Title: Improvements relating to freewheel devices
IPC: F16D41/12
Filed: 1958-07-08
Abstract: 848,600. Ratchet clutches. DAIMLERBENZ A.G. July 8, 1958 [July 10, 1957], No. 21885/58. Class 80 (2). A ratchet clutch for use in a gas turbine in a motor car or the like, comprises a driving hub 10 formed with frusto-cylindrical recesses 13 within which are rotatable clutch rollers 14 having arcuate faces 17 and constructed with their centres of gravity eccentric to the centre of curvature of their cylindrical faces, e.g. as by the removal of segments 18, rotation of the driving-hub 10 at a high speed anticlockwise of Fig. 1 causing the rollers 14 to turn under the influence of centrifugal force so that the arcuate surfaces 17 engage in recesses 19 formed in a driven ring 12 to transmit drive thereto. If the driven ring 12 tends to overrun the driving-hub 10, the rollers 14 are turned back to their disengaged position against the bias of centrifugal force, and free relative rotation between the driving and driven parts takes place. The driven ring 12 is journalled upon the driving hub 10 by a bearing 16, and a ring 15 holds the rollers 14 laterally in the position. The segments 18 removed from the rollers 14 to make their centre of gravity eccentric to the main axes of the rollers do not extend to the ends of the rollers, which therefore are solid. In modifications, Figs. 3 ... 8 (not shown), the eccentric weighting of the rollers is effected by the removal of additional bores of metal therefrom or by the insertion of pins of heavy metal, and the rollers are formed with pins at each end engaging corresponding holes in the driving-hub 10. Turning of the rollers 14 in one or both directions under the influence of centrifugal force may be limited by stops.

Title: Metallurgical processes for producing materials or articles of platinum or allied metals, or their alloys, and materials or articles produced by or from the products of such processes
Inventor: SMITHELLS COLIN JAMES
IPC: C22C32/00
Filed: 1944-11-08
Abstract: A metallurgical process consists in agglomerating by pressing and sintering metals of the platinum group with or without alloying ingredients in amounts yielding cold-working alloys with chromic oxide, the quantity of which oxide is not greater than 10 per cent by weight of the metal, all the ingredients being in a finely divided condition, the sintered body being subsequently swaged, rolled, drawn or otherwise treated to bring it to the form of wire or sheet suitable for the production of the desired articles.  A minor part of the chromic oxide may be replaced by one or more other oxides stable at the sintering temperature whether or not the sintering is carried out in hydrogen or other reducing gas.  The following binary alloys may be used, namely, platinum with up to 30 per cent of iridium, palladium or rhodium, or up to 15 per cent of ruthenium gold, cobalt or nickel or up to 8 per cent of tungsten, manganese or molybdenum. In an example 100 c.c.s. of distilled water containing 90 grammes of platinum in the form of a suspension of ammonium chloroplatinate is mixed with 50 c.c.s. of an aqueous solution of ammonium hexachlororhodate containing 10 grammes of rhodium and 10 c.c.s. of an aqueous solution of ammonium chromate containing 0.2 grammes of chromic oxide.  The mixture is made up to 200 c.c.s. with distilled water, dried, heated slowly to 350 DEG C to decompose the salts to metal and oxide and then to about 600 DEG C to complete the decomposition.  The product is crushed, heated to about 850 DEG C in a stream of hydrogen, sieved, pressed in a steel mould under a pressure of about 30 tons per square inch, sintered in hydrogen at about 1400 DEG C-1500 DEG C for about an hour and treated mechanically to bring it to the form of wire or sheet.  A further example is given of the production, in a similar manner, of a composition containing platinum, tungsten and chromic oxide.  The product may be used in the production of sparking plug electrodes, thermo-couples, electricfurnace heating elements and wire gauze catalysts. Specifications 645,541, 645,681 and 645,682 are referred to.

The stem coacts with internal threads in a cap 11 and passes through an opening which is grooved to receive an " 0 "-ring 15. The cap screws into the housing of the valve and is sealed by an " 0 "- ring 23 which becomes flattened.

A fishing reel comprises a back plate 12 supporting a spindle 11, a spool rotatable on the spindle and having a ratchet wheel 14, a stud 15 slidable in a slot (not shown) in the back plate between a check and a non-check position, a pawl 18 incorporating two operative portions and a kidney-shaped slot 20 for locating the pawl on the stud 15 in either of two alternative positions and a spring 21 adapted to cooperate with the pawl, the arrangement being that with the stud in the check position one of the operative portions of the pawl co-operates with the ratchet wheel to provide a right or left-hand check. The shank of the stud engages in one or other of the end portions 20a, 20b of the kidney-shaped slot 20 in the pawl and the spring 21 engages with one or other of two edge portions 18c, 18d of the pawl. The edges of the ratchet-engaging portions of the pawl are so disposed that a greater check is given to one direction of rotation than to the other. The spring 21 is anchored at one end to the back plate 12 and its other end co-operates with an eccentric element 22 mounted on the back plate and capable of angular adjustment to vary the action of the spring on the pawl. The eccentric element is locked by a screw passing through the back plate into a threaded bore in the element. When the stud is in the non-check position the pawl is out of engagement with the ratchet wheel.
