The invention comprises a method of recovering germanium values wherein a dust-free gas containing a germanium value at low concentration is contacted with a humic acid or humic acid salt, either as such or in peat, lignite or coal, which is activated to chemisorb the germanium value, which is subsequently removed from the absorbent. The absorbent is preferably moistened with an aqueous solution of pH 4 to 5. The metal value may be removed from the absorbent by combustion or by elution with an aqueous solution of pH about 7 to 8, or with chloroform or ether. The absorbent may be used in a single container or in grouped containers connected in series or parallel, and the gas may be drawn or forced therethrough. Activation of the absorbent is effected by heating in a reducing atmosphere and treating with lime or baryta water.

Title: Improvements relating to trimming mechanisms for grinding wheels
IPC: B24B53/08
Filed: 1941-02-22
Abstract: 542,917. Trueing grinding-wheels. GEAR GRINDING CO., Ltd., and BULLOWS, R. J. Feb. 22, 1941, No. 2427. [Class 60] A wheel a, Fig. 6, for grinding gear wheels, screw threads, spline shafts &c. is trimmed by a diamond g, Fig. 1, carried at one end of a shaft f, the other end r of which co-operates with a templet q, the shaft being supported so that it can oscillate about its axis and in two planes at right angles to each other, moved by driving and driven cranks t, s connected by a rod x, and controlled so that the diamond traverses the desired path determined in part by the templet. The movement of the upper end of the rod x is controlled by a spring z and by slotted links 8 connected to slides 5 pressed outwardly against stops 7, Fig. 2, by a spring 2. The part e of the shaft f is offset so that the diamond is spaced from the shaft axis by a distance equal to the radius of the curve a of the rounded edge d, Fig. 6. The shaft is mounted in a sleeve h universally jointed at j, k, m to the frame n. When the device is in the position shown the diamond is in the centre of the face c of the wheel a and on rotating a worm v by hand or automatically the crank t moves the rod x so that the shaft f swings about the bearing m and the diamond moves towards the edge d until the roller r engages one of two templets q. Continued movement of the crank t causes the shaft to rotate about its axis and the diamond to traverse the curve d until arrested by one of two stops 10 carried by a floating bearing 9 which is prevented from rotating by a yoke 12, to which the spring z is connected, and a lever 14, hinged at 15 to the frame n. Then the roller r traverses the templet and the diamond the curve b until the crank t is arrested by a stop 17. The movement of the crank is then reversed and continued so that the diamond traverses the other corner d and curve b. The sleeve h may be pressed up by a spring p and this movement be limited by a stop 16 which engages the lever 14. The-frame n may be arranged on a slide to be movable to and from the wheel a.

Filed: 1956-01-27
Abstract: 824,655. Heating buildings. BROSENIUS, K. H. Jan. 27, 1956 [Jan. 27, 1955], No. 2734/56. Classes 64(1) and 64(2) [Also in Group XXIX] A central heating plant for a building comprises a boiler 4, Fig. 1, a heat consuming apparatus such as a radiator 13, a heat accumulator 1 containing a water magazine, a pump 16 and thermostatic means 18 actuated by room temperature to control the pump. Two three-way valves 14, 15 enable the radiator 13 to be directly connected to the boiler through pipes 22, 24 while a valve 9 may be open or closed according to whether or not surplus heat is available for the accumulator 1. If firing ceases, the valves 14, 15 (see Group XXIX) are automatically changed over by thermally-responsive devices once the main part of the heat in the boiler has been utilized so that the radiator 13 is fed exclusively by the accumulator 1. To avoid corrosion, the boiler may be flushed with hot water from the top of the accumulator 1 before re-firing. For this purpose, the valve 9 is opened, a valve 26 in a pipeline (10) is closed and the valve 15 is turned to connect pipelines 12 and 24 with each other, the pipeline 23 being disconnected. To prevent self-circulation when the pump is stopped the pipe 24 may be connected to the top of the boiler while the pipe 22 is connected to the bottom and fitted with a one-way valve. Alternatively, a valve which can only be opened by pump pressure may be used. The pipe 12 may be connected to the pipe 10 so that the valve 15 and pipe 23 become unnecessary and the valve 14 is used to connect the radiator 13 to both the boiler and the accumulator or to the latter alone. Appropriate dimensioning of the pipes and the presence of dense cold water in the pipe 8 prevents return flow through the boiler when the. radiator is being fed by the accumulator 1. For further simplification, both valves 14, 15 and the pipes 22, 24 may be dispensed with. A small radiator may be connected to the boiler to utilize the heat remaining, in the latter after the accumulator has been charged.
