Title: Improvements in brake apparatus for railway vehicles
IPC: B61K7/20
Filed: 1925-10-02
Abstract: 260,405. Farenc, J. Oct. 2, 1925. Skid; scotch blocks and scotching appliances. - Relates to brake apparatus for railway vehicles of the kind in which a shoe disposed on the rail for engagement with the vehicle wheel is adapted to be withdrawn automatically laterally from beneath the wheel at a predetermined point, and consists in the provision of a, guide rod for the shoe which may be moved away from the track rail automatically or non-automatically to effect the withdrawal of the shoe or may be used in conjunction with an additional rail having a diverging part by which the shoe is withdrawn. Means for returning the shoe automatically are described. According to Fig. 2, the shoe 1 rests upon the rail 2 and is guided by a rod 4 which is connected to links 6, 6<1> pivoted at fixed points 7, 7<1>, the arrangement being such that when the shoe, after having been carried along by the wheel to effect braking, reaches the end of the rod 4, this rod is moved longitudinally and laterally and thus withdraws the shoe from beneath the wheel. An additional rail 2<1> and a plate 10 are provided to support the shoe during the removal of the shoe. A counterweight 11 at tached by a cable to the shoe serves to return it to the original position after it has been withdrawn from the wheel. Springs 13, on the guide rod 4 prevent shock. By means of a cable 14 the rod 4 may be moved by control from a distant point to withdraw the shoe from the wheel at any point or to keep it out of action when not required. Figs. 6 and 7 show another construction according to the movable guide rod 4 for the shoe is carried by vertically swinging levers 6, 6' pivoted at 7 and normally held against the supporting rail 2<1> by spring 22, 22<1> on guide rods 23, 23<1>.Disengagement of the shoe from the wheel is in this case effected automatically by a diverging guide 18 engaged by a part 17 on the shoe. A spring 20 on the guide rod 4 effects the return of the shoe to the original position after its disengagement from the wheel. A ramp rail 19 with inclined ends 19<1>, 19<11> may be provided for raising the wheel from the shoe during its disengagement. The disengaging guide 18 may be movable along the track to enable the point at which the shoe is withdrawn to be varied. The rod 20 may also be moved to put the shoe in or out of action by an electric, motor 25 connected to the rod 23<1> or by a cable or hydraulic means. The guide rod 4 may be mounted on a fixed vertioal pivot at its rear end so that it assumes an inclined position in relation to the track rail when the shoe is withdrawn from the wheel.

Title: Improvements of and relating to injection type rotary piston internal combustion engines of trochoidal construction
IPC: F02B55/14
Filed: 1961-07-12
Abstract: 964,108. Rotary-piston internal combustion engines. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. July 12, 1961 [Aug. 2, 1960], No. 25200/61. Heading F1F. A rotary piston fuel-injection, I.C. engine of trochoidal construction, comprising a threelobed piston 3, Fig. 2, rotating about its own axis 4 and having planetary movement about an axis 5 over the contour 1 of a two-lobed casing 2 having an air intake 10 and an exhaust outlet 11, comprises a combustion chamber 16 offset from the working chamber 9 and located adjacent the junction of the working chamber with the compression chamber 8. The chamber 16 which is cylindrical in shape and extends the entire width of the piston is formed with a narrow neck 17 and a straight portion 21 tangential to the chamber 16 and at an angle a to the vertical axis of the chamber to direct the air flowing into the combustion chamber towards its wall to produce rotational flow of the air. The fuel-injection nozzle or nozzles is or are also disposed tangentially to the chamber 16 to produce rotational flow of the fuel. The neck 17 is located so that the piston edge 13 in passing from the compression chamber 8 to the working chamber 9 allows flow of gas from the former chamber to the latter. To permit easy starting of the engine from cold, the volume of the combustion chamber may be decreased by a pair of inwardly moving pistons to raise the compression in the chamber and hence the temperature. The pistons may be operated automatically by means of a thermostat in response to temperature.

Abstract: 424,014. Thermal switches; partly electromagnetic switches. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin) Sept. 12, 1933, No. 25242. Convention date, Sept. 12, 1932. [Class 38 (v)] Change of temperature such as room temperature causes the bimetallic strip 1, which is of magnetic material or carries an armature at its end, to bend down against the force exerted by an electromagnet 5 till its contact 7 engages a fixed contact 6. The electromagnet is then short circuited so that increased pressure between the contacts is obtained. A large current can now flow to the heater 8 and as the temperature of the room rises the contacts 6, 7 separate, the magnet 5 becomes re-energized and helps the break. In a modification, Fig. 2, a magnetic coil 5 magnetizes both the bar 15 and the bimetallic strip so that the two contacts repel each other. The Specification as open to inspection under Sect. 91, describes other constructions in which the magnetic force reinforces the contact pressure. This subject-matter does not appear in the Specification as accepted.
