Patent GB-853884-A (GB)
Title: Improvements in or relating to telecommunication systems
IPC: H04B3/08
Filed: 1958-02-18
Abstract: 853,884. Unattended repeaters. GENERAL ELECTRIC CO. Ltd., and INGRAM, D. G. W. Feb. 6, 1959 [Feb. 18, 1958], No. 5204/58. Class 40 (4). The gain of a negative feed-back amplifier at a repeater station is monitored at a terminal station by having a signal characteristic of the repeater and injecting it into the amplifier in such a way that the transmitted amplitude of the characteristic signal increases as the gain of the amplifier falls and increases more rapidly than the gain falls. The invention may be applied to a frequency or time-division multiplex system using radio or cable links. A repeater may have an amplifier, as shown in Fig. 1, comprising three stages of grounded emitter transistors the multiplex path being over the terminals 30, 31 to 32, 33 and a local oscillator (not shown), producing a characteristic frequency of a given amplitude which when connected across terminals 50, 52 in the output circuit produces an output across the terminals 32, 33 of an amplitude comparable with that of the multiplex signals. The frequencies of the characteristic signals are chosen to lie below or above those used for the multiplex transmission. Reduction of gain produced by deterioration of components causes the amplitude of the characteristic frequency appearing at terminals 32, 33 to increase by virtue of the feed-back path which includes resistor 45 and capacitor 48. Separate amplifiers may be used in the go and return paths in which case the same characteristic frequency may be injected into both amplifiers at each repeater station and each terminal station receives gain monitoring signals relating to the incoming path only. If a common amplifier is used for both directions of transmission only one terminal station receives the signals. All characteristic signal frequencies may be filtered out of the transmission path at a terminal station and by mixing with the output of a variable oscillator each frequency in turn may be changed to a fixed frequency which is filtered, rectified, and used to indicate the gain of its amplifier.

Patent GB-595057-A (GB)
Title: Improvements in or relating to coated polymers and the formation thereof
IPC: C08F36/20
Filed: 1942-04-23
Abstract: Coated polymers are formed by applying to the surface of a base material formed by incomplete polymerization of an organic oxygen compound containing at least two polymerizable groups a coating of the same or similar material and then further polymerizing both the base and coating.  Suitable compounds are those described in Specifications 540,938, 574,606, 576,083 and 595,056.  In addition, there may be used esters of crotonic, propiolic and cinnamic acids with unsaturated alcohols, glycol or glycerol polycrotonates, glycerol di- or tri-allyl ethers, glycol dimethallyl ether, carbonic, carbamic, sulphuric and oxalic acid esters of allyl or methallyl "Cellosolve" (Registered Trade Mark), allyl and methallyl esters of phthalamide and adipamide, diallyl and dicrotyl ureas.  The polymerization may be conducted as described in Specification 595,058.  Alternatively, the gel may be formed in a mould of rubber, artificial rubber or the gel itself or monomer or syrupy polymer thickened by addition of polyvinyl acetate, polymethyl methacrylate or the solid monomer formed by treating allyl chloroformate with ethylene diamine may be extruded and polymerized on rolls or belts. The coating may be applied as monomer, syrupy polymer or a solution of a fusible polymer.  The coated gel may be shaped before further polymerization.  A glass or polished metal surface may be applied during polymerization and the coated polymer may be released from the mould one or more times to prevent fracturing.  In examples, diallyl phthalate, ethylene glycol bis-(methallyl carbonate), diethylene glycol bis-(methallyl carbonate) or ethylene glycol bis-(allyl carbonate) and benzoyl peroxide are heated until the viscosity had increased by 500 per cent and poured into a glass tray.  After heating to form a gel, the sides of the tray are removed and the sheet lifted.  The sheet is placed over a pool of similarly thickened monomer on a glass plate and rolled on to the plate from one edge so that no air is entrapped.  A second pool of monomer is poured on the exposed gel surface and a glass plate lowered over the coating to avoid air entrapment.  The sandwich is then heated first at 75 DEG C. and then at 100 DEG  C.  After removing the glass plates the sheet is further heated at 100 DEG  C.  Other examples describe coating a gel of diethylene glycol bis-(methallyl carbonate) with ethylene glycol bis-(allyl carbonate) or diallyl phthalate.  Specification 540,940 also is referred to.

