Abstract: 708,190. Photographic roll-film developing apparatus. KEHR, W., and LESJAK, M., and STRAUSS. R. April 17. 1951 [May 11, 1950], No. 9000/51. Class 98(2) A daylight developing tank for roll films with protective paper backing strips, in which the exposed film is led into the spiral grooves of two oppositely placed spool discs by a strap having a film holding clip and secured to the core of the externally rotatable spool, also comprises means for holding the clip fast within. the tank and open to receive the film on rotation of the spool by pulling on the backing strip, a spring stripping member adapted to bear on the periphery of the film on its spool and on rotation of said spool to strip the film end from off the film roll so that it is brought between the jaws of the clip, manually operable means extending outside the tank for closing said clip to grip the film, and means manually operable from the exterior of the tank to release said clip holding means to allow the film to be wound into the tank. As shown, the clip on the band secured to the developing spool in the housing 1 comprises a member 8 on which is pivoted a jaw 8a. A projection 8b on the clip can be held against a wall 2a of the film spool chamber 2 by the cranked portion 11a of a rod 11 rotatable by an external handle which may be frictionally locked in the holding position against a fixed pin. The film spool is placed in resilient clips 12 in the chamber 2 where a spring-urged pivoted guide plate 5 engages the convolutions to prevent accidental unwinding, the leading end of the backing paper 6 being placed over the guide plate. The tank is then closed by the cover plate 3 and the backing paper is withdrawn, feeding the film end 7a into the jaws of the clip which is provided with a stripper plate 8c bearing against the spool. When the film is located in the clip as indicated by increased resistance to withdrawal of the backing paper, a plunger 14 in the cover 3 is depressed against spring action to close the clip which is then freed from the wall 2a by releasing the rod 11 so that the film may be wound into the developing spool. Instead of a plunger, a rotatable rod having a cranked or other projecting- portion may be used to close the clip 8.

Title: Improvements in or relating to method of forming coated pharmaceutical pellets
Inventor: MACDONNELL DONALD RICHARD
Filed: 1953-04-01
Abstract: In the production of sustained release pharmaceutical pellets, substantially spherical innocuous cores, e.g. of sugar, synthetic resin or nitrocellulose, or naturally-occurring seeds, are coated with a medicament, the cores are subdivided into groups, each group is provided with a slowly digestible coating to produce pellets of 0,1-2 mm. diameter to provide different times of release of the medicament on ingestion, and the pellets are combined e.g. by enclosure in a gelatin capsule, if desired with uncoated pellets. The cores are first wetted in a coating pan with gelatin &c.-sugar solution, and sprinkled with medicament, the operation being repeated as necessary; alternatively, the adhesive solution may contain dissolved or suspended medicament. The time delay material may be applied as a solution in various specified organic solvents of glyceryl monostearate and a wax, beeswax being preferred, or wax-like substances such as chlolesterol.  Fatty acids and alcohols may be used in place of glyceryl monostearate.  The various delay times may be provided by varying the thickness of the coatings, or by using different coating materials.  Medicaments specified are salts of racemic and dextro-amphetamine, racemic and dextro-desoxyephedrine, and 2-amino-1-(4 methylphenyl)-propane sulphate, or potassium iodide. The medicament may be extended with calcium sulphate dehydrate, starch, acacia.  Specifications 523,594, as open to inspection under Sect. 91, and 715,305 are referred to.

Title: Improvements in the electrolytic treatment of ores containing zinc and other metals
IPC: C25C1/16
Filed: 1920-04-01
Abstract: A precipitate obtained by adding zinc dust, with or without a copper salt, to sulphate solutions prepared from ores containing zinc and cadmium, with or without copper and cobalt, is treated for the recovery of cadmium, zinc, and, if present, copper, in the following manner.  If substantially free from cobalt, the precipitate is oxidized and leached with sufficient dilute sulphuric acid to dissolve a maximum of zinc and cadmium and a minimum of copper.  From the residue the copper is recovered by smelting or otherwise. Alternatively, the precipitate, oxidation of which is guarded against, may be leached with sufficient acid to dissolve the zinc, the residue being then oxidized and further treated to dissolve the cadmium.  In either case, the solution containing the cadmium is treated with zinc dust in quantity insufficient for complete precipitation of the cadmium, which is thus obtained free from zinc. In this treatment, the solution should be slightly acid and air should be excluded as much as possible; about 1/2 gr. of cadmium per litre should remain after precipitation.  A further treatment of the solution in a second vat with excess of zinc, and preferably in the presence of about 1/2 gr. of copper per litre, gives a zinc solution which is added to the purified ore solution, and a precipitate which can be used again in the first vat.  The precipitated cadmium is roasted and dissolved in dilute sulphuric acid or spent electrolyte. Copper is removed by excess of the cadmium precipitate, metallic cadmium, or cadmium oxide, and the solution, then containing about 100 gr. cadmium per litre, is electrolyzed.  After electrolysis, the solution should contain 60 gr. of acid per litre.  An alternative method of separating the zinc from the cadmium consists in agitating the solution with zinc oxide or hydrate at 60 DEG  C. for some time, and then cooling to 35 DEG  C. so as to precipitate the zinc as basic sulphate.  When the original precipitate contains cobalt, it is oxidized and leached with zinc sulphate solution or just sufficient dilute sulphuric acid to dissolve out most of the cadmium and cobalt, and the residue is then treated as in the first case.  The solution of cadmium and cobalt is treated with zinc dust as described above so as to obtain zinc-free cadmium, which is added to that obtained from the residue above mentioned, and a solution of zinc and cobalt, from which a pigment may be prepared, for instance by adding sodium carbonate and drying and heating the precipitate.
