Title: Improvements in coloured textile materials
IPC: D06P1/92
Filed: 1948-02-26
Abstract: Textile materials containing both cellulose ester or ether fibres and superpolyamide fibres are coloured so as to colour the former but leave the latter uncoloured, by subjecting the materials to the action of a solution of a dye in a liquid medium which swells the cellulose ester or ether fibres without substantially swelling the superpolyamide fibre.  The dyestuff used is one which has an affinity for the nylon fibres when applied from an ordinary aqueous bath. Suitable liquid media are mixtures of water with a water-miscible organic liquid such as methyl or ethyl alcohol or other lower alcohol of 3 or 4 carbon atoms, particularly an aqueous alcohol of 55-75 per cent strength.  An inorganic thiocyanate may be present and also an organic acid such as formic, acetic, or propionic acid.  Other liquid media are mixtures of water and ketones or esters, e.g. acetone, diacetone alcohol, glycol monoacetate and ethyl lactate. Non-aqueous liquids, e.g. a mixture of ethyl acetate and xylene may also be used. Dyes specified are nitro-diarylamines, azo dyes, amino-anthraquinone dyes and acid dyes.  After treatment by the above process the superpolyamide fibres may be dyed with dyestuffs having little or no affinity for cellulose acetate, either in the same or in a contrasting shade.  In examples: (1) a fabric having a cellulose acetate weft and a nylon warp is dyed in an aqueous bath containing methylated spirit, acetic acid, sodium thiocyanate, 1-phenylamino-anthraquinone and 2-nitro-4-chloro-diphenylamine to dye the acetate and then the nylon is dyed from an aqueous bath containing Naphthalene F Red BNS, Lissamine F Yellow 2GS and formic acid to produce the same shade on both fibres; (2) a fabric containing cellulose acetate and nylon yarns is dyed in an aqueous bath containing methylated spirit, acetic acid, sodium thiocyanate and Croceine Scarlet 3BS, and the nylon yarns may then be dyed, e.g. as in (1); (3) a fabric containing cellulose acetate and nylon yarns is dyed in an aqueous bath containing methylated spirit, acetic acid, sodium thiocyanate and Solacet Fast Blue 2BS and the nylon then dyed, if desired, as in (1); and (4) a fabric containing cellulose acetate and nylon yarns is dyed in an aqueous bath containing diacetone alcohol, ammonium thiocyanate and Artol Blue B.  Specification 594,722 is referred to.

Title: A method of treating acid tars from the purification of benzole or other liquid hydrocarbons for the recovery of acid, resinous and other bodies
IPC: C01B17/92
Filed: 1933-02-27
Abstract: Acid tars, formed in the refining of benzole and other hydrocarbons with acid, are passed into water maintained at boiling point during admission of the tar, whereby acid hydrocarbons and resin are recovered therefrom.  A suitable treating tank is provided at one side with a channel or partition the lower end of which opens below the surface of the boiling water contained in the tank.  The water is maintained boiling by a steam heating coil or by a pipe admitting live steam.  In operation, sulphuric acid sludge is poured in a thin stream down the channel and mixes with from \ba1/2\be to 1 volume of boiling water, whereby the sludge is rapidly diluted and the formation of charred bodies or sulphur dioxide is prevented. Hydrocarbons distilled off are condensed by water cooled tubes mounted at the top of the tank below which is mounted a tray to collect the condensate.  Alternatively a condenser may be mounted on the lid of the tank.  The layer of resins floating on the solution of diluted acid is drawn off and treated for 2 to 3 hours with steam, or may be removed and treated with aqueous ammonia or alkali and worked up into hard resin.  The acid layer containing up to 75 per cent by weight of sulphuric acid and free from organic matter, is drawn off at the bottom of the tank and is concentrated.ALSO:Acid tars, formed in the refining of benzole and other hydrocarbons with acid, are passed into water maintained at the boiling point during admission of the tar.  The layer of resin floating on the diluted acid is drawn off and treated with steam or with aqueous ammonia or alkali, and worked up into a hard resin.  Apparatus is described.

