Patent GB-937367-A (GB)
Title: Apparatus for indicating the identity of a vehicle passing a given point
Inventor: RAYNER CHRISTOPHER STEPHEN
IPC: B61L25/04
Filed: 1961-06-28
Abstract: 937,367. Electric selective signalling systems. ROTAX Ltd. June 28, 1961, No. 23366/61. Class 40 (1). [Also in Group XXX] The identity of a vehicle passing a given point is entered into a shift register which is automatically cleared if the register receives an imcomplete signal. Each vehicle has 13 red reflectors 3 and 13 white reflectors 4 with a mask covering one or other of each pair so as to give the vehicle a coded identity. Blue-sensitive cells in a scanning unit 6 respond to the white reflectors only whereas red-sensitive cells respond to both red and white. The blue signals are fed to a shift register 9. The red signals are fed to a monostable multivibrator 13 which remains set while a vehicle is passing but returns after a delay if the registration is incomplete to restore the register 9. If the registration is complete restoration is inhibited by bi-stable multivibrator 15 which then also cuts-off the supply of blue and red signals. Several peripheral stations including a register 9 are connected over line 17 to a central recording station which scans the registers 9 in turn. The central station sends pulses characteristic of the wanted peripheral station over line 17 to be registered in shift register 20. A monostable multivibrator 23 restores register 20 in all peripheral stations except the wanted station in which preset diode matrix 25 reponds to cause an oscillator 27 controlled by a binary counter 30 to issue a stream of 13 pulses. If the register 9 has stored no signal multivibrators 15 and 33 are not operated and the 13 pulses pass over line 32 to appear on line 17 as a succession of O's. If the register is full multivibrators 15 and 33 operate so that AND gate 34 and OR gate 16 operate, whereby the vehicle number in shift register 9 is transmitted over lines 37 and 17. If the register is in the process of being filled, transmission along lines 32 and 17 begins before multivibrator 15 can operate so that 33 also fails to operate. Hence no signals appear on line 37 and filling of the register 9 is not affected by the transmission of 13 O's to the central station.

Title: Device and process for the even distribution of substances to be added to a viscous liquid especially a spinning solution and products manufactured therefrom
IPC: D01D1/06
Filed: 1949-09-09
Abstract: <PICT:0677081/IV (a)/1> A device for the even distribution of substances to be added to a viscous liquid, particularly to a spinning solution, comprises (1) a main closed supply circuit for the viscous liquid provided with the required connexions for supplying the liquid and the substance to be added and the discharge of the mixture, and a pump for the circulation of the viscous liquid, and (2) at least one secondary circuit with at least one circulation pump connected in such a manner that a part of the secondary circuit coincides with a part of the main circuit.  The pumps used are preferably gear-wheel pumps.  It is preferred to arrange that the flow of liquid in the branch or secondary circuit is opposite to the flow in that part of the main circuit which coincides with the secondary circuit.  Devices to remove entrapped air may be included in the various pipe lines.  All the lines and circuits and particularly the branch circuit may be heated or cooled if desired. The invention is applicable to all kinds of spinning solutions, to viscose, cellulose acetate, casein and artificial resins and to wet or dry spinning procedures.  The added substance should be finely divided, or dispersed or emulsified in a small quantity of the spinning solution.  Pigments (TiO2, carbon black), organic nitrogen compounds for animalizing the filaments, oils and fats and their derivatives, artificial and natural resins, latex and soaps may all be added.  As shown, the main circuit 11 feeds the branch lines 1, 2, 3, 4 and 5 leading to the spinnerets, and circulation of the solution in this circuit is maintained by pump 12.  The spinning solution, e.g. viscose, is led from a storage tank by line 13.  The auxiliary tank 14 holds a concentrated suspension in viscose of, for instance, carbon black which is fed by line 15 and pump 16 into the main circuit 11 which it enters in front of pump 12.  A secondary circuit 17 is attached to the main circuit and is provided with a pump 18. It is desirable that the quantity of solution circulating in the main circuit per unit time should be at least twice that consumed by the spinning machine, and that the quantity circulating in the branch circuit should be at least twice that in the main circuit per unit time.  A 5- or 6-fold excess in the branch circuit is preferable. Specifications 247,541, [Class 86], 248,046, 290,693, p  [both in Class 2 (ii)], and 393,934, [Group II], are referred to.

