Title: Improvements relating to the recovery of uranium by ion exchange
Inventor: NOLAN JOHN DEVEREAUX
IPC: C22B60/02
Filed: 1956-07-02
Abstract: Uranium absorbed as an anionic complex, in particular UO2(SO4)34- and UO2(CO3)34-, on an anion exchange resin arranged as a bed, is recovered by precipitating the uranium in the bed by reaction with an alkaline solution, such as a solution of sodium hydroxide or ammonia passed through the bed, followed by removal of the precipitate, conveniently by the passage through the bed of a solution which dissolves the precipitate and from which the metal is at the most only slightly reabsorbed. Solutions of nitric or hydrochloric acid are suitable.  A suitable sodium hydroxide concentration is 0.5N. The completion of the precipitation reaction is indicated by the emergence of alkaline liquor from the bed.  No excess sodium hydroxide is required.  The precipitate may now be extracted from the resin by dissolving it out with 3 to 4 bed volumes of N nitric acid. The uranium may be recovered from this solution by precipitation with an alkali.

Abstract: 621,752. Cathode-ray oscillographs. SCOLES, G. J., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. July 9, 1946, No. 20505. [Class 37] [Also in Groups XXXVIII and XL (b)] To investigate a cycle of information, a time base synchronous therewith renders apparatus operative at selected positions along the time base so that information occurring at the time instants corresponding to the selected positions may be indicated for recording. The cycle of information a, Fig. 1, comprises e.g. six pulses 1 ... 6, whose magnitudes correspond to six items ; a synchronising pulse b is used at the receiver to produce a time base oscillation c at A, Fig. 2, which is applied to devices B1 ... B6 which produce trigger pulses at different levels of the time base ; thus, e.g. as the time base attains the level X, X<SP>1</SP>, Fig. 1, device B3, Fig. 2 produces a trigger pulse d, Fig. 1 ; these trigger pulses are applied to render cathode-ray tubes C1, C2, C3, Fig. 2, operative, so that information pulse 1, Fig. 1, is shown on C1, information pulse 2 on C2, information pulses 2, 3 and 4 on tube C3 simultaneously, while the trigger pulse from B6 is shown as controlling a gating circuit 6 to allow only information pulse 6 to actuate a meter R. A photographic record on a moving film may be made of the cathode-ray traces, and where more than one trace occurs on the same tube, they may be by switching off the trigger devices B1 ... B6 in a known sequence to produce gaps in the traces. Further time bases may be applied to the cathode-ray tubes to displace consecutive signals of the same item. Several items of information may be combined, e.g. added, for display on a single tube.

Title: Improvements in or relating to cutlery grinding machines
IPC: B24B19/00
Filed: 1921-08-05
Abstract: 189,838. Hemming, F. P., and Hemming, C. H. Aug. 5, 1921. Cutting-edges, shaping and treating.-A machine for grinding cutlery comprises a cup-shaped emery wheel 6, Fig. 1, and a reciprocating plate 20, to which the work is attached by a holder 29' and which is mounted on a carriage 10 pivotally movable towards the grinder against the action of a spring 68. Means are provided to locate positively the shoulder of the blade being ground with respect to the corner of the grinder at the termination of the idle travel of the plate 20. The grinder 6 is rotatable in standards 4 adjustable along a bed 1 by means of a screw 3. A plate 8 adjustably secured at any angle on the bed 1 has a stud 12, on which is pivoted the carriage 10. A shaft 15 having a screw-thread 16, Fig. 4, is journaled in the carriage 10 and carries driving and idle pulleys 17, 17a. The pulley 17 has an arm 37, which is journaled upon the shaft 15 and carries planetary pinions 43, 45 fixed on short rods 42 journaled therein. The pinions 43 mesh with a gear 38 fast on the shaft 15, and the pinions 45, which each have one tooth less than the pinions 43, mesh with a gear 39 integral with a clutch-sleeve 40 journaled on the shaft 15. When the sleeve 40 is moved by a lever 52 so that pins 47 thereon engage the arm 37, the shaft 15 rotates with the pulley 17, whereas, when the sleeve is moved so that pins 49 thereon engage a stationary pin 50, the shaft 15 has a slow reverse motion imparted to it from the pulley 17. A nut 18 on the screw 16 has a lug 19, which contacts with either of two rods 21, 23, Fig. 8, adjustably mounted on the plate 20, and thereby reciprocates the plate. On its idle travel, the plate 20 moves till it is arrested by a stop on the carriage to position the shoulder of the blade relatively to the grinder. The nut 18, however, travels further inwards, compressing a spring 25 surrounding the rod 23, thereby compensating for any lost motion, until a trip 62 on a bracket 30 secured to the nut contacts with an adjustable stop 63 on a shipper-rod 54 and moves the lever 52 to start the slow outward travel of the nut. For the first part of this travel, the plate 10 is stationary and a roller 34 carried by a lever 31 pivoted to the bracket 30 contacts with an incline of a former 35 to move the carriage 10 about its pivot 12 towards the grinder. When the lug 19 contacts with the rod 21, the plate 20 commences its outward travel, the roller 34 then being on a,straight part of the former 35. Outward movement continues till the trip 62 contacts with a second stop 65 upon the rod 54 and again shifts the lever 52. Just prior to this contact, a rod 66 on the carriage engages the lever 31, which it tilts so that the carriage may move away from the grinder.

