Title: Improvements in or relating to electric secondary battery systems
IPC: H01M10/44
Filed: 1939-03-01
Abstract: 525,797. Charging and discharging batteries. GENERAL ELECTRIC CO., Ltd., and RANDALL, H. March 1, 1939, No. 6702. [Class 38 (iv] A battery 1 supplying the control circuits on an electrically propelled vehicle is charged from the supply through a compressor motor 10, and the application of high voltage to the control circuits, in the event of damage to the battery, is avoided by means of a relay 14 connected to the battery voltage and operating when the voltage rises, to connect a resistance 12 across the battery. Thus a suitable potential remains available for the control circuit. Indicating lamps show when the relay 14 has operated. Where a second auxiliary motor 11 is switched in parallel with the first, a relay 17 is effective to reduce the value of the resistance 12 connected across the battery by the relay 13. A relay 19 also controls the connection of the resistance 12 and is operated on overcharge by a coil 20.

Title: Improvements in or relating to apparatus for the control of temperatures
IPC: G05D23/12
Filed: 1927-03-17
Abstract: 290,402. Sandison, A. G. S., and Electroflo Meters Co., Ltd. March 17, 1927. Thermostats.-In apparatus comprising a temperature responsive mem. ber which displaces a pilot valve governing the admission of pressure fluid to a servomotor controlling heating fluid or electricity, the pilot valve and its seating have a continuous relative rotation to lessen longitudinal friction. A bulb containing expansible fluid is located in the enclosure to be controlled and connected by a tube 2 to a helical Bourdon tube 1 adjustably secured to the casing 8 at one end and fixed to a spindle 4 at the free end. An arm 13 is attached to the spindle 4 and connected by links 15, 17, 18 with the pilot valve comprising a piston valve 20 working in a sleeve 21. At its lower end the pilot valve carries a disc 23 having a series of vanes 24 adapted to be acted upon by jets of the pressure fluid from nozzles 75 to continuously rotate the valve, the speed of rotation being limited by the drag of the vanes which are totally immersed in the oil or other fluid in a tank 45. The disc 23 also damps longitudinal movement of the pilot valve. Ports 25, 26 in the sleeve 21 are connected by tubes 27, 28 to the servo-motor cylinder 29 the piston-rod 33 of which is connected with the means for regulating the supply of the heating medium, e.g. fuel, steam or electricity. To prevent hunting a pin 34a on the piston rod 33 engages a link 35 adjustably pivoted at 36 and connected at 41 with the link 17 and with a link 42 pivoted to the casing at 43 so that movement of the servo-motor tends to restore the pilot valve to neutral position. To vary the sensitivity the link 35 is pivoted on a post 37 adjustable along a slot 38 in the casing 8 and fixed by a nut 39. To alter the temperature at which control is effected the Bourdon tube 1 is secured to a rotatable support 6 having pins 9 passing through the casing and engaging a disc 10 having a scale of temperature engraved upon it and registering with an index 12. A nut 11 clamps the support 6 and disc 10 in the adjusted position. The casing 8 is secured to the tank 45 containing the oil or other fluid and enclosing a pump housing 46 the open under side of which is covered by gauze straining material 48. Within the housing 48 are three pump cylinders 47 the pistons 62 of which are driven by connecting-rods 63 from a central crank-shaft 51 mounted in a bracket 50 and rotated by a worm 53 the shaft 58 of which passes outside the casing and is driven by an electric motor. The pumps draw oil from within the housing 46 and discharge through pipes 71 to a manifold pipe 72 from which the pressure fluid passes to a port 74 in the sleeve 21 of the pilot valve and also to the jet nozzle 75 and a relief valve 76 loaded to discharge at a given pressure. The discharge from the relief valve is taken by a pipe 77 to lubricating passages for the bearings of the crankshaft 51 and worm shaft 58. All oil discharge drains back by gravity into the tank 45.
