Title: Improvements in or relating to internal combustion engines of the free piston type
IPC: F02B71/00
Filed: 1945-05-10
Abstract: 593,051. Free piston engines or gas generators. SULZER FRERES SOC. ANON. May 10, 1945, No. 11721. Convention date, May 12, 1944. [Classes 7 (i) and 7 (ii)] A free piston engine has one or more free pistons and two or more energy storage or buffer cylinders of which at least one absorbs energy during an outward stroke of a free piston and at least one absorbs energy during an inward stroke of a free piston which energies are accumulated by a pressure increase in each buffer cylinder at least in the latter part of the stroke and means are provided for controlling these pressure increases so that the frequency of the stroke can be altered. In the case of an opposed piston, free piston engine one piston may have a buffer cylinder acting on the outward stroke and the other a buffer acting on the inward stroke. As shown a piston 25 working in an engine cylinder 26 has connected thereto a compressor piston 27 and a buffer piston 29. One side of the compressor piston draws in air through a pipe 31 and supplies it to the engine at 34. The other side of the compressor piston acts as a buffer cylinder which works in opposition to the buffer cylinder 30 associated with the piston 29. The buffer cylinder 30 is supplied with air or gas under pressure through a pipe 47 and pressure regulating device 46 which keeps the pressure constant. When the piston passes the pipe 45 on the outward stroke the air or gas supply is cut-off and the gas in the cylinder compressed. The -buffer cylinder behind the compressor piston has a number of ports 36 therein. A valve 41 can be arranged to close all or some of these ports so that the point at which compression in this cylinder is started can be varied. A pipe 37 leading to the ports can be connected to atmosphere or to a source of gas under pressure or alternatively this cylinder can receive air through a valve 35 and by suitably positioning a cock 38, the pipe 37 can be. connected to the engine scavenging air ports so that the buffer cylinder compresses and supplies air to the engine for scavenging. A modification is shown in which an opposed piston, free piston gas generator has separate pressure regulating devices for buffer cylinders at the rear of the compressor pistons and for buffer cylinders associated with further pistons connected to the compressor pistons. The regulating devices may be controlled together and conjointly with the fuel supply by a hand lever. A buffer cylinder in which the end is adjustable to vary its volume is described. A hand operated valve may be provided to put a buffer cylinder in communication with the atmosphere if required such as at starting. Modified arrangements are described for regulating the pressure in the buffer cylinder and varying the point at which compression commences is this cylinder. A double acting buffer cylinder and piston arrangement is described.

Title: Improvements in Machines for Truing Loom Shuttles.
IPC: B24B19/16
Filed: 1918-12-20
Abstract: 126,962. Stõubli, Geb. Dec. 12, 1918, [Convention date]. Disk apparatus; spindles &c., treating. - The pointed ends of a loom shuttle W are applied to a grinding-disk 2 in order to be re-shaped or trued. The forward end of the shuttle is carried in a semicircular roller-bearing 14 secured to a bracket 11, which is adjustable rotatably and vertically about a support 3, which in turn may be adjusted parallel to the axis of the grinding-disk along a bracket 4 carried by a transverse shaft 16. The rear end of the shuttle is held by spring clips 28 on a shaft 27, which may be retracted against springs 30 to release the shuttle. The shaft 27 is supported in a bearing 20 carried by a rod 15 mounted at one end on the bracket 11. A driving- cord passing over a tension device 24 conveys motion from a pulley 23 to a pulley 22 and thence through worm gearing 25, 26 to the shaft 27 and shuttle. By turning the handle 31 of an eccentric stud 31', the stud 27 can be uncoupled from the driving-gear. The end of the rod 15 is oscillated by hand between two abutments 17, 18 carried by a guide 19 mounted on the shaft 16, thereby causing the bracket 11 to swing about a nut 6 as fulcrum, and bringing the point of the shuttle into contact with the grinding-disk. The rod 15 may be actuated automatically, for instance by an eccentric; or the support 3 may be automatically traversed by means of crank-gear; or the grinding-disk driving-shaft may be moved longitudinally. When one end of the shuttle has been trued, it is reversed in the holder 28 and the other end is applied to the disk.

