Abstract: 999,206. Attaching heels. BRITISH UNITED SHOE MACHINERY CO. Ltd. Oct. 17, 1961 [Oct. 19, 1960], No. 37108/61. Heading A3B. A heel attaching machine comprises a presser head 40 and heel abutments 112, 120 provided on racks 86, 88 slidably mounted in guideways 82, 84 in a pair of guide members 78, 80 which are pivotally mounted on a carrier 64, and means, in the form of two adjusting rods 106, 108 for initially moving the guide members into different angular positions about the pivot 74 upon which they are mounted. The racks 86, 88 mesh with a pinion 76 mounted for rotation about the pivot 74 on the carrier 64. The presser head 40 is interchangeably secured by means of an adaptor which fits into the carrier 64 to a fluid operated piston rod 42.

Title: Improvements in or relating to the manufacture of metal-forming tools, especially hammer-forms, drop-hammers and stretch-forming dies
Inventor: MATTHEWS STANLEY
IPC: C08L63/00
Filed: 1955-12-28
Abstract: A metal forming tool, such as a drop hammer punch or die or a stretch-forming die, has at least its working face composed of a hard resilient synthetic resin obtained by reacting an epoxide resin with a polyamide resin.  Preferably the tool consists of a core portion and a facing of the resin although the entire tool may be made of the resin.  A filler of up to 15% by weight of asbestos fibre and/or chopped glass fibre may be used with the resin.  The epoxide resin may be an ethylene oxide derivative of phenols and the polyamide resin may be obtained from amides of polybasic resins; the latter may comprise from 15 to 65% by weight.  Examples of proprietary resins and typical compositions are given.  The core may be of wood, resin-impregnated wood, concrete, cast iron, mild steel, or a filler of wood chips, shavings or wood flour bonded with the thermosetting synthetic resin.  In the latter case the mixture is used to partially fill a plaster mould and after curing the core formed thereby is removed from the mould, dressed and again inserted in the mould leaving a clearance which is then filled with the epoxide/polyamide resin. Two different mixtures of the latter giving different hardnesses may be used to face a single tool.ALSO:A metal forming tool, such as a drop hammer punch or die or a stretch-forming die, has at least its working face composed of a hard resilient synthetic resin obtained by reacting an epoxide resin with a polyamide resin.

Title: Improved means for facilitating the starting of internal combustion engines
IPC: F01L13/08
Filed: 1930-12-09
Abstract: 368,762. Starting. LEYLAND MOTORS, Ltd. and BIGGAR, P. E., Motor Works, Hough Lane, Leyland, Lancashire. Dec. 9, 1930, No. 37164. [Class 7 (v).] To facilitate the starting of a compressionignition engine the cam shaft A is driven through helical or like gearing E, F and is movable longitudinally by hand or by the operation of starting mechanism to advance the closing of the inlet valve towards the beginning of the compression stroke, so that compression extends over a greater portion of the stroke and a higher pressure and temperature are obtained. As shown, the shaft A is moved axially by means of a lever B. On moving the lever B to the right in the Figure, a collar C engages the valve tappet D and holds the inlet or other valve open and the engine can then be swung over. On moving the lever to the left, the cam G comes under the tappet and the turning movement caused by the helical gearing causes the inlet valve to be opened and closed earlier than in normal running. In a multicylinder engine, compression may be relieved in all but one or two cylinders, and simultaneously increased in the remaining cylinders to assist ignition. The lever B may be, or may be connected with, the lever which sets a selfstarter in action, or the shift of the cam shaft may result automatically from the starting action. The shaft A may be returned by a spring &c. when the engine overruns the starter, or when the starter is put out of action, or may be returned gradually by screw-and-nut means.

Abstract: 835,410. Nuclear fuel elements. ENGLISH ELECTRIC CO. Ltd. Dec. 7, 1956 [Dec. 29, 1955], No. 37345/55. Drawings to Specification. Class 39(4). In a nuclear reactor, the temperature of fuel element is measured by a thermocouple. The elements are located by spacers inside channels in the graphite pile. The spacers make electrical contact, by means of spring loaded contact points, with contact areas on the channel surfaces ; the points and the surfaces forming part of the thermocouple circuit with an external indicator. The contact areas are formed of wire gauze bedded in fused magnesia set into graphite. Differential thermal expansion between the fuel element and the pile produces longitudinal sliding between the points and areas, in addition, the areas subtend slightly more than 120 degrees so that whatever the angular position of the fuel element relative to the fuel element channel at least one spacer contact point touches the contact area.

As shown, Fig. 4, a programme for a numerically-controlled machine tool is prepared in dependence on a family of cutter sizes ranging from T-O1 standard size to T-O5 which is 40 thousandth of an inch undersize due to successive re-grinding. The programme is prepared in segments, 34, 33 each of which represents a machining operation for which a tool has to be selected, and comprises separate machining instructions for an operation for each cutter of a family. A machine tool, not shown, is actuated by signals from a control 21, Fig. 5, responsive to a tape reader 24 which is stepped by signals from a control 75. The selection of a cutter size for an operation is made by an operator actuating a switch bank 30 which sets a store 45, having indicator lights 29s, and a register 55. The contents of store 45 are compared in a device 65 with the contents of a store 85, having indicator lights 29p, which is responsive to signals from the controller 21 as the control 75 stops the tape in the reader 24. The reader control 75 is stopped when coincidence is established. The controller 21 carries out the machining operation at the completion of which the selected tool store is cleared and the start of a subsequent operation inhibited until a new tool selection is made. The register 55 clamps reader control 75 until a tool selection has been made to prevent synchronous operation of the reader, a switch 31 is closed to by-pass the register when using an uncoded tape. The movement of the tape is initiated by actuating a scan-switch 32 after the selection of a toolcode on switch-bank 30. The circuit is arranged to ignore codes in a completed operation by recognition of the T-01 code of the new operation.

A sub-aqueous well is drilled by lowering a drill string 21 having a bit 25 from a platform 11 at the surface until the bit contacts the formation to be drilled, drilling a hole 31 in the formation with the bit, lowering a rod 35 through the string and through an axial opening 26 in the bit, and removing the string and bit from the hole to the platform, the lower end of the rod remaining in the hole. During drilling of the hole a core bit and barrel 27, 28 is latched in the bit 25, the core bit and barrel being removed by a fishing tool 32 when the hole is complete. The rod which is of a length slightly greater than the depth of the water at the hole is lowered through the string, and the string is raised, the upper end of the rod being prevented from passing through the bit by a bar 36. The string is removed from the rod at the platform whilst the rod extends from within the hole to the platform. A conduct pipe 41 is lowered over the rod into the hole by a running tool 45, and the pipe is cemented into the hole after the rod has been removed. In use of the apparatus shown in Figs. 7 and 8, a rod 35a is dropped through the string 21a after the core bit and barrel 27a, 28a have been removed. The string is raised about the rod a reamer bit 50 being added to the string before the bit 25a passes the upper part of the rod, and the string is rebuilt, lowered, and rotated to enlarge the top of the hole 31a after the rod is removed. When the hole has been sufficiently enlarged to receive a conductor pipe, a longer rod is dropped through the string to extend to the surface, the string including the bits is removed, the conductor pipe is slid down the rod, and the pipe is cemented after the rod is removed.
