Title: Improvements in or relating to the production of matched embossing rolls
IPC: B41C1/18
Filed: 1957-12-11
Abstract: 814,565. Making embossing rolls. MODERN ENGRAVING & MACHINE CO. Dec. 11, 1957 [June 27,1957], No. 38559/57. Class 83 (2). A method of producing hardened metallic matched embossing rolls comprises hardening a pair of steel rolls 6 and 8 and applying an acidresistant coating thereto, rolling a co-extensive master pattern roller 18 on a first one of the rolls to remove the coating from predetermined areas thereof, etching the said first roll to remove metal from said areas, removing the remainder of the coating, rolling the now embossed roll on the second roll to remove its coating from complementary predetermined areas and then etching the second roll. The master roller 18 is made by a series of steps. The pattern of a die roll 10 is first rolled into a comparatively soft roll 14 which is then hardened and used to engrave the pattern on the roller 18, the roll 14 being fed axially across the roller 18 for this purpose. The rolls 6 and 8 are etched by dipping in a suitable etching fluid, such as nitric acid and the remaining coating and the acid are removed by a rinsing operation. The coating and etching steps may be repeated as often as necessary to produce the required depth of pattern. When the rolls 6 and 8 are to be used to emboss heavy gauge material, a clearance between the pattern projections of the rolls may be desirable and may be accomplished by making the first roll of slightly larger diameter and etching it to a greater depth after it has transferred the pattern to the second roll.

Title: Methods and apparatus for making concrete pile shells and piles
Inventor: UPSON MAXWELL MAYHEW
IPC: E02D5/50
Filed: 1959-11-16
Abstract: 870,497. Piles. RAYMOND INTERNATIONAL Inc. Nov. 16, 1959, No. 38690/59. Class 68(2). A method of constructing a hollow concrete pile shell comprises seating a casing 23 on a driving shoe 22, driving it partly into the ground and then positioning therein a hollow mandrel 25 which has centring lugs 26. A hopper 28 is fastened to the top of the casing and concrete is fed into the annulus 27. The complete unit is then driven to its final depth and the casing 23 pulled up. The initial heavy pull may be applied by an apparatus as shown in Fig. 2a or 2b so that a corresponding reactive force will act on the shoe 22 via the mandrel 25. Fig. 2a shows a mast 200 which has a T-head 201 from which are suspended pulley blocks 206 and 207. The cables 204 and 205 are taken to winding drums (not shown). The reaction of the upward force applied to the casing is transferred to the mandrel 25 by a shoulder 203 on the mast. Fig. 2b shows an hydraulic piston 211 and cylinder 212 wherein the piston is attached to a crosshead 214 which is secured by links to the casing, and the cylinder 212 is positioned within the mandrel 25 and has a shoulder 215 which bears on the top of the mandrel. In order to cause the concrete to fill the void left as the casing is withdrawn a vibrator may be provided inside the mandrel, or vibrators may be attached to the casing and drawn up through the concrete with the casing. Setting of the concrete may be hastened by heating the interior of the mandrel by steam, and a water pipe may be provided to subsequently cool the mandrel and assist extraction. In a modification a thin metal liner 40 (not shown, see Fig. 6) is positioned either immediately inside or outside the casing and remains in the ground when the casing is withdrawn. In a second modification a thin corrugated metal liner 87 (Fig. 14), which makes a watertight joint with the driving shoe, is positioned so as to closely surround the mandrel, and remains inside the pile shell when the mandrel is withdrawn. In a third modification the method is used to construct a composite pile comprising lower metal sections 82 and 83 (Fig. 14) and an upper part 81 constructed as described above. In this case the driving shoe is replaced by a driving ring 86 and a conventional taper mandrel 84 is used. So that this mandrel may be withdrawn before the concrete has set, the thin liner 87 is supported against ground pressures until the concrete sets by an auxiliary stiffener shell 91 which is subsequently withdrawn. In a fourth modification a composite pile is formed in which the lower section comprises a parallel tubular element 108, closed by a plate 110 and attached to a driving shoe 107. The assembly is stiffened during driving by a mandrel 103 which partly enters the lower section. When the mandrel has been removed the pile is completed by filling the upper and lower sections with concrete.

Abstract: 869,275. Cables. ENGLISH ELECTRIC CO. Ltd. Dec. 11, 1957 [Dec. 19, 1956], No. 38780/56. Class 36. A multi-conductor connecting device in the form of a flexible cable strip for linking two relatively displaceable bodies, comprises a plurality of insulating conductors 10 embedded within a flat rubber or rubber-like strip 11 together with spring wires 12 to provide a positive coiling or uncoiling tendency therein. The cable strip may be formed into a vertically disposed coil (Fig. 4), the ends being attached to frame members 13 and 14 subject to relative angular displacement, the lower side edge of the strip being supported on a bracket 30. To reduce friction the strip may be provided with a coating of nylon or polytetrafluoroethylene at least around the lower side edge; alternatively a series of rollers may be provided along this edge. The spring action at the lower side edge may be accentuated by suitably distributing the spring wires. When the cable strip connects members having relative longitudinal movement it may be formed into a simple bight and when it connects two members coaxially spaced apart and subjected to relative angular displacement it may be wound into a helix (Fig. 9, not shown). The strip may be made by laying the conductors and spring wires on a rubber mat and moulding rubber around and over them so that the mat and moulded rubber form a common covering.

Abstract: Synthetic garnets of formula M3Me5O12, where M is at least one rare earth metal (atomic No. 58-71, and Y) and Me is at least one trivalent metal, preferably Fe, Al or Ga, are crystallized from a melt of the constituent oxides in a flux of PbF2 and B2O3.  The flux may also contain PbO, such that the PbO:PbF2 ratio is 0-1.5:1 and the B2O3:(PbO + PbF2) ratio is 1:20-200 by weight. The constituent oxide:flux ratio may be 1:12.5-2, or 2-3 times as concentrated if seed crystals are added. The Me oxide starting materials may be present in excess of stoichiometric, up to 100% for Fe and Ga, and up to 500% for Al.  Minor amounts, e.g. 0.01% of other rare earth or transition metal ions may be incorporated by adding an excess of up to 100% in the flux. The crystals are obtained by cooling the melt from 1300 DEG  C. to 950 DEG  C. at rates of from 1/2 -10 DEG  C/hr. then air-cooled to room temperature, and the flux residue dissolved in boiling 50% HNO3.  In the examples Y3Fe5O12, Y3Al5O12 containing Nd, Y3Ga5O12 containing Nd, and Er3Al5O12 containing Tm, are prepared.  Also referred to are (Y + Gd)3Fe5O12 and (Y + Er)3 Al5O12 containing Tm.