April 22, 1931, Nos. 11971/31, 19143/31, and 641/32. Addition to 351,071, [Group XXX]. [Class 103 (i).] Track apparatus for use in a train control and cab signalling system comprises permanent magnets and electromagnets arranged crosswise thereto and adapted to neutralize the effect of the permanent magnets, as by having their polepieces extended to lie adjacent the permanent magnet poles, or by the magnets crossing at an acute angle, or by the assistance of an auxiliary device which comprises an electromagnet lying parallel with the track-permanent magnets and acting against an auxiliary permanent magnet in a normally closed magnetic circuit to set up an external flux which then neutralizes the effect of the track permanent magnets. The track permanent magnets when effective actuate a magnetic receiver relay R, Fig. 10 (19143/31), to open a venting valve 109 and so initiate a braking and sound a horn 104 if a home or distant signal is not at clear ; at a distant signal the venting valve 109 is shortly afterwards closed bv restoration track permanent magnets located a little way ahead but a partial braking and horn signal continues which can only be cancelled if the train speed is such that a centrifugal valve device S closes its branch pipe to render an acknowledging plunger 120 effective to depress a diaphragm 105 and close the valve 107 which was opened when the spindle 112 of the train pipe venting valve 113 lifted. The centrifugal valve device comprises, as shown in Figs. 1 and 2 (11971/31), a chamber member 30 fixed to a wheel axle and having a spring-pressed weight member 11 provided with a valve 14 to close a port if the speed is below the limit. At a home signal at danger the receiver relay valve 109 is not automatically re-set and a full brake application ensues, the horn only being briefly operated on account of the large direct opening to the train pipe. The relay armature 102 and valve 109 can be re-set by a release plunger 103 actuating a diaphragm and lever device 101 ; this release plunger is only accessible when the train is stopped. Specifications 351,039, 351,072, and 353,502 are referred to.

Abstract: 289,834. Ganz-Fele Villamossagi RÚszvÚnytßrsasßg. May 3, 1927, [Convention date]. Regulation, automatic; systems depending on static transformers.-The voltage across a consuming device taking a wattless no-load current for example, a transformer 3, Fig. 1, or an induction motor and supplied by constant voltage mains 1, is made to increase as the load increases by including in its primary circuit a self induction coil 4 which is near saturation at no-load and absorbs more than 2 per cent of the terminal voltage. If E, Fig. 2, is the vector of the voltage of the supply mains and eo, Eo the vectors of the voltage across the coil and the transformer at no-lead, then when the load increases the vector eo changes to e1, thus causing Eo to increase to E1. The voltage across the coil 4 is less than four times its no-load voltage when the load is ten times the no-load current. The coil 4 may have a part of reduced cross-section, or an air-gap in its core or may be shunted by an ohmic resistance. Two coils of different characteristics may be used in series. For 3-phase currents, the three coils are arranged on the limbs of a single 3-limbed core and additional coils, one on each limb, are connected together in delta to overcome the third harmonic.

Abstract: 262,652. Larson, C. M., and Knopf, C. L. May 17, 1926. Testing viscosity and lubricating efficiency of liquids.-Comprises two parallel tubes one containing a standard liquid and the other being brought into communication with a receptacle containing the liquid the viscosity of which is to be compared with that of the standard, both tubes containing elements which move when the tubes are placed in certain positions and the movements may be compared. Two tubes 1<a>, 1<b> are pivoted about a point 3 so that they can be inclined and both contain spherical members 4. The upper tube communicates by a pipe 2 with the crank case of an engine, oil from which may be drawn into the tube 1<a> by a pump 5. The tube 1<b> contains a standard lubricating oil. The rate of movement of the members 4 when the tubes are inclined give the comparative viscosities of the oils. The standard oil is chosen so that when the members move at the same speed the oil in the crank case has practically exhausted its lubricating qualities. The apparatus need not be attached to a motor crank case but mav be used separately.
