Title: Textile colouring emulsions
Inventor: PAUL JULIEN
IPC: D06P5/15
Filed: 1958-01-27
Abstract: A textile colouring emulsion has an inner phase consisting essentially of a volatilizable hydrocarbon oil and an outer water phase containing, in solution, a water-soluble formaldehyde-sulphoxylate and a water-soluble caseinate or soya-bean proteinate or mixture of both.  The water phase may contain 0,0375-2,25 %, especially 0,075-0,45% of the caseinate or proteinate, the percentages being by weight, on a dry basis, based on the weight of the emulsion.  From 4-20% by weight, based on the weight of the emulsion, of water-soluble formaldehyde sulphoxylate may be present and the relative proportions of the oil and water phases may be 25-45% and 75-55% by weight respectively.  Alkali may be present in the water phase, especially 2-12%, based on the weight of the emulsion, of e.g. sodium and potassium hydroxides or carbonates, or amines such as triethanolamine.  The water phase may also contain hygroscopic agents (e.g. glycols, urea) dispersing or wetting agents (e.g. ethylene oxide condensates, sodium lignin sulphonates), thickeners, (e.g. sodium alginate, carboxymethylcellulose, guar gum), preservatives (e.g. sodium #s-phenyl phenate), catalysts (e.g. anthraquinone) and whitening agents (e.g. titanium dioxide). Sodium alginate may be present in the water phase in the proportion of from 2,4 to 3,1 parts by weight of alginate to 0,56 to 3,75 parts by weight in total of caseinate and soya bean proteinate.  The emulsion may be prepared from an aqueous concentrate containing 0,56-3,75% by weight in total of caseinate and proteinate, on a dry basis, based on the weight of the concentrate, and from 2,4-3,1% by weight on the same basis of sodium alginate.  The other water-soluble constituents, and water, are added to the concentrate in the amount required to produce the final emulsion and the resultant solution is emulsified with the hydrocarbon oil.  Vat dyes may be incorporated in the emulsion, to form a paste containing preferably not more than 30% by weight vat dye and at least 70% oil-in-water emulsion. The paste may be used in both application and discharge printing.  The caseinate or proteinate is said to inhibit oxidation of the reducing agent in the paste.

Filed: 1921-01-22
Abstract: 172,548. Platt, W. H. H. Jan. 22, 1921. Drawings to Specification. Soldering.-Relates to repairing sheets and castings of aluminium and its alloys and to the attachment of copper, brass, steel, and other metals to aluminium, and consists of tinning, sweating, and burning processes. An alloy which fs used in the tinning or sweating process consists of approximately 2 parts of tin, 1 part of zinc, and i part of aluminium, which are melted together and run into thin strips. The casting to betreated is cleaned in any ordinary way, and then rubbed with a file or scraper, and then heated in a blow-lamp and a strip of the alloy, without a flux, melted on to the part to be repaired, and worked by a scraper &c. into the crack or hole to be filled. The lamp is then withdrawn and the plastic alloy can be worked into any desired configuration. To attach a brass or copper article to a part of aluminium, the article is first tinned with block tin, using killed spirits, or sal-ammoniac, and washed in hot water to remove all traces of acid. It is then tinned with alloy and allowed to cool. The aluminium casting is then tinned with the same alloy and when both parts are cool they are placed together and a sweated joint made between them. To attach a steel tube to an aluminium casting, the part of the tubeto be jointed is filed or cleaned with emery cloth or hydrochloric acid. This part is then tinned with block tin as described above, and when clean retinned with the alloy and the aluminium cast on to it.

