Patent FR-2318291-A1 (FR)
Title: Roll up curtain intermediate retaining and guide support - with additional top continuous strip assisting in holding curtain roller
IPC: E04F10/06
Filed: 1975-07-17
Abstract: The roll-up curtains have a considerable open length between the end attachments, so that an intermediate support is needed, for prevention of excessive sagging. The intermediate support serves for retention and guidance of the roller, which rests on a continuous roller-borne strip. The support incorporates an additional continuous strip at the top, pressing on the curtain roller, so that this is held between the two lengths of strip. The strips may be made of elastic material, and be stretched so that they form a virtually flat surface if the curtain roller is absent from the place where they should grip it. They may have transverse ribs on the outside facing the curtain roller. This prevents permanent folding, creasing and eventual premature wear or tearing of the curtain material.

Title: Stabilised hull for hydrofoil boat - with enclosed elliptical shape forming capsule allowing shorter foil spacing
IPC: B63B1/04
Filed: 1975-07-31
Abstract: The hull of the hydrofoil boat has an elliptical shape with a width to length ratio of about 1:2. the sides of the hull slope upwards and inwards to form an enclosed capsule. The hull has a main support member comprising a horizontal ring on which the sides are built. The floor is strengthened by a number of parallel struts supporting the floor above the bottom of the hull. The fore and aft hydroplanes are in a wedge shaped array and are spaced closer together than in a conventional boat. This provides a more stable system with the boat less affected by waves. If the boat drops into the water, the capsule shape helps it bounce back onto the hydroplanes again.

Title: Vertically moving car door window - with convex shape matching body contours guided on curved rails
IPC: B60J1/17
Filed: 1976-03-04
Abstract: The vertically moving window (8) in the car door is curved in two directions for optimum wind drag and noise reduction. The lateral curvature has a set of arcs whose centres of curvature lie on the same horizontal line, but with different radii. The window bulges to follow the shape of the car. The door is fitted with curved guides, curved the other way so that the window pane is guided in an arc. The design enables doubly curved panes to be used, so that the body contour is smooth. This reduces drag as well as noise.
