Title: Improvements in and relating to means for testing the gauge and cant of railway tracks
IPC: B61K9/08
Filed: 1928-07-23
Abstract: 317,967. Gurney, W. E. R. July 23, 1928. Linear-dimension gauges. - A machine for recording the gauge and cant of a rail track has a trolley T on one end of which is fitted a pair of single flanged wheels W<1>, W<11>, running on an axle A, the other end being adapted to be supported by a platelayeres' trolley or other convenient means by lugs F, F. One of these wheels W<11> can slide on the axle and is pressed by a spring S to keep the flange w<11>, which is of rectangular cross-section, against the rail head r. The extent of slide of the wheel is restricted by an adjustable collar S' on the axle. The sliding movement of the wheel moves in unison a graph rod m which works a style m<1> recording a graph on a moving sheet of paper G. A frame p<1> supports a pendulum P" which oscillates in a plane transversely to the track and which moves a graph rod N working a style n' recording on the moving sheet of paper, the graph rod being formed so that it exerts a damping effect on the pendulum. A small spring controlled plunger, not shown, operated by a Bowden wire is employed to mark the record sheet to locate positions on the track. The graph paper is driven through worm-gear or a single toothed wheel or cam from the axle of the machine by a toothed wheel engaging holes at the edge of the graph paper, a friction contact spring allowing the speed of revolution of the spool-holding wheel to vary with the diameter of the spool. The wheel flanges are lubricated by lubricating boxes V from which tubes V<1> pass to make sliding contact at their ends V" with the sides of the wheel flanges.

IPC: C22C1/10
Filed: 1974-05-15
Abstract: 1472479 Sintered composite metal-metal wire bodies SIEMENS AG 15 March 1974 [23 May 1973] 21657/74 Heading C7D In the production of dense bodies comprising a metal powder and metal wires, detrimental reaction between the metals upon heating is prevented by adding to or coating on one metal before, during or after forming the body, a substance which reacts with the other metal or with a coating on the other metal to form a product which is inert to both metals. Heating is then applied to form the inert reaction product. The substance may be O 2 , C, B, Si or N2 which reacts to form the metal oxide, carbide, boride, silicide or nitride. The substance may be added as a powder to the mixture e.g. C or Si or it may be diffused into the body and deposited from a gas such as a hydrocarbon or N 2 . A coating of Ti, Zr, Nb, Ta, V or Hf may be applied to one of the metals, this coating reacting with the substance to form the inert reaction product. In the examples C powder is mixed with Ni powder and W or Mo wires, the powder is compressed and swaged and then heated e.g. at 900‹C to form a WC or Mo 2 C inert layer. Alternatively a mixture of CH 4  and H 2  may be used to form the WC.

Abstract: 1,133,911. Making sheets. NORDDEUTSCHE AFFINERIE. 10 May, 1967 [12 May, 1966], No. 21813/67. Heading B3A. [Also in Division C7] A method of detaching electrolytically deposited sheet material from a base member, wherein the base member which carries the deposited sheet material on each side, is flexed without reducing the cross-section of the sheet material, by passing the assembly through a roller bending machine having at least three rolls. The base member 5 with deposited material 6 adhering to each side is passed between the rollers 1 and 2 of a bending machine. The rollers 1 are driven and the rollers 2 are adjustable thrust rollers. An idle straightening roller 7 is provided at the exit side of the pass. The material is brought to, and removed from, the roll pass by conveyers 3 and 4 respectively. By flexing the sheets within their elastic limit no additional straightening operation is subsequently necessary, but to ensure reliable separation it is preferable to flex the sheets beyond their elastic limit.
