Title: A method of and apparatus for separating liquid phases
Inventor: ELTENTON GEORGE CHARLES
IPC: B04B1/00
Filed: 1962-05-30
Abstract: 1,006,694. Separating liquds. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. May 30, 1962, No. 20840/62. Heading B1D. In a process for the separation of a non- Newtonian liquid from a liquid or liquids of other than non-Newtonian type, a mixture of said liquids is delivered through a pipe 3 to the upper end of an inclined perforated cylinder 1 made of e.g. wire gauze, which is lodged within a rotatable imperforate cylinder 2, cylinder 1 being wetted by the non- Newtonian liquid less than by the other liquid or liquids when the cylinders are rotated about an axis A-A by a belt 12 engaging with a pulley 9, whereby the non-Newtonian liquid is rolled into a substantially cylindrical form or "sausage" which flows from cylinder 1 through a tapered end 4 whereas the other liquid or liquids flow through the perforations of cylinder 1 into an annular space defined by the two cylinders and thence through the lower end 11 of cylinder 2. Cylinder 1 is attached to cylinder 2 by lugs 5, cylinder 2 being supported by rollers 7. To prevent the non- Newtonian liquid rising out of the lower half of cylinder 1 the speed of cylinder 2 is restricted to e.g. 10-30 r.p.m. Axis A-A is inclined at an angle of not more than 60 degrees, and preferably not less than 5 degrees, relative to the horizontal. The interstices of the gauze, or perforations, of cylinder 1 are each 0À0001- 0À0025 inch<SP>2</SP> in area over an area of at least 30% of the internal surface of the cylinder, the number of interstices or perforations being 100-1500 per inch<SP>2</SP>. The wire gauze may be of B.S. mesh size 10-50 and may be masked by an imperforate screen (not shown) over an area of 30-40% of the length of cylinder 1 from its upper end, the screen being situated internally of the cylinder. The volume of mixture passed through the cylinders may be from one to four times the volume of cylinder 1 per hour, an example of such a mixture being a gel containing 60-65% sodium (C 8 -C 13 ) alkyl benzene sulphonate in an aqueous liquid.

Title: Improvements in or relating to propellers
IPC: B64C11/30
Filed: 1960-06-14
Abstract: 991,744. Axial-flow compressors and fans. H. T. GRUT. June 9, 1961 [June 14, 1960], No. 20868/60. Heading F1C. [Also in Division B7] In a compressor or ducted fan incorporating an impeller within a duct 11 of the compressor or fan the impeller has means for applying a torque to both ends of each of the blades 10, said means including elements (element 13 rotating with the impeller and lugs 14 on the blades projecting into slots 12 in the element) situated within the wall of the duct for applying the torque at the outer tip of each blade so that the blades may be subjected to variable amounts of elastic deformation whereby the pitch and twist thereof are varied in dependence upon the relative rate of advance of the impeller through the surrounding medium. Thus if the blade root is rotated about its longitudinal axis by a pitch-varying means, the blade tip will move from the mid position shown in Fig. 2, thus varying the pitch of the blade, until the lugs 14 contact a face of the slots whereafter continued rotation of the blade root results in the application of a torque or twist producing an elastic deformation which varies the twist and pitch of the blade. Specification 880,590 is referred to.

Heading C2C. 4-Nitroimidazole derivatives of the formula wherein Hal is a chlorine, bromine or iodine atom, R is a hydrogen atom or an alkyl or aryl radical and A is a bivalent aliphatic hydrocarbon radical, are prepared by ether cleavage of the corresponding nitroimidazoles substituted at the 1-position by a radical of the formula -A-O-B-X where B is an aliphatic hydrocarbon radical and X is a hydrogen or halogen atom or a nitro, sulphuric acid, sulphonic acid or hydroxy group. The compounds have chemotherapeutic properties. Asymmetric dihaloalkanes may be obtained as by products of the above process.

