Title: Improvements relating to apparatus for making flexible metal tubes
IPC: B21C37/12
Filed: 1947-12-09
Abstract: 649,781. Making flexible tubing. CHICAGO METAL HOSE CORPORATION. Dec. 9, 1947, No. 32514. Convention date, May 16. [Classes 83 (ii) and 83 (iv)] Coiling helical tubes ; corrugating ; producing flow of metal by rotary smooth discs.- In making flexible tubing by helically coiling strip around a mandrel, power-driven rolls interlock the strip edges and feed and finish the tube, and are mounted for axial, radial, circumferential and longitudinal adjustment to suit the strip and tube dimensions. Flat strip, Fig. 2 (not shown), is drawn from a coil and longitudinally corrugated between four pairs of driven rolls synchronized with the coiling mechanism by a variable gear-box. The strip passes through a guide to head 12 and is coiled about a smooth, driven mandrel 98 and three rolls 102. The mandrel 98 is chain driven through a variable gear-box 54 and is axially movable against a spring 182 for starting. The rolls 102, 104, Fig. 6, are profiled to engage the corrugations and complete the interlocking of the tube 40 and are mounted in yoke bearings 132, longitudinally slidable in housings 128 axially adjustable on screwed shafts 124 to control the helix angle. The shafts 124 are radially screw adjustable in sleeves 123 of brackets 110, mounted on a plate 114 circumferentially adjustable about the tube axis. The rolls 102, 104, &c. are - gear and chain driven through a variable gear-box 62 by splined shafts 158 with double universal couplings 162. Three profiled rollers, 206, 208, Fig. 14, engage the interlocked tube and positively feed it, and are driven slowly to planish and size the tube by rubbing. A similar head 14 allows roll-adjustment and a gear, chain and universal coupling drive is provided. The finished tube 40 is guided into a hollow drum 16 also synchronously driven through a gear-box 32 from the common motor 18 and hand or foot-operated clutch 24. To start the operation an auxiliary mandrel 216 having a slot 222 to engage the strip end is abutted against the sprung mandrel 98 between the rolls 102, 104. The apparatus is started and. the rolls and auxiliary mandrel 216 draw the strip into the first turn as the spring 182 feeds the mandrel 98 into running position. As the tube is formed and fed towards head 14 the auxiliary mandrel 216 runs out axially and is withdrawn. A collar is provided about the mandrel 98, Fig. 12 (not shown), and strips the tube off as the mandrel is withdrawn. In a modification, Fig. 15 (not shown), the mandrel 98 has a necked extension to engage between the finishing rolls 206, 208, to assist in controlling the inside dimensions.

Title: Improvements relating to the production of foundry moulds
IPC: B22D13/10
Filed: 1945-12-03
Abstract: 606,534. Moulding-machines. JONES & ATTWOOD, Ltd., and FOLKES, H. L. Dec. 3, 1945, No. 32585. [Class 83 (i)] A foundry mould for use in the casting of pipes or other substantially cylindrical articles is made by filling a box with sand, pushing through the sand a plunger shaped to correspond with the contour of the required casting and then relatively rotating the box and plunger and also relatively displacing their axes. An elongated box 1 adapted to be filled with sand is provided with peripheral tracks 25 by which it is supported on rollers such as 27. The end closures of the box have apertures through which may be pushed a plunger mounted on a carriage 10 traversable by a screw-and-nut mechanism or hydraulically. The plunger comprises a mandrel 15 having a nose 5 behind which is fixedly or rotatably mounted a pattern 6 corresponding to the form of casting required, as shown, a pipe with a spigot at one end and a socket at the other. Bearings 16 which are vertically slidable between guides 17 on the carriage 10 support the Pear end of the mandrel and after it has been pushed right through the box 1, the forward end of the nose 5 is supported in a similar slidable bearing 35 in a guide 31. In this position, the pattern may be vertically reciprocated by means of cams 39 on a shaft 32, acting on follower rolls 20 on screws 19 and 37 extending upwardly from the bearings 16 and 35 respectively. At the same time the box 1 may be rotated through its supporting rollers. The sand in the box 1 is thus compressed and an axial opening is formed of similar contour to that of the pattern 6, but of greater diameter. If the pattern is fixed to the mandrel it may be rotated by means of an arm projecting from the mandrel and engaged by a finger on the box 1. Alternatively the pattern may be rotatably mounted on the mandrel so that it is rotated by contact with the sand. In a modified form, Fig. 9, the box 1 is stationary and the pattern is rotated in an orbital path of gradually increasing diameter. The bearings 54 for the mandrel and 11 for the nose 5, are mounted on housings 53, 50 respectively, which are rotated by gears 60 on a common driving shaft 61. During the rotation, the bearings 11 and 54 are moved relatively to the axis of rotation by means of screws 51 and 55 operated by strikers 57 and 59 fixed to the bed 14. Moulds; coating and lining moulds.-The mandrel may be bored to' supply blacking to the inside of the mould and also to supply a combustible gas which on ignition serves to dry the mould, while the plunger is being withdrawn.

