Title: Improvements in or relating to photo-electric cells
IPC: H01L31/06
Filed: 1960-08-26
Abstract: 898,204. Photo-sensitive devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 26, 1960 [Aug. 29, 1959], No. 29546/60. Drawings to Specification. Class 37. A photo-electric cell capable of detecting, and measuring the intensity of, radiation in both short- and long-wave regions of the visible spectrum comprises a semi-conductor body having a P-N junction, the photo-sensitive part of the body being of GaP. This part of the body may comprise lattice distortions, which may be produced by the presence of Zn and/or of an excess quantity of Ga. As described, a solution of P in Ga is obtained by heating the two substances in a 2-legged quartz tube, the Ga being heated at about 1220‹ C. and the P at about 430‹ C. The solution, which contains excess of Ga, is cooled to produce GaP crystals comprising a P-N junction together with a Ga phase which can be removed with dilute HCl. One side of the crystals is coated with Ag and a photosensitive position is located on the opposite side by means of a Mo pin. Such crystals exhibit maximum sensitivity to radiation of about 5600 Š and about 4200 A. Similarly produced GaP crystals in which a quantity of Zn is added to the Ga before heating (the Ga-Zn being heated in this case to about 450‹ C.) exhibit a high sensitivity at about 6000 Š. The P-N junctions may alternatively be formed by doping GaP crystals with impurities such as excess P or Ga, or S. Photo-cells according to the invention may be used as photo-voltaic or photo-conductive devices, or as photo-transistors. Reference has been directed by the Comptroller to Specification 719,873.

Title: Method of reducing overheating in melting troughs and similar devices in electrically heated melting and holding furnaces
IPC: H05B6/20
Filed: 1962-08-01
Abstract: 967,984. Stirring molten metal. E. A. OLSSON. Aug. 1, 1962 [Aug. 3, 1961], No. 29588/62. Heading F4B. Overheating in the melting troughs or heating channels of electric metal melting or holding furnaces is prevented by blowing gas into the melt near or in the trough or channel so as to promote the circulation of the melt. In a submerged resistor induction furnace, Fig. 2, the sides of the melting trough 3 are independently connected to the furnace space proper by slots 9 formed in the furnace lining. The secondary circuit is completed by a metallic bar 11 extending through the lining between the slots 9. Air or gas is blown into one slot 9 so as to increase the flow out of and into the trough 3 from the main body of the melt. Gas may be fed asymmetrically to the throat of a melting trough open to the furnace space over the greater part of its width. In a furnace heated by the passage of current between electrodes 23, 24, Fig. 3, over-heating in the channel 22 is prevented by supplying gas to the channel by a nozzle 25. The gas supplied may be a refining gas, and alternative supplies may be provided so that cheap gas may be used during holding periods to replace an expensive refining gas.
