Patent DK-82088-A (DK)
Inventor: HOUCHIN MARTIN RICHARD
IPC: C01G25/02
Filed: 1988-02-17
Abstract: In the economic production of hydrolysed zirconiferous precipitate, hydrolysis is carried out by the addition of base to aqueous acidic zirconium sulphate solution, to lower the H<+> to and maintain within a pH range of 3 to 7, preferably within 4 to 6. The base may be selected from ammonia, basic ammonium salts, e.g., ammonia-buffered ammonium salts, an alkali metal hydroxide, carbonate or bicarbonate. Specific bases include ammonia and ammonium/sodium/potassium hydroxide, carbonate or bicarbonate, with particular preference for ammonia and ammonium/sodium hydroxide. The starting materials may be incorporated in batchwise or continuous fashion, batchwise by combining them in a body of water, suitable electrolyte or solvent with thorough continuous mixing or continuously by mixing them together in a flowing stream. An additive in the form of an inorganic stabiliser or an organic surfactant may also be included. Inorganic stabilisers may be selected from one or more of Y2O3, Ce2O3, Al2O3, MgO and CaO or precursors thereof. In the finishing stage, either further base may be added to lower residual sulphate content or acid added to remove acid-soluble impurities. The precipitated product is then separated, (e.g., by filtration), washed and calcined to give pure zirconia. High purity zirconia has particular application in the electronics industry and for the production of partially stabilised zirconia ceramics.

Title: Improvements in or relating to money boxes
IPC: A45C1/12
Filed: 1951-01-02
Abstract: 706,919. Money boxes. SANDERS, C. M. March 31. 1952 [Jan. 2, 1951], No. 126/51. Class 18 [Also in Group XXV] A money box ha: locking means re leasable only wher the coins in the box reach a certain height. The box com prises a body having a removable base 1 and fixed cover 7, the body having one or more pocket: 4 for coins. The base is locked in position by engagement of a column 28, secured to it, with an element 25 forming part of a rotatable spindle 19. Turning of the spindle 19 to release the base 1 is prevented by the engagement of tumbler elements 8 with notches in a disc 10 slidable on but not rotatable about the spindle 19. The elements 8 are free in holes in the cover 7 and depend loosely from a cap 9. When the cap 9 is pressed down against a spring 37, the elements 8 are lowered with it, as is the disc 10. If the coin pockets are full, however, the elements 8 cannot move downwardly so that the disc 10 is depressed clear of their shoulders and the spindle 19 may be turned. A tumbler (not shown) carried loosely in a bore in the body 2, falls into a hole in the disc 10. to prevent opening the box by turning it upside down to cause the elements 8 to fall clear of the disc. A tumbler (not shown) similar to an element 8 is secured to the body so that the disc 10 must be depressed below its shoulder, even though the elements 8 are raised. before the box can be opened. Shutters 33 close the coin slots 14 when the cap 9 is depressed and wires 16 roll across the slots when the box is tilted. Plates 40 form coin traps. Windows 11 permit viewing of the contents.

Title: Recovery of cadmium
Inventor: LUND ROBERT E
IPC: C01G11/00
Filed: 1957-01-07
Abstract: The ratio of water-soluble cadmium to zinc values is increased in dusts recovered in the heating of zinciferous materials, these dusts containing water-insoluble oxidic cadmium compounds and zinc sulphate, by heating the dust, at a temperature from 400-700 DEG  C., to form cadmium sulphate and zinc oxide.  If there is insufficient zinc sulphate to convert all the cadmium to sulphate, zinc sulphate may be added.  After this first heat treatment, the material may be heated to above 700 DEG  C. (decomposition temperature of zinc sulphate) and below 827 DEG  C. (decomposition temperature of cadmium sulphate) to convert any remaining zinc sulphate to the oxide.  The product may be leached to recover the cadmium sulphate.  Any ferric sulphate present in the original dust is converted to the oxide by the heating.  Copper, aluminium, and arsenic are also rendered insoluble.
