Patent GB-439283-A (GB)
Title: Improvements in or relating to electric carrier signalling systems
IPC: H04J1/16
Filed: 1935-01-16
Abstract: 439,283. Two-way transmission. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, SMART, N. C., and WESTELL, E. P. L., c/o General Electric Co., Stoke, Coventry. Jan. 16, 1935, No. 4761 /34. [Class 40 (iv)] [See also Group XL] In a system in which carriers f1, f2 may be interrupted at definite frequencies for signal purposes, but are otherwise continuously transmitted from B to A and A to B, respectively, over, for example, a power circuit 1, and in which failure of either carrier results in the disconnection of the other so that an alarm is given at each station, faulty operation of the alarm in response to the signalling interruptions is prevented by the provision of two relays, one L maintained operated by the uninterrupted or slowly-interrupted carrier and the other MC by the carrier when rapidlyinterrupted at signal frequency. On the failure of the incoming carrier, the release of both relays releases relay CF which closes the alarm circuit and disconnects battery from the modulator M to cut off also the outgoing carrier. Specification 381;620, [Group XL], is referred to.

Filed: 1943-03-25
Abstract: 564,443. Temperature responsive actuating elements. STILWELL, JUN., W. E. March 25, 1943, No. 4845. Convention date, March 12, 1942. [Class 64 (ii)] [Also in Group XXXVII] Contacts 24, 39 and 25, 40 in a load circuit, such as used in house or industrial wiring systems, are closed or opened by energizing a coil 33 or 32 respectively from a low volt circuit of, say, 6 to 50 volts and thereby moving a rod 36 down or up with a snap action produced by a buckling spring 35; the contacts 39, 40 are mounted on a bimetal member 38 which on overload snaps up into the dotted position, breaking the load circuit. The bimetal member is such that on cooling it either snaps back again or, in a modification, remains in the dotted position. In the latter case,'the switch is reset by energization of the coil 32 which will force the bimetal member into its down position. The switch can then be closed as before by energizing coil 33. The snap spring 35 consists of arim connected by spokes to a centre portion. The bimetal member also has spokes.

Abstract: 625,764. Fluid-pressure servomotor control systems. DOWTY EQUIPMENT, Ltd., and SNELL, M. S. Feb. 24, 1947, No. 5367. [Class 135] [Also in Groups XXXIII and XXXVIII] The valves 32, 33 of a hydraulic jack, actuating, e.g., an aircraft wing flap, are controlled directly or with the aid of relief relays 48, 55 by a polarized relay 36 connected between the sliders of potentiometers 37, 38 driven respectively by the control lever 29 and the flap 27. In the application shown, the valves 34, 35 of a jack 31 controlling a second flap 28 are normally operated in parallel with the valves 32, 33. If, however, the flaps fall out of alignment, a polarized relay 41 connected between the sliders of potentiometers 39, 42 driven by the respective flaps is actuated and energizes either the relay 52 to disconnect the valves of jack 30 or relay 54 to disconnect the valves of jack 31, according as the flap 27 is ahead of or behind the flap 28, in the direction of the adjustment. The valves may be of the kind described in Specification 544,340. The ratio of the angular movements of the flap and the control handle need not be unity, and the potentiometer circuits may be adjustable to vary the limits of the range of movement. Movement of the control lever 29 may be used to energize the potentiometers.

Title: Improvements in or relating to the colouration of textile materials made of or containing cellulose esters or ethers
IPC: D06P1/649
Filed: 1931-02-20
Abstract: Cellulose esters or ethers, dyeing; textiles, treating with liquids; dye preparations.--The fastness of colourations on textile materials made of or containing organic esters or ethers of cellulose, particularly the fastness to the combined action of light and acid of colourations with anthraquinone dyestuffs containing amino, alkylamino or arylamino groups, is improved by applying thiourea to the materials before, during or after their colouration and retaining it in the materials during any subsequent finishing treatment.  A further improvement in the fastness may be obtained by simultaneous or separate application to, or incorporation in, the materials of compounds having an alkaline reaction, e.g. borax, sodium carbonate, disodium hydrogen phosphate, sodium acetate, sodium palmitate or potassium oleate. Other substances adapted to increase the fastness of colourations may be employed with the thiourea, e.g. the substances used for this purpose according to Specifications 243,841, [Class 15 (ii), Dyeing, Processes &c. for], 340,541, 340,572, 355,726, or 361,362, or organic amines wherein an amino group is not attached directly to an aryl nucleus, e.g. mono-, di- and tri-benzylamines, monobenzylmethylamine, dibenzylmethylamine, dibenzyl - o  - oxyethylamine, primary or secondary octylamine, amino derivatives of cycloparaffins, or compounds obtainable by the action of ammonia on halogenated higher aliphatic hydrocarbons may be employed with the thiourea.  The thiourea may be applied in solution in water, alcohol or other organic solvent and up to 2 per cent may suitably be present in the finished material.  It may be incorporated in dye preparations with or without dispersing agents and/or protective colloids.  The following examples are specified: (1) A knitted cellulose acetate fabric dyed blue with 1 : 4 - di(methylamino)anthraquinone is impregnated in a bath containing 6 cc. per litre of sulphonated castor oil and 2 per cent of thiourea, and is centrifuged and dried.  (2) A woven cellulose acetate fabric is dyed, padded in a bath containing per litre 2 grams of thiourea and 2 grams of borax, pressed to expel the excess liquid, dried and finished.

Title: A relay system for measuring the time of the continuous flow of an electric current
IPC: H04L25/04
Filed: 1936-02-22
Abstract: 475,954. Current duration meters; electric signalling systems. WATANABE, Y. Feb. 22, 1936, No. 5408. Void. Convention date, June 8, 1935. [Class 37] [Also in Group XXXVIII] In a relay system for measuring the time of flow of an electric current, a main relay f is energized throughout the time of flow of the current, and the relays of a primary series of time-limit relays a ... e are operated successively and continuously during this time, while the relays of a secondary series A ... E are operated one by one every time the last relay e of the primary series is operated. The time-limits of the relays a ... e are controlled by a resistance R and when the relay a operates, it closes its switch 3 whereby the circuit of the relay b is completed. This operates after its time-delay period to open a switch 2 which resets the relay a and close a contact 1 in a hold-in circuit and a contact 3 which completes the circuit of the relay c. The relays c, d, e are similarly energized, and the relay e closes a contact 4 in the circuit of the first relay A of the secondary series. This series may be constituted by instantaneous relays and each is provided with a contact S which is connected to an indicating and recording device and which is closed when the appropriate relay operates. The relay A when energized opens a contact 2 and closes further contacts 1, 3, the former of which is included in a hold-in circuit and the latter of which is in the circuit of the relay B. This circuit is completed at the next operation of the relay e and serves to close the switch for the relay C and open a contact 8 to reset the relay A. The relays C, D, E, are similarly operated but the relay E when energized continues to operate, even while the relays A, B &c., are again operated. In a modification, two end relays such as e are provided which are operated alternately at the end of the operation of the primary relay series. One or other of these relays is rendered operative according to the state of a further auxiliary relay ; if this is energized, one of the alternative relays is operated, and if de-energized the other relay is operated. The auxiliary relay is controlled by the relay d and when energized remains in operation until the relay c is energized during the next cycle of operations. In this modification, the relays A ... E when once operated remain in operation. A further series of relays may be provided similarly controlled from the series A ... E.
