Title: Improvements in and relating to elastic fluid turbine rotors and method of making same
IPC: F01D5/04
Filed: 1920-10-19
Abstract: 174,181. British Thomson - Houston Co., Ltd., (General Electric Co.). Oct. 19, 1920. Turbines.-Turbine blades are first temporarily assembled in their final positions in the rotor, and the bladed rotor is then placed in a furnace and alloyunited by the process described in Specification 158,565. The blade-carrying element may be a solid ring, or it may be made up of a spirally wound ribbon or a number of thin discs alloy-united together. The 'blades 25 are upset at the ends to provide flanges 28 and spaced projections 27 which fit tightly into holes 26 in the blade-carrying rings 20 for the purpose of anchoring them in position during the alloy-uniting process. This process is carried out by placing the blade-ring structure in a furnace 29, Fig. 11, where it is pressed down on a bed of sand or asbestos by a weight 34 or other means operating through a light coating of sand or asbestos 35. A reducing gas, such as hydrogen, is admitted by a pipe 30 and discharged through a pipe 31, and a temperature of 1140‹-1150‹ C. is maintained, a suitable amount of copper or other alloying material being provided at desired points. Thus, copper wires 36, Fig. 10, may circle the structure, or bits of copper may be placed in the holes 26. Such holes may be provided in both rings and blades, locking pins engaging therein. The blades 49, Fig. 13, in Curtis turbines may be secured to the rim 46 by a similar process. Large blade-rings for radial-flow turbines may be builtup of rings 56, Fig. 15, of individual blades 55, secured as described above, and connecting-rings 58.

Title: Rotary plug valve
IPC: F16K5/18
Filed: 1965-07-12
Abstract: 1,040,515. Valves. MUELLER CO. July 12, 1965 [April 20, 1965], No. 29539/65. Heading F2V. A plug-cock has a body 12 with opposed inlet and outlet ports 16, 18, Fig. 1, and an intermediate drain port, whilst the rotary closure member 22 is hollow and provided with opposed opening 26, 27 and a drain opening 30. When the member is turned to close the inlet port 16 the openings 27, 30 are aligned with drain and outlet ports, respectively. An endless seal is arranged in a peripheral groove of the closure member between the openings 26, 27 and opposite the opening 30 to co-operate with the inlet port when the drain port is open and vice versa. The closure member 22 embodies a non- circular head 38 at one end for hand or wrench operation whilst the opposite end is formed with an annular flat bearing surface 40; opposed baffles 46 are located within the closure member. The body and closure member may be of synthetic plastics material. The drain port and opening may be omitted. In a modification, the main ports 66, 68 (Fig. 5, not shown) and openings 92 are elongated in the axial direction of the cock whilst a plastics element 86, pinned into the open-ended closure member, defines a fluid passage between the openings 92 to ensure a turbulence-free flow. The closure member is held in place by a split ring 115 overlying a tapered nylon thrust washer 110. As the closure member moves from closed to open positions the ports overlap so that line pressure momentarily passes to the drain port 116 for cleaning purposes; concomitantly line pressure passes through the drain opening 122 in the member 86 into a groove 124 to ensure equalisation of pressure on the inside and outside of the member 86 to prevent bursting thereof. The lower ends of the body and closure member are of reduced diameter and provided with flat surfaces and lugs, respectively, which define the limits of rotational movement and ensure proper assembly of the cock; the lower end face of the closure member is subject to line pressure when the valve is open. In a modification, the plastics element is retained within the closure member by a flange instead of a pin, and a lug on the lower end of the closure member coacts with surfaces in the body to define the open and closed positions of the cock.

