Title: Improvements in and relating to methods of producing metal containers for fluids
IPC: B23B5/00
Filed: 1934-07-20
Abstract: 427,854. Making metal containers for fluids. KIDDE & CO., Inc., W., 60, West Street, Bloomfield, New Jersey, U.S.A. July 20, 1934, No. 21316. Convention date, July 20, 1933. [Classes 83 (ii) and 83 (iii)] In a method of producing metal containers 1 such as those used for storing fluids under pressure from a tube having at least one open end which is necked in at 2 to receive a plug, the internal surface 4 of the container wall is machined by a cutter inserted through the neck, the external surface 7 of the container serving as a datum surface for controlling the machining. The cylinder may be made by cupping a blank by successive drawing operations to form a closed cylinder and then machining internally and externally to the required thickness before necking-in the open end. The neck is bored to a predetermined diameter and the external surface is machined to provide the datum surface 7. The internal machining device comprises a shaped guide collar 9 conforming with surface 7 and receiving a ring 10 and coupling 11. The coupling is bored to receive a bushing 14 threaded in a nut 16 and also in a micrometer nut 19 which bears against a thrust ring 20 coacting with ball bearing 21. The bushing is bored to receive the end 25 of boring-bar 26 which fits in the neck 6 and in a groove 27 of the bushing. The other end of the bushing receives a push-rod 28. A sleeve 33 slidably keyed to the bushing is connected by a safety shear-pin 37 to an adapter 35 which receives the end 46 of the push-rod. A screw 53 located in a slot 52 prevents rotary movement of the push-rod. The boring- bar carries a holder 55 for a tool 57 the holder being pivoted at 56 and connected by a pivoted link 62 to the push-rod extension 29. In operation, the container may be mounted in a lathe spindle and the adapter secured to the turret. The tool is set so that its edge describes the required radius from the pin 56. The nut 19 is then set so that the required depth of cut is taken and the turret fed forward to advance the push rod and move the tool around its pivot to take a cut from the shoulder 4. After return of the tool a second cut may be taken by rotating the nut 19. The tool may be employed for machining the inside cylindrical surface of the container by advancing the boring-bar after the tool has been swung out into contact with the side wall. By mounting the tool so that it may swing outwards beyond the end of the boring-bar the bottom of the container may be machined. In order to machine a surface which is not circular in section the swinging movement of the tool may be combined with templet-controlled axial movement of the boring-bar or of the pivot 56.

Title: Improvements in or relating to the production of colored talking picture films
IPC: G03B31/04
Filed: 1931-07-28
Abstract: 376,514. Optical sound recording apparatus associated with kinematographs; combined sound and picture records. MULTICOLOR, Ltd., 7000, Romaine Street, Los Angeles, U.S.A. July 28, 1931, No. 21539. Convention date, July 28, 1930. [Class 40 (ii).] Comprises a method of optically recording sound on colour-picture films of the kind in which the positive picture film has differently coloured images on the opposite sides thereof and a sound record on one of the sides. As shown in Fig. 1, a film magazine 13 is mounted on the main casing 12 of a camera 11 and a uniformly-driven sprocket 21 is adapted to feed a pair of colour-sensitive negative films 22, 23 from the magazine 13 to the picture photographing mechanism 14. The film 22 is bluesensitive and the film 23 red-sensitive, these films receiving the blue-green and yellow-red colour images respectively. The picture-recording light rays pass first through the bluesensitive negative 22. After leaving the photographing apparatus 14, the negatives 22, 23 are carried to the lower portion of the sprocket 21 from whence the red-sensitive film 23 is carried upwardly around the right-hand portion of the sprocket 21 back to the magazine 13. The blue-sensitive film 23, however, is carried from the lower part of the sprocket 21 in a loop over rollers 26, 27 to the sprocket 28 from which it is carried upwardly to the magazine 13 in contact again with the red-sensitive film 23. Within the loop 36 formed by the film 22 is placed an optical sound-recording system comprising a tube 40 which houses a glow discharge lamp 41 and a quartz disc 44 whose outer surface conforms to the curvature of the film 23 as it passes around the sprocket 21. The glow discharge lamp is operated by current which is varied in accordance with the sound oscillations to be recorded. The inner face of the disc 44 is coated with a layer of silver 45 on which is made a horizontal scratch 46, Fig. 2, to form a light slit for the recording of sound upon a sound-record track 50 on the film 23, which track has been left unexposed by the picture camera. The corresponding strip 50 on the blue-sensitive film 22 also remains unexposed so that when the colour-sensitive films are subsequently developed the strip 50 of the blue-sensitive film 22 will be clear, while that of the red-sensitive film 23 will contain a photographic record of the sounds. When these co-operative negatives are subsequently employed for the printing of a colour positive, the sound record will appear at the side of only one emulsion coating of a double emulsion film.

