Title: Rotary piston internal combustion engine
Inventor: BAINS AKBAR SING
IPC: F02B75/02
Filed: 1968-06-24
Abstract: 1,263,917. Rotary-piston internal combustion engines. A. S. BAINS. May 27, 1969 [June 24, 1968], No.30007/68. Heading F1F. A rotary-piston I.C. engine comprises spaced apart closed annular chambers 10, 11, Fig. 1, in each of which is mounted a piston 13, Fig. 6, of circular cross-section connected to a common transmission shaft 16 for movement around the chamber. Each chamber includes an associated valve disc 17, 18 having a cut-out 25, 26, which is rotated in synchronism with the pistons through bevel gearing 23, 24 so that the pistons pass through the cut-outs. Gaseous fuel/air mixture sucked into the chamber 10 through a line 29 connected to a carburetter (not shown) is compressed between the valve disc 17 and piston 13 before being transferred through a valved passage 27, in which it is ignited, to the chamber 11. The expanding gases drive the piston 13 in this chamber and are finally exhausted through a line 30. A flywheel 15 is secured to the shaft 16 between the chambers. The pistons 13 are shaped at their leading and trailing ends 41, 42 to maintain a substantially constant clearance between the pistons and the cut-outs when passing therethrough. Each chamber includes a cylinder sleeve 31 and a casing 32 which may be either water or air-cooled. The shaft 16 and flywheel 15 include ducts 45, Fig. 5 through which lubricant can pass to nozzles on the piston to spray it on to the cylinder wall. It is then burnt with the fuel/air mixture in the manner of a conventional two-stroke. Alternatively, the lubricant may pass through a sliding valve 48, Fig. 9, which is synchronized to pass lubricant through an outlet 49 to between scraper rings 46b, 46a around the piston. In this case the oil is not burnt and returns to sump for re-circulation. The shaft 16 and flywheel 15 may also include ducts 55 through which air is transmitted to the interior of the pistons for the cooling thereof. Each piston 13 is connected to the flywheel 15 and hence the shaft 16 by means of an annular ring 34 which passes through a circumferential slot 33 in the piston and a connecting block 35. Sealing rings 39 are urged by gas pressure in the chambers to seal against shoulders formed on the ring 34 to seal the chamber against leakage. In another embodiment, cam discs rotatabe with the shaft 16 co-operate with valve discs which are reciprocated by linkage to divide the closed annular chambers and withdraw the discs to permit the passing of the pistons.

Title: Improvements in or relating to alternating current electric instruments for indicating synchronism, power factor, phase difference or the like
IPC: G01R25/00
Filed: 1921-11-11
Abstract: 188,532. Nalder Bros. & Thompson, Ltd., and Lipman, C. L. Nov. 11, 1921. Addition to 162,471. Phase-differences and power-factors, measuring. -- In alternating-current instruments described in the parent Specification in which two or more pairs of vanes forming separate coaxial magnetic systems are provided, the field coils, which may be joined in series, parallel, or seriesparallel, are all connected in one phase, so that only one current transformer is necessary. As shown in Fig. 1, two magnetic systems separated by non-magnetic material A are connected across the phases 1, 2, the field' coils F being connected in parallel in one phase. Instead of a pair of field coils for each vane, one pair of field coils common to both magnetic systems can be employed. For a three phase power-factor meter on balanced load, the magnetizing-coils may be con. nected in star or delta, with one field coil common to all three magnetic systems; or three field coils connected in series one for each pair of vanes. As a single-phase power-factor meter, Fig. 4, a phase-splitting device is employed, and this arrangement can be used as a single phase rotary synchroscope, the field coils being wound with fine wire. Potential transformers may be employed.

Abstract: 449,244. Fluorescent screens. RENWICK, F. F., 6, Reed Pond Walk, Gidea Park, Essex. Oct. 20, 1934, Nos. 30131/34,34590/34, and 1659/35. Drawings to Specification. [Class 98 (i)] An intensifying or viewing screen for X-ray use comprises a layer of a fluorescent zinc compound on a support having at or near its surface a layer containing a metal having an atomic number between 42 and 58 inclusive, the secondary radiations from which increase the fluorescence. The fluorescent material may be zinc sulphide or silicate, or zinc cadmium sulphide, and may be deposited in known manner by coating on a temporary support a suspension of the material in a binder such as collodion, and transferring the cast layer to its final support. This support may consist wholly of metal foil or sheet, or it may comprise a backing of metal (e.g. iron, copper, or zinc) or of a non-metallic substance (e.g. paper, card, or celluloid) to which is attached a metallic foil, or on which a metallic coating is deposited. The fluorescent layer may be applied directly on the metal foil or coating, or upon an intermediate non-metallic reflecting layer as of white paper. The metal, which may be chosen for its reflecting property, is preferably palladium, silver, cadmium, indium, tin, antimony or tellurium. Alloys of one or more metals of the class specified may be used, e.g. lead and tin; tin and cadmium ; cadmium, antimony and tin ; tin, antimony and lead ; or alloys of tin, cadmium and antimony with metals of lower atomic number, e.g. copper, nickel, zinc, or aluminium. The Provisional Specifications refer also to a fluorescent layer with a backing consisting of nickel or chromium or comprising a metal of higher atomic number than zinc.

Title: Improvements in and relating to the continuous casting of metals
IPC: B22D11/05
Filed: 1960-09-02
Abstract: 909,465. Continuous casting machines. CONCAST A.G. Sept. 2, 1960 [Oct. 5, 1959], No. 30306/60. Class 83 (1). In a continuous casting process the mould is horizontal or inclined thereto, and the mould and the casting are rotated in the same direction and at the same speed about their longitudinal axis, the speed being below that which would cause the formation of a tube by centrifugal action. The water-jacketed mould 14 is carried in a rotatable sleeve 17 journalled in bearings 18, 19. Supported on the sleeve 17 are spring-loaded extracting rollers 50 driven through gearing 55--62, 65, 66, 67, 69 from a common drive shaft 70 which drives the sleeve 17 through a spur wheel 26. The drive shaft also drives a cam 31 by means of which the mould is longitudinally reciprocated, within the sleeve, in the manner described in Specification 909,464, which is referred to. The shaft 70 also carries a magnetic clutch 84 which when energized by engagement of the end of the casting with a limit switch 81, drives rack-andpinion gearing causing a bell-crank lever 89 to move a saw 89 parallel to, and at the same speed as, the casting, while simultaneously a pneumatic cylinder causes the saw to tilt on its mounting 92 and cut the casting. The severed casting is ejected by arms 107 actuated by a pneumatic cylinder, the freeing of the limit switch 81 causing the saw to be spring returned to the initial position. The molten metal is fed to the mould by gas pressure from a tiltable container 1 carried by a carriage 3 movable by a cylinder 7. In a modification, Fig. 6, the driven extracting rollers 151 are not mounted on the rotating sleeve 17a, but are stationary and their axes are oppositely inclined to the axis of the mould so that they impose both rotary and feed motion to the casting. Further, the sleeve 17a may not be positively driven, but may derive its rotation from the rotation of the casting.
