Title: Improvements in making lock washers
Inventor: BEART ROBERT WOODWARD
IPC: B21D53/20
Filed: 1956-05-07
Abstract: 822,035. Making lock washers; punching; stamping. ILLINOIS TOOL WORKS. May 7, 1956, No. 14101/56. Classes 83 (2) and 83 (4). An external toothed lock washer, Fig. 11, is made by forming from sheet material an annular blank 88, Fig. 5, having tooth elements 80 on its inner margin, pressing the blank into a cone, Fig. 12, opening it into substantially cylindrical shape, Fig. 13, and then drawing the cylindrical blank to form a washer having external teeth, Figs. 15-17 (not shown). A metal strip 44, Fig. 1, preferably of spring steel, is fed between lower and upper die blocks 30, 32 where at a first station 34 a central hole 54 is punched by punch and die 48, 50. The strip is advanced and at a second station 36 a ring of holes 66 is formed by a punch 58, 60 whilst the strip is located longitudinally by a pilot pin 56 engaging in a previously formed hole 54. At the next station 38 radial cuts 78, Fig. 5, joining the holes and forming teeth 80, are cut by a punch 68, 74 and co-operating die 76; at station 40 a blank is sheared from the strip at 86 by punch 82 but is still retained in position in the strip, and at station 42 the blank is removed from the strip and pressed by dies 90, 92 into frustoconical shape. An ejector 100 removes the conical blank, which discharges into hopper. From the latter the blanks are fed successively down a shoot 116, Fig. 3, to a turret press 118, 120, Fig. 4, having work stations 104-114. The blank is gripped and moved successively between the stations by spring biased jaws 130, 132, Fig. 3, mounted on a rotary circular plate 126 secured to a ratchet-wheel 140 which is rotated stepwise by a pawl 144 carried by an annular gear 142 in mesh with a rack 148 which is actuated by a cam plate 162, Fig. 2 (not shown), secured to the upper moving member 120 of the press. At station 104, Fig. 4, the conical blank is drawn through a die 174, Fig. 4, into cylindrical shape, Fig. 13, by an upwardly moving plunger 178 and is then transferred by the fingers 130, 132 to station 106. During transfer a spring-biased locating finger 137, Fig. 3, rotates the cylindrical blank into correct angular position for reception by the next set of dies. At station 106 the blank is expanded outwardly into conical form with external teeth, Fig. 14, by dies 186, 188 including an ejector; at station 108 it is partially flattened, Fig. 15 (not shown), by dies 206, 208; at station 110 the blank is completely flattened, Figs. 10, 16 (not shown), between dies 220, 222, and at station 112 the teeth 80 are twisted, Fig. 17 (not shown), by dies 232, 234. The washers are finally discharged at station 114 The externally-toothed conical blank, Fig. 14, may have its teeth twisted and be used as a countersunk lock washer.

Title: Apparatus for producing bell-tones
IPC: G10H3/20
Filed: 1955-05-17
Abstract: 814,603. Simulating church bells. SCHULMERICH ELECTRONICS Inc. May 17, 1955 [May 17, 1954], No. 14235/55. Class 88 (1). In apparatus for simulating a swinging bell, of the type in which high-tone and low-tone plungers strike a small strip, the resultant sound being picked up by a microphone, amplified, and fed to a loud-speaker, the time interval between the energization of the plunger coils is varied by stops limiting the swing of a motor-driven contact operator. A clock-driven automatic bellsimulating apparatus, such as is described in Specification 814,088 and U.S.A. Specifications 2,582,441 and 2,582,244 has a number of strips 42, each arranged to be struck by high- and lowtone plungers 43, 44. When the corresponding synchronous motor, say 20F, is energized it drives a contact operator 23 in one direction until it comes against an adjustable stop 24R when the motor reverses to drive the operator 23 until it reaches stop 24L. The contact operator 23 deflects contact blade 30 in one or other direction to close contacts 31, 32 or 33, 34, respectively, so energizing either the high-tone or the low-tone plunger coil. The stops 24L, 24R can. be located in various apertures 28 and are rotatably adjustable whereby the times of swing can be varied considerably. The bells can be sounded individually by operation of push-buttons 66.

