Title: Improvements in and relating to directly-heated cathodes for electric disharge devices
IPC: H01J1/15
Filed: 1938-11-23
Abstract: 506,150. Thermionic cathodes. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 23, 1938, No. 34063. Convention date, Nov. 23, 1937. [Class 39 (i)] A directly-heated cathode for electron discharge devices is formed by a plurality of individual conducting wires or ribbons which are either woven directly onto a core wire or woven together and then spirally wound onto a core wire. Suitable metals for the wires or ribbons are molybdenum, tungsten, nickel and copper, and different metals may be used for the individual wires or ribbons in order to combine mechanical strength with a low work function or to eliminate the stresses set up by the expansion on heating by choosing metals with suitable coefficients of thermal expansion. The woven construction gives a good hold for the oxide coating.

Title: Improvements relating to methods and apparatus for consolidating ground
Inventor: MENNELL ROGER PRICHARD NEWMAN
IPC: E02D3/12
Filed: 1958-10-27
Abstract: 858,319. Consolidating earth &c. SOIL MECHANICS Ltd. Oct. 21, 1959 [Oct. 27, 1958], No. 34346/58. Class 68(1). Water-bearing ground outside the lining of a tunnel is strengthened or made impermeable by injecting a treating-liquid through a hole in the lining, valve and sealing means being provided whereby the injecting means may be thrust into and withdrawn from the ground without an inward flow of water through the hole and without building up a super-atmospheric pressure within the tunnel. The lining 1 has a screwed opening 2 which receives a polyethylene ring 4 having a diaphragm 7 with radial lines of weakness. A similar diaphragm 11 on a screwed member 12 is spaced from the diaphragm 7 by sponge rubber 10. A screwed adapter 16 connects a piece of flexible rubber hose pipe 18 to the member 12, an externally operable iris-diaphragm valve 19 joining the hose 18 to another length 20 having a quick-release connection 21, similar to a fire hose connection, for retaining sealing means 23, 32 for the slidable injection pipe 33. The pipe 33 is thrust forward, through the opened valve 19, into and through the diaphragms 7, 11 and rubber 10, the diaphragms rupturing on their lines of weakness to allow the passage of the point 34 into the ground. After injection at one place, the pipe 33 is withdrawn until its point 34 is within the hose 18, the hose then being bent to allow the point to be reinserted in the ground at a different angle. This process is repeated at a number of different angles. When the pipe 33 is finally withdrawn, the diaphragms 7, 11 resume their original positions, effecting a partial seal against the inflow of water. The iris-diaphragm 19 is closed after the pipe 33 leaves it, thereby sealing the tubes 18, 20 and allowing the pipe 33 to be completely withdrawn and the sealing means 23, 32 to be withdrawn from the connection 21 by pulling out the latches 25. A rod 38, having a hexagonal socket end 42 to fit over a hexagonal spigot 41 on a stopper 39, is inserted through the sealing means 23, 32 which is again locked in the connection 21. The stopper 39 is advanced through the opened iris-diaphragm and is screwed into the internal threads on the member 12. The stopper has projections 43 on its leading edge to clear dirt from the internal threads. The injection apparatus is now disconnected by releasing the adapter 16. The valve 19 may be dispensed with if the tube is sufficiently flexible to be closed by external squeezing.

Patent GB-602434-A (GB)
Title: Process and apparatus for forming films and coatings
IPC: B29C48/91
Filed: 1945-12-19
Abstract: <PICT:0602434/IV(a)/1> An apparatus for making self-sustaining films is of the type in which an upwardly-moving film-receiving surface picks up a film of liquid as it engages with the lip of a weir over which the body of filmforming liquid flows and is characterised in that the weir is of flexible material whereby it forms a seal with the film-receiving surface and prevents seepage of liquid downwardly. The film-receiving surface comprises a rotating drum, endless band or long web from which the film is subsequently stripped.  The film-forming liquid L (Fig. 1) is contained in reservoir 2, the weir-wall 3 of which is of flexible material and bears against the surface A of the casting drum 1.  The liquid L is maintained above the top edge of the wall 3 by a constant-level device so that a layer of liquid is drawn upwardly by the drum surface.  The liquid layer is converted into a film by evaporation, cooling or oxidation <PICT:0602434/IV(a)/2> <PICT:0602434/IV(a)/3> <PICT:0602434/IV(a)/4> <PICT:0602434/IV(a)/5> <PICT:0602434/IV(a)/6> and the film is stripped from the drum by roll 4.  In a modification, an endless belt replaces the drum 1 and the layer of liquid is converted into a film by passing the belt through a solidification chamber.  The liquid reservoir may take the form shown in Figs. 4, 6, 7, 8, wherein the weir-wall 3, 3a, 3b and 3d respectively is of flexible material, the ends of the reservoir being closed by relatively movable dams 23 (Fig. 5).  The thickness of the film is governed by the viscosity of the film-forming liquid and the speed of the film-receiving surface. Effect materials such as metallic powders, pigments, dyestuffs and short fibres may be scattered on to the surface of the freshly-formed film.  Numerous types of flexible material suitable for the construction of the weir are given in the Specification, as also are numerous types of film-forming liquids.  The apparatus may also be employed for coating sheet materials with a film-forming substance (see Group VIII).

Title: Method of improving the structure of welding seams in workpieces welded in a machine by the electric flash-butt-welding method
IPC: C21D9/50
Filed: 1966-08-01
Abstract: 1,149,736. Welding by pressure. THEODOR WUPPERMANN G.m.b.H. 1 Aug., 1966 [19 Aug., 1965], No. 34471/66. Heading B3R. In order to improve the grain structure of a welded joint formed between workpieces in a flash butt welding machine an upsetting pressure is applied to the welded pieces while still in the machine, the magnitude of the pressure being such that flow takes place until the temperature of the weld drops to a level substantially equal to the transformation temperature of the metal of the workpiece, the temperature then being raised again to restart the flow of material at the weld. The temperature may be allowed to fall to the transformation point in this manner and raised again several times, the raising of the temperature being effected, e.g. by switching on the machine current. The cessation of flow at the weld may be indicated by means of a scale on which the distance between the jaws of the machine is indicated. The process may be repeated until a predetermined degree of total compression is obtained or till the workpieces have attained a desired finished size.

Title: Cable making planetary strander
IPC: H01B13/00
Filed: 1976-08-20
Abstract: In the case of a cable stranding machine for a cable which contains at least one optical fibre, in order that the latter is not subject to unacceptable tensile stresses and torsional loads, the coil carriage, a device for fitting a ribbon and the cable input device are each driven by a dedicated motor via a torque converter whose rotation speed can be regulated electrically, the electrical control signals for these three converters being adjustable independently but being electrically coupled to one another in order to maintain constant relationships between the rotation speeds of the three drives. The forks (27) for accommodating the supply coils (32) of the elements (33) which are to be stranded are supported in a plate (26) which is driven by a motor via a hollow shaft (20), an intermediate gear system (23) and an eddy-current torque converter (22). Each of the forks is provided with a gear wheel (28) over which gear wheels a chain runs which is driven by the hollow shaft (20). This prevents any torsional load on the drawn-off stranding elements (33) while the coupled drives, whose rotation speed is regulated, ensure a constant tensile stress, particularly during changes in rotation speed while the machine is being switched on and off, as well. <IMAGE>
