Title: Improvements in and relating to lamp sealing machines
IPC: H01J5/24
Filed: 1944-12-15
Abstract: 586,704. Making electric lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 15, 1944, No. 25213. Convention date, Dec. 15, 1943. [Class 39 (ii)] In a lamp sealing machine comprising a sealing head having means for holding the bulb in .a vertical position a spindle for supporting the mount in sealing relation to the bulb, and means for advancing the head through a plurality of stations where flames from burners are directed against the rim portions, means are provided at one of the fusing stations for causing to press the parts upwardly to form a seal, the spindle being retracted when the head leaves the station. As shown each head comprises a spindle 15 having a socket 17 into which is fitted a hollow section 18 which carries a flare mount support 20 which is hollow to allow for the accommodation of an exhaust stem and lead wires. A hollow support rod 22 is connected to an exhaust system through a hole in a boss 25 and an annular space 26 between spindle 15 and a sleeve 13. The tube 50 is held in a vertical position by a suction holder 23 comprising a gripping portion 32 fitted with a rubber gasket 31. A hand operated slide valve connects the chamber 32 to the exhaust system or alternatively to the atmosphere. Each head, which is fitted with a driving pulley 14 and is rotated by a belt 60, is moved round intermittently in a counterclockwise direction. At stations A, B, J and K the rotation of the heads is stopped by a bar 75 which engages a pin 81 in the pulley 14. This bar is held in position by a spring loaded dog 78 which allows it to open and the head to turn for an extra revolution if the pin 81 strikes the bar too fiercely. A tube and a mount 51 having no exhaust tube are loaded at B and are heated by fires 52 and 53 at stations C and D. At station E a tappet 16 on spindle 15 engages a roller which is fixed to a pivoted arm having a counterweight at the opposite end. This raises the spindle 15 and forces the tube and mount together, the fires being such that they are fused together. On leaving this station the spindle drops to its original position and at station F it encounters a roller pivoted to a bracket which again raises the spindle and forces the flare and mount together. At station G a further sealing fires are encountered and after leaving this station the spindle engages a track 76 which lifts the spindle during travel to the annealing station H, since the lead wires are resilient and the mount tends to tip when not supported. Suitable fires at station H control the rate of cooling. The bulb is removed at station J and at station K a flared mount with exhaust tube is placed on the head, the bulb is reversed and the process repeated until at station A the bulb is unloaded. As the flare mount has an exhaust tube this supports it against tipping and the track 76 is not required.
Patent GB-252398-A (GB)
Abstract: 252,398. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Hodgkinson, F.). May 22, 1925, [Convention date]. Regulating or controlling. - A system for controlling a supply of fluid, such as lubricant, comprises a main pump 73 drawing from a tank 72 through a pipe 80 and delivering through pipes 81, 82 to an accumulator 83 from which the oil passes at reduced pressure through a pipe 92 to the bearings of the turbine &c. 71. The oil from the pump flows also to the fluid-pressure relay 76 of the governor 77 controlling the main stream valve 75 of the turbine. Excess oil flows from the pipe 92 through a pipe 105 to a port 16 in a regulator 10 controlling the starting of an auxiliary pump 74. The port 16 opens into a cylinder 13 provided with a port 20 through which the excess oil flows to a pipe 21 leading to the tank 72. The port 16 communicates also with the lower portion of the cylinder 13 under the piston 24', so that the oil pressure tends to lift the piston against the pressure of a weight 23 on the piston rod 22. High-pressure oil passes from the pipe 81 to a port 33 in a relay cylinder 12 containing a piston 32 which controls the steam valve 55 of the auxiliary pump through a lever 59, and rods 58, 57. The high-pressure oil passes through a space 34, port 35. spaces 36, 39, and passage ,42 to the lower side of the piston 32, forcing it up and closing the valve 55. Should the pressure in the system fall, the weight 23 forces down the piston 24<1> and a piston 24 which partly covers the port 20 and thus reduces the excess of liquid flowing from the system to the waste pipe 21. Should the pressure fall further, the port 20 is fully closed, and the high-pressure oil passes from the port 33 through port 35, spaces 36, 41, and passage 43 to the upper surface of the piston 32, forcing the piston down, and opening the valve 55 to start the ausiliary pump. In another form of regulator, a weight is suspended by rods from a yoke on the head of the piston rod 22, and tends to be raised by a piston exposed to the steam pressure on the outlet side of the valve 55. When it rises the relay piston 32 is operated to close the valve 55.

