Patent GB-230070-A (GB)
Abstract: 230,070. Bornand, E. March 1, 1924, [Convention date]. Sealing-wax. - Light crystals of solid polymerized aldehydes, such as metaldehyde or trioxymethylene, are formed into small sticks of small transverse section, e.g. cores for sealing- wax, by forcing the material into thin slabs and sawing such slabs into sticks of the desired section. The cutting may be effected by a series of circular, reciprocating, or band saws, relatively adjustable, co-operating with a movable casing or holder slotted for the passage of the saws. Several slabs are superposed and, to avoid breakage, the saws are moved at a greater speed than the casing. The severed sticks may be divided into definite lengths.

[Also in Group XXVI] A method of making a turbine or compressor blade, Fig. 9, having one or more passages 10, 11 for a cooling or heating fluid comprises forming inner and outer hollow tubular elements 6, 1, assembling them together to provide at least one space 10 therebetween and then deforming them simultaneously by pressure applied to the wall of the outer element to lock the inner element firmly in position. The outer element 1 is made by forging; its walls may be of varying or constant thickness and its bore may be conical or cylindrical. The inner element 6 may be made by forging or may be cut from a piece of tube and one end closed; the outer surface thereof may have longitudinal grooves 8, Fig. 5, and its wall thickness may vary both along its length and also to provide opposite thin portions 16; alternatively the wall thickness may be constant, Fig. 4 (not shown). The inner element may have a constant or tapering outer diameter. After insertion within the outer element, the inner element is located by a clamp or jig and both elements are then pressed in a series of steps to aerofoil shape with the thin portion 16 of the inner element being located adjacent the leading and trailing edges of the blade. The grooves 8 may be filled during pressing with a cement which is subsequently removed to leave passages 11. The two elements may be secured together by brazing. Finally the root is machined to fir-tree shape, Fig. 7, a fluid inlet passage 13 is drilled through the root and passages 14 are formed in the trailing edge communicating with the passage 10. Other passages may be formed in the outer wall to communicate with the passages 11.

Title: Improvements in and relating to semi-conductor lamps
Inventor: WILSON GEOFFREY WILFRED
IPC: H01L33/00
Filed: 1964-06-04
Abstract: Semi-conductor radiation sources are provided in which light is emitted from semi-conductor which might not readily be made into PN junction diodes.  A base made of a semi-conductor such as germanium or silicon is coated with a layer of the frequency determining semi-conductor.  An array of parallel strips or a lattice grid of a semi-conductor of opposite conductivity type to the material of the base is deposited on the layer by evaporation or sputtering.  This last semi-conductor may be the same as that of the base.  A source of direct current is connected in the forward direction between electrodes on the grid strips (which are connected in parallel) and an electrode on the base.  Light is emitted from the spaces between the grid strips.  Suitable materials for the layer are zinc selenide and zinc telluride (visible light), zinc sulphide (U.V.), and gallium arsenide, gallium antimonide, cadmium sulphide, indium phosphide, indium arsenide, indium antimonide, aluminium arsenide and tellurium (I.R.).  It is possible to provide a layer of the frequency-determining semi-conductor on each side of the base, a semi-conductor grid being formed on each layer.

Abstract: 627,851. Sifting apparatus; pneumatic separating. DEHN, S. G. (Haaky Manufacturing Co.). Aug. 6, 1946, No. 23306. [Class 117] [Also in Group XXX] A scalper for grain and the like including a pair of cylindrical scalper screens rotating about parallel axes in opposite directions, has a grain support between the screens arranged to permit the movement of impurities from the support over the tops of the screens, while granular particles of proper size are permitted to drop through perforations of the screens. In the construction shown, cylindrical screens 41 and 43 are simultaneously rotated in opposite directions about shafts 30 and 31 respectively by gearing from a pulley 39. The upper portions of the screens are sealed from a grain exit 20 by baffles 46 and 47 having flexible seals 49 and by a plat-' form 50 with flexible seals 52. Within the upper chamber so formed, the incoming grain is confined between the ends of the drums by baffles, one of which, 54, is shown extending from the top 27. Two pairs of semi-circular clamping plates 57, 59 are secured to each baffle, each pair of clamping plates embracing a flange 56 at one end of each drum. Felt sealing pads may be secured to the inner faces of the clamping rings 57, 59. In operation; grain enters an inlet 62 (see Group XXX) and falls in a thin film between baffles 75 and 76, controlled by a weight 82. Air is sucked in through an aperture 65 by a fan 70, passes through the " curtain " of grain, and then to the fan intake 69 together with dust &c. from the grain. The grain falls on to the platform 50 and is directed by a divider 51 against the upwardly moving surfaces of the screens 41 and 43. The larger impurities are carried by the screens along their upper surfaces, and are dropped into "talings" chutes 21 and 22. The grain and small heavy particles drop through the screens into the interior, and may pass out through the lower parts of the screens, or between spiders 40, 42, into an aperture 20 leading to the next stage of cleaning or separating.

Abstract: 289,323. Kewley, F. E., Buckley, H. S., and Buckley, C. A. M. Sept. 6, 1927. Arc lamps.-The electrodes of an arc lamp are separated gradually against the action of a dashpot by means of an unbalanced lever, which is liberated when the current is switched on by the action of a solenoid. The upper electrode 4 slides in a tube 7 and is provided with a collar 13 secured to it carrying a terminal 14 and a collar 12 sliding on it and carrying a clutch-lever 17 adapted to grip the electrode. The lever 17 is connected by a link 23 to a lever 26 weighted so that the end carrying the link 23 tends to rise, causing the lever 17 to grip the electrode and raising the electrode. To the lever 26 is pivoted the pistonrod 30 of a dash-pot 32. Through a hole in the lever 26 passes a rod 34 having a stud 35 at its end and connected by a chain 36 passing over a pulley 37 to the core 40 of a solenoid 44. The pulley 37 can be adjusted by means of a screw 42 and rod 41 supporting a lever 38 which carries the pulley. When the current is switched on the core 40 is raised, allowing the lever 26 to fall and raise the electrode 4. On the current ceasing the core 40 falls, raising the weighted end of the lever 26 and causing the lever 17 to strike against an adjustable collar 20, thus releasing the electrode 4. Fig. 4 shows an arrangement for two arcs in series, the upper electrodes 4, 5 being operated by the same lever 26.

Abstract: 520,076. Colour photography. KODAK, Ltd., and JELLEY, E. E. Aug. 12, 1938, No. 23833. [Class 98 (ii)] In a process for the production of coloured images in multi-layer colour photographic material wherein light sensitive silver salt images in the layers have to be selectively exposed, the light sensitive salt in an outer layer or in both outer layers is exposed with the aid of ultraviolet light having a wavelength wholly within the range which the emulsion binder, e.g., gelatine is capable of absorbing. The ultra-violet light may be obtained by filtering light from a line or continuous source through a filter, which may consist of an ultra-violet transmitting solid distributed in an ultra-violet transmitting medium, the dispersions of solid and liquid being different but their refractive indices for the selected wavelength may be the same, and, whose temperature may be controlled. The method may replace the exposure to red light of the lower layer described in example 1 of Specification 500,826, and the exposure to coloured light of the lower layer of a three-layer element, after removal of the negative silver, as described in Specification 501,000, or may be applied to the process of Specifications 501,002, Specifications 440,032 and 500,717 also are referred to.
