Abstract: 432,499. Maintaining defined speeds of motors. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London, POOL, W. J., Chelmsley, Barby Lane, Hillmorton, near Rugby, and GIVEN, R. D., 33, Russell Terrace, Leamington, both in Warwickshire. Jan. 27, 1934, No. 2861. [Class 38 (iii)] Means for winding a web upon a reel at substantially constant speed comprises an alternating current commutator motor driving the reel having brush-shifting means actuated in accordance with any difference between the speed of the web and a constant speed. A roll in contact with the web actuates through a variable gearing 8, 9 one element of a differential gear, a constant-speed electric motor 6 actuates a second element thereof and the third element 7 is coupled to the brush gear of the driving motor 5 so that the speed of the winding roll 4 is progressively changed as the winding diameter increases and the speed of the web remains constant. In a machine wherein the web is being unwound from a reel 2 at the same time, an alternating current commutator motor 11 is controlled to give a like speed of the web by connecting its brush gear to a counterweighted tension-compensating roll 14, determining the tension in the web.

IPC: G01N21/37
Filed: 1959-01-27
Abstract: 871,726. Infra red gas analysis. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 19, 1960 [Jan. 27, 1959], No. 2909/59. Class 40(3) [Also in Group XL(a) ] A carbon dioxide cooled nuclear reactor of the kind having a moderator penetrated by channels charged with fuel elements is provided with means for comparing the general carbon monoxide content of the coolant with the carbon monoxide content of coolant emerging from selected channels. The apparatus shown in the drawing comprises an infra-red gas analyser having two infra-red radiation sources 1 from which radiations pass through two tubes 2a, 2b containing the gases to be compared into a pair of detection chambers 3 containing pure carbon monoxide. The tube 2a is connected by a rotary selector valve 7 to each fuel channel or group of fuel channels in turn whilst the tube 2b is connected to the main coolant outlet duct; the two tubes 2a, 2b are connected by a pressure balancing bleed pipe 16, and the exhaust from the tubes is returned to the reactor. In operation the gas in chambers 3 is heated by radiation passing through tubes 2a and 2b, and the chopping of the beams by shutter 5 causes pressure pulses in the chambers which are equal so long as the gases in the tubes are equal. An increase in the carbon monoxide in tube 2a such as might be caused by a fire in a fuel channel causes one of the chambers 3 to be heated less than the other and the diaphragm 4 separating the two chambers oscillates; this oscillation is detected electronically and can be correlated with the relative changes in carbon monoxide content in tubes 2a, 2b.

Title: New metalliferous azo-dyestuffs and process for making them
IPC: C09B35/16
Filed: 1954-02-05
Abstract: The invention comprises dyestuffs which in the free acid state are of formula <FORM:0756190/IV(c)/1> where Me is Ni or Cu, X is O, COO or OCH2COO and R1-O and R2-O are residues of naphthol monosulphonic acids bound to the azo linkage in ortho-position relatively to the O-Me group, and where at least one of the latter residues contains a HO-O2S-O-alkylamino group the amine nitrogen atom of which is directly attached to the naphthalene nucleus of R1 or R2.  They may be made by treating the corresponding metal free dyestuff where in the free acid state X is OH, COOH, OCH2COOH or HO SO2 O with agents yielding nickel or copper.  The metal free dyestuffs may be made by coupling the appropriate tetrazotized diamines and naphthol sulphonic acids at least one of the latter containing an oxyalkylamino group advantageously of low molecular weight, e.g. an ethyl, propyl or butyl residue, which is converted into a HO-O2S-O- alkylamino group by treatment with chlorsulphonic acid in the presence of a tertiary-base, e.g. picoline or pyridine; or with concentrated sulphuric acid.  During treatment with chlorsulphonic acid aromatically bound OH groups may be esterified.  Diamines specified are 3, 31-dioxy- and -di-(carbomethoxy) -4, 41-diaminodiphenyl and 4, 41-diamino-diphenyl - 3, 31 - dicarboxylic acid. Especially valuable are naphthol sulphonic acids of formula <FORM:0756190/IV(c)/2> where n is 1 or 2 and the amino group is in a b  position of I. Specified naphthol sulphonic acids are 2 - (b  - oxyethyl) - and -(di - b  - oxyethyl) - amino - 8 - naphthol - 6 - sulphonic and - 5 - naphthol -7 - sulphonic acids and 2-(b - and g -oxypropyl)-, -(oxybutyl) - and - (b 1g  - dioxypropyl) - amino 5 - naphthol - 7 - sulphonic acids, 1-naphthol - 4 - sulphonic acid, 2 - naphthol - 4 - and - 6 - sulphonic acids, 2 - amino-, -phenylamino-, - acetylamino - and - benzoylamino - 5 - naphthol - 7 - sulphonic acid and 2 - amino - 8 -naphthol - 6 - sulphonic acid.  The metal dyestuffs are used particularly for dyeing cellulose-containing fibres, e.g. linen, cotton, artificial silk and regenerated cellulose.  Examples and a table are provided showing the use of certain of the above specified components in the preparation of metal dyes which dye cotton in blue shades, 1 - (b  - oxyethyl) - amino - 8 -naphthol - 4 - sulphonic acid being an additional coupling component used.

[Classes 83 (ii) and 83 (iv)] [Also in Group XXXIII] Brazing.-In making hollow propeller blades, a tube, in which the cross-section and thickness varies along the length, is coated internally with brazing metal at the end which is to form the tip, and the end is-heated to a temperature equal to or above the fusing temperature of the brazing metal. The opposite sides of the tube are then forced into contact so that the tip is closed by a brazed joint. A propeller tube 10, Fig. 2, is shown partly completed, having an internal coating 11 at the tip end, the inner surfaces of which meet to form the brazed joint when pressure is applied, after heating. In a modification, a fillet 13, Fig. 5, similarly coated with brazing metal may be fitted into the tube so that it fuses the inside lining metal of the tube when the joint 12 is made. Coating may be applied as described in Specification 584,904, [Group II], by immersing the tube in a solution containing one or more chlorides of the metal being deposited for brazing or by immersing the' tube in a flux to remove oxide and then dipping in a molten bath of the brazing material.
