Title: Improved process for saponifying materials made from cellulose esters
IPC: D06P5/22
Filed: 1935-04-23
Abstract: Materials comprising cellulose esters are saponified by means of an alkaline agent in the presence of an organic base, or salt of such base, having pentavalent nitrogen, phosphorus, antimony, or arsenic, or tetravalent sulphur, and which contains a chain of at least four carbon atoms and is capable of being adsorbed by the materials. Examples of such bases or salts are dodecyltrimethylammonium bromide, octadecenyltrimethylammonium bromide, dodecylpyridinium sulphate, diethylbenzyl-dodecylammonium chloride, the addition product of dimethyl sulphate and naphthalene sulpho - N - b  - oxyethyl - N<1> - dimethyl - 1, 3-propylenediamine (obtained by reacting naphthalene-b -sulphochloride with N-b -oxyethyl-1-amino - 3 - dimethylaminopropane) p-methoxyphenylacetophenone - o  - trimethylammonium bromide (obtained by brominating p-acetoxyphenylacetophenone in acetic acid and allowing a solution of the product in dioxane to stand with two molecular proportions of trimethylamine until the product is soluble in water), methylethylcetylsulphonium methosulphate, cetyltrimethylphosphonium iodide, trimethyldodecylarsonium hydroxide (obtained by the action of dodecyl bromide on trimethylarsine and reacting the product with moist silver oxide) and trimethylundecyl stibonium chloride (obtained by reaction of undecyl chloride and trimethyl stibine.  The process is applicable in the superficial saponification of films; in the saponification of mixed fabrics from cellulose acetate artificial silk and regenerated artificial silk for the purpose of dyeing them in common by means of direct cotton dyestuffs for subsequent discharge printing; for grounding cellulose acetate fabrics with alkali naphthol or printing cellulose acetate fabrics with vat dyestuffs or mixtures of diazo-compounds and azo-compounds, wherein the printing paste must cause local saponification.  The threads may be treated with resists, e.g. sodium cresol sulphonate, advantageously in the presence of a protective colloid.  In examples: (1) a cellulose acetate fabric is saponified in the presence of dodecyltrimethylammonium bromide, and dyed with direct dyestuffs; (2) cellulose acetate fabric is saponified in the presence of para-ethoxyacetanilide-o -trimethylammonium bromide; (3) cellulose acetate fabric is saponified in presence of diethylbenzyl - dodecylammonium chloride; and (4) cellulose acetate filaments are treated during winding with a solution of trimethyldodecylammonium bromide and methyl glycol, spun with similar yarn prepared with olive oil, worked into a fabric, and dyed with direct dyestuffs.

Title: Method of and apparatus for manufacturing casts or blocks from soil, vegetable mould or like material
IPC: A01G9/10
Filed: 1952-05-16
Abstract: 719,961. Moulding seed casts. VRIJ, A. DE. May 16, 1952, No. 12412/52. Class 87 (2) A method of manufacturing casts or blocks from soil, vegetable mould or like material comprises feeding such material into an extruder comprising a casing with a worm conveyer wherein it is homogenized and from which it is driven out between the casing and a central core as a centrally perforated string which is subjected to periodical cutting parallel to the delivery end of the casing. The vegetable mould, to which fertilizer may be added, is placed in a hopper 5 and is homogenized as it is impelled by the worm 2 towards the open end of the casing 1. To produce seed casts which have bottoms the worm extension 6 stops short of the casing opening and the means for periodically cutting the extruded material comprises plates 10 which cover the opening during part of the rotation of a ring 7 in which they are mounted. Material is then forced between the end of the extension 6 and a plate 10, while other material surrounds the extension 6 which then acts as a core. As the plate moves away the material is forced through the opening, taking as its outside diameter the internal diameter of the casing, and is cut by the cutting edge 11 of the next plate 10 in the revolving ring 7. For bottomless seed casts the plates 10 may be dispensed with and radial cutting wires, mounted in the ring 7, may be used. For providing holes of different diameters in the seed casts the extensions 6 may be detachable and interchangeable. The part of the casing 1 beyond the worm 2 may also be detachable, allowing the use of extension pieces of different internal diameters and crosssections.

Title: Improvements in or relating to quick-cooking rice
IPC: A23L7/196
Filed: 1951-02-08
Abstract: A process for preparing quick cooking rice comprises subjecting brittle gelatinized rice grains having a moisture content of above 15 per cent and up to and including 20 per cent, which may be obtained by gelatinizing soaked grain having a moisture content from 25-30 per cent, to heat and moisture to increase the total moisture content by 1-2 per cent with the added moisture substantially confined to the surface layers of the grains to produce pliable rubbery sheaths surrounding relatively brittle cores and then subjecting the treated grains to mechanical compression, e.g. by passing through rollers and preferably compressing their thickness from 30-80 per cent of their pre-compression thickness so that the internal structure of the grains is modified without reducing the grains to a flaked condition. The rice may be gelatinized by soaking to raise the moisture content to about 35 per cent or above followed by treatment with substantially dry steam, soaked to a lower moisture content and treated with moist steam or it may be simply cooked in substantially the same manner as employed in the kitchen after which it is then dried to a moisture content of 10-20 per cent, preferably 10-14 per cent, and thereafter remoistened, e.g. with wet steam to an extent sufficient to raise the overall moisture content of the grains by 1-2 per cent and the bulk of the moisture thus added being concentrated in the outer portion of the grain.  After compression the rice grains are dried to a stable moisture content, e.g. 10-14 per cent, for packaging, storage and distribution.
