Patent GB-190479-A (GB)
Title: Method of and apparatus for plastically reproducing objects
IPC: G03F7/00
Filed: 1922-12-11
Abstract: 190,479. Engelmann, W. F. Dec. 11, 1922. Statuary and solid objects, reproducing.- Plastic reproductions of objects and parts of the human body are made by producing photographically a series of contour diagrams of the object and using the diagrams to direct the movements of a pantograph cutting apparatus. Two methods are described which differ in the manner of recording the form of the object and involve consequential modifications of the reproducing apparatus. First method. Photographs of an object 7, Fig. 1, are taken by a moving-picture, camera 8, the object being partially screened by cover 9, and illuminated by lights 10 placed in a plane perpendicular to the direction in which the camera is pointed and coinciding with the edge of the cover. The camera, cover, and lights are mounted on a ring 11 adjustable in a stand 12 by a worm 14 driven from a motor 17. The ring 11 is rotated through a small angle between the exposures, so recording a succession of lines of light and shade until a complete revolution has been made round the object. Further exposures may be necessary for the deeper parts of the object. The developed film is inserted in a projector 24, Fig. 2, an enlarged image 25 is thrown on a screen 26, and the tracing disc 27 of a pantograph 29 is moved around the image while a milling cutter 20 removes material from a block 19. The block and film are rotated intermittently by hand wheels 31, worm gearing 30, and a chain drive 34. One turn of the hand wheel rotates the block through the same small angle as in the successive exposures, and also brings a new image before the projecting objective. The cutter 20 is adjusted for any auxiliary exposures, and the raproduction is finished by smoothing out the ridges. Second method. The cover, lights, and camera are mounted on a carriage 40, Fig. 3, movable rectilinearly to and away from the object so that a series of parallel contours of light and shade are recorded. The back portion may be photographed by rotating the whole apparatus. The linear motion is obtained through a motor chain drive 52, worm gearing 49, 43, and a screwed shaft 42, which engages a tapped hole in the wheel 43. To reproduce the object, a tracer disc is moved around an image as before, and actuates a milling cutter by a pantograph. The block of material is mounted on centres, but is not rotated thereon; the table carrying the block is raised or lowered by worm gearing from which the film is driven by a chain. This method is applicable to the production of basreliefs by moving the table a fraction only of its normal feed.

[Class 110(iii)] [Also in Group XXXI] In a gas turbine plant for driving a locomotive the turbine comprises two stage rotors mounted on separate shafts. One stage drives the air-compressor and the other drives the locomotive wheels through a gear box comprising clutches and alternative gears for forward and reverse running. The power turbine is kept running when the locomotive is at a standstill and to reduce the idling speed of that turbine it is coupled to a permanent load. This load may be the locomotive accessories, other than those for the turbine plant, such as an air compressor or exhauster for the brakes and an electric generator. These auxiliaries may be driven by a continuation of the turbine shaft on the other side of the gear box. They may be driven by a shaft parallel with and geared to the drive shaft of a gear box as described in Specification 628,453. [Group XXIV]. The gear could be as described in the above numbered Specification.

Title: Coated capsules, particularly for use in photographic processes
Inventor: MCCUNE WILLIAM JAMES
IPC: G03C8/42
Filed: 1966-08-01
Abstract: 1,146,748. Micro-capsules. INTERNATIONAL POLAROID CORP. 1 Aug., 1966, No. 34458/66. Heading B8C. [Also in Divisions C7 and G2] Micro-capsules for use in photographic processes have their shells coated with elemental metal. The capsules may contain colour dyes, e.g. cyan dye developer. They have hydrophilic or hydrophobic polymeric shells and may have photosensitive coatings of a light reflecting coating, e.g. of aluminium. They may be used in two or three colour processes, see Division G2. The capsules, made by known means, may be coated by vacuum deposition, cathode sputtering, vapour deposition, and electro plating. In the last instance, the capsule wall is given an initial conductive coating, e.g. by vacuum deposition of metal, spraying or dusting on graphite or applying lacquers containing a suspension of metallic powder. In apparatus for vacuum deposition, a container 26 having internal axially directed fins 50 is rotated in an exhausted vessel 56 about a heated grid 20 which is coated with the metal to be deposited. The capsules 22 are tumbled in the vapour so formed to receive a uniform coat. In other metal vapour processes (not detailed) the capsules may fall freely through the vapour. In one method of encapsulating prior to coating, aqueous sols of hydrophilic materials, e.g. gum arabic and gelatine are mixed and a water immiscible organic liquid and colour providing substance are emulsified in the mixture. The emulsion pH is adjusted so that the ions of the hydrophilic materials have different electric charges. Encapsulation is achieved by dilution with water or modifying the pH of the mixture.

[Class 39 (i)] In an electron discharge device in which all the electrode leads pass through a base member of the envelope, the base member supports a metal tube in which are mounted a cathode, a control grid and an anode, all being planar and parallel, and which shields the anode lead from the other electrodes and their leads. As shown in Fig. 1, the planar electrodes 4, 5, 6, 7, 8 of a pentode are supported inside the metal cylinder 3 which is mounted on the base plate 2 of the envelope 1. The suppressor grid 5 is directly connected to the cylinder 3, the screen grid 6 is connected to the cylinder through byepass condenser formed by an insulating washer 13 and a flange 12 on the screen grid supporting disc 11, and the cathode 8 is connected to the cylinder through a byepass condenser formed by an insulating washer 17, the flanged base portion 16 of the cathode and a metal washer 17<1> contacting the cylinder. The anode lead 27 passing down the outside of the cylinder 3, and the other electrode leads passing down inside the cylinder, are sealed through the base plate 2. The electrodes and the members supporting them may be assembled in the cylinder 3 by pressing them together to form a composite electrode structure, Fig. 2 (not shown), the insulating washer 13 being extended to separate the screen grid supporting disc 11 from the suppressor grid supporting disc 10. Specification 445,087 is referred to.

Abstract: 308,646. Austin, Sir H. Dec 24, 1927. Bodies. - In a method of securing panels of sheet metal or sheet metal and plywood to road vehicles or other structures of the kind in which the panels are separated by a T-section member against which the bent edges of the panels bear and secured by channel members, the channel members may be formed with side channels or hollows which may be reinforced by wood fillets, or the channels may be drawn into close relationship with the T-section members by T-bolts each adapted to have its head engaged within an undercut slot in the web of the T-section member; the bolt passing through the base of the channel member. The flanges b, Fig. 1, of the sheet metal panels B are separated by a T-section member A, the half-round head a of which overlies the bent corners of the panels. Channels of the shape shown embrace the flanges b and the whole is secured by a bolt D, wooden fillets C being disposed in the channels C. A lining E is also provided. Instead of the bolt D the panels may be secured by means of a bolt K which is secured in the web of the member A by means of an aperture and a slot in the latter, as shown in Fig. 3. Fig. 4 shows the method employed for panels disposed at right-angles to one another, the reinforcing strip p being bent as shown. The reinforcing sheet metal channel may be replaced by a rolled or cast channel.
