Patent GB-359410-A (GB)
Abstract: 359,410. Electric signalling arrangements. WATTS, A., 10, Cambridge Road, Bromley, Kent. July 17, 1930, No. 21618. [Class 40 (i).] In a totalizator the competitor's number is set up by depressing a key in each of tens and units bands, or in a field of keys arranged in decades, the registering circuit being eventually selected by co-ordination between two groups of lines connected with the keys. The lines may be multipled to the various ticket machines assigned in succession by a rotary switch. As shown in the Figure, a tens key TK and a units key UK may be depressed so that when the assigning switch AS completes circuit for magnets CKM, CKM1 contacts CK, CK1 are advanced to connect with the key contacts and thus complete circuit through the common line groups 10-19 and 21-29, 20 to the co-ordinate selector MR. This may be constructed as in Specification 280,654, [Class 40 (iv), Telephones &c.], so as to select one of a hundred contacts such as 41a and thereby extend a circuit to the register. The completion of the circuit to the selector energizes a relay R1 to complete a line at r11 through a selected stake value wire 40-44 and at r12, through a relay RB and win-place key WK, to make a further selection through line 31 or 32 and alternative contacts such as 41a, 41b to register the bet as for a win or place. The relay RB holds itself at rb1 and initiates the ticket-issuing operation by contact rb2, the holding circuit being broken at the end of this operation by the opening of contact mr. In a modification the seleotion of the registering circuits is effected by wiring each key to a separate relay and grouping the relay contacts so that a tens relay selects the group and the units relay determines the individual in that group. In a further arrangement, the grouping of the keys and their relays is by decades so that depression of a single key results in energization of a decade relay and of a units relay related as in the second arrangement.

Title: Method of removing carbon monoxide from carbon-monoxide-containing gases by catalytic reaction with steam
IPC: C10K3/04
Filed: 1960-10-20
Abstract: In the method of removing carbon monoxide from carbon-monoxide containing gases wherein the gases are subjected to a catalytic conversion reaction with steam to form carbon dioxide and hydrogen, deterioration of the catalyst by formation of carbon deposits thereon is prevented by first purifying the gas conventionally to remove tar, dust and other liquid or solid impurities and then, prior to conversion, passing the purified gas through an electrostatic precipitator the electrodes of which are so dimensioned or arranged that at least some parts such as 5 to 80% of the collecting electrode surfaces will remain free of deposits or will collect such deposits to an extent that direct contact between the gas and the electrode is not impeded.  The precipitator may comprise a number of high-tension fields arranged in series, with or without the interposition of a p desulphurization or benzene-removal plant, the first field removing substantially all the tar, dust and other impurities. The high tension fields may be operated at mean field intensities of 5-6,000 volts/cm. and the precipitator may operate at elevated temperatures of from 50 DEG C. to 150 DEG C.  The treatment of the gas prior to conversion may be controlled to ensure the introduction of major volumes of gaseous hydrocarbons into the reactor and to ensure that major volumes of water vapour remain in, or are taken up by, the gas in order to reduce the amount of steam required for conversion.  The initial gas purification may be effected electrostatically in a precipitator having electrodes large enough to provide the required second stage, with the discharge electrodes positively charged. Alternatively two serially connected precipitators may be used, the second precipitator operating on alternating current.  The spacing between the discharge and collecting electrodes in the precipitators may be from 2,5 to 12,5 cms.