Title: Improvements in vertical sliding shuttering
IPC: B61G5/10
Filed: 1948-11-15
Abstract: 660,815. Casting in situ. HEIDENSTAM, E. J. VON. Nov. 15, 1948 [Nov. 24. 1947], No. 29641/48. Class 20(ii) Apparatus having vertically sliding shuttering 9, 10, Figs. 3, 4, for the casting in situ of circular or other space enclosing concrete walls, silos &c. comprises a working platform 16 jointed with the shuttering so as to remain horizontal during continuous or intermittent lifting by climb fasteners or jacks 13 moving up irons 14 positioned in the wall space. The platform is so jointed with the shuttering and lifted, that the poured concrete is not subjected to horizontal shearing forces. The platform 16 is lifted on a framework comprising a central column 20 and struts 21, and the shuttering is lifted by forks 17, 19, positioned as shown, which forks engage bearing pins 18 of yokes 11 arranged around the periphery. The yokes also maintain the distance between the shuttering 9. 10, and hold the sections of the shuttering together at the top. The forks 17, Fig. 5, are connected to yokes attached to the climb fasteners 13, whilst the forks 19, Fig. 6, (not shown), have their bearing pins engaging cavities turned upwardly and are connected to yokes not directly supported by fasteners. In this manner the lifting force is evenly distributed to the shuttering. By employing pins 18 positioned outside the shuttering 9, and by using forks 17, Fig. 9 (not shown), the line connecting two adjacent joints or pins may be moved slightly outwardly of the medial line of the wall. The same effect may be attained by arranging the climbing irons of the shuttering 9 in bulges 25, Fig. 10 (not shown). A concrete distributer 28, Fig. 3, is fed from a skip 31 by means of a hoist. In casting rectangular enclosing walls, Figs. 12, 13, outer and inner shuttering 34, 35, is supported by equally spaced yokes and forks, and the plane metal sheets forming the shuttering are stiffened by angle irons 41, 42, both in the vertical and horizontal directions, two such adjacent irons 41 depending freely at the corners from a joining bolt 43 in order that the shuttering in oblique position will not damage the casting. A similar arrangement is provided for the inner shuttering. The shuttering 34, 35, may, however, be interconnected by springs at their lower corners. In the Specification as open to inspection, under Sect. 91, Figs. 11-13 (Cancelled, not shown) a construction of yoke is shown and described having legs the upper parts of which are of square tubular cross section, and the lower parts of angle section. In casting rectangular walls a yoke as shown in Fig. 15 (Cancelled, not shown) may be used. This subject-matter does not appear in the Specification as accepted.

Abstract: 385,390. Hydraulic shock-absorbers. RIPPINGILLE, F. S., 55, Hagley Road, Edgbaston, Birmingham. Oct. 29, 1931, No. 29958. [Class 108 (iii).] In apparatus in which a piston works in a double ended cylinder formed with an intermediate reservoir and in which the two end compression chambers are connected to the reservoir through one-way valves in the piston and are connected to one another through a valve-controlled passage, the piston is retarded during the entire length of stroke in one direction, but has a substantially free movement in the opposite direction until it approaches the end of its stroke when the movement is progressively cushioned. Figs. 1 and 3 represent vertical and horizontal sections respectively. The piston 2 is reciprocated in the cylinder by a depending arm 13 fixed in the operating spindle 6 and working in a slot in a pin 11 bearing at its two ends in the piston. The left hand compression chamber is replenished as required from the central reservoir through a passage 34 in the piston the end of which is uncovered by the disc valve 32 when the piston moves to the right. The two ends of the cylinders are connected by a longitudinal passage 20 in the casing, the flow through which may be regulated by an adjustable cock 21. The ends of the cylinder are further connected by a series of passages controlled by the one-way valve 32. Two or more passages 31 lead into a transverse conduit 30 which is connected to a similar transverse conduit 28 by passages formed by flats 29 on the sides of the piston. The transverse conduit 28 communicates with the right end of the cylinder by a passage 26 into which a tapered projection 27 on the cylinder cover enters when the piston approaches that end of the cylinder, so that a progressive throttling action is obtained. The arm 13 is forced into the hole in the spindle 6 after the latter is in position, an opening, which may be closed by a screw plug 16, being provided in the top of the reservoir for this purpose. The arm is further locked in position by a plug screwed axially into the spindle 6 and engaging the groove 19.
