Title: An improved process for producing a composition adapted for coating or impregnating fabric
IPC: D06N5/00
Filed: 1929-08-20
Abstract: 338,538. Antal, L. d'. Oct. 19. 1928, [Convention date]. Fatty oils, oxidized.-A material suitable for coating or impregnating jute bags or other fabric is obtained by oxidizing a vegetable drying oil or a mixture of such oils by treating at 180-200‹ C. and over with acid sludge from oil refining. Resinous or asphaltic substances with or without siccatives may be mixed with the oil, and mineral oils may be added during or after oxidation. The oil resin mixture is heated above 180-200‹ C. before the acid sludge is added, and the reaction continues until a homogeneous foamless mass is obtained. In one method of working, the amount of sludge is insufficient for complete oxidation, and the impregnated fabrics prepared from the product are dried in heated air to complete the oxidation. Vegetable oils specified are linseed oil and sunflower oil. The oxidized oil is of soft rubber-like consistency. It may be rolled in liquid or plastic condition on one side of a fabric, for making bags lined on the inside only; or the fabric may be impregnated in any known manner, to form a linoleum, a proofed jute or other fabric. The Specification as open to inspection under Sect. 91 (3) (a) comprises also treating the oils, which may include castor oil, by melting or heating them with substances containing the SO4 radical. This subject-matter does not appear in the Specification as accepted.

Patent GB-1055424-A (GB)
Title: Process for the manufacture of puff spray-dried milk products
IPC: B01D1/18
Filed: 1963-07-03
Abstract: Puff spray-dried, readily dispersible, lacteal powders are produced from lacteal materials such as whole milk, skim milk, butter milk, cream, chocolate milk and sweet or sour whey, by heating the material to a temperature and for a time sufficient at least to pasteurize it, concentrating the pasturized liquid (usually up to about 65% solids content), and spray-drying immediately following the injection of an innocuous relatively-insoluble compressed gas, all in a continuous process. The material may be concentrated to as high a solids content as possible provided the flowability thereof is maintained.  The concentrate, at a temperature designed to maintain its flowability until spray-dried, may be seeded with lactose or lactose containing material.  According to an Example, skim milk heated in a heat exchanger to 165 DEG F. was conducted through an evaporator of the falling film type, the time in transit being 15-20 seconds.  The concentrate containing 25% solids content, was further concentrated to 52% solids content in a second effect.  The first portion of this latter concentrate was puff spray-dried using a 0.043 inch nozzle and drying air at 270 DEG F. Nitrogen at a pressure in slight excess of the hydraulic pressure (1800 lbs. per sq. in. gauge) was injected into the concentrated fluid line immediately upstream of the nozzle at the rate of 2 standard cubic feet per 1.5 U.S.A. gallons of concentrate.  The powder obtained had a moisture content of 3.6%, a bulk density 0.37 and a dispersibility in chilled water of 94.8%; 4% of the lactose was in the crystalline a -form.  The second portion of the concentrate was seeded with a cold slurry of 325 mesh lactose at the rate of 100 grams in 100 lbs. of concentrate, was stirred for 5 to 10 minutes and was then puff spray-dried as above, giving a product containing 8% of lactose in the a -hydrate form.  A third portion was processed in the same way as the second except that it was stirred 30 to 35 minutes after seeding; 20% of the lactose was in the a -hydrate form.  According to other embodiments, (a) the nitrogen was injected into the concentrate at the rate of 1.5 standard cubic feet per 1.5 gallons of concentrate, (b) the forced crystalization engendered by the seeding was continued for one hour, (c) a concentrate containing 60% solids content was spray-dried through a 0.050 inch nozzle.  Seeding is conducted at the optimum temperature in the range 75 DEG -105 DEG F., preferably 80 DEG -100 DEG F., for obtaining the maximum rate of crystallization of a -lactose hydrate.  The initial heat treatment may be that required for pasteurization (161 DEG F. for 15 seconds) or for sterilization (285 DEG F. for 15 seconds).
