Title: Improvements in or relating to nuclear reactors
IPC: G21C3/33
Filed: 1965-04-13
Abstract: 1,091,155. Fuel elements. BABCOCK & WILCOX CO. April 13, 1965 [April 13, 1964], No. 15629/65. Heading G6C. A container for an assembly of nuclear fuel elements has its walls provided with longitudinally extending cavities. Each wall may be formed by a plurality of tubular members extending side by side and each sealed to the next along its length, or each wall may be formed by an outer layer, an inner layer spaced from the outer layer, and struts connecting the two layers together. The struts may be in the form of webs separating discrete passageways extending along the length of each wall, and in one embodiment are provided by a corrugated layer extending between the outer and inner layers with its crests connected to these layers. Some, at least, of the cavities may each contain a fuel element and provide flow paths through which coolant flows over the elements. The container may, for example, be hexagonal in cross-section so that when it is disposed within the reactor core it will have pairs of opposed side walls of which one is nearer to the core axis than the other. By arranging for the concentration of nuclear fuel in the fuel elements to be lower, or for the fuel elements to be of smaller cross-section, in the wall nearer the core axis, the thermal expansion of the opposed walls can be equalized.

Filed: 1927-06-13
Abstract: 272,552. L'Orange, P. June 12, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Regulating.-In aircraft engines designed to work under normal conditions at high altitudes, the cylinder pressure is reduced automatically when the machine descends to lower altitudes by means of a pressure gauge, such as a membrane Bourdon tube, or a piston, which may be actuated by atmospheric pressure, or by pressure tapped from the engine cylinder at a given point of the working stroke. Fig. 3 shows a piston L working in a cylinder E and controlling the admission cam N, the piston L being subjected, against the action of a spring F, to pressure tapped from a point 0 in the engine cylinder. The port 0 is fitted with a check valve y, the spring of which is strong enough to resist the normal working pressure, and an adjustable leak Y is provided on the cylinder E. In another form, a membrane, subjected on one side to atmospheric pressure and on the other side to a constant pressure, is connected to the throttle valve. In engines designed to work under normal conditions at lower altitudes, the pressure device may control the charging-pump.

Title: An improved lathe attachment for facilitating successive cutting operations such as the cutting of screw threads
IPC: B23G1/02
Filed: 1919-06-24
Abstract: 144,111. Godfrey, A. June 24, 1919. Tools; tool-holders; turning. - A lathe attachment for use in successive cutting operations has means whereby, after the desired length of work has been cut, the tool is automatically disengaged from the work, and is restored by hand to the cutting position at the beginning of the next cut, the restoration simultaneously putting on the desired depth of cut. The attachment 2 carries a sliding member 3 to which the tool 20 and toolholder 27 are pivoted, the member 3 being screwoperated to cause feeding of the tool. The total amount of feed is set by a micrometer 15, 16, and a stop 17 to coact with a fixed stop, and the amount of feed at each cut is regulated by fixed 'stops in holes 12 contacting with an adjustable stop 13 in the frame 11 which actuates the ratchetwheel, Fig. 4. The micrometer is temporarily fixed while making adjustments by the pawl 41 actuated by an eccentric pin 42. The tool 20 has a number of cutting-edges which may be used in succession, and is held against rotation by a stop 22 slidably connected to the holder 27; this holder is held by a catch 29 against spring action 28. The release of the catch by a fixed stop on the machine causes the holder 27 to be pressed upwards and to oscillate the cutting-edge of the tool from the work. A pivoted handle 33 serves to reset the cutter and at the same time to operate the ratchet feeding device. After regrinding, the tool can be reset for correct cutting by an eccentric pin and slide arrangement causing slight motion of the carrier 2 on the machine slide 1. The tool stop may comprise a sliding rectangular plate adapted to engage a cutting-edge of one tooth of the cutter and a shaped back edge of an adjacent tooth. The ratchet feed may also be directly operated by a handle on the pawl link, and the stop-holes for regulating the amount of feed formed in staggered relationship to enable a finer adjustment to be made. In a modification, Figs. 7 and 8, the tool 66 is clamped to a pivoted holder 65 actuated by a lock spring to release the tool when the catch 71 is released; the holder is carried by a member 58 attached to a rotatably adjustable support 54 mounted on a cross-slide 60 which slides in another member 51 slidably mounted on a rotary support on the lathe sliderest. In this modification, the stop on the machine is made adjustable in position to regulate the position of release of the cutter, and a fine and coarse adjustment of the pivoted catch by an eccentric pin is possible. In a further modification, the tool-holder is raised to release the tool by a lock spring, on the release of a catch which is returned by a spring.

