Abstract: 483,733. Treatment of seeds and growing plants; germinating - appliances. TEES SIDE BRIDGE & ENGINEERING WORKS, Ltd., INTENSIVE CULTIVATIONS, Ltd., and LEWIS, W. A. Sept. 21, 1936, No. 25638. [Classes 6 (ii) and 58] A liquid retaining and distributing tray for soil-less seed-germination cabinets is provided with overflow orifices disposed at a predetermined height above, and distributed over, the base of the tray, and with spaced intercommunicating concavities disposed around the orifices. The tray 10 may have a rim 11 provided with flanges 12 to rest upon a support. The base 13 is shown corrugated in two directions at right-angles to one another. At parts 35 intermediate between the points of intersection of the two series of corrugations the upper parts of the corrugations are depressed, so that a series of spaced humps or projections 16 is provided, each projection being surrounded by troughs or concavities 17 which communicate with adjacent concavities, over the parts 35, to form a series of interconnected concavities. Orifices 18 are formed at the top of some or all of the humps 16. They may have serrated orifices and may be evenly or unevenly distributed. The trays are superposed in the cabinet and water or nutrient liquid supplied to the uppermost, the surplus passing through the orifices 18 to the next tray below and the surplus from that tray to the next, and so on, the liquid remaining in each tray being determined by the height of the orifices and being retained in a series of interconnected pools. The top tray may have perforations in the bases of the humps or in the intercommunicating cavities instead of at the top of the bumps, so as to act only as a liquid distributing tray. The orifices may be more numerous adjacent the outer edges of the tray. The corrugations may extend in any direction and at any angle to one another.

Title: Improvements in or relating to a method for synthetically making diamond
IPC: B01J3/06
Filed: 1963-06-27
Abstract: Diamond is made synthetically by subjecting a mixture of graphite, particles of a metal selected from iron, nickel and cobalt or of an alloy of iron, nickel or cobalt with carbon, silicon or phosphorus of a grain size larger than 80 mesh/inch, and a fine powder of a carbide or carbides of a metal or metals selected from titanium, vanadium, molybdenum, tantalum, niobium, tungsten, chromium and manganese of a grain size of smaller than 100 mesh/inch, to a pressure of from 57,500 to 75,000 atmospheres at a temperature of from 1200 DEG  to 1600 DEG  C.  The grain size of the graphite particles may be from the grain size of the metal particles to the grain size of the carbide powder, and is preferably from 40 to 100 mesh/inch.  The conversion is first effected in the central portion of the reaction mixture, then the reaction mixture is heated until the temperature of the central portion of the reaction mixture increases by from 300 DEG to 500 DEG  C., when the outer portion of the reaction mixture will have reached a temperature at which conversion to diamond can occur.

Title: Method of and apparatus for lifting upper and lower box moulds off a pattern plate, and conveying away the finished box, in turntable foundry moulding machines
IPC: B22C7/04
Filed: 1956-08-23
Abstract: 841,143. Moulding-machines. BADISCHE MASCHINENFABRIK AKTIENGESELLSCHAFT SEBOLDWERK. Aug. 23, 1956 [Aug. 24, 1955], No. 25837/56. Class 83 (1). A method, in turntable moulding- machines, of lifting upper and lower boxes of a moulding-box from a pattern-plate, and subsequently conveying away the finished half-mould, comprises lifting the pattern-plate and box rapidly relatively to the turntable, and thereafter first separating the box slowly from the pattern-plate and then moving it rapidly upwardly for lowering on to a short roller-conveyer for removal, after which the pattern-plate is again lowered on to the turntable, all the operations taking place one after the other and automatically. The machine comprises a turntable 10 and a lifting-off-station IV. The stripping-device at station IV comprises an outer cylinder 18 containing a piston 21 supporting a table 15 carrying lifting-pins 22, and an inner piston 19 carrying a table 16 on which the pattern-plate 1 and mould-box O are supported. Guide-rods 66 attached to the table 16 pass through stops 20, and incorporate dashpot devices 67. The piston 19 is normally held at the top of its stroke in the chamber 64 by pressure-air from the line 28. In operation, pressure-air is fed beneath the piston 21 so that the tables 15, 16, with the pattern and box thereon, rise from the turntable 10 at the speed of movement of the piston 21. When the dashpot devices 67 engage the stops 20, the table 16 is slowly brought to a standstill, relative movement of the tables causing the pins 22 to slowly lift the box from the pattern. After movement of the table 16 has stopped, the box moves from the pattern at the speed of movement of the piston 21. Towards the end of the upward movement of the box, rails 70, Fig. 3, upon which the stripping-pins 22 are supported, are moved by engagement of a cam-follower 38 in a cam groove 40,. allowing the pins 22 to descend from ramps 69 on the rails and thereby deposit the box on to a roller-conveyer 68 carried by the table 15. Operation of a limitswitch 41 in the top position causes removal of the flask from the conveyer 68 to an adjoining conveyer, by actuating a pusher. When the box has left the conveyer 68, actuation of a limit-switch 43 causes the piston and pattern to be restored to their initial positions for commencement of another cycle.