Title: Improvements in or relating to the production of coloured artificial materials
IPC: C09B69/06
Filed: 1938-12-10
Abstract: 522,591. Lakes; colouring cellulose esters and ethers; artificial silk. BRITISH CELANESE, Ltd. Dec. 10, 1938, No. 36055. Convention date, Dec. 10, 1937. [Classes 2 (ii) 2 (iii) and 15 (ii)] Colour lakes are made by reacting a waterinsoluble anthraquinone dye, which has affinity for materials having a basis of an organic derivative of cellulose and which contains one or more amino or substituted amino groups of basic reaction, with tungstic, phosphoric or molybdic acid, or with a complex acid derived from two or more of these acids, e.g. phosphotungstic or phosphomolybdotungstic acid. Specified dyes are 1:4-di(methylamino)-anthraquinone, 1:4-di(methylamino)-5:8-diaminoanthraquinone, 1:5-dihydroxy-4-methylamino-8- aminoanthraquinone, 1-hydroxy-4-aminoanthraquinone, 1-amino-4-acetylaminoanthraquinone and 1-amino-2-methylaminoanthraquinone. In forming the lake the dye may be treated with the acid itself, or with a salt of the acid in the presence of an agent, e.g. hydrochloric acid, which liberates the acid from the salt. The lake may be incorporated in the spinning solutions from which the artificial materials are made, or it may be applied to the finished materials in a dispersion in a dye bath or in a printing paste. Alternatively, the lake may be formed on the material by first applying one component to the material and then treating the material with the other component or components. Examples describe the preparation of the tungstic and phosphotungstic lakes of 1:4-di(methylamino) -5:8-diaminoanthraquinone and their application to spinning solutions containing cellulose acetate and acetone, from which filaments are spun by extrusion into an evaporative atmosphere. Further examples describe the dyeing of cellulose acetate yarns or fabrics with the lakes dispersed with the aid of a.water-soluble hydroxy-ethyl ether of cellulose. In another example, the lake is pasted with a hydroxyethyl ether of cellulose, glycerine and gelatine, glue or other thickening are added, the paste is printed on a cellulose acetate fabric, steamed, and scoured in an aqueous soap bath. The Specification as open to inspection under Sect. 91 is not restricted to the three acids mentioned above but comprises the use of any acid which forms an insoluble compound with the dyestuff. It also comprises the use of other dyes having affinity for cellulose derivatives and containing one or more amino or substituted amino groups of basic reaction, such as azo dyes, e.g. p-nitrobenzene-azo-p-xylidine and p-aminobenzene-azo-naphthalene-azo-phenol, and nitrodiphenylamine dyes, e.g. 2-nitro-4<SP>1</SP>-acetylaminodiphenylamine. 1 - hydroxy - 4 - acetylamino - anthraquinone. is also specified. This subjectmatter does not appear in the Specification as accepted.

Abstract: 843,809. Direct call systems. BARON, O. Nov. 20, 1957, No. 36109/57. Class 40 (4). A source of audio frequency 55 is coupled by a capacitor 57 to the central battery 54 of an interconnecting system such that a calling subscriber is connected to the source to obliterate his reception until such time as the called party accepts his call. In Fig. 1, four stations are shown, each having switch hook contacts S1, S2; calling key contacts S6, S7; and keys 53, 54, 55 which when at rest, as shown, provide a path to a buzzer 24 from each other station and when operated connect audio tone from the common transformer 55 to the station. The leads from each key S3, S4, S5 at one station are connected to the reversed leads from a similar key at each of the other stations over a junction box 13. To call station 3, station 1 operates key S4 and takes down his hand set. As soon as switch hook contacts S2 operate station 1 has audio tone from transformer 55 over capacitor 57 connected in circuit with his receiver and the key 54 which is used to call station 1 from station 3. By operating calling key contacts S6, 57, tone from transformer 55 is connected over 56, the made upper contacts of S4, lamp 27 at station 1, the made contacts of the middle and lower contact sets of S4, line 11b, through the junction box 13 to line 11a of station 2 where the tone lights lamp 27 and energizes the buzzer 24. Should station 3 already be established in a call the buzzer 24 will be disconnected but the lamp 27 will still light and a path for audio tone over capacitor 57 to the caller will still be provided. Station 3 accepts the call by operating key S4 which breaks the paths for audio tone, either direct from transformer 55 or over capacitor 57 and by way of the calling stations receiver. In this condition lines 11a, 11b are connected in parallel at both stations so that conversation proceeds over both lines providing station 1 restores his calling key. The keys S3, S4, S5 may be self-latching and be released when the switch hooks are restored. Station 1 may also be furnished as a central loud-speaker station, as shown in Fig. 2, where additional lines go to transmit-receive trans-. ducers SP1, SP2, SP3, at the other stations and transducer SP4, and transistor amplifier T serves station 1. A talk-receive key S8 and station keys S9, S10, S11 are provided. Operation of a station key connects that wanted station's transmit-receive loud-speaker to the amplifier T, lights a local lamp and connects up the lamp and buzzer at the wanted station over line 118 and calling key contacts S6 of station 1, Fig. 1. The called station needs to take no action as the connection is wholly under the control of station 1.
