Title: Process and machine for the manufacture of incandescent lamps, thermionic valves and like apparatus
IPC: H01J9/38
Filed: 1925-10-30
Abstract: 242,303. General Electric Co., Ltd., (Assignees of Patent Treuhand Ges. f³r Elektrische Gl³hlampen). Oct. 31, 1924, [Convention date]. Making lamps.-The stems and internal parts are sealed into the bulbs, and the bulbs are exhausted and, if required, gas-filled, and finally sealed off, while travelling continuously in a single path. In the machine described, the stems and bulbs are mounted in carriers which are arrested in the positions 1 - - 24 during each revolution of the machine table, the exhaust tubes being connected by rigid tubes to a central valve disc b connected to the pumps and gas supplies. In the position 1, the piece of exhaust tube remaining from the lamp finished in position 24 is ejected by compressed air, and new parts are assembled in position 2. The exhaust tube is gripped in a rubber cylinder l, Fig. 3, when its ends are compressed between metal blocks l<1>, l<2> by the downward movement of links m having pins m<2> engaged in cam slots in a rotatable cap m<4>. This is rotated by a clutch n, which is lifted as it rotates by a pin n<3> running in a cam slot. Jaws l<4> pivoted to the block l<2> are closed by wedges as the block descends and grip the exhaust tube. At the loading position a bulb is placed in a fork i, Fig. 7. which has been raised and held in the raised position by a detent i<3>. At the next position, the bulb is pulled down to enclose the stem by a pawl p<2> carried by a rod p<1>. The cap g<4> of the exhaust-tube holder is raised by a roller g<6> running on a cam track g<7> to the position shown in broken lines in Fig. 3, to support the stem foot h during the sealing-in operation. The sealing-in burners q<1> are mounted on a fork q, Figs. 2 and 8, adapted to be rotated by gearing r, r<2> until arrested by a cam-operated detent, a screw q<7> enabling the height of the burners to be adjusted. When a stem has been sealed in, the bulb is raised in position 9 to stretch the glass at the seal. The surplus ring k<1>, Fig. 3, of glass severed from the mouth of the bulb passes between fingers u, Fig. 2, which crush it. From positions 11 to 23 the sealded-in bulb traverses an arched tunnel x in which it is kept hot while being exhausted and, if required, gasfilled. Before entering the tunnel, hooks w<2>, w<3> bend up the leading-in wires to protect them from the sealing-off burners. If a defective bulb arrives at position 11, its failure to exhaust properly causes a gas-valve y to operate to feed a burner y<10> which seals off the bulb. Sound bulbs travel on unsealed to the finishing pumps. At position 24 a radially moving fork z, Fig. 11, supports the bulb while it is sealed-off by burners z<1>, a hook z<5> removing the leading-in wires from the heated zone,

Patent GB-1554466-A (GB)
Title: Automatic train control
IPC: B61L25/04
Filed: 1976-07-02
Abstract: The information is written into memories at those block sections which are occupied by the train. This information is additionally written into at least the memory of a further block section provided the route is set and the associated signals are set to "go". The information in the occupied block section is retained until the train has left it. The number of the train thus precedes the train. Therefore, it is no longer necessary to transmit train control information in a costly manner from section to section in order to permit unimpeded passage of the train in the case of short block sections. If a train travels past an opened signal, it not only clears the memory associated with the previous block section but all the memories which are associated with the block sections lying ahead. In the case of a fault on the route, for example, due to the failure of the points monitoring system or due to the stop position of a signal without the passage of a train, the information in all the subsequent memories is cleared.

Title: Improvements in method and apparatus for the vaporization of liquids
Inventor: KEHOE EDWARD CHARLES
IPC: C02F1/08
Filed: 1964-07-04
Abstract: 1, 040, 782. Distillation of liquids, particularly water. SALINE WATER CONVERSION CORPORATION. July 4,1964, No. 27673/64. Heading B1B. Liquids are distilled from solutions of non- volatile solutes by heating the solution and introducing it through line 17 to the upper end of a column 10 which contains loose packing 11, such as Raschig rings, so that the solution flows down in film-form over the surface of the packing, while the pressure in the free space of the packing is maintained such that some of the solvent vaporizes gradually from the down-flowing films of solution. The vapours flow from the lower end of the packing, through annular slot 61, into contact with cooling coils 54, and the condensate which collects in trough 58 is withdrawn through line 59. The residual solution, which collects in sump 14, is withdrawn through line 23. The walls of the column are insulated from the condenser by lagging 56. Non- condensable gases are withdrawn from the condenser by vacuum pump 36. The column may have a frusto-conical shape in order to accommodate the larger volume of vapour in the downward direction. Potable water may be obtained from sea water by employing three column/condenser units connected to form a vertical series-flow system. The sea water is pumped up through the condenser coils of the third unit (i.e. the last evaporation stage) and then successively through the condenser coils of the second and first units. The sea water leaves the condenser coils of the first unit at 85‹F., and is then raised to 100‹F., e.g. by using it as coolant in the condenser of a power plant. The heated sea water is then conveyed to the head of the packing in the first unit. After flowing through the packing of the first stage, the sea water flows successively through the packing of the following two stages. Aboard ship, sea water is preheated in the condenser of an auxiliary turbine, and the heated water then distributed over packing in a honeycomb structure. The steam withdrawn from the base of the structure is condensed in the condenser attached to the main propulsion turbine.

Title: Improvements relating to the cleansing of rigid materials
IPC: C23G5/06
Filed: 1934-09-27
Abstract: Metal and other articles are cleaned and degreased by treatment at a raised temperature with an aqueous emulsion of a volatile solvent, preceded and/or followed by one or more treatments with a solvent of fat used cold, hot, or as vapour.  Preferably the emulsion also contains a substance which <PICT:0444818/III/1> hinders tarnishing of the articles and may be promotes stability of the emulsion; suitable agents are phenols, and organic bases, e.g. dibutylamine, aniline, and pyridine.  Solvents specified are trichlorethylene, perchlorethylene, and carbon tetrachloride. Emulsifying agents used are alkali, amine-, zinc-, calcium-, or other metal-soaps of resinic or fat acids; sulphonated resinic or fat acids; wetting agents commonly used in the textile industry. An emulsion suitable for freeing metal articles from dust and oil or polishing preparation is composed of 25--30 per cent of trichlorethylene, 1--2 per cent of emulsifying agent, 0,5--1,0 per cent of agent hindering tarnishing, and water. The process may be carried out in open or closed metal-cleaning apparatus provided with a reflux condenser or a solvent-recovery device.  Conveniently the articles are washed in emulsion in a tank 1 and then successively in solvent in tanks 2, 3, each tank having cooling coils 4 above the liquid level.  The contaminated solvent in tank 2 overflows through a pipe 7 to a water-separator 6, from which the water returns to the tank 1 by a pipe 5, while the solvent passes by a pipe 9 to a still 10 and thence to a condenser 12 and tank 3.  Or the contaminated solvent is run from tank 2 direct to the still, and the water-separator is arranged beyond the condenser.  In a simpler apparatus comprising only an p emulsion tank and one solvent tank the used solvent is sucked through a filter, removing water and emulsifying agent, and returned to the solvent tank.