Title: Improvements in or relating to apparatus for use in the manufacture of vulcanised footwear
Inventor: TURNER FREDERICK THOMAS
IPC: B29C35/00
Filed: 1956-05-09
Abstract: 859,141. Moulding rubber soles on to footwear. C.I.C. ENGINEERING Ltd. March 11, 1957 [May 9, 1956], No. 14377/56. Class 87(2). A stationary last and movable side and sole mould components are mounted on a frame with pressure fluid circuitry for imparting movement to the mould components to open and close the mould formed by them, electrical switch means are operable by the moving mould components, and solenoid-operated valves impart movement through the fluid circuitry to the mould components, these valves being energisable by actuation of the switch means. In the twin-head machine of Fig. 2, two solenoid-operated fluid-control valves 1, 2 are provided, valve 1 being pipecoupled to cylinders 3 housing pistons 4 directly connected to side mould components 5. Valve 2 is similarly coupled to the two cylinders 6 housing rams 7 directly connected to the sole mould components. On closing the starter switch 10, solenoid valve 1 is energised and supplies fluid under pressure to cylinders 3 causing the side mould components 5 to close and switch 9 to be operated through projection 5B. The latter completes the circuit of timing mechanism 8 and holds closed the circuit of valve 1. Full closing of the side mould components effects operation through projection 5A of micro-switches 12, 13 which are in series to ensure closure of both mould components before valve 2 is brought into operation to raise the sole rams 7. After a preset period the timing mechanism 8 de-energises the solenoids of both valves 1 and 2 to permit the valve spools 1A, 2A which are biased by springs 1B, 2B to move in the reverse direction to fluid flow and thus open the moulds. The two-way switch 9 may be used in conjunction with either of the two outer mould components or may be duplicated to provide a two-way switch for each mould assembly. In a modified version, it is arranged for operation by the sole mould component.
Patent GB-907404-A (GB)
Title: Shaped articles of light metals or their alloys and process for their production
IPC: C22C1/04
Filed: 1960-04-25
Abstract: A process for the production of shaped articles of a light metal, and particularly magnesium, aluminium or their alloys, having a fine micro crystalline structure, is characterized in that fine particles of the light metal which contain in dispersed form fine crystallites of a solid insoluble metal phase are heated to a temperature within the range of plastic deformation of the light metal or alloy and ram-extruded with a substantial reduction in cross-sectional area, e.g. at least 80% of the compacted mass.  The grain structure of the light metal article is heterogeneous due to the presence of a finely divided crystalline metallic phase which is, at room temperature, insoluble in the light metal matrix and which is uniformly dispersed throughout the shaped article.  The aluminium or magnesium alloy contains at least 70% aluminium or magnesium respectively and the solid insoluble metallic phase corresponds to from 0.05 to 20% by volume based on the total volume of the light metal.  The fine particles of the light metal or alloy thereof are prepared by atomizing an alloy of the light metal to which has been added a small proportion of a metal or of an alloy thereof which is soluble in the melted or liquefied light metal but which is insoluble or only slightly soluble, preferably no more than 0.1% by weight, in the solidified light metal, such as gold, barium, beryllium, rare earth metals, palladium, platinum, antimony, selenium, strontium, tellurium, thorium, uranium, cobalt, germanium or silicon.  In an aluminium or aluminium alloy is distributed a solid insoluble metal phase of one or more of the metals gold, barium, beryllium, cerium, palladium, platinum, antimony, selenium, strontium, tellurium, thorium, uranium or an intermetallic compound of these metals with aluminium, e.g. AnAl2, BaAl4, CeAl4, PdAl3, SbAl, Se3Al2, Sr0Al4, Te3Al2, ThAl3 and UAl4.  In a magnesium or a magnesium alloy is distributed one or more of the metals barium, cobalt, germanium, antimony, silicon, strontium or of an intermetallic compound of these metals with magnesium, e.g. Mg9Ba, Mg2Co, Mg4Ge, Mg3Sb2, Mg2Si and Mg9Sr.  It is essential that the solidification of the atomized alloy takes place quickly in order to minimize aggregation or crystal growth of constituents which are insoluble in the solidified light metal.  To ensure this the molten metal is subjected to a dispersion and chilling operation to obtain fine individually frozen discrete particles.  The atomized metal is heated between 290 DEG  and 510 DEG C. for magnesium alloys and between 260 DEG  and 510 DEG  C. for aluminium base alloys in preparation for compacting and die extrusion.  Specification 662,312 is referred to.

