Title: Improvements in or relating to communication systems
IPC: H04Q3/00
Filed: 1961-09-29
Abstract: 995,632. Automatic exchange systems. SIEMENS & HALSKE A.G. Sept. 29, 1961 [Sept. 30, 1960], No. 35279/61. Heading H4K. An arrangement for detecting the flow of current when a subscriber's line is looped comprises a transformer U1 having an iron core with a rectangular hysteresis loop, two input windings e1, e2 connected between the poles of the exchange battery and the subscriber's line transformer U2 as shown in Fig. 1, a bias winding v carrying sufficient direct current to hold the core in one magnetic state (working point A1, Fig. 2) when no loop current is flowing, a winding f which receives pulses of current i (Fig. 2) which tend to drive the working point further into the one magnetic state and an output winding a. When no loop current is flowing the pulses on winding f produce no significant output in winding a but on closure of the subscriber's loop the state of the core is shifted to point A2 due to the current in windings e1, e2 and consequently when winding f is pulsed, two pulses appear in the output winding due to the transition from A2 to A1 and back to A2. The insertion loss of the arrangement may be reduced by connecting a winding of a choke between each of the windings e1, e2 and the line transformer U2. The scanning winding f may be replaced by two windings which form part of a row and a column in a matrix of such windings.

Title: Improvements in process of making key bolts
IPC: B21K1/44
Filed: 1920-12-16
Abstract: 173,161. Withers, J. S., (Northey, J. P.). Dec. 16, 1920. Bolts.-A slotted key-bolt,. of the form shown in Fig. 5, is made by bending a bar of uniform cross-section upon itself and upsetting the free ends to form a shank and head. The bending is effected by the descent of grooved rollers 2, Fig. 1, by which the stock 14 is bent round a mandrel 1, as shown in dotted lines. The work 7, Fig. 7, is then placed in a die 5, formed in halves, and the free ends are upset in a single operation, or in two operations by dies 9, 10. Closure of the slot during upsetting is prevented by a slightly tapered form 6 on each half of the die. The bottom of the slot in the bolt is thus formed with a slight curvature, so that a key can be inserted from either side. Flats are formed on the blank during the bending to prevent the formation of fins between the halves of the die during upsetting.

Title: Improvements in or relating to television apparatus
IPC: H04N5/20
Filed: 1957-11-21
Abstract: 859,127. Television. FERNSEH G.m.b.H. Nov. 21, 1957 [Nov. 21, 1956], No. 36274/57. Addition to 856,936. Class 40(3). In a television signal "gamma", control system of the type described in the parent Specification in which only the lower-frequencies are subjected to non-linear amplification by supplying the total signal via a low-pass filter to the non-linear amplifying device the output from which is then combined with the complementary-frequency positions of the total signal to form the required "gamma" corrected signal, non-linear distortions in the latter signal are reduced by interchanging the positions of the low-pass filter and the non-linear amplifier so that the total signal is first subjected to non- linear amplification and then passed through the low-pass filter before being combined with the complementary-frequency portion of the total signal. This arrangement is shown schematically in Fig. 3 where 3 represents the non-linear amplifier, 2 the low-pass filter and 4 a high-pass filter the characteristics of which is complementary to that of 2. In a modification of this arrangement which allows the characteristic of the "gamma" corrector to be varied, Fig. 5, the latter consists of the combination of a "gamma" amplifier 12 (γ = 0À4) and a linear amplifier 13 of equal gain the outputs of the two being combined in potentiometer 18 so that a signal having any desired degree of correction to the maximum (γ = 0À4) may be supplied via the lowpass filter 14 to a combining circuit 16 to which is also supplied the output of the complementaryfrequency high-pass filter 17. A subtraction circuit of the kind described in the Specification may be employed in place of the filter 17.

Title: Electrical power plant with pump turbine
Inventor: LAUBE GOTTERIED
IPC: F03B13/06
Filed: 1964-09-04
Abstract: 1,076,419. Motor/generator driving arrangements. VEB. ENERGIE PROJEKTIERUNG. Sept. 4, 1964, No. 36301/64. Heading H2A. [Also in Divisions F1 and F2] A power plant comprises a pump-turbine 3 which runs in a different direction and at a different speed when acting as a pump than when acting as a turbine, connected through a gear-box 2 to an electrical machine 1 which runs in the same direction and at the same speed when acting as a motor and when acting as a generator. The gear-box 2 comprises a dual hydraulic coupling having two output members 7, 8 and a common input member 6, the latter being connected to the shaft of the pumpturbine 3. The gear-box 2 also comprises a planetary gearing 5 having a stationary annulus gear and a rotating planet carrier, the latter being connected to the output member 7. A further gearing 4 is similar to the planetary gearing 5 but has a stationary planet-carrier and a rotating annulus gear, the latter being connected to the output member 8. The central or sun gear of each gearing 4, 5 is connected to the shaft of the electrical machine 1. For turbine-generator operation, coupling. 6, 7 is filled with oil and the drive is transmitted through this coupling and the step-up gearing 5. For motor-pump operation, coupling 6, 8 is filled with oil and the drive is transmitted through the step-down reversing gearing 4 and this coupling. Changeover from one type of operation to the other is effected. without stopping the electrical machine 1 or altering its speed, by emptying one coupling and at the same time filling the other coupling. This brakes the pump-turbine hydraulically to rest and sets it running in the opposite direction. The pump-turbine does not have to be emptied of water during the changeover. If both couplings are emptied to disconnect the pump-turbine from the electrical machine, the latter continues running but functions as a synchronous condenser for improving the power factor of the system. The hydraulic couplings may be located adjacent the electrical machine 1 instead of the pump-turbine 3 and may be of torqueconverter type. The heat due to losses in the electrical machine, gearing and hydraulic couplings can be used in a common recuperation plant.

Abstract: Vinyl chloride is polymerized alone or with vinyl acetate in an aqueous medium in the presence of at least 0,02% by weight, preferably 0,1 to 7%, of the monomer or monomers to be polymerized of a cetyl trimethyl ammonium salt to produce a product having good antistatic properties which may be used for gramaphone records.  The cetyl trimethyl ammonium salt may be added in one step, in a number of steps or continuously during the polymerization after the initial introduction.  The preferred catalysts for the polymerization are peroxy compounds.  Antifoam agents and common additives such as plasticizers may be added. The polymers produced may be compounded or blended with other polymeric materials.  In the example vinyl chloride is copolymerized with vinyl acetate in the presence of cetyl trimethyl ammonium bromide, silicone antifoam agent, hydrogen peroxide and distilled water.
