Title: Improvements in or relating to the preparation of argillaceous material for use in the manufacture of pottery, glazes, enamels, glassware and the like
IPC: C04B33/04
Filed: 1943-12-10
Abstract: An argillaceous material for use in the manufacture of pottery, glazes, enamels, glassware and the like is rendered filterable for the removal of impurities by making a suspension or slurry of finely-divided clay and finely-divided silica, preferably the waste sand from the grinding of plate glass.  The argillaceous material, e.g. a highly-plastic ball clay, may first be mixed with an excess of water and passed through a screen to remove coarse foreign bodies, and is then mixed with dried or undried waste grinding sand, 20-60 per cent of the dry materials being ball clay.  The sand may have been previously treated magnetically or with acids for the removal of iron, or, alternatively, the mixture may first be passed through a magnetic separator and then treated with a 1 1/2 -5 per cent solution of hydrochloric or sulphuric acid to remove the iron, titanium and other impurities. The nascent hydrogen reduces any of the higher oxides present and so facilitates removal; alternatively, other reducing-agents, e.g. oxalic, hyposulphurous, or hypochlorous acid, sulphur dioxide, zinc, sodium, or calcium hyposulphite, or sodium or calcium hypochlorite may be added.  After washing to remove soluble materials, the suspension is filtered.  The silica will replace the quartz or flint in the pottery mix and any glass present in p  the sand will serve as a flux and replace some or all of the felspar. According to examples: (a) a pottery mix consists of 67 parts of a 40 : 60 ball clay-waste sand mixture, 28 parts of kaolin and 5 parts of felspar, and (b) a glass mix consists of 1000 parts of 90 : 10 waste sand-clay mix, 166 parts of dolomite, 282 parts of soda ash and 11 parts of salt cake.

Title: Improvements in or relating to the production of goods of or containing rubber
IPC: C08J5/02
Filed: 1931-07-23
Abstract: In the manufacture of rubber goods by deposition of rubber on a former from an aqueous dispersion, in which the deposition is effected by application of a rubber coagulant to the base, the thickness of the film is varied over the article by the application of a film of varying thickness or concentration, or both, to the base.  The coagulant may be applied to portions only of the base.  To produce a glove having a thick palm, a porcelain form is coated on the palm with calcium nitrate dissolved in acetone.  When the solvent has evaporated, the form is dipped into a dispersion, and rubber is deposited on the palm.  The form is then dipped in coagulant, dried, and immersed in latex for ten minutes.  Alternatively, the form may be dipped in coagulant, dried, a second film of the same or another coagulant applied where required, and the deposition effected in one dipping.  In sandblasting glass &c., parts to be protected are coated with coagulant, and rubber is deposited on these parts, while the remainder is coated with liquid latex which can be easily removed. If it is desired to provide a permanent coating of rubber, e.g. in a rack for supporting articles to be electroplated, an adhesive such as a solution of a rubber isomer as described in Specification 249,172*, [Class 70, Indiarubber &c.], may be applied to the former, before, or with the coagulant.  Patterns, letters, &c. may be produced on paper, wood, &c. by printing with a thick rubber cement containing 5 per cent of acetic acid, and immersing in latex.  The latex is washed from the untreated surfaces with weak soap and ammonia solutions. For providing rubber articles with raised lettering, a sheet of paper is printed with coagulant such as a solution of calcium nitrate in acetone or methanol, the sheet is immersed in latex, and when sufficient rubber is deposited thereon, is used as a transfer.
