Title: Improvements in and relating to starting means for electric discharge devices
IPC: H05B41/08
Filed: 1942-12-01
Abstract: 554,225. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 1, 1942, No. 17067. Convention date, Dec. 6, 1941. [Class 38 (v)] An electric discharge lamp has a starting circuit including an automatic switch responsive to energizing the circuit for closing it and a second switch also responsive to energizing the circuit for closing the circuit independently and suspending further operation of the firstmentioned switch if the lamp fails to start. In the example, a bimetal strip 30 and two bimetal contact arms 25, 26 are provided. If 25, 26 close on slow discharge, and subsequently open in the normal way, and the lamp starts, strip 30 does not function. If repeated closings and openings of 25, 26 fail to start the lamp, the cumulative heating by the glow causes each end of strip 30 to close on to the nearest strip 25 or 26 and the short sircuit prevents subsequent glow. The strip 30 remains bent under the heating effect of the current therethrough. In a modification strip 30 is of inverted U-shape and makes contact with strips 25, 26 near their points of mounting. Specifications 538,072 and 542,853, [Group XL], are referred to.

Title: Improvements in and relating to electric protective gear for mine hoists and the like
Inventor: SIMONS DAVID SPENCER
IPC: B66B5/10
Filed: 1954-06-16
Abstract: 802,867. Mine - hoist protective gear. BRITISH THOMSON-HOUSTON CO., Ltd. May 27, 1955 [June 16, 1954], No. 17723/54. Class 78 (5). [Also in Group XXXVII] As shown, a two-cage mine hoist is driven by an induction motor M having forward and reverse contactors F, R, with operating coils OCF, OCR, and a rotor rheostat C controlled by driver's lever DL through a servo device SM. Movement of the driver's lever in any forward position causes contact FA to engage contacts 7, 8, in series with coil OCF, a contact RA similarly closing contacts 7, 9, in circuit with coil OCR during reversal. The circuits of coils OCR, OCF, are completed through contacts S1, S2, of safety relays OCS1, OCS2, and a releasing solenoid BS for an emergency brake is controlled by contacts S1B, S1C, and S2B, S2C, of these relays. When one of the cages approaches within a predetermined distance of the bank at the bottom of the shaft, either a switch DI1 or a switch DI2 will be open according to the direction of the wind. Contacts LC1 shunt switches DI1, DI2, and are closed in the " off " position of the controller and during a range of movement in either direction, such range corresponding to an increase of torque to a predetermined value. The safety relays have holding contacts S1H, S2H, shunted by contacts MC1, closed in the " off " position of the controller, and contacts Bl, closed when the brake is applied. The safety circuit is thus automatically re-set when the controller is returned to the zero position and the brake applied. When either of the depth switches DI1 or DI2 are opened, the safety circuit is maintained by the contacts LC1 provided that the control lever is not moved to a position applying to the winder a torque greater than the predetermined value. Interruption of the safety circuit de-energizes the motor and applies the brake so that the speed at which a cage approaches the stop at the bottom of the shaft is limited. After one of the cages has reached the bottom of the shaft movement of the cage in the opposte direction is not prevented, since, although in the case of a forward wind the switch DI1 will have been opened, for example, when the lever DL is moved in the reverse direction, the contacts C2 will shunt the contacts DI1. The contacts C1 operate similarly with respect to the switch DI2. A switch OS may be closed when the hoist is not being used for carrying personnel. The hoist may be driven by other types of motors, electric or non- electric.

Title: Device for controlling the composition of the fuel-air mixture in an oil burner
IPC: F23D5/14
Filed: 1966-04-22
Abstract: 1,089,418. Fuel and air supply to burners. W. FISCHBACH, [trading as BLECHUND METALLWARENFABRIK ROBERT FISCHBACH]. April 22, 1966 [April 23, 1965], No. 17771/66. Heading F4T.  A burner 1 is supplied with air from a blower 2 and fuel through pipe sections 25, 25<SP>1</SP> from a control 3 which comprises a float chamber 13, in which oil from a pipe 17 is kept at a constant level by a float and valve arrangement 14, 16, and a bell 18 having its rim immersed in the oil and which is connected by a pipe 29 to the suction side of the blower, so that in operation of the blower the oil level 48 in the bell rises and oil enters an inlet pipe extension 21 of pipe section 25 through an opening 22, the pressure in pipe 21 being maintained equal with that in the bell due to pipe bore 47. The greater the delivery volume of the blower 2 the greater the drop in pressure at the suction side of the blower and the higher the oil level 48 in the bell so that an oil column of increasing height forms above opening 22 and the delivery of oil to the burner, which is proportional to this height, is increased. The pipe section 25 is formed with a U-bend 26 which retains an accumulation of oil 26, and a magnetic valve 26<SP>1</SP> can be used to separate the two pipe sections. In a modification air for the blower is drawn through a suction pipe 30 having a Venturi constriction 31, and pipe 29 is replaced by a pipe 32. This modification may be adapted by connecting the float chamber 13, normally vented to atmosphere, to pipe 30 either upstream or downstream of constriction 31 by means of a pipe 34. The position of opening 22 with respect to level 15 (if normally below this level then valve 26<SP>1</SP> is. closed when the burner is inoperative), may be adjusted by rotating pipe 21 within a screw-threaded connector 24 by which it joins pipe section 25. For this purpose the pipe 21 extends through an opening 23 in the top of the bell and is provided with a screwdriver slot 44, Fig. 2 (not shown). Sealing rings 40, 42 retained in peripheral grooves of the pipe 21 prevent oil seeping past the threaded lower end of the pipe and through opening 23. The burner comprises a pan 4 from which fuel/air mixture is fed to a head 5 to issue through gaps 7 between burner plates 8. The flame is deflected at a collar 9 of a lower plate 10 and heats the pan externally to vaporize oil therein.
