Patent DE-3903082-A1 (DE)
Title: Securing cable
Inventor: MARSCHOLL KLAUS
IPC: B60R21/00
Filed: 1989-02-02
Abstract: A securing cable is described for connecting two components in a captive manner, which components are moved apart by an external force. The cable is wound in the thread grooves of an elastically deformable component which may, for example, take the form of a bolt with an external groove or even of a sleeve with an internal groove. A further rigid component limits the freedom of movement of the cable to the outside and/or to the inside, so that the cable can only be pulled off the elastic component in so far as the web remaining between the threads of the groove is successively pressed down by the cable. This results in absorption and/or elimination of the force driving the component apart, so that the components which are moving away from one another are not stopped abruptly, but are more or less gradually retarded.

Patent DE-3929967-A1 (DE)
Inventor: KEESEN HEINZ-WERNER DR
IPC: H04N7/01
Filed: 1989-09-08
Abstract: In a system for generating a compatible television signal with a "letterbox" display format, groups of vertically arranged picture elements (pels) are subjected to vertical DCT transformation producing eight DCT coefficients. Intermediate sixth and seventh coefficients are placed in the letterbox bar regions. The remaining six coefficients, namely the first through fifth coefficients and the highest frequency eighth coefficient, are inverse DCT transformed and processed with the main image information. A standard aspect ratio receiver displays a letterbox image using only the remaining six coefficients. A wide aspect ratio receiver uses the six remaining coefficients with the two coefficients from the bar regions, after inverse DCT, to produce a full resolution wide aspect ratio image.