Filed: 1924-02-05
Abstract: 223,793. Odell, W. W. Feb. 5, 1924. Producers; producer plant.-A gas producer for use on motor vehicles comprises a fuel hopper of large capacity, means for working by up or down draught, an easily replaceable fuel container suspended by cushioned supporting-means within the shell, and means for generating steam and preheating the blast before entering the fuel bed. Fuel from a hopper A fills a fuel pot D resiliently suspended on packing-rings E, E' and gravitates on to a base X from which ashes are removed through a door R. Moistened air entering by a pipe F is preheated in the space C and, according to the position of the, lever J and valves K, L, passes either to the top or bottom of the fuel bed, the gases escaping through either of the outlets H, G according to the position of the valve I which is coupled to the lever J. Liquid hydrocarbon from a tank T may be supplied to the fuel bed to accelerate the production of gas after a stoppage. The gas passes through a dip pipe v in a water seal m and is filtered and cooled by passage through glass wool, mineral wool or other filling in a chamber s before escaping through a pipe k. Water from a reservoir f is caused to trickle over absorbent material h arranged around the shell c. The air enters the flared inlet a under pressure due to the motion of the vehicle, the inlet a facing the direction of travel through the spiral passage in the casing b before reaching the pipe e leading to the producer.

Abstract: 1350901 Testing ferromagnetic sheet for uneven rolling BRITISH STEEL CORP 19 April 1971 [21 Jan 1970 2 Sept 1970] 3039/70 and 42073/70 Heading G1N Cold-rolled steel sheet is tested for apparent and latent disconformities such as "long edges" and "long middle" by passing it over a pair of spaced supports defining a datum plane, attracting it with a magnet arranged between the supports above or below the datum plane, and sensing the resulting deflection of the sheet. The testing station may be situated between the final work rolls (2) and a billy roll (3), said rolls acting as the spaced supports. In Fig. 2, three D. C. electromagnets 11, 12, 13 interspersed with inductive sensors 15, 16, 17, 18 are arranged across the width of the sheet. Each sensor comprises an H core (or two U cores back-to-back), energizing windings 20, 21 and a centre tapped pick-off winding 22. A dummy sheet 23 may be arranged in the lower magnetic circuit so that the pick-up winding responds only to deflections of the sheet from the datum plane. The output of each sensor is fed via a tuned transformer filter (24-27), Figs. 3 and 4, (not shown) to reject mains frequency, buffer amplifier (28-31), preferably phase detector (33-33c), and a scanning switch (32) to a display tube 10. The current fed to each electromagnet may be controlled to give a constant deflection across the sheet, and Hall effect devices used to detect the magnet fields. A permanent record may be made. The work rolls may be controlled. The displacement sensors may be capacitive.

Mixing powders comprising iron together with carbon 0.3-0.4 per cent., chromium 1.5-2 per cent., nickel 4.5-5 per cent., and copper 3.0-3.5 per cent. are compressed in a steel die around the pin at a pressure of from 10 to 50 tons per square inch and the compact is then sintered in a non-oxidising atmosphere at a temperature of from 1,000‹C. to 1,350‹C. The surface of the pin may be plated to facilitate bonding and a ring of copper may be placed around the projecting end of the stud after compacting but before sintering, so that the copper will diffuse into the adjacent surfaces of the materials of the pin and holder. Specification 480,147 is referred to.

Abstract: 759,190. Cutting by spark discharge. WICKMAN, Ltd. Jan. 5, 1955 [Feb. 3, 1954], No. 3189/54. Class 83 (4). In an electro-erosion apparatus in which the spark passes through a liquid dielectric between the electrode f and the workpiece g and the feed mechanism is responsive to the voltage or current across the spark gap, the electrode is vibrated by means including a cam n in order to cause a localized pumping action on the liquid dielectric between the electrode and the workpiece and thereby disperse detached metal particles from the spark path. The electrode is attached to a quill h mounted in a slide b movable on a guide a by a feed-screw c rotated through gearing d by a motor e whose speed is controlled by the voltage or current in the sparkgap between the electrode f and the workpiece g. The quill is movable towards the workpiece by a spring k and away therefrom by a lever m actuated by the cam n which is rotated through gearing o by a constant-speed motor p. The electrode is retracted by the cam at a rate greater than that at which the feed mechanism can respond to the charge of spark voltage or current during such retraction. In a modification the electrode is moved towards the workpiece by the cam and away from it by the spring. In another modification both movements are effected by the cam, one end of the arm m engaging a track in the cam.
