Abstract: 623,548. Electrodepositing layers of metals. BIRMINGHAM SMALL ARMS CO., Ltd., and OLIVER, D. A. March 14, 1946, No. 7916. [Class 41] [Also in Groups XII, XXII and XXVI] Hollow metal articles intended to be subjected to high temperatures such as hollow blades or flame tubes for gas turbines are made by electrodepositing successive layers of metals such as nickel, chromium, cobalt, iron, molybdenum, tungsten, zirconium, niobium, tantalum, titanium, vanadium or manganese, on a thermoplastic former such as dental wax, Rose's metal or Wood's metal or a former of friable material such as porous plasters, cements or unglazed porcelain and then removing the former as by heat or disintegration and subjecting the article to high temperature treatment to cause interdiffusion of the metals. A layer may be composed of cobalt and nickel deposited simultaneously to form a homogeneous binary. In an example, the successive layers may be chromium and nickel or chromium, nickel and cobalt or nickel, chromium and a homogeneous binary of nickel and cobalt. In the formation of a flame tube, a layer of copper forms the substratum for the subsequent layers, for example the layers may be copper, nickel, chromium, nickel and cobalt. At an intermediate stage and at the final stage of electrodeposition, the article may be subjected to a carburizing or nitriding operation.

Abstract: 1,159,635. Collapsible louvre assemblies. A. STOEVER 20 Feb., 1968 [21 Feb., 1967], No. 8100/68. Heading E1J. In a collapsible louvre sunblind or other louvre assembly for horizontal or vertical collapse the turning of the louvres about their central axes and their movement bodily to the same draw-mechanism through a lost motion clutch device. As shown .the shank 4a of a slot or louvre attached to the slat holder 4 has thereon a toothed rim sleeve 13 which engages with a worm nut 11 provided with internal helical teeth 12 which rotate the axially fixed nut 11 on rotation of the threaded spindle 8, to rotate the louvre about its longitudinal axis. The end of the shank 4a has a diverging conical portion 15 and a collar 16 with a corresponding conical interior is displaceably arranged at the lower end of the shank 4a and is urged against the portion 15 by a compression spring 14 and prevented from rotation on the shank by a projection 16a located in a groove 13b on the interior of the sleeve 13, the whole being mounted in a hollow in a carriage (Fig. 5) 6 adapted to run by rollers on a lower guide track, and similarly on an upper guide track. A transverse pin 18 contacts stops 19, 20 and prevents rotary motion of the shank 4a and the continued rotary movement of spindle 8 is converted through teeth 12 and nut 11 into bodily shift movement .of the shaft 4a and slat along the spindle 8. The carriages are interconnected by pivoted link bars which maintain equidistance between the carriages and prevent the locking alignment when in their closed position. When the carriage is of open top form (Fig. 3) flexible dust excluding strips close the opening, allow movement of the shanks 4a along the guide.

Thus the beam may be of shallow C crosssection or as shown tray elements may be bonded back-to-back by adhesive 8, optionally with the interposition of a metal honeycomb or foam plastics layer (Fig. 2A not shown), to form an I-beam. If three-sided trays are used a T cross-section beam is produced. The trays are preferably formed by moulding of two or more layers of mainly. unidirectional-fibred plastics, alternate fibre layers being placed with their fibre directions at opposed equal angles to the longitudinal axis 4 of the beam along which the fibres of the capping layer 7 are directed. For curved beams the trays are toroidal segments in plan (Fig. 3 not shown) while cranked beams include trays which are of trapezium form with unequal parallel sides (Fig. 4 not shown). When intersecting beams are employed the web of one beam is interrupted and the ends of the trays forming this beam are stepped downwardly as at 11 (Fig. 5) to accommodate the chords of the I-beam 10 which also may be formed in accordance with the invention.

