Patent GB-1289348-A (GB)
IPC: H04Q11/04
Filed: 1969-08-28
Abstract: 1289348 Automatic exchange equipment STANDARD TELEPHONES & CABLES Ltd 18 Aug 1970 [28 Aug 1969] 43000/69 Heading H4K In a TDM telephone exchange system each digit of a wanted outsinks number is sent in the form of a five element code and is repeated at least once. Each element is sent as 8 bits and the received bits are put into counter BC with all 1 bits being put additionally into majority decision counter MDC. After the 8 bits representing one element of a code have been received in counter BC the output of counter MDC is stored in shift register CASR which is then incremented by the resetting pulse on BCO which also resets counters MDC and BC ready to receive the bits of the next element. Counter CAC is a five element counter which is incremented by the pulse on BCO so that after five elements have been received it is recognized, by the presence of an output from CAC, that a digit is now stored in CASR. The contents of CASR are shifted into store PCR so that register CASR can be filled with the next five elements received. The elements stored in CASR and PCR are compared in the 5 bit comparator COMP and, if identical, cause the digit to be inserted in the telephone exchange register when a code for an interdigital pause is received.

Abstract: 1290161 Antiskid braking systems AISIN SEIKI CO Ltd 13 Oct 1969 [11 Oct 1968 16 Nov 1968] 50277/69 Heading F2F  In a method of controlling the maximum fluid braking pressure in an antiskid vehicle braking system the prevailing coefficient of adhesion between the wheels and road surface in a sudden brake application is determined as a value of vehicle deceleration, the value of said coefficient in terms of deceleration is preserved in a memory means, the braking pressure is increased to a predetermined value corresponding to an impending wheel lock and the brake applying pressure is released under the control of the said stored coefficient value in the memory means, the rate of release of the brake fluid pressure being made slower when the sensed vehicle deceleration is larger. A conventional master cylinder assembly 10 is connected to front wheel brake cylinders 14a, 14b, to an inlet port 28 of oil pressure control mechanism 17 fitted with a pneumatic servo-mechanism 16 and to a valve assembly 40 via a vehicle deceleration sensor 99, the rear brake cylinders being connected to a port 25 of mechanism 17 which latter is fitted with a pneumatic servomechanism 16 comprising a diaphragm piston 20 which divides a housing 34 into chambers 21, 22 and is backed up by a return spring 32, the diaphragm being kept in pressure contact with a plunger 23 slidable in cylinder 103 of the mechanism 17, and having an extension 29 which can keep a ball 30 away from a valve seat 33. Chamber 21 is kept in communication with a vacuum source such as an engine intake manifold 37 while chamber 22 is normally kept in fluid communication with the same vacuum source 37 through a conduit 39, a valve assembly 40 and conduits 36, 41. The valve assembly 40 comprises a housing 44 connected through a conduit 43 with the sensor 99 and containing a solenoid coil 46 and a spring-urged armature 47 carrying a valve member 48. The coil 46 is connected to a battery 59 via a switch 56 in a computer 55 connected to a conventional skid sensor 60 which senses an impending or actual wheel lock. The deceleration sensor 99 comprises a slidable stop member 65 between springs 66, 76 in a housing 61 and a movable rod 68 having a cup 110 which with the member 65 divides the housing into two chambers, said rod co-operating with a pendulum 70 and being engaged by a oneway clutch assembly 78 which acts as a memory. The cup 110 forms a valve with a seat member 64 to control the entry of atmospheric air and thus the pressure difference applied to piston 20, this also being controlled by valve 40 in response to the sensor 60.

Abstract: 1311850 Liquid seals RUBBER & PLASTICS RESEARCH ASSOCIATION OF GREAT BRITAIN 4 May 1970 [6 May 1969] 23003/69 Heading F2B A liquid seal for maintaining a pressure difference between zones at different pressures during transfer of a continuous product, such as an electrical cable 18 between the zones, comprises means for maintaining the liquid (e.g. water) in the space between the product and the interior surface of a transfer tube 16 and means for creating turbulence in the liquid. The sealing water passes from a pipe 11, Fig. 2, which acts as a reservoir, to a pipe 13 under the influence of the pressure difference, the water then being re-circulated back to the reservoir pipe 11  by a pump. The pipe 11 may be inclined and connected at its upper end to a heated fluidized bed. On leaving the fluidized bed, the cable 18 passes down the pipe 11 and beneath the level of the water therein. The transfer tube 16 is interchangeable and is mounted by quickrelease clamps 14. The turbulence in the sealing water may be created by pressurized air which is supplied through an inlet 21 in a chamber surrounding the transfer tube and directed by angled bores 19 and radial bores 20 into the water. In a modification, Fig. 6, the turbulence is created mainly by helical inserts 22, 23 which impart a helical motion first in one direction and then the other as the water passes through the transfer tube; in this embodiment the radial air bores are omitted. If desired, the transfer tube 16 may be rifled instead.

Abstract: 1316692 Explosive and propellent compositions NORTH AMERICAN ROCKWELL CORP 4 May 1970 21426/70 Heading ClD [Also in Divisions C2 and C3] A polymer of a compound of the formula where R is alkylene of 1 to 4 carbon atoms (see Division C2), is used as an energetic binder in explosive and propellent compositions. Prepolymerization of the monomer may be carried out using a Lewis acid catalyst and a hydroxygroup-containing initiating compound. The compositions also contain an oxidizing agent, a fuel, a curing agent, and bis-(2-fluoro-2,2-dinitroethyl) formal as an energetic plasticizer. The fuel may be powdered boron, Al, Mg, Be, or alloys of Al-B, Al-Mg, or Al-Cu, and the oxidizing agent ammonium, alkali metal, or alkaline earth metal salts of nitric, perchloric, or chloric acid. Various di- and poly-isocyanates are specified as suitable curing agents. Examples describe the preparation of propellent compositions in which aluminium powder is used as the fuel, ammonium perchlorate as the oxidizing agent, polymethylene polyphonylisocyanate as the curing agent, and ferric acetonyl acetate as a curing catalyst. Higher density impulse figures are obtained by using hydroxylamine perchlorate in place of ammonium perchlorate.

Abstract: 1318037 Cathode-ray tube circuits IMAGE ANALYSING COMPUTERS Ltd 28 Sept 1970 [31 Oct 1969] 53402/69 Heading H4T To analyse a large number of specimens in rapid succession the frame scan rate is increased, e.g. doubled, during the erase intervals in order to reduce the time required to remove the residual charge pattern left at the end of each read-out scan in a television camera, e.g. a "Plumbicon" (Registered Trade Mark) having a fast internal time constant photosensitive layer. With the frame scanning rate doubled during the erase interval it is desirable to simultaneously increase the spot size to compensate for the number of horizontal lines in the raster being halved, and this may be effected by altering the focus of the electron beam. A further improvement may be obtained by simultaneously increasing the line scanning rate and the beam current during the erase intervals, and where the same multiplying factor is applied to both line and frame scan rates it is not necessary to increase the spot size but only the beam current to compensate for the increased line scan rate. Preferably the video output from the camera is blocked during each erase interval.
