Abstract: 435,859. Copying images on lenticular films. OPTICOLOR AKT.-GES., Glarus, Switzerland. March 1, 1934, No. 6604. Convention date, March 23, 1933. Addition to 421,084. [Class 98 (ii)] In copying from a lenticular film onto a lenticular blank film by optical projection as described in the parent Specification, the film gates and the objective are maintained stationary and plane reflecting surfaces arranged between the objective and the films are moved so that the aperture of the system is seen from the films successively in different directions. In this way an optical system of small relative aperture may be employed. Figs. 2 and 2<1> show diagrammatically a film 1 which is copied on the film 4 by the objective 2 and pairs of mirrors 16, 17 and 18, 19. As shown in Fig. 2, the central image under each lenticular element is being copied. By moving the mirrors equal distances in opposite directions as shown in Fig. 2<1>, one set of lateral images may be copied. In the arrangement shown in Fig. 5, the films 1, 4 are fed through gates 5, 7 by a common drive 37. Prisms 28, 29 are arranged on either side of the objective 2 and light from film 1 passes by way of prisms 27, 28, objective 2, and prisms 29, 30 to film 4, the prisms 27 and 30 being mounted on a reciprocating carriage 35 driven from the shaft 37 by a cam 36. In a modification, Fig. 3 (not shown), three angular mirrors arranged in staggered relationship one above the other and moved vertically are used. In further modifications, additional mirrors to correct lateral inversion are employed. Such a mirror is shown at 53 in Fig. 5. In a form described but not claimed, mirrors are not used, the film gates themselves being reciprocated on opposite sides of the objective. Specification 430,503 is referred to.

Abstract: 1,199,166. Valves. ABEX INTERNATIONAL S.A. 2 Oct., 1967, No. 44799/67. Heading F2V. [Also in Division F1] The output of a rotary positive displacement pump 11 is fed through a duct 33 to one side of an orifice 18 which co-operates on its other side with a conical throttle 16 which is urged towards the orifice by either spring or fluid loading means. Throttle 16 is formed on a piston 17 which has a by-pass orifice 22 through which fluid in chamber 23 can pass to reservoir 28 via chamber 21 and passage 25. As described the valve is used to control the speed of a wire drum carried by the pump rotor, the valve providing a variable braking effort which results in a constant linear speed for the wire regardless of the effective diameter of the wire on the drum. The required degree of braking effort is predetermined by the pressure applied through pipe 39. To enable wire to be wound back on to the drum, pipe 39 is switched to exhaust, and pressure is applied to pipe 40 to open valve 36 and operate the pump in reverse as a motor.

Abstract: 1,160,882. Arc blow-torches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 24 Oct., 1966 [25 Oct., 1965], No. 45096/65. Heading H5H. The unsymmetrical working of a plasma torch on A.C., normally resulting in increased electrode wear, is deliberately exaggerated by suitable selection of electrode materials and spacing in relation to the composition and rate of flow of plasma-forming gas so that electric arcs are struck only during similar half-cycles and the electrodes have the low-wear characteristics usually associated with plasma torches operated on D.C. For example, a pilot plasma is formed by injecting argon at 50 p.s.i. through inlet 14 and applying a rectified voltage between electrodes 10 and 2; nitrogen at 45 p.s.i. is fed through inlet 9 and forms the main plasma with unidirectional current flow from A.C. source 17 to electrodes 2 and 3. The electrodes 2 and 3 are of copper and the extensions 13 and 8, as shown, of thoriated tungsten, spaced respectively 9/ 32  inch and 5/ 32  inch from electrodes 2 and 3, and inlets 9 and 14 are of the order of 0À05 inch. The plasma may be used as a conductive column for transferred working on an electrically conductive workpiece or charge by making connections as in Figs. 2 or 3 (not shown). Two torches may be used to take full-wave current from the supply by cross-connection (as in Fig. 4, not shown) or by using a tapped transformer (as in Fig. 5, not shown), and the corresponding connections for transferred working are as in Figs. 6 and 7 (not shown). Transferred working without a fixed connection to the workpiece may be obtained by using four torches co-operating in pairs as indicated in Fig. 8 (not shown), or, for three-phase working, six torches as in Fig. 9 (not shown).
