Title: Improvements relating to the recovery of uranium by ion-exchange
Inventor: ARDEN THOMAS VICTOR
IPC: C22B60/02
Filed: 1953-04-22
Abstract: Complex uranium anions are recovered from a resin which has been used to take up both uranium and iron as complex anions from solutions, by elution, after treating the resin with dilute sulphuric acid and/or a dilute solution of a neutral metallic sulphate to selectively remove the iron.  If a metallic sulphate is used, it is necessary to rinse out any excess before elution of the uranium.  The resins used are those containing secondary and/or tertiary amine groups with or without a smaller proportion of quaternary ammonium groups: they may e.g. contain diethylamine, dimethylamine or monoethylamine groups. Suitable sulphates are those of sodium, potassium or magnesium.  The process may be performed by passing the solution through the bed in the usual way.  In the example, a bed of resin was saturated with a solution containing uranyl sulphate and iron sulphate and eluted firstly with 0.001M H2SO4 and then with a solution containing 0.9M NH4NO3 and 0.1M HNO3. The uranium solution was precipitated with ammonia and ignited at 800 DEG C. to obtain a product containing over 92 per cent. of U3O8.  With 0.1M H2SO4 as the washing solution, 99.5 per cent.  U3O8 was obtained. Specifications 654,706 and 694,706 [both in Group IV(a)] are referred to.

Title: Nut threading machine
IPC: B23G1/20
Filed: 1953-04-22
Abstract: 724,589. Tapping. HOLZER, J. April 22, 1953 [April 26, 1952], No. 11131/53. Class 83 (3). A nut-threading machine comprises one or more reciprocating members 6 which are each spring-urged to feed a blank over an axially stationary tap 2, and a feeler 39 which initiates disengagement of the tapped blank and retraction of the member 6. In a six-spindle machine, each pocket formed in a head 7 receives a nut blank from a shoot 19 of a hopper 18 having an agitator 51. Each pocket is then closed by springs 16 as the member 6 is advanced by a spring 13. Each nut is threaded as it is advanced over the curved shank tap 2 by the spring 16. Advance of each member 6 releases the feeler 39, the feelers being secured to a common shaft 37 so that, when each nut is fully tapped, the feelers drop down together and allow a cutch 44 to engage. Engagement of the clutch causes rotation of the shaft 37 from a continuously-rotating motor 48, which also rotates a cam 49 actuating the agitator 51. The shaft 37 carries a cam 36 which, through linkage, actuates a common bar 26 engaging a projection 25 on each member 6 to withdraw it. After one revolution of the shaft, a cam 42 cooperates with a fixed pin 43 to disengage the clutch. The members 6 then advance again, each pocket having been held open by engagement of a lip 22 with the shoot 19. The heads 7 are replaceable according to the size of nut to be threaded.

Title: Transverse scale device for the precision reading of scales
IPC: G01B11/00
Filed: 1954-04-21
Abstract: 767,969. Machine-tool details. HEIDENHAIN, J., [trading as WENCZLER & HEIDENHAIN]. April 21, 1954 [April 21, 1953], No. 11584/54. Class 83 (3). [Also in Group XIX] A device for reading the position of e.g. the 100 graduation-line S of a scale, moving with the slide of a machine-tool, comprises, as in Fig. 2, an array of identical, equally spaced rectangles R, m+1 in each column, stepped in succeeding columns in a ratio 1/n. As shown, m=n=10 and the line S cuts the rectangle lying between the fifth and sixth space in the first column and lies most evenly between two rectangles in the fifth column so that the scale reading is 100.55. The scale graduation-lines S may be optically projected on to the device and if the width of the line S is suitably chosen with relation to the magnification ratio and length, along a column, of the rectangles and spaces, the accuracy of the reading may be increased. To determine the kth part of an m, nth part of a graduation, a series of vernier lines may be provided between the line S and in Fig. 5, where m=n=k=10, the image 165 S<SP>1</SP> cuts the rectangle between the second and third spaces in the first column, lies most evenly between two rectangles in the fifth column, and in the fifth column the image of the third vernier line R<SP>1</SP> lies most evenly between two rectangles so that the reading is 165.253. If the geometrical figures of the transverse scale are circles, the graduation-lines are in the form of rows of smaller circles and symmetry balancing is obtained by observing where a small circle is most nearly concentric with a larger one. In an alternative form the graduation-lines are stepped, instead of the rows of geometrical figures being stepped.

Abstract: 848,275. Gear gauging and sorting apparatus; indicating output of machines. NATIONAL BROACH & MACHINE CO. April 11, 1958, No. 11593/58. Classes 106 (2) and 106 (4). [Also in Group XXII] Gear gauging apparatus adapted to operate with a machine for finishing gears comprises means 10, 12, to gauge the finished size of the gear and the helix angle of its teeth, means for rejecting gears which are defective by reason of size or of helix angle errors, means for counting the rejected gears, and means for initiating arrest or adjustment of the finishing machine when a predetermined number of gears are rejected for the same error or when the total number of gears rejected for any error reaches at any instant a predetermined percentage of the total number of gears gauged up to that instant. Gears to be tested travel along a shoot 66 from the finishing machine (not shown) and mesh with a rotating master gear 10 and a master gear 12 fixed against rotation. The gear 12 is mounted on an arm 34, 36, pivoted about an axis 54 for movement in a vertical plane and also pivoted about an axis 38. Movement of the arm 36 about the axis 38 indicates whether the helix of the gear being tested is correct, displaced to the left, or to the right; similarly, movement in the vertical plane indicates whether the diameter of the gear is undersize, oversize, or within a specified tolerance range. If the gear is correct both as to helix angle and diameter, it moves on, after gauging, over a pair of trap doors 78, 80 on to a conveyer or receptacle (not shown). If the gear is undersize it is regarded as waste and drops through the trap door 80, opened by a solenoid B, into a receptacle or conveyer. If the gear is oversize, then regardless of its helix angle it is regarded as salvageable and is allowed to fall through the trap door 78 which is operated by a solenoid A. The pivotal movement of the arm 36 about the axis 38 allows the master gear 12 and the work gear to mesh to the full depth of their teeth and hence the gauging of the diameter is unaffected by variations in helix angle. An electromechanical circuit is described which acts to stop the gear-finishing machine should three consecutive gears exhibit the same fault or if a certain percentage of the gears produced is incorrect. Alternatively, the gear-finishing machine may be automatically adjusted if the faults are in the diameters of the gears (Group XXII). Electric circuits for carrying out these operations are described.