Title: Bulldozer blade support
IPC: E02F3/76
Filed: 1960-09-23
Abstract: 884,040. Earth-moving equipment. CATERPILLAR TRACTOR CO. Sept. 23, 1960 [Oct. 23, 1959], No. 32725/60. Class 68(1). On a dozer blade support frame are five sets of pivotal connections 17, 25, 26 of which the connections 17 allow of the blade being mounted at both ends directly on the frame parallel to the frame or at one end only so as to be at an angle to the frame. In the latter case the other end of the blade is rigidly supported from the frame by a brace 22 extending from said end of the frame to the nearest of the connections 25. The distance between the connection 26 and the connections 25 is equal to that between the apertures in the brace 22 so that when the brace is not required it can be secured between the connection 26 and one or the other of the connections. Thus the blade and the brace need never be completely removed from the frame as they are moved relative to the frame to allow as required of angling the blade thereto or positioning the blade parallel to the frame.

Title: Improvements in or relating to the regeneration of catalysts
Inventor: HODGINS THEODORE S
IPC: B01J23/94
Filed: 1956-10-29
Abstract: An iron oxide/molybdenum oxide catalyst, used in a process for oxidizing alcohols, is regenerated by treatment with a non-oxidizing compound of molybdenum in solution, drying and heating in an air stream.  The catalyst may be regenerated in situ by adding a solution of ammonia or an amine, e.g. methylamine, which dissolves the free MoO3 and redistributes it over the catalyst body which may be supported e.g. on silicon carbide. Alternatively a solution of MoCl2 in alcohol may be used. After soaking for an hour with the warm solution, the catalyst is then treated with warm air and finally heated to 495 DEG  F.  The catalyst may also be removed and sieved to segregate the major part which passes a mesh of 4 per sq. inch, but is retained by 20 mesh.  The fines passing 20 mesh, which contain the major part of free MoO3, are extracted with ammonia or an amine, and used to treat the segregated catalyst.  Specifications 814,073 and 814,074 are referred to.

Abstract: 961,492. Linear-dimension gauges; beta-ray backscattering. SOLVAY & CIE. Aug. 28, 1962 [Aug. 30, 1961], No. 33068/62. Headings G1A and G1M. The thickness of a halogen-containing polymer or copolymer coating deposited on a film of material, such as regenerated cellulose or polyethylene, having a mean atomic number different from that of the coating, is determined by measuring the intensity of back-scattered #-radiation incident on the film and coating and coming from a source of pure #-radiation such as carbon-14 or nickel-63. The supporting film must have a thickness greater than the saturation length (so that its contribution to the back-scattered radiation is constant). The Geiger-Mueller measuring tube 2 may be calibrated by taking readings using coatings of different known thickness and the virgin film. The film is supported beneath the tube 2 on a perforated disc 10 and held by suction, applied from below, via tube 11. An arm 8 supports the tube 2 above the sample. The radio-active material is,in the case of carbon- 14 placed in a groove 3, a modified construction ' being used for nickel-63, which has weaker radiation, so that the distances between the source, the film and the window of the G.-M. tube can be reduced considerably.

