Title: Improvements in or relating to safety devices for pressing, stamping and like machines
IPC: F16P3/24
Filed: 1933-04-08
Abstract: 417,532. Machinery guards; locks. WELLS, A. W. J., Progress Works, Somers Road, Walthamstow, London. April 8, 1933, No. 10589. [Class 80 (iv).] Power presses and like machines having a rocking- key clutch of the type described in Specification 302,061, [Class 80 (iv)], are fitted with a device which only throws in the clutch if both handles are operated simultaneously. The bolt 14<1> carries a spring-pressed pin 26 and the bolt 14 is formed with two sockets 28, 29. If either bolt is depressed before the other, the pin slips into one or other of the sockets. The parts are so dimensioned that when this occurs one of the abutments 31 at the lower end of the bolts is close to a stop bracket 30; consequently further downward movement sufficient to free the catch 12 cannot take place. Means as described in Specification 302,061 or 417,533 may be additionally fitted to prevent the ram descending if the handles are free prematurely. The pin may be freed from a socket by means of a rod pushed through a slot 32. The rod may have the form of the key shown in Fig. 3 which is adapted to work in connection with curved slots 33.

Title: Variable electrical resistance
IPC: H01C10/18
Filed: 1924-04-30
Abstract: 233,513. British L.M. Ericsson Manufacturing Co., Ltd., Norbury, W. D., and Bates, F. April 30, 1924. Variable resistances. - Two or more separate resistances have one or more contacting arms rotating with the main control handle and adapted to be thrown into or out of engagement by one or more concentric spindles passing through the main spindle. As shown, two resistances A, B of different values are wound on strip formers and mounted in concentric grooves in an insulating base. Contact is made with the resistances A, B by the long and short arms respectively of a U-shaped spring C mounted on a hollow spindle controlled by the main knob. The longer arm of the spring C is adapted to be lifted out of contact with the resistance A by means of a concentric spindle D having a screw-thread F and operable by an auxiliary knob E. By this means either the resistances A, B in parallel or the resistance B alone are connected in the controlled circuit, for example that of a valve filament. Alternatively the contact arms may move over studs connected to the resistances, these studs being arranged in concentric circles, or one set may be mounted face to face with the other set.

Title: A Machine for Folding the Edge of a Flexible Material
Inventor: BOCCA ALBERTO
IPC: A43D8/40
Filed: 1968-03-05
Abstract: 1,198,914. Folding edges of sheet material. A. BOCCA, and M. PAGANI. 5 March, 1968, No. 10754/68. Heading B5K. A machine for folding the edge 26 of a flexible workpiece 15, e.g. a footwear insole, comprises a work-table 14 provided with an abutment 25 rising therefrom to define a curved surface against which the workpiece is pressed to start the folding over of the edge 26, a presser foot 16 for pressing the workpiece 15 against the abutment 25, and a reciprocable member 27 which engages, during every cycle, the edge 26, which has already been partially folded against the abutment 25, to complete the folding, the member 27 being actuated by a motor of the machine and having its direction of reciprocal motion substantially perpendicular to the direction of advance of the workpiece 15 along the table 14. As shown, the workpiece comprises a thin layer 15 the edge 26 of which is to be folded over a thicker layer 45. A header 13 overhangs the table 14 and carries the presser foot 16 affixed to a lever 17 pivoted at 18 and carrying a pivot 19 housed in a slot 20 in one arm of a pivoted lever 21 the other arm of which is vertically slidable in a fixed slot to engage and disengage the foot 16. The member or bar 27 is provided, at one end, with a radiused tip and is pivoted, at the other end, at 28 to a vertical rod 29 and is maintained horizontal by a spring 30 fixed to a tensioning device 39 secured to the rod 29 by a set screw 31 which also connects a bar 32 to the rod 29. The bar 32 is urged to the right of Fig. 2 by a spring 34 and carries a block 35 formed of two parts 40, 41 connected by a set screw 42 whose head is slidable in a groove 43 in a cover plate 44. The part 41 carries a bearing 36 which is urged, by the spring 34, against a cam 37 keyed to the mainshaft 38 of the machine. The rod 27 rests against a rocker arm 47 pivoted at 48 and carrying a tooth 49 adapted to engage a tooth 50 on a clamp 51 vertically pivotable in a plane perpendicular to that in which the arm 47 oscillates. In operation, the cam 37 moves the rod 32 and thus the bar 27 engages and folds the partially folded edge 26. When the bar 27 reaches the extreme right (as viewed in Fig. 2) of its movement, the clamp 51 is rotated so that the tooth 50 engages the tooth 49 to rotate the arm 47 and urge the bar 27 upwardly against the action of the spring 30. Thus, the return stroke of the bar 27 takes place without the bar sliding on the already folded edge 26. As the bar reaches the extreme left, the clamp 51 disengages the arm 47 so that the spring 30 lowers the bar 27 and a hammer (not shown) advances the workpiece.

Title: Improvements in processes and apparatus for hot galvanising steel strip by immersionin a bath of molten metal

Abstract: 1,145,223. Galvanizing steel. SOC., ANON. DES HAUTS-FOURNEAUX DE LA CHIERS and SOC. ANON. PROMETO. March 9, 1967 [March 9, 1966; Feb.14, 1967], No.11181/67. Heading C7F. The crystalline relief structure known as "spangle" is prevented from appearing on hotgalvanized steel strip by coding the zinc-coated strip, before the coating has begun to crystallise, by a dry method and more rapidly than can be achieved by coding means employing air at room temperature, from a condition in which the zinc is still molten to a temperature below that at which it would normally crystallise. This is preferably done by passing the coated strip through cooled rollers 8, 9 after it emerges from the galvanizing bath and at a height intermediate between the bath surface and the point where spangle would otherwise appear on the upwards-moving strip. Rollers 8, 9 even the thickness of the zinc coating and give the surface of the coating a finish corresponding to their own. They may be moved apart and together, or adjusted vertically and may meet either with their centres at the same level or vertically staggered. The vertical and horizontal adjustments for the rollers may be independent of those for each other, or may be linked so that a horizontal or vertical adjustment can be made using one control for both rollers.
