Abstract: 1,215,700. Valves. M. R. LENTS, J. R. BUTLER, M. G. MILLER, J. B. ATKINS, J. B. SAUNDERS, JNR. and K. B. FORD, [trading as J. R. BUTLER and E. E. HULSEY]. 27 Dec., 1967, No. 58695/67. Heading F2V. In a rotatable plug valve, the axis of rotation a-a of the plug is arranged at an acute angle X to the axis b-b of a maximum throughflow passing 21 which is alignable with inlet and outlet passages (20-20) if a valve body (10), Figs. 1-3 (not shown). In addition, elongated slots 22 are formed in the plug at spaced positions corresponding to the ends of the passage 21. The traces of these slots on the plug surface taper as shown in the circumferential direction, whilst their walls are inclined at an angle Y to the rotational axis which is preferably equal to the angle X. By this arrangement, the flow is variable down to a minimum whilst maintaining substantially straight line flow throughout. Blind portions 25 between the ends of the slots are provided with sealing 0-rings in recesses 27. An additional 0-ring is housed in a recess 29. In a modification, about half of the plug is removed at a plane just on one side of the recess 29. The invention is also applied to conical and spherical plug valves, Figs. 13-17 (not shown).

[Class 39 (i)] [Also in Group XXIV] The positive carbon P is fed forward continuously by an electric motor 22 which is kept, by a mechanical or electrical governor 23, at a constant speed calculated to give a feeding rate to the carbon equal to its predetermined burning rate. The motor drives a train of gears 21, 26, 27, 28, 31, the two last being connected to shafts 30, 33, of which 30 rotates the carbon through bevel gears 17, while 33 feeds it forward through scroll gear 13 and spur gears 7, 8, gripping the carbon by spring pressure. The negative carbon is also fed forward by the motor at its predetermined burning rate, but intermittently through a friction ratchet clutch 40 actuated by a lever (not shown) moved by a cam 41 on shaft 33. The clutch engages feed shaft 39 only on its forward travel (see Group XXIV). Handle 75 enables the negative carbon carriage to be brought forward for striking; an electromagnet 76 may also be used for striking. Specification 450,908 is referred to.

Patent GB-2015454-A (GB)
Title: Spherical Vehicle to be Self- Propelled in a Fluid Medium
IPC: B64C39/00
Filed: 1979-02-05
Abstract: A spherical vehicle for operation in a fluid medium utilizes an impeller 12 of approximately half the diameter of the sphere for propulsion. In addition to providing the energy for driving the sphere, the impeller acts to draw the flow of fluid smoothly over the after part of the sphere, thus avoiding or minimizing the tendency of the flow to separate from the surface of the sphere and create turbulence. Steering in pitch and yaw planes is effected through the use of a plurality of drag pins 18 located just behind the circle of maximum diameter (with respect to the direction of motion) and selectively actuated by a guidance or control system. A plurality of stub vortex generators 14 are also located on the after side of the sphere and are angled to oppose the torque created by the propeller. The general configuration applies to a powered under-water vehicle or to a lighter- than-air vehicle traveling through air, or to a manned submarine vehicle having the usual propulsion means. <IMAGE>

Filed: 1979-07-11
Abstract: The invention relates to a method and assembly for providing a corrosion resistant lining in a passageway, particularly a manhole, to prevent deterioration due to corrosion of the conventional concrete lining. A flexible sheet 22 of a polyester glass composite is stiffened for example by means of corrugations and is formed into a cylindrical configuration to be received at its ends in open ended slots 20 formed in rigid end flanges 10, 12. The sheet is fastened to the flanges by plugs 24 and the assembly is then used as an insitu mould surface for cementitious material used to form a passageway. Passageways such as manholes of different heights can be aligned by connecting one or more of the flexible sheets endwise together. Storage and transport are greatly facilitated when the flanges are provided in sections as the flexible sheet can be stored and transported in a flat condition. <IMAGE>

Title: Casting tool blanks
IPC: B22C9/00
Filed: 1979-08-17
Abstract: A feederless casting process, applicable to making blanks for subsequent formation by dimension reduction into edged tools, uses a sandwich type mould of which a central part (11) is a plate with a profiled slot (12). The slot is oversize compared to the desired casting (15) and is infilled with readily deformable material (20) such as sand. The mould part 11 is permanent and repeatedly usable whereas the sand core 20 is temporary and can be crushed by shrinkage of the cast material as it cools. In this way, casting is facilitated for complex shapes that would tend to grip parts of the slot as they shrank on cooling. <IMAGE>