Abstract: A tinting shampoo comprises a composition obtained by reacting a mono- or poly-hydroxy naphthoquinone with at least one molecular proportion of an aliphatic thiol substituted with a hydrophilic group in aqueous or aqueous-alcoholic solution and also contains a detergent unreactive towards the reactants and the products of the reaction.  The shampoo preferably has a pH of 3-10 and the detergent usually comprises from 10 to 40% by weight of the shampoo.  The detergent may be a cationic, anionic or nonionic surface-active agent or a mixture of such agents but when a thiol carboxylic or sulphonic acid is used the detergent should not be cationic and when a basic thiol is used the detergent should not be anionic.  Detergents specified are alkyl sulphates such as sodium lauryl sulphate and diethanolamine lauryl sulphate and mixtures of triethanolamine lauryl sulphate with coco-diethanolamide condensate, alkyl aryl sulphonates such as the triethanolamine salt of dodecyl benzene sulphonate, the sarcosides, the fatty acid imidazolines and polyglycol ethers of alkyl phenols.  In an Example (7) a composition is made by treating 5:8-dihydroxy-1:4-naphthoquinone with thioglycollic acid, adding triethanolamine lauryl sulphate and lauric diethanolamide and diluting with water.ALSO:A composition for dyeing keratinous fibres including hair is made by reacting a mono- or poly-hydroxy-naphthoquinone with at least one molecular proportion of an aliphatic thiol substituted with a hydrophilic group in aqueous or aqueous-alcoholic solution.

[Class 40 (v)] A combined carrier generating and modulating arrangement comprises a diode-triode type valve. Associated with the triode electrodes 11, 12, 13 of the valve 10 for operation as an oscillation generator are the tuned transformer 17 coupling condenser 20 and grid leak 21. The diode electrodes 15, 16 are connected in push-pull with transformer 22 to form a balanced modulator circuit, the modulating signals from amplifier 30 and filter 32 being applied across an impedance 25 connected between ground and the mid-point of winding 24 or the tapping of a resistance connected across the winding. Carrier frequency is supplied by condenser 26 to one end of winding 23 or 24 and the modulation products appear across winding 23 of the transformer 22. Filter 28 may select only one of the side-bands for transference to amplifier 31. If the lower side-band is selected and the carrier frequency is of the correct value, the result will be frequency inversion of the modulating signal. After transmission by modulating the inverted signal on a carrier, the signal may be re-inverted at the receiver by a circuit similar to that shown in the Figure,

Abstract: 925,776. Yeast; yeast for foods and feeds. SVENSKA SOCKERFABRIKS A.B. March 9, 1961 [March 17, 1960], No. 8693/61. Classes 14 (2) and 49. Yeast cells valuable as a nutrient, e.g. for admixture in food, as a raw material for the drug industry or for breeding poultry, are produced by preparing a substratum of potatoes or potato waste and fermenting the substratum with starch-hydrolysing yeast belonging to the group Endomycopsis of the sub-family Saccharomycetoideae of the family Saccharomycetaceae in symbiosis with sugar fermenting yeast, such as Torula and Saccharomyces. According to an example, potatoes sterilized by steam in a vessel 1 are passed through a mill 3 to a mixer 5 to which there is supplied also water, ammonium sulphate solution or other nutrient (such as solutions containing ammonium nitrate or superphosphate) rendered sterile by a filter 8. The potato mash obtained is delivered at a temperature of about 30‹ C. partly to a precultivation vessel 11 (or several of these) and partly to a number of main cultivation vessels 12a, 12b, 12c. Each of these vessels has an agitator 13, a cooling coil 14, a dispersing nozzle 15 connected to a conduit for compressed air, and means (not shown) for suppressing foam, supplying steam, and temperature and pressure measurement. In the pre-cultivation vessel 11 the potato substratum is inoculated with a culture of Endomycopsis fibuliger and after a sufficient number of yeast cells has been formed, a portion of the culture thus obtained is transferred to each of the cultivation vessels; in these vessels saccharification is achieved employing Torulopsis yeast. The yeast substance is separated from the fermentation liquids in the units 20a and 20b, is stored in a cooling tank 21, then is dried (22) and ground (23). 1000 kg. potatoes will yield about 100 kg. yeast.
