IPC: F16K31/363
Filed: 1973-09-14
Abstract: 1440208 Valves FnB PRODUCTS Inc 14 Sept 1973 [30 Oct 1972] 43371/73 Heading F2V In a valve, e.g. for use as a pressure regulator, fluid entering through inlet 36, Figs. 1 and 3, passes through radial ports 34 and thence into wedge-shaped annular space 31 to force valve member 44 away from its seating 28, whereby the fluid passes through passage 54 and hollow stem 56 to outlet 20. The member 44 is biased towards its seating by an assembly of spring washers 64, the biasing force being adjustable by a nut 62, the latter engaging the spring washers via a thrust washer 68 and a roller bearing 70. Fluid pressure may be admitted through a pipe 90 to additionally bias the member towards its seating. In Fig. 5 (not shown) the spring washers are omitted and the biasing is entirely by fluid pressure. Biasing may be provided by gravity, electromagnetic means, e.g. using repulsion or attraction effects of a solenoid (112), Fig. 7 (not shown), or manually via a lever (96), Figs. 6, 6A (not shown), which axially adjusts a sleeve (86) having one end in abutment with the spring washer assembly. Member 44 has seals 48 and has a third seal or a bearing member 52. In Fig. 9 the valve is arranged between inlet and outlet manifolds 130, 132 of a pump and returns excess pressure flow to the inlet manifold, the position of seating 158 being adjustable by rotation of shaft 172. The housing, seating, valve member and stem of a valve may be of stainless steel. Dimensions of the components of a valve are given in the Specification.

Apparatus for measuring displacement between two relatively movable members such as parts of a machine tool comprises a rotatable drum 27 mounted in a housing secured to a stationary part 56 first and second flexible elongate members 47 and 90 respectively one end of each being secured to the drum and the other end of each being secured to a movable part 57 of the machine, the second flexible member being tensioned by a spring 91 and each member being respectively windable and unwindable with respect to a helical track 49 on the drum when relative movement occurs between the drum housing and the part 57 of the machine, the angle of inclination of the first and second elongate members remaining constant and equal to the angle of the helical track. The rotation of the drum is transmitted, through gearing driven from the drum shaft 28, to calibrated dials 20, 21, 22 and the displacement between the parts is indicated on the dials by pointers 33, 39 and 42, respectively. The flexible members are enclosed by telescopic sheaths 50 connected between the housing and the mountings 51, 51a of the respective flexible members on the part 57 and the members are enclosed by the sheaths during all working conditions.

In a modification of the slow wave structure disclosed in the parent Specification, for use in travelling- wave amplifiers, backward wave oscillations, and particle accelerators, copper bands or metallized surfaces 3, supported on the inner peripheries of the beryllium oxide rings 2, are interrupted as at 4, adjacent bands being connected by copper bars 5, arranged such that the conductive path winds always in the same sense about the axis, to give a helix-derived structure of increased bandwidth. The beryllium oxide rings may themselves be either interrupted, as at 9, or recessed (Fig. 2, not shown) opposite the ring interruptions, to give increased helical coupling with a beam passing through the structure, and the rings may be provided with additional, smaller recesses (Fig. 3, not shown) to reduce the capacity further. In a further embodiment (Fig. 5, not shown) the connecting bars 5 make an oblique angle with the conductive annuli 3 which they connect, such that the structure approaches more closely the helical form. The beryllium oxide rings may be spaced apart by ceramic cylinders lining the metal envelope, and attenuation may be provide by coating some of them with carbon.

[Also in Division F2] In a process for the manufacture of conical and cylindro-conical tubes the developed surface ABDC of a frustum of a cone having an apex angle a which it is desired to reproduce is traced on a rectangular sheet of the desired material, e.g. metal or a plastics material, and the rectilinear sides AC and BD of the curvilinear trapezium are prolonged as far as their point of intersection S. A circle T 1  described about the triangle constituted by the point S and one of the bases of the trapezium ABDC and a circle T 2  of centre S extending through the two apices of the other base of the trapezium are plotted, and a point # is taken on the circle T 1  which point is joined to the two trapezium apices through which the circle T 1  passes. The two straight lines thus obtained intersect the circle T 2  at the points P, Q respectively, and a strip is cut along the curvilinear trapezium limited by the straight lines #P and #Q and the circles T 1 , T 2 . The strip is wound into the form of a pseudo-helix of continuously varying diameter, the strip forming with the axis of the helix an angle equal to radians, and the adjacent edges are joined together by means such as welding, brazing or clamping. The process is repeated until the whole of the rectangular sheet is used up. The strip 2 is fed between direction imparting rolls 24 having parallel axes and from a drum 3 mounted in a movable carriage so that the drum is displaced through an arc of a circle 30 and on a path inclined relatively to the axis 10. The device (1), Figs. 9 and 10 (not shown), for forming successive turns of the strip comprises a fixed cylinder (11) having a slot (12) for entry of the strip and provided with guiding means constituted by rods (13) extending through the cylinder into a housing (15) and guided by cams (16). The formed tubes (60), Fig. 11 (not shown), comprising two conical frusta are guided on a conveyer (40) by carriages (52)-(54) and cut along the lines (61), (62).