[Also in Group XXVII] To enable an exhaust gas turbocharger 10, Fig. 1, to supply a sufficient air charge to a two-stroke engine cylinder 1 at all loads, the pressure pulses leaving the engine exhaust orifice 2 are divided into portions which travel different distances to the turbo charger 10 so that the pulses are in effect increased in frequency and diminished in amplitude. As shown, a branch exhaust passage 6 is provided, from the closed end 9 of which the pulses are reflected. The manner in which the invention also produces lowered pressure at the orifice 2 during scavenging and increased pressure at the instant of charging is described in detail. In Fig. 3 (not shown), an elongated branch passage connects to the turbo charger 10 independently of the main passage 5. In Fig. 9 (not shown), the turbo charger 10 is connected into a main dead-end exhaust passage close to the orifice 2. In Fig. 11, when one orifice 2 of a three-cylinder engine is open, the orifices of the other cylinders are closed and the duets 26 therefrom to a common exhaust passage 5b act as reflecting passages. A reflecting passage 35, Fig. 13, may surround the portion of the exhaust passage upstream (or downstream) of its junction therewith. Fig. 17 shows groups of three cylinders each connected to a common exhaust passage 5c by ducts 3b rendered of suitable length by having helical portions in a common pipe 3c. The invention is applicable to engines having piston controlled ports and to free piston and crank-shaft gas generators powering turbines. More than one exhaust system per cylinder may be provided.

Abstract: 382,311. Washing granular materials; amalgamating. COBBE, H. N. G., 39, Victoria Street, London. July 24, 1931, No. 21117. [Class 82 (ii).] Values are recovered from alluvial deposits by passing the material with a stream of water down an inclined sluice, the heavy values sinking into the interstices of a screen or the like travelling downwardly along the bottom of the sluice and over one or more openings near the lower end of the sluice into which the values fall. To regulate the size of the values passing through the openings, the openings may be covered by perforated plates or screens or an additional travelling screen with interstices of the required dimensions may be superimposed on the main travelling screen. The upper run of an endless chain carpet b passing round rollers c, d, e moves downwardly along the bottom of an inclined sluice a to which alluvial deposit and water are supplied by a shoot l. The values are deposited in the interstices of the carpet and are washed through openings h near the lower end of the sluice into hutches i with overflows k and discharge passages j which may be lateral as shown or vertical. To assist in breaking up lumps of clayey material flexible mats, preferably chain mats o extending laterally across the sluice are suspended from bars n carried by a framework q which is reciprocated longitudinally. To recover any values which have not entered the interstices of the screen the material discharged at m at the lower end of the sluice may be passed down an inclined trough having obstructions to retain the values. Amalgamation may be practised in the sluice, the hutches, or the inclined trough.
