Title: Improvements in or relating to couplings between coaxial rotary shafts
Inventor: GIESZCZYKIEWICZ STANISLAW MARI
IPC: F16C32/06
Filed: 1964-09-18
Abstract: 1,112,113. Shaft couplings. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 7 Sept., 1965 [18 Sept., 1964], No. 38193/64. Heading F2U. [Also in Division F1] In a radially toothed coupling accommodating relative axial movement between coaxial or substantially coaxial shafts, in particular adjacent rotor shafts of steam turbines, comprising complementary long and narrow radially outwardly and inwardly extending teeth 37, 55, respectively, of an inner clutch part 35 and an outer clutch part 53 secured to a flanged hub 47, oil is continuously centrifugally forced through ducts opening midway of the active tooth surface of the outwardly or, as shown, inwardly extending teeth to form torque transmitting oil layers. The active tooth surfaces may be flat or curved, radial or inclined to radial. As shown, the flanged hub 47 and the inner clutch part 35 are respectively shrunk and round-keyed on a high-pressure cylinder rotor HPR and an intermediate pressure cylinder rotor IPR. The teeth are straight-sided and the clearance curves between the teeth are approximately semicircular. The crests of the teeth 37, 55 are respectively flat and in the form of ridges bounded by twin concave end surfaces (Fig. 3, not shown). Oil is constantly supplied through a passage 69 in a bearing housing 67, and an annular space 75 defined by baffles 71, 73, to a catchment annular space 65, from whence it is centrifuged through passages 63 in the flanged member, and sealing bushes 61 into axially directed reservoir bores (57) one in the root of each tooth 55. The active tooth surface of each tooth 55 is formed with an axially extending oil distribution groove (58) connecting with equally spaced ducts (59) communicating with the reservoir bore. Oil leaking from the space 65 and discharged from the coupling teeth is collected in a guard 85 and a volute guard 81, the latter preventing oil spray recirculation. Sight boxes are provided in oil drains 87, 83, respectively, from the guards 85, 81. To increase mean oil pressure between the teeth the gap between the active tooth surfaces may be increased in the vicinity of the axially extending oil distribution groove (Fig. 5B, not shown). To achieve this, the tooth surface co-operating with the tooth surface provided with the oil groove is provided with a deformable resilient insert which may be of rubber or synthetic plastics such as polytetrafluoroethylene and should be resistant to wear at low speeds when the oil film collapses. Desirably these inserts are moulded in situ. The reverse sides of the teeth with the inserts may have further inserts and the coupling teeth may fit together with zero running clearance in the absence of torque and oil pressure. The resilient pads are preferably on the outer clutch part 53 so as to be retained centrifugally.

Abstract: 825,516. Riveting. SCHNEIDER, H. W. March 14, 1958 [Dec. 14, 1956], No. 38260/56. Class 83 (4). A method of riveting two components together in facial engagement, e.g. the coverplate 1 and the casing 2 of a miniature electric switch, wherein the components have preformed registering rivet holes comprises injecting into the rivet holes a thermoplastic synthetic resin by an injection moulding machine to form the rivets 3. The injection machine may be provided with a single nozzle 4 or twin nozzles for forming two rivets simultaneously (Fig. 1). The rivets are formed with a cheese head 8 at one end and a countersunk head 9 at the other end. For forming a tubular thermoplastic rivet an upstanding peg-like protuberance 11 is provided on the upper surface of the jig 10 (Fig. 4). After the sprue 12 has been removed a screw or the like is passed through the rivet to mount the switch on a panel. Specifications 592,480, 592,481, 644,265 and 765,556, [all in Group XXXVII], are referred to.

