Patent GB-483333-A (GB)
Title: Process for the manufacture of manganese pigments
IPC: C09C1/00
Filed: 1936-10-20
Abstract: Manganese pigments are manufactured by precipitation from a 5-30 per cent solution of a manganous salt by means of a 7-18 per cent suspension of alkaline earth, e.g. calcium, hydroxide such that from 1,2 to 3 molecules of hydroxide per atom of manganese are employed, with simultaneous oxidation by air and final calcination.  The brown precipitate is washed substantially free from calcium chloride, and then calcined.  At temperatures between 680 and 950 DEG  C. the pigment progressively darkens from a yellowish green through dark green to black.  The pigment may be improved by incorporating inorganic or organic salts, e.g. sodium chloride or sodium oxalate, in the precipitate before calcination. The Provisional Specification states that the brown precipitate may be used as a pigment without calcination.

Abstract: 708,628. Starting prime movers. DAIMLER-BENZ. AKT.-GES. Nov. 23, 1950 [Aug. 3, 1950], No. 28727/50. Class 38(4) [Also in Group XXVII] For a fuel-injection engine particularly for a motor vehicle a common operating member is provided which is adapted in one position for stopping the engine and in another position for causing actuation of the starter and simultaneously setting the fuel supply to the engine to a value higher than the normal full load value appropriate for starting. Normal regulation of the fuel supply may be effected by the operator or automatically. As shown, the regulating element 1 of a fuel pump 2 supplying a vehicle diesel engine, for example; is moved in normal operation by a diaphragm 3 acted on by the suction in the induction pipe on the engine side of a throttle valve. Stops 5, 6 are provided on the regulating element which co-operates with a lever 7. The lever 7 is coupled to a control lever 9 which is further coupled to a lever 11. The lever 11 may be on the shaft 10 or as shown on a parallel shaft. The lever 9 has four positions indicated on the drawing by the marks " Stop," "Norm.," "Prepn" " and " Start." In the normal position of the lever 9 the end of the lever 7 is so positioned that the element 1 can control the fuel supply without contacting the stops. When however the lever 9 is moved into the starting position the element 1 is moved by the end of the lever 7 contacting the stop 5 to adjust the fuel supply to a value suitable for starting higher than the normal full load value. At the same time the lever 11 which is formed as a switch makes a circuit 13 for an electrical starter motor. In the preparation position of the lever a circuit 12 for incandescent starting plugs is completed. In the stop position the end of the lever 7 co-operates with the stop 6 to cut off the supply of fuel. The starting plugs may be wholly or partially energized during actuation of the starter. The regulating element 1 may comprise a rack which turns the pump pistons.
