Title: Cord-holder profile element for vertically slatted blinds
Inventor: SPOHR HORST DIPL ING
IPC: E06B9/36
Filed: 1988-07-29
Abstract: A device for transporting slat carriers, guided in a load-bearing rail, of a vertically slatted blind, having a securing means for the pull cord, comprises a cord-holder profile element (19) which is provided with wedge grooves (22, 23) which taper in the cord-pulling direction.

Title: Chuck for rotating cutting  tools with parallel shanks - has driving collar on cutting tool to relieve locating collet of cutting force
Inventor: REINAUER JOSEF
IPC: B23B31/30
Filed: 1989-04-25
Abstract: Rotating cutting tools such as end mills with parallel shanks held in a collet type chuck suffer a loss of positional accuracy under high cutting loads. This is avoided by separating the locating and torque transmission functions. The tool shank (8) is accurately located radially and axially by the spring collet (12) and abutment face (20). Fixed to the tool is a driving collar (30) having flats around its circumference which drive onto the suitably shaped aperture of clamping ring (24). The clamping ring transmits the cutting torque to the chuck body (28) by way of holes which loosely engage with three pins set axially in the chuck body. Another version of the chuck achieves greater accuracy by using a hydraulically actuated collet. USE/ADVANTAGE - Machining centres and similar automatic machine tools. Greater accuracy and higher machine utilisation.

Inventor: RIEMANN UWE DIPL ING
IPC: H04N11/00
Filed: 1990-03-22
Abstract: When transmitting television signals with a 4:3 picture format for reception on a standard receiver and additional information, which may consist of additional lateral picture portions produced in the transmitter, for a 16:9 picture format for reception on a receiver which decodes this picture format, the additional information in a PAL signal is modulated to the colour information present in the PAL signal in such a manner that spectral spaces of the colour information (U, V) are doubly occupied. Cross-talk from the recognizable picture content (ghost image) is prevented by additional scrambling of the additional information. Parts (32, 33, 34) of the PAL decoder in the 16:9 receiver can be used advantageously at the same time to demodulate the additional signals.
