Title: Fluid pressure control valve
IPC: B60T8/18
Filed: 1961-12-13
Abstract: 946,630. Fluid-pressure servomotor systems. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Dec. 13, 1961 [Dec. 28, 1960], No. 44692/61. Heading G3P. [Also in Division F2] A motor vehicle having a spring suspension is provided with a levelling valve 174 fixed to the axle 182 of the vehicle and actuated by a lever 188 connected to a piston 180 of a cylinder 178 fixed to the vehicle frame 190. Source pressure in a pipe 184 is directed by the levelling valve through a choke 173 to the piston 180 and through a second choke 170 and an auxiliary reservoir 166 to a spring-biased piston 140 carrying, for purposes of adjustment, an exhaust valve seat 152 of a brake valve (see Division F2). The arrangement is such that increased vehicle loading bleeds the auxiliary reservoir through the levelling valve 174, hence allowing the exhaust valve seat to rise until the levelling valve is nulled by a corresponding rise of the piston 180. The exhaust valve seat is thus positioned in accordance with the vehicle loading. The seat may also be made manually adjustable.

Title: Improvements relating to non-continuous signalling systems
Inventor: DUCKITT HARRY
IPC: B61L3/12
Filed: 1962-11-30
Abstract: 989,038. Automatic train control. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Nov. 20, 1963 [Nov. 30, 1962], No. 45355/62. Heading B7N. An arrangement for signalling between a point on a railway track and a passing train comprises a pair of coils 7, 8, which are spaced apart along the track and tuned to particular different frequencies by choice of capacitors C1-C8, an amplifier on the train with input and output coils which are coupled when passing each trackside coil whereby the amplifier oscillates at the frequency to which the trackside coil is tuned, decoding means connected to the output of the amplifier for initiating a signalling or like operation on the train defined by the frequencies of the two output signals from the amplifier and alarm means which are brought into operation if on passing a signalling position on the track only one or more than two signals are produced by the amplifier. The integrity of the amplifier is continuously checked by a coil 5 and capacitor 6 on the train tuned to a pilot frequency which loosely couples coils 3 and 4 and provides a low level output from the amplifier which is monitored by a circuit which in the absence of a signal operates the alarm means. The output of the amplifier is connected to a number of tuned filters-filters F1-F4 in group X each set to one of the frequencies to which trackside coil 7 can be tuned, filters F5- F8 in group Y are each set to one of the frequencies to which coil 8 is tuned and filter F9 is tuned to the pilot frequency. Each filter is connected to a magnetic storage device M1- M9 which when energized by a signal via its respective filter provides an output to operate an associated relay R1-R9. Relays R1-R8 are provided with repeat relays R1P-R8P, contacts of which are disposed such that on receipt of one signal in each of groups X and Y one of the circuits A-Q is energized to produce signalling operation or the like on the train. A slow release alarm relay AR is normally energized to prevent operation of the alarm via back contacts of relays R1-R8 and a front contact of relay R9 which is normally energized by the pilot tone. On passing a signalling position, the increased coupling between coils 3 and 4 produced by the trackside coils prevents generation of the pilot signal and relay R9 releases, the alarm relay is now de-energized but if one signal is generated in each of the groups X and Y, one repeater relay in each group picks up and the alarm relay is re-energized before its delay expires via a circuit which includes a front contact of one of the repeater relays in each group and a back contact of relay R9. If two or more signals are received in one group all the repeater relays in that group would be de-energized, as they would be if no signal is received, in each case the relay AR would not be re-energized and the alarm circuit would be operated.

