Abstract: 407,333. Implements and machines for working land. WALKER, A. W., The Elms, West Halton, Scunthorpe, Lincolnshire. Sept. 14, 1932, No. 18018. [Class 6 (i).] A harrow comprises a series of fixed tines and a series of tines mounted at short distances apart and moved in parallel lines across substantially the same strip of ground and transversely to the line of movement of the machine, so that in harrowing a field in one direction the same effect is obtained as if the field were harrowed with an ordinary harrow first in one direction and then in a direction transverse thereto. The rectangular frame 1 shown is mounted on two travelling wheels 2 each of which drives an inclined shaft 7 through the chain and bevel gearing shown. The parallel shafts 7 drive independent sets of parallel endless chains 10 bychain gearing 11, 12, 13. The chains 10 are carried by hexagonal chain wheels 16, 18 provided with guides and mounted on shafts 68, 14 supported in inclined frame bars 15. The lower parts of the chains run in channel-shaped guides. The wheels 2 are mounted in frames 36 which may be simultaneously raised between guides by screw mechanism driven by bevel and worm gearing from a shaft turned by a hand crank. By means of the same hand crank and similar screw mechanism castor wheels for transport purposes may be lowered as the wheels 2 are raised. Draught hooks may be provided at the end of the frame 1 so that it may be drawn endwise on the castor wheels. The tines 20, Fig. 5, may be fixed on the chain links 19, or pivoted on pins 40 and controlled by flat springs 41 bearing on projections 46, 47 and protected by guards 44.

Title: Improvements in or relating to methods of making supported films and films made by such methods
IPC: B05D7/26
Filed: 1961-05-19
Abstract: A supported film of organic electrical insulating material which can readily be stripped from its support is obtained by depositing or joining a layer of the material on to a carrier the surface of which has been previously impregnated or coated with a mixture consisting of or including at least one hydrocarbon having a melting point of at least 60 DEG C. and a high molecular weight organic polymer adhesive. The preferred mixture is 40% polyethylene or polypropylene having a molecular weight of approximately 1,000-3,000 and a melting point of approximately 105 DEG C., 48% of a wax having a melting point of approximately 110 DEG C., and 12% of polybutylene having a molecular weight of approximately 1,000 to 3,000.  In examples, a carrier in the form p  of a paper bond is impregnated with the mixture and then the roll unwound and heated and passed through smoothing rolls. Then, either a previously formed film of cellulose acetate of 4m thickness or a lacquer of cellulose acetate, benzyl cellulose, polystyrene, polytetrafluoroethylene or polyethylene terephthalate in a solvent is deposited on the carrier and the solvent removed to leave a film, and finally a coating of aluminium deposited in vacuo on the film.  The supported film may be used in the production of electrical condensers.  Specification 803,173 is referred to.

Title: Improvements in or relating to valves for fluids under pressure
IPC: F16K15/14
Filed: 1958-06-09
Abstract: 875,034. Valves. REGIE NATIONAL DE USINES RENAULT. June 9, 1958 [July 1, 1957], No. 18392/58. Addition to 846,271. Class 135. A valve controlling the supply and exhaust of pressure fluid to and from a pneumatically operated apparatus comprises a two-part valve body 1, 3, Fig. 2, having connections-2, 4 to a distributer valve and the apparatus respectively and a valve member slidable in the body comprising a resilient cup-shaped member 12 mounted on a rigid hollow support member 25. The resilient valve member is formed with a central orifice in its bottom surrounded by a flexible lip 19 and the support member with ports 26. On the actuation of the distributer valve to supply pressure fluid to the valve, the valve member moves rightwardly so that a peripheral bead 30 first closes exhaust ports 31 through the end of the body part 3. Pressure fluid in the hollow support member then moves the lip 19 away from the support member whence pressure fluid passes to the apparatus. On the distributer then being actuated to stop the supply of pressure fluid, the pressure of the fluid in the apparatus first seats the lip 19 to close the ports 25 and then moves the valve member to uncover the exhaust ports 31. A restricted port 33 covered by a resilient disc 34 may be fitted to permit rapid exhaustion of the valve body chamber and a quicker response to leftward movement of the valve member. The ports 31 are protected against the ingress of foreign matter by a flexible gasket 32. In a modification, a resilient check valve 42, Fig. 3, is fitted on the upstream side of the valve member in a three-part valve body. On the distributer valve being actuated to stop the supply of pressure fluid, the check valve 42 immediately closes and any pressure fluid in the valve body is exhausted through the restricted port 33.

Abstract: 1,179,844. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 9 May, 1967 [27 April, 1966], No. 18532/66. Heading G6C. A fuel element comprises a cluster of sheathed fuelrods secured at one end to a support grid bearing the weight of the fuel rods, spring means being provided on the support grid to releasably engage with an end portion of each fuel rod. As shown in Fig. 1, the support grid has a cell 3 for each fuel rod 2, each cell 3 being constituted by a tubular portion 4 having at its lower end an inwardly extending skirt portion 5 divided by four vertical slots 6. The cell 3 is made from an inherently springy material such as cold worked stainless steel. Each fuel rod 2 has circumferential or helical ribs 8 integral with, or secured by welding or brazing to, the sheath 7. A pellet 14 of heat insulating material, e.g. alumina, is disposed between the uppermost fuel pellet 9 and an end cap 15. The end cap 15 is end-welded at 16 to the upper edge of the sheath and preferably also seam-welded (not shown). The fuel rod 2 is fitted to the support grid 1 by axial insertion into the cell 3 from above. The tubular portion 4 embraces a plain cylindrical portion 11 of the upper end of the sheath 7, and the upper edge of the portion 4 abuts the lower edge of a flange 10. In moving to this position, the skirt portion 5 is forced outwardly against its springiness by the taper 13 on the upper end portion of the fuel rod. As soon as the bottom edge of the skirt portion 5 reaches the recess 12, it springs into this recess and abuts the shoulder 17 formed by the lower end of the recess.
