Title: Improved process for extracting tin
IPC: C22B25/06
Filed: 1922-06-15
Abstract: Tin is dissolved from tin-plate and other materials containing tin by treating with a solution of ferric or stannic chloride or both, with reduced pressure and with or without agitation.  The saturated solution is then divided so that the total tin in one part is equal to the tin that has been dissolved by the whole, and this part is then treated to recover the tin either as metal, oxide, or sulphide. The rest of the solution is oxidized in presence of hydrochloric acid and used again.  The precipitation of tin oxide may be effected with magnesia, the magnesium chloride being then heated to regenerate magnesia and obtain hydrochloric acid and chlorine which is used in the oxidation of the solution which is to be reused.  Specification 159,659 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) includes the treatment of the tin material with the solution with agitation without reduced pressure.  This subject-matter does not appear in the Specification as accepted.

Abstract: 871,435. Surgical swabs. KIMBERLYCLARK CORPORATION. May 30, 1958 [June 10, 1957 (2)], No. 17372/58. Class 81 (2). A reversible swab or dressing is made from a wad of absorbent material and at least one layer of loosely felted fibrous material of less capillarity than the main pad. Thus it may comprise a main absorbent pad 22 of fluff material and a control layer 24 consisting of a blend of wettable and non-wettable fibres such as to have the desired, relatively low capillarity. The whole swab is enclosed in a gauze or similar wrapper 20. With such a dressing, fluid reaching the lower face of the main pad 22 does not tend to pass into the layer 24, owing to the latter's lower capillarity, but tends to spread uniformly through the pad 22. If such a pad is used with the lower face against the body, the accumulation of fluid on the sheet 24 ultimately causes it to percolate through, whereupon it is readily absorbed by the pad 22. Because of this effect a pad may have a control layer on each face while, in further modifications, additional layers of crepe tissue may be placed outside such control layers and/or a spreader element of waxed tissue may be centrally placed in the assembly.
