Title: Improvements in and relating to compressed air starters for engines
IPC: F02N7/06
Filed: 1929-11-21
Abstract: 343,916. Turning-gear. HARCOURT, J. M. H. B. D', 108 bis, Rue Carnot, Suresnes, Seine, France. Nov. 21, 1929, No. 35709. Convention date, July 16. [Class 7 (v).] In a compressed-air starter, the starter pinion 21 is moved axially into engagement with an engine gear 39 by the action of fluid pressure on a piston 35 sliding in the hollow shaft 31 of the compressedair motor, and the compressed air is admitted simultaneously to the inlet port of the compressedair motor and to the hollow shaft 31, so that the pinion is set in rotation simultaneously with its axial movement. The pinion 21 is carried by a plain sleeve 38 sliding on the shaft 31 and connected to the piston 35 by a pin 36 passing through slots in the shaft 31. A tension spring 41 within the shaft 31 normally holds the piston and pinion in the position shown. On admitting compressed air to the inlet 5 of the compressed-air motor, the air is also admitted through ports 44, 46 and a chamber 45 to the interior of the shaft 31 and acts on the piston 35. The chamber 45 is made air-tight by cup leathers 47, 48. The compressed-air motor is described in Specification 342,404, [Group XXVI].

Abstract: 821,717. Making television tube frames; deforming hoops; stamping; flanging. CORNING GLASS WORKS. Nov. 26, 1956 [Dec. 2, 1955], No. 36110/56. Classes 83 (2) and 83 (4). [Also in Group XL (a)] A method of forming a metal frame for use as a sealing element between glass television tube envelope parts comprises deforming a circular metal hoop into generally rectangular form and then forming it with an inwardly-directed flange. A metal strip is bent into a hoop 12 with the ends abutting, which ends are then welded together and excess weld metal removed. A strip is similarly formed into a hoop 22 and fitted tightly inside the hoop 12 and welded or otherwise secured thereto. The compound hoop is then placed in the lower part of 51, 52 of a forming die, and the section 52 is moved towards the section 51 to deform the hoop to a generally rectangular shape with rounded corners and bulged sides. A punch 55 then descends to flare the edge of the hoop outwardly at 12a, Fig. 9, and the other edge inwardly into a recess 54. This latter edge is then formed into a flange 22a, Fig. 10, by die means 56, 57. The hoop is then inverted and the portion 12a formed into a flare 12b, Fig. 12, by a punch 70 co-operating with a vertically movable cushion plate 66 and spring- urged ring 68. The hoop is finally formed with a rib 12d and flange 12e, Fig. 14, by the punch 70 against a rigidly supported ring 88. In a modification, a single thickness hoop 112, Fig. 15, is brought to rectangular form and, by a chamfered punch 151 co-operating with a twosection die 152, is formed with a flare 113. The hoop is then formed with a horizontal inner flange 114, Fig. 18, by a punch 170 co-operating with a die 166 and spring-urged ring 168. A lip 115, Fig. 21, a rib 292 and outer flange portion 116 are then formed by an inner punch 191 co-operating with a spring-loaded plate 193 and by an outer spring-urged punch section 192 co-operating with a die 196 and outer ring 198. Specification 789,378, [Group XL (a)], is referred to.

Abstract: 522,553. Electric insulation. BUSHING CO., Ltd., and BROWN, W. J. Dec. 16, 1938, No. 36647. [Class 36] [Also in Group IV] Laminated insulating materials and bushing insulators are formed by superposing and bonding together layers of paper impregnated or coated with polystyrene resin. In making a bushing insulator, the impregnated &c strip may be passed between heated rollers, to which pressure is applied, to remove moisture and soften the resin, and then wound under tension on a mandrel &c. and finally baked; the mandrel may then be removed or be left in place. The paper may comprise pure cellulose or alpha-cellulose. To apply the resin it may be made into a varnish by solution in benzene, toluene, xylene, cyclohexanone &c. ; a miscible liquid with a higher boiling point, e.g., 10 per cent. of isopropyl benzene, may be added, and after applying, the paper strip is passed through an oven to volatilize the solvent. Before applying such varnish, the paper may be impregnated with styrene which is then polymerized by heat in an inert atmosphere. One or more layers of conducting material may be interleaved with the impregnated &c. paper.
