Title: Improvements in conveyors for sheet material
IPC: B29D30/46
Filed: 1954-04-09
Abstract: 750,659. Sheet-delivery apparatus. FIRESTONE TIRE & RUBBER CO. April 9, 1954 [April 9, 1953], No. 10483/54. Class 100 (1). [Also in Group XXX] Trapezoidal sections 10 of tyre ply stock, after they have been bias cut, are fed by a conveyer 11 comprising endless chains 13 and a flat bed 12 to one or more rolls, e.g. rolls 26, 27, with their front edges 23 preferably perpendicular to the arcs of the rolls, and the rolls turn the sections and deliver them on to either of two lower conveyers 22, 34 such that the edges 23 become the side edges, and the sections 10 are then ready for the splicing operation. The conveyer 11 can be adjusted angularly relatively to the rolls 26, 27 to suit the bias angle of the stock, and the chains 13 are driven by a motor 18. The two rolls are located below the plane of the bed 12, are geared together, and the roll 27 is driven by a motor 32. A manually-operable switch located below the rolls determines on to which lower conveyer the sections 10 will be deposited. The roll 26 may have a plain smooth surface, and the roll 27 may comprise a rotary brush, but two smooth, or two rubber-covered rolls may be used. In a modification, one roll co-operating with a curved guide may be used.

Paper and like materials treated to imitate lace; fabrics composed of threads united by adhesives; compound sheet materials.-Relates to a method of manufacturing a non-woven fabric formed of crossing threads, and consists in winding two crossing sets of adhesive threads in spiral manner around two longitudinal travelling blades so that, when one set of threads lies across the top of the blades, the other set of threads lies across the bottom of the blades. The machine for making such fabric comprises a suitably-mounted rotatable disk 1 having thereon two sets of spools 4 which supply threads to oppositely-disposed sets of reeds 6, 7 mounted on the disk 1 and arranged respectively transversely and longitudinally of the axis of the machines. The two sets of threads from the reeds 7 are wound by the rotation of the disk 1 around two travelling blades 8, 9, which are guided over suitable rollers 10 and limit the width of the fabric. The fabric is cut from the blades by circular knives 11 and may be compressed by rolls or passed between sheets of adhesively-coated paper to form packing-material. The blades may be provided with teeth to retain the threads in position.

Patent GB-194573-A (GB)
Title: Improvements in and relating to hoisting gear
IPC: B66D1/22
Filed: 1922-04-13
Abstract: 194,573. Liardet, A. A., and Berk, F. W. April 13, 1922. Driving-gear for winding and paying- out apparatus; self-sustaining gear; stopping automatically at end of run; regulating and control-transmitting gear.-Comprises two constructions of hoisting-gear, for operation by hand and power respectively, of the type in which the drum is driven through epicyclic gearing fitted with two brakes or with a brake and a pawl-and-ratchet device. Fig. 1 shows a two-speed hand-actuated gearing employing one brake and a pawl and ratchet. The driving shaft A can be moved axially to bring alternatively - acting sun pinions D<7> into engagement with double planet pinions D<3>. By applying the weighted band brake D<8> to prevent rotation of the planet pinions, the drum D is rotated through a plain or compound spur drive for hoisting. Pawl-and-ratchet mechanism C<1> prevents the shaft A from running in the reverse direction, so that when the brake is released, the load runs down by gravity and rotates the gearing as a whole round the fixed sun pinion. A pivoted lever engages-one or other of the notches A<2>, A<3> to secure the driving-shaft in its adjusted position for each speed. Figs. 4 and 5 show power-driven gearing arranged for a continuously-running motor and fitted with interlocked brakes. The gearing is arranged on an intermediate shaft A connected by spur gear to the drum shaft D<x>. In this case the planet pinions form the driven members communicating movement to the drum, and braking of the planet pinions by means of the band D<8> stops the drum and sustains the load. When a brake D<9> is applied to a loose ring, the planet pinions are rotated for hoisting. The brakes are interconnected so that they cannot both be applied simultaneously, but both can be released at the same time. When both brakes are released, the load runs down by gravity. For controlling the two brakes, a shaft G, Fig. 5, can be rocked to either side of the mid-position illustrated. Rocking in either direction releases the brake D<8> by raising the weighted lever L through the medium of the double lever G<1>. On the other hand the brake D<9> is tightened through the medium of the crank arm F' when the shaft is rocked clockwise, and released when it is rocked anticlockwise. Specification 135,358, [Class 103 (i), Brakes &c.], is referred to. A stop operated by the moving load may be linked to the brake lever to return it to mid-position.

Title: A process for regenerating and deodorising alkaline washing solutions
IPC: C10G19/08
Filed: 1963-03-18
Abstract: Alkali washes of petroleum distillates, containing mercaptides, are regenerated and deodorized by oxidizing with sulphur, separating the disulphides formed, and treating the residual liquor with air or other gas comprising free oxygen at 50-120 DEG  C. and 0.5-4 atm. pressure to oxidize any remaining organic sulphur compounds and the inorganic sulphur compounds formed.  Amines with one or more amino groups, e.g. isopropylamine, may be used as an oxidation promoter for the oxidation with sulphur.  The sulphur may be added as a suspension in water, in which a wetting agent, e.g. one based on alkyl phenol polyglycol ether and ethylene oxide may also be present.  Steam may be added to the air for the second oxidation.

Title: Composite cinematography and television

Filed: 1975-03-14
Abstract: 1496016 Television MAGICAM Inc 14 March 1975 [15 March 1974] 10775/75 Heading H4F [Also in Divisions B7 and G2] A composite display system for television or cinematography has a camera 40 for foreground objects 36 and a camera 60 for background objects 62, the images formed by the two cameras being combined, and the cameras being movable to view the respective objects from different perspectives, wherein the movements of the cameras are so combined that they always view the objects from corresponding perspectives. Camera 40 is movable on a dolly 42, (see Division B7), horizontal movements of which produce signals representing components of movement in perpendicular X and Y directions. A boom 45 is pivoted at one end to the dolly about a horizontal axis to change the height of camera 40, mounted at the other end. Signals are produced representing the height of the camera, and also the horizontal component of its movement for combination with the horizontal dolly movement signals. The signals comprise a component representing movement and a component, to be integrated, repersenting rate of movement. Additional signals may be generated representing angular movement of the camera (tilt and pan), and allowance may be made if the axes of these movements do not pass through the nodal points of the lens. Camera 60 has its optical axis vertical, and has a tiltable and rotatable mirror 65 for viewing background objects 62, the mirror being also movable vertically. Camera 60 is movable horizontally on crossed carriages 72, 78. Signals for the movements of camera 60 and mirror 65 are generated, and may be scaled up if, as shown, the background objects 62 are modelled to a scale reduced with respect to the foreground objects 36. The signals from both cameras are fed to a control box 56 and an electronic servo control 58 so that camera 60 is slaved to camera 40 in such a way that the images of the cameras always present corresponding perspectives. Where, as shown, the cameras are television cameras, the images are transmitted via a video control 54 to a monitor 54a and a video tape recorder 54b. The combined image shows the image of foreground objects 36 in front of the background objects 62.
