Title: Improvements in or relating to metal vapour electric converters
IPC: H01J13/32
Filed: 1937-10-07
Abstract: 503,531. Metal vapour converters. GENERAL ELECTRIC CO., Ltd., and GALLIZIA, E. Oct. 7, 1937, No. 27239. [Class 39 (i)] In a metal-vapour electric converter in which part or the whole of the tank is arranged to be cooled by a flow of gaseous fluid derived from means for passing the fluid over the said part or whole of the external surface of the tank, at least one tube or duct extends through the space within the tank and is adapted to be traversed by gaseous cooling fluid other than the flow which serves to cool part or the whole of the external surface of the tank, solely or substantially solely to cool the space within the tank. Air is driven by the blower 5 through the jacket 4, and, by suction at the mouth 7 and by convection, is drawn through the tubes 6 and 8, Fig. 1. When the blower, which may be controlled by the temperature of the air issuing from the jacket, is slowed or stopped, circulation through the tubes 6, 8 still continues by convection. In a modification, the jacket extends only part way up the converter and, of the tubes 9, 10, one has its lower end 11, Fig. 2, within a narrower part of the jacket, so that, when the blower is working, most of the air from the jacket passes through the tube 9, and, by suction at a chimney 15, air, some of which comes from the jacket 4 is sucked through the tube 10. When the blower is switched off, circulation is entirely by convection. The chimney 15 may be omitted. Specification 459,558 is referred to.

Abstract: Ethylenically unsaturated monomers containing at least two fluorine atoms, admixed if desired with another monomer, preferably halogenated, are polymerized in aqueous emulsion or dispersion, preferably in an alkaline medium, in the presence of an acid of the formula Cl(CF2-CX1X2)n-1CF2COOH in which X1 and X2 are fluorine or chlorine atoms and n is an integer from 2 to 16, or a salt thereof, and a polymerization catalyst, e.g. a redox system.  The process may be effected batchwise or continuously and the products may be liquids, waxes or solids.  The fluorine-containing monomer may be trifluoroethylene, chlorotrifluoroethylene, perfluorobutadiene, perfluoropropene, phenyltrifluoroethylene, alpha methyl phenyl difluoroethylene, perfluoroacrylonitrile, perfluorocyclobutadiene, tetrafluoroethylene, vinylidene fluoride, difluorodichloroethylene, or mixtures.  The other monomer may be vinyl fluoride, vinyl chloride, vinylidene chloride, or butyl acrylate.  The catalyst may be a mixture of sodium, potassium, or ammonium persulphate, or sodium perborate with sodium sulphite, hydrosulphite, metabisulphite, or thiosulphate.  Suitable buffers to give an alkaline medium are sodium tetraborate, orthophosphate, or acetate, or ammonium carbonate.  The acid emulsifier may be prepared as described in Specification 784,727.  The polymer may be freed from the emulsifier by coagulation with magnesium chloride which forms when hot a soluble magnesium salt with the emulsifier which can be removed by filtration.  The filtrate may be treated with acid to regenerate the emulsifier.

Abstract: 1468192 Automatic exchange systems INTERNATIONAL BUSINESS MACHINES CORP 24 June 1974 [16 July 1973] 27865/74 Heading H4K An attendance recording terminal is adapted to connect itself to a transmission channel for a predetermined time and includes means responsive to a signal from a processor which has responded to the connection and is acknowledging the reception of data from the terminal to maintain the connection beyond the predetermined time. The figure shows an attendance recording arrangement including a central recording processor 50 coupled to magnetic card reading equipment located at extensions of a P.B.X. The cards carry a single magnetic strip on which is recorded data relating to the user. With the exception of one character the code is a palindrome. Depending on whether the user is clocking in or out the card is fed into the reader with the appropriate end first and transported therethrough by hand. The first half only of the code is read. The data is decoded from duration modulated delta code to serial binary form, converted in a shift register 14 to serial by character, parallel by bit form and under control of a parity check circuit 40 and start and stop code detectors SOM and EOM and a buffer control 38 fed into a buffer 16. The end of message or stop code detector EOM triggers a monostable 44 to actuate a line loop relay for a predetermined time. If a go ahead tone is returned a detector 54 responds and the monostable is retriggered under control logic 56 and the characters are converted to multifrequency at 60 and transmitted to the central station. When correctly received an acknowledge tone identical to the go-ahead tone is returned to the extension and this again retriggers the monostable to allow for the immediate transmission of data from any further entered card and may operate an automatic door lock.

Title: Component for pneumatic systems

Abstract: 1502917 Valves; lubricating FISPA SpA 2 July 1975 [19 July 1974] 27919/75 Headings F2A and F2V [Also in Divisions B1-B2] A component for a compressed air system comprises, in a single assembly, an air filter, pressure reducing valve and a mist lubricator. Compressed air enters the assembly at an inlet 4, Fig. 2, in a central casing 1 and flows via passage 61 to the inner chamber 14 of a transparent plastic reservoir 8 screwed to casing 1. Vanes 22 swirl the air to cause centrifugal separation of the heavier particles which are collected at the bottom of chamber 14 for draining through valve 15. The swirling air then being deflected by plate 31 through a filter element 32 to passages 25 and chamber 24. Communication between the latter and a further chamber 39 is controlled by a pressure reducing valve comprising a closure piston 34 urged by spring 33 towards cylindrical seat 36 and in the opposite direction by a loading spring 55 acting on a piston 56 bearing on closure piston 34 via tube 58. Any increase in the pressure in chamber 39 causes piston 56 to move upwards to reduce the valve opening and thus restore the pressure to that set by loading spring adjusting knob 53. If the pressure increase is sudden, the valve fully closes and tube 58 unseats from piston 34 to vent chamber 39 to atmosphere via the. tube and ports 48. A major portion of the air flows from chamber 39 and past a resilient diaphragm 63 directly to the assembly outlet 5, the remainder flowing through inclined atomizing nozzle 77, Fig. 4, to mix with oil induced through passage 80 from a chamber enclosed by transparent dome 71. The air/oil mixture enters outer chamber 13 of reservoir 8 and thence flows through port 62 to outlet 5. Chamber 13 acts as an oil sump from which oil is drawn into dome 71 via a tube (64, Fig. 3, not shown), non-return ball (66), adjustable throttling needle (68) and tube 74. The sump can be filled by removing a plug (81, Figs. 1, 5, not shown). A gauge (84) indicates the output pressure.

Abstract: 183,077. Fraser, J., and Hennessy, M. Oct. 24, 1921. Valves actuated indirectly.-A barrel or cask is provided with a valve fitting which enables the flow of liquid to be cut off automatically when the usual tap is removed. The barrel 1 is provided with a threaded bush 2 which receives a hollow casing 3 perforated at 4<a>. A rotary plug 6 fits into the casing 3 and is perforated at 8 so that the two sets of perforations may be brought into or out of engagement by rotating the plug 6. The outer end of the plug is bored to receive the ordinary beer tap 9 which is secured by a bayonet-joint 12, so that when the tap is in position the perforations are in register and liquid may be drawn off. When the tap is detached, the plug 6 is turned by the bayonet catch so as to place the perforations out of register and thus close the fluid-passage.
