Abstract: 363,840. Discharge apparatus. VATEA RADIOTECHNISCHE & ELEKTRIZITATS AKT.-GES., 7, Csaba Ucca, Budapest. Dec. 30, 1930, No. 39162. Convention date, March 4. Drawings to Specification. [Class 39 (i).] In the manufacture of photo-electric cells and other vacuum discharge tubes, metallic ions, particularly those of the alkali and alkaline-earth metals, are introduced into the wall of a glass vessel by partially filling the vessel with a salt of the metal, e.g. potassium nitrate, immersing it in a suitable fused bath and passing a current through the glass from an internal anode. By subsequently exhausting the vessel and immersing it in a fused bath, e.g. of sodium nitrate and passing a current through the glass in the contrary direction to an internal incandescent cathode, the metal is introduced into the interior of the vessel where it may be condensed to a layer by air-jets. The vessel may be of soda glass. Successive layers of different metals may be introduced into the glass by the preliminary electrolysis and introduced into the interior of the vessel by the subsequent electrolysis. They may then be alloyed by fusion. In the case of refractory metals, the various layers should be of atomic dimensions ; an alloy can then be obtained without fusion. The several metals may be introduced into different parts of the vessel of varying areas, e.g. a large.layer of potassium and a smaller layer of caesium.

Abstract: 1,261,388. Method and machine for deforming circular tubes. I.C.E.A.-S.A.S. IMBALLAGGI CARTOTECNICA E AFFINI. 7 Aug., 1969 [23 Aug., 1968], No. 39560/67. Heading B5A. [Also in Division F2] A method of forming tube portions of rectangular cross-section comprises hot deformation of a circular cross-section tube made wholly or partly of thermoplastics material. In order to obtain plane faces on the finished tube the sides are bowed inwards during the forming process and cool to flat surfaces. In a machine for performing the method a turntable 7 supports a number of forming stations G around its periphery (Fig. 11). Each station comprises vertically opposed carriages 101 joined by springs M and supporting radially extending jaws 1 (Fig. 9) which may be forced apart by outward movement of wedge 26 between the carriages. An outer mould 2 corresponds to each jaw 1, and these are adjustable by means of screws 114 in bushes 13. A pair of horizontally opposed jaws 3 are mounted on shafts 15, which shafts form part of a parallel linkage (Fig. 10) actuated by motion of plate 29. Wedge 26 is supported on shaft 25 passing through bush 27 on plate 29, the shaft and bush being connected by levers 23, 24 pivotally joined at 123 constrained to move in the horizontal slot 121 on shaft 21 (Fig. 11). A spring 33 resists movement of plate 29 axially along shaft 25. Operation.-A portion of circular tube T1 is fed over jaws 1 and between jaws 3. Raising of piston 130 pushes shaft 21 upwards and forces shaft 25 and plate 29 in opposite directions, the latter remaining stationary due to spring 33, and the former operating jaws 1 to expand the tube T1 vertically into moulds 2. When pivot 123 reaches the leftward end of slot 121, further movement of shaft 21 causes rightward movement of plate 29, and hence closure of jaws 3 to compress the vertical sides of tube T1. When pivot 123 is above the position of maximum displacement of shaft 25 with respect to plate 29, it abuts stop 28 and is held there due to the action of spring 33. Piston 130 is withdrawn and the table 7 is rotated to bring the next station G into register with the loading device. When a station G approaches a discharge station, flange 221 engages slot 231 of a piston 131 and is withdrawn downwards, reversing the above procedure and leaving the tube T1 free to be displaced from the machine at the next station.  The jaws 1, 3 and moulds 2 are heated (e.g. by electrical resistance heaters).
