Title: Improved rotary engine
IPC: F01C21/00
Filed: 1943-09-08
Abstract: 571,291. Rotary engines. SPIES, V. J. B. Sept. 8, 1943, No. 14731. Convention date, June 26, 1942. [Class 110 (ii)] The engine driven by steam or other elastic fluid, comprises a casing C and a rotor R supported on one or more bearings 12 mounted eccentrically on a shaft S, and an outwardly-sliding or hinged abutment G arranged between the inlet and exhaust ports A, E. The abutment is pressed downwards by a spring plus the steady, or intermittent pressure of the working fluid. The rotor and abutment are each in two parts, spring-pressed apart with packing pieces inserted. Blocks W, which act as counterweights, prevent axial displacement of the ball race 12. Springs 14 act on balls 15 to press the ball race outwards to ensure the contact between the rotor R and the casing C. The abutment G has a bearing slipper 19. The inlet valve V is rocked by links connected to an eccentric on the shaft S, and may be adjustable. In place of the springs 14, radial rods may be forced outwards by a spring-pressed bar with a conical-shaped head, arranged within the shaft S. In a modification Fig. 5, a hinged abutment F is used in place of the abutment G. Working fluid acts on the back of the abutment. The abutment F may be in two parts with springs between, and may have a shoe 19. A further arrangement is as shown in Fig. 1, but with rotary inlet and exhaust valves which reverse their functions when an exterior lever is operated. A number of engines may be arranged on one shaft with inlet and exhaust ports arranged to secure balance. The cylinder C may rotate around a fixed part R.

Patent GB-769820-A (GB)
Title: Improvements in thermoplastic resinous compositions
IPC: C08L33/12
Filed: 1955-05-23
Abstract: A thermoplastic resinous composition comprises a homogeneous mixture of 100 parts of (1) a vinyl halide polymer of a monomeric material in which each constituent contains a single olefinic double bond and in which the predominant monomer is vinyl halide and 1 to 40 parts of (2) a hard resinous interpolymer of a mono-olefinic monomeric mixture comprising 75 to 25 weight per cent of a monomer consisting of styrene, nuclear-substituted styrenes or alpha-substituted styrenes, and from 25 to 75 weight per cent of an alkyl methacrylate, and containing not more than 20 weight per cent of other polymerized mono-olefinic monomers.  The vinyl halide polymer may be polyvinyl chloride or a copolymer of vinyl chloride with one or more of vinylidene chloride or bromide, vinyl acetate, propionate, butyrate, chloroacetate, chloropropionate, benzoate or chlorobenzoate, acrylic, chloracrylic, methacrylic or ethacrylic acid, methyl, ethyl, butyl, n-octyl, 2-ethylhexyl or n-decyl acrylate, methyl or butyl methacrylate, methyl or ethyl ethacrylate, acrylamide, methacrylamide, N-methyl or N,N-dimethyl acrylamide or methacrylamide, acrylonitrile, chloroacrylonitrile, methacrylonitrile, ethacrylonitrile, styrene, dichlorostyrene, vinyl naphthalene, dimethyl or diethyl maleate, vinyl methyl, ethyl, isobutyl or 2-chloroethyl ether, vinyl methyl, ethyl or isobutyl ketone, vinyl pyridine, N-vinyl carbazole, N-vinyl pyrrolidone, ethyl methylene malonate, isobutylene, ethylene or trichloroethylene.  The hard resinous interpolymer may be a copolymer of styrene, chlorostyrene, dichlorostyrene, vinyl toluene, alphamethyl styrene, or methoxystyrene and methyl, ethyl, propyl, isopropyl, isobutyl, isoamyl or isohexyl methacrylate.  The composition may also comprise a rubbery interpolymer of a monomer mixture comprising 50 to 90 weight per cent of a 1,3-butadiene hydrocarbon, 5 to 30 weight per cent of acrylonitrile or methacrylonitrile and 5 to 30 weight per cent of at least one other mono-olefinic monomer copolymerizable with the 1,3-butadiene hydrocarbon and the nitrile, such as styrene or an alkyl acrylate or methacrylate, the composition containing from 1 to 25 parts of rubbery interpolymer per 100 parts of (1) and (2). The composition may be made by blending powdered dry resins, by milling, by mixing solutions of the resins in a mutual solvent or mixing aqueous dispersions thereof, or by polymerizing the monomeric ingredients necessary for one resin and then adding the monomeric ingredients of the other and continuing the polymerization, e.g. vinyl chloride is polymerized in aqueous medium in the presence of caprylyl peroxide and a mixture of gelatin and bentonite clay, the excess of vinyl chloride vented, styrene, methyl methacrylate and further caprylyl peroxide added, and polymerization continued.  The composition may be used for the production of rigid rods, pipes and sheets.

