Title: Improvements in ignition timing devices
IPC: F02P5/10
Filed: 1950-05-08
Abstract: 685,783. Interrupters. ETABLISSEMENTS DUCELLIER. May 8,1950 [May 16, 1949; May 2, 1950], No. 11459/50. Class 38 (v) [Also in Group XXVII] In an ignition. timing devise comprising a link 6 pivotally mounted on a base plate 4, a spring- loaded movable contactstud arm 8 pivotally mounted upon the link 6, a fixed contact-stud 15 mounted upon the base plate 4, and an interrupter actuating-cam 3 in operative contact with a follower 9 mounted on the arm 8, there is provided a member, such as rod 13, secured at one end to means responsive to induction-pipe pressure, for example a diaphragm, and at the other end to the link 6 so that during engine operation the diaphragm controls the position of the link 6 and hence the arm 8 whereby the angular position of the follower 9 is varied in accordance with induction-pipe pressure. The plate 4 carries a fixed pin 5 upon which is pivoted the link 6, the latter incorporating a stud 7 upon which is journalled the arm 8; the end of the link 6 remote from the pin 5 is pivotally connected to the rod 13 of the diaphragm, piston or capsule acted upon by the depression in the induction pipe. The fixed contact 15. has a rounded surface and a considerably larger area than contact 14 on arm 8 in order to permit freedom of movement of the latter during adjustment of the timing and the maintenance of a relatively constant contact gap. The distances between the axis of pin 5 and the centre of curvature of the fixed contact 15 and between the axis of stud 7 and the movable contact 14, and between the radius of curvature of the fixed contact 15 and the distance between the axis of pin 5 and stud 7 are equal so that the follower 9 is displaced curvilinearly upon movement of rod 13. Where the angular adjustment is small the surface of contact 15 may be flat. In a modification, the spring 11 which loads the arm 8 acts as an electrical conductor and is carried by the casing instead of the link; moreover the positions of pin 5 and stud 7 are interchanged whilst the rod 13 is housed at each end in a solid boss instead of being pivoted at these points. The timing adjustment effected by the device is additional to that made by the usual centrifugal means (not shown).

Title: Recovery of uranium from low grade uranium bearing ores
IPC: C22B60/02
Filed: 1957-04-09
Abstract: <PICT:0825100/III/1> Uranium values are recovered from a mixture containing free or combined aluminium, iron and uranium by chlorinating the mixture and passing the vapours in contact with molten alkali metal chloride to selectively deposit uranium chloride therein, and thereafter separating the uranium values from the alkali metal chloride.  The invention is particularly applicable to the recovery of uranium from low grade shales which are preferably heated to 450 DEG  to 800 DEG  C., to remove volatile organic components before reaction with a chlorinating agent at 600 DEG  to 1000 DEG  C. Suitable chlorinating agents are phosgene, carbon tetrachloride, chlorine and a mixture of chlorine and sulphur chloride; volatile matter is preferably removed from the shale prior to chlorination by retorting or roasting for example in a fluidized solid roaster. As shown in Fig. 1, shale is crushed and fed to a retort with steam or recycled combustion gases and heated at 450 DEG  to 800 DEG  C.; the combustion gases can be recycled.  The heated shale is then chlorinated preferably with chlorine diluted with dry nitrogen and the metal chloride stream is freed from entrained solids in a separator operating at 700 DEG  to 900 DEG  C.  The chloride stream is then passed to a molten alkali metal chloride maintained at 700 DEG  to 1000 DEG  C. whereby the uranium chloride is selectively extracted. Uranium values are recovered by cooling the alkali metal chloride bed, dissolving in water and acidifying the solution with nitric or sulphuric acid after which the uranium values may be extracted with a selective organic solvent such as benzylamine or diethyl ether.  Metal chlorides not extracted by the alkali metal chloride may be condensed at 100 DEG  to 300 DEG  C. to remove aluminium, ferric, and potassium chlorides, whilst leaving silicon and titanium chloride with sulphur chlorides and chlorine in the vapour stream. Chlorine and sulphur chlorides are separated and recycled to the chlorination zone.  The condensed aluminium, ferric, and potassium chloride mixture is vaporized and the resulting chloride stream may be passed through ferric oxide to convert the aluminium chloride to a commercial grade alumina.  The resulting ferric chloride may be reacted with oxygen at 1000 DEG  C. for form ferric oxide and chlorine, the latter being recycled.  Alternatively the chloride stream leaving the molten alkali metal chloride which has absorbed the uranium may be contacted with further alkali metal chlorides, such as potassium, at 500 DEG  to 650 DEG  C., whereby iron and aluminium chlorides are retained in the alkali metal chloride. The resulting mass may be heated in an oxidizing atmosphere to form chlorine and a mixture of ferric and aluminium oxides which may be separated by known means.

Abstract: 680,668. Rotary pressure exchangers. JENDRASSIK, G. May 7, 1951 [May 9, 1950], No. 11573/50. Class 8 (i). In a rotary pressureexchanger having a ring of cells 5 and pressure exchange ducts for the transfer gas, the ducts comprise separate passages 9 each having a kinetic-energy storing portion 11. 11<SP>1</SP> along which the cross-sectional area is substantially constant which portion is so dimensioned that in operation the flow of transfer gas persists after the pressure in the interconnected cells has been equalised whereby the pressure in the cell located downstream in relation to such flow becomes higher than that in the cell located upstream. The transfer gas flows from an expansion cell through a convergent portion 13, the energy storing portion 11, a diffuser 12, a duct 9a, another convergent portion 13<SP>1</SP>, the second energy storing portion 11<SP>1</SP>, and a further diffuser 12' into a compression cell. A further energy storing portion may be used instead of the duct 9a. The invention is applicable to exchangers having a single rotor 1 or to one having two or more contrarotating rotors with or without intermediate stationary partitions. The ends of the passages may be curved in a circumferential direction to impart to the gas a peripheral velocity or to avoid shock. The cells may be formed by helicoidal partitions in the rotor which may be so shaped that the scavenging gases entering or leaving the cells produce a turbine effect for driving the rotor. Guide vanes may also be provided on the scavenging ducts or on the rotor for directing the scavenging flow. Specification 290,669. [Class 8 (i)], is referred to in the Provisional Specification.