Title: Machine for the production of moulded articles
IPC: B29C41/04
Filed: 1954-07-23
Abstract: 755,475. Rotary-mould machines for making articles from pulp or resins.. PETERSEN, J. A. July 23, 1954, No. 21596/54. Class 87(2) A machine for moulding thermoplastic or thermosetting materials or for moulding fibrous articles from pulp comprises an outer frame 4 fixed on a shaft 1 which rorates clockwise through each of the four positions shown. The frame 4 carries four mould elements 5a, 5b, 5c, 5d which cooperate with four complementary elements 8a, 8b, 8c, 8d movable radially towards and from shaft 1 by plungers 7a, 7b, 7c, 7d slidable in cylinders 6a, 6b, 6c, 6d rotatably mounted on shaft 1. In making articles from pulp the machine is set to rotate continuously and a tank 15, which may contain wood pulp, is suspended under the shaft 1 within the frame 4. A tray 27 is mounted on the shaft bearings for the removal of ejected articles by gravity. In operation, and considering only the mould parts 5a, 8a, before mould element 8a enters tank 15 fluid is withdrawn from cylinder 6a via pipe 9a so that tension spring 29a withdraws mould element 8a from its extended position until it abuts the cylinder 6a. The element then enters the tank 15 and air pressure is reduced in the element 8a so that a wet fibre mass is deposited on it and is subsequently carried with the mould element until it has passed the 12 o'clock position whereupon element 8a is moved into contact with the element 5a at the 3 o'clock position. Air pressure is increased in element 8a via conduit 11a, and reduced in element 5a via conduit 12a, so that the fibre article is transferred from element 8a to element 5a. Element 5a then carries it from the 3 o'clock position to the 6 o'clock position, while another fibre mass is deposited on mould 8a, and on to the 12 o'clock position where it is above tray 27, whereupon air pressure in element 5a is increased, via conduit 10a to eject the article on to the tray. Thus, the deposited mass is subjected to dewatering during 1“ rotations of the machine.. In moulding thermoplastic substances, e.g. to make gramophone records, the mould elements rotate stepwise and the material may be fed when the mould element is in its bottom position after which it is cooled while it moves to the 12 o'clock position where the finished blank is removed. The mould element is then heated, e.g. by steam, while it continues its rotation to the bottom position. In moulding thermo-hardened artificial substances the mould elements may be electrically heated, the wires to the heating elements being led through channels in the. shaft and the material may be fed at either the bottom or the 12 o'clock position. In pressing thermoplastic or thermosetting material the cylinders may be connected to the outer frame by columns.

Filed: 1938-07-23
Abstract: 517,232. Charging and discharging batteries. ASSOCIATED ELECTRIC VEHICLE MANUFACTURERS, Ltd., and LEE. A. F. July 23, 1938, No. 21871. [Class 38 (iv] . Two batteries are charged in turn under the control of electrically interlocked contactors 2, 3 so that one only of the batteries can be charged at a time and when fully charged, as determined by a relay which opens when a predetermined number of ampere-hours of charge has been given, the battery is cut off supply and the second battery automatically connected thereto. In the arrangement shown two batteries 4 and 5 and their associated ampere-hour meters 25 are adapted for connection to a panel 1 by means of three-pin plugs and sockets. The supply to the panel from A.C. mains 20, 21, through transformer 22, rectifier 23 and a further three-pin plug and socket, is controlled by a main contactor 33 in the primary circuit of the transformer. If, sav, battery 4 is the first to be connected current from it closes contactor 2 which completes a closing circuit for contactor 33 so that the battery is placed on charge. If, now, battery 5 is plugged in, contactor 3 is prevented from being closed to place this battery also on charge by auxiliary contacts 7 on contactor 2 which are open when contactor 2 is closed. When battery 4 has received a predetermined charge, normally-closed contacts 26 are opened by the ampere-hour meter, contactor 2 opens, and charging ceases. Auxiliary contacts 7, however, are closed with the opening of contactor 2 so that contactor 3 closes to place battery 5 on charge. Finally, when both batteries have been charged the charging apparatus is shut down.