Title: Improvements relating to optical polarizing devices
IPC: F21S8/10
Filed: 1938-11-17
Abstract: 521,378. Optical polarizers. LAND, E. H. Nov. 17, 1938, No. 33449. Convention date, Nov. 20, 1937, [Class 97 (i)] In a polarizing device of the kind in which the polarizing medium divides a beam of non- diffused incident light into two differentlypolarized components, one of which is diffused and the other transmitted without diffusion, a lens is associated with the polarizer to form an image of the source of light the area of which is a small fraction of the cross-sectional area of the beam and a bi-refringent element is placed in the image plane, either in the area occupied by the image or in the area not so occupied, said element being such as to produce the retardation required to bring the diffused and non-diffused components to the same state of polarization. Preferably, instead of using a single lens, the area of the beam is covered by a number of co-planar lenses, and a bi-refringent element is associated with each lens. The Fig. shows a polarizer forming a closure for the front of an automobile head-lamp 11. The parallel rays from the lamp reflector are incident on a polarizing sheet 30, which is of the above-mentioned kind and may comprise a set suspension of birefringent crystals in a transparent isotropic matrix the refractive Index of which is equal to one of the refractive indices of the crystals, so that one of the polarized components passes directly through the sheet and the other is diffused by multiple internal reflections. Adjacent the sheet 30 is a glass &c. sheet 32 having its surface formed as a number of spherical or cylindrical lenses 36, and behind the sheet 32 in the focal plane of the lenses is a sheet 38 provided ;at the foci of the lenses with areas 40 of bi-refringent material of such thickness as to produce a half-wave retardation of the focused rays. The areas 42 traversed by the diffused polarized component, which is not focused by the lenses 36, is isotropic, so that on emerging from the sheet 38 the two components have the same state of polarization. A sheet 34, similar to the sheet 32 and having similar lens elements 36, may be provided to collimate the non-diffused component. A quarter-wave plate may be associated with the sheet 30 to produce two circulary-polarized components. A polarizing sheet may be provided adjacent the lens surfaces of the sheet 34 and so oriented as to block the small part of the diffused component which has traversed the areas 40 and therefore has characteristics different from those of the rest of the beam. Both the areas 40 and the areas 42 may comprise bi-refringent material, provided the difference between their retardations is such as to produce the desired result. In a modification, the sheet 30 is arranged between the lenses and their focal plane.

Abstract: 605,012. Printing processes. GOSS PRINTING PRESS CO., Ltd. Dec. 11, 1945, No.- 33550. Convention date, Dec. 11, 1944. [Class 100(ii)] In a method of printing electrically such as is set out in Specification 604,012 in which the ink passes from a member bearing type or a design to a web, which does not touch the member, under the action of an electrical field, the web is charged electrically to a desired potential relative to the said member prior to passing to the design member and the electric field may be obtained solely by the charge on the web. As shown in Fig. 1 the web is first passed between static electricity eliminators 13, 14 of known kind which are earthed, and then the web is charged to the desired high potential by passage between rollers 15, 16 formed of conducting rubber connected to a source C of high potential comprising a terminal charged to a high potential relatively to an earthed terminal, the high potential terminal being connected preferably to both rollers 15, 16 so as to charge both sides of the web. The circuit includes alternating current mains 17, 18, a step-up transformer, and a rectifier. The static eliminator, is formed of metal mountings 13a, 13b, Fig. 4, between which extend an outer insulating tube of glass 13c, and an inner metal tube 13d in which are mounted carriers for needle point members 13e which rotate close to but out of contact with the web. The charged web passes close to the printing-roller 10 and is guided by a wedge-shaped block 22 of highly polished glass which defines one edge of the printing zone. For applying a second colour the web is passed over guide rollers 23, 24, and preferably the print is dried by a flame drier 25, after which the web is treated by static eliminators 33, 34, and one side of the web is charged to a high potential by a roller 35 similar to the rollers 15, 16. In addition to the wedge 42 near the printing-roller 30 a guide block 43 is used, and if a drier 25 is not used the wedge 42 is arranged so as not to touch the once printed surface. In a modification Fig.. 3, for multi-colour printing three units D, E, F are employed which are similar in construction to those described in Specification 604,012. Before the web enters each printing zone it is passed over guide rollers 58, or 58<1>, or 58", which may be arranged to charge the web to a high potential, or may be plain rollers which do not affect the web if charged with static electricity. The web then passes between members 56, 57 similar to the static eliminators, but the members instead of being earthed may be connected to some means at a predetermined potential with respect to the earth such as to a voltage divider energised by a high voltage supply unit such as is described above. The parts 56, 57, 58 may be reversed in which case the members 56, 57 are earthed and serve to eliminate static electricity, and the rollers 58 charge the web to a desired potential. Driers 59. 59<1> are arranged between the units D, E and E, F. U.S.A. Specifications 1,820,194 and 2,224,391 are referred to.
