Title: Double hinged door for container - has panels linked by two push rods and common slider bearing
Inventor: ZIMMERMANN WILHELM
IPC: B65D90/00
Filed: 1975-10-08
Abstract: The container door consists of two panels (5, 6) which are hinged along parallel container edges (7, 8). A crank block (17) near the hinge on the inside of each panel, provides a hinge location for two push rods (3). The opposite ends of the push rods are linked to a central slider bearing (12) which is located by a guide bar (10). Since the two door panels (5, 6) are connected by rigid linkage, they are forced to move in synchronized angular motion. As the two panels (5, 6) are always balanced due to the push rod linkage, the operating force required for opening or closing the door, is a minimum.

Title: Flat filament winding process - uses two prodn. steps in which carrier bends wire in U shape about lug
Inventor: DOHLEN KLAUS V
IPC: H01K3/02
Filed: 1976-01-27
Abstract: The process for winding a flat filament includes bending of the tungsten wire (1) in two subsequent steps, using a rotary carrier (4).