Title: Improvements in the manufacture of powder metal compacts and diamond tools
IPC: B22F3/14
Filed: 1945-03-05
Abstract: 605,261. Making diamond tools; powder metallurgy. BOART PRODUCTS, SOUTH AFRICA (PROPRIETARY), Ltd. March 5, 1945, No. 5496. Convention date, April 6, 1944. [Classes 83 (ii) and 83 (iv)] [Also in Groups V and XXIII] A process of manufacturing a coherent body of metal powder comprises heating a moulded mass of the powder to sintering temperature, enclosing the hot body in a mould and compressing it while at sintering temperature. As applied to the manufacture of a diamondboring tool, diamonds 5, 6 are arranged in recesses formed in the upper surface of a plug 8 which closes the lower end of a light metal cylinder 7. The required amount of metal powder 14 is put into the cylinder which is then closed by a plunger 11 so shaped at its lower end as to facilitate its becoming firmly attached to the powder mass during sintering, to form the shank of the finished tool. This assembly is placed within a mould comprising a base plate 25 to which is hinged a comparatively heavy outer wall 15 with an internal taper 16 and a split sleeve 17 with a corresponding external taper closely surrounding the casing 7 and preventing distortion of the casing during the compression of the powder. A pressure of the order of twenty tons per square inch is applied to the cold powder by the action of the press ram 27 on the plunger 11. The casing assembly 7, 8 and 11 is then removed to a furnace and heated to sintering temperature, preferably 850‹C. to 950‹ C., after which it is given a further compression in the mould and then allowed to cool. In a modification, a core pin intended to form a part of a finished boring tool is assembled within the centre of the casing 7, the plug 8 and plunger 11 being in this case annular. For forming a diamond dressing tool, metal powder 14a and a diamond 35 are placed in a cylindrical recess formed in a shank 32x and are compressed within a mould by a plunger adapted to enter the end of the recess and then heated and repressed as before. The shank, the sintered metal powder and the diamond are then machined to the form shown in Fig. 9. Specification 614,544 is referred to.

Title: Motor vehicle steering system
IPC: B62D5/32
Filed: 1964-02-11
Abstract: 1,057,720. Steering vehicles. SCHEID MASCHINENFABRIK G.m.b.H. Feb. 11, 1964 [Feb. 12, 1963], No. 5750/64. Heading B7H. In a motor vehicle steering system with means for reducing the transmission of castoring forces to the steering wheel, the means is connected to the vehicle gear change mechanism whereby it is rendered inoperative in the upper speed range of the vehicle. In Fig. 1, movement of gear lever 1, which is connected to both gear-box 12 and steering gear 10, from low-speed zone I to a high-speed zone II, actuates a control element 13 to transmit steering reaction as by reducing the pressure in a pneumatic or hydraulic steering system or by disconnecting the steering shaft 14 from a non-reactive worm and nut steering mechanism and connecting it to a reversible worm and nut steering mechanism. In an alternative, Figs. 2, 3, a valve 28, which selectively provides feel, is included in a power steering valve 19 for controlling the connections between two double-acting hydraulic steering rams 41, 42 and line 21 from 8 lines 22, 23 to pump 46. The valve 19 comprises an opencentre valve spool 20 secured to the end of steering shaft 14 which is moved axially when rotated due to the reaction between the helical thread 18 of the shaft 14 and the internal thread of steering nut 15 which engages a sector 16 connected to the wheels through links 8, 9 to provide steering position feed-back. In the position shown of valve 28, no steering reaction is transmitted to the steering wheel but, when the valve is rotated through 90 degrees, pressure fluid enters chamber 34 through bores 30, 32 and/or 31, 33 applying axial forces to pistons 35, 36 which normally abut stops 37, 38. When the shaft 14 is rotated and hence moved axially, one of the pistons abuts on the corresponding flange 39 or 40 on spool 20, applying an axial force which produces a tangential force on the steering wheel due to the reaction between shaft 14 and nut 15. In a further alternative, a road roller (Fig. 5, not shown), the steering wheel is connected to the steering roller either through an hydraulic ram for site work or through a reversible mechanical steering mechanism for road travel.
