Abstract: Device for crucible-free zone melting a crystalline rod substantially vertically supported at the ends thereof in a zone melting chamber includes heating means extending into the chamber through a substantially vertical slot formed in a side wall of the chamber. Slide means located adjacent the side wall carries the heating means and is slidable therewith relative to the rod axis. Elastically deformable sealing means are mounted between the sliding surface of the slide means and the side wall and completely surround the slot so as to seal it gas-tightly. The slide means, at least at the sliding surface thereof, are formed of a material of good slidability, the sealing means are formed of a material effecting a dry seal with the sliding surfaces, the paired materials having a frictional coefficient of at most 0.2.

Abstract: 907,569. Photo-electric devices. SIEMENSSCHUCKERTWERKE A.G. Feb. 20, 1959 [Feb. 22, 1958], No. 5975/59. Class 37. In a photo-cell comprising a semi-conductor body with at least one PN junction, part of the surface of the body forms part of the outer surface of a sealed housing enclosing the regions where the PN junctions come to the surface of the body. An NPN type photo-transistor (Fig. 1) is made by allowing foils of gold-antimony alloy to opposed surfaces of a P-type silicon wafer. The central part of one of the alloyed foils is then removed to leave a recrystallized N-type surface layer with an annular alloy electrode 3. Alternatively the whole of the foil is removed and an annular electrode 3 provided. The electrodes 3, 4 of the resulting device are soldered or alloyed to areas of molybdenum or tungsten members 5, 9, plated with gold-antimony alloy. The housing is completed by a metallized ceramic cylinder 6 soldered between member 5 and a resilient copper diaphragm 7 formed integral with a mounting bolt 10, and a cooling block 8 on which member 9 is mounted. In another embodiment (Fig. 2) sensitive to local variations in light intensity within its exposed surface there are three collector-electrodes 13 which may be connected into independent circuits by wires 14 sealed through glass beads in wall 7 of an all-metal casing.
