Title: Improvements in apparatus for heating by electronic bombardments
IPC: H01J37/301
Filed: 1951-12-12
Abstract: 714,612. Cathode ray tubes. SUDDEUTSCHE LABORATORIEN GES. Dec. 12, 1951 [April 13, 1951], No. 29130/51. Class 39(1) [Also in Group XI] An electron beam 32 from ar electron emitter 15 in an evacuated casing 11 is focused tc impmge on small objects 75 ir recesses 66 in a slidable carrier rod 67, extending through sealing means 70, 73 in a wall of the casing 11, whereby the objects are brought in turn tc the focus position, where they are melted and on immediate cooling solidify into a spherical or rounded form. Thus small pieces of aluminium oxide of about 1 mm. diameter may be brought in turn under the beam by sliding the rod 67 in a tubular housing 53, and, aftei heating, the rod is rotated and the particles fall into a cooling oil bath 51. When the beam is focused on a larger object, only a desired part of it may be melted; but if the intensity of the beam is increased, the object may explode into small particles, which are melted, formed into spheres and collected in the vacuum chamber 11. The electron beam may be split by impinging on the head 123 of an earthed plate 122, and bent by deflecting electrodes 124, 125, 134-136 to impinge on opposite sides of an object 75. The deflecting electrodes are plates, or may be formed as short cylinders so that the electron beam is deflected as a continuous paraboloid envelope. Two separate electron streams from independent sources may be arranged to meet in a common chamber, so as to impinge on opposite sides of the object to be heated. The beam may be focused by an electronoptical system. The electrons may be energized at 50,000 volts or more. The cathode comprises a V shaped tungsten wire 15 heated by current passed through and having its tip projecting at the tip of an opening in a conical extension 21 of a cylindrical chamber 20 forming a control electrode connected to a wire 24 at a negative potential of 100- 300 volts as compared with the cathode 15, which is maintained at a potential of about -50,000 volts compared with earth. An integral cylindrical extension 23 of the control electrode may carry a number of sectors insulated and maintained at different voltages, corresponding to a number of part conical sectors 25 insulated within the cone section 21 of the control electrode. The sectors 25 have predetermined potentials applied thereto in order to render the beam circular in cross section and focus it at a distance of 10-30 cms. from the emitter. The anode 11<SP>1</SP> is earthed and has a central aperture 34 through which the beam passes. The electron beam may be operated intermittently or may be slowly decreased to allow cooling of the object 65 either by decreasing the applied voltage or by an adjustable apertured diaphragm 84; or the rod 67 may be heated to ensure slower cooling of the particles. Specification 714,613 is referred to.
