Title: Improvements in gas-heated kettles and the like
IPC: A47J27/21
Filed: 1933-04-13
Abstract: 417,675. Valves. FOURNESS MANUFACTURING CO., Ltd., and MARTIN, J., Pritchard Street, Chorlton-on-Medlock, Manchester. April 13, 1933, No. 11020. [Class 135.] In a gas operated water heater, floatcontrolled means are provided for shutting down the gas supply valve when the water boils. The heater comprises outer and inner shells a, a<1> forming an annular water space therebetween and a double-conical film heating element d. The draw-off tap c carries an overflow e which communicates by a pipe k with a narrow float chamber i, a second pipe connecting the lower end of the chamber with the main water space. The pipe is of smaller bore than the pipe k, or has its entrance restricted, so that water boiling air into the chamber i will raise the level in the chamber. A float l in the chamber i is attached to a central tube m which slides over a fixed tube n and carries a rod o passing through the tube n and attached to a crank on a disc p. A second rod r on the disc p carries a plunger r<1> lying immediately over the spindle of the gas supply valve s, the action being such that if steam is generated in the heater d it passes into the chamber i and raises the float l, whereupon the plunger r<1> is depressed to close or partly close the gas valve s. When the water ceases to boil, or when a supply is drawn off, the water level in the chamber i is lowered and the plunger r<1> is raised to allow the attendant to open the gas valve again. Alternatively, the gas valve may be positively opened by the plunger r<1> or may be self-opening. The plunger may be guided by light springs r<2> attached to a tube q which encloses the rod r and may have its upward movement limited by a shoulder thereon engaging the tube. The disc p may be located in an extension i<1> of the chamber i or may be located in the chamber and the rod r provided with a gland or a bellows fitting. The apparatus may be effective to prevent damage to the heater if the water level therein should fall to a dangerous level, due to the water boiling readily. The main water level x is controlled by a float g operating a valve h on the supply pipe f, and a pivoted pilot jet b<1> for the gas supply is provided. The apparatus may be used in connection with cookers or radiators which require to have the gas supply shut off when the water boils.

Title: Apparatus for measuring turbidity
IPC: G01N21/53
Filed: 1973-03-07
Abstract: 1420002 Photo-electric turbidimeters ROBERT BOSCH GmbH 7 March 1973 [8 March 1972] 11172/73 Headiog G1A In apparatus for photo-electrically measuring turbidity of a gas, the gas is passed through a chamber 10, having input and output light apertures 15, 16, which are closed by respective rotating discs 15, 16 which entrain boundary layers of substantially pure air so that the surfaces of the discs are kept free of contamination by the gas under test, and the gas does not penetrate to contaminate the source and detector surfaces. Diesel exhaust gases are passed through measurement chamber 10 via inlet 13 and outlet 14, a reference gas being contained in vessel 11. Light from a wide band (sunlight characteristic) source is passed e.g. via mono-chromatic ultraviolet transmitting filters to mirrors 26, 27, to define test and reference beam paths comprising lens systems 29, lenses 33, test and reference chambers, scattered light removing diaphragms 34 and light guides 35, 36 leading to detector 37, which may be provided with suit able colour filters. The discs 15, 16 are each formed with alternate transparent and opaque sectors 31, 32 such that the test and reference beam paths are effective alternately, to provide a detector output which alternates between two levels dependent on the light absorption within the test and reference vessels respectively. Either the difference between these levels is sensed and indicated or it is used to control rotation of a polarizer 30 in the reference path to equalize the levels, the angular position of the polarizer being calibrated directly in gas turbidity. Alternatively, an angle transducer senses the polarizer position and feeds an electrical indicator. An interference filter 28 is arranged in the test path to balance the beam intensities. When a rapidly changing process is to be monitored, the polarizer cannot be used and an oscillograph may be employed. By use of mono-chromatic light, concentration of particular substances may be measured. The gas being measured may be heated or cooled before test, by a suitable heat exchanger jacket.

Patent GB-893466-A (GB)
Title: Process for dyeing or printing nitrogenous fibres
Filed: 1960-03-30
Abstract: Nitrogenous fibres, such as wool, silk or polyamide fibres, are dyed or printed with a 1 : 2-chromium or 1 : 2-cobalt complex compound of an azo dyestuff containing at least two acid solubilising groups in the complex, the operation being effected in the presence of a cationic, surface-active compound containing no polyglycol ether chains.  The complex may comprise two similar or dissimilar azo dyestuffs per atom of metal and the acid groups, e.g., sulphonic or carboxylic acid groups, may be attached to one or both dyestuff molecules, and numerous complexes are specified. Specified cationic compounds are quaternary ammonium compounds such as cetyl trimethyl ammonium bromide, cetyl pyridinium bromide, tetradecyl pyridinium bromide, dimethylbenzyl lauryl ammonium chloride, dimethylbenzylstearyl ammonium chloride, dihydroxyethyl benzyl lauryl ammonium chloride, dimethylcyclohexyl lauryl ammonium bromide, quaternary ammonium salts containing at least two quaternary ammonium nitrogen atoms, and salts, if desired quaternary ammonium salts, of basic condensation products of alkylolamides of higher fatty acids with alkanolamines, such as the acetate of the condensation product of stearic acid methylolamide with triethanolamine.  The dyebath also preferably contains a non-ionic dispersant, e.g., a polyglycol ether of an alcohol or alkylphenol or of a fatty acid or alkylmercaptan. Dyeing is preferably effected in an acid bath at temperatures up to the boil.  The wetfastness of the dyeing is increased if the pH of the bath is increased to above 6 after the fibres have absorbed the desired amount of dyestuff, and when mixtures of nitrogenous and cellulose fibres are to be dyed, a direct dyestuff for the cellulose fibres may be added to the bath after the pH has been so raised.  The process is also particularly suitable for the melange printing of worsted slubbings, the paste containing, in addition to the dyestuff and cationic agent, the usual thickness and, if desired, an acid such as acetic acid, urea, oil of turpentine and sodium nitrobenzene sulphonate. Numerous examples are given.
