Title: Improvements in materials for the treatment of leather
IPC: C09D13/00
Filed: 1951-12-14
Abstract: Material for reconditioning and preserving leather having a rough surface is made by mixing together an adhesive, a pigment in powder form and a wax-like or greasy material such as is commonly used as a cosmetic ingredient, drying the mixture and granulating it, and then compressing the granulated material into the form of bars, blocks or tablets.  In an example, 600 parts by weight of a pigment, such as lamp-black, and 330 parts of a 5 per cent. solution of dextrin in water are kneaded together.  In a separate steam-heated agitator, 25 parts of stearin are heated to 90 DEG  C., and when molten mixed with 25 parts of technical glycerine and 20 parts a fatty alcohol sulphonate, such as sulphoricinolic acid. The molten mixture is then cooled to 30 DEG  C. and added to the remaining material, and the whole kneaded together for about one hour.  It is then dried for about 12 hours at 40 DEG  C., granulated, and shaped to tablets, blocks or bars in a compressing machine. The stearin may be replaced by other wax-like materials and the fatty alcohol sulphonate by other emulsifying agents.

Patent GB-393474-A (GB)
Title: Improvements in or relating to pigments
IPC: C09C1/00
Filed: 1932-10-26
Abstract: Pigments are obtained by heating together oxygen-containing compounds of titanium, antimony, and chromium, in the presence of an element which is electropositive to the other three constituent elements at high temperatures, i.e. an element which combines as a base with the other constituents.  The products are insoluble in water, acids, and alkalis, and inert to most chemical reagents at high temperatures. They have high opacity and covering power.  In colour they range from light yellow through orange and brown to olive.  They may be used in the manufacture of pottery, paints, cements, and rubber articles. Titanium dioxide, rutile, and titanium lithopone may be employed as sources of titanium; antimony may be introduced as the trioxide, pentoxide, tetroxide, or as antimonite or antimonate.  Chromium may be introduced as chromium trioxide, chromic oxide, chromates, or dichromates.  The electropositive element employed is ordinarily sodium or potassium, but other elements such as calcium, strontium, barium, magnesium, aluminium, zinc, tin, silver, lead, nickel, cobalt, lanthanum, and cadmium may be used.  In the ceramic industry where the clay contains sodium or calcium, this may constitute the source of the electropositive element.  Preferably, the ingredients are mixed in such proportions that the atomic ratios of chromium to antimony and of chromium to titanium are not greater than unity, and that the ratio of the weight of chromium to that of the electropositive element is not greater than the ratio of the atomic weight of chromium to twice the equivalent weight of the electropositive element.  The pigment may be made by mixing the constituents intimately and then calcining the mixture in an oxidizing atmosphere.  Intimate mixing is facilitated by mixing with water.  The temperature at which the mixture is calcined is preferably above 800 DEG  C.  One of the components may be mixed with ceramic raw material which is then formed into the desired article, fired, dipped into a suspension containing the remainder of the pigment ingredients, and again fired.  If desired, all the ingredients may be mixed with the ceramic material which is then formed into tableware, fired, coated with transparent glaze, and again fired.  Alternatively, the pigment may be mixed with a suspension of ceramic material and applied as a coating on a coloured or uncoloured body.  In examples, the following mixtures are specified:--titanium dioxide, antimony trioxide, chromic acid, and caustic soda; titanium dioxide, sodium antimonate, and chromic acid; magnesium carbonate, stannic oxide, strontium carbonate, cadmium oxide, nickel carbonate, aluminium oxide, sodium silicate, kaolin, or feldspar, and titanium dioxide, antimony trioxide, and chromic acid; lead chromate, titanium dioxide, and antimony trioxide.
