Title: Improvements in high frequency two way telephone systems
IPC: H04B3/20
Filed: 1925-02-10
Abstract: 248,900. Western Electric Co., Ltd., (Western Electric Co., Inc.). Feb. 10, 1925. Artifcial lines and balancing networks. - In a two-way wireless telephony system, the receiving channel is protected whilst transmission is taking place, and vice versa, by means which include a delay or retardation circuit comprising a large number of band-piss filter sections of the type built up of inductances in series and capacities in shunt. Fig. 5 illustrates an arrangement in which the number of individual units is reduced by utilizing reflection effects. If the switch S is open, current entering at 24 is reflected at S, and so traverses the network D<1> twice, thus enabling the number of sections to be reduced by half. If the switch S is closed, the current enters the amplifier repeater, part being absorbed, and part entering the hybrid coil 32, 33, half of this going to the balancing network N, and half returning through the network D1, as before. The amplifier A may therefore be used to compensate for attenuation..

Title: Stable preparations of alkali metal salts of estrone sulfate
IPC: C07J75/00
Filed: 1962-01-31
Abstract: The synthetic sodium and/or potassium salts of estrone sulphate are stabilized by admixture with at least one part by weight of N-methyl glucamine (A) to 10 parts by weight of the salt of estrone sulphate (B).  Preferably 1 part of (A) to 2 parts (B) are used.  The mixture, in association with a pharmaceutical carrier, may be administered orally e.g. in the form of tablets, powders, capsules and solutions; parenterally in the form of sterile solutions, and rectally in the form of suppositories.  The mixture may be prepared by mixing the solids or dissolving the solids in a solvent such as methanol and evaporating the solvent.

Abstract: 936,813. Making longitudinally seamed pipes; welding by fusion. M. R. FERRERUELA. Feb. 3, 1960 [June 5, 1959], No. 3779/60. Classes 83 (2) and 83 (4). A method of making longitudinally seamed pipes comprises curving a sheet to almost cylindrical form, passing the thus curved sheet through rollers, pulling the tube through a drawing die having, at its outlet end, a longitudinal opening coincident with the gap between the pipe edges, a welding electrode and conduit for the supply of flux material being provided at said opening. A pipe 3 of approximately cylindrical shape formed from a sheet curved in a die or press to bring its longitudinal edges adjacent one another, has two rods 14 welded to its end and joined by a cross-bar 13. A chain 12<SP>1 </SP>is hooked to the cross-bar 13 and to a carriage 12 pulled by a chain 10 driven by a motor 11 to pull the tube 3 through a series of pairs of rolls 4, one roll of each pair being formed with an annular ridge 5 co-operating with an annular groove 6 in the other roll, the rolls 4 serving to correct the curvature of the pipe. From the rolls 4 the pipe 3 is pulled through a drawing die 15 having a longitudinal opening 16 coincident with the longitudinal gap in the pipe, through which opening project a welding electrode 17 and a conduit 18 for the supply of flux material. An adjustable weld backing 19 is held inside the pipe and is cooled by hydraulic fluid from a conduit 24.

Title: Improvements relating to the manufacture of articles of ion-exchange resins
Inventor: KRESSMAN THEODORE ROGER ERNEST
IPC: C08J5/22
Filed: 1953-02-11
Abstract: Ion-exchange resins in the shape of sheets, rods, discs or tubes are made by copolymerizing a compound containing an ethylenic double bond and an acidic or basic group, e.g. acrylic, methacrylic and chloroacrylic acids and diethylaminoethyl methacrylate, with a cross-linking agent containing two or more ethylenic double bonds, e.g. divinyl benzene and ethylene dimethacrylate, the reaction mixture containing reactants and water in substantially the proportion required to make the product water-saturated, in general between 20 and 35 per cent of the reaction mixture, the whole reaction being carried out under conditions such that water cannot escape.  Copolymerization is assisted by catalysts, such as ammonium persulphate and diazoaminobenzene, and is preferably carried out in a closed vessel corresponding to the shape to be produced.  Sheets supported on filter paper, sintered glass discs or porous unglazed porcelain may be made by immersing the support in the reaction mixture before polymerization.

[Also in Group XIII] Relates to thermostatic control devices, for electric furnaces, of the kind having differential heat-expansion elements 9, 6 operating through motion-magnifying means 12 on a micro-switch 13 for the heating current. According to the invention, a tubular expansion element 9 has a closed end 12a operating the switch and an open end associated with a flap or like valve 17 which is automatically opened when the current is cut off, at a predetermined temperature, to permit flow of coolant e.g. air through the tube. In the form shown, the tube 9, made of heat-resistant alloy, and supported within a furnace 5 having a metal casing 6 and lagging 7, has the valve 17, at its lower fixed end and at its expansible upper end a plug 12a operating through lever 12 on switch 13. This switch is connected in circuit with an auto-contactor switch 8a 8b and with a solenoid 19b for actuating the valve 17. When the predetermined temperature is reached, the current is cut off and a spring 21 opens valve 17 to permit the flow of cooling atmospheric air through the tube 9 and passages 16. The temperature is set by an adjustable cam 14. In a modification Fig. 3 (not shown), a flap valve admitting air to a sheet-metal casing at the bottom of the tube 9 is actuated by linkage connected to the contactor switch arm 8b.

Title: Steam locomotive draught appliance
IPC: F23L17/16
Filed: 1962-02-05
Abstract: 930,628. Blast apparatus for locomotives. A. GIESL-GIESLINGEN. Feb. 5, 1962 [Feb. 13, 1961], No. 4329/62. Class 51 (1). A draught appliance for steam locomotives having a chimney of elongated cross-section and including a divergent diffuser portion and one or more exhaust nozzle openings is characterized by the fact that the angle formed between the longitudinal central plane of the chimney and straight lines drawn in transverse planes at 90 degrees to the aforesaid plane and connecting the edge of the exhaust nozzle opening with any point of the chimney, decreases with growing distance of the point of contact from the plane of the nozzle opening only until said distance reaches a minimum of 1“ times or a maximum of twice the distance between the narrowest section of the chimney and the plane of the nozzle opening and that the said angle increases again with further growing distance of the point of contact from the plane of the nozzle opening. The diffuser portion is formed as a conoidal body characterized in that the relation i/d-1 for the diffuser lies between 6 and 7 to increase the diffuser losses by a controlled amount. In accordance with the principals of the invention the relationship a/c-b lays between   6 and 6.5. These proportions have the effect of minimising the reduction in the air supply occurring whenever the flow resistance through the fire bed increases as any diminution of the flow will bring about a notable compensatory action due to diminishing frictional and diffuser losses. Specifications 683,234 and 793,073 are referred to.