Abstract: 1,074,833. Travelling wave tubes. VARIAN ASSOCIATES. June 24, 1964 [July 12, 1963], No. 26191/64. Heading H1D. A travelling wave tube has a slow wave structure which comprises at least two distinct sections 15, 17, each of which are designed to be in interaction relationship with the electron beam travelling between a gun 12 and collector 13, each section having distinct and uniformly recurrent slow wave sections which cause the sections to have unlike synchronous voltages. The algebraic sum of the gain versus beam voltage characteristic for each section is arranged such that the composite characteristic is substantially flat at the maximum power output operating conditions, the operating beam voltage being chosen at the flat portion of the characteristic, thus increasing the efficiency of the tube. As shown, the delay line may be helical with two sections of equal axial extent. Alternatively three sections may be used, or a loaded filter type slow wave structure used.

Title: Improvements in or relating to treatment of fuel gases
IPC: C10K1/18
Filed: 1931-09-19
Abstract: 394,310. Gas-purifying materials. KOPPERS CO. OF DELAWARE, Koppers Building, Pittsburg, U.S.A.-(Assignees of Jacobson, D. L. and Shively, W. L.; Koppers Building, Pittsburg, U.S.A.) Sept. 19, 1931, No. 26294. Convention date. Sept. 19, 1930. Void [Published under Sect. 91 of the Acts]. [Class 55 (ii).] Gum-forming constituents such as indene, styrene, or coumarone, are removed from fuel gases by treating them with solvents such as heavy oils to absorb these substances, which are polymerized, and may be removed from the solvents, which may be used again for treating under gas. The solvent is treated with a polymerizing agent such as sulphuric acid, or sulphur chloride, or with oxygen, or hydrogen under pressure, and the polymerized impurities are precipitated, and may be removed from the washing oil. The fuel gas enters a scrubber 3 by a pipe 2, and is sprayed with a heavy oil through nozzles 27, and may then pass through a superposed scrubber 4 in which it meets with fresh oil from nozzles 22 to remove any remaining impurities, the purified gas escaping through outlet 13. Impure oil from the sump 29 is forced by a pump 23 through pipe 34 and nozzles 35 into a chamber 36 in which it is treated with sulphuric acid from pipe 38, the liquid being agitated by stirrers 41. Acid and polymerized gums are withdrawn through pipe 43. The oil is then treated in a neutralizing vessel 50 with caustic soda from a pipe 54, and sludge and salts are drawn off through an inlet 56, the purified oil being recirculated by a pump 25 through pipe 59 and 26 leading to the scrubber. If a solid polymerizing agent such as aluminium chloride is used, the oil from the scrubbers is delivered by a pipe 61, Fig. 2, to a vessel 64 in which it is treated with the solid introduced from a hopper 67. The oil mixture is passed to a pressure vessel 71 heated by a coiled pipe 73, and is then discharged into a tank 81, and fed to a filter press 86 from which the pure oil is led off through a pipe 87 and returned to the scrubber. The contaminated oil may be hydrogenated by introducing a catalyst through the hopper 67, and hydrogen through inlets 90, excess hydrogen escaping through pipe 92. The resin-forming constituents may instead be oxidized by supplying oxygen through pipes 90. In a modification, the gum-forming compounds may be removed from the oil by treatment with gas which is re-circulated through an acid bath, or a heater and chamber containing a catalyst.

Abstract: 452,616. Flushing-valves. LEWIS, T., 60, Leeson Road, Bournemouth. Sept. 24, 1935, No. 26484. Convention date, Aug. 5. [Class 135] Flushing-devices of the kind in which a main valve 12 is operated by a piston 16 sliding in a cylinder 7 having a port 22 connected to the inlet, the piston being operated by liquid pressure controlled by a relief valve, and in which the piston is made hollow and exposed below to liquid pressure from the inlet, holes 17 for the entry of liquid into the piston and a manually operated valve 14 for escape of liquid from the piston being provided, are characterized by the fact that the total aperture of the holes 17 is less than that of the valve 14 in order to retard upward movement of the piston. The cylinder 7 rests on a shelf 9 and is spaced at 8 from the casing. Liquid has access to the inside of the piston from the inlet 3, Fig. 4, by way of the space 8, port 22, and the holes 17 in the top of the piston. When the valve 14 is displaced by means of a handle 32 and plunger 26, the pressure is diminished above the piston which thereupon rises carrying with it the main valve 12. The relation between the holes 17 and the valve 14 ensures that the valve 12 will open slowly. A sleeve 19 is also raised by the piston and eventually the inlet 3 is connected with the outlet 4 by slots 20, 21 in the sleeve. When the handle 32 is released a spring 18 closes the valve 14 and the piston sinks as water from the hole 22 accumulates in the cylinder 7 and piston 16.
