Title: Improvements in or relating to the production of sound films
IPC: G11B7/00
Filed: 1930-12-23
Abstract: 375,766. Optical sound-recording apparatus. SIEMENS & HALSKE AKT.- Ges., Siemensstadt, Berlin. Dec. 23, 1930 No. 38741. Convention date, Dec. 24, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] In recording sound by means of a system projecting an optically reduced light beam upon a film, a monochromatic source of light is used, or optical filters are provided which confine the wave-lengths of the light employed to a very narrow band. This enables the effective width of the slit to be made very small (e.g. 5Á). Further, by using light of very short wavelength, or ultra-violet rays, chromatic aberration and diffraction effects, as well as diffusion in the light-sensitive layer, are avoided. Suitable light sources are sodium or caesium vapour lamps, or a cadmium or mercury vapour lamp used in conjunction with a light filter which absorbs all but ultra-violet rays. When a recording oscillograph is used with ultra-violet rays, the mirror must be of such a metal (other than silver) as will reflect the rays, and the damping liquid must be such that the rays are not absorbed. Castor oil is suitable. If the liquid is to serve as a light filter, a dilute solution of p-nitrodimethylaniline in glycerine may be used. The aperture is made of quartz or " uviol " glass.

Title: Improvements in or relating to a spray gun using high pressure coating material
IPC: B05B9/01
Filed: 1963-10-04
Abstract: 1,016,726. Spray-producers. DE VILBISS CO. Oct. 4, 1963 [Oct. 8, 1962], No. 39278/63. Heading B2F.  In an airless spray gun the trigger 50 may be locked against inadvertent activation by a spring-loaded threadedly operated member 82 and quick make-and-break of the valve mechanism 22 is effected by the use of apparatus including a valve body 28 which is slidable within a passageway 32 and carries a hemispherical valve surface 30 which abuts, in the shut-off position of the mechanism 22, a hemispherical seat 40 formed at the inner end of a seat member 38 in direct communication with the gun nozzle 24. The valve body 28 is connected through guiding vanes 36 to a valve rod 44 which extends through a retainer 48 to the trigger 50. The rod passes through a slot 52 in the trigger and a contact shoe 54 and terminates in a flange 56 and plastic bumper 58 which are located in a recess 60 of a collar 62 the latter being held in a spring passage 64 by the shoe 54 and acts as a retainer for a spring 66 therein. The spring is located around a rod 68 and is held in adjustable compression by a threaded spring retainer 70. When the trigger is initially pulled the shoe 54 pushes the collar 62 against the spring 66 to separate the bumper 58 and the end of the recess 60. On moving the trigger further the shoe 54 engages the flange 56 and moves the rod 44 rearwardly. The instant this happens, and the surface 30 moves from the seat 40, the high pressure coating material, pumped through a line 12, moves therebetween and instantaneously exerts a rearward force on the body 28 through the surface 30. Initially, the force of the material between the seat member 38 and the surface 30 causes the body 28 to move rearwardly faster than the trigger 50 can be pulled which results in the rapid valve action and eliminates spitting. The excess speed of the body occurs until the bumper 58 contacts the end of the recess 60 again and the trigger 50 catches up with the shoulder flange 56. Locking of the trigger 50 through activation of the member 82 allows safe removal of the nozzle cap 26 for cleaning &c. even when the gun is charged with pressurized material from a source 16.

Abstract: 909,771. Shoe upper conforming machines. BRITISH UNITED SHOE MACHINERY CO. Ltd. (United Shoe Machinery Corporation). Dec. 16, 1958 [Dec. 19, 1957], No. 39565/57. Class 17 (1). A machine for lasting the toe portions of an upper on a last L has wipers 10, a heel support 24 for the last, means to adjust the support widthwise and heightwise, means co-operating with the support to yieldingly position the toe with the plane of the feather edge parallel with the operating plane of the wipers, means to hold the last against turning about heightwise and lengthwise axes, means to guide the support from loading position to present the toe in predetermined relation to the wipers, and a member 12 to engage and locate the forepart of the shoe. The support 24 carrying the last pin 22 is pivoted at 26 in a yoke 30 slidable on parallel bars 32 along a path parallel to the line Y, Fig. 2. Bars 32 are secured to arms 38 and are adjustable heightwise about a horizontal axis at the focal point of the wipers by means of bolts 40 secured to arms 38 and adjustable in arcuate slots in brackets 42, scales 48 indicating the adjustment. Brackets 42 are secured to a bracket 46, and the bars 32 are adjustable about a vertical axis at the focal point by means of arcuate slots 50 in bracket 46 through which pass screws 52 secured to the frame. A triangular block 60 integral with a pivoted arm 62 is urged upwardly by a spring 64 into a triangular slot in the frame to form ways 66, 68 in which engages a pin 70 carried by bracket 46 and movable along a radial slot therein. When the pin is at the apex of the ways the last is centrally arranged with line Y in the median plane M, but movement of the pin in way 66 or 68 by means of the adjusting screw 80 causes the bracket 46 to move laterally to offset right and left lasts respectively. The adjustment of the pin is indicated on a scale, and the pin is moved from one way to another, to change from right to left shoes or vice versa, by depressing block 60, swinging bracket 46, and then returning block 60. Rotation of the last is prevented by engagement of a pin 88 carried by the support 24 in a hole 90 formed in a heel cone plate 86 secured to the last. An adjustable spring 94 permits the forepart of the last to be depressed manually while locating the last so that the hold-down 92 fits against a rib R on the insole, and an adjustable stop-screw 98 then assures that the forepart is correctly positioned for wiping. Yoke 30 is locked to rods 32 by spring- pressed pawls engaging teeth 120 on the rods 32 when rods 100, associated with the heel band operating mechanism, are moved rearwardly to lock the shoe in position, but the pawls are withdrawn by means of cables 108, 110 when rods 100 move forwardly to unlock the shoe. Each rod 32 is associated with three pawls, and the teeth of adjacent pawls are advanced one-third of the pitch of teeth 120. Specification 520,194 is referred to.

Abstract: 887,780. Gas-turbine plant. PLESSEY CO. Ltd. Nov. 14, 1960 [Nov. 26, 1959], No. 40216/59. Class 110 (3). A fuel control arrangement in a gas-turbine fuel system having a fixed displacement pump driven by the engine which, acting alone, would yield a fuel flow proportional to engine speed comprises two dump outlet paths each controlled by a metering orifice and a flowresponsive valve which up to a predetermined first rate of flow from the pump permits escape through both metering orifices and then, up to a predetermined higher rate of flow, progressively cuts off the escape path through one of the metering orifices whilst leaving the fuel escape path through the other metering path unaffected. A gear pump 1 draws fuel from a tank 2 and supplies it to the engine burner 6 through a valve assembly 4 and governor speed-control 5. The valve assembly 4 is an acceleration control and comprises a flowresponsive valve 7 and two needle valves 8, 9. The valve 7 comprises a spring-loaded piston 10 which separates, except for metering apertures 11, an inlet chamber 12 and outlet chamber 13. The chamber 13 has a permanently open port leading port needle valve 8 to the fuel supply 15. A second port 16 controlled by the piston 10 leads to the needle valve 9. When fuel is delivered by the pump 1 the pressure drop across the metering apertures 11, which varies with the rate of flow, will tend to move the piston 10 against the action of spring 17. At a predetermined rate of the flow the piston 10 will move and start to close the port 16 until at a higher rate of flow the port 16 is shut off. This will cause an increase in the rate of increase of fuel flow against speed which is necessary if the engine is to have maximum acceleration without overheating.
