Title: Manufacture of pyrazolone-azo-dyestuffs
Filed: 1926-11-19
Abstract: 261,770. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). Nov. 19, 1925, [Convention date]. Azo dyes; lakes.-Azo dyes suitable for dyeing fibres of all kinds and for use in making lakes are made by coupling a diazo compound with a 1- (4<1>-chlor-5<1>-methyl-2<1>-sulpho) - phenyl - 5 - pyrazolone, in which the 3-position is substituted by a methyl, carboxylic, or carboxylic ester group. In examples, (1) the sodium salt of the ethyl ester is coupled with o-anilinesulphonic acid to yield a product which dyes wool fast yellowish-green tints; similar products are obtained from other esters, e.g. the methyl and butyl esters, (2) the sodium salt of the ethyl ester is coupled with aniline; the product dyes wool a level yellow tint, (3) the sodium salt of the methylpyrazolone is coupled with 4-chloraniline-2-sulphonic acid; the product dyes wool a fast greenish yellow, (4) the sodium salt of the carboxylic acid is coupled witn 2-aminotoluene-3 : 5-disulphonic acid; the product dyes wool a greenish-yellow tint, fast to light, and gives greenish lakes with barium sulphate, and (5) the sodium salt of the methylpyrazolone is coupled with tetrazotized 4 : 4<1>-diaminodiphenyldimethylmethane, yielding a yellow dyestuff fast to milling and washing and particularly suitable for dyeing yarn. If chromable groups are present in the diazo compound, the fastness of the dyeings may be increased by afterchroming in the usual manner. Specification 243,758 is referred to. Pyrazolones.-The above-mentioned pyrazoiones are obtained by condensing the corresponding hydrazine with an ester of acetoacetic or oxaloacetic acid ;n the known manner, a mild, non- saponifying agent, e.g. sodium carbonate, being used when the carboxylic esters are desired.

Title: Kiln for automatic steam-cooking and treatment with aeriform fluids
IPC: C08B30/16
Filed: 1929-09-28
Abstract: 338,286. Morin, R. L. M. Oct. 3, 1928, [Convention date]. Piston type.-Apparatus, more particularly for cooking tapioca by steam, but applicable to treating any material with any gas, comprises a treatment chamber 1 to which the gas is admitted through a heater 11 and from which it is exhausted through a valve controlled duct 14, a conveyer 2 which carries the material through the chamber 1 and has sealing means 7, 8 co-operating with long narrow passages 5, 6 at the entrance to and exit from the chamber. In the case of steam cooking, the top of the chamber is curved so that condensed steam runs towards the sides and does not fall on the material. A shield 13 prevents steam from impinging directly on the conveyer. The conveyer consists of a number of parallel narrow spaced bands, e.g. of steel, connected by cross members 15, Fig. 4. Yielding pads 7, 8 H are attached above and below the members 15, or are arranged between the members 15. The securing bolts or rivets are accommodated inside the body of the pads 7, 8 so as not to prevent the pads from contacting with the passages 5, 6. The conveyer may be adapted to receive granular material by securing overlapping plates 16 to the face of the conveyer by rivetting the forward edges of the plates to the bands at 17. In modifications, the height of the pads 7 is adjustable by metal packing strips, or the pads 7 each consist of a resilient strip secured to the cross member 15, a T-bar secured to the strip and a flexible sealing-blade secured to the vertical web of the T-bar. The conveyer may consist of a single endless band of rubber, fibre or the like, and the sealing pads may be of anti-friction metal with springs or rubber parts interposed between the pads and the belt. Belt tensioning and speed regulating mechanism is provided. Specification 316,291, [Class 58, Grain &c.], is referred to.

Title: Improvements in and relating to work-holding and positioning means for use in metal-cutting machine tools
IPC: B21G1/12
Filed: 1932-10-21
Abstract: 407,761. Making needles &c. FAIRWEATHER, W. C., 65, Chancery Lane, London.-(Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) Oct. 21, 1932, No. 29466. [Classes 83 (ii) and 83 (iii).] Milling; blanks, transferring.-In a device for positioning round longitudinally grooved articles, such as sewing-machine needle blanks, so as to be presented correctly for a machining operation, the article is frictionally rotated and is arrested in a definite position by a yielding detector which engages the longitudinal groove. As applied to the machining of needles, such as milling near the eye or slabbing of the shank, the needles are fed one at a time along a groove 1<1> in the bed 1, point first, towards the holding jaws 4, 7. Both jaws are pivoted to the bed at 11, the jaw 4 having an extension 4<1> connected by a linkage 20, 18, 17, 7<1> to the jaw 7 so that the two jaws oscillate about the pivot 11 in opposite directions. A spring 10 acting on the extension 4<1> normally maintains the jaws closed. The jaw 7 is grooved at 21, Fig. 6, to receive the cylindrical shank of the needle and the jaw 4 has a semi-cylindrical recess 5 to receive the blade of the needle and a depression 22 for the end of the shank, the recesses 5, 22 being formed in an interchangeable block 2 attached to the jaw 4. The jaw 7 is also replaceable to suit different sized needles. A spring blade 8 attached to the jaw 7 projects up through a slot 9 in the jaw and into the recess 5 so that as a needle is fed axially between the jaws, its shank is rotated by a friction roller 6 until the end of the blade engages the longitudinal groove therein, thus positioning the needle for the machining operation. On completion of the machining operation, the jaws are released by a cam-actuated lever 14 having an adjustable screw 15 engaging a projection 13 on the jaw 7. Whilst the needle is being machined, its free end is held by a chuck, (not shown). The closed position of the jaws 4, 7 is determined by an adjustable stop contacting with a projection on the jaw 7. Specification 26096/11, [Class 83 (iv)], is referred to.

Class 64(1) A method of heating liquids comprises passing a heated gas or vapour, for example substantially dry saturated steam, continuously into a continuous stream of the liquid, the heated gas or vapour being passed into the liquid by means of a duct which passes down through a vortex which has previously been created in the liquid in such a manner that over the whole or greater part of its length below the upper surface of the liquid, the duct is out of contact with the greater part of the liquid. A heater in which the process may be carried out is shown in vertical crosssection in the Figure. The liquid enters the heater through pipe 29 which extends into the heater and just through draught tube 33; the liquid leaves through pipe 19. The draught tube is mounted coaxially, supported at the bottom by notches 34 formed in a radially mounted series of baffles 36, and at the top by a series of struts 37. The heating agent is supplied through a duct 38, the lower end of which is in the same horizontal plane as that of the draught tube and which passes downwards through the draught tube. A rotary impeller 39, with blades 41, is mounted just below the duct and guard tube so that when the impeller is in action a vortex (indicated by dotted lines 49) forms in the liquid, and the gas or vapour is uniformly dispersed throughout the liquid. The impeller also acts so as to cause a vigorous vertical circulation of the liquid.
