IPC: A41F9/00
Abstract: 106,620. Batchelder, F. R. May 23, 1916, [Convention date]. Void [Published under Sect. 91 of the Act], Pouches.-Woven pocketed carriers, such as are employed as cartridge-carriers, hospital-corps belts, medical-officers' belts, &c., are formed with a woven cover which encloses the top, sides, and front. As shown in Figs. 1 and 2, the woven belt A has one or more woven pockets B, which are shown expanded by packages C. Each cover is formed of two woven strips, one D, D', D<2> passing from back to front and bent twice at rightangles, the other E, E<1> passing from side to side and also bent twice at right-angles. One extremity D of the first-mentioned strip is inserted in a housing-slit in the belt and is secured by stitching, and the two strips, which cross at the top, making that part of double thickness, are stitched together along the four edges of the top. The two strips are also stitched together along the side edges, the cover thus forming a hood for the pocket. The free ends of the front D<2> and the sides E are folded and hemmed. The cover is secured in place by a press-fastening H, J. Instead of the strip that passes from side to side being stitched to the top, it may be stitched to the front flap, thereby producing a hood having a single thickness at the top, but a double thickness at the front. Or again, both top and front may be of single thickness. This may be done by stitching side flaps to the strip that passes from back to front, or by weaving a piece of the shape shown in Fig. 6, so. that when the edges d', e' are secured together it will form the desired hood cover. The invention is not limited to the forms of cover described, so long as the woven cover is of such a shape as to enclose completely the top, sides, and front of the pocket like a hood.

Title: Improvements in and relating to methods of making cellulose ether carboxylic acids
IPC: C08B11/12
Filed: 1944-06-09
Abstract: Cellulose ethers of hydracrylic acid or a -methyl hydracrylic acid are obtained by reacting cellulosic material with a solution of an alkali-metal hydroxide and then subjecting the mixture to reaction with acrylonitrile or a -methacrylonitrile.  Any alkali metal hydroxide such as sodium, potassium or lithium hydroxide may be used in solutions of more than 10 per cent and preferably 20-40 per cent concentration.  Cellulosic material such as cotton or wood pulp, or cellulose derivatives containing free hydroxyl groups such as methyl, ethyl or other alkyl, oxyalkyl, aryl substituted alkyl or carboxy alkyl derivatives of cellulose may be employed.  Heavy metal derivatives of the ether-acids may be obtained by reacting the alkali metal salt with a heavy metal salt, e.g. the salts of tin, zinc or lead.  In an example alpha-cellulose flock is dissolved in sodium hydroxide solution and acrylonitrile is added slowly.  The mixture is stirred for 15 hours at 25 DEG  C., acidified with dilute hydrochloric acid and poured into ethyl alcohol when the product separates.  The cellulose ether acids may be used as sizes or finishing agents for textile yarns or fabrics, in coating compositions, as adhesives, as intermediates for insecticides, pharmaceuticals, resins and plasticizers, and as wetting and emulsifying agents.