In the first potentiometric loop the potential D across the coil with respect to a point C, is amplified 32 and opposed by the potential from a D. C. 31 energized bridge 26, 27, 28, 29 which is adjusted by moving a wiper 31 until balance is achieved. In a similar way a wiper 40 of the second potentiometric loop is adjusted until balance is achieved but the second loop receives its reference potential from abridge 41 having a wiper 47 coupled to the wiper 31 of the first potentiometric loop. The system is for use in monitoring the temperature of a D. C. energized. motor, since temperature changes cause resistance changes.

Abstract: 764,181. Electrodialysis. HOOKER ELECTROCHEMICAL CO. Sept. 19, 1952 [Jan. 23, 1952], No. 23587/52. Class 41. A method of controlling molecular and ionic migration between the anode 7 and cathode 9 of an electrolytic cell when a voltage is impressed across the electrodes, comprises interposing a permselective membrane maintained wet with electrolyte between the electrodes, the membrane comprising a dried material substantially impervious to liquids and gases and having an ionized lattice structure maintained rigid by an immobile network of ions of one charge, the network permitting passage of ions of the opposite charge. In one example, a cationic permselective membrane separates anode and cathode, brine being supplied to the anode compartment and water to the cathode compartment, brine and caustic being removed respectively from the compartments which have outlets for gas. In another embodiment, two cationic permselective membranes A, B form a centre compartment 18 to which water is supplied and delivered by a conduit 17 to the cathode compartment 3. Membrane B may be porous. The cationic permselective membranes may be phenol formaldehyde ion-exchange resins or sulphonated copolymers of styrene and divinylbenzene in a polyethylene matrix, or asbestos paper soaked in such a resin which is subsequently further polymerized. In this case the membrane is wrapped round a steel cathode screen and a graphite anode employed. In the electrolysis of brine in the anode compartment and sodium carbonate in the cathode compartment using a single cationic permselective membrane carbon dioxide may be supplied to the cathode compartment, where sodium carbonate is formed. An anionic permselective membrane may be interposed between the cationic membrane and the anode, e.g. in the electrolysis of sodium sulphate solution to produce sulphuric acid, the sodium sulphate solution being supplied to the centre compartment and the electrode compartments containing water. One at least of the electrodes may contact a membrane. Current densities of 60 to 90 amps. per square foot of membrane and voltages of 3.7 to 4.4 are mentioned.

Abstract: 913,563. Numerical control of machine tools. INDUCTOSYN Ltd. July 7, 1960 [July 16, 1959], No. 23763/60. Class 38 (6). In a programme controlled drilling-machine or jig-borer, a signal is provided when the worktable is stationary and at the required position. The motor 1 drives the table in response to A.C. positioned error signals applied at 2. These signals are also applied via an amplitude limiter 11 and rectifier 21 to the operating coil 14 of a first relay 55 so as to hold the contacts open. A velocity signal is obtained from a tachometer 5 (or a differentiating network) and applied via limiter 10 and rectifier 20 to the operating coil 13 of a second relay 54. When both signals are zero, i.e. no positional error and no movement, the upper contacts 24, 26, 34, 33 of both relays are released, and close, thereby energizing booster coils 43, 44 which ensure that all the contacts are firmly closed. This also energizes a relay 7 over contacts 23, 25 and this provides the required signal. A switch 52 controlled by the programme source de-energizes the booster coils 43, 44 so that coils 13, 14 can again assume control. Specification 807,219 is referred to.
