A wound capacitor has electrodes 13, 14 projecting from opposite ends of the winding 12, and electrical contact is made with electrodes 13, 14 by metallic end plates 15, 16, provided with radial grooves or hollows 18 which allow drying and impregnation of the capacitor when the end-plates are in place. Winding 12 is on an insulating core 11 e.g. of resin-bonded fibreglass, and the electrode foils are interrupted every few turns to reduce the inductance of the capacitor. A layer of wire gauze 211 or other springy material is disposed between plates 15, 16 and electrodes 13, 14. Terminals 21, 22 are threaded on to core 11 and contact plates 15, 16. An insulating casing 25 projects endwise beyond plates 15, 16 which are sealed in position by insulating material 29 e.g. epoxy resin. Casing 25 may be a tube of resin-bonded fibreglass, or may be formed by a number of windings of impregnated fibreglass sheet. Eyelets 28 communicate with the interior of the capacitor through space 24 and holes 20 in grooves 18 and are sealed off after impregnation. In the capacitor of Fig. 4 core 11 is tubular and a conductor 36 is sealed therein by a polymerized resin 37 preferably having the same dielectric constant as the core.

Title: Improvements in or relating to magnetically operated apparatus in traffic control systems
IPC: B61L1/16
Filed: 1953-08-10
Abstract: 730,359. Track and train interacting apparatus. SIEMENS & HALSKE AKT.-GES. Aug. 10, 1953 [Sept. 1, 1952], No. 22047/53. Drawings to Specification. Class 105. In apparatus such as axle counters operated by change in magnetic flux due to relative movement between an element carried by a vehicle and a stationary element in the path of the vehicle, one of the elements comprising a magnetic mass and the other comprising two oppositely . directed permanent or electromagnetic devices disposed to encounter the said mass in overlapping successive periods, the magnet pole first encountered by the mass has the same polarity as the earth's magnetic field at the location of the encounter. For example, in the Northern Hemisphere, a pole of the stationary magnets on a track to be encountered first by the axles of a train would be a south pole and in the Southern Hemisphere, a north pole. By this arrangement the overlapping period in which the two devices of the apparatus are both in the operated state is prevented from being too large a proportion of the period from the start of the one device to the ending of the other device. The variation in flux may be used to control electrical contact mechanisms or the impedance of a choke whose impedance variations are used for remote control purposes. The arrangement of the magnets may also be used for applying an influence from the track to the train.

Abstract: 1516987 Automatic control of fuel supply to IC engines ROBERT BOSCH GmbH 22 May 1975 [5 Dec 1974] 22163/75 Headings G3N and G3R [ Also in Division F1] The fuel fed to a mixture compressing, sparkignited engine is controlled by a computing circuit, the position of the throttle valve of the engine and the engine speed being monitored and signals resentative thereof being fed to the computer which provides an output signal for coarse regulation of the fuel/air mixture, the signal being determined by a set of characteristic curves stored in the computer and also being modified, for fine regulation of the fuel/air mixture, by monitoring an operating variable of the engine and adjusting the signal in dependence thereon. An injector 6 is provided adjacent the inlet valve of each cylinder of engine 2 and the quantity of fuel injected into the induction pipes is determined by computer 8 which controls the duration of injection. The position of throttle valve 5 is indicated by potentiometer 9 and the speed of the engine by pick-up 12. Stored in computer 8 is information concerning the appropriate duration of injection at various engine speeds for each of a number of angular positions of throttle valve 5, Fig. 2. This information is retrieved and provides the coarse regulation of the mixture. Fine regulation is achieved by using the signal from an exhaust gas composition sensor 17 which is used to modify the control signal provided by computer 8 so that the mixture is maintained at the stoichiometric ratio or there is a slight excess of air. The pick-up 12 can also be used to detect irregular running of the engine and the unit 16 is biased so that when irregular running is detected, the correction which is applied produces a leaner mixture rather than a richer mixture.

Abstract: 1339301 Casting processes F KOCKS 19 April 1971 [2 March 1970] 22221/71 Heading B3F In a method in which ingots are cast and subsequently processed one after the other, they are cast in a chronological sequence at time intervals corresponding to the cycle time of the processing step. The melt is supplied from a smelting furnace to a heated vessel from which it is poured into the moulds at predetermined intervals of time. The said vessel holds enough metal to cast a plurality of ingots and is refilled from the furnace before it has been completely emptied, the heating being interrupted before the refilling so as to allow the new batch of metal to cool to the pouring temperature. Two or more smelting furnaces may be provided for each vessel if the time required for charging the furnace is longer than the sum of the casting intervals in each casting cycle, i.e. the time interval between filling of the said vessel and the removal of the last ingot portion therefrom. Conversely, two or more vessels may be refilled from the same furnace if the charge time is substantially less than the length of a casting cycle. An example describes the production of ingots at 15 minute intervals using a vessel having a capacity equivalent to five ingots.

Abstract: 767,481. Making tubular elements; forging. HUET, A. Sept. 24, 1951 [Sept. 22, 1950; Feb. 19, 1951; Feb. 26, 1951], No. 22277/51. Classes 83 (2) and 83 (4). A method of manufacturing a tubular metal element comprises obtaining a concentric bulb on a tube by axial compression, and then shaping in a semi-cylindrical die so as to render the bulb eccentric without substantially increasing the thickness of the wall of the tube, causing material of the tube wall at the location of the bulb to pass from one sector of the tube towards the opposite sector. An axial swelling b, Fig. 1, is formed on a tube a, e.g. by upsetting in an electrical upsetting-machine and the swelling displaced to form the eccentric bulb b<SP>1</SP> by forging with internal mandrel C, the bulb being completely or partially heated. The bulb may then be opened, Fig. 4, to form a connection for a pipe whose diameter D may be greater than the diameter d of the tube a. The tube may be bent, Fig. 8, and the bulb b1 may be pressed back to provide a bend with a thick external wall, Fig. 9. In a modification, Figs. 11 and 12, the axial bulb is displaced in a die to form an internal projection p in the tube, and opened to form a connection f. The eccentricity of the bulb may be accentuated by axial electrical upsetting before opening. In a further modification. Fig. 17, a punch k is introduced into the connection f and the tube axially upset to size the connection I around the punch. Angular bending.
