Title: Improvements in or relating to blank feeding mechanisms
IPC: B65H9/10
Filed: 1937-01-21
Abstract: 473,941. Feeding articles from stacks. STEVENS, A. H. (Swift, Inc., G. W.) Jan. 21, 1937, No. 1821. [Class 117] In a machine wherein flat articles are fed from the bottom of a stack, the bottom article is pushed partly from the stack and means are provided to complete the withdrawal and deposit it on a device which feeds the main rolls of the machine which may, for example, be a printing or slotting machine. In the form shown, the blanks in the magazine 2, which are to be conveyed to the feed rolls 4 of a device for printing and/or slotting them, are individually pushed partly from the bottom of the stack by a reciprocating pusher 7 whereupon they are gripped by the rolls 6 which deliver them to the conveyer 10 slightly in front of the pusher bars 15. In a modification, an additional stage is introduced in the form of a second conveyer which transmits the blanks from the rolls 6 to the conveyer 10. Mechanisms for driving the rolls, conveyers, and the pusher 7 are described in detail.

Abstract: 555,344. Making hollow bodies. BRITISH THOMSON-HOUSTON CO., Ltd., BOURNE, H. K., and BEESON, E. J. G. Feb. 17, 1942, No. 2091. [Class 83 (ii)] [Also in Group XL] A hollow body of refractory metal such as tungsten or molybdenum, e.g. an electrode of a discharge lamp, is made by winding a wire of the metal required on to a mandrel of the shape desired with its convolutions close and then surface welding the convolutions, e.g. by an arc in hydrogen. The arc may be between the body and an external electrode or between two such electrodes and caused to impinge on the body by a magnetic field. Where an intricate shape is required it is wound to approximate form on a mandrel and pressed to shape before welding. The wire may extend from the body to serve as a support. The surface of the body may be finally ground. Specification 12731/00, [Class 83]. is referred to.

Title: Improvements in or relating to the coupling of power driven shafts

Filed: 1933-01-23
Abstract: 398,389. Adjusting bearings. YARROW, SIR H. E., c/o Yarrow & Co., Ltd., Scotstoun, Glasgow. Jan. 23, 1933, No. 2139. [Class 12 (i).] In coupling propeller shafts, whilst in motion to one or other of the engines electrical synchronization is first effected before the mechanical connection is made. In a marine plant, the main turbine F is coupled by dog couplings D<1>, D<2>, to the propeller shaft. On either side of the coupling are electrical units, one being a synchronizing motor E and the other the cruising motor C so that with the propeller shaft rotating, if it is desired to bring in the turbine F, the motor E is energized from the same A.C. generator as the motor C and then the propeller shaft is moved up for the dog members to be engaged. Movement of the propeller shaft involves a movement of the main thrust block B which is mounted to be movable longitudinally. In order to effect this movement hydraulic rams J are employed and according to the position of the block, wedge keys M are inserted between stops L or K in order that the casing may then take the thrust reaction.

Title: Improvements in or relating to hydro-kinetic transmissions
Inventor: BURNETT STANLEY FREDERICK
IPC: F16D33/10
Filed: 1966-01-19
Abstract: 1,130,461. Fluid couplings and converters. SELF-CHANGING GEARS Ltd. 18 Jan., 1967 [19 Jan., 1966], No. 2565/66. Headings F2C and F2D. ' To control the volume of fluid in a torque converter or, as shown, a fluid coupling comprising an impeller 2 and turbine 3, each discharge aperture 20 is formed by the overlapping of a straight slot in a sleeve 19 and a helical slot in a valve member 18 rotatable by a rack and pinion 16, 17 to adjust the radial position of the discharge aperture, thus determining the level of fluid in the coupling, the overflow being discharged from member 18 into a non-rotating casing 1. Control.-The fluid is fed from the casing 1 through a filter 5 by a pump 6 to a spring- biased pressure limiting valve 7, the excess fluid being fed through line 7c and a selector valve 9, spring-biased to its central position, back to the casing 1 through line 9h, and to an on-off valve 8. Fluid flowing from valve 8 enters a pressure regulating valve 12, biased to the left by line pressure 8b and to the right by a spring 12b and a cam 13. A valve 10 is arranged, as shown, to exhaust fluid pressure from a cylinder and piston 14 controlling a ring 15 carrying the rack 16, and from the right-hand end of the selector valve 9. The on-off valve 8, the cam 13, and valve 10 are formed on a common spindle and are operated simultaneously by direct manual or remote control. Operation.-On rotating the on-off switch slightly anti-clockwise, fluid is fed to the pressure regulating valve 12 and then through valve 10 to cylinder 14 and to valve 9. Initially the pressure is insufficient to overcome spring 15b in the cylinder and the apertures remain in their radially outermost positions, but fluid pressure 10c positions valve 9 so that 9 so that excess fluid from valve 7 flows through valve 9 to the coupling working chamber through line 11 and the hollow output shaft 3a, and then out of apertures 20. On rotating valve 8, and hence cam 13, further, fluid pressure 10b increases sufficiently to overcome spring 14b to rotate valve member 18 and move the aperture 20 radially inward permitting filling of the coupling through line 11. On closing valve 8, the apertures return to their radially outermost position, line pressure 10c is exhausted allowing valve 9 to return to its central position cutting off the coupling fluid supply, ensuring rapid emptying of the coupling. For two couplings, e.g. in a forward and reverse arrangement, the controls and valves may be duplicated so that one coupling is. emptied as the other is filled.

Abstract: 557,969. Amusement apparatus. SEBEL, H. Feb. 28, 1942, No. 2651. [Classes 136 (ii) and 136 (iii)] A model horse or carriage includes front and back legs supported on wheels rotatable in one direction only, and flexible means connecting said front and back legs so that by movement of a rider on said flexible means, said legs alternately rock towards and away from one another to produce a forward motion of the model. As shown in Fig. 1, steerable front legs 1 and back legs 2 are connected by oppositely facing semi-elliptic springs 6, 9, bearing respectively a saddle 8 and stirrups 12. The wheels have pawls and ratchets to prevent backward rotation. The rider's weight on the saddle pushes forward the front legs, and transfer of the weight to the stirrups shorttens the wheelbase to bring up the back legs. As shown in the other figures, the legs are rigidly secured to brackets 41, 42, carrying rigid arms 16, 17 and connected by a spring 6 to which is clamped the body 39 connected by links 40 to the front end rear brackets. As shown diagrammatically in Figs. 8 and 9 relative movement of arms 16, 17 is limited by cleats. The pawl and ratchet mechanism is replaced by trailing loops 38 to resist backward rotation.
