Title: Improvements in or relating to synchronizing apparatus for maintaining two engines or other machines at equal speeds and at a predetermined or adjustable phase angle relationship
IPC: G05D13/00
Filed: 1950-03-25
Abstract: 675,406. Speed governors. PARKER, R. D., POUNDER, C. C. and REBBECK, Sir F. E. March 25, 1950, No. 7538/50. Class 57 In or for machinery having two reciprocatory or rotary engines maintained at substantially equal speeds and at a predetermined phase angle relationship by synchronizing apparatus driven from the planetary gearing 1 of a differential gear interposed between the two machines, the synchronizing apparatus comprises a pawl carrier 5 having a pair of pawls 4 pivoted thereon and adapted to engage between them a crank pin 3 driven from the planetary gearing, the pawl carrier being pivoted on an axis 6 spaced from the pivotal axes of the pawls and being adapted to control the speed regulating mechanism of at least one of the machines. The synchronizing apparatus is operated by a differential gear comprising sun gears c, d, on shafts a, b driven in opposite directions by the respective machines. The planet carrier 1 is connected to an indicator 31 through bevel gearing and an adjustable coupling comprising a worm wheel 26 on a shaft 25 in mesh with a worm 27 carried by a bracket 28 on a shaft 29. Upon adjusting the worm by a handle 30 the angular relationship of the indicator 31, and the planet carrier, which may also carry a pointer, may be varied thus changing the phase relationship of the machines. In addition or alternative to the adjustable coupling a friction clutch may be used. The indicator shaft carries a crank 2 having its crank pin 3 engaging between the pawls 4 which are biassed by a spring 15. Movement of the crank pin thus causes a pivotal movement of the pawl carrier 5 and this movement is transmitted through a slide block 22, engaging in an arcuate guide 7, and link 21, bell crank 33, and links 8 to the speed regulating levers 9, 10 of the respective machines. The movement of the link 21 may be varied or the synchronizing apparatus may be rendered inoperative during manual speed adjustment by a hand lever 23. The pawls 4 are tripped during excessive movement of the crank pin when further movement of the pawl carrier has been limited by stops 18.

Title: Improvements in and relating to the condensation of zinc from its vapour in gaseous mixtures
Inventor: ROBSON STANLEY
IPC: C22B19/18
Filed: 1946-03-12
Abstract: 611,929. Distilling zinc. NATIONAL SMELTING CO.. Ltd., and ROBSON. S. March 12, 1946, No. 7620. [Class 82(i)] In a method of condensing zinc from gases containing zinc vapour in two stages, the vapour is brought directly from the producing unit into intimate contact with a shower of molten zinc in a first stage and thence to a second stage wherein the shower of molten metal is at a temperature below the minimum practicable for tapping zinc. As shown, the vapour from a zinc blast furnace enters a first chamber 2 where a shower of molten zinc at 500-550C. is produced by a rotary device 4, the residual vapour passing into a second chamber 3 where a shower of molten metal, e.g., lead, is produced by a rotary device 6 the temperature at this stage being maintained below that at which zinc may be tapped. The metal in chamber 3 may be circulated through pipes 19 and 20, the zinc being extracted at some point outside the chamber. The metal in the second stage may be zinc, Fig. 2 (not shown) which overflows into the first chamber. The zinc vapour which remains in the final gases may be condensed in a stack as blue powder and fall into the final chamber as described in Specification 611,930. In a modification, Fig. 3 (not shown), the second stage may be subdivided into two and the metal and gas may flow in counter current. Details of shower producing devices, horizontal and vertical, are illustrated in Figs. 4 to 10 (not shown). Specifications 572,960 and 572,961 also are referred to.

Abstract: 790,531. Differential pressure gauges. REESE, W. M. March 12, 1956, No. 7621/56. Class 106 (2). A differential pressure gauge comprises a housing 5 divided into two chambers 8, 9 by a centre plate 10 which encloses another chamber 24 with a passage 28 opening directly into a bellows 21 whose outer end 21<SP>1</SP> moves in the chamber 9 and is connected to valves 31, 32 controlling the passage 28, while the chamber 24 is closed out of direct communication with a bellows 18, with outer end 18<SP>1</SP> movable in the chamber 8, but communicates therewith through a single indirect passage 45, 46. The gauge may be used for measuring the drop of pressure through an orifice plate in a gas or liquid flow line, the high and low pressure sides thereof communicating through pipes 3, 4 with the chambers 8, 9. The bellows are filled with a suitable liquid adapted to flow back and forth in response to variations in pressure in the chambers 8, 9 acting against adjustable calibration springs 41. Normal flow is controlled by the valves 31, 32 so that the displacement of the valve shaft 34 gives a measure of the pressure difference. Movement is transmitted from the shaft 34 to indicating or recording apparatus by a disc 53 on the shaft 34 acting on a roller 54 carried by an arm 55 mounted on a pivoted shaft 59. Compensation for variations in the volume of liquid in the bellows 18, 21 due to temperature variation may be provided by linking the shaft 34 to the free end of the arm 55 by a bimetallic strip either straight, U-shaped or multi-looped. A pulsation dampener restriction valve 47, of needle type and manually adjustable, provided in the passage 45, 46 permits normal flow between the bellows, but restricts excessive flow due to sudden surges.

