Title: Manufacture of a New Physiologically Active Substance and New Compounds containing Nitrogen from Ovaries, Corpus Luteum or Placenta.
Inventor: IMRAY OLIVER
Filed: 1917-02-13
Abstract: 113,311. Imray, O., (Soc, of Chemical Industry in ra.clc). Feb.] 13, 1917. Medicines for internal use; hypodermic injec. tions. - A physiologically active substance containing carbon, hydrogen, and oxygen only (C = 81.3 to 81.6 per cent, H = 11.3 to 11.5 per cent) is isolated from placenta, corpus luteum, or ovaries, by extracting the tissues with a volatile solvent, evaporating the solvent, treating the residue with a body such as acetone in which the associated nitrogenous compounds are insoluble, and separating the precipitate; the resulting liquid contains the required product together with fats, cholesterol, and cholesterol esters; the latter are removed and the product purified by distillation in a high vacuum. The nitrogenous substances precipitated by acetone may be purified by solution in alcohol and reprecipitation with acetone; they are phosphatides containing nitrogen and phosphorus in approximately the ratio 5:2. The first-mentioned substance stimulates the female sexual organs; it is insoluble in water but may be emulsified by the colloidal aqueous solutions of the phosphatides, and used in this form for hypodermic injections. Specification 10877/15 is referred to.

Title: A method and apparatus for mechanically moving skeins of yarn during treatment with liquids
IPC: D06B3/08
Filed: 1929-07-24
Abstract: 316,227. Schlumpf, J. July 25, 1928, [Convention date]. Hank type apparatus.-In the dyeing and wet treatment of silk and cotton skeins supported on a roller 2 carried by a crank arm 3, no traversing movement in the direction of the threads is given to the skeins in moving the crank from its lowest to its highest position (Fig. 2), whereby both strands are lifted equally, but during descent of the crank (Figs. 4, 5) such a traversing. movement is given that the rear strand b<3> makes a forward movement while the forward strand b<2> remains stationary relative to the surface of the bath. The rotation of the roller 2 during descent of the crank is of the same angular velocity as that of the crank and the radii of the crank arm and crank roller are proportional (1: 2), so that. the desired result, is achieved. Figs. 6 and 8 show the apparatus, the cranks 3 being driven from shafts 6 by gearing 7. The roller 2 is caused alternately to rotate and to remain stationary on the crankpin 13 by means of a, clutch 28 moved by a camgroove 17 engaged by a pin 24 on the non-rotatable vertically-guided housing 18, causing the roller 2 to be clutched either to the crank-pin or to the housing 18. The stud which drives the collar containing the cam groove 17, Fig. 8, preferably engages with one end of a semi-circumferential groove so that the direction of rotation of the crank may be changed without disturbing the sequence of pure-lift and traversing movements of the skein. The carriers may be raised bodily by hydraulic pressure in cylinders 11.

Abstract: Disazo dyes are obtained by coupling tetrazotised 3 : 31 - dihydroxy - 4 : 41 - diaminodiphenyl with 2 mols. of the same or different coupling components of which at least one contains a nitrogen atom bound to not more than one hydrogen atom (e.g. that of an N-substituted aminonaphtholsulphonic acid, a pyrazolone or an acid amide), subject to the conditions that when the coupling is to a carbon atom of a naphthalene nucleus, the latter carries at least one sulphonic acid group and the coupling medium is made alkaline with an alkali or alkaline earth metal or ammonium hydroxide.  The products dye wool, silk, leather, cotton or regenerated cellulose fibres and may be converted into complex metal compounds by treatment in substance, in the dyebath or on the fibre with agents yielding metal, e.g. copper, chromium, iron, nickel or cobalt.  The metal compounds produced in substance may be incorporated in nitrocellulose lacquers, artificial resins and spinning masses.  Examples (1) to (5) relate to the production of the dyestuffs having as coupling components (1) 1-phenyl-3-methyl-5-pyrazolone or its 31-nitro- or 31-sulphonamido derivative (2 mols.), (2), (3) and (4), 5 : 51 - dihydroxy - 2 : 21 - dinaphthylamine - 7 : 71-disulphonic acid (2 mols.) in caustic potash, ammonia and caustic soda solutions respectively, (5) N-phenyl-2 : 5 : 7-aminonaphtholsulphonic acid (2 mols.).  In an example of the dyeing process, cotton is introduced into an aqueous solution at 40 DEG  C. containing the dyestuff of (2), sodium carbonate and sodium sulphate, the temperature is raised to 80-90 DEG C. and so maintained for 3/4 hour, whereupon copper tartrate and sodium carbonate are added, the temperature is maintained for 1/2 hour at 80-90 DEG  C. and the cotton is rinsed and, if necessary, soaped to obtain a fast blue dyeing.  The process of Specification 609,302 is disclaimed.  Specifications 455,274 and 609,301 also are referred to.  A sample has been furnished under Sect. 2 (5) of the dyestuff 3 : 31-hydroxy-4 : 41-diaminodiphenyl\sQ 2-(41-hydroxy-31-carboxyphenyl) -amino-5-naphthol-7-sulphonic acid (2 mols.), coupling being effected in the presence of calcium hydroxide. The Specification as open to inspection under Sect. 91 comprises also coupling to a naphthalene nucleus otherwise than in the presence of an alkali or alkaline-earth metal or ammonium hydroxide, and includes an example in which coupling with 2-(41-hydroxy-31-carboxyphenyl) -amino-5-naphthol-7-sulphonic acid is effected in the presence of sodium carbonate.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the heat treatment of bricks, pottery or the like
IPC: F27B9/26
Filed: 1919-01-31
Abstract: 139,267. Ionides, A. C. Jan. 31, 1919. Tunnel kilns for bricks, pottery, &c. The accommodation in preheating, firing, and cooling stages is proportioned to the times required for the respective operations, so that, while efficient transfer of heat from one stage to another is maintained, no stage is kept waiting, more or less empty, for goods coming from another. The firing-section a constitutes a continuation of the preheating-section a<2>, and communicates also with one or more cooling-sections a<1>, a<3> extending adjacent to the preheating-section and under the same roof, so that heat is directly transferred to the incoming goods by radiation and convection through extended openings f, Fig. 3. With this arrangement, in order to suit, say, a higher firing temperature, the cooling accommodation is readily increased by the use of additional parallel tracks for outgoing goods, and further alteration in relative accommodation in the three stages may be obtained by duplicating the preheating and cooling tunnel at the other end of the firing- chamber. Drying accommodation may be provided by a second parallel tunnel g supplied with hot air from a gas-fired device h, such air, if desired, first absorbing waste heat from, say, the hollow jacket of the tunnel a &c. The firing- burners d, Fig. 2, may be of the type described in Specification 136,296 for consuming a mixture of gas and air at constantly-related pressures above the atmosphere and mixed prior to ignition in the correct proportions for complete combustion. The burners on opposite sides may be in staggered relation and co-operate with extended combustion passages c<1>, as described in Specifications 108,701 and 114,223, passing transversely across the truck.
