Abstract: 1,184,204. Fuel supply systems. E. C. ADAMS. March 20, 1967 [March 21, 1966], No.12918/67. Heading F1B The fuel system of a motor vehicle engine capable of driving power take-off means 14 is provided with means to measure the amount of fuel used during the periods when the engine is driving the power take-off. In Fig. 1 the fuel for normal vehicle operation is supplied through pipe 26 direct to the pump 30 feeding the carburetter 28. Movement of lever 12 to activate the hydraulic power take-off means 14 admits pressure through pipe 24 to a piston valve 32 which diverts the fuel flow through a by-pass 46 containing a metering means 48. Valve 32 may alternatively be actuated when the vehicle hand-brake is applied, and may be actuated mechanically or by suction instead of pressures In Fig. 4 meters 48c, 48d, are provided in the main pipe to an injector 28d and in the section pipe 56b, 72, from the injector. During operation of the vehicle on the road, valves 38d, controlled by a vacuum connection 24c to a vacuum controlled brake or power take-off system, are set so that fuel flows directly from the tank 54b to injector 28d through pipe 70 and excess fuel from the injector returns through pipe 56b directly to the tank. When the vehicle is stationary and the brake or power-take means are in operation, valves 38d are moved by the vacuum in pipe 24c so that the fuel is fed to injector 28d through motor M and the return fuel from pipe 56b passes to the tank through a pipe 72 containing a second motor M, the fuel consumed by the engine being obtained from the difference in the meter readings.

Abstract: 133,736. Guy, H. L., and British Westinghouse Electric & Manufacturing Co. Sept. 17, 1918. Regulating.-In turbine wherein, when running at reduced speed, the steam or other motive fluid is admitted to an additional turbine section 16 before flowing by way of a passage 32 and nozzles 33 to the main section 15, the nozzles 33 for guiding the partly expanded steam from the section 16 to the main section 15 are separate and distinct from the nozzles 18 admitting live-steam to the main section 15, and are specially designed to produce a velocity suited to the reduced blade-speed. The sections 15, 16 may be divided from one another by a diaphragm 17 of the kind described in Specification 113,690. and the nozzle boxes on opposite sides of the diaphragm for admitting live-steam to the sections 15, 16 may be of the kind described in Specifications 105,370, 115,666, and 116,347. The section 16 may be arranged so that the steam flows therethrough in the same direction as through the main section 15. Modifications are described wherein, for running efficiently at three different speeds, an intermediate additional section is provided, together with additional nozzle boxes. Any number of additional or speed-varying sections may be employed. In the application to a turbine of the reaction type having partial admission, the segmental rows of stationary blades terminate in end blockings, and those portions of the rings of stationary blades of the main section between the end blockings through which the steam from the additional section flows are differently designed from the other portions. For overload purposes, live-steam may be admitted to both main and additional sections.

Title: Improvements relating to the stringing of lawn tennis and like rackets

Filed: 1929-04-30
Abstract: 332,920. Prosser & Sons, Ltd., T. H., and Jaffe, W. E. B. April 30, 1929. Rackets.-Comprises a method of stringing tennis and like rackets in which the frame is held against both lateral and longitudinal distortion while both the main and cross strings are strung. The frame is held by a series of pins against its inner profile while the racket is completely strung by hand, the correct tension being placed on a string by a variable tensioning device. A pedestal has an arm b carrying a spindle c on which is rotatably mounted a cross bar e<1> to which is fixed the annular frame e. Segments f pivoted at f<1> on the frame e and a fixed segment g carry upstanding pins h adapted to abut against the internal profile of the racket frame d shown in dotted lines in Figs. 3, and 4. The ends of the segments f remote from the pivots f<1> are fixed to cranked arms f<2> connected to the plungers i which slide in guides e<2> and are connected to the flanges j', j<2> of the pivotal collar j by pins i<2> extending through cam slots j<3>. The collar j may be rotated through the worm k<1> and worm-wheel j<4> by turning the tommy bar k<2>. Thus rotation of the collar in one direction will cause the plungers i to move outwards, forcing the pins h against the racket d, in which position the racket is strung, the initial positioning of the racket aided by the clips e<5> being such that the pins h grip the racket frame between the stringing holes. To obtain the correct tension on each string r it is wound round the cleats l<1>, Fig. 7, fixed to the winding drum l rotatably mounted in the head m pivoted at m<3>. The drum l is then rotated by the worm l<3> increasing the tension on the string r until further rotation of the worm l<3> causes the head m<1> to tilt. The tension at which this occurs may be varied by a weight sliding on a horiozntal pivoted lever, the free end of which is pivotally fixed to the arm n<1>. When a. string r is thus stretched, the hole in the racket frame d is plugged, the string threaded through the next hole, and the racket, still held in its jig, is turned about the spindle c when the string is again stretched to the requisite tension. When string- ing is completed the undistorted racket is released by rotation of the bar k<2>.

The wheel a is mounted on a slide b movable by means of a crank-pin e operated by a handle d to withdraw the wheel from the work h to engage the trueing tool g, and again to return the wheel up to the work. When the wheel is brought up to the tool g the throw of the crank-pin is adjusted by a screw f so that the wheel is trued properly.

Granular material is moved towards an outlet 20, Fig. 1, of a container 10 by scrapers 30 attached to bars 27 mounted between chains 26. The scrapers are suspended by chains 31 and the chains 26 pass over sprockets 25, 28 which are spring-urged apart to maintain the chains 26 taut. The construction of the scrapers is shown in Figs. 4, 5. The flange 34 and a similar portion of the scraper shown in Fig. 5 may have a serrated edge. Whilst the container is being loaded through an orifice 11, closed by a lid 12, the scrapers are driven in the reverse direction to ensure even distribution of the load.