Patent GB-576657-A (GB)
Title: Improvements relating to the manufacture of micro-porous material
IPC: H01M2/16
Filed: 1943-09-06
Abstract: Microporous material is produced by producing a dough by incorporating in a copolymer of a vinyl halide and another ethylene substitution product of the CH2=C< type, fine particles of a material which can be subsequently removed therefrom and a solvent for the copolymer which acts as a temporary plasticizer thereof, the resulting dough being then formed into desired shapes, the solvent removed and the solid dough treated for the removal of the particles so as to leave micropores in the solid copolymer.  Suitable copolymers are those of vinyl chloride with vinyl acetate, ethyl acrylate and vinylidene chloride.  The viscosity of the dough may be modified by the addition of a compatible liquid acting as a diluent for the solvent.  Specified materials, fine particles of which may be added, are starch and dextrin; specified solvents are methyl ethyl ketone and methyl cyclohexanone; and xylene is specified as a diluent.  The dough may be shaped by moulding, extrusion or rolling and the solvent removed by evaporation.  The starch or dextrin is swollen by treatment with hot water or hot caustic alkali and then removed by treating with hot sulphuric acid, or with an enzyme, e.g. malt diastase at 60 DEG  C., or with hot water for some time.  The shaped dough is then washed in water and dried, and it may be treated with a wetting-out agent such as a highly sulphonated oil before the drying.  Wood flour or the lignin bodies obtained from waste sulphite liquors in paper-making plants may be incorporated in the copolymer which may also have added a little carbon black.  The final products may be used as diaphragms or separators for electrical accumulators.

Title: Device for limiting the length of movement of tools of machines
Inventor: HILLMANN PAUL
IPC: B44B3/00
Filed: 1957-05-08
Abstract: 823,456. Engraving. ZEISS IKON DRESDEN VEB. May 8, 1957, No. 14637/57. Class 100(2) A device for limiting the length of movement of a tool of a machine comprises a housing, a sensing member mounted in the housing and extending therefrom, a stop pin urged by resilient means against an adjustable stop member which controls the vertical position of the tool, a catch device actuated by the stop pin, which catch device when actuated is fast with said sensing member and a coupling member arranged between the stop pin and the catch device, which coupling member is also actuated by the stop pin, whereby as the stop pin is moved towards a workpiece the sensing member engages the latter and is stopped thereby, whereupon the catch device is actuated by the stop pin and engages the sensing member in its stopped position whereafter the stop pin actuates the coupling member to bring the sensing member away from the workpiece, which sensing member serves as a bearing to terminate the movement of the stop pin and consequently the stop member and the tool. Vertically, slidable in a housing 1 is a stop pin 3 and a sensing member 2 with a head 2b resting on a shoulder of the pin', the member 2 being integral with or operatively connected to a sensing dome 2a. The pin 3 is urged to its upper position illustrated by a spring 5, and engages a stop member 4 connected to an engraving tool. The dome 2a is set a distance x above a workpiece 17, and the pin 3 depressed manually or automatically. When the dome 2a contacts the workpiece, the head 2b lifts off the shoulder of the pin, whereupon a presser plate 12 presses three balls 10 angularly spaced in recesses in the pin downwards, a bevelled face of a sleeve 9 forcing the balls inwardly to lock the head 2b and sleeve 9 together. On further downward movement of the pin 3, a levelled face 3b thereon forces three further balls 7 outwardly, which balls engage a bevelled face 9a of the sleeve 9 and force the latter upwardly a distance x 1 , whereby the dome 2a is raised a distance x, above the workpiece owing to the locking together of the head and sleeve. If the tool is now set to be a distance x 2  below the dome, with the stop member 4 contacting the pin 3, the depth of penetration of the tool will be x 2 - x 1 , regardless of changes in the height of the workpiece. In another form, the tool. can be carried in the housing on a bush surrounded by the sensing member in the form of a hollow cylinder with openings in its middle part, the upper parts of the opening resting on dogs connected to the bush and having lower bevelled surfaces corresponding to 3b, so that the dogs replace the stop pin and the parts 12, 10, 9 and 7, 9 act in the same way as in Fig. 1. The device can be arranged on a pantograph arm. Several of the devices can be arranged in a series to act on a plurality of workpieces.