Title: Improvements relating to the examination of gaseous mediums for minute particles suspended therein
IPC: G01N21/72
Filed: 1952-10-08
Abstract: 716,163. Furnace observation devices. GENERAL ELECTRIC CO. Oct. 8, 1952 [Oct. 9, 1951], No. 25251/52. Class 51 (1). [Also in Group XL (b)] A gaseous medium is tested for particles suspended in it by causing the particles to emit radiation, e g. by heating, the energized particles then causing them to pass a position at which the radiation from each is detected. As shown, air to be examined is drawn into tube 17 by the flow of a combustible gas entering tube 14 through a tube 16. The combustible gas and air mix in tube 14 and are burned at the burner 13. The heated particles rise in the flame and the light given off by each particle is received by a photo-electric cell 23 which is positioned behind a narrow slit 19 in a mask 18. Thus as each particle passes the slit it gives rise to a pulse in the output of photo-electric cell 23 which is fed through a pulse-shaping circuit 25 to a counter 26. An image of the flame may be focussed on to the slit in the mask by a lens 21 and the light from the particle is selected by means of a filter 22. A heat insulating window is supported between the flame and the window. An indication of particle size may be obtained by making the counter sensitive only to pulses of a certain amplitude. This may be accomplished by adjusting cell sensitivity or the sensitivity of the pulse shaping circuit.

Title: Improvements in or relating to heating systems for buildings and the like
IPC: F24D3/08
Filed: 1952-10-08
Abstract: 738,501. Domestic and factory hot-water supply systems ; heating buildings. BISHOP, G. A., SMITH, L. C., and TURPIN, F. B. Oct. 8, 1953 [Oct. 8, 1952], No. 25264/52. Classes 64 (1) and 64 (2).  In a system in which a hot gas or liquid, e.g. water, is circulated from and back to its source, such as a storage tank for water heated by the exhaust steam of a power station, by flow and return pipes 1, 2 to an installation, e.g. in a distant building, for space-heating and for indirectly heating a domestic hot water system, the space-heating and water-heating circuits la, 1b are connected in parallel between the pipes 1, 2 whilst a valve 9 in the space-heating circuit is controlled by a switch 11 operated upon a change of pressure of the hot fluid. The switch 11 operates by way of a thermal delay switch 12 on a relay 13, which functions at each alternate energization only, to open or close the valve 9 by means of its motor. Thus, by stopping a pump 4 when the space temperature is high, the fluid pressure is caused to drop and the switch is thereby operated to close the valve 9 and cut off the supply to radiators 6. Immediate re-starting of the pump 4 restores, after the temporary cut off, the fluid flow to the circuit 1b and to its calorifier 8 heating the domestic hot water circuit 8a. The rebuilding of fluid pressure operates the switch 11 once again, but the relay 13, by its nature, does not cause the valve 9 to open this time. The valve 9 is re-opened, when necessary, by stopping the pump again. Subsequent re-starting of the pump operates the switch 11 but not to cause the relay 13 to function and the valve 9 therefore remains open. The switch 11 may be one which operates only when the fluid pressure falls, in which case a simple relay replaces the two-step relay 13. An injector 10 returns a proportion of water cooled in a space-heating radiator 6 to the inlet of the radiator if the main water supply is too hot for space-heating. The Provisional Specification refers also to fluid systems which are not for heating.

Abstract: 1,249,759. Washing machine driving arrangement. SIEMENS A.G. 26 May, 1970 [24 May, 1969], No. 25277/70. Heading D1A. A drum-type washing machine has a twospeed pole-change electric motor 5 movably mounted relative to a tub 1, a belt transmission between the motor and drum having a fixed diameter pulley 2 and a pulley 4 the effective diameter of which is automatically changed under centrifugal control when the motor speed is changed whereby the drum speed changes in a greater ratio than does the motor speed, and tamper means 9 to resist relative motion between the drum and motor due to drum unbalance and oppose but not prevent the relative movement when the diameters of the pulley 4 is changed. The motor may be pivotally mounted (Fig. 1) or slidably mounted (Fig. 2) relative to the tub. The belt is movable axially of the pulley 2 as the belt is moved axially by the pulley 4 when its effective diameter changes. The centrifugal control changes the belt transmission ratio when the motor has reached its maximum torque speed or after a short delay.

Title: Improvements in or relating to negative electrodes for electric accumulators
IPC: H01M4/50
Filed: 1922-09-19
Abstract: 187,584. Gross, C. Oct. 17, 1921, [Convention date]. No Patent granted (Sealing fee not paid). Electrodes.- A negative electrode for an accumulator consists of an oxide of manganese together with a hydrogen-transmitting substance such as palladium or a metal of the platinum group. The mixture may be pressed into the form of a plate or it may be attached to a grid. The mass may be rendered porous by adding a chlorine or bromine compound of manganese or other metal in the same group, the halogen being subsequently removed by chemical or electrolytic means. In an example manganic oxide is added tn a saturated solution of manganese chloride containing 1 per cent of palladium chloride to form a dough which is pressed into the form of a plate or introduced into a metal grid. The plate is then dried and placed in sulphuric acid whereby a part of the halogen is liberated, the plate being then ready for use as an accumulator electrode. During the first charge the manganic oxide is reduced to manganous oxide, and during the subsequent discharge the remaining halogen is liberated. The Specification as open to inspection under Sect. 91 (3) (a) states that the active material may consist of an oxide of a metal capable of forming several oxygen compounds, porosity being obtained bv the addition of a chlorine or bromine compound of the same metal or a metal in the same group. This subject-matter does not appear in the Specification as accepted.
