Patent DE-3728160-A1 (DE)
Title: Lead-acid battery
Inventor: MALOTKI HASSO VON DR
IPC: H01M50/463
Filed: 1987-08-24
Abstract: A separation design for a lead-acid battery provides for positive and negative electrode plates (1, 2) being separated by a microporous separator sheet which, because it is constructed as a corrugated separator (3) or as a bilaterally ribbed separator (4), leaves approximately equal free sulphuric-acid volumes (5) to both electrode polarities, and for additional fabric or nonwoven overlays (6) on the electrodes on the one hand to prevent paste particles from penetrating into the free spaces, but on the other hand to allow easy passage of the gas bubbles generated at the electrodes during charging. These bubbles rise in the duct-like free spaces and, owing to turbulence, ensure that no stratification of acid occurs during charging. Thanks to the acid density equilibration thus achieved and to the adequate acid supply at the plates, the cell voltage, which is measured as the end-of-charge voltage, remains constant over a long service life. <IMAGE>

Title: Method and plant for the production of a planar cathode for a flat picture tube
Inventor: BOCK JOSEF
IPC: H01J29/04
Filed: 1989-01-03
Abstract: Such a cathode is formed by a plurality of heating wires which are located in a plane, covered with an emitting mass, and resiliently suspended from a frame. Since the electron emission in the flat picture tube of necessity has to be very uniform and so that in all heating wires a very uniform current has to flow, the heating wires have to be coated very uniformly with emitting mass. When the heating wires are coated as complete mesh grids or mesh grilles, it is not possible in every case to achieve the very uniform electrical field distribution required for a very uniform coating. According to the invention the heating wires are individually coated with the emitting mass and fastened one after the other to a frame of the flat picture tube. The heating wires are coated with the emitting mass in a cataphoresis bath and after the coating individually fastened to the frame by laser welding. <IMAGE>
