Inventor: BAUMANN WILLI
IPC: E06B9/388
Filed: 1980-03-08
Abstract: The gatherable lamellar blind has two lamella-support cables (1, 2). The end rail (4) is connected to the lamella (6). Both are guided in lateral guide grooves (9). The flanged edges (11, 12) are connected to the wire cables (1, 2). In the central part, the lamella (6) is provided with a lamella hinge clamp. Two tabs (20) serve to receive a hinge connection element (21). Two pivot bearing projections projecting on the element (21) engage in the opening of the tabs (20). A cross-sectionally hook-shaped end rail holder (22) holds the element (21) securely. As a result, a connection which is pivotable about two axes (24, 25) is produced between the lamella (6) and the end rail (4). In the closed state of the gatherable lamellar blind, the lamella (6) bears with its rubber piping (29) as extensively as possible against an end rail stop (27). By pulling upwards on the lamella support cable (1), a closing moment is created on the lowest lamella (6), which is not hindered by the hinge connection element (21). The lamella (6) can thus be drawn into a real closing position. It is not possible from outside, by pressure on the upper part of the lowest lamella (6), to cause the latter to pivot out. As a result, a complicated construction and the openability of the lowest lamella (6) from the outside are avoided. <IMAGE>

Title: TV camera coping with moving objects - limits charge integration to certain partial time region of scanning interval
Inventor: HEINLE GEORG DIPL ING
IPC: H04N5/30
Filed: 1980-04-19
Abstract: The appts. is used in laboratory investigations of fast moving objects. In order to obtain well defined images the charging time of the individual capacitors forming the signal plate (3) is restricted to a fraction of the line scan and reset time for the plate. The relationship between these times has to be precisely defined. With the proposed timing alteration standard cameras and video receiving apparatus can be used. Typically either the illumination time of the photo-cathode (2) or the illumination time of the object to be recorded is limited to the desired integrating time interval for the signal plate (3) capacitors. The timing may be achieved by a shutter (5), flash illumination of the object, or electronically from inside the camera. Whichever method is used it must be synchronised to the line scanner. Either conventional or CCD cameras can be employed.
