Abstract: 600,263. Hydraulic machines. SPERRY GYROSCOPE CO., Inc. Feb. 22, 1945, No. 4525. Convention date, Feb. 22, 1944. [Class 69 (ii)] [Also in Group XXVIII] In a closed fluid circuit comprising a circulating pump such as a motor-driven blower 20, conduits 18, 19, and a fluid-driven or utilizing apparatus such as the housing 10 of a gyroscopic autopilot of an aircraft, where the fluid may actuate the gyroscope or prevent fogging of the housing windows leakage is made up by means which are normally ineffective but become operative in response to the absolute pressure in one of the conduits. The motor may be located in the casing of the blower, thus heating the circulating fluid. Leakage is made up by a diaphragm pump 28 which can be actuated through a bell-crank lever 30 by a cam 33 driven by the motor. The pivot of the crank is carried by an arm 34 one end of which is fixedly pivoted and the other end moved by a bellows 36 responsive to the pressure in the casing and conduit 18. When the pressure falls owing to .leakage, the point of engagement of crank 30 with the cam is moved from the centre and the cam operates the pump to draw in fluid from a container 24 which may contain a dust filter and a moistureremoving silica-gel filter. For cooling, the supply conduit 18 may be branched, one branch having cooling fins, and the proportions of fluid passing through the branches being regulated automatically by a thermally responsive gate 43.

Title: Separation of plutonium from neutron-irradiated uranium
IPC: C22B60/02
Filed: 1944-03-11
Abstract: 834,529. Separation of plutonium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 11, 1944 [April 3, 1943], No. 4577/44. Class 39(4). Plutonium is separated from an aqueous nitric acid solution of neutron-irradiated uranium, in which the plutonium is in its fluoride-insoluble (plutonous) state, by extraction with an organic solvent which extracts uranyl nitrate, leaving plutonous nitrate and fission products in the aqueous phase. The aqueous phase may then be oxidised and contacted again with the solvent which extracts both plutonium and any remaining uranium, most of the fission products again remaining in the aqueous phase. Agitation of this extract with water containing a reducing agent causes plutonium to pass into the water layer from which it may be precipitated, e.g. as fluoride, iodate, or hydroxide. Alternatively a reducing agent may be added to the solvent extract to precipitate the plutonium. The preferred solvent is diethyl ether, but others referred to are methyl ethyl ether, isopropyl ether, methyl ethyl ketone, nitropropane, nitrobutane, and a mixture of acetone and xylene. Suitable oxidising agents are listed, examples being sodium dichromate and chlorine. The reducing agent may be sulphur dioxide or hydrogen peroxide. To assist the extractions, soluble salts, for example lithium nitrate or aluminium nitrate, may be added to the aqueous solution. The Specification as open to inspection under Sect. 91 describes also the extraction with ether of an initial solution in which the plutonium is in the oxidised state ; both plutonium and uranium pass into the solvent layer which is shaken with water containing sulphur dioxide as a reducing agent to separate plutonium. This subject-matter does not appear in the Specification as accepted.

Filed: 1930-02-11
Abstract: <PICT:0343730/IV/1> An artificial silk cake removed from the collecting box is supported on a relatively large horizontal support; a strip of textile material is placed along the top outside surfaces of the cakes, and another strip along the lower inner surfaces.  The cake is then treated by causing water or other liquid to drip on to the upper strip of material.  The cake support may be a perforated bobbin of artificial resin, or of metal coated with a resistant enamel, the diameter of the bobbin being about two-thirds of the internal diameter of the cake, or three or more rods may be employed, so spaced that they support the upper part of the cake in such a manner that it more or less retains its circular shape.  The treating liquid may be allowed to drip from a perforated trough, and several bobbins with their distributing troughs may be placed vertically one above the other so that several cakes can be treated in succession with the same liquid. In the drawing, a slightly conical cake C is supported on a perforated bobbin B.  A strip of cloth E is placed along the top outside surface of the cake and a strip of cloth F is placed along the lower inner surface.  Water or other liquor supplied to a trough D drips on to the strip E and is distributed over the surface of the cake.  The strips E and F minimize any crossing of the threads during the treatment and ensure an even distribution of treating liquid.

Alternatively, the seal member may be mounted in front of a screwed ring so that unscrewing of the ring forces the seal member into closer sealing engagement with the wall of the housing.
Patent GB-415076-A (GB)
Title: Improvements in or relating to variable speed power transmission mechanism
IPC: F16H15/38
Filed: 1933-02-16
Abstract: 415,076. Variable-speed friction gearing ; lever linkages. CLOUDSLEY ENGINEERING CO., Ltd., 5, Chancery Lane, London, and HAYES, F. A., Middletown, New Jersey, U.S.A. Feb. 16, 1933, No. 4746. Convention date, March 4, 1932. Addition to 344,064. [Classes 80 (ii) and 80 (iii).] The parent Specification describes variable-speed gearing with toric discs and twin sets of precessional rollers in which the load is equalized between the rollers of each set by a freely-wabbling ring. The control of the speed is applied by turning the wabble ring 35 of the first set. This invention is to apply turning alone to the wabble ring 35, for controlling, without any radial forces. This is effected by a balanced linkage 164, 169, 165 all on one side of the driving-shaft 12 of the gearing. The gearing comprises two end toric discs on the shaft 12 of which one only, disc 10, is shown in Fig. 3. The gearing is non- epicyclic and the spiders 25 which support the two sets of rockers 28 of the twin sets of precessional rollers 18 are directly connected to the gear casing as described in Specification 392,589. The spiders 25 also support a sleeve 13<a> which forms a bearing for the driven double toric disc 15. The equalizing ring 35 of the first set is connected to a like ring, not shown, of the second set by a sleeve 13b which is free to wabble. Precession is initiated by rocking the rockers 28, Fig. 1, through fingers 34 which engage the ring 35, and the object is to control by applying a turning moment only to the ring 35. The ring 35 is connected by arms 36 to an outer wabble ring 37 which is carried by the upper ends of two swing links 164 which are connected at their lower ends by ball joints 168 to an H-shaped floating beam 169, Fig. 2, which is free to move up and down as well as to rock. The other limbs of the H are hinged at 167 to a balance beam 165 which can swing about a fixed pivot pin 166. The gearing is torque-responsive and the load reaction depresses the left arm of the beam 165 so that by resisting this depression by a spring 170, Fig. 1, the gearing is rendered automatic. The upper limit of the speed range is determined at will by a hand lever 176 in the path of the right arm of the beam 165 and lockable at 181. Overload depresses the left arm of the beam 165 far enough to strike a pin 171 which stops the engine by suitable means such as by breaking an ignition circuit at 173.
