Abstract: The vehicle frame is connected to bogie pin-less sets of travelling gear located below it via double-acting hydraulic cylinders (A, B, C, D) in such a way that preferably the cylinders (1) are coupled to the vehicle frame and the piston rods (2) are coupled to the sets of travelling gear. Each hydraulic cylinder (A, B, C, D) has a first working space (I) and a second working space (II). For the purpose of hydraulically coupling the turning-out movement of two sets of travelling gear and for simultaneous transmission of the traction forces and braking forces between the sets of travelling gear, in each case a first working space (I) of the hydraulic cylinders (A, B) of one side of the travelling gear is connected to the first working space (I) of the hydraulic cylinders (C, D) of the opposite side of the travelling gear by means of lines (8 and 9) whilst in each case a second working space (II) of the hydraulic cylinders (A, B) of one set of travelling gear is connected to the second working space (II) of the hydraulic cylinders (C, D) on the opposite side of the vehicle of the other set of travelling gear by means of lines (10 and 11). Open-loop and closed-loop control valves (13) and an elastic pressure accumulator (12) are expediently provided in the lines (8, 9, 10, 11) or in secondary lines. <IMAGE>

Title: Drive circuit for magnetic core data transfer device
IPC: H03K17/73
Filed: 1964-12-04
Abstract: 1,035,390. Circuits employing magnetic storage elements. AMP Inc. Dec. 4, 1964 [Dec. 20, 1963], No. 49311/64. Addition to 933,894. Headings H3B and H3T. In a shifting register using multiaperture cores as described in Specification 899,366, in which the information pattern is shifted by alternately pulsing two drive windings Lo, Le respectively associated with odd and even cores, the drive windings are energized alternately from a condenser 25 which is discharged through a winding when an associated solid state electric switch 11, 12 is rendered conductive, the condenser being prevented by a control circuit from fully recharging until the switch last rendered conductive becomes non-conducting. As shown, four layer diode switches 11, 12 are used which are alternately rendered conductive by trigger pulses applied through condensers 13, 16. The condenser is normally charged from a D.C. source 10 through a transistor 28 and a low resistance 29. When a switch 11, 12 is closed the condenser 25 discharges by way of a diode 24 and the transistor 28 is cut off. Since the discharge circuit of the' capacitor is inductive and comprises additional inductors Lc, Ls, an oscillatory condition is obtained and a small reverse current passes through the discharge circuit when condenser 25 is fully discharged. This small reverse current through diode 24 tends to charge the condenser in the opposite sense and maintains the transistor in the non-conductive state, the small reverse condenser voltage obtained being sufficient to cause the conductive four-layer diode to switch off. Until this occurs the condenser is slowly recharged towards normal sense through a high resistor 27. After the four layer diode is switched off then backward current is terminated by the diode and the transistor again becomes conductive. In a modification, Fig. 6 (not shown), silicon controlled rectifiers are used as the solid state switches, the control electrodes being grounded through resistors 34, 35.

Title: Method of joining tube coupling components made of cross-linked polymers
IPC: F16L13/14
Filed: 1974-11-19
Abstract: 1474929 Pipe couplings ATOMENERGI AB 19 Nov 1974 [27 Nov 1973] 50129/74 Heading F2G In a method of coupling a tube to another tube or to a wall, both tubes and wall consisting of cross-linked polymeric material, a tube end or an opening in the wall is deformed to a shape deviating from that formed when cross-linking the polymer so that one tube end can be inserted into the other one or into the opening to form a joint location, the latter being heated to a temperature where the deformed tube end or opening returns, as a consequence of a memory effect, to its shape at the time of cross-linking so that a joint is obtained, the heating being maintained for long enough to produce fusing together over the joint location. To provide stronger locking at the joint, the tube end to be inserted may have a metal ring 9 (Fig. 1b) assembled in it by deforming the tube end as above. Two tube ends may be coupled in a butt joint by using an external or internal sleeve, the sleeve being respectively expanded or shrunk prior to forming the joint location and heating: alternatively the tube ends may be shrunk or expanded respectively. A tube end of large diameter may be joined to one of small diameter by use of an intermediate sleeve. Side tubes may be joined directly to a main tube (Fig. 3a), the wall thickness of the latter being increased if desired by applying an external sleeve 19 as above. When joining tubes to walls, the opening may be stepped (Fig. 3c) and the tube end equipped with a sleeve 24 or with an internal metal ring. Suitable cross-linked polymers possessing the required memory effect are polyolefins such as polyethylene, polypropylene and polyisobutylene, and polyamides. To further improve joint strength, formed joints may be irradiated with high-energy radiation or the components may be coated with a crosslinking agent, e.g. dicumyl peroxide, prior to forming the joint location and heating.