Abstract: 492,274. Vehicle bodies; window frames. ASHDOWN (BIRMINGHAM), Ltd., H. E., and SNELL, A. G. March 16, 1937, No. 7665. [Class 108 (i)] [Also in Group X] In order to conceal the edges of an opening 1, such as a window-opening, in a vehicle body, which opening may be formed slightly greater or less than the correct size, a frame 2 formed of a single plastic moulding, e.g. of the material known under the Registered Trade Mark " Bakelite," of thin curved section is adapted to be secured in the opening, the frame having at intervals on its outer surface projections 5 the outer extremities of which are adapted to fit approximately an opening of maximum size, the projections being of small cross-sectional area in the plane of the frame at their outer ends so that they can be easily reduced in length by a rasp &e. to an extent necessary to fit the frame in an opening of less than maximum size or be sheared off by pressing the frame into the opening. As shown, V-shaped projections 5 are formed on bases 3 moulded to the frame, the surfaces 4 of the bases being able to enter an opening 6, Fig. 5, of minimum size while the outer ends of the projections co-operate with or lie just outside the edges 7 of an opening of maximum size. The frame is fixed in the opening by screws passing through holes 8, Fig. 3, preferably between each pair of projections, in the bases 3. To facilitate entry of the frame into an opening, the projections may increase in length from the side of entry of the frame.

Title: Americium-curium separation
IPC: C22B60/02
Filed: 1964-02-24
Abstract: 991, 099. Separation of curium and americium. UNITED STATES ATOMIC ENERGY COMMISSION. Feb. 24,1964 [May 3, 1963], No. 7678/64. Heading G6R. Curium is separated from americium by introducing a mixture containing these elements into a molten magnesium halide-containing flux, adding a magnesium-zinc alloy, and separating a metal phase containing curium from a flux phase containing americium halide; alternatively the mixture may be introduced into the alloy and then the flux added. The elements may be present in the original mixture as metals, oxides, or halides, curium being reduced to metal in all cases. Preferably the Mg-Zn alloy contains 25-95% by weight of Mg and the process is carried out at 600‹-900‹C. The magnesium halide flux may also contain alkali metal or alkaline earth metal halides; examples are a mixture of MgCl 2  and LiCl and a mixture of NaCl, KCl, and MgCl 2 . After separating the layers by decantation or by cooling and mechanical means, Mg and Zn may be removed from the metal phase by volatilization in a vacuum or an inert atmosphere, leaving a residue of curium. The original curium-americium mixture may be obtained by neutron bombardment of americium 241 which has been separated from neutron-bombarded plutonium 240 by the process of Specification 991,100.

Title: Process for the manufacture of esters of polycyclic alcohols
IPC: C07J1/00
Filed: 1935-04-08
Abstract: The process described in the parent Specification which comprises the manufacture of esters of polycyclic alcohols by subjecting esters of the male sex hormone and rosterone C19H30O0 to the action of reducing agents to convert the keto group at position 17 into a secondary alcohol group, is applied to esters of saturated or unsaturated polycyclic alcohols similarly constituted to the male sex hormone. In the case of unsaturated compounds such as dehydroandrosterone, the double bond in the nucleus becomes saturated.  In examples: (1) Dehydroandrosterone monopropionate is hydrogenated in the presence of a platinum oxide catalyst using anhydrous propionic acid as the solvent to yield a mixture of isomeric monopropionates of androstandiol; (2) Dehydroandrosterone benzoate is hydrogenated in the presence of a nickel catalyst obtained by the method of Raney, the solvent being methyl cyclohexane, and the product being androstandiol; (3) The acetate of hydroxyetio-allo-cholanone-(17) is hydrogenated by being dissolved in alcohol and treated with sodium amalgam, the solution being kept just acid by the gradual addition of acetic acid.  The product consists of a monoacetate of 3:17-dihydroxy-etio-allo-cholanone.  Specification 443,463 is referred to.
