Title: An improved machine and method for forming packing and packing produced thereby
IPC: F16J15/26
Filed: 1926-05-27
Abstract: 273,070. White, A. E., (Crane Packing Co.). May 27, 1926. Packing, metallic; packing, compound metallic and non-metallic.- In a machine for making packing for condenser tubes &c., strips of lead or other metal foil, with or without paper or other fabric containing lubricant, are drawn from rolls 30 by feed rollers 23 and are corrugated longitudinally by rollers 34, 35, being at the same time wound on to the roller 34. When a ring has been wound the packing length is cut off by a. knife carried bv an arm 40, and the ring is pressed by a stripper 52 into a die 69, which is then moved in guides 72 to a punch 80. The punch compresses the packing and thus corrugates it axially, and the ring, after being lifted by an ejector 84, is discharged into a shoot by a reciprocating bar 95. The main shaft 10 of the machine drives a vertical shaft 12 through bevel gearing 11 and, through chain gearing, drives a cam shaft 63, and a shaft 67, which operates the punch 80 by means of a connecting-rod 83. The shaft 12 drives the feed rollers 23 through a gear train 13, 14, 16, 21. One of the rollers 23 is carried by an arm 24 on a spindle 25, an arm 26 on which engages a cam 28 on the shaft 12, which lifts the roller and thus interrupts the feed when the ring has been wound. The roller 34 is mounted on a shaft 47 driven through a gear train 48, 49, 51 from the wheel 13 on the shaft 12; while the rollers 35 are carried by a spring-controlled lever 37. The knife-arm 40 Figs. 1 and 7, is mounted or. a spindle 41, an arm 42 on which engages a cam 44 on the shaft 12, and is adjustable by means of a screw 46 in order to vary the timing of the cutting operation. The stripper 52 is engaged by the forked end 54 of a bell-crank lever, operated by a link from a cam on the shaft 63. The die 69, Figs. 1 and 11 is moved in the guide 72 by a link 73 from a bell-crank 74 operated by a cam on the shaft 63. The die has a core 71 and the ejector consists of a sleeve 70 connected by rods 84 to a plate sliding in the head 86 of a rod 87, which is lifted by a cam on the shaft 63 through a lever 89. The bar 95 is reciprocated by an arm on an oscillating spindle, another arm on which is connected by a link to a lever operated by a cam on the shaft 10.

A rectilinear guide bar or toothed rack 8 of trapezoidal cross-section, is secured in a similarly shaped groove 10 in a machine tool 9 by inwardly deforming the edges 13 and 14 of the groove. The deformation can be applied by a roll 20, Fig. 8, having shoulders 21 and 22 which straddle the bar or rack. A further roller 24 precedes the roll 20 and serves to apply the bar or rack against the groove bottom. The roll 20 is freely rotatable on the shaft 19 of a tool carrier 18, whilst the roller 24 is pivotally mounted on the carrier and urged against the work by adjustable spring pressure. The roll 20 may be in several parts, to enable the spacing of the shoulders to be varied. Several rolls or rollers may be provided in tandem and each roller 24 may be carried independently of the carrier 18.

Abstract: 809,839. Capacitors. BRITISH DIELECTRIC RESEARCH Ltd. May 2, 1957 [May 3, 1956], No. 13747/56. Class 37. A first electrode in the form of a wire or rod is separated from a self-healing electrode by an anodically-formed dielectric layer of a filmforming metal and connection is made to the self-healing electrode by a lead which is anchored at one end by an intervening mass of a thermosetting resin. The self-healing electrode extends over this mass and on to the connecting lead. The opposite end of the first electrode forms or is attached to the other connecting lead. As described, a wire 1 of aluminium or tantalum is cleaned chemically or by electropolishing before being anodized to form a dielectric layer 2. The second lead 4 of copper or other metal is cemented to the anodized end of the first by a thermosetting resin, preferably an epoxide resin. The anodizing process may be repeated before the self-healing electrode 3 is deposited by vacuum evaporation over the dielectric 2 and the resin bead 5 to make contact with the second lead 4. The wire 1 may alternatively be of copper or other metal coated with a film-forming metal. Where the diameter of the wire 1 exceeds 1 mm smaller diameter connecting leads may be used, one of which is welded to the wire 1. Capacitance values for various forming voltages are given.

Abstract: 1,075,605. Moulding cylinders of foam plastics. REEVES BROTHERS Inc. April 5, 1965 [April 7, 1964], No. 14299/65. Heading B5A. A method of forming a cylinder of polyurethane foam comprises pouring foamable liquid into a mould which has a flat bottom at the pouring point but gradually changes to a generally cylindrical form. As shown, paper (13) unwound from a roll (12) is drawn through a mould-shaping element (14) which has a cylindrical part (14A), and a part (14B) formed by splitting the cylinder along its uppermost line. As the paper is drawn therethrough it gradually assumes cylindrical shape. A downwardly-inclined flat strip (16) is fixed in the part (14B) and extends into the cylinder (14A), the width of the strip gradually decreasing from initially being equal to the diameter of the cylinder to be formed. Paper or plastics, e.g. kraft paper or polyethylene led over the flat strip from a roll (18) is drawn through the forming element at the same rate as the paper (13) and gradually assumes a U- shape to provide a holding channel for the foamable liquid. In operation, the foamable liquid is poured into the mould at the start of the flat strip and is drawn along while it foams. The foaming mixture reaches the end of the flat strip before foaming ceases, preferably in less than ¥ of the foaming time period. The mould is now cylindrical and the mixture continues to foam and thereby assume cylindrical shape. The flat strip may have an initial portion of small decline, the remainder being of greater decline, and the element (14) may be slightly upwardly inclined.
