 45 so that there is no P.D. between connections 52, 53 in the absence of a magnetic field. The Hall output voltage is smoothed by capacitors 55, 58, and R.F. chokes 64, 65. The construction adopted, Figs. 4, 5 (not shown) is substantially the same as that of Figs. 1, 2 except that an outer cylinder is provided which encloses the screen and the associated portion of the live conductor 42. To ensure that the magnetic field and the energizing current are substantially in phase the H.T. lead from the Hall plate to the voltage divider may in either embodiment be connected via a transistor biased to render the transistor conducting in operation.