Abstract: 936,457. Endless conveyers. SPOONER DRYER & ENGINEERING CO. Ltd. June 9, 1960 [June 19, 1959 ; Feb. 6, 1960], Nos. 21043/59 and 4276/60. Class 78 (1). In a conveying system for conveying rodlike articles, such as welding rods, through a heat treatment chamber 10, the articles are fed down a shoot 22 to a feeding conveyer 28 having compartments 30 and means for ejecting the excess articles if there are more than one article in any compartment, as disclosed in Specification 825,962. The articles are delivered from the conveyer 28, one at a time, into slots 46 in racks 12 which are suspended from supports 44 on endless chains 18 driven in synchronism with the conveyer 28 and which engage a ramp 48 at the loading station 16 to incline the racks. The racks are transferred from the chains 18 to endless chains 14, passing through the chamber 10 and driven at a slower speed than the chains 18, at a transfer wheel 20 and, having passed through the chamber, the racks are transferred to chains 62 travelling at substantially the same speed as the chains 18. As the racks are lowered on the chains 62, projections 74 on the racks engage a guide 72 which causes the rack to tip to discharge the articles, whereafter the racks are transferred to the chains 18. In a modification, Fig. 3 (not shown), the articles are transferred from the feeding conveyer to an inclined guide down which they slide on to the chamber conveyer by rotating arms. In a further modification, Figs. 1, 2 (not shown), of the second Provisional Specification, the articles are fed to the feeding conveyer by an endless belt conveyer and the feeding conveyer comprises a conveyer for separating the articles and a pair of endless chains for feeding the articles to the racks.

Abstract: 712,022. Centrifugal governors. GENERAL MOTORS CORPORATION. Aug. 28, 1952 [Sept. 11, 1951], No.'21601/52. Class 57 [Also in Group XXIX] A speed-responsive apparatus comprises a driven shaft, a flexure ring, surrounding the shaft, means drivingly connecting the ring with the shaft and supporting the ring for flexure about one of its outer peripheral edges, weights connected to the ring to cause flexure thereof due to centrifugal force and mechanism for transmitting movement of the weights to a movable member to be positioned in accordance with the speed of the shaft. Weights 55 are secured by pins 54 to a flexible disc 53 engaged at its inner periphery by hooks 56 provided on the weights and having its outer periphery resiliently urged by a U-sectioned ring 60 Fig. 15, into contact with a rotary housing 50 wherein it is located by pins 52. The housing 50 is splined to a shaft 36 supported in bearings 37. 39 and splinedly connected by a quill shaft 40 to engine driven shaft 31. Rotation of the housing 50 and weights 55 causes the latter to move outwardly and to the right and flex the disc 53 about its outer periphery. Axial movement of the weights is transmitted by arms 65 provided on three of the weights to a sleeve 67. the arms engaging a recess in the sleeve 67 which slides on the shaft 36 and has a further recess 67a engaged by rollers on the arms of a yoke 70 pivoted on a tube 71 carried by a block 72 threaded to receive the screw portion 73 of a rod 74 having a further portion 76 screwed into a part 35 of the governor casing, the screws 73 and 76 being of slightly different pitch to permit micrometer adjustment of the block 72. Movement of the end of the yoke 70 remote from the sleeve 67 is transmitted through a hydraulic servomotor (see Group XXIX) and a cam plate to a rod which may. for example, control the flow of fuel to the combustion chambers of a gas turbine engine.

Title: Uranium separation process
IPC: C01G56/00
Filed: 1961-06-15
Abstract: Uranium oxides are separated from the oxides of other actinide elements by suspending the oxides in a fused salt melt, introducing a chlorinating agent into the melt at 700 DEG -800 DEG C. so that uranium oxides are selectively chlorinated to uranyl chloride and dissolve in the melt, and then filtering the melt.  The process may be used for treating uranium dioxide nuclear fuel or fertile material to remove plutonium, or for the separation of U-233 from irradiated thorium.  The fused salt may consist of alkali metal halides, for example the NaCl-KCl eutectic.  The chlorinating agent is preferably elemental chlorine or phosgene; other agents mentioned are sulphonyl chloride, phosphorus trichloride, and phosphorus pentachloride. After filtering out impurities, the uranyl chloride in the melt is reduced to uranium dioxide by electrolysis or by addition of metallic zinc or magnesium; the uranium dioxide is recovered by filtration.
