Title: Improvements relating to metal compositions
IPC: H01H1/023
Filed: 1943-03-17
Abstract: 564,905. Composite metal. SIMS, F. R., and COMPOUND ELECTRO METALS, Ltd. March 17, 1943, No. 4360. [Class 82 (i)] [Also in Group XXII] Metal, of high electrical and thermal conductivity and of great hardness under conditions of prolonged high temperature and high mechanical pressure, is produced by permeating a porous mass of tungsten, molybdenum, silicon, boron or other hard heat-resistant metal with a metal such as silver or copper, this operation being carried out at a temperature below the melting point of the hard metal. The composite metal is employed in the manufacture of parts such as the arcing tips of contact assemblies of high-rupturing capacity switch-gear and die-facings for the electrodes of large flash-welding machines. In one method, short lengths of scrap tungsten rod are passed three times through a sledge mill and the product is sieved to isolate particles of from 1.168 to 2.362 mm. size which are placed loosely in a graphite mould which is then heated in a reducing atmosphere to 1300‹ C. or 1200‹ C. if copper or silver respectively is used as the permeating metal. After 15 minutes heating, strips of copper &c. are placed from time to time on top of the mould until a surplus remaining on the surface indicates that all the interstices have been filled, the resulting conglomerate being slowly cooled in an atmosphere of nitrogen. In another method, tungsten powder of less than 200 mesh is waxed pressed and sintered from 1250‹ to 1300‹ C. The product is crushed by pestle and mortar and particles as above are sifted out and treated as before. The resulting product may be crushed and again treated in a graphite mould as in the first method. In a further modification, the tungsten may be in the form of fine filaments. These may be pressed either along or with powdered tungsten formed in situ in the mass by reducing an oxide. Permeation of copper &c. thus takes place as before. An intimate mixture of copper and tungsten &c. may be formed prior to heating to melt the copper and in this case also the tungsten may be reduced in the mixture.

Patent GB-886644-A (GB)
Title: Process of purifying starch
Inventor: GAVER KENNETH MERLYN
IPC: C08B30/04
Filed: 1959-02-10
Abstract: Wheat starch is purified by adding an acid or acid-forming substance to said starch in a liquor suspension to lower the pH to within the range 3,0 to 4,0, steeping at this pH for between 2 and 8 hours within the range 90 DEG  to 115 DEG  F., separating impurities from said starch by centrifuging and/or screening, washing, adding alkali to the steep liquor to increase the pH to within the range 9,0 to 11,5, steeping at this pH for between 8 and 20 hours within the range 90 DEG  to 115 DEG  F., neutralizing, and filtering and drying.  In a modification of this process, the alkali steep is carried out first and the acid steep is carried out after the separation of impurities and before neutralizing.  The acidification may be effected with dilute sulphurous acid produced in situ by addition of SO2 to the starch liquor, preferably in an amount of 0,2% to 0,5% by weight. The alkali steep is preferably effected by addition of dilute caustic soda. The neutralization consists in adjusting the pH to within the range 5,0 and 7,2 by adding an acid, e.g. hydrochloric or phosphoric acid, or alkali, as appropriate.

Title: Method and apparatus for producing continuous lengths of shaped structures of synthetic organic thermoplastic material
IPC: D01D5/08
Filed: 1945-02-24
Abstract: Filaments or like structures of organic thermoplastic material in continuous lengths are produced by feeding the freely exposed end of a supply of the solid thermoplastic material into a short zone of radiant energy in which the thermoplastic is locally melted and, at the same time, exerting a pulling action at one or <PICT:0586425/IV/1> <PICT:0586425/IV/2> more points of the exposed end.  As shown in Fig. 1, solid thermoplastic material 10 is fed by means of driving rollers 12 into or near the focus F2 of an ellipsoidal reflector 17 which has, at its other focal point F1, an incandescent wire or lamp 16 which is heated electrically.  The filament 18 cast upon the winding drum 19 exerts the pulling action upon the exposed end of the material 29.  In a modification of this apparatus, a number of lamps are arranged in a plane at right angles to the exposed end 29 so that the radiant energy is focused at points of the material in that plane.  In another form of the apparatus the energy is focused at points of the material in such a way that the material is heated in stages.  In yet another form of the apparatus, the thermoplastic is preheated by means of a heating coil surrounding but apart from the thermoplastic material.  As shown in Fig. 5, the preshaped solid 40 is tubular.  A number of lamps are arranged in the plane AA at right angles to the tube so that the radiant energy is focused at points, such as 51 and 52, from each of which a filament 18 may be drawn.  A number of filaments may be similarly drawn from a rod supply of material.  The tubular material may be used as a means of introducing an inert gas atmosphere to the heated zone.  A tubular structure may be drawn from the closed end of a tubular supply and prevented from collapsing while plastic by the pressure of the inert gas.  The thermoplastic material may be polystyrene, a vinyl resin, polymethyl methacrylate, a polyamide, a cellulose derivative or a rubber-like plastic such as polyisobutene.  The radiant energy may be heat, light concentrated by a lens system or the electrical energy of a high-frequency electric field.

