Abstract: 360,507. Clips. REICHENBACH, A., 7, Kaiser-Friedrichstrasse, Pforzheim, Germany. Aug. 14, 1930, No. 24357. [Class 44.] In the manufacture of fountain pen and like clips from a length of wire, a suitable length is severed, bent to form an eye (the joint of which may be soldered), tapered, flattened, the eye stamped out to the required diameter, and bent into a plane approximately at right-angles to the tapered limb, to the end of which a rounded member is secured, the successive steps being illustrated in Fig. 1. Alternatively, a terminal enlargement may be left integral with one end of the wire in the tapering process, and finally formed into a spoon &c. shape, Fig. 3, or rounded end, Fig. 4. In a modification the wire may be tapered and bent to provide two arms the ends of which receive a rounded hollow terminal body, Fig. 2. In a further modification, a length is shaped and slotted, the slot being then expanded to form the eye, Fig. 5. When the clip is made from wire coated with gold &c. severing may be effected by hammering a circumferential groove in the wire so that the coating is not removed and the ends remain coated.

Title: Improvements in or relating to valves for fluids
IPC: F16K27/10
Filed: 1960-07-15
Abstract: 938,548. Making valves. T. DE KONING. July 15, 1960 [April 2, 1960], No. 24650/60. Class 83 (2). [Also in Groups XXVIII and XXIX] A method of fabricating a valve unit by welding or brazing a valve casing, which is substantially symmetrical -about a plane passing through its longitudinal axis, to other components, such as pipelines, consists in effecting the welding, at at least one end of the casing, along a line that does not coincide with the original end face of the casing. A suitable valve comprises a casing having tubular parts 1, 3, Fig. 1, of different diameters and containing a guide 11, supported by bridge pieces 7, for a cylindrical closure member 9 of which the edge 13 is adapted to coact with a seat 6. One bridge piece contains a blind bore 16 for receiving, e.g. a thermometer whilst the other bridgepiece has a bore 15 communicating with a closed chamber 10 to which pressure fluid may be supplied for actuating the valve. The closure member, the opening of which may be limited by stops, may be loaded by a tension-spring in the chamber 10. The valve casing, which is made longer than would normally be required, may be shortened on either or both sides of the transitional section 5 between the parts 1, 3 before it is welded to other components. Lines (not shown) may be marked on the casing to indicate the limits beyond which the casing should not be shortened. A modified form of valve casing consists of a flanged, small diameter part secured by screws to the larger diameter part. In one embodiment of the invention the larger end of the casing is welded to a conical end cap and a pipe may be welded to the side of the casing or to the end cap. In another embodiment two valves welded together at 35, Fig. 7, may have their closure members interconnected by a ball-jointed rod 36. This rod may be omitted and one valve may then serve as a flow control valve and the other as a check valve. The two valve casings may be welded together with their axes in alignment and communicate at a point between the seatings with a third conduit. Other multiple-way arrangements involving up to eight valves welded together or to pipes are described. Fig. 21 shows a section through a manifold formed by plates as a triangular prism and carrying three valves 101 on one side and two valves 103 on another side. A comparatively large valve 104, Fig. 23, welded at its larger end to a conical end-piece 105 to which a pipe connection can be made is provided with a by-pass passage 109 incorporating a smaller, double valve arrangement 108, 110 for pressure equalization and venting &c. Fig. 24 shows a tank 111 to which the larger ends of inlet and outlet valves 112, 113 are welded and having a by-pass 116 welded to the smaller parts of the valves 112, 113 and containing a further valve 117. Flanges 114, 115 may be welded to the valves 112, 113.

Abstract: 921,649. Electromagnetic switches. ADMIRAL CORPORATION. July 7, 1961, No. 24754/61. Class 38 (5). [Also in Group XXXVIII]  An electromagnetic switch, for use in a remote control system comprises two coils 108, 100 which together act on a single double - fulcrumed 104a, 106a, armature 131 having a single contact 116, 118 at each of its two ends. The armature is spring urged towards the fulcra either by individual springs 128a, 129a, Fig. 3, over each of the fulcrum or by a central spring (as in Fig. 5, not shown). The coils are identical but because there are two fulcra, a weak current in one coil will balance a relatively strong current in the other and thus, for either of the contacts 116, 118 to be closed, the current through one of the coils must be considerably larger than that through the other. In a modification (Fig. 6, not shown) three coils are associated with a triply-fulcrumed armature.

Abstract: 668,814. Shearing. ARNOLD, C. (Robertson Co., H. N.). Oct. 13, 1950, No. 25092/50. Class 83 (iv). A machine for shearing sheet metal by slot cutting comprises driven and idle rotary cutters 10, 12, each having a pair of spaced parallel cutting discs and the driven cutting discs having teeth 19 co-operating with shoulders 22 of the idle discs to grip the metal along the marginal edges of the strip and effect self-feeding of the tool. Between the cutting discs the upper cutter is formed as a toothed wheel 34 which is driven through a chain of gears from a driven shaft 48, the cutter and all the gears being mounted in a housing comprising side plates separated by spacing members 58 and connected by screws 64. The lower idle cutter is mounted in a housing 80 pivotally mounted on the main frame by a pin 82 about which the housing may be adjusted by an eccentric 84 bearing against a hardened plate 86 and secured in position by means of a lever with a spring latch co-operating with a notched latch plate on the outside of the housing. Spring biased pivoted scrapers 124, 126 engage the upper and lower cutters. Lubricant is supplied to the gears through a nipple 146. In operation the tool is fed through the metal sheet 24 along the slot formed by cutting out the strip 30, the marginal edges of which are gripped between the teeth 19 and shoulders 22, the severed strip 30 being deflected through an outlet 32 by the scrapers 124 and 126 and by an idle roller 120. The housing has a portion of reduced thickness to permit the tool to pass along the slot and to be rocked up and down the corrugations of a corrugation sheet. The cutter may be attached to the frame of a portable electric drill 16.
