Inventor: BAUMANN HANS
IPC: C09B3/00
Filed: 1961-02-10
Abstract: The invention comprises anthraquinone, pyrene-quinone, perylenetetracarlboxylic acid diimide and perinaphthalene-tetracarboxylic acid diimide dyes which contain at least one group of the formula <FORM:0924258/IV(a)/1> attached by way of an amino group, where X is a hydrazino or substituted hydrazino radical and Y is chlorine, bromine, hydroxyl, sulphhydryl, sulphonic acid, primary, secondary or tertiary amino, an ether or thioether group or a hydrazino or substituted hydrazino radical.  The dyes are made by reacting cyanuric chloride or bromide with hydrazine or a substituted hydrazine and an anthraquinone, pyrene-quinone, perylene- or perinaphthalenetetracarboxylic acid diimide dye containing a primary or secondary amino group and preferably containing a water-solubilizing group and then if desired hydrolysing the remaining triazine halogen atom or treating it with a metal sulphite or sulphide, ammonia, a primary or secondary amine, an alcoholate, a mercaptan, hydrazine or a substituted hydrazine. Anthraquinone dyes include those derived from pyranthrone, violanthrone, isoviolanthrone and benzanthrone.  Substituted hydrazines specified are methylhydrazine, N:N-dimethylhydrazine,1 acetylhydrazine, phenylhydrazine, phenylhydrazine-3-sulphonic acid, semicarbazide, thiosemicarbazide, aminoguanidine, hydrazo dicarboxylic acid amide, 2:3:6:7:9:10-hexa-aza-decahydronaphthalene, maleic hydrazide, phthalic hydrazide, N-aminoethylurethane, N-aminopiperazine, 2:4:6-trihydrazino-1:3:5-triazine, pyrazoline and hexahydropyridazine.  The dyes may be converted to their methylol compounds by reaction with formaldehyde for example at pH 7,5, and thence to the corresponding ethers or esters.  Examples are given. The dyes dye and print textile materials of wool, silk or polycaprolactam and dye leather or paper.  The methylol compounds or their esters or ethers dye or print textile materials of natural or regenerated cellulose in the presence of hardenable aminoplast-forming substances or their precursors and acids or acid-reacting substances and if desired aldehydes such as formaldehyde.  The dyes are then fixed by a heat treatment.  In examples (1) cotton fabric is padded with an aqueous solution of a dye of the above formula containing dimethylolethylene urea and ammonium nitrate, heated and washed to give a crease-resistant fabric, or the dimethylol ethylene urea may be omitted; cotton fabric treated with caustic potash solution is padded with an aqueous liquor containing a dye of the above formula, dimethylolbutane diol diurethane, dimethyl dimethylolurea, polyacrylamide, polyethylene diamine, an aqueous suspension of the condensation product of stearic acid and dihydroxyethyl diethylene triamine and ammonium nitrate, dried, schreinerized and heated; (3) cotton fabric is padded with an aqueous solution of a dye of the above formula, 1:3-dimethylol-5-methylperhydrotriazone-(2) and monoammonium phosphate and dried and heated.

Abstract: 452,046. Endless - belt conveyers. MINING ENGINEERING CO., Ltd., and NYBORG, T. G., Meco Works, Worcester. Feb. 16, 1935, Nos. 5097 and 28467. [Class 78 (i)] For removing spillage from the lower run 2 of a belt conveyer before it reaches the return drum 9 and returning it to the upper run 1, there is provided within a compartment adjacent the conveyer a chain conveyer of the scraper type comprising two parallel endless chains 5 connected by transverse scrapers 6. The chains are driven from the shaft 8 of the return drum through a one-way clutch whereby the scraper chains remain stationary if the direction of movement of the conveying belt is changed. Spillage is directed into the compartment in which the scraper chains work by stationary ploughs 3. Any material that passes over the return drum is removed by a scraper 19 and deflected by inclined guides 20 eventually to the belt in front of the rear plough. In the form shown in Fig. 5, an ordinary link chain is used. The unit may be permanently attached to the return drum or may be removable therefrom. In another modification, not shown, a chain conveyer itself acts as a plough travelling transversely across the bottom run of the belt conveyer.