Title: Improvements in or relating to control mechanism for the wheel brakes of aircraft
IPC: B64C25/48
Filed: 1940-04-03
Abstract: 538,460. Aircraft wheel brakes. DUNLOP RUBBER CO., Ltd., and TREVASKIS, H. April 3, 1940, No. 5990. [Class 4] Fluid-pressure operated brakes on the main and nose landing wheels of aircraft are adapted to be uniformly applied by operation of a common control member and, by operation of a second control member in conjunction with the first, the brakes on the nose wheel and one of the main wheels can be applied to a less extent than that on the other main wheel. The second control member may be the rudder bars. A control unit 1 for the main wheel brakes and constructed substantially as described in Specification 525,266 is connected to a control unit 2 for the nose wheel brake by a top plate 3 provided with pipe connections 4, 4a for the compressed air supply. The valve-operating elbow links of the unit 1 are operated by a pushrod 7 instead of by a cable as in the prior mechanism and this rod is connected by a bellcrank 8, link 13 and bell-crank 12 to a push-rod 11 which operates the pair of valves in the unit 2. The brakes on all the wheels can thus be equally applied by a cable 10 attached to the lever 8. The unit 2 is provided with a camshaft 20 adapted to regulate the pressure applied to the nose wheel brakes by means similar to those by which the cam-shaft 19 of the unit 1 effects differential braking of the main wheel brakes. The shaft 20 is operated from the shaft 19 by a slide plate 14 having a slot 17 engaging a pin on an arm 18 on the shaft 20, and a cam slot 16 engaged by a pin 21 on an arm on the shaft 19. Operation of the shaft 19 by a connection from the rudder bar to an arm 15 on the shaft thus reduces the pressure applied to the nose wheel brake irrespective of the direction in which the shaft 19 is turned and to an extent determined by the cam slot. The arrangement may be such that when the rudder bar is fully deflected the nose wheel and one of the main wheels are not braked while in an intermediate position of the bar the pressure applied to the nose wheel brake is less than that applied to the main wheel that is on the inside of the turn. Specification 507,162 also is referred to.

Title: Glass tempering processes and apparatus
Inventor: LAETHEM ROBERT VAN
IPC: C03C21/00

Abstract: 1,208,153. Tempering glass or glass-ceramic. GLAVERBEL. 8 Feb., 1968 [27 April, 1967], No. 6390/68. Heading C1M. Glass or glass-ceramic material is tempered by heating to bring at least its internal layers to a temperature above the strain point whereby an ion-exchange takes place between the heated material and a contacting medium, which is preferably in the form of a coating, so that compressive stresses are set up in the surface layers, and after the ion-exchange has occurred, the material is rapidly cooled to cause compressive surface stresses also to be set up due to the surface layers cooling more rapidly than the internal layers. The surface layers of the glass, in particular, soda-lime glass, are heated above or below the strain point according to whether smaller or larger ions, respectively, are substituted into the glass. In one embodiment lithium ions are caused to replace sodium ions in a sheet of soda-lime glass coated with a fused lithium salt by heating to a temperature above the annealing point and then cooling to below the strain point. In another embodiment potassium ions replace the sodium ions in the glass by heating the coated glass by thermal radiation to raise the temperature of the internal layers above the strain point, while the temperature is kept below the strain point by contact with a heated gaseous medium. Heating means include electrical resistance heaters or surfaces heated to incandescence by combustion of a gas. Soda-lime glass can be irradiated with infra-red radiation of wavelengths below 2.8 microns. As shown the apparatus may comprise a tank 1 containing a bath 7 of molten salt, an oven 2 equipped with gas-heated radiant heating elements 12, and a cooler 3 equipped with cooling air ducts 14 with nozzles for discharging jets. of cold compressed air. Articles 15 to be treated are attached at station 17 to an endless conveyer 16 which follows a cyclic course through the tank, oven and cooler, and are removed at station 18.. In another type of apparatus, hot air is blown into the bottom of the oven through pipes and withdrawn from the top.
