Title: Diaphragm spring clutch assemblies
IPC: F16D13/58
Filed: 1964-02-06
Abstract: 1,000,168. Diaphragm springs; friction clutches. GENERAL MOTORS CORPORATION. Feb. 6, 1964 [Feb. 18, 1963], No. 5039/64. Headings F2C and F2S. A diaphragm spring for a clutch assembly comprises an annular frusto-conical portion 30 integral with a plurality of inwardly-projecting spring fingers 31 which are symmetrically distributed around the inner perimeter of the frusto-conical portion 30 and each have the centre of gravity of their effective mass disposed outside the included vertex angle of the annular frusto-conical portion 30. The spring fingers 31 are formed by slots 44 cut in the spring plate and openings 45 to accept pivot pin mountings, the fingers being bent intermediate their lengths at 32. As shown in Fig. 1, a flywheel 10 on an engine crank-shaft 11 carries a clutch cover 12 having a pressure plate 13 secured thereto by flexible drive straps 16 and bolts 17. A driven disc 21 is splined on a driven shaft 24. A diaphragm spring 26 is mounted on pivot pins 27 on the cover 12, pivot rings 28, 29 being disposed around the pins 27 at either side of the spring 26 to serve as a fulcrum for the pivoted movement of the diaphragm spring. Spring clips 25 clamp the outer edge of the spring to the pressure plate. In the process of assembly the frusto-conical portion 30 is flattened in its region between the ring 29 and its point of contact with the pressure plate 13 so that normally pressure is applied to the pressure plate 13 to clamp the driven disc 21. Under the influence of centrifugal action the fingers 21 tend to move outward to add to the normal spring force of the frusto-conical portion 30, the ends of the fingers being curved to cooperate with a clutch release bearing 36. Sufficient clearance should be provided to ensure that the spring fingers do not make contact with the release bearing throughout the operating speed range. In a more compact clutch assembly, Fig. 6 (not shown), the spring fingers are of curved formation.

Class 100(4) In a web feeding attachment for a typewriter a horizontal frame composed of members 1-4, Fig. 1, moves transversely with the carriage on rollers 5, Fig. 4, supported by an adjustable rod 6, 7, Fig. 1. Carbon papers are attached to blades 15, 15a, mounted on a carrier 12 which moves on rollers 11 and is attached to a rod 18 which slides in a sleeve 19a. The web b is fed as shown in Fig. 2. A serrated tearoff edge 22, mounted on a pivoted subframe 23, Figs. 1, 4, is spring held in operative position, Figs. 1, 2, and inoperative position, Fig. 4. The web is initially fed through the machine by hand with the edge 22 in inoperative position, the web being held in a clip 28, Fig. 1, whilst the carbons are interleaved. In operation the webs and carbons are fed by rotation of the platen. When a form length is completed the pressure rollers are released and the rod 19, which has been moved forward by the carbon papers, is pushed back, withdrawing both webs and carbons. When the leading edge of the webs is clear of the platen, the edge 22 is swung up into inoperative position by pushing on a handle 26, thus lifting webs b, as in Fig. 4. A handle 20 is held to prevent the carbons from moving whilst the webs are drawn forward the required distance for detaching the typed form length. The tear-off edge is now moved into operative position and held there by handle 26 whilst the typed form is torn off. The next form length may now be fed round the platen and the cycle repeated. Several form lengths may be typed before being detached. Specification 800,785 is referred to.

Filed: 1969-01-31
Abstract: 1286871 Shaped particles UNITED KING- DOM ATOMIC ENERGY AUTHORITY 15 Jan 1970 [31 Jan 1969] 5500/69 Addition to 1175834 Heading C1A A material containing metal other than as free metal is made by (a) forming a viscous aqueous solution of a metal salt and a polymer containing a plurality of OH groups (other than a cellulose derivative which increases in viscosity in presence of an alkaline solution), the solution containing a complex of the polymer with metal ions; (b) shaping the viscous solution (e.g. by dropping or extrusion); (c) precipitating the metal ions as a water-insoluble inorganic compound from the solution and from the complex by contacting the formed shape with a reactive gas introduced from a source external to the vessel in which the precipitation takes place. Specified reactive gases are NH 3 , H 2 S and organic amines, e.g. methylamine. The reagent may be mixed with a non-reactive diluent, e.g. air. Mixed compounds may be produced by using a mixture of reactive gases or a mixture of metallic ions in the viscous solution. In one embodiment, gelled spheres or "gravel" is formed by dropping or extruding the viscous solution down a column containing stationary, or a counter-current stream of, precipitating gas. The gelled particles may fall on to a porous surface through which the gas is passed, or on to a moving band, or into liquid, e.g. water, through which gas is bubbled, in which case precipitation may be continued by dissolved gas. In a further embodiment, coatings of insoluble metal compounds may be formed by dipping objects in the viscous solution and exposing them to reactive gas. Examples describe the preparation of (1) spheres of hydrated thorium oxide gel from thorium nitrate solution containing dextran; (2) spheres of uranium diuranate from uranium nitrate solution containing dextran; (3) spheres of hydrated iron oxide gel from ferric chloride solution containing dextran; (4) hydrated aluminium oxide gel in the form of irregular gravel from aluminium nitrate solution containing dextran; (5) irregular gelled gravel containing iron oxide from ferric chloride solution containing carob gum. The reactive gas in all examples is ammonia.

Filed: 1921-02-18
Abstract: 177,013. Hackett, H., and Cadbury Bros., Ltd. Feb. 18, 1921. Pile tables and supports for sheet feeds. - In feeding perforated or shaped cards to computing machines for statistical purposes, the cards are fed from the bottom of a channel by known feed-mechanism which acts on the bottom card of a comparatively small stack above which is supported by auxiliary mechanism the major portion of the stack, a number of cards being dropped automatically at intervals from the major portion of the stack to the lower portion from which the feed takes place. As shown, a major stack d of cards is supported in a channel a formed as an extension of the receptacle which contains a small pack of cards b. The stack d is carried by pivoted supports c, the pivots of which are joined by a link e and are adapted to be operated by a cam g and lever f when it is desired to replenish the pack b. The action of the supports c is controlled by a roller x, Fig. 4, on a slide w connected to a spring- controlled lever v which presses the roller towards the pack b. When the pack b descends far enough the roller x moves to the left and motion is transmitted to a lever u which releases a catch t and throws in a clutch for driving the camshaft g. On this shaft is also a cam which operates levers j, m connected to a knife k, and a pusher l. Prior to the release of the sheets by the withdrawal of the supports c, the knife k is forced into the stack d and supports this stack while the cards below are released to replenish the stack b. The arm v and slide w are moved away from the stack b at each operation of the feeding slide, and during this operation the clutch which drives the cam-shaft g is declutched after the supports c and knife k are returned to the normal positions shown.
