[Also in Division B8] Apparatus for loading and unloading gearshaving or milling machines, lathes or other machine tools comprises a two-armed gripper 24, Figs. 1 and 2 (not shown), reciprocating between machine tools or between a machine tool 20 and a transport belt or belts 22 and rockable about an axis perpendicular to the feed path and symmetrical to the arms. An hydraulically-operated lifting device 23 raises a workpiece from the conveyer belt, which is adjustable in height on legs 29, 30, whence it is transferred to the gripper head 24. The switchgear is mounted in a box 35 and a pushbutton panel 34 permits manual control. The finished workpiece can be returned to the same conveyer or one parallel thereto. The gripper head 24 is adjustably mounted on a slide 41, Fig. 4 (not shown), moved by a reversible electric motor 106 and a chain 107 (or an hydraulic drive) along a track 25 adjustably mounted on a pillar 32. The motor 106 drives through a resilient worm gearing allowing for sudden reversal. The gripper head has a housing 50 angularly movable on a shaft 43 and carrying gripping devices mounted on shafts 54 (Fig. 8, not shown). The housing 50 is movable angularly by a rotary hydraulic motor 48, the movements being limited by two adjustable stops coasting with two other stops, the positions of which can be controlled hydraulically to give a possibility of four positions. Each shaft 54 carries an angularly movable part 56 carrying a jaw 65 and a jaw 70 movable by fluid means or a spring 72 carried on an arm 68 movable by fluid means 62. When the housing 50 is oscillated, bevel wheels cause oscillation of the shaft 54. (Alternatively, separate hydraulic motors rotate the arms and the part 56 can be moved angularly by hydraulic means). Movement of the slide 41 towards the conveyers may be slowed and then stopped by an adjustable fixed stop engaged by a stop 117, Fig. 11 (not shown), adjustable on the slide and mounted on a dashpot piston 109. (When two conveyers are used, a second stop can be swung into position by hydraulic (or electric) means). Continuously moving belts 22a, 22b, Fig. 14 (not shown), carry workpieces up to a stop 138. When an electromagnet 147 (or an hydraulic or mechanical device) is actuated, the stop 138 is retracted, a stop 136 advanced and a stop 137 swung aside to allow a finished piece 21f to proceed. The workpiece 21f actuates a switch 150 to cause the stops to be repositioned so that the next workpiece is then against the stop 137. The conveyer belts consist of work support elements 166, Fig. 16 (not shown), carried by links running over adjustable supports 159 and 160. The edges of the workpieces are guided by adjustable strips 164.

Title: A device for lifting railway tracks
IPC: E01B29/04
Filed: 1959-05-01
Abstract: 907,547. Apparatus for lifting railway tracks. PLASSER, F., and THEURER, J. May 1, 1959 [May 28, 1958], No. 14961/59. Class 104 (2). In a device operated by pressure medium for lifting railway tracks the amount of lifting movement or lifting movement time is controlled in dependence on the pressure or the pressure variations occurring in the pipe supplying pressure medium to the lifting member. The apparatus operates in the following manner. A lifting cylinder 4 is pivoted about a pivot 8, on tha supply of pressure medium to a cylinder 9, to engage a lifting member 2 beneath a rail 1. A snap switch 28 is then operated to energize, from a battery 32, a pusher electromagnet 25 which pushes a slide valve 20 to the right so as to enable the pressure medium from a tank 16 to be supplied by a pump 17 through pipes 18, 22 to the upper part of the lifting cylinder 4. A piston 5 is moved downwards to press a bearing-plate 3 on to the ballast to lift the rail 1 by means of the lifting member 2. The pressure increase occurring in the pipe 22 as the result of the lifting operation is effective, through a pipe 43, in lifting a piston 40, against a spring 41, to close a switch 37 which energizes, from the battery 32, a slow-acting relay 35. The relay 35, according to a setting 36, controls the duration and the amount of rail lift. As soon as the set period of time expires the relay 35 closes the switch 34 which sends a signal to a pusher electromagnet 30 which opens the snap switch 28 to deprive the electromagnet 25 of current, thus allowing the slide valve 20 to return to the central position shown in the drawing in which position the chambers of the cylinder 4 are shut off from the supply pressure medium. The cylinder 4 holds the rail 1 in the lifted position and a packing-tool assembly consolidates ballast beneath the lifted rail and the sleeper. A switch 45 is now manually or automatically closed to energize a pusher electromagnet 26, from the battery 32, which pushes the valve 20 to the left into a position in which the lower chamber of the cylinder 4 is supplied with a pressure medium from the tank 16 to lift the bearing-plate 3 and to disengage the member 2 from beneath the rail 1. The switch 45 is now released to enable the valve 20 to return to the position shown in the drawing and the cylinder 4 is pivoted outwards by the cylinder 9 to enable the machine to travel to the next section of the track to be lifted.

A resistance thermometer comprises a platinum wire, constituting the measuring element, supported on the outer surface of a carrier tube, at least the outer surface of which tube consists of high temperature-resistant metal oxides, preferably sintered aluminium oxide. An outer sheath consisting of an insulating covering layer of a high temperatureresistant ceramic material is fused or sintered directly on to the platinum winding and the carrier tube. The carrier tube may be profiled or grooved. The interior of the tube may receive the current lead and may communicate through holes with the surface. The covering layer may consist of glass with a high softening- point, for example glass poor in alkali or rich in alkaline earth or alumina. The glass may be applied to the measuring winding in the form of fibres, twisted threads, glass tow, spun glass, or powder, and then heated to form a covering layer free from air gaps, or it may be applied by spraying. Alternatively the covering layer may consist of a ceramic material sintered or fritted on, such as pure aluminium oxide or aluminium oxide with a small addition of glass powder. In a modification, a metal tube forms the core of the carrier tube and is provided with an insulating covering layer on which the platinum winding is wound, a second covering layer preferably of the same kind then being applied. The carrier body may be formed from oxidation resistant metal compositions comparable in their thermal expansion to the covering layers, for example alloys of iron, nickel, and manganese, or of iron and chromium, in association with glassy covering layers.
