IPC: B29C48/10
Filed: 1971-03-13
Abstract: 1372726 Films GENERAL ENG CO (RADCLIFFE) Ltd 10 March 1972 [13 March 1971] 6824/71 Heading B5B  An apparatus for oscillating and re-orienting extruded plastics material tube or film 103 includes take-off rollers 100, 101 adapted to be oscillated about the longitudinal axis of the tube or film approaching the take-off roller to create a helical twist in the tube, and film re-orienting means oscillatable with and at the same angular rate as the take off rollers, including at least two turner bars 105, 107 he axes of which are disposed angularly relative to the axes of the take off rollers, whereby, in ue, film passing therethrough is re-oriented, and at least two guide elements 108 disposed with their axes parallel to and minimally offset from the axis of oscillation of the take-off rollers, between which re-oriented film is, in use, passed for delivery to a non- oscillatory reeling or winding mechanism. As shown, a guide roller 106 may be located between the two turner bars, which are suitably disposed so that the first turner bar 105 has its longitudinal axis in a plane substantially at right angles to the axis of oscillation of the take off rollers, and the second 107 having its longitudinal axis in a plane parallel to the axis of oscillation of the take off rollers. In use, the first turner bar preferably turns the film to reverse its direction of movement and simultaneously displace its direction of movement by approximately 45 degrees in the plane of the film. Preferably the turner bars have a rounded surface, and are hollow and apertured at spaced intervals so that they may be supplied with air or other gas so as to provide a gaseous cushion at the surface over which the tube or film slides during re-orientation. The guide roller and turner bar system is suitably mounted upon an oscillatable table; in this way the system can be rotated through substantially a complete revolution in one direction and then reversed. Alternatively, the guide elements can be non-oscillatory.

Abstract: 1,102,631. Winding metal strip. SOCIETE DE CONSTRUCTIONS MECANIQUES DE CREIL C.O.M.E.C. 18 Feb., 1966 [16 Feb., 1965], No. 6842/66. Heading B3E. [Also in Division B6] Apparatus for winding a plurality of juxtaposed metal strips on the same arbour comprises separate clip means for holding the end of each strip and friction discs interposed between adjacent clip means and keyed on the arbour to entrain the clip means, and thus the strip coils forming thereon, in rotation with the arbour with a torque proportional to the axial pressure of the discs on the clip means. Strips a, b, c longitudinally slit from a web are secured at their ends to clips 10 supported on bearers 12 keyed to a rotated winding spindle 11. Friction discs 14 between adjacent clips 10 are also keyed to the spindle 11, the assembly of discs 14, clips 10 and bearers 12 being subjected to axial pressure by an hydraulically urged clamping cap 16. In operation any variation in tension between the strips being wound is taken up by the slipping of the appropriate clips 10 relative to their adjacent friction discs 14. After winding the cap 16 is removed and the assembly of coiled strip, clips and bearers is pushed off on to the arms of an unloader E which rotates about a vertical axis to present the assembly to a rockable unloading member F which feeds one section of coil, bearer and clip at a time on to a roller conveyer G. At a station H the coil is separated from the clip and bearer which are returned by conveyers I, J to the winding station. When winding aluminium strip, the clips may be in the form of cardboard sleeves to which the strips are secured by adhesive tape, recovery of the sleeves being, in this case, unnecessary.

Title: Improvements in and relating to percussion tools
IPC: B25D17/08
Filed: 1956-03-07
Abstract: 827,732. Percussive tools. LEAVELL, C. March 7, 1956. No. 7230/56. Class 124. A pneumatic paving breaker has means for selectively producing a pneumatic force between the casing and the steel of sufficient amount to move the casing relative to the steel in a direction away. from the work and is provided with an impact pin, which in an extended position engages the steel and arrests vibratory movement of the casing away from the work and converts such movements into impact forces acting on the steel to move it away from the work and in a retracted position is inoperative. As shown, a casing 10 has a cylinder 18 with. a piston 20 which strikes an anvil 23 to produce a blow on a steel 28. The anvil is slidable in a chamber 22 and has a large diameter portion 25 joined to a smaller diameter portion 24 by a shoulder 26. The front end of the casing has a steel retainer 31 and a pin 39 normally held retracted in a bore 38 by a spring 42 but which may be extended to engage a flange 29 on the steel on the side nearest the work by pressure air admitted to a bore 36 in the casing by a manually operated valve 40. A bore 37 leading from the bore 36 to the anvil chamber admits pressure air to operate on the shoulder 26 and raise the casing relative to the anvil and the steel. The spring 42 is so adjusted that the casing is raised before the pin 39 is extended to engage the flange. The movement of the piston then produces vibrations which are converted to impacts of the pin on the flange and the steel is driven out of the work in which it may have become jammed. The amount of pressure air, and so the rate of raising the casing and extending the pin, may be controlled by a screw 59 penetrating the bore 36.

