Patent DE-2518937-A1 (DE)
Title: Thermographic picture formation and reproduction - is by screen containing coarse and fine array of luminescent diodes responsive to different wave lengths
IPC: G01J5/00
Filed: 1975-04-29
Abstract: The procedure for producing and reproducing thermographic pictures uses a double screen with a coarse and a fine grid, the ratio of areas of square grid components being 16/1. The coarse and fine members are distributed over the screen in groups (1, 2, 3, 4) ... (11, 21, 31, 41) and comprise luminescent diodes with different colour responses. These respond to small temperature difference arising from a scene image on the screen, typically a landscape. The electronic circuit is formed by connecting groups of luminescent diodes in pairs to a series of operational amplifiers (5, 51, 6, 61, 7, 71), and series delay timing elements (8, 81, 9, 91). The equivalent temperature rise for a typical picture reception is calculated from an equation involving the geometry of the system, the intensity of light received per wave-length interval and the electrical and optical sensitivities.

Title: Self screening solid material for transformers - also has mechanical load bearing properties
Inventor: ANDERSSON OLLE
IPC: H01F27/32
Filed: 1975-05-12
Abstract: A material which may typically be used for screening and separating connections in electrical apparatus, for example oil filled transformers, combines the relatively void free properties of impregnated press phan with the mechanical properties of more solid materials. Typically it may be a glass fibre armoured synthetic resin bonded material, but the essential requirements are given by a formula which relates the conductivity of the solid material, the dielectric constant of the solid material, the dielectric constant of the surrounding medium (for example oil), the effective electrid field strength in the surrounding medium, the field strength in the solid material at which there is no discharge, and the operating frequency. The creep resistance of the material should be better than that of the presspahn, and the modules of elasticity is given. Temperatures over 115 deg. C can be withstood by the material.

Title: Multi:channel level detector for DC output signals - indicates which of several signals has highest instantaneous value
Inventor: LINDNER KURT DIPL ING
IPC: G01R29/10
Filed: 1976-02-20
Abstract: The multi-channel level detector indicates which one of n channels has the highest DC output level and is suitable for plotting and evaluation applications.