Title: Electrical translator with a learning character for non-binary signals
IPC: G06V30/194
Filed: 1962-11-30
Abstract: 958,453. Learning circuits. STANDARD TELEPHONE & CABLES Ltd. Nov. 30, 1962 [Dec. 7, 1961], No. 45363/62. Addition to 939,134. Heading G4R A learning circuit for identifying a waveform signal Fig. 1 represented by a series of sample values ai1-ai n, consists of a series of input column leads A1 - An, Fig. 2 for the sample values and a series of row leads B1-Bm there being coupling members at each cross point whose physical condition is changed during the learning phase by the action of input sample values and a signal on a corresponding row lead so that during a subsequent recognition phase the applied pattern will cause a maximum signal on the corresponding output lead. The coupling members may be torroidal ferrite cores and two column wires 1, 2 Fig. 5 pass through each core together with the row wire. In the learning phase a high-frequency A.C. current is applied to a row wire which induces a voltage in the column wires 2 of each core whose amplitude and phase indicates the state of magnetisation of the core. These are compared at V u  with the A.C. voltages and the difference is used, together with the current in the row wire for changing the magnetisation of the cores. The generator G is coupled to the row which is to be set by closing one of the switches B1-Bm. The signal generated by any core on that row is now, after conversion in a converter W, compared with the corresponding input value aiu and the difference applied to a regulator R u  for application to the other column wire 2. The current in the row wire is at a frequency of half that of the input on the column wire. Owing to the non-linearity of the cores, a double frequency component appears in the core output and it is this component which is compared with the input by being suitably phase-shifted and added or subtracted to obtain a difference. The difference signals amplified at R1-Rn add their effect to the cross wire current to cause a series of small adjustments to be made to the magnetic state of the cores until the output exactly balances the input i.e. the difference has fallen to zero. In the recognition phase each input signal on column wires 1 produces an output on all the row wires, the output from any particular core being dependent on the amount of magnetisation set into it. The arrangement is such that the coupling provided by each core is proportional to the corresponding amplitude sample of the patter which that row of cores is designed to recognise. A single column wire may be used, the two signals being separated by filters. Instead of cores the coupling elements variable capacitors or electrolytic devices may be used. For waveforms which may become negative the matrix may have double columns, one for positive signals and one for negative values, the two output signals having an opposite phase relationship.

IPC: G01C13/00
Filed: 1965-09-07
Abstract: 1,128,500. Determining temperature/depth relationship. BUZZARDS CORP. Sept. 7, 1965. No. 46025/67. Divided out of 1,126,381. Heading G1N. Apparatus for determining the relationship between temperature and depth of water contains means for initiating the measuring cycle when a probe, launched from a ship, touches the surface of the water. The system is prepared by operating switches 148 and 51 (Fig. 2) whereby relays A, B and C are energized. A 'LAUNCH' signal is transmitted via the changed-over contacts, and when the probe strikes the water a path is completed between an electrode 155 on the probe and an electrode 190 on the ship, causing transistor 152 to conduct. This short-circuit relay A which falls, followed by relay B, whereupon a recorder chart is driven, and relay D is energized to connect the thermistor R56 into a bridge circuit, whose unbalance is amplified at 122 and fed to the recorder. The resistance of the two-wire cable connecting the thermistor to the bridge is represented by resistors R60, R62 in adjacent arms of the bridge, substantially compensating for their change in resistance with temperature. Before launch, the system is calibrated for several discrete temperatures by selecting one of the predetermined resistors 140, 141, 142 to replace the thermistor R56 in the measuring bridge. In a modification a 3 wire cable links the probe to the measuring circuit, and the electrodes 155, 190 are only used to initiate the measuring cycle.

Patent GB-1002150-A (GB)
Title: Method for preparing dialkyl esters of dicarboxylic acids
IPC: C25B3/23
Filed: 1962-12-11
Abstract: Di-alkyl esters of dicarboxylic acids are formed electrolytically from the alkali salt of a mono-alkyl di-carboxylate, by passing the solution of the alkali salt in neutral or slightly acidic condition into the anolyte zone of an electrolytic cell having a cationic permeable membrane separating the anode and cathode zones, the catholyte being kept alkaline. The di-ester is formed by anodic oxidation, and forms an oily layer on the anolyte and after extraction with hexane is distilled.  A 25-35% solution of the salt in water or a lower alcohol is used as anolyte.  The catholyte is 0.5-3% aqueous solution of alkali metal hydrate, carbonate, or bicarbonate.  The monoesters are derived from alcohols containing 1-3 C atoms and di-carboxylic acids of 3-13 C atoms, e.g. malonic, glutaric, adipic, azaleic, and brassylic acids.  Mixtures of these may be used to form, e.g., methyl propyl sebacate, methyl thapsiate, and dimethyl-3-ethyl-n-tridecani di-carboxylate.  The cationic membrane may be homogeneuos or heterogeneous, e.g., polystyrene sulphonic acid, divinyl benzene methacrylate, divinyl benzene maleic anhydride. Preferably the cell has a central anode zone and a cathode zone on each side.  After separation of the di-ester from the anolyte it is recycled after adjustment of pH value at 6-7. Water is added to the catholyte to maintain the alkali concentration at required level. A voltage of 9-13 V. and 20 A. is applied.