Abstract: 1533686 Chemically strengthening glass containers YAMAMURA GLASS KK 18 April 1977 [4 June 1976] 16006/77 Heading C1M A method of chemically strengthening a glass container comprises applying to the outer surface and inner surface of the glass container an aqueous solution of mixed potassium salts consisting of potassium nitrate and at least one potassium salt selected from potassium chloride and potassium sulphate, the temperature of the glass being lower than that of the aqueous solution thereby depositing out the potassium salts on the outer surface and inner surface of the glass container by virtue of the temperature difference to form a potassium salt adhered layer, then drying the container, holding the glass container at an elevated temperature below the strain point of the glass but as near the strain point as possible for a period of time sufficient to cause replacement by ion exchange of cations in the glass container by potassium ions so that a compressive stress layer is formed on the outer surface and inner surface of the glass container, the proportion of potassium nitrate to at least one potassium salt selected from potassium chloride and potassium sulphate used to form the potassium salt adhered layer being such that when the layer is heated at the aforementioned elevated temperature 10-80% by weight of the potassium salts are present in the solid phase, thereby preventing the fused potassium salts from flowing from the surfaces of the glass container, cooling the glass container to room temperature and removing the residual potassium salts. The glass container may previously have been subjected to a coating of a metal oxide having a high abrasion resistance, e.g. tin oxide and titanium oxide.

L., 98, Park Road, and FARRINGTON, F., 57, Higher Swan Lane, all in Bolton. June 4, 1935, No. 16034. [Class 100 (ii)] Stencils, particularly for use with highlycorrosive print colours, are prepared by spraying on to selected areas of a gauze formed of corrosion-resistant material, a molten corrosionresistant metal of high melting-point so that such metal fills up and hardens in the interstices of the areas to which it is applied. The gauze may be made of stainless steel, phosphor bronze, or nickel and the sprayed metal is preferably of the same composition as the gauze to which it is applied. Paper, wax, chrome-gelatine or other suitable material, or an auxiliary stencil may be employed during the spraying operation to protect the parts of the gauze which are to remain permeable. The metal deposit is subsequently calendered and polished. According to the Provisional Specification, a readily-fusible metal such as tin or a tin alloy may be employed in spraying the gauze, in which case the deposit can be removed easily and the gauze made available for further use.

A contact printing apparatus has a light stop 18 between the light source 17 and the transparent sheet-supporting surface 11. The elongated light source is disposed symmetrically above surface 11, and the central part of the surface would thus receive more intense illumination than the outer parts. By providing the stop 18, which intercepts light falling directly on the central part, a more uniform illumination is achieved. A further improvement is provided in that the housing has sloping side walls 12, 52, which diverge from the lamp 17 to the edges of surface 11, and which act as reflectors. An additional housing part formed by walls 13, 32 encloses a developing section 27. In the form shown, the apparatus is set up for copying a page of a book 26, which is pressed against the under side of surface 11 by a pressure plate 20 under the action of a lever 21, 22. In a different arrangement, Figs. 4 and 5 (not shown), the book (44) rests against the top and side of the apparatus. A pressure flap (46) may be hinged at (45) to an adjustable slide (48), and held against the book by a spring (49).
