Filed: 1957-06-05
Abstract: The invention comprises dyes of formula:  <FORM:0844869/IV (c)/1> where A is a radical of the benzene series containing two solubilising groups of the class consisting of carboxylic and sulphonic acid groups optionally carrying further substituents other than hydroxyl, amino or monoalkylamino groups, B is a 1, 4-phenylene, 1, 4-naphthylene or a 6-sulpho-1, 4-naphthylene radical which may contain Me and/or OMe but no other group, R is H, Me or Et and X is Hlg.  They are are made by reacting a cyanuric halide with a compound of formula A-N=N-B-NH. R.  The process is preferably effected in an aqueous medium at low temperatures in the presence of an acid-binding agent the product being isolated from the reaction medium at pH about 6,5. Cyanuric chloride and bromide are specified.  Examples of specified compounds corresponding to A are aniline 3, 5-di, 4-aminotoluene -2, 6-di- and 6-chloro -2- aminotoluene -3, 5- disulphonic acids, 4- sulpho -2- aminobenzoic acid and 2-aminoterephthalic acid.  Examples of compounds corresponding to B are #s-toluidine, 3-amino -4- methoxytoluene, N-ethyl-m-toluidene and 2-naphthylamine -7- sulphonic acid.  The dyes, in the form of their alkali metal salts, colour silk, wool, regenerated protein and cellulosic materials from an aqueous solution (which may be a thickened printing paste) in conjunction with an alkaline treatment see Specification 797,946.  They also dye silk, wool, regenerated protein, polyamide and polyacrylonitrile textile materials from weakly acid to neutral dye baths and print silk, wool and regenerated protein textile materials by conventional methods.  Yellow and orange shades are obtained.  Examples are provided of the preparation of the dyes and their use in dyeing cellulosic materials.  In the Provisional Specification A may also be a radical of the naphthalene series containing two SO3H groups neither of which is in the 8 position.

Title: Method of making a torch tip by forming a chamber in a block of material
IPC: B23P15/00
Filed: 1974-04-25
Abstract: 1462291 Making torch tips W J FUTERKO 25 April 1974 [26 April 1973] 18248/74 Heading B3A [Also in Division F4] A chamber for a torch tip is made by drilling from a first portion of a block of material at least two spaced, blind bores, drilling from a second portion of the blank at least one further blind bore so as to intersect the previously drilled bores and sealing the outer end of those bores not required for the passage of fluid into or out of the chamber formed. In one embodiment, an upper gas chamber 42 is formed within a rectangular metal block 11 by drilling spaced, blind holes 24, 26, 28, 30 from one side 12 of the block 11 and drilling from the opposite side 14 of the block 11 blind holes 34, 36, 38 which overlap the holes 24-30 in the side 12 so as to form a chamber 42 within the block 11. The outer ends of the holes are sealed by solder or plugs 44, 46. A lower chamber 58 is formed in a similar manner. The chambers 42, 58 are provided with inlets for gas, e.g. hydrogen, oxygen, propane, by leaving a hole unplugged or by drilling a communicating hole 64, 66 in the bottom 18 of the block 11. Openings 68 are drilled into the chamber 42 from the top 16 of the block 11 to provide gas outlet passages. Gas outlet passages for the other chamber 58 are provided by tubes 72. In another embodiment (Figs. 5-7, not shown), the block is drilled with communicating holes (106-116) so that when the open ends of the holes are plugged cooling water may be circulated. The chambers are supplied with gas through manifolds (120, 124) provided with spaced openings (122a, 128). Holes (130) are drilled against at least one top edge of the block and communicate with passages (134-138, 142) formed by drilling holes and plugging their open ends. Compressed air is supplied through the passages to exit through the holes (130) so as to form a gas sheet which confines the flame produced by the torch tip. Two such torch tips may be positioned on either side of a quartz or glass tube (144) (Fig. 22, not shown), so as to heat it. In a further embodiment each chamber is formed within a cylindrical block (157) (Figs. 8-10, not shown), by drilling radial holes. A circular water cooling passage (194) is formed by drilling spaced radial openings (196) and axial openings (198) between each pair of radial openings (196) and sealing the ends of the openings with plugs (200). The torch tip may alternatively be arcuate shaped (Figs. 11 to 13, not shown). In another embodiment (Figs. 14 to 17, not shown), a cylindrical torch tip of a torch for treating the inside of a tube is provided with a semicircular water cooling passage 298 and with axial gas supply passages (272, 274) communicating with gas outlet passages (280, 282) opening on to a flat rectangular area (270) formed on the side wall of the tip.

Abstract: 458,780. Altimeters. WRIGHT, G. M., Broom Hall, Bicknacre, Chelmsford, and McLELLAN, A., 30A, Peter's Court, Porchester Road, Bayswater, London. June 26, 1935, No. 18256. [Class 106 (ii)] An altimeter of the aneroid barometer type reading over a small range comprises an aneroid capsule b or the like mounted within an hermetically sealed chamber i protected from ambient temperature changes, and having a valve Q whereby it can be placed in communication with or shut off from the surrounding atmosphere. The barometer capsule and movement is of usual construction, is arranged so that full deflection of the pointer h corresponds to a change of height say of 500 or 1,000 feet and thus to have negligible hysteresis. The casing is lagged with heat insulating material j. There are two concentric scale rings k, m rotated by knobs l, n mounted outside the chamber and above the window. The outer scale k is a pressure scale in millibars, the inner scale m being marked in feet. A thermostatic switch o controls a lamp p or other heater device to maintain the temperature at a higher level than the highest ambient temperature to be expected. The instrument is fitted on an aircraft in addition to the usual instrument. Before a flight, the height scale m is rotated relatively to the outer scale k until the reading given by the' " zero " on scale m upon the scale k corresponds to the barometric pressure at the aerodrome. The scales are then rotated together keeping the relative positions unchanged, until the pointer h reads zero on the height scale m. The valve q which meanwhile has been open is now closed and the scales clamped. The instrument is now not subjected to the changing conditions during flight but when a landing is to be made, the pilot obtains by wireless, information of the barometric pressure at the landing stage and having descended to a point within the range of the altimeter, rotates the scale m until the reading of zero ' on scale m against scale k agrees with the ascertained barometric reading at the landing place. The pilot then opens valve q whereupon the height is indicated relatively to the proposed landing place. The valve may be operated automatically from the ordinary altimeter fitted on the aircraft.
