Title: Improvements in and relating to automatic tube testing means
Inventor: GORSKI WOJCIECH
IPC: G01B13/10
Filed: 1960-07-15
Abstract: 986,841. Pneumatic gauging. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 13, 1961 [July 15, 1960], No. 24761/60. Heading G1M. A gauge for testing the diameter of a tube t comprises a feeler b whose cross-section is equal to the minimum allowable cross-section of the tube bore. Pressure fluid from a reservoir SP flows through an orifice C into a sleeve S and through the area between the feeler b and tube t, the rate of flow being proportional to the area. Hence, the pressure in the sleeve S depends on the cross-section of the bore. When this cross-section exceeds a given maximum, the pressure drops to operate a switch e responsive to the pressure difference between the sleeve Sand reservoir SP. If the crosssection of the bore of tube t is less than that of the feeler b, the feeler is displaced as the tube t is advanced and a switch m 2  is actuated. A member g is provided which is displaced by bends in the tube as it enters the sleeve S, to operate a switch m 3 . A further switch m 1  is provided to disconnect the other switches when required. The tubes may be sorted according to the results of the gauging operations.

Title: A method for the utilisation of manganese ore for the production of pure manganese sulphate and the regeneration of the sulphate spent liquid from electrolytic manganese and manganese dioxide baths
IPC: C01G45/10
Filed: 1953-09-08
Abstract: Manganous sulphate is produced from manganese containing ores by digesting the ore in sulphuric acid of up to 10 per cent by weight strength or in spent liquor from electrolytic manganese or manganese dioxide baths, with one or more organic reducing substances in the same vessel, the digestion being carried out by heating to 100 DEG C. or above at atmospheric or increased pressure, preferably at the boiling point, to obtain a pure manganous salt or regenerated liquor suitable for electrolytic manganese production.  The organic reducing material employed may be aldehydes, carbohydrates comprising mono-, di- or tri-saccharides or polysaccharides including glucose, sucrose, molasses or, preferably, sawdust.  The sawdust may be pre-treated with acid or alkali to remove water soluble substances and equal amounts of ore and sawdust are preferably employed.  The digestion is preferably effected in two stages in the first of which crushed ore with approximately sufficient free acid to neutralize the ore together with sawdust is digested under reflux for 5 to 9 hours and the solution filtered, and passed to the second stage where the solution is employed for the treatment of fresh manganese ore which is added to the solution.  The mixture is then digested under reflux for 6 to 9 hours until the acid has been utilized and the pH brought to 5.6.  The pH is then adjusted to 6.4 to precipitate impurities such as iron or phosphorus, after which the solution is filtered to remove residual organic matter

Abstract: 201,444. Jackson, W. J. Mellersh-, (Libbey-Owens Sheet Glass Co.). Sept. 16, 1922. Drawing.-Relates to the process of drawing sheet glass, described in Specification 114,977, in which the sheet is drawn vertically upwards and is then passed over a bending-roller, whence it proceeds horizontally. The bending-roller has a very smooth surface which eventually becomes tarnished and must then be replaced. The present invention consists of a method of replacing the bending-roller by another without interrupting the production of sheet glass. Construction. The bending-roller 5, Fig. 1, is journaled at its ends in bearings 9 which are hung from adjustable supports 10 at the sides of the tank. The device for changing the rollers consists of members 11 which can be wheeled to the sides of the tank and locked in position. Each member 11 supports a short shaft 16 to one end of which is keyed a double bracket 17, Figs. 1 and 3, while at the other is secured a gear-wheel 18 that can be rotated by a hand crank 21. The bracket 17 carries at its end studs 22 on which bearing-rings 23 are freely rotatable, and the bearing-rings fit into the ends of the bearing- roll 5. Operation. In changing a roll, the member 11 is run up to the sides of the tank and locked in place with a ring 23 fitted into the end of the roll 5, as shown. The new roll 5<1>, which has been heated to the correct temperature, is brought parallel with and beneath the roll 5, but not in contact with the sheet 1, the end of the roll being fitted on to the second ring 23. The second member 11 is then fitted to the other ends of the rolls 5, 5<1> and locked in position. The bearings 9 are then freed from the supports 10, and by turning the cranks 21, the brackets 17 can be turned through 180‹ and the rolls interchanged. The old roller is then removed.
