Filed: 1964-03-30
Abstract: 1,060,843. Cine projection apparatus. PAILLARD S.A. March 30, 1966, No.21665/64. Heading G2E. In a cine projector for automatically projecting a plurality of substandard films in sequence, film spools 2, each with a hinged slotted cover 4 from which the film end projects, are coaxially mounted in a magazine 1 which is indexed laterally past projection lens 9 to permit the projection of each film. The film is wound on to hub 11 on shaft 13 driven through gear-box 21 by motor 22, the hub having a magnet which holds the magnetic end of the film being shown. At the end of the projection, the film tightens and moves a finger 42 to start a gear-box drive to spindle 23 whereby a push-rod tilts cover 4 to disengage the film from the claw mechanism in the projector body, screw 26 rotates once and screw and ratchet mechanism 28-29 indexes the magazine by one spool width, and pusher 15 displaces the film from hub 11 to reversely driven hub 14 on shaft 13. The film 13 then rewound on to its spool which has now engaged a continuously-driven wheel 25. A new film is now at the projection station and its end is engaged by the claw and is fed on to hub 11. The process repeats until all films have been shown. A manual control for ratchet device 28-29 allows the magazine to be indexed by more than one film if some films are to be omitted.

Title: Improvements in means for controlling elastic fluids
IPC: G05D16/18
Filed: 1918-12-30
Abstract: 140,855. Ionides, A. C. Dec. 30, 1918. Pressure - regulating- regulating valves. - A pressure-regulating valve apparatus tor maintaining a constant pressure relation between two elastic fluids, and of the type operated by a liquid-sealed bell &c. subjected to the outlet pressures of the two fluids, is fitted with means which, if one supply fails, allows the uncontrolled pressure of the other fluid to act on the actuator to close the valve controlling that fluid. The actuating-bell c dips into an annular tank e<3> of stamped metal supported by an annular casting e<4> provided with adjustable feet e<5>, and is connected to the double-beat air valve b and gas valve a by the system of links and levers described in Specification 110,568. The central domed part h of the tank, upon which the bell rests in its lowest position, is provided with a pipe j leading to the outlet side of the gas valve. If the air supply fails, the bell rises to close the gas valve and simultaneously moves a valve m to close communication between the pipe j and the outlet l. Further movement of the bell lifts a valve o seated in the valve m, against the action of a spring p, to open communication between the pipe j and inlet k by way of ports a<2> in the valve member a<1>, hollow spindle n, and ported plug m<2>. In a modification, the valve o is opened before the valve m is seated.

Abstract: 1,095,446. Bi-stable devices employing lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 24, 1965 [Aug. 31, 1964], No. 21807/65. Heading H1C. In a bi-stable device, two GaAs injection lasers 2, 4 are arranged so that when either is excited its output passes through, and thereby quenches, the other. As shown in Fig. 1, each laser comprises an optical cavity defined by a totally reflecting face 6 of SiO and Al and a partially reflecting (reflectivity <) face 8 of SiO, the sides 10, 12 having a non-reflecting quarter wave coating of SiO. Current is supplied through connections 17. To switch from the stable state in which laser 2 is excited, an external optical input 19 is applied to quench laser 2 thereby allowing laser 4 to lase. Since the output from the quenching laser is amplified by the quenched laser, it is possible to split the final output from face 12 to serve as inputs 19 for similar succeeding bi-stable devices. In Fig. 2 (not shown), the output from laser (2) passes without reflection through laser (4) and only one mirror (16) is provided to reflect the output from laser (4) through laser (2). In Fig. 5 (not shown), an absorbing layer (32) is included in the optical cavity between the totally reflecting surface (34) and the active region (30). In Fig. 6 (not shown), the reflecting faces (6, 8) are wider than the non-reflecting faces (10, 12) and lenses (36, 38) are used to converge the output.

