Abstract: 1,205,555. Speed frames. T. M. M. (RESEARCH) Ltd. 4 Dec., 1967 [6 Dec., 1966], No. 54577/66. Heading DID. In a speed frame the speed of the flyers and the front drafting rollers is reduced during the build to ensure that the surface speed of the bobbin and thus the tension in the roving caused by centrifugal force is kept to an acceptable level; the speed of the bobbin is reduced relative to that of the flyer to maintain correct winding on in the normal way. As shown, a constant speed motor 11 drives, through a variable speed gear 10, front drafting rollers 18, and flyers 24. The ratio of the variable speed gear is changed during the build by a link 12, 34, 33 associated with the belt shifter 33 of the builder mechanism. It can thus be arranged that the surface speed of the bobbin is maintained at a maximum throughout the build. The bobbins 47 are driven to maintain a fixed relation with the speed of the flyers in the normal way, their drive being compounded in a differential gear by the drive on shaft 13 and the drive on shaft 30; the output shaft of the usual charge speed device 27, 28, 29.

Abstract: 1367510 Zone-freezing of formed compound PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 Dec 1971 [11 Dec 1970] 57008/71 Heading B1S Single crystals of semi-conductor compounds are made in a combined reaction zone and zone-freezing sealed vessel by reacting a volatile component of the compound with a liquid component of the compound in proportions corresponding to the stoichiometric composition of the compound and during this reaction a seed crystal is positioned in a recess which is a continuation of a substantially horizontal oblong cavity containing the liquid component at such a height that the seed crystal cannot be reached by the liquid compound being formed until the end of the reaction after which a temperature gradient is moved away from the seed crystal parallel to the longitudinal surface of the liquid volume of the compound thereby forming the desired crystal. During the reaction an exposed vertical face of the seed crystal directed towards the liquid compound is maintained at a temperature which is below, but is substantially equal to the melting temperature of the compound, in a temperature gradient which extends on both sides of the face. The preferred compound is gallium arsenide. As shown tubular vessel 1 contained in a furnace 10 contains two boats 4 and 6 which contain respectively when heated the volatile component 3 and a liquid component 5. The two boats are separated by partition 9 which contains a small aperture for the passage of the volatile component. The boat 6 is extended to form a recess 7 which accommodates the seed crystal. The furnace contains a number of controlled heating zones as shown by the temperature spectrum T. In particular, the volatile component 3 has a temperature Ts which prevails in the entire zone B, the contents of boat 6 has a temperature TR which prevails in zone A, and is slightly higher than the melting temperature TF of the. compound and the seed crystal 8 lies in a zone C through which a temperature gradient passes. In zone C the exposed vertical face 28 of the seed crystal corresponds to point M of the curve and is at the melting temperature TF whilst the opposite end of the crystal corresponds to point N of temperature TP slightly below TF. At the end of the reaction the temperature gradient G is moved in the direction K whereby crysctallization of the compound takes place.
