Abstract: 1314951 Growing mixed crystals PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 May 1971 [30 May 1970 1 July 1970] 17361/71 Heading B1S [Also in Division C1] In the manufacture of a mixed crystal by cooling a quantity of liquid which contains the components of the crystal, the position of the crystallization front between the crystal and liquid phases is adjusted within a temperature range such that its temperature is substantially the solidus temperature of the desirable composition of the mixed crystal in the phase diagram of the components thereof. The invention is described in relation to lead telluride and tin telluride mixtures forming a mixed crystal of formula Pb 1-x Sn x  Te. Apparatus for performing this method consists of a furnace having three heating elements 4, 5 and 6, a drawing device 1 and a rotating device 2. The element 4 is mounted freely relative to the inside of the furnace. Two oppositely located windows 9 are provided for observing the growth, a quartz tube 11 closed at either end containing the growth vessel 12 in the interior of the furnace, this being rotated by the driving mechanism 2. The growth vessel 12 is a quartz tube closed at each end within which the components of the mixed crystal to be produced are sealed in vacuum (after previously being melted in a vacuum to produce a polycrystalline rod and remove enclosed gas). The position in the furnace at which the temperature is that required for the required composition (the solidus temperature therefor) is found by a thermocouple, and marked and a point at the top of the vessel 12 (as shown) placed at a point just below the solidus temperature, the lower part (which contains the mixture) being above this so that it melts and a vapour forms which condenses in the point of the vessel 12 and then crystallizes. After the crystallisation front has moved down to the point at which the solidus temperature exists the vessel is moved up to keep it there.

Abstract: 697,822. Diaphragm pumps. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM NAATSCHAPPIJ. July 23, 1951 [July 21, 1950], No. 17405/51. Class 102 (i) [Also in Group XXIX] A pump, particularly suitable for muddy liquids, comprises a pair of chambers, 1, 1<SP>1</SP>, divided by diaphragms 2, 2', the lower chambers of which form the pumping chambers and are connected to suction and delivery valves 6, 6', 8, 8'. The upper chambers are alternately supplied with operating liquid or connected to suction for withdrawing the liquid under the control of the change-over valve 15, and it is arranged that the suction stroke is performed more quickly than the forcing stroke, e.g., by arranging that the forcing pump 13 has a smaller capacity than the suction pump 12. The change-over valve is arranged that during the operation of changing the connections to the diaphragm chambers, the rate of increase in area of one set of passages is equal to the rate of decrease in area of the other set so that the combined delivery of the two diaphragms remains constant. The change-over valve is actuated by a piston 22, the supply and exhaust of pressure fluid to which is controlled by a slide valve 34 for each diaphragm and actuated by stops 38, 39 on a rod 37 connected to the diaphragm. The arrangement is such that the diaphragm that executes its suction stroke adjusts the appropriate valve 34, but the piston 22 is not operated until the other valve 34 is adjusted by the diaphragm reaching the end of its forcing stroke. The diaphragms may carry valves that close the liquid passages when the diaphragms are at the ends of their strokes. Indicators 45, 45' may be provided that respond to electrical conductivity or di-electric constant of the liquid passing in pipes 18, 18' to detect leakage of the muddy liquid pumped into the operating liquid. The pumps may be supplied with muddy liquid under pressure.
