Patent GB-867057-A (GB)
Title: Method for purifying uranium-base material
IPC: G21C19/48
Filed: 1959-05-07
Abstract: Uranium-base material contaminated with plutonium and other fission products is purified by dissolving it in zinc or zincmagnesium alloy and increasing the magnesium concentration of the solvent to precipitate the uranium which is then separated from the solvent. The nuclear material may be either metallic p  uranium or a uranium compound, e.g. UO2.  In the former case, the uranium is dissolved in zinc and magnesium is added directly to the solution in sufficient quantity to form the zinc-magnesium eutectic and cause precipitation of the pure uranium.  In the latter case, the uranium compound is dissolved in a zinc-magnesium alloy containing at least 6% of magnesium and the magnesium concentration of the solvent is increased, either by adding magnesium or by distilling off some zinc, until the solvent has eutectic proportions when the pure uranium is again precipitated.  In both cases after dissolution of the nuclear material in the solvent, the solution may be cooled to precipitate intermetallic compounds of uranium, plutonium and zinc and these intermetallic compounds melted with magnesium to precipitate uranium. Specification 833,153 is referred to.

Filed: 1956-05-22
Abstract: 793,404. Globular powders. OLIN MATHIESON CHEMICAL CORPORATION. May 22, 1956, No. 15857/56. Class 9(2) A process for the manufacture of globular powder by dissolving a smokeless powder base in a solvent to form a lacquer and the lacquer is subdivided and suspended in a suspending medium immiscible with the lacquer, is characterized by fortifying the suspending medium with the solvent before the suspending medium contacts the lacquer. The amount of solvent used in fortifying the suspending medium is ascertained by taking samples of both the lacquer and suspending medium, adding to the medium a small amount, say 2 per cent, of the solvent used in making the lacquer, mixing the lacquer with the fortified sample and analyzing the suspending medium to obtain the solvent content. This is repeated with increasing amounts of fortifying solvent until the amount added is equal to the solvent content of the suspending medium after mixing with the lacquer. In an example a nitrocelluloseethyl acetate lacquer containing chalk and diphenylamine is subdivided and suspended in a water medium containing gum arabic and the quantity of ethyl acetate as determined by test. U.S.A. Specification 2,027,114 is referred to.

Title: Improvements in or relating to steering mechanism for motor road vehicles
IPC: B62D11/08
Filed: 1943-10-01
Abstract: 572,316. Motor-vehicle driving and steering gear. AUTOMOTIVE PRODUCTS CO., Ltd., and GATES, G. R. G. Oct. 1, 1943, No. 16137. [Classes 79 (ii) and 79 (iii)] In a vehicle having a castor wheel or wheels 13a remote from a pair of co-axial driving wheels 11a, 12a and in which steering is effected by driving the wheels 11a, 12a positively at different speeds, the driving mechanism comprises two disengageable main clutches 34, 35 between the engine and the driving wheels, a differential gear 44 having two of its members connected respectively with the driving wheels, and a normally disengaged auxiliary clutch or clutches 47, 48 connected between the engine and the third member of the differential gear, the controlling mechanism being such as to release either one of the main clutches and simultaneously engage the auxiliary clutch or clutches. The engine and driving wheels may be at the front and the castor wheels at the rear, or the castor wheels 13a may be at the front as shown in Fig. 2 and the driving wheels at the rear. In the latter case the engine may be at the front at 19 or at the rear at 19a, the drive in either case being through a gearbox 18. The castor wheel stub axles are preferably connected by a track rod 26a. The driving gear for the wheel axles 16, 17, shown in Fig. 3, is similar to the driving gear for endless tracks shown in Fig. 3 of Specification 563,339 with the hydraulic control shown in Fig. 1 of that Specification, the main difference being that in the present case there are two gear trains 50, 49 and 52, 51 between the shaft 33 and the differential casing 44 controlled by two simultaneously-operated clutches 47, 48, instead of the single gear train 88, 91 and single clutch 87 of the above-mentioned Specification. Normally the engine-shaft 28 and change-speed gear 29 drive the wheel axles 16, 17 at the same speed through clutches 34, 35. Steering is effected by rotation of a hand wheel 63, a cam 64 on which operates an hydraulic master cylinder 70 to energise a servo-cylinder 74 to supply liquid to pipes 75, 76, and thereby (1) disconnect one of the clutches 34, 35, and (2) engage the clutches 47, 48 so that the disconnected shaft 16 or 17 is now positively driven, at a different rate to the other shaft 17 or 16, from the shaft 33 through the gears 49-52, clutches 47, 48, differential gear 44, differential shafts 42 or 43, and gearing 59, 60 or 61, 62. The servo-cylinder 74 is energised as described in Specification 525,415, [Group XXXIV]. The usual brake pedal (not shown) may be arranged to act on the master cylinder 70, so that when the brakes are applied the .clutches 47, 48 are engaged and provide an additional braking effect, since the main clutches 34 and 35 are still engaged.

Title: Improvements in or relating to apparatus for measuring the rate of flow of fluids
IPC: G01F1/20
Filed: 1946-05-28
Abstract: 613,478. Fluid flowmeters. POSTLETHWAITE, F. May 28, 1946, No. 16176. [Class 69 (i)] In a flowmeter of the orifice plate type, the plate 10 is held in the path of fluid flow by a pliable diaphragm 11 that prevents rotation or movement transverse to, but not parallel to, the fluid flow. Axial movement of the plate is restrained by tensioned grids of resistance wire 12, 13, one or two of which are secured to either one or both sides of the plate and the casing and form arms of a bridge circuit so that movement of the plate and consequent variation of strain on the grids upsets the balance of the bridge, causing an indication to be given on a calibrated ammeter. In a modified form the diaphragm is of springy material and the resistance grids are replaced by inductance coils, each surrounded by a, soft-iron magnetic circuit which is completed by soft-iron pieces on the orifice plate, movement of which causes variations in the air gap of the circuit.