Title: Movie camera
IPC: G03B21/43
Filed: 1975-04-10
Abstract: 1509556 Film winding mechanism NIPPON KOGAKU KK 10 April 1975 [15 April 1974 2 May 1974] 14837/75 Heading G2E A motion picture camera capable of performing overlap, superimposition, and reverse photography can accept either a film magazine in which the takeup shaft is inhibited against reverse rotation (type A), or a magazine having such inhibiting means but in which such means can be rendered inoperative so as to allow reverse rotation (type B), the camera having means for detecting which type of magazine is installed, and rendering the inhibiting means inoperative when a type B magazine is present. In Fig. 1, a type A magazine 1 is installed. The driving force is transmitted from a motor (not shown) to a winding gear 4 and thence via a pin 5 on the gear to a detector member 3 and a core 2 to take-up shaft (not shown). In this position normal photography, with forward rotation of the take-up shaft, can be carried out. For "overlap", the exposure is gradually faded out, the film rewound without exposure, and then run forward again while gradually fading in the exposure once more. This is effected by pushing down a control member 8, a gear 18 thereon being brought into engagement with a counter gear 19. The end 8b of member 8 also engages and pushes down a first connecting member 22, which has a bevelled end 22b. This engages and pushes to the right a second connecting member 25. At the same time a tooth 8a on member 8 engages winding gear 4 and locks it against rotation. The other end of member 25 actuates mechanism for gradually closing the opening angle of the shutter until it is completely closed. The parts are now in the Fig. 2 position. The counter indicates the length of film fed during this fade-out operation, in which the film is fed towards the take-up side by a claw, since the take-up shaft does not operate. The motor is now reversed, and the film is fed back to the supply side by the claw, the shutter remaining closed. The motor is again reversed so that the drive is normal forwards. Member 8 disengages from winding gear 4 and from the counter gear 19. The shutter gradually opens again and so the overlap exposure is completed. For "superimposition", member 22 is disengaged from member 25, so that the above sequence of operations is repeated without the shutter opening angle being altered. When a type B magazine is installed Fig. 3, the detector member 3 is forced into the magazine where it engages a part of the reverse motion inhibitor adapted to receive it, and renders it inoperative, so releasing the lock against reverse motion. In this position the winding gear 4 and control member 5 are not in the same plane, so that they do not engage, and gear 4 is not locked against rotation. Different embodiments of the mechanism are described with reference to Figs. (not shown) 4-12.

Abstract: 922,510. Sewing-machines. MEWA WEBEREI HAMELN G.m.b.H. April 28, 1960 [April 29, 1959], No. 15025/60. Class 112. In apparatus for hemming or sewing, the work material is fed through a sewing-machine by a feed dog at a predetermined speed, and is also conveyed to and from the sewing-machine by means provided with its own drive which is independent of the drive for the feed dog and which includes means for varying the speed at which the material is conveyed relative to said predetermined speed. For hemming coarse material the conveying speed is made less than the feed dog speed for tensioning the material. In Fig. 1 a sewing-machine 7, mounted on a stand 1, is driven from a motor 8 by a belt 9. A web 21 passes via a guide 22 and tensioning means 23 to a feed roll 10 in advance of the machine, and via a guide 24 to a puller feed roll 11. Rolls 10 and 11, which are respectively mounted on brackets 5 and 3 supported by struts 4 and 2, are driven by respective belts 12 and 13 from an infinitely variable gear-box 15, which is driven in turn by a motor 17. In Fig. 4 the work is conveyed to and from the machine between belts 32 and 36, belt 32 being driven from the gear-box 15. The edge of the work being hemmed rests on a work-table 35. Both edges of the work may be hemmed simultaneously by a pair of oppositely handed machines, or a series of progressively elongated machines may extend across the web. In an alternative arrangement the rollers 10 and 11 or the belt 32 are driven intermittently via a oneway clutch.
