Abstract

313,602. Petrik, J. June 15, 1928, [Convention date]. Theri22o - electric batteries.-The electrodes of a thermo-electric battery are enclosed in an exhausted and hermetically sealed metal box. A number of boxes are mounted parallel to one another with spaces between them for the reception of hot liquids or gases and also the cooling medium. The ele:etrodes may consist of solid metal rods or blocks or of compressed powder arranged within supporting shells. Fig. 3 shows a number of electrodes 1 placed between and abutting against copper plates 2, 3 connected by bridge pieces 4. The complete unit is placed in a nickel steel box 6 lined with asbestos paper and closed by a cover 8 welded in position. Silvered mica strips 5 may be mounted as shown in Fig. 4 to form reflecting surfaces. The box is exhausted through a side opening. The electrodes 1 may be of various shapes, and if of insufficient rigidity they may be stiffened by internal or external quartz or glass elements 13 as shown in Fig. 1. Fig. 7 shows an electrode made from a powdered material 1 contained in a quartz or glass tube 14 fitted with a metal bottom 15 and a stopper 16. Powdered materials may also be subjected to hydraulic pressure to form electrodes in the form of plates which may be provided with metal plated surfaces. Fig. 10 shows a complete battery comprising a number of boxes 6 as shown in Fig. 4 arranged parallel to one another in an outer casing. Hot liquids or gases are led through the passages 21 between the boxes, and a cooling medium through the passages 22.
