Title: Improvements in the production of a linen-like finish on cotton fabrics
IPC: D06M15/05
Filed: 1940-06-25
Abstract: 541,030. Treating textiles with liquids etc.; coated fabrics. BLEACHERS ASSOCIATION, Ltd., KERSHAW, W., and WHITELEGG, C. J. June 25, 1940, No. 10837. [Class 15 (ii)] [Also in Group VIII] A linen-like finish is imparted to a cotton fabric by subjecting it, after bleaching, to a calendering or beetling treatment and then coating it with a solution in alkali of regenerated cellulose, a modified cellulose, or a cellulose ether, then partially drying it, treating it for the removal of alkali and washing and drying it. The fabric may be mercerized before or after bleaching. The calendering or beetling renders the fabric less permeable to the cellulose solution so that practically only the surface threads and hairs are coated and a lustrous, transparent film resistant to laundering is formed thereon. A lower alkyl cellulose ether or a glycol cellulose ether may be used. The solution is preferably of high viscosity, e.g. at least 50 c.g.s. units. Before the bleaching, the fabric may be dry cleaned with benzine, benzene, a chlorinated hydrocarbon, or other solvent for oils, fats, waxes, or resins. The process may be applied to the treatment of cotton drill, damask, or brocade fabrics. The cellulosic solution may be applied to both sides of the fabric. Specification 462,824 is referred to.

Title: Improvements in or relating to mill trains for the production of sheet metal discs by rolling out a thicker disc-shaped workpiece of smaller diameter
IPC: B21H1/02
Filed: 1937-04-16
Abstract: 473,246. Rolling discs. SCHUSTER, H. April 16, 1937, No. 10872. Convention date, May 27, 1936. [Class 83 (iv)] In mill trains foi producing sheetmetal discs by making thicker discs alternately elliptical and circular between double rolls, the roll stands are relatively angularly arranged to avoid turning and centring the circular or elliptical work pieces. In the form shown in Fig. 2, two double rolls f, g are employed with their axes at rightangles. The rolls f convert the circular discs into an elliptical one z which is pushed to the rolls g for conversion to a circular disc of reduced thickness. Mill trains with the axes of the double rolls relatively inclined are described. The axes are at 90‹ in the train shown in Fig. 3. In a modification, a ground plan shows the rolls with a meandering line with rectangular turns. A polygonal plan providing a total turn of 120‹ is described. The circular work piece may be rolled to an elliptical shape and vice versa in several parallel passes in succession. Rectangular and meandering plan constructions with rolls having successive parallel passes, are described.

Title: Improvements in and relating to non-woven fabrics
Inventor: VALENTINE LESLIE MACKENZIE
IPC: D04H1/06
Filed: 1960-04-01
Abstract: Non-woven fabrics made from a mixture of fibres of which not less than 10% by weight are nylon fibres, and which are bonded together by a resin or elastomer, are treated with a mineral acid to cause the nylon fibres to shrink preferentially, the acid is then removed, and the fabric is washed and dried, the treatment being such that the area of the fabric after shrinking is from 20% to 60% less than the area of the fabric before treatment.  The remaining 90% or less of the fibres, which do not shrink, or shrink less than the nylon fibres may be e.g. viscose rayon, polyester or wool.  The bonding agent may be e.g. polyvinyl chloride, rubber, polyacrylate, or a copolymer of acrylonitrile and butadiene.  Specified mineral acids are hydrochloric, sulphuric and nitric acids.  Shrinking occurs during the acid treatment and during drying.  Removal of acid may be effected by neutralisation with e.g. aqueous sodium carbonate.  The strength, abrasion resistance, extensibility, elasticity, appearance, softness, draping qualities, sewability and crease resistance of the fabrics are improved, and the tendency for fibres on the surface of the fabric to form fluff is reduced.  Specification 659,088 also is referred to.

IPC: C10G15/00
Filed: 1916-08-18
Abstract: 118,122. Maxim, S., and Crosse, A. W. Aug. 18, 1916. Hydrocarbons, cracking.-Heavy hydrocarbons such as kerosene are converted into lighter hydrocarbons by subjecting them while under pressure and at a high temperature to agitation and electrochemical action. The operation is effected in a cylinder A closed by detachable caps C and arranged to rotate on hollow trunnion shafts B, B<1>. The inner surface of the cylinder is coated with copper. The cylinder is partly filled with oil, and a small quantity of pieces of zinc together with a solution of salt, sulphuric acid, pruesiate of potash, or other substance capable of setting up electro-chemical action is added. Pieces of copper also may be added. The air in the cylinder is pumped out and may be replaced by hydrogen under pressure, The cylinder is then rotated over a heater J until the pressure is raised to 300-500 lb. per sq. in. After several hours, the liquid is cooled, a mixture of a volatile spirit and a very heavy oil being obtained. The cylinder is charged through an aperture closed by a cap K. The trunnion B communicates with a pressure gauge G, and the trunnion B<1> is connected to a flexible diaphragm H by which the gas supplied to the burner J is regulated in accordance with the pressure in the cylinder.
