Title: Method for forming a ball and socket joint
IPC: B21H8/00
Filed: 1971-02-18
Abstract: 1393523 Making ball-and-socket joints; rolling GLACIER METAL CO Ltd 17 May 1972 [18 Feb 1971] 4902/71 Headings B3M and B3A A ball-and-socket joint is formed by advancing tubular material for both ball-and-socket between the helical grooves of rollers which form the ball surfaces of at least the socket. In one embodiment a preformed tube 21, Fig. 3, is surrounded by a tube 25 having a bearing liner 24. The assembly is rolled between grooved rollers similar to those in Fig. 1, and the tube 25 is deformed around the tube 25 and then severed by cutting surfaces 17 on the rolls to produce ball-and-socket joints, Fig. 4. Subsequent external rolling of the joint can be effected to give a desired bearing clearance between the joint parts. The rollers in Fig. 1 are shown deforming a tube 11 into ball parts 18; the parts are not severed from the tube, however, when producing the tube 21 of Fig. 3.

Title: Systems for indicating the effective age of electrical apparatus
IPC: G01K3/04
Filed: 1945-03-01
Abstract: 623,539. Electric meters. BRITISH THOMSON-HOUSTON CO., Ltd. March 1, 1945, No. 5081. Convention date, March 1, 1944. [Class 37] [Also in Groups XIX, XXXV and XXXVIII] To obtain an indication of the true or effective age of electrical apparatus which ages more rapidly when operated above a certain temperature, a recording and indicating instrument is used which is operated from the apparatus and controlled by a thermallyresponsive device connected to. the apparatus. As applied to a transformer 7, the age-indicating means comprises a motor 10, operated from the transformer, driving through speed-reduction mechanism 12 a disc 13 which rotates a disc 14 frictionally through a magnetic ball 15 to drive, through further speed-reduction mechanism 18, a counter 19. The arrangement is such that the counter shows the physical age of the apparatus in equivalent years of service. The position of the ball 15, which controls the speed ratio between discs 13, 14, is controlled by a bimetallic thermostat 16 located in the oil &c. in the transformer tank 8, so that the counter registers faster when the temperature of the transformer increases. In a modification, the ball 15 itself is driven by the motor 10 to rotate the disc 14, and the position of the ball is controlled by a cam face movable by levers controlled from a thermalresponsive device comprising a metallic bellows, a capillary tube and a bulb which contains a liquid and is heated by a resistance coil to the temperature of the transformer. An indication of the rate at which the apparatus is ageing is given by a device 22 of the speedometer type. The whole arrangement may be replaced by a kilowatt-hour meter 51, Fig. 5, having the voltage terminals 52 connected to the transformer, and the current terminals 53 in series with a small transformer 55 in the transformer circuit and a resistance 56. The resistance 56 is such that its resistance diminishes with increase in temperature, and it is heated by a coil 31 to the temperature of the transformer. The scale markings of the meter are graduated in years and fractions thereof. In a modification of Fig. 5, the current-leads of a reactive kilovolt-ampere-hour meter are in series with an inductance coil having a magnetic core of such a nature that permeability rapidly decreases with increasing temperature, such as an alloy consisting of 68 per cent iron and 32 per cent nickel.

Abstract: 744,835. Electric lighting fittings. IONLITE, Ltd. Feb. 24, 1954 [Feb. 24, 1953], No. 5171/53. Classes 75(2) and 75(4). An electric lighting fitting comprises an upright support member carrying electric illuminating means, and which extends through a lantern casing comprising a pair of dished elements arranged in opposition with their horizontal rim portions in engagement with one another, at least one of said elements being slidable on the support member. As illustrated the lantern casing comprises upper and lower dished elements 11, 12 mounted on a tubular support 13 which extends either downwardly as a standard or upwardly as a pendant. The elements 11, 12 are formed of transparent or translucent plastic material and the element 12 rests on a collar 19 slidable on the support 13, and fixed in position by a screw 30 whilst the element 11 is secured to a collar 28 slidable on the support 13 and fixed in position by a screw 29. The element 11 may, alternatively, be of metal or other opaque material. A waterproof joint between flanges on the rims of the elements 11, 12 is provided by a soft rubber or other packing ring 24 which is received in grooves in the flanges. Within the lantern five tubular discharge lamps 31, 32, 32a, 33, and 33d are attached by slips to a framework 34 supported upon an annular housing 36, fitted on the tube 13 for containing the transformers and ancillary electrical apparatus' supplying the lamps. The lamp 31 is substantially circular whilst the remaining lamps are of zig-zag form. The lower end of the tube 13 is open so that cooling air may pass through the tube to be diverted by a plug 44 through holes 45 into the housing 36 to cool the electrical apparatus, and to pass from the housing 36 through holes 46 into the upper part of the tube 13. If such cooling is not required the holes 45, 46 are omitted or the ends of the tube 13 are closed. The electrical apparatus may, alternatively, be mounted on a horizontal partition fixed to the support tube, or be mounted directly on the latter. An electrical control switch may be provided which is opened by separating the two elements of the lantern casing, or which prevents separation the two elements when in the closed position.

Title: Improved means for automatic control of starting and stopping devices for internal combustion engines
IPC: F16N29/04
Filed: 1933-02-25
Abstract: 415,460. Starting prime movers. CARTER, F., CARTER, E., and BLACKSTONE & CO., Ltd., Rutland Engineering Works, Stamford, Lincolnshire. Feb. 25, 1933, No. 5771. [Class 38 (iv).] The fuel supply to an internal-combustion engine is controlled by the pressure of lubricant, of which the supply to the control device is initiated by operating the engine starting switch. Upon closing a push button switch 42, solenoids 37, 17 are energized thereby closing the starting motor 38 switch and moving a valve 14 to the right respectively. The valve then permits oil pumped by the engine to pass through ports 19, 20 to a cylinder 1 and actuate a piston 2 connected to the fuel pump or throttle valve. The lubricant supply is partially cut off toward the end of the stroke by a piston valve 21. Should the oil pressure fail the piston 2 is returned by the spring 3 and cuts off the fuel supply. The engine is normally stopped by closing a second push switch 41 which energizes the solenoid 16 and returns the valve 14 thereby connecting the cylinder through a drain 18 to the sump. When a float operated &c. automatic starting switch 39 is employed the motor circuit is broken at 29, 30 after starting by a switch 8 which is tripped by the piston 2 at the end of its stroke and simultaneously closes a gap 31, 32 in the stopping circuit. When the switch 39 moves to contact 45 the solenoid 16 is energized as before and the returning piston 2 again trips the switch 8 into the starting position. A switch 40 may be employed to isolate the automatic starting switch 39 when it is desired to use the push switches 41, 42.
