Title: Roller type fabric sun blind - has sections of fabric joined along transverse lines parallel to roller
IPC: E04F10/06
Filed: 1973-06-12
Abstract: The sun blind of the invention is a roller blind which may be opened horizontally, vertically or at an oblique angle.

Title: Screwdriver handle with varying cross section - has triangular cross sections which are rotated relative to each other
IPC: B25G1/10
Filed: 1975-07-17
Abstract: The tool handle, especially for a screwdriver has a variable cross section which becomes narrower towards the tool and then flares out.
