Patent GB-492514-A (GB)
Title: Automatic telephone systems
IPC: H04Q3/42
Filed: 1938-05-05
Abstract: 492,514. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. May 5, 1938, No. 13458. Convention date, May 6, 1937. [Class 40 (iv)] Instead of dialling, the calling subscriber pronounces the designation of the wanted subscriber into the microphone, and the resulting complex currents are analysed at the exchange into component fundamental frequencies and are translated into numerical form for controlling the selectors. The invention makes use of the fact that different words may be distinguished by their sound-frequency spectra. The spoken designation may comprise the code letters of the exchange as well as the number of the wanted subscriber. The calling line is extended to a finder-selector link 101, 103, with which the recording and translating apparatus is associated by a switch 105. The complex currents pass through an amplifier 109 in parallel to a number of band-pass filters 100-130 which are tuned to particular fundamental frequencies and which control selflocking relays 106-108 through gas-discharge tubes such as 112, 113. An A.C. source 111 is inductively coupled to the tubes 112, 113 to extinguish them shortly after they are fired. An additional band-pass filter 140 responsive to all speech frequencies, feeds gas-discharge tubes 142, 143 which are included in the locking circuits of relays 106-108 and which are extinguished by an inductively coupled A.C. source 141 when an interval occurs between the words of the spoken designation. The contacts of relays 106-108 are wired to control digit relays 160-169, one of which operates in response to each word representing a letter or digit. The digit relays 160-169 control relay registers which bring about the setting up of the connection in the usual manner or in a small system the digit relays may control the selectors directly.

Friction clutches.- Friction bodies for brakes, clutches, &c. are formed by winding or stretching threads, cords or wires on suitably shaped formers, so that the threads &c. are disposed in the direction in which the frictional stress is to be applied. The threads may consist of asbestos or cotton fabric or wire netting, impregnated before or after the winding operation with a suitable hardening material, the wound body being hardened by the application of heat and pressure. The method of winding a disc shaped friction body is shown in Fig. 2. The former 2 is provided with flanges 3, 5 and the cord 1 is wound thereon in superposed layers, a number of radially disposed threads or wires being preferably wound round the cord, these being arranged either singly, as shown in the upper part of the Figure, or in pairs, as shown in the lower part thereof. The body may be strengthened by drawing a number of threads or wires 6 through it after winding, or radially disposed needles or flexible wires may be incorporated in the body during winding. A number of cords 1 may be wound side by side to form a heavy friction disc. Any desired shape of former may be used, and the threads or wires may be stretched over its surface instead of being wound thereon.

Abstract: 200,068. Thewes, W. O. July 1, 1922, [Convention date]. Pivoted and sliding jaw wrenches; jaw faces; handles and shanks.-An adjustable wrench, of the type comprising a fixed jaw 15 carried by a handle 2 formed in one with a casing 4 adapted to receive the shank 12 of a sliding jaw 5, is provided with an adjusting nut 14 freely mounted on the shank 12, a spiral spring 8, which normally tilts the jaw 5 forwards, being interposed between a wall of the casing and the shank. The spring 8, which is enclosed in a recess 21, engages the shank 12 through the intermediary of a shoe 23 provided with bent up prongs 25 disposed within the spring. The shank 12 rocks about a fulcrum 31 on the wall 32 of the casing, the line of pressure of the spring being below this point. The nut 14 bears against a cam surface 18 on the end 17 of the casing 4, the arrangement providing a final grip. The part 17 has lateral extensions which increase the bearing surface for the nut and protect it against undesired rotation when the wrench is laid down.. The nut 4 is retained on the shank 12 by bending up the last thread 19 or by means of a U-shaped device engaging in the channel of the screw thread. The handle is tapered both as regards width and thickness. In a modified form the spring 8 is mounted in a recess in the wall 32, the fulcrum 31 is on the inner wall and the line of pressure is above the fulcrum. Specification 198,369 is referred to.

Title: Production of monocyclic aromatic tri-isocyanates
IPC: C07C263/10
Filed: 1947-05-23
Abstract: Benzene 1 : 3 : 5 - tricarbonimides (triisocyanates) which may be substituted in the 2-position by an alkyl, alkoxy or aryloxy group are applied to cellulose which is then heat treated. Chemical reaction occurs which modifies the surface properties of the cellulosic material.  Specified substituents in the 2-position are methyl-, ethyl-, methoxy and phenoxy.ALSO:Monocyclic aromatic tricarbonimides (isocyanates) are prepared by passing phosgene into a suspension of a trihydrochloride of a compound of the formula <FORM:0631025/IV (b)/1> where R is hydrogen, an alkyl group or an alkoxy or aryloxy group, in an organic volatile diluent inert to the reactants and to the characteristic radicals of the reaction products, at a temperature not less than about 90 DEG  C., preferably at 90-130 DEG  C., while removing the hydrogen chloride liberated. The reaction should be performed in the absence of moisture.  The products may be separated and purified by distillation, which is facilitated by using a solvent having a boiling point not exceeding 160 DEG  C. Suitable solvents are hydrocarbons, halogenated hydrocarbons or ethers, e.g. toluene, xylene, ligroin, tetrachloroethane orthochlorotoluene, anisole, dioxane, monochlorobenzene or mixtures of these with, e.g. ethylene dichloride or benzene. Hydrochlorides of amino-aryl chloro carboxyamides and aryl trichlorocarbamides are formed as intermediate products.  The products react with alcohols for form urethanes with water to give amines and with ammonia or amines to give aryl ureas or aryl alkyl ureas.  They may be used to modify the surface properties of cellulose textiles.  In examples there is described the treatment with phosgene of monochlorobenzene solutions of (1) 1 : 3 : 5-triaminobenzene trihydrochloride; (2) 2 : 4 : 6-triaminotoluene trihydrochloride; (3) 2 : 4 : 6-triaminoethylbenzene trihydrochloride; (4) 2 : 4 : 6-triaminoanisole trihydrochloride, and (5) 2 : 4 : 6-triamino - 1 - phenoxybenzene trihydrochloride giving in each case the corresponding tricarbonimide.  Aromatic triurethanes.-Treatment of the tricarbonimides produced according to examples 1-4 with absolute alcohol gives the corresponding triurethanes.  Aromatic tricarbamides.-Treatment of the tricarbonimides produced according to the examples with dry ammonia or amines in ether gives the corresponding tricarbamides.  2 : 4 : 6 - Triamino-anisole hydrochloride is produced by catalytic reduction of trinitro anisole with hydrogen in the presence of Raney nickel. Specification 625,350 is referred to.
