Title: Manufacture of azo-dyestuffs
IPC: C09B29/08
Filed: 1938-07-11
Abstract: 517,023. Dyes ; intermediates ; dyeing cellulose esters and ethers. SOC. OF CHEMICAL INDUSTRY IN BASLE. July 11, 1938, Nos. 20491 and 20495. Convention dates, July 10, 1937, and June 20, 1938. [Classes 2(iii) and 15(ii)] Azo dyes free from sulphonic acid groups are made by a diazotised aromatic p-nitroamine with a coupling component of the formula where X, Z1 and Z2 are H or alkyl, and Y is a carbon chain of at least two C-atoms attached #Z1 to the group -#C-cooH through a hetero-atom. #Z2 The coupling components may be made by reacting a component of the formula with an amino-, hydroxyl- or mercapto-carboxylic acid, e.g., glycollic acid, thioglycollic acid, alpha-oxypropionic acid or glycine. They may also be made by reacting #-hydroxy-, amino- or mercapto-alkylaminobenzenes with alpha-halogenated aliphatic acids, e.g., chloracetic, alpha-chlorpropionic, alpha-bromopropionic, or alpha-bromobutyric acids. The compounds in which the heteroatom is sulphur can be oxidised to sulphoxides or sulphons, which may also be used as coupling components. The reaction products of aromatic amines with epichlorhydrin, of the formula may also be reacted with bodies such as aminoacetic acid and thioglycollic acid to produce suitable coupling conponents. The dyestuffs, in the form of their alkali metal or ammonium salts, are water-soluble and have pronounced affinity for cellulose esters and ethers. Small quantities of substances having an alkaline reaction, e.g., ammonia or an alkali salt of phosphoric acid, or an organic base such as pyridine or ethanolamine, may be used in dyeing such esters and ethers. In examples, p-nitraniline is diazotized and coupled with (1) 2 - (N - ethyl - N - phenylamino) - ethoxy - acetic acid and (2) 2 - (N - butyl - N - 3 - methylphenylamino) - ethoxyacetic acid ; the products dye cellulose acetate artificial silk in red shades. Specification 422,843 is referred to.' The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 517,918.

Patent GB-579676-A (GB)
Title: Improvements in or relating to the polymerisation and interpolymerisation of ethylene
IPC: C08F10/00
Filed: 1943-12-10
Abstract: In the manufacture of solid and semi-solid polymers and interpolymers of ethylene by polymerization at elevated temperatures and pressures, the ethylene used is free from, i.e. contains less than 0.2 per cent by volume of, aliphatic compounds containing carbon, hydrogen and oxygen, e.g. aldehydes, ketones, alcohols, ethers and acids.  These impurities may be removed by fractional distillation, by washing with water or by using adsorbent charcoal.  Alternatively, the presence of impurities may be minimised by control of the conditions under which the ethylene is manufactured.  In an example, ethanol is dehydrated over phosphoric acid on coke at 310 DEG  C., scrubbed with cold water, passed over adsorbent charcoal and dried with calcium chloride. The invention is applicable also to the interpolymerization of ethylene with other monoolefines, vinyl esters and unsaturated acids and their derivatives.  Specifications 471,590, 497,643 and 8070/40, as open to inspection under Sect. 91, are referred to.

Abstract: 1380511 Continuous furnace; preventing ingress of air INTERNATIONAL BUSINESS MACHINES CORP 2 May 1973 [19 June 1972] 20960/73 Heading F4B [Also in Division H1] A gaseous-reaction tube 10, e.g. for use in the oxidation, diffusion or etching of semi-conductor wafers 24 which move successively through entrance, reaction and exit zones of the tube, includes aligned, longitudinal partitions 12, 14 at its entrance and exit zones, and gas inlets 16, 18 for introducing a gas under the two partitions 12, 14. Reaction gas is introduced to the uniformly heated reaction zone through a central inlet 20 and the flow of gas into the inlets 16, 18 is controlled so that back pressure develops beneath the partitions 12, 14 and some of the introduced gas flows out into the edge of the central reaction zone, causing the reaction gas flow to be deflected above the partitions 12, 14 on its way to exhaustion from the ends of the tube 10. A well defined reaction zone is obtained in this manner. Down-turned extensions of the partitions 12, 14 may be provided as shown to restrict flow of gas from beneath the partitions 12, 14 into the reaction zone, and similar extensions at the opposite ends of the partitions may restrict escape of gas out of the tube 10. The gas introduced into inlets 16, 18 may be inert, forming a purge gas, but sequential processing may be obtained if different reaction gases are fed into the inlets 16, 18 and 20.

Patent GB-212285-A (GB)
IPC: H05G1/61
Abstract: 212,285. McDonald, L. R. Nov. 7, 1922. R÷ntgen-ray apparatus.-In stereoscopic Rontgen-ray apparatus employing two alternately energized tubes, one phase of an alternating current is employed to energize one tube and to cause movement in one direction of an oscillating vibratory viewing-shutter, and the opposite phase to energize the other tube and to cause movement of the shutter in the opposite direction. In one form, Figs. 4, 5, the shutter consists, of a resilient vibratory strip 62, supported from a block 46 secured to a base 1, having two shutter-blades 66, 67 attached to its free end in front of two peep-holes 68, 69 in the base 1. The length of the free portion of the strip 62 can be varied by vertically adjusting a block 60 through which the strip passes by means of a screw 52. The strip is actuated by two electromagnets, one on each side, built of alternate plates of soft and tempered steel, the tempered plates of the two magnets being oppositely polarized so that when an alternating current is sent through the magnet coils 17, one will be activated by one phase of the current and the other by the opposite phase, the strip 62 being attracted to each in turn, causing alternate covering and uncovering of the peep-holes 68, 69. The current for the R÷ntgen tubes 33, 35, Fig. 21, and for the electromagnets 17 comes from the same mains 20, 27 so that when one tube 35 is activated it throws an image of the object 40 on the screen 41 viewed by the eye 43 at the diagonally opposite peep-hole, which is at that instant uncovered by the oscillation of the strip 62. Similarly, the image produced by the tube 33 activated by the succeeding phase, of the current, is viewed by the other eye 42. In a modification, two vibrating strips each carrying a pair of shutter-blades and each adapted by permanent magnetization or otherwise to be separately attracted in opposite directions by the electromagnets are employed so as rapidly to cover and uncover the peep-holes in turn according to the alterations of the current. The device is provided with a cover attached to the base I and its lower end has a felt shield which bridges the nose of the wearer. A padded head-rest 9 is pivoted to the base and is provided with straps to allow the device to be attached to the head and to be swung up out of line with the eyes.

[Class 125 (iii)] In closures for cans, jars, and like containers an opening for the insertion of a ring is provided at such a height in a depending wall of the lid that such ring engages between a projecting rim on the container and a projection on the lid to hold the latter on to the container. The body d of a can is formed around its upper margin with a bead e, and the lid a has a downwardly projecting flange g bent in at the bottom to form an inner shoulder h located below the rim e and of such a diameter that the shoulder h may pass over the rim e. An inwardly pressed circumferential portion i centres the lid on the can, and a packing ring k fits between the lid a and the top of the can. To secure the lid in position, it is pressed down on the can to compress the ring k and a wire c is pushed through a hole b in the flange of the lid to fit between the rim e and the shoulder h. An eye n on the ring c protrudes from the hole b so that the ring may be withdrawn when the lid is to be removed. The hole b is formed with an extension b<1> so that a knife may be slipped between the lid a and the packing ring k to break a vacuum seal if desired. The lids may be used in connection with cans, the tops of which have been cut away.
