Title: Optically brightened polyacrylonitrile and cellulose acetate materials
Inventor: BALLI HEINZ
IPC: D01F1/10
Filed: 1960-03-31
Abstract: Textile materials, i.e. fibres, flocks, yarns, threads, woven and non-woven fabrics and films, comprising polymers of acrylonitrile or cellulose acetate are optically brightened by incorporating into the polymers or into the cellulose acetate, before or during the spinning of the textile materials, an azamonomethine cyanine compound of the formula <FORM:0895084/IV (a)/1> in which Y and Y1 are identical or different and each represents a hydrogenation, a methyl group of a methoxy group and X is an anion, e.g. an inorganic anion such as a chloride, bromide, iodide, perchlorate or sulphate anion or an organic anion such as an alkylsulphate or arylsulphonate anion.  From 0,01 to 5% of brightening agent, with reference to the weight of the material to be brightened, may be used.  Cellulose acetate, the acetyl content of which lies between 2 1/2 and 3 groups per anhydro-glycose unit, and polymers of acrylonitrile and copolymers thereof with vinyl chloride, vinyl acetate or methyl methacrylate containing more than 50% by weight of acrylonitrile, may be treated. Specifications 447,038, 461,668 and 461,688 are referred to.ALSO:Fibres, flocks, yarns, threads, woven and nonwoven fabrics and films comprising polymers of acrylonitrile or cellulose acetate are optically brightened by treating them with an azamonomethine cyanine compound of the formula <FORM:0895084/IV (c)/1> in which Y and Y1 are identical or different and each represents a hydrogen atom, a methyl group or a methoxy group and X is an anion, e.g. an inorganic anion such as a chloride, bromide, iodide, perchlorate or sulphate anion or an organic anion such as an alkylsulphate or arylsulphonate anion.

Abstract: 568,635. Weighing ingredients for potter's clay or other mixtures. WEDGWOOD & SONS, Ltd., J., and WEDGWOOD, C. T. Aug. 5, 1943, No. 12644. [Class 143] In a method for obtaining a predetermined weight of solid material, for example, when blending ingredients for potter's clay, a liquid containing the solid in suspension is fed into a container, and the volume and weight are simultaneously measured by means that cause the feed to be automatically cut off and/or a visual or audible warning to be automatically given when a predetermined weight of solid is present. The method may be used to control the weight of a liquid suspended in, or mixed with another liquid whether in the form of an emulsion or otherwise. In an apparatus. for carrying out the method, a finger i mounted on slides a, b is given two movements at right angles to each other by means of electric motors a<3>, b<3>, the revolutions of which are controlled respectively by the rise of a float in the liquidreceiving tank and the increasing weight of the tank. The finger i ultimately makes contact with an inclined plate y which forms the negative end of an electric circuit and causes the flow of liquid to be automatically arrested and/or a visual or audible warning to be automatically given. The contact plate y is mounted on a parallel motion linkage and pivots about a pin v so that the position of the plate may be adjusted by means of hand wheels c, d according to the specific gravity and required weight of the suspended solid as indicated on graduated scales t, s.
