Title: Asymmetrical filter for removal of suspended material
IPC: B01D46/52
Filed: 1977-04-20
Abstract: The asymmetric filter for suspended matter is suspended in a frame (1) and is composed of a strip- or belt-like filter material (2) folded in a concertina manner; between each layer of the filter material (2) is arranged a folded or pleated film (3; 3') made of aluminium, card or plastic, in order to maintain the required spacing between the layers. This film, on the dust inlet side of the filter for suspended material, has a larger fold (3), in order to achieve a wider spacing between the layers of the filter material (2) than the film which is arranged on the clean gas side of the filter material. <IMAGE>
Patent GB-1048493-A (GB)
Title: Apparatus for steplessly varying the magnitude of the stepped changes in a variable gearing
IPC: D01H1/36
Filed: 1965-04-15
Abstract: To permit a stepless variation in the size of the steps in which the transmission ratio of the belt-and-cone gearing of a roving frame is changed during a wind, the angular position relative to its own axis of a planet 9 Fig. 1 (not shown), inside a sun 12 can be adjusted at will; if it is desired also to vary the ratio during a wind, its angular position is additionally changed as the wind proceeds.  The gear 9 is connected to a rocker-arm 7 through a pivoted link 8; as the arm 7 is rocked it inclines forward a control shaft through a one-way clutch 6 to rotate step-wise a worm 5 engaging a nut connected to the belt 3. The arm 7 is caused to rock by moving the axis of the planet 9 through a right angle with each stroke of the traverse, the planet being then rotated by engaging the internal teeth of the sun; to this end, a piston 14, which reverses with each stroke of the traverse in a cylinder 13 controlled by an electromagnetic valve-slide, actuates, through a rack and pinion, a shaft 11 carrying a rocker arm 10 fastened to the axis of the planet. By presetting the angular position of the planet about its axis, the angular stroke of the rocker 7 is changed according to the change in position of the point where the link 8 is attached to the planet. The axis on which the arm 10 rocks coincides with the rotational axes of the sun 12; the diameter of the planet is half that of the sun and the latter has twice the number of teeth than the planet, so that the point at which the link is attached to the planet, moves in a straight line as the planet moves.  To set the position of the planet, the sun 12 is rotated by a gear 19 engaging its external teeth when a knob 22 is loosened; the extent of the rotation is indicated by a pointer 20 which co-operates with a scale on a disc 21.  To vary the angular position of the planet 9 as the wind proceeds, the sun 12 is gradually inclined round by tightening the nut 22 so that disc 21 can drive the gear 19; the disc 21 is pivotally secured to an arm 23 with two rollers at its lower end, one, 24 of which is constrained by a guide 26 to travel in a vertical path and cause the other, 25, to bear radially on a cam groove 25 in an interchangeable plate 28 driven by worm-gearing from the control shaft.  The groove may be replaced by a cam surface on the upper face of a driven plate.

Abstract: 697,615. Welding chain links by pressure. DUNN, J., and ROBERTS, D. Nov. 26, 1951 [Sept. 1, 1950; Sept. 18, 1950], Nos. 16480/50 and 22831/50. Class 83 (iv). [Also in Group XI] In pressure welding the ends of an unclosed chain link, electromagnetic induction heating is applied at least to the said ends. In an embodiment unclosed wrought iron links 11 are linked with preformed links 10 in a machine fed with stock and preformed links and the linked chain is fed step-by-step on rollers past a heating device 14, Fig. 1, and a welding device 15. The chain could be formed entirely of unclosed links. The heating device 14 is formed by two conductors 16, 17 fed with highfrequency current and having grooves faces 18, 19 such that when the members 16, 17 are moved mechanically towards the oblique link ends 12, 13, they embrace them but are insulated therefrom and from each other. The instantaneous current flow is indicated by arrows. The members 16, 17 are mechanically moved apart automatically when the ends 12, 13 are white hot and the chain is fed to the device 15 which comprises a pair of primary dies 20, 21 whose faces 22, 23, Fig. 3, are moved together by mechanism synchronized with the moving means for members 16, 17 upon the ends 12, 13 to effect welding and a pair of secondary dies 24, 25 which are moved transversely by engagement of inclined faces 28, 29. On removal of dies 20, 21 a spring 30 retracts the dies 24, 25. In a modification for use with thicker chains the heating means comprises two conducting parts similar to 16, 17 but which embrace also the limb remote from the unclosed ends. Reduced heating on the said limb is provided. A separate means fed with a lower current may be employed for the said limb. The chain may be fed continuously when the heating and welding devices are moved with the chain whilst acting and then returned or they may be stationary in which case the welding means comprises a roller for welding. A plurality of heating and welding devices may be used. Welding, pressure may be applied whilst heating is being applied or while the heating means is in position but with current reduced or off. The oblique ends of the link may, alternatively, be stepped, and the limb section may be oval or rectangular. Specification 689,391 is referred to in the second Provisional Specification.

