IPC: G01N27/07
Filed: 1929-06-01
Abstract: 338,928. Slawinski, A. June 1, 1929. Turbidometers.-The concentration of suspensions which furnish sediments is determined by utilizing the variations in conductivity according to the position of the sediment in relation to the directive of the current. Two small glass tubes t, Fig. 1, of identical dimensions are closed at each end by metal plates n held in place by screwed covers p. These tubes are filled with the suspension to be tested and are connected in two arms of a wheatstone bridge, one tube being arranged vertically and one horizontally. Two pairs of tubes 1, 3, and 2, 4, Fig. 3, may be employed so as to permit simultaneous comparison of two different suspensions or of the same suspension under different conditions. The tubes are held between plates a in a wooden frame r which is removably mounted on a base m between stops k. The concentration is deduced from the ratio of the conductivity of the vertical and horizontal tubes and the height of the sediment in the vertical tube, which is graduated. The apparatus is applicable for determining the cell volume of blood and the fat content of milk and other emulsions.

Title: Improvements relating to the treatment of fibrous materials with liquids
Filed: 1935-06-18
Abstract: Esters, free from sulphur and derived from aliphatic monooxycarboxylic acids containing 2 to 6 carbon atoms and monohydric alcohols containing 4 to 8 carbon atoms and free from alkoxy groups, are used to improve the efficacy of liquids employed in the treatment of fibrous materials, such as textiles, wood, paper, leather, and hides.  Processes such as sizing, desizing, kier boiling, bleaching, mercerizing, carbonizing, scouring, spinning, finishing, dyeing and printing are stated to be improved.  Fibrous materials are readily wetted and impregnated, e.g., a stamping ink consisting of glycerine, Nigrosine and 0,5 per cent of glycollic acid hexyl ester is rapidly imbibed and produces a deep colour.  a -Ethylhexyl ester of glycollic acid and amyl lactate act similarly.  Esters of citric, malic, lactic and glycolloyglycollic acids are mentioned. When esters of monooxypolycarboxylic acids are used, the unesterified carboxylic groups, if present may be neutralized. Soaps, sulphonates, solvents and colloids may be used in conjunction with the wetting &c. agents. Dyed materials of improved fastness to boiling are produced when the agents are added to dye baths.  The Specification as open to inspection under Sect. 91 comprises also improving the wetting capacity of any liquid or the capacity of a solid for being wetted by a liquid by incorporating in the wetting liquid or in the solid to be wetted an ester derived from an oxycarboxylic acid, and an alcohol containing more than three carbon atoms.  Oxybutyric, salicylic and tartaric acids are mentioned whose esters may be used.  Reference is made to the use of the esters in the manufacture of therapeutic or cosmetic preparations, agents for combatting pests, fire extinguishing preparations, mordants, coating preparations, dust binding and cleansing preparations and cold asphalts.  They are also of use in the working up of ores.  This subject-matter does not appear in the Specification as accepted.
