Title: Pipe system comprising at least two coaxial pipes
IPC: F16L59/13
Filed: 1972-06-02
Abstract: 1350541 Multiple conduits KABEL-UND METALLWERKE GUTEHOFFNUNGSHUTTE AG 2 June 1972 [15 June 1971 20 July 1971] 25907/72 Headings H1A and A4D A coaxially arranged multiple conduit has the inner pipe supported within an outer pipe by spacers, each spacer comprising two or more ring segments, the cut away portions of each ring segment being large enough to admit the inner pipe and the ring segments being arranged one behind the other in the axial direction in closely spaced relation with the cut-out portions mutually angularly displaced, the outer periphery of the inner pipe being engaged by a plurality of threads, bands or wires attached to the spacer in such manner that each thread, band or wire engages the inner pipe. As shown in Fig 3, there are three identical ring segments 11 pivotally interconnected by a pin 16 parallel with the segment axes. Each segment bears a filament or the like 15 which engages the pipe 17 when the outer ring segments are rotated to overlap the central segment. Pins 18, 19 are then inserted to lock the spacer. The pins 16, 18, 19 also bear on the outer pipe. Alternatively (Fig. 5), a major ring segment 20 and a minor ring segment 27 may be pivotally interconnected at 29, the major segment bearing two filaments 24, 25, and the minor segment bearing one filament 31. The pin 33 serves only as a bearer for the outer pipe. In a further alternative (Fig. 7), each leg of a major ring segment 36 has a minor ring segment 37, 38 pivoted thereto. The major segment 36 bears a filament 41 and one end of each filament 42, 43. The filaments 42, 43 are folded round the inner pipe when the segments 37, 38 are rotated to overlap segment 36. Pins 46, 47 lock the spacer and all three pins 46, 47, 48 bear against the outer pipe. The constituent ring segments of a spacer need not be hingedly interconnected but may be separately located and then locked with pins. Bolts may be used instead of pins if desired. Short axially aligned bars may be secured to the outer peripheries of the ring segments to bear against the outer pipe if bolts are used. The pipe is particularly useful for heat insulating purposes as the filaments, which may be threads, bands or wires and which may be of synthetic resin (e.g. prestretched polyester or nylon) or of metal, afford very little conduction of heat and present low resistance to flow of fluid in the outer pipe. Liquid hydrogen or helium may be conducted through the inner pipe and the interspace evacuated and filled with insulant (e.g. laminated metal foils or metallized synthetic resin films with interposed layers of glass fibre fleece or fabric). The inner and outer pipes may be of copper or stainless steel and may be helically or circumferentially corrugated. If the inner pipe is circumferentially corrugated the support filaments may be engaged in a trough of the corrugations. A sheath of thermoplastics material may cover the outer pipe. Low temperature of super-conductive conductors may be placed in the inner pipe, or alternatively a high temperature fluid may flow therein.

Abstract: 718,754. Fluid-pressure brakes. BENDIX AVIATION CORPORATION. Oct. 17, 1952 [Oct. 17, 1951], No. 26129/52. Class 103(1) In a fluid-pressure servo-device of the type described in Specification 702,554, the diaphragm 58 which operates to transmit " feel '' to the operator through button 114 is of such a construction that it provides an initial low pressure reaction right from the first movement of the pedal followed by a further reaction at a higher pressure range after the brake shoe clearance has been taken up. This form of operation is provided by constructing the diaphragm with two concentric rigid portions 102 and 104 interconnected by means of a flexible member 106. When the control valve is operated to actuate the device, evacuation of air from chamber 50 and simultaneously from chamber 56 to the left of the diaphragm at first causes only the centre part 102 and flexible member 106 to move to the left due to the force of spring 118 holding the outer part 104 to the right. At a later stage the force of the spring 118 is overcome whereupon the entire reaction member moves to the left.
