Abstract: 621,878. Hydraulic machines ; manuallyactuated valves. NUFFIELD MECHANIZATIONS, Ltd., and MERRITT, H. E. Aug. 21, 1946, No. 24870. [Classes 69 (ii) and 135] The supply of pressure liquid to the power cylinders 15, 16 of the forward and rear implements respectively of an agricultural tractor is controlled by piston valves F, R, slidable in bores in a block 4 having inlet and exhaust ports 24, and 5, 6, 27 respectively, and ports 22, 23 connected to the cylinders, and operable through links 9, 10 by a hand-lever 12, the link 9 having ball ends engaging the heads of the valves. The valve R is releasably held in either of its end positions by a spring-loaded ball engaging either of the grooves 17, 18 in the valve. As shown, the pump 1 discharges straight through the valve block from the port 24 to the port 27. In operation, movement of the lever 12 from the position shown to the vertical one, moves the valve F upwards to open the cylinder 15 to the pressure liquid and raise the forward implement. Further movement of the lever towards the right results in the cylinder 16 also being opened to pressure liquid and raising of the rear implement. Return movement of the lever towards the vertical opens the cylinder 15 to exhaust past the chamfered upper end 21 of the valve F and the port 5, while further movement of the lever to the first position also opens the cylinder 16 to exhaust through the port 6, thus lowering the implements in turn. In a modification, the spring-loaded ball is replaced by a spring- loaded block which bears against a flat on the valve R.

Title: Improvements in radioactive material
IPC: G21G4/04
Filed: 1927-09-21
Abstract: 278,347. Fischer, A. Sept. 29, 1926, [Convention date]. Radiations, treating diseases with. - Radioactive material is prepared from radium and mesothorium or their salts by incorporating these with metals or alloys by causing intimate contact with the metal or alloy and subjecting the product to mechanical treatment, such as hammering, rolling or wire drawing accompanied by heat treatment if desired, the temperature being raised in some cases to the melting point. Alternatively, the radio-active materials may be deposited on the metal or alloy by electrolysis and, prior to the incorporation treatment, may have electrically or otherwise deposited thereon a covering layer of metal. The metals employed are those which are not readily oxidized such as platinum or gold. In an example, the metal or alloy is first hammered or drawn into thin sheets or wires and coated with the radio-active substance, with or without binding-material. The coated sheets &c. are now hammered, rolled, &c. until the added material is thoroughly incorporated. For dental purposes, e.g. insertion into the cavities of decayed teeth, the finished product is drawn into very fine wires. In a second example, the metal or alloy is heated to a high temperature, 1000‹ C. or more, and the radioactive substances are added thereto together with organic bodies, such as glycerine, sugar, citric acid &c., to act as reducing agents when radioactive salts are employed. The alloys so formed can be treated as in the previous example. In a third example, the radio-active substances are mixed with the constituents of an enamel with which the previously-prepared foil, wires, &c. arecoated and then fixed. Reference is made in the Specification to the use for medical purposes of radio-active bodies enclosed in small soldered metal tubes or in sealed glass tubes contained in a protective metal casing, and also to radio-active preparations secured to thin metal sheets or to a fabric base by means of varnish.

A liquid mixture is partially vaporized by atomizing it through distributer 3 by means of steam supplied through line 5. The turbulent mixture of liquid, vapour and steam issuing from the distributer 3 rapidly passes down the column 4 to the separator 7. Any liquid that separates out on the walls of column 4 is redistributed in the turbulent mixture passing down the column by annular.distributers 6. In separator 7, the droplets of the liquid residue are separated from the mixture of vapour and steam, and the liquid residue is removed continuously via line 8. The mixture of vapour and steam passes via line 9 into the condenser 10. The condensate formed in condenser 10 passes via line 11 into a gravity separator 12 wherein the distillate is separated from the condensed steam. In an example, methyl methacrylate is separated from a reaction mixture, produced by treating acetone cyanhydrin with methanol and sulphuric acid, by atomizing the mixture with steam at 83 ‹C. The turbulent mixture thus produced is at 68 ‹C. and passes from the distributer 3 into the column in which a vacuum of about 200 mm. Hg. is maintained. The residence time in the column is less than 1 second.