Title: Improvements in or relating to burners for liquefied gas lighters
IPC: F23Q2/173
Filed: 1959-06-25
Abstract: 919,475. Liquefied gas lighters. NATIONALE S.A. June 25, 1959 [July 11, 1958], No. 21830/59. Class 75 (3). In a liquefied gas lighter comprising a member 6 adapted to apply pressure to a wick 7 soaked in liquefied gas and means for moving the pressuremember 6 relative to the body 1 of the lighter to vary the supply of gas to the burner, the pressuremember 6 has a surface 20 inclined to a surface 21 of the body 1 and movable elements, for instance balls 22, are placed between the inclined surfaces 20, 21 and are operated by an operating member 16 so that a movement of the balls 22 produces a movement of the pressure member 6 relative to the body 1. The operating member 16 is screwed into the body 1 and has a conical surface 19 engaging the balls 22. The pressure member 6 is returned in an upward direction by a resilient joint 13 disposed between conical surfaces on the pressure member 6 and the body 1. The lower end of the pressure member 6 has an aperture 10 for the flow of gas from the wick 7 to the burner and the flow therethough is controlled by a resilient pad 12 on the end of a rod 11 extending upwards through the pressure member 6 and the operating member 16. In a modification, Fig. 2 (not shown), the surface 20 of the pressure member 6 is planar and the inclined surface 21 is formed on the lower end of a sleeve which is threaded into the body 1 and into which the operating member 16 screws. A rapid adjustment of the pressure member 6 can be made by screwing the sleeve in or out of the body 1. In another modification, Fig. 3 (not shown), the balls 22 are replaced by pusher-rods which pass through holes in the body 1. The inner ends of the rods abut an inclined surface on the pressure member 6 and the outer ends of the rods abut an inclined internal surface on an operating member screwed on to the outside of the body 1. Instead of rods or balls wedges may be used.

Title: Liquid crystal cells
IPC: G09F9/35
Filed: 1976-05-26
Abstract: 1522065 Controlling light INTERNATIONAL BUSINESS MACHINES CORP 26 May 1976 [5 June 1975] 21833/76 Heading G2F To facilitate thermal addressing of a liquid crystal layer with an infrared (laser) beam, whereby the liquid crystal may undergo a phase change, a layer containing the reaction product between a nickel complex and a polyamide is disposed adjacent at least one side of the liquid crystal layer. Such a layer may have a high infrared absorbance and yet be virtually transparent to visible light. The use of two layers is desirable insofar as lower concentrations of product may be employed with less risk of crystallization and/or thinner layers can be used which are smoother and flatter. In addition heat diffuses into the liquid crystal layer from both sides for faster response. As described each layer is disposed on a transparent substrate, either covering or being covered by a transparent electrode layer used for erasure. The nickel complex may be a phthalocyanine, a bis(dithiobenzil) chelate, or bis(octa-4,5,dithione) nickel.

Title: Improvements in or relating to universal supporting means for mounting cinematographic cameras or other apparatus on aircraft
IPC: B64D7/02
Filed: 1933-08-09
Abstract: 424,002. Aircraft mountings for cameras &c. BOYSSON, J. B. A. DE, 6, Boulevard Ornano, Paris. Aug. 9, 1933, No. 22309. Convention date, Aug. 9, 1932. [Class 97 (i)] [See also Group XXI] A support for mounting cameras or other apparatus on aircraft comprises a platform rotatable in azimuth upon a ring fixed to the craft and carrying bearings in which the camera is mounted so as to be rotatable in elevation relatively to the platform, a double servomotor or two independent servo-motors mounted on the platform and controlling separately the rotation of the platform and the rotation of the camera in relation to the platform, and a single operating member for independently or simultaneously effecting the two movements. The platform 1 is carried by a ring 1<a> rotatably mounted on ball bearings 3 in a ring 4 fixed to the aircraft. Mounted on the platform are brackets 6 having bearings 7 in which is supported a frame 9 carrying the camera &c. 10. The platform also carries a seat 11 for the operator. The rotary movements of the platform and of the camera are effected by a double hydraulic generator 13 carried by the platform and having two outlets the discharges through which can be varied independently of each other. One outlet leads to a motor 17 connected to a gear-wheel 19 gearing with teeth 20 on the ring 4 so as to rotate the platform, and the other leads to the ends of a cylinder 21 containing a piston the rod of which is connected to the trunnion 8 of the frame 9. The controls 14, 16 for the two outlets are both connected to a lever 15 universally mounted on the platform so that lateral and longitudinal movements of the lever respectively control the azimuth movements of the platform and the elevation movements of the camera &c. The generator 13 may be driven by an electric motor 23. To prevent oscillation of the platform within the ring 4 and to neutralize the torque due to wind, a steadying device may be provided consisting of a plunger 25, Fig. 2, carried by a wheel 34 driven by the motor 17 and entering a liquid-filled cylinder 26 pivoted at 32 to the platform. The cylinder 26 communicates with a cylinder 28 having within it a deformable chamber 29 containing compressed air. Oscillations of the camera &c. in elevation may be prevented by providing at each end of the cylinder 21 a passage 43, Fig. 3, forming a byepass by which liquid can leave the cylinder when the ball valve 39 is closed. The flow through the byepass is controlled by a valve 44 biassed by a spring 45 and having varying cross-section throughout its length. Upward movement of the piston due to the admission of liquid through the passage 37 causes the pressure behind the piston to open the valve 44 until this pressure is balanced by the resistance of the spring 45.
