Patent EP-0054170-A3 (EP)
Title: Method of correcting the positional error of a rotating polygon mirror
IPC: G02B27/00
Filed: 1981-10-30
Abstract: Positional errors are corrected for a light beam which is deflected point and line-wise across a scanning surface by a polyhedral rotating mirror. For each mirror surface, the positional errors are measured in the line direction and perpendicular thereto at a plurality of measuring points oriented in the line direction in the area of the scanning surface. Correction values are generated which, during simultaneous error measurement, are changed until the positional errors are compensated by means of correction elements. The determined correction values are stored and are read out for continuous correction during the actual operation synchronously with the mirror surfaces simultaneously located in the beam path. Light deflectors are employed as correction elements. Employing the rotating mirror in a recording arrangement, transit time elements controlled by the correction values are disposed as correction elements in the signal path of the image signal for the correction of the positional errors in the line direction. If the image signal is stored, the frequency of the read clock can alternately be changed as a function of the correction values. The method is very accurate so that, in particular, errors caused by uneven mirror surfaces are corrected.

Patent EP-0111852-A3 (EP)
IPC: B65D88/16
Filed: 1983-12-09
Abstract: The present invention relates to a flexible container for 
transport and storage of bulk material and a method for its 
manufacture. The container shall endure the strains it is 
exposed to during a drop test in the bursting zone having a 
radial bursting effect. The container (1) consists of a 
hose-formed piece of material which upper part is joined 
with its central part (12) by joints (8) which form an angle 
0°<x<90°, preferably 30°<x<60° with the longitudinal direc­
tion of the material. The joints (8) can be in the form of a V or 
W and the extreme point (B) if preferably above the bursting 
zone (9). The container (1) can be made from a flattened 
hose-formed piece of material which is cut in two symmetric­
al parts (1) along a line cut a, a′, b′, b where the lines a, a′ and 
b′, b form an angle 0°<x<90° with the longitudinal axis of the 
material and the line (a′-b′) ≧ 0 is vertical in the middle of 
the piece of material (1) on both sides of the folded line (1). 
The upper part of the piece of material (1) is folded over the 
line (2) and joined with the part (12) along cut lines for 
forming lifting loops (5). The container combines the require­
ments to high tensile strength and high resistance to strain in 
the bursting zone (9).

Title: Information display system
IPC: G06F3/037
Filed: 1983-08-01
Abstract: An information display system which can produce an information display (e.g. on a television monitor) from any one of a plurality of different information sources. The information sources are associated with different facilities such as teletext and viewdata. For obtaining information from a particular information source the associated facility option is selected. This selection is made from the available facility options by selecting from the television screen "nested" areas which pertain to one or more facility options. The selection can be effected using a touch-sensitive screen which overlies the television screen. The selection process can involve the display of a number of successive display frames containing "nested" areas, the selection of an area in one frame causing the display of a fresh display frame which re-defines areas which are nested within the selected area.

One of the surfaces (25, 61), being flexible, is connected to the shaft (8) so as to flex in response to torque between the reference point (24, 59) and the test point (29, 68), causing a change in the angle between the lines on the two surfaces (20, 25; 60, 61), and thus of the spacing (D) (Figure 3) of the moire fringe bands (30), which is optically detected (17) and converted, as shown in Figure 4, to an electrical signal (42) to control power applied to the shaft (8).