Title: Improvements in friction gearing
IPC: F16H61/664
Filed: 1930-12-19
Abstract: 369,657. Variable-speed friction gearing. GENERAL MOTORS RESEARCH CORPORATION, Detroit, Michigan, U.S.A. Dec. 19, 1930, No. 38370. Convention date, July 21. [Class 80 (ii).] Relates to variablespeed friction gearing having precessional rollers such as 41, Fig. 1, engaging driving and driven toric races such as 36, 35 in which the rollers are mounted on trunnions passing through the centres thereof and adjustable by a control lever, not shown. The invention comprises means incorporated with each trunnion providing an oblique axis about which the roller can tilt to terminate the precessional change in a position of equilibrium. The roller 41 is supported from a fixed spider arm 29a on a positioning arm or lever 72 which rocks in a plane normal to the axis of the gearing about a pivot 76 as described in Specification 369,650. The lever 72 has two flat faces 77, Figs. 4 and 6, nearly but not quite parallel to the section of Fig. 1. Upon the outwardly-set oblique faces 77, inwardly-set faces of trunnion blocks 67, Figs. 4 and 7, are adapted to slide radially and to turn. The blocks 67 are supported in a ring 66 forming the inner race of a ball bearing 65 supporting the roller 41. Fig. 11 is a diagram showing exaggerated the obliquity of the permanently oblique axis TT provided according to the invention normal to the working surfaces 77 of the lever 72. When the lever 72 is rocked by the manual control downwardly of Fig. 11, the point O at which the axis of the roller 41 intersects the gearing axis RR moves to a point O<1> clear of the axis RR. The roller being inclined to circular treads on the toric surfaces, precesses in spiral paths so as to turn on the surfaces 77 about the axis TT until the axis of the roller again intersects the axis RR at a fresh point P. Precession then stops because, in the new position of the rollers, the latter run round and round on circular treads on the toric surfaces.

Abstract: 1407454 Casting composite articles GLOBE UNION Inc 17 Aug 1972 [27 Oct 1971] 38477/72 Heading B3F [Also in Divion H1] A machine used in the interconnection, by burning, of lugs 93, 94 on battery plates 79, 80 involves three stations I, II, III between which a rotatable part of the machine holding the plates is successively moved. The stations I, II, III serve, respectively, for loading, burning, and unloading, the plates. At station I (see Fig. 1) the battery plates 79, 80 and separators (not shown) are loaded into one, 11, of three identical boxes 11, 12, 13, corresponding to the three stations (shown in detail in Fig. 7). The box 11 is mounted so that it may be pivoted about a near-diagonal axis 19-19; it is released from twolowermountingprints 20 to allowthis. Thebox 11 is moved to the loading position (dashed lines in Fig. 3) by a pneumatic piston 50, 51. The tilt angle produced lets the plates settle against the back wall and one end of the box. Fig. 7 shows the spiked clamping rods 80, 81 and a bottom plate 150 co-operating with slots 151 and grooves 152 which allow for the insertion of different numbers and sizes of cell plates. As shown two cell units 195, 196 are being produced. The box door is held shut after loading by standard clamps 75 (omitted from Fig. 7). An operator pushes the machine by hand to rotate the three box units about a vertical post assembly 16 so that the newly loaded box comes under table 100 at which the lugs will be interconnected by burning (station II). An indexing mechanism on the table and controlled by handle 86 drops a pin into a hole 91 on one of the box-pivot support arms 27. The operator then loads the empty box which he receives from unloading station III. The box 11 (12) (13) is raised to working height under the table by pneumatic pistons 55, 58 (Fig. 3). The operator works at the table 100 which incorporates comb bars 114, 118 co-operating with mould bars 103, 102 to define open-topped spaces (Fig. 4, not shown) within which the lugs 93, 94 may be melted together to form straps 127, 128 by a gas torch and terminal posts 129, 130 inserted; also, additional lead is added. The comb and mould bars may be changed to accommodate plates and lugs of different size and/or spacing. The top of the table 100 is held by screws and slots 190<SP>1</SP> to allow adjustment for this purpose also. The comb and mould bars are moved together or apart by hydraulic pistons 127a, 128a operating on slide bars 121, 122. After the burning operation the box 11 lowered, and the machine rotated to bring the box to the third station III. Here the operator equipped with a hoist (shown only in Figs. 9 and 10) having spring loaded fingers to hook under the newly formed connector straps 127, 128 lifts the completed cell unit from the box and subsequently inserts it into a battery case which is covered and then filled with electrolyte. Alternatively, the bottom of box 11 is removed and the cell unit dropped through. At the next rotation of the machine the now empty box 11 is returned to the first station I for reloading.
