IPC: G21B1/00
Filed: 1957-01-18
Abstract: 830,255. Nuclear fusion reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 15, 1958 [Jan. 18, 1957], No. 1920/57. Drawings to Specification. Class 39(4). In a thermonuclear reactor comprising a vessel for containing a gas within which thermonuclear reactions are produced, the vessel is enveloped, at least in part, by a first blanket containing material fissile by fast neutrons, e.g. uranium 238, and by a second blanket containing lithium 6 which absorbs neutrons produced in the first blanket and produces tritium. The heat produced in the blankets may be extracted by conventional means and used to generate electricity. The effect of adding the uranium blanket is to multiply the power produced by the reactor and to make possible a net gain of power from a reactor which of itself does not produce a set gain. Specification 830,252 is referred to.

Abstract: 879,655. Extracting sugar &c. RAFFINERIE TIRLEMONTOISE. Jan. 20, 1958 [Jan. 29, 1957], No. 1929/58. Classes 81 (1) and 127. [Also in Group XIII] An apparatus for contacting solids and liquids, particularly for extracting sugar &c. by diffusion with water and extracting products adhering to solid materials, includes a drum with a horizontal axle shaft 7, Fig. 19, a screw (or helicoid) conveyer 2 arranged in and rotatable with the drum, a liquid supply at the liquid inlet end and a solid supply at the liquid outlet end, a plurality of screens 6 extending between the turns of the screw conveyer and defining cells 8 extending between two successive screens, the angular spacing between two successive screens being equal to where n is the number of screens per screw pitch, and each screen has a relatively fixed part 9 adjacent the drum shell and a part 10 adjacent the shaft movable by control means with respect to the fixed part during that portion of the rotation of the screw conveyer which corresponds to the ascent and descent of the screen to and from the upright position; the principle of operation is illustrated by Figs. 2 to 7 in respect of the segment ab of material. The screens 10 are moved to a retracted position behind the screens 9 by hydraulic jacks 35, Fig. 22, operating by oil pressure through a lever system 26, 24; proper locating of the screens 10 is ensured by movement of a slider 37 in guides 38. At. the end of the conveyer from which solid material is discharged, the screen parts are replaced by a solid wall having a fixed part 68, Fig. 19, and a movable part 69. Liquid is supplied to the cell provided between the solid.wall and the screen immediately following, but only from about the time the movable part of that screen is moved with respect to the fixed part to about the time when the screen begins the ascent from the bottom position during the rotation of the conveyer, to prevent  mixing of the liquid with the solid material being discharged. The feeding of solid material to the cells 8 and the removal by overflow of liquid is described with reference to Figs. 16 and 20 (not shown). The drum may be supported on rollers. In alternative embodiments, the angular spacing of the screens may be where N is the total number of cells and the moving parts 10 of some of the screens may be omitted when the batches of solid material employed sufficiently fill the cells 8; the hydraulic jacks may be replaced by mechanical means.

Title: A method for the extraction of solid matters from liquids obtained in pressing animal products
IPC: B04B1/12
Filed: 1938-01-21
Abstract: 492,582. Separating liquids and solids. AKTIEBOLAGET SEPARATOR. Jan. 21, 1938, Nos. 2045, 2046, and 2047. Convention dates, Jan. 21, 1937, Sept. 8, 1937, and Oct. 6, 1937. [Class 23] Solids and liquids obtained by pressing animal products are separated by means of centrifuges with peripheral outlets for continuous or intermittent discharge of solids, and an outlet for a liquid, preferably glue water, close to the axis ; the separator bowl is of such construction and capacity that the extraction of solids can be wholly effected by treatment of the material discharged through the peripheral outlets. The process is specially applicable in the production of fish flour and fish oil. The fish is heated by steam and conducted to screw presses ; the cake from the presses is dried, ground and sifted to flour. The liquid from the presses contains oil and water with suspended and dissolved fish particles; it is passed through strainers to the separators. Where it is desired to use one machine to separate sludge and oil from another liquid, the type used is that shown in Fig. 1 ; it has a central inlet 1, a perforated disc pack 3, an outlet 4 for oil, nozzle outlets 5 for the sludge and an outlet 6 for the other liquid. Part of the discharged sludge concentrate may be conducted back to the bowl to obtain continuous operation and the remainder is passed to decantation tanks or flotation channels from which the sludge is taken to a dryer. Where large quantities are dealt with, the oil is first separated by centrifuging and the remainder is fed to nozzle separators of the clarifier type with non-perforated discs and only one liquid discharge outlet. In a modification the separator has two stages in order to ensure that the heavier liquid is free from solids. The material from the inlet 1 passes through the perforated disc pack 2, Fig. 3, in the lower part of the bowl and the oil is discharged from the outlet 3 ; the remainder of the material passes to the discs 5 in the upper part of the bowl, and the separated liquid passes to its outlet, while the sludge passes to the discharge nozzles 6. The discharge of sludge can be assisted by introducing, through the tube 8 and channels 7, a liquid containing solids already separated.

Abstract: 1,170,681. Controlling change-speed gears. ROBERT BOSCH G.m.b.H. 16 Jan., 1967 [21 Jan., 1966], No. 2152/67. Heading F2D. Ratio shifts of a change-speed gear are effected by a cam 53 formed on a cam-shaft 50 having a screw-threaded portion 55 engaging a fixed nut 56 so that the shaft moves axially as it is rotated, at least two levers 43 connected to ratio shift elements of the gear being selectively engageable by the cam 53. Gearing.-A four-speed and reverse gear B comprises coaxial input and output shafts 11, 13 and a layshaft 12 driven from the shaft 11 by pinions 21, 20. Gear-wheels 15, 17, 19, constantly meshing layshaft pinions 14, 16, 18, are freely rotatable on the output shaft 13 and are clutchable thereto by positive clutches 33, 32 for establishment of first, second and third ratios, while clutch 32 engages the input pinion 21 for direct drive fourth. A reverse idler 23 is movable axially by shift fork 31 to mesh a pinion 22 and a gear-wheel 24 for reverse. Gear 24 moves axially with the clutch 33. Control.-The cam-shaft 50, driven via reduction gearing (63) from a reversible electric motor (64), (Fig. 1, not shown), extends through apertures in three side-by-side levers 41-43 pivoted on a common shaft 44 and engaging respective parallel shift rods 25, (26, 27) to which are secured shift forks 30, 29, 31. In each lever, staggered sections 51, 52, each half the width of the lever, define the aperture sides, projections 59 thereon engaging opposite sides of the cam-shaft or cam. The width of cam 53 is 75% of the width of a lever, and a recess 54 in the cam-shaft diametrically opposite the cam 53 is slightly wider than two levers. The pitch of thread 55 equals one lever width. Starting from any gear-engaged position, a 90 degree rotation of the cam-shaft disengages the existing ratio to give a neutral setting, and a further 90 degrees rotation establishes a new ratio. The two levers not required for establishment of a particular ratio are locked in their central, neutral positions by the cam shaft. Contacts (60), (Fig. 1, not shown) on the cam-shaft engage fixed contacts (61) to provide signals representing the cam-shaft position to a control device for the motor (64).
