Inventor: SWALES WILLIAM HAROLD
IPC: D02G3/00
Filed: 1958-11-11
Abstract: 930,780. Spinning yarns; creels. JOHN LOCKWOOD & SONS Ltd. Nov. 24, 1959 [Nov. 11, 1958], No. 36123/58. Classes 120 (2) and 120 (3). Woollen yarns are spun on a mule or spinning frame supplied from packages e.g. condenser bobbins, of " roving " mounted on two or more rows of driven surface drums. The rovings are guided from the drums and combined in pairs or more by spinning, all the spindles being operated simultaneously, to produce folded yarns of uniform colour and/or quality or of two or more colours and/or quality, without subsequent twisting or doubling. As shown, the normal surface drum 1, mounting packages 2, is augmented by an additional drum 11, mounting packages 16. Single ends 6 and 17 from each drum are guided by raddles 3 and 15 and spun together in pairs on spindles 5.

Abstract: 1,055,967. Thermal regenerators. SIEMENSSCHUCKERTWERKE A.G. Jan. 17, 1964 [Sept. 13, 1963], No. 36239/63. Heading F4K. Heat is exchanged between cold and hot gaseous streams 4 and 11 by circulating separate quantities of particles across the streams and through return channels 14a, 14b and 14c. As illustrated heat exchange occurs in zones I and II bounded by gas permeable walls 1 formed by parallel steel or ceramic slats and gas impermeable walls 2. The particles in each circuit are passed to sets of inlet tubes 6a, 6b, 6c, each set comprising three tubes 6a, 6a 2 , 6a 3 , Fig. 3 (not shown), from which the particles fall in layers to an outlet device 12 comprising three groups of tubes, each group comprising three tubes connected in parallel and leading to a hopper. The flow of particles through the outlet device is controlled by a slide valve 13 working over all three outlets, Fig. 4 (not shown). The particles are raised from the outlets to the corresponding inlets by motor driven screws 15a, 15b, 15c. The part of the particle path III lying between the heat exchange zones is long compared with the length of the heat exchange zones and may be provided with baffles, Fig. 6 (not shown), to assist in maintaining separate layers of particles between the inlets and outlets. In a modification, Fig. 8 (not shown), the particle paths in the heat exchange zones are inclined to the gas flow paths.

Abstract: 776,529. Plate heat exchangers. AKTIEBOLAGET ROSENBLADS PATENTER. Dec. 20, 1955 [Nov. 29, 1955], No. 36409/55. Class 64(3) In a plate heat exchanger having adjacent spiral passages 1, 2 for the respective fluids in which the fluid in the passage 2 flows axially between headers 3, 4, at least one of the headers is partitioned by a ring-shaped wall 11 into concentric sections 3a, 3b. and the axially open passage 2 is closed in its spiral direction by a wall 13 at a position where the header partition wall 11 crosses said passage (see Fig. 1) the arrangement being such that the axially flowing fluid makes two or more passes through the apparatus. Figs. 1 and 2 show a two-pass arrangement for the axially flowing fluid which, on entering header section 3a flows through that part of the passage 2 communicating therewith to the return header 4 from which it flows through the remaining part of the passage 2 to header section 3b and hence to outlet 8. The header 4 may have an outlet 9 for condensate. The other fluid flows spirally through the passage 1 from an inlet 5 to an outlet 6. A modification in which the axially flowing fluid makes four passes in the passage 2 is described.

Filed: 1973-08-01
Abstract: 1412904 Semiconductor devices SONY CORP 1 Aug 1973 [25 April 1973] 36625/73 Heading H1K The mesh-shaped gate region 15 of a junctiongate f.e.t. is covered by a correspondingly shaped insulating layer 16 which surrounds discrete highly-doped source regions 17 in the holes of the mesh. The regions 17 are interconnected by a common source electrode 20 overlying the insulation 16. The p<SP>+</SP> gate region 15 is preferably formed by diffusion into a mesh-shaped recess etched through a silicon nitride, molybdenum or silicon nitride-on-oxide mask on the n- Si body 10, which ultimately forms the drain region and may have on its lower surface a diffused or epitaxial n<SP>+</SP> layer 13. The insulation 16 is then formed by localized oxidation through slightly enlarged apertures of the same mask (for the nitride-on-oxide mask the enlargement of the apertures may be effected only in the lower, oxide layer by wider-etching the upper, nitride layer). In the form shown an n<SP>+</SP> ring surrounds the insulation 16, but in two modifications this feature is lacking, being replaced in one case by an extension of the gate electrode 21 so as to overlap the outer periphery of the junction between the gate region 15 and the substrate 10 and in the other case by a peripheral capacitive field electrode connected to the source electrode 20.

A blunger has a rotary impeller with vanes 20 spaced from the shaft 15 and a stator in the bottom of the container 10 having vanes 24 surrounding the rotor; the vanes have annular end shrouds 22, 28, and the rotor and stator vanes are of opposite curvature with their inlet and outlet angles designed to coincide with the direction of flow of the material created by the vanes. The rotor vanes 20 are approximately tangential to the circle on which their inner ends lie and the stator vanes 24 oriented so that the materials are ejected radially; the depth of the rotor vanes at least decreases with increasing circumference to maintain constant the cross-section of the passages between them. Circulation of the materials up the walls of the container and down round the shaft may be assisted by a sloping false bottom 11a and by baffles 30.

A machine for processing leather or like sheet material, which is passed through the machine, comprises a processing tool and a device for automatically spreading out the material before it reaches the tool, which device comprises elements disposed on both sides of the centreline of the path of the material, which elements engage the material and each perform a circulatory movement, so that they draw the material away from said centre-line in opposite directions substantially perpendicular to said centre-line. The spreading device also comprises members for holding and guiding the centre of the material as it passes between the spreading elements. A machine, Figs.1 and 2, for paring sheet leather 4 comprises a conventional cylindrical paring knife 1, a pressure-applying roller 2 and a holding roller 3, and a plurality of parallel, rotating, spreading rollers, or endless, travelling belts 5 mounted on rollers 6, which engage one or both faces of the leather, on each side of its centreline, and thus draw the leather away from the centre-line in the aforementioned opposite directions. The belts may be toothed, and may be pressed against the leather by bars 11 urged by springs 12. The device for holding and guiding the central part of the leather comprises rollers 7 and 8. The roller 8 may be mounted in a yoke 9, and urged towards the roller 7 by a spring 10. Plates 13 and 14 may be provided, before the knife, to bend the leather and prevent leather parings from reaching the spreading mechanism.
