Title: Folded window blinds mfr. - using cavity forming webs of different fusion temp. material to prevent through welds
Inventor: KOESTER HELMUT DIPL ING
IPC: E06B9/24
Filed: 1979-09-12
Abstract: The Parent Patent described a method of joining the web areas with the size walls of folding window blinds by a welding process. The welded seams or spots are prevented from passing through the entire laminate by using for the webs two layers of materials with different fusion temperature. The web material is unwound from a reel, cut in strips and brought together with one side wall foil of radiation permeable material; with a higher fusion temperature (polycarbonate) which is welded first to the webs of the same material. In the next stage, a side wall foil of a lower fusion temperature (polypropylene) is welded to the web of the same material. This saves special release layers to prevent through welds.

Title: Chopper driven inverter with regulator - has output transformer designed to limit interaction between windings due to load change on one winding
Inventor: STUEDEMANN BERND ING GRAD
IPC: H02M3/335
Filed: 1979-09-27
Abstract: The chopper driven inverter is of the type employed in a television receiver to provide the power supply for the picture tube and the audio amplifiers. The transformer has an input winding (P) which is connected to a dc source and in which the current is interrupted periodically by a transistor switch (T1). One secondary winding (S1) provides power for the chopper control and regulation. The other secondary windings (S2,S3,S4) give the power supply output to various load circuits. The secondary windings of the transformer are arranged and dimensioned such that the effect of a sudden load variation in one winding causes minimum voltage disturbance on the other windings. Typically the regulating winding (S1) is closely coupled magnetically with the other output windings so that voltage variations act directly on the regulating circuit to produce rapid corrections.
