Abstract: 915,332. Thermal switches; fluid actuation of switches. BRITISH THERMALLY CO. Ltd. June 29, 1961 [May 23, 1960], No. 18106/60. Class 38 (5). An electric switch comprises a lever 6 acted on by a temperature or pressure-responsive element 1 and acting on means to change over switch contacts 20-22, a range spring 8 and a differential spring 11 also acting on the lever, both being adjustable from the same side of the apparatus. A bellows 1 containing low-pressure air acts as the temperature-responsive element. Falling temperature causes pull-rod 4 to rotate the lever 6 about a pivot 7 against the range spring 8 and the contacts change over under the influence of a snap-action spring 18. Towards the end of its motion the lever 6 engages a screwed stud 13 biased towards the lever by the differential spring 11 acting on a sliding collar 12. The position of the stud 13 is initially adjustable by movement relative to the collar 12. In the pressure-actuated form of the switch (Fig. 2, not shown) the pressure is applied to the interior of the bellows 1.

Title: Acid pasting of phthalocyanine pigments
Inventor: BROUILLARD ROBERT ERNEST
IPC: C09B67/16
Filed: 1952-07-17
Abstract: Phthalocyanines are produced in finely divided form by kneading 1 part of pthalocyanine pigment with 2-5 parts of sulphuric, chloracetic, phosphoric, chlorsulphonic or alkyl sulphonic (e.g. methyl or ethyl sulphonic) acid of a concentration from 68 to 100 per cent and sufficient to produce a kneadable mass, the mass being subsequently drowned in water.

Abstract: 705,304. Printing-machines. COATES BROS. & CO., Ltd., and MATHEWS, A. C. B. July 24, 1952 [Aug. 2, 1951], No. 18348/51. Class 100 (2). [Also in Group XIII] Drying-apparatus.-In apparatus for drying ink on webs in which a hot gas which contacts the web to dry it is circulated in an endless circuit, the hot gas is obstructed in its passage when the web is at rest and flows instead through a shortcircuiting path. The web 1 passes over a horizontal rotatable drum 2 which has a hot shroud 3 covering its upper part and blowing streams of hot gas against the web. The shroud 3 comprises a series of ducts 5 extending between gas chests 6, having slots 7 through which the gas is delivered and covered by a cowl 8 from which leads an outlet conduit 9, the chests 6 being supplied by conduit 10 having branches 11. Hot gas from a gas-fired furnace 14 is passed by a fan 15 through conduits 16, 17 to the shroud 3 thence from outlet 9 to conduits 18, 19, 20, 21 back to the fan, fresh hot gas being fed to the circuit by way of a duct 22 from the atmosphere, passing through furnace 14 and moist gas bleeds to the atmosphere at 23 through duct 24, this duct having a gravity biased damper 25 which opens under pressure. The system also has a short circuiting duct 33 having a damper 34 open when the web stops and when the web stops running cut-off dampers 26, 27 isolate the main circuit and the gas passes through conduit 33, a cooling fan 28 blowing cold atmospheric air through conduit 29, the shroud 3 and outlet conduit 30 which has a lightly biased damper 31 normally closed, aided by the fan suction. The conduit 29 has a damper 32 opened by a time switch control so that the shroud is not completely chilled. Damper 26 in its closed position does not completely cut off the hot gas flow and when the pressure caused by fan 28 ceases a small quantity of hot gas flows through the shroud. The furnace 14 is controlled by valves 36, 37 operated by thermostats responsive to the temperature in the main circuit at 36P and the shunt circuit at 37P respectively. The dried web passes over a cooling roller 4. The drum 2 has a pimpled surface to reduce heat exchange between it and the web, and in a modification it may be heated as well as the shroud. The furnace may be oil fired or electric instead of gas fired and instead of a cooling roller 4 the fan 28 may be arranged to blow cold air on the web as it leaves the apparatus.

Heading B2P A centrifuge for separating aerosals or liquid or gaseous mixtures, e.g. isotopes, into components of different specific weights comprises a holder member driven at a high rotary speed and carrying a number of nozzles 8 arranged in series and each having on its entry side edges 11, 12 to collect the core of the mixture stream leaving the preceding nozzle and to feed it to the respective following nozzle, the mixture being supplied to the innermost nozzles through a sleeve 16 and the separated mixture components being discharged through outlets 21, 22. The nozzles 8 are arranged in spiral or, as shown, in radial form between discs 4, 5 which are spaced from discs 3, 6 on a hub 2 secured to a shaft 1 supported in air bearings and driven at speeds of 10,000 to 400,000 r.p.m. or above. Alternatively, the nozzles may be formed by the discs 4, 5 which are shaped accordingly or they may be arranged in a spiral duct. Each nozzle 8 consists of two rings 9, 10 pointed on their inner side to form the edges 11, 12 and spaced apart to form a narrow slot A having a width of 1-20 Á or above. Openings 13 are formed in the discs 4, 5 connecting the space between the discs 4, 5 with discharge passages 14, 15 leading to the outlets 22. In operation, the mixture is fed continuously to the sleeve 16 and as a result of centrifugal force passes through the innermost nozzle formed by a flange 17 on the sleeve and a disc 18. A spreading of the stream occurs beyond that nozzle, the core of which containing the heavier components is collected between the edges 11, 12 of the first nozzle 8 to be fed after further spreading to the second nozzle 8 and so on in stages, for further separation, to the last nozzle 21 and to the outlet 21. The separated outer part of the stream, containing the lighter components, is led away outwardly at each nozzle by the surfaces 19, 20 and pass through the openings 13 into the passages 14, 15 for discharge through the outlets 22.

The benzene ring A can be fused to another benzene ring and the Y-O group is in ortho- or para-position to the azo bridge. The dyes are prepared by treating a compound of formula wherein X is amino or halogen, with an esterifying or etherifying agent to produce a compound of Formula I and if X is halogen, followed by reaction with an amine. Alternatively, a compound of formula may be reacted with a halogenating agent and the sulphonic acid halide so produced converted into the required amide. The dyes may also be obtained conventionally by successive diazotization and coupling. The dyes give orange and red shades on a variety of textile materials and are particularly used for the spin-coloration of cellulose esters.
