Title: Closed-circuit hydrostatic transmission and an axial piston machine for same
IPC: F04B23/10
Filed: 1975-08-19
Abstract: 1516116 Hydrostatic transmission control LINDE AG 19 Aug 1975 [20 Aug 1974] 34353/75 Heading F2W [Also in Division F1] In a hydrostatic transmission for a motor vehicle having a pump in closed circuit with a motor, the pump or motor is a tilting head unit 6 having a displacement variable between zero and a maximum and a reversing valve 21 or 165, 169, 170, 171 in the circuit between the pump and motor is provided in a base plate 12 of the unit housing 1. The unit 6 which is preferably a pump has a plate 10 secured to the end of its tilting head. The plate 10 has a cylindrical surface 11 which slides in a complementary recess in the base plate 12 and the plate 10 is connected by a rod 14 to the piston 29 of a follow-up servomotor that is housed in the base plate 12. A control valve 30 for the follow-up servomotor is connected by a linkage 31, 33, 44 and 62 to a manual control lever 60. In Figs. 3 and 4 the reversing valve comprises an axially slidable valve spool 21 which is biased by springs to a central position in which it blocks flow between the pump and motor. Alternatively the valve 21 may interconnect the pump lines in its central position. The valve spool 21 is moved to one or other of its end positions for forward or reverse drive by pressure liquid supplied through a valve 38 to one or other of its ends. The valve 38 is controlled by the lever 60. The lever 60 preferably actuates the valve 38 prior to actuation of the follow-up servomotor. In Fig. 11 the reversing valve comprises fluid pressure actuated valves 165, 169, 170, 171 which selectively connect pump lines 167, 168 with motor lines 163, 164. A control valve 138 selectively supplies pressure liquid to the valves 165, 169, 170, 171 to open valves 165, 170 or valves 168, 171 for forward or reverse drive. A shuttle valve 175 connects the motor line at the higher pressure to an override valve 178. When the motor supply pressure exceeds a predetermined value the valve spool 178 is moved left and connects the control pressure line 182 to exhaust at 183 whereupon all the valves 165, 169, 170, 171 open to provide a by-pass between the pump delivery and return lines. The override valve 178 may be actuated manually by a screw 189 to permit towing of the vehicle. In Fig. 13 (not shown) the shuttle valve (185) additionally supplies make-up liquid to the low pressure motor line.

Abstract: 1481324 Making electrical contacts E I DU PONT DE NEMOURS & CO 6 Aug 1974 [9 Aug 1973] 34626/74 Heading B3A A method of attaching a metal element, W to form, e.g. an electrical contact C, to a metal member or strip S comprises, engaging an end portion of the element W with the member S, welding the member to the element thereby heating the element and removing heat from the element to establish a difference in temper along a boundary (B), Fig. 6 (not shown), adjacent the weld region and pulling the element to break it away from the member along the boundary leaving the end portion still attached. The strip S is fed intermittently over a welding electrode 17 and the element W, which is preferably a hard gold wire, is fed to an electrode 19 having opposing jaws. The electrode jaws are closed on the wire by a clamp 21 and an air cylinder 21 is activated to pivot the electrode 19 downwardly about trunnions 23. The strip is urged against the electrode 17 as the end of the wire is flattened and welded to the strip. The temper boundary (B) is established by the weld heat and by the removal of heat from the wire by the jaws. The clamp 21 is released, the jaws withdrawn approximately to the boundary (B) and the clamp reactivated. The electrode 19 is then withdrawn and the wire breaks along the temper boundary to form the contact C, which may be finally shaped by a coining member 25 and anvil 26. The method may also be used in the manufacture of gold plated electrical sockets.

Abstract: 448,333. Indicating-apparatus. ELECTROFLO METERS CO., Ltd., and ENGEL, F. V. A. E., Abbey Road, Park Royal, London. Dec. 3, 1934, No. 34710. Drawings to Specification. [Class 106 (iv)] Apparatus for measuring the flow of liquids in open channels comprises two members each independently displaceable with variations in functions which vary with the liquid flow, the movements being combined to give a result dependent on the rate of liquid flow, wherein the first member is moved along a rectilinear path and the second moves along a path transverse thereto, and is coupled to a lever, the result being determined by the position relative to the rectilinear path of a third member slidably engaging both the lever and the first member and constrained to follow the path of the point of intersection of the lever and a line parallel with the transverse path and passing through the first member. One of the members may be moved proportionally to the square root of the difference of head between a point on the upstream side of a Venturi flume and a point at the throat of the flume, while the other member is moved proportionally to the head at one of these points. The embodiment described is the same as the device shown in Figs. 1 and 2 of Specification 448,332 and described in that Specification. Specification 409,218, [Group XXXVI], also is referred to.

Abstract: 1,058,064. Transformers; insulation. LICENTIA PATENT-VERWALTUNGSG.m.b.H. Sept. 3, 1963 [Sept. 3, 1962], No. 34831/63. Headings H1A and H1T. A method of making a cylindrical insulating member having a peripheral end flange comprises the steps of making incisions in laminar insulating material composed of at least three superimposed layers 12, 13, 14, winding the incised layers on to a primary winding body to form a cylinder of the material, and turning over one axial end to form the end flange, the incisions being so situated and orientated as after winding to extend longitudinally of the cylinder at the turning over position in such a manner as to permit the turning over, and the winding operation being effective to displace the incisions in each of the two outer ones of said superimposed layers relatively to those in the adjacent intermediate layer or layers so as not to be coincident therewith after winding. In one method, the incisions are made on a secondary winding body. The layers are then re-wound on to the primary winding body in such a way as to mutually displace the incisions of adjacent layers. In another method, the layers are simultaneously incised before they are wound on to the primary winding body in which case the layers are off-set as required before they reach the winding body. The insulating material when made into " angle ring " insulation may have wedge-shaped incisions. Such angle rings may be used to insulate the windings of a transformer (Fig. 6, not shown).

The command criterion may also constitute a "call criterion" or alternatively it may be transmitted prior to a "call criterion". When a multi-slot connection is no longer required a special connection clearing signal is transmitted to the exchange. The Specification discusses various binary codings for the command and clearing signals in dependence on the number of slots to be combined and the type of transmission (transparent or non-transparent) to be used.