Title: Improvements in and relating to the ageing of viscose
Inventor: WEIGHAM WILLIAM REGINALD
IPC: D01F2/08
Filed: 1952-02-27
Abstract: In the ageing of viscose as it passes from the point at which it is formed to the point at which it is delivered to a spinning or casting machine it is passed through one or more heat-exchangers having a small capacity compared with the total volume of the viscose between the two points so that any temperature deviations of the viscose from a predetermined ageing temperature are corrected and the viscose is aged in a substantially uniform manner.  The viscose is preferably passed through a heat-exchanger directly after passing through a stage where the viscose is particularly liable to undergo temperature changes, for example, a filtration stage.  Air conditioning of the "caves" containing the viscose storage tanks and auxiliary equipment may also be employed to control the temperature of the viscose.  The heat exchanger may be a block of high heat transference material, for example compressed carbon, through which two sets of holes extend e.g. at right angles, the viscose being passed through one set and the heat-exchanger fluid through the other.  In the example freshly prepared viscose passes successively through a filter, a heat exchanger, a storage tank (which may be situated in an air-conditioned atmosphere), a drop tank, a pump, a filter, a second heat exchanger, a deaerator, and a second pump to a spinning machine, the various units being connected by pipes in the usual manner.  The heat exchangers are supplied with a cooling or heating medium, such as brine, in order to adjust the temperature of the viscose to the desired ageing temperature.

Title: Improvements in or relating to the Manufacture of Chemical Compounds.
Inventor: ROBERT ESNAULT-PELTERIE
IPC: C01B21/20
Filed: 1916-04-10
Abstract: 100,275. Pelterie, R. Esnault-. April 9, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Nitrogen oxides. -In a process described particularly for the synthetic production of nitrogen dioxide but stated to be applicable to the formation of other compounds by reactions between gases, or gases and finelydivided liquids and solids, the reaction mixture is suddenly compressed so as to produce a very high temperature, and then immediately expanded so as to produce cooling and prevent dissociation of the compound produced. The apparatus described consists of a strong cylinder C<1> and a piston C attached in a special manner to a cross-head A driven from a crank. The cross-head is formed with a cavity D at the bottom of which is a spring of small compressibility such as a Belleville washer G, and an integral collar B on the end of the piston C is normally in contact with this washer under the action of a spiral spring H, which may be surmounted by two Belleville washers G<1>, G<2>. The reaction mixture is delivered under some pressure through a pipe L and is compressed by the piston, which is driven at very high speed so that, when the cross-head reaches its extreme forward position the piston will move forwards owing to its kinetic energy, in opposition to the spring H, and will further compress the gas, to a degree independent of irregularities in the joints connecting the cross-head with the driving-shaft. A pressure 200 times that at which the gas is supplied is mentioned. On reaching the point of highest compression and temperature, the mounting of the piston allows of immediate expansion of the compressed gas, and the piston moves back with a greater speed than the cross-head and its end B finally reaches the washer G when these parts have nearly the same speed. When the crosshead has reached its extreme backward position a valve I is opened and a fresh quantity of gas enters from the pipe L, expelling the treated gas by a pipe M. The amount of clearance between the piston and the valve I is regulated by a nut P and spring K<1>, and, if desired, the cylinder may be mounted between Belleville washers N as shown in Fig. 2 to minimize shock. In that case there must be provision for lost motion between the valve I and its beam T. The cylinder may be aircooled as shown in Fig. 1 or water-cooled as shown in Fig. 2. To increase the temperature of the compressed gas mixture without increasing the pressure to the same extent there may be mixed with the gas an explosive mixture, for instance air and combustible gas or liquid, or hydrogen and chlorine. Then the system may be worked as a motor without external power.
