Title: Improvements in or relating to four-wheeled railway vehicles
IPC: B61F5/32
Filed: 1969-05-12
Abstract: In a railway vehicle having two wheel-sets mounted on the vehicle frame 4, each wheel-set is mounted on the body through a suspension comprising multistage vertical springing having different spring rates for different loadings, swing-links 8 having low lateral stiffness, longitudinal traction rods 17 and hydraulic dampers 24, 25 damping vertical, lateral, and roll motions. Each wheel 1 of the wheel-set is mounted on a line axle rotatably mounted in axle boxes 3. In one embodiment (Figs. 2 and 4) the vertical spring comprises, on each side of the vehicle, nests of coil springs 13, 14 supported on base members 12 in turn supported on knife edge members 10 slidably mounted on the swing links 8. The swing links 8 are suspended, by way of knife edge members 6 and rubber pads 7, from a longitudinal beam 5 secured to the axle box 3, the knife edge members 6 supporting T-shaped upper ends 9 of the links 8 to permit longitudinal movement between the wheel-set and the frame 4. The knife edge members 10 are adjustable, longitudinally of the links 8, by way of nuts 15 for equalization of wheel loads. Each spring 13 engages at its upper end a bracket 16 on the frame 4, but each spring 14, which is shorter, does not engage this bracket 16 until the vehicle is part loaded. Each traction rod 17 is attached to an axle box 3 via spherical mounting including a spherical rubber bush (20, Fig. 3, not shown) of low torsional and conical stiffness and high radial stiffness, and extends towards the transverse centre line of the vehicle for attachment to a bracket 19 via a differential rubber spring 23 of low conical stiffness and the required axial stiffness. In a second embodiment (Fig. 7) the vertical spring comprises, on each side of the vehicle, tapered leaf springs 40 and coil springs 48. The leaf springs are mounted on the axle box 3 and support at their free ends knife edge members 6, 7 at right angles to one another. The swing links 8 hang from the knife edge members 6 and slidably support knife edge members 10 supporting base members 12. Each base member 12 supports a rubber unit 46 mounting a plate 47 which supports the coil spring 48. The upper end of the coil spring 48 abuts a platform 49 at the lower end of frame-brackets 50, a spigot 51 depending from the platform 49, so that on partial loading of the vehicle this spigot 51 abuts the plate 47 to render the coil spring 48 ineffective. The traction rods 17 are again attached to the axle boxes via spherical mountings, and the other ends of the rods 17 are attached to a plate 54 connected to the frame via a member 55 and a bracket 50. The plate 54 is sandwiched between a series of rubber dies 53 compressed between end plates 56 secured to the rod 17, the compression of the discs 53 being adjustable by a nut 17.

Title: New texturised yarn
IPC: D02G1/02
Filed: 1969-11-22
Abstract: A yarn comprises as the sole constituents 1 to 5 thermoplastic continuous filaments of gauge above 5 dtex and having a spiral crimp and/or residual twist torque, each filament having a cross-section which is essentially oval except that one side is concave or substantially flat, and which varies slightly along the length of the filament. The filaments are preferably of polyamide or polyester material. The process for making the yarn comprises the steps of heating a twisted yarn, which has been obtained by giving an initial doubling or assembling twist to two or more synthetic thermoplastic continuous filaments 1 of gauge above 5 dtex, or to two or more yarns 17, 18 each comprising 2-5 such filaments, to a temperature permitting setting and deformation of the filaments without causing individual filaments to stick together, blocking the twist at a definite point i.e. feed rolls 4 or 28, separating the individual filaments or yarns at a point close to where they leave the heating zone, cooling the separated filaments or yarns, and winding them up. The filaments or yarns may be stretched prior to being twisted, and the point of draw may be localised by a snubbing pin 26. The degree of stretch and/or the degree of twist may be varied with time. The separated filaments or yarns may be relaxed with the accompaniment of heat. The apparatus may be arranged such that either a single filament or yarn is supplied from a package by over end yarn feed, or one or more filaments or yarns are supplied from a package 2 by unrolling, or two filaments or yarns are supplied by over end yarn feed in opposite directions as from packages 19, 20. In the case of a single filament or yarn being supplied over end means are also provided for controlling the degree of twist to compensate for the twist imparted by such feed. Such means may comprise a movable spindle having at least two arms arranged symmetrically about the spindle and provided at their free ends with a passage for the yarn, the spindle being provided with means e.g. a magnetic element, for exerting a return torque in opposition to the twist torque. The spindle is driven by a drum from a motor. The separating means preferably comprises a hollow spindle having at its upper end at least one mandrel integral with the internal wall of the spindle and having a free end over which the filaments or yarns are passed. The spindle rotates in a fixed sleeve.

Patent ES-470329-A1 (ES)
Title: Vector generator
IPC: G09G1/08
Filed: 1978-05-30
Abstract: A vector generator having a digital input and a cathode ray tube (CRT) display output is disclosed. Digital values specifying the initial point of the line segment in Cartesian coordinates are converted to proportional voltages applied across the capacitors of two identical resistance-capacitance networks which control the positioning of the CRT beam. A second pair of digital values defining the length and direction of the line segment with respect to the initial point are normalized digitally by left shifts until the larger of the pair equals or exceeds a normalization constant. The normalized values are added to the initial point coordinates, and the sums are then converted to proportional voltages applied to the resistors of the two networks. Simultaneously, a timer preset during the normalization operation is started and the CRT beam is turned on to start the drawing of the line segment. As a result of the normalization, the voltages applied to the RC networks are larger than needed to draw the segment. Consequently, the beam will be turned off by the timer well before the outputs of the RC networks reach the applied voltages. Thus, line segments of widely differing lengths are drawn at a normalized fast rate and are displayed at a normalized uniform visual intensity on the CRT.
