Title: Flexible metallic tubes
Inventor: EDWARDS ARTHUR DESMOND
IPC: B21D15/04
Filed: 1954-12-28
Abstract: 769,728. Making corrugated tubes. ACCLES & POLLOCK, Ltd. Nov. 28, 1955 [Dec. 28, 1954], No. 37445/54. Classes 83 (2) and 83 (4). A method of forming flexible metal tubes having helical corrugations comprises feeding a cylindrical tube on to a mandrel having a helically grooved periphery and operating intermittently upon the exterior of the tube supported on the mandrel with swages having ribs complementary to the grooves in the mandrel. In an embodiment the grooved mandrel 4 is supported at the end of a rod 6 around which the tube is fed. Surrounding the mandrel are ribbed semiannular swages 8, the lower swage being fixed and the upper swage being intermittently movable radially relatively to the mandrel. Means (not shown) are provided for rotating the tube to feed it on to the mandrel and due to the cross-sectional form of the mandrel groove and the complementary ribs on the swages the corrugations are gradually formed on the tube without unduly stretching the tube wall. The mandrel groove may extend through only part of a helix or the groove may be interrupted by providing longitudinally spaced grooved sections 4a and intermediate plain sections 4b (Fig. 2). The swages consequently have ribbed sections 8a and intermediate plain sections 8b. The mandrel and swages may be formed in one piece or by adjustable sleeves detachably connected, the mandrel sleeves being secured upon a central spindle. The flexibility of the corrugated tube may be further increased by constricting the corrugations as shown in Fig. 3 by feeding the tube on to a mandrel 10 and radially compressing the corrugations with a swage 12.

Abstract: 904,275. Extruding. SCHLOEMANN A.G. Nov. 1, 1960 [Nov. 13, 1959], No. 37467/60. Class 83 (4). An hydraulic extrusion press has an axially movable billet container 10 which, during extrusion, is pressed against the die 9 supported through one or more pressure pieces 8, 4, 3 by the bolster 1, 2, and spherical surfaces 13 are provided on the bolster plate 2 and adjacent pressure piece 3 with their centre of curvature 14 in the entrance place of the die. Piece 3 is pressed towards the bolster by a flange 15 biased by cup or disc springs 17. A seal 20 prevents dirt entering the spherical joint. For extruding tubes a mandrel 12 is used inside the press ram 11. The die 9 and pressure-piece 4 are mounted on transversely movable slides 7, 5, respectively.

Title: Photographic Diffusion Transfer Process
IPC: C08G2/00
Filed: 1966-08-23
Abstract: 1,159,985. Photographic processes. INTERNATIONAL POLAROID CORP. Aug.23, 1966 [Aug.25, 1965], No.37745/66. Heading G2C. [Also in Division C3] A photographic diffusion transfer process comprises the imagewise transfer of imageforming components, as a consequence of development, from an exposed silver halide to an imagereceiving material via a contiguous layer of alkaline processing solution, the solution having pH greater than 11 and containing a polymeric material which is in solution but is precipitated on reduction of pH, and reducing the pH to between 7 and 11 which causes the layer to adhere to the image-receiving material. Alternatively, the alkaline processing solution may act as the imagereceiving material and this layer is solidified after reducing the pH and the solidified layer is left adhering to the silver halide emulsion if the process is performed as set out in Specification 714, 412. Specified polymeric materials are phenol-formaldehyde resins, polyvinyl acetals, polysulphonamides and polyhydroxymethylene. The diffusion transfer process is generally the dye developer transfer process but may be the silver salt diffusion transfer process. In the examples an image-receiving sheet (similar to those Specification 1, 071, 086) comprising a cellulose nitrate support coated with various polymeric layers including a layer of a partial butyl ester of an ethylene/maleic anhydride copolymer (which reduces the alkalinity of the processing solution) is contacted with an exposed silver halide emulsion with an alkaline processing solution containing one of the polymers specified above between the emulsion and the sheet and then separating the image-receiving sheet containing the dye image with the processing layer adhering thereto; its alkalinity having been reduced by the copolymer layer in the image-receiving sheet so that it adhers thereto. Alternatively, the alkalinity may be reduced by adsorption of carbon dioxide from the atmosphere. The adherence of the processing layer enhances the density of the dye image as not all the dye is transferred to the image-receiving sheet.

Title: Forming metal plate
IPC: B21D5/01
Filed: 1974-08-29
Abstract: 1424317 Shaping hot plates; making dies ALUMINUM CO OF AMERICA 29 Aug 1974 [9 Nov 1973] 37851/74 Headings B3A B3Q and B3V A heated plate is formed between dies by the weight of the top die, the plate being heated initially to a temperature below that at which grain boundary melting occurs and when first contacted by the top die being at a temperature at least high enough to maintain spring back at less than # inch in 25 feet if the plate after forming were allowed to cool naturally between the dies to 125 F., after forming the top die bearing on the plate with a pressure up to 100 pounds per square inch and the plate being retained between the dies until the time and temperature history following lowering of the top die is such that springback is less than # inch in 25 feet upon opening the dies. The process may be applied to forming aluminium alloy plates subsequently welded together to form spherical tanks for liquified natural gas; boat hulls also may be formed. Higher than the minimum contact temperature may be used with shorter cooling times; coolant may be insulated through the dies. In one arrangement, Fig. 2, after being heated to a maximum of 930 F. in a furnace the plate 6 is transferred to the male die 3 and moved on rails beneath the female die 5 which is lowered by hoists 7. The plate is at not less than 800 F. when the female die 5 is lowered and is left between dies until its temperature is 400 F. Alternatively, Fig. 5 (not shown), the plate is heated between the dies by flame jets in the upper die or by radiant heating. In another use the initial temperature was 920 F., contact with the upper die was above 800 F. and cooling time to 400 F. was 1 hour 30 minutes. Another initial temperature is 925 F. and a range of contact temperatures is 800-825 F. Plates of tapering thickness may be formed. Die construction of the male die is by casting calcium aluminate cement over ribs welded together in the form of an eggcrate. The cement is cast on to a bottom plate in each cell, and a pole at the centre of the die mounts a turn post from which extends a screed whose lower surface defines the spherical periphery of the die. Anchor clips for the cement we welded to the framework, and cooling pipes are included for use during or after shaping a plate. The female die is also of eggcrate construction, the cement beng cast through the cells on to a rubber sheet supported on the male die.