Abstract: 600,281. Fused silica. QUARTZ & SILICE. June 29, 1945, No. 16616. Convention date, June 30, 1944. [Class 56] Transparent silica glass analysing 99.99 per cent SiO 2  and opaque silica glass analysing 99.9 per cent SiO 2  (the impurities in the latter case being intentionally added) are obtained by melting purified silica using a pure graphite crucible or electrode, the standards of purity being, for the silica, either that the magnetic susceptibility of a powder thereof is approximately - .404 x 10<SP>-6</SP>, or that a sample is free from cristobalite after heating to 1630‹ C. for 2 hours, and for the graphite, that it analyses at least 99.99 per cent pure carbon. The silica may be obtained from rock crystal, siliceous sands (e.g. Fontainebleu) or pure quartzite (large pieces being first heated, quenched and ground in an iron mill), and purification processes are described involving treatment with hydrochloric acid, heating to 1000‹ C. to convert iron sulphide and carbonate into magnetic oxide for magnetic separation, and washing in water purified, e.g. by passage over zeolites. The graphite may be prepared by heating to at least 3000‹ K. by passage of an electric current therethrough in the presence of an inert gas, a temperature gradient between the interior and the surface of the graphite being produced by energy losses, whereby the impurities are distilled off and eliminated by convection or circulation of the inert gas. The crucible may be lined with coarse grains or small pieces prepared as above and kept in place prior to fusion by a sheet of ash-free paper. Optical glass may be obtained by heating a charge of the purified silica for an hour at a temperature below 1610‹ C. After sandblasting, the ingot may be cut up, submitted to an oxidizing remelt, and subsequently reheated to remove stresses. For an opaque glass, fine and coarse grains are removed from the raw material by sifting prior to washing, and water, steam or an aqueous solution or oxide suspension (e.g. a suspension of alumina or clay) is added in controlled quantities to the charge directly, or by damping the electrode therewith.

Title: Improvements in radio receiving apparatus
IPC: H03D1/16
Filed: 1929-05-31
Abstract: 312,698. Kramolin, L. L. de. May 31, 1928, [Convention date]. Thermionic heterodyne receivers. -In a superheterodyne receiver, the incoming and the local oscillations are applied to separate grids in a multi-grid valve. The receiver is designed to receive on two wave bands and the intermediate frequency is chosen to lie between the two bands. The aerial is connected by a switch 7 to either of two bandfilters arranged to respond to the two bands of waves to be received. The aerial oscillations are applied to one grid of the multi-grid valve 1. The local oscillations are generated in a tuned circuit 6 connected to one or more further grids in the valve 1, and back-coupled to the plate circuit. The oscillations serve substantially to paralyse the valve 1 during one half-cycle, and to allow it to operate as an amplifier during the other half-cycle. This manner of operation is stated to diminish interference by undesired frequencies. The circuit 6 has a tapping connected to the switch 7 so that the local frequency band is selected simultaneously with the incoming frequency band. Tuning is effected by a single control connected to the variable condenser of the circuit 6. The intermediate frequency amplifier comprises valves 2, 3, 4 with tuned inter-valve circuits, and stable working is ensured by using screen-grid valves in stages 2 and 4, and a frequency-doubling valve in stage 3. Push button or like selection of desired stations may be provided for by switching in selected condensers across the coil of the tuned circuit. A screw adjustment of the condensers may be provided for final accurate tuning. Specifications 301,498 and 311,295 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the local oscillations may be produced by one of the valves 2 - - 5, or that an independent valve may be used. This subject-matter does not appear in the Specification as accepted.
