The upper carrier sheet 5 is turned over through 180 degrees by a reversing mechanism comprising a frame 12 and rollers 13, 14 so that its coated surface faces downwards towards the coated surface of the lower carrier sheet 6. Each carrier sheet may be printed using triple equipment 9 with associated heaters 9A for printing in three colours and after printing and coating the sheets may be passed below heaters 11. Reinforcement material, e.g. glass fibre or chopped wire matting, may be applied to each carrier sheet from rollers 15, 16. Heating means 19 may be provided to accelerate curing. An uncoated strip may be left at each edge of each carrier sheet for folding over the edges of the composite sheet to form a removable packaging therefor. Gel-coat resins which may be clear or colour pigmented may be used and may be applied by the action of blades at suitable spacings. Duplicate applicators may be provided so that one set can undergo cleaning while the other is in use.

Title: Method of and Means for Applying a Sonic or Ultrasonic Transducer System to a Surface to Prevent Deposition of Materials Thereon

IPC: B08B17/02
Filed: 1966-10-13
Abstract: 1,190,917. Sonic couplings. ULTRASONICS Ltd. 10 Oct., 1967 [13 Oct., 1966], No.45752/66. Heading H4J. A substantially rigid coupling member is secured to the side of a probe of a transducer system and to a surface to be vibrated with sonic or ultrasonic energy sufficient to prevent deposition on the surface of materials in contact therewith, the coupling member extending at least initially in a direction substantially at right angles to the direction in which the probe vibrates. Preferably the contact area of the coupling member with the side of the probe is fairly small compared with the end surface of the probe In one embodiment (Fig. 2) a pipe 1 through which liquid may flow is welded to a coupling plate CB each end of which is welded to the probe P of a transducer device. One or more additional transducer devices each have a probe P coupled to the pipe 1 by a looped coupling bar CC (see also Fig. 3, not shown) whose ends are welded to the probe P and pipe 1 as before. The axes of the probe P and connection position of the pipe 1 are mutually perpendicular but the looped bar CC extends from the probe P at right angles to the probe P axis. In Fig. 1 (not shown) a single cylindrical probe P is coupled to a pipe (1) by a bar (CA), one end of which is curved and welded to the curved face of the probe (P) while the other end is formed with a hole through which the pipe passes, the pipe being welded thereto. The bar (CA) is only secured around approximately one quarter of the circumference of the probe (P). The pipe is of smaller diameter than the probe (P). Alternatively (Fig. 4, not shown) the pipe (2) is of larger diameter than the probe (P), the bar (CD) being welded to a portion of the probe and to a portion of the pipe circumference. Alternatively (Fig. 5, not shown) a pipe (1) passes through and is welded to a plate (CE) in the form of a four-armed spider to each arm of which is welded the probe (P) of a transducer device. For preventing crystalline deposits on the wall of a container 3 (Fig. 6) suspended in fluid M, the probe P of a transducer device is coupled to the bottom edge of the container 3 by a coupling ring CF welded to the circumference of the probe P. Alternatively, the coupling ring CF couples the probe to the container wall part way up the wall. Instead of being a ring, the coupling member may be a bar spanning the container and welded at its ends to the container.

Title: Method of punching sheet metal pieces having substantially annular sector shape

Abstract: 1442372 Punching ALLMANNA SVEN ELEKTRISKA AB 4 Oct 1973 [5 Oct 1972] 46365/73 Heading B3W Two rows of blanks 6 of annular sector shape, having first and second curved edges 10, 9 corresponding respectively to the inner and outer peripheries of the annulus and two radial edges 7, 8 which subtend an angle at the centre of the annulus of between 40 and 80 degrees, are punched from metal strip, the width of which is greater than the radius of the first curved edge 10 and less than twice the radius of the second curved edge 9, by first feeding the strip through a punch press with tools shaped to the blank profile and with a cutting edge corresponding to one of the radial edges parallel to and almost coincident with one edge of the strip. Blanks are punched successively from half the width of the strip and the remaining strip width 13 is coiled and fed again through the punch press with the cutting edge referred to now parallel to, and almost coinciding with, the opposite edge of the original strip. This is done either by feeding the coil through the press again from the same side or feeding it from the discharge side after turning the punch through 180 degrees. The scrap portion 18 produced in the first punching operation is severed by a scrap cutter 19. The press includes feed rolls 17 and it is preferably a portion of the press comprising only the punch tools (3), (4) Fig. 1, not shown the rolls 17 and the cutter 19 which is turnable. Loop sag indicators (16) and (20) precede and follow the press and a brake device (21) subjects the strip portion 13 to tension, inducing in the strip tensile stress of more than 5 per cent of the stress at the elastic limit of strip of between 0À20 and 0À60 mm. thickness.

Title: Superconductive memory
IPC: G11C11/44
Filed: 1963-11-25
Abstract: 1,033,179. Superconductive circuits. RADIO CORPORATION OF AMERICA. Nov. 25, 1963 [Dec. 7, 1962], No. 46537/63. Heading H3B. A memory arrangement comprises a memory plane 30, Fig. 3, in the form of a thin sheet of superconductive material which is sandwiched between and insulated from a sensing plane 32 and a co-ordinate arrangement of X and Y drive lines, the sensing plane consisting of a conductive sheet which is coupled to an output circuit 50. The output circuit is connected to single terminals 46, 47 on opposite edges 41, 43 of the sensing plane or to parallel-connected terminals spaced along the opposite edges. In a modification. Fig. 6, the sensing plane 32 has a slot 80 adjacent one edge, and the output circuit is coupled to the plane by a secondary winding 84 on a transformer core 83 which passes through the slot. Edge excitation of the sensing plane may be prevented by providing a surrounding shield plane, Fig. 10, which is electrically joined to the memory plane. The shield plane is superconductive, and has an aperture 90 for the output circuit conductors. Tin may be used as the superconductor material and copper as the material for the sensing plane. In a modification the sensing plane is also superconductive. An arrangement is described, Fig. 7 (not shown), in which the sensing plane is a thin silver layer on a glass substrate and the superimposed memory plane and drive lines have intermediate insulating layers of silicon monoxide. The arrangement operates on the principle that coincident half-currents in an X and in a Y drive line together produce sufficient field strength at the crossing point to penetrate the superconductor memory plane. This produces circulating currents 22, 24, Fig. 2, which persist after the half-drive currents terminate, the direction of current circulation determining whether " 1 " or " 0 " is stored. Coincident half-currents in a standard direction are used for interrogation. If the memory location at the crossing point is in the " 1 " state, the location will go resistive and a magnetic field will penetrate the memory plane, thus inducing a current in the sensing plane. If the memory location is in the " 0 " state, the existing circulating current will tend to be neutralized. The memory plane will remain superconductive and the magnetic field will not penetrate.
