Title: Improved beaming apparatus on warpers
IPC: D02H3/00
Filed: 1951-09-07
Abstract: 700,135. Beaming yarns. MASCHINENFABRIK BENNINGER AKT.-GES. Sept. 7, 1951 [Sept. 18, 1950], No. 21185/51: Class 142(4) In a beaming apparatus cross-winding is effected by oscillating a worm wheel engaged with a guide spindle to reciprocate a beaming carriage, the guide spindle being rotated from the machine drive to traverse the carriage. Boxes 5, 6 connected by a tube 8 form a carriage holding a warp beam 7. The beam is driven by a chain drive 15 from a shaft 13 rotated from the machine drive. The chain drive 15 also drives a wheel 17 which rotates, through suitable gearing, an eccentric 27 on which a lever 30 engaging a sleeve on a shaft 20 is mounted. The sleeve is clutched to the shaft 20 which carries a worm wheel 21 engaging a guide spindle 12. Spindle 12 is rotated by the machine drive, and the worm wheel, being prevented from rotating by the engaged clutch and lever 30 acts like a nut on the spindle and gives a continuously longitudinal displacement to the carriage. The rotaticn of the eccentric 27 activates lever 30 and oscillating worm wheel 21, which rolls on the spindle 12. A reciprocating motion is thus superimposed on the longitudinal displacement communicated to the carriage 5, 6, 8, which is mounted to run on rails. The position of the box 5 on tube 8 may be varied, and the carriage may be positioned for beaming by disengaging the clutch and rotating a handwheel.

Title: Improvements in or relating to processes for the production of alloy single crystals and semi-conductor arrangements produced by such processes
IPC: H01L21/00
Filed: 1956-07-13
Abstract: In a process for the production of semiconductor single crystals of an alloy having a predetermined composition, the components of the alloy are deposited from the gas or vapour phase on the surface of a seed crystal of one component, and the ratio of the components deposited is gradually changed from an initial composition consisting almost exclusively of the same component as the seed crystal to the predetermined composition.  The seed crystal may be silicon on which silicon with a small amount of germanium is deposited from a gas mixture, the proportion of germanium being increased as the deposition progresses, until the desired composition is reached; the proportion of silicon deposited may then be reduced until a zone of the crystal consisting only of germanium is obtained.  The gas mixture may consist of silicon chloride and germanium chloride, the proportions being varied as required, the silicon and germanium being obtained by thermal decomposition and/or reduction with hydrogen. Donor and acceptor material may be added to the gas mixture for inclusion in the growing crystals to obtain zones of different type or degree of conductivity.  Acceptor material may be added to the first part of the crystal to obtain a strong p-conductivity zone, followed by donor material and then by acceptor material to obtain a P-N-P-junction, the strongly-conductive zone serving as an emitter. Crystals may be grown having a middle zone of a material or alloy of desired band-width, diffusion length and carrier mobility, as a base with adjacent layers of different materials or alloys as emitters or collectors or intermediate layers such as hook or intrinsic zones.