Title: Improvements in and relating to moulds for use in pressing, die-casting and injection moulding operations
IPC: B29C33/56
Filed: 1941-06-10
Abstract: 550,563. Moulds for injection-moulding, die-casting etc.; electrolysis. FRANKENTHAL, A. O., LONDON & SCANDINAVIAN METALLURGICAL CO., Ltd., and KOHNSTAMM, E. June 10, 1941, No. 7346. [Class 87 (ii)] [Also in Groups XXII and XXXVI] The mould comprises an electrodeposited shell which constitutes the working face, and a backing of high melting point metal of which the metal next to the shell is sprayed on the shell and the remainder is cast on the sprayed metal. The shell may be of nickel or nickel alloy, the sprayed metal may be steel and the cast metal steel or cast-iron. In one example the cast metal is applied by passing it into a cup-like frame containing the sprayed shell. The mould may be electrolytically polished, and may be finally chromium plated. In making the shell, a pattern of phenol-formaldehyde resin or cellulose acetate is prepared. (If cellulose acetate is used, the parts of the pattern may be separately machined and then built up and stuck together by softening their abutting surfaces with acetone. If the entire pattern is coated with acetone it assumes a high polish which is later found in the electrodeposited shell. If the article to be formed by the finished mould is to have holes such as can be formed by pins projecting from the mould, steel pins are inserted in the pattern.) The pattern is degreased, silver coated by applying a solution thereto, and those parts where no nickel is to be deposited are cleaned with nitric acid, to remove the silver, or covered with a lacquer. The pattern is suspended by lacquercovered copper wires and rotated in the bath. The pins which were inserted in the pattern are tightly gripped by the deposited nickel. The pattern may be removed from the shell by dissolving, melting, burning or by mechanical means. U.S.A. Specification 1,912,889 is referred to.

Title: Improvements in or relating to anti-vibration mountings
IPC: F16F15/00
Filed: 1936-03-12
Abstract: 476,671. Resilient mountings. MEREDITH, F. W., and BARNES, J. W. March 12, 1936, No. 7418. [Class 108 (iii)] In an anti-vibration spring mounting, in order to ensure that the natural frequency of the free oscillation of the supported apparatus remains substantially constant irre spective of the mass of the apparatus, the form of spring and its supports are so selected that the stiffness of the spring varies in accordance with its deflection according to the equation where S is the stiffness, f the desired frequency of oscillation, Lo the minimum load at which the desired frequency is to be maintained, and D the deflection. A combined mathematical and graphical method of obtaining a suitable spring is described in the Specification, the spring being a cantilever spring or having (1) coils of progressively increasing length co-operating with a flat support, (2) coils of varying radius and constant pitch co-operating with a shaped support, and (3) coils of equal diameter each of which sits on the one beneath it. A method of obtaining the shape of the support referred to in (2) above is also described. As shown, the mounting comprises a casing 1 secured, e.g. to an instrument or instrument panel 16 on an aircraft, and a stud 3 secured to a supporting bracket 12 the parts being separated by a conical spring 11, the stiffness of which increases with the load due to the coils successively contacting with the flat or conical end of the casing. Vertical movement of the casing relatively to the stud is limited by flanges 6, 7 on a rubber sleeve 5 carried by the stud engaging a plate 8 which is secured to the casing by the screws which fix the casing to the supported structure. A hole 13 through the sleeve and stud is adapted to receive a tommybar by means of which the stud may be prevented from turning while the nut 4 is being tightened. For supporting heavy loads, the plate 8 may be secured to the casing in reversed position to increase the initial compression of the spring. The spring may be of waisted form.