Title: Improvements in or relating to electrical monitoring circuits
Inventor: AVERY JOHN ARTHUR
IPC: H03K17/30
Filed: 1959-02-12
Abstract: 895,565. Protective arrangements. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Feb. 11, 1960 [Feb. 12, 1959], No. 4955/59. Class 38 (5). [Also in Group XL (c)] When the current I in a protected circuit goes above or below a predetermined range, it alters the bias on the base of a transistor TR1 to cause it to conduct or to cut-off and so produce the operation or release of a relay RA in the collector circuit of the transistor. In Fig. 2, resistor R6 is normally short-circuited by a transistor TR2 and the current I flowing to earth through a bias resistor R1 produces a potential drop across the resistor R1 in opposition to the potential due to the battery ES with the result that the transistor TR1 is cut-off and the relay is not energized. In the event of the current I falling below the lower limit of the predetermined range, the potential drop across the resistor R1 due to the current I is reduced and the base becomes sufficiently negative for the transistor to conduct. Should the current I exceed the upper limit, then the potential produced by the current across a resistor R4 is sufficient to cause the transistor TR2 to cease conducting and so remove the short-circuit from resistor R6. The base-emitter voltage of transistor TR1 then becomes negative so that transistor TR1 conducts and the relay RA is energized. Fig. 3 (not shown) illustrates a modified arrangement in which the transistor TR1 is normally conducting.

Title: Improvements in or relating to the manufacture of gramophone recording blanks
Inventor: RAND WALTER LESLIE
IPC: B29D17/00
Filed: 1954-02-23
Abstract: <PICT:0774526/III/1> <PICT:0774526/III/2> A method of manufacturing gramophone recording blanks comprise feeding uncoated cores to a coating device and thereafter transferring the coated cores to a drying device with the adjacent cores supported in planes spaced from one another, Uncoated cores 15 are conveyed on a band 1 to a lacquering device 13, the band being unwound from a reel 2 and rewound on a reel 3 after passing over a plate 5 and between driving rollers 7, 8. The roller 8 is driven by an electric motor 10 which also drives the reel 3.  Excess coating is removed from the bond by a scraper 16 and is collected in a shoot 17.  The cores pass to transfer cams 18 intermittently driven which feed the cores over supports 31, 311 of different thickness which are fed along a channel 36 from a band 33 in a channel 32 to beneath the core by electro-magnetic devices 35 as described in Specification 645,053. The cam transfer mechanism 18 and the feed of supports 35 are synchronized by a photo-electric cell 37 and relay 40.  The supports ascend a ramp 25 on a conveyer band 22 where they contact the cores and then pass on the band over a plate 25, which leads to a coating device having an endless belt 27 for supporting the band 22, the belt being driven from the motor 10.  The bands 1 and 22 may be driven at the same speed or the band 22 may be driven more slowly so that the coated cores overlap.  To assist the ascent of the cores up the ramp 25 the supports may be made of magnetic material and a magnet placed below the ramp.  The other side of the core may be similarly coated to produce double sided records.

Title: Improvements in or relating to installations for making short-exposure radiographs
IPC: H05G1/60
Filed: 1934-02-17
Abstract: 420,637. R÷ntgen - ray apparatus. MULLER AKT.-GES., C. H. F., 24, R÷ntgenstrasse, Hamburg, Germany. Feb. 17, 1934, No. 5301. Convention date, Feb. 22, 1933. [Class 39 (i)] The passage of a current impulse through an X-ray tube 1 for making a short-exposure radiograph is caused by temporarily shortcircuiting a resistance 9 connected between the control electrode 7 and the cathode 8 of a 3-electrode tube 6 in series with the tube 1 in the high-voltage circuit. The negative bias on the electrode 7 due to the resistance 9 is removed when the resistance is short-circuited and may be replaced by a positive bias due to a battery 10 or to an aggregate comprising a condenser and a valve supplied with alternating current, the power consumed by the tube 6 during the exposure being thus reduced. The resistance 9 may be short-circuited by a gravity-influenced pendulum 11 or control hammer. Operation of a switch 15 causes in succession the energization of a coil 12 to hold the pendulum 11 at one side, energization of the heating circuits for the cathodes in the tubes 1 and 6 and of the high-tension transformer 4, and de-energization of the coil 12, so that the pendulum swings across and is locked at the other side by energizing the coil 13. For successive exposures in X-ray cinematography, brushes connected to the ends of the resistance 9 are shorted by a contact on a drum rotated by the film-driving device. To vary the short-circuit period, the drum may have contacts of different angular extent each brought into operation by moving the drum axially. Specification 294 408, [Class 98 (i)], is referred to.
