Title: Manufacture of cellulose derivative emulsions and polishes
IPC: C09D101/12
Filed: 1950-06-05
Abstract: A cream or paste suitable for use as a polishing composition is obtained by adding a solution of a water-insoluble cellulose ester or ether in a solvent or solvent mixture, which is insoluble or only sparingly soluble in water, to a previously prepared "oil-in-water" type of emulsion, which is normally non-fluid or semi-fluid at room-temperature, and the non-aqueous phase of which consists of an unsaponified fatty acid, paraffin wax or like waxy substance dispersed without the use of an organic solvent, and maintaining the previously prepared emulsion in a fluid condition at a slightly raised temperature, not exceeding 30 DEG  C., during the operations of receiving and emulsifying the cellulose derivative solution.  An inorganic filler such as a silicic matting agent may be present in admixture with the waxy substance.  In an example, an aqueous solution of potassium carbonate is heated to 70 DEG  C. and poured into molten stearic acid with vigorous stirring.  Part of the acid is converted into soap which serves to emulsify the rest. The emulsion is cooled to 30 DEG  C. and then a solution of shredded cellulose acetate in methylene chloride and benzyl alcohol is added.  The mixture is stirred until the cellulose acetate solution is emulsified.  An emulsion of creamy consistency is obtained.  In another example, a molten mixture of stearic acid and paraffin wax is mixed with hot potassium carbonate solution and emulsified.  The emulsion is cooled to 30 DEG  C. and then a solution of cellulose acetate in methylene chloride and benzyl alcohol is added.  The emulsion obtained forms a firm paste when cooled.  It may be applied with a cloth to wood, linoleum, or other surfaces.  A polish having fire-proofing properties is obtained by using a mixture of stearic acid and a silicic matting agent such as diatomaceous earth instead of the mixture of stearic acid and paraffin wax.

Title: Improvements in or relating to woven textile fabrics
IPC: D03D23/00
Filed: 1927-03-08
Abstract: 291,859. Taylor, W. H., Ormrod, J., and Dawson, H. March 8, 1927. Figured fabrics such as quilts or covers are woven with warp threads W, which are all of the same count, but with a fine weft P<1> and a coarse weft P inserted by two shuttles. The figure is formed by floating the coarse weft under or over a ground or back comprising a plain weave formed by the other weft thread and the warp threads as shown by picks 2, 3, 6 and 7, in Fig. 1, so that the figure appears raised from the ground. The shedding is effected by two comber boards and one jacquard, in the case where the coarse weft is floated under the ground or back as shown, or two jacquards where it is floated over the ground &c. Where figuring is not taking place, each shed contains a pick of fine weft and a pick of coarse weft. Long floats of the figure are caught or picked under intermediate ends to prevent undue lengths of floating weft appearing loose on the cloth. Fach pick where stitching is being worked during the figuring is only stitched by one single end, although two ends are tied to one hook, the jacquard hooks being connected to mounting threads passing through the comber boards and connected to couplings in a special manner described.
