Abstract: A cross-country ski binding for cross-country ski shoes which have, at their front sole end, engagement elements which correspond with and engage into engagement elements of the ski binding, to provide a pivot connection. The ski binding has a U-shaped clip or stirrup member for securing the front sole end against lifting off the ski binding engagement elements, the legs of which clip are mounted pivotably about a transverse axis by their free ends to side jaws of the ski binding, which are fixed to the ski, and which clip is loaded by a spring in the direction toward a position engaging over the front sole end by its web portion. Further, the ski binding has a spring-loaded locking lever, which can engage behind a catch projection of the ski binding by means of a latch and can thereby hold the U-shaped clip in an open position. In this open position of the clip a cam element is provided in the path of movement of the front sole end when it is inserted into the ski binding, which cam element can be actuated by the sole end so as to lift out the latch of the locking lever and to cause the clip to engage over the front sole end.

Abstract: A camera for producing 3-D motion pictures has "left eye" and "right eye" camera lenses and two corresponding film transport mechanisms. Images to be recorded on films transported by the mechanisms are reflected by semi-transparent mirrors and the mechanisms are arranged so that the mirrors turn the images transversely of the films.      Contact prints made from the films can then simply be turned face-for-face to correct for the image reversals due to the presence of the mirrors. The contact prints are then correctly oriented for projection.

Abstract: A image detector includes an array of photodetectors arranged in n rows and m columns with at least a portion of the photodetectors in each column being selectively connected to a common column output signal line by a selector means. The image information is read out of the photodetectors by sequentially selecting groups of rows starting with a row near the middle of the array and then sequentially selecting other groups of rows on alternate sides of the array middle. As image data is read out of the photodetectors in the selected row group, groups of column output lines are coupled together to provide a combined output signal. This readout technique provides a reduction in the image data and reduces the likelihood of signal degradation for the central portion of the image.

Abstract: A compact disc-like display device is adapted to display a sequence of pictures which jointly represent a full-motion video scene, which picture sequence is digitized by means of some suitably chosen encoding algorithm. The digitized picture sequence comprises a series of video blocks. Since the disc continues to rotate at the normal speed when the picture sequence is displayed in slow motion, or in the case of a freeze, discontinuities in the display of the picture sequence are produced. To inhibit this, a header referring to a predetermined video block, preferably the next block, is associated with each video block so that the display device has information about that picture which is to be displayed next. The display device searches, reads and processes the associated video block on the disc.
