Title: Cold extrusion process helical workpieces - uses superimposed relative rotary movement of piston
Inventor: WEZEL ERICH
IPC: B21J13/03
Filed: 1979-03-07

Title: Automatic detection and sorting of polarisation elements - by evaluating uniformity of multiple section photoelectric transducer output signals using transverse polarisation
Inventor: LANZ OTTO
IPC: B07C5/34
Filed: 1979-05-25
Abstract: The device for automatic detection and sorting out of faulty polarisation elements is applicable to liquid crystal displays. The elements pass through a test station on a carrier tape. They are illuminated in the station where faulty elements are rewired and carried away along a separate path. An optical system forms an image of the element in the station on a multiple section photoelectric transducer. An electronic circuit produces an error signal if the output signals from the transducer are not equal. The focal length of the optical system is variable to accommodate polarisation elements of different sizes. The system evaluates markings on the elements whose contrast w.r.t. the elements is enhanced by a polariser with polarisation direction perpendicular to that of the elements.

Title: Purifier for tobacco smoke - circulates room air through filter and convector fan
Inventor: WENGEL JUERGEN
IPC: F24F8/108
Filed: 1980-02-07
Abstract: A system for the purificn. of the air in rooms, which is contaminated by tobacco smoke uses a conventional convector fan which pulls the smoke through a chemical, mechanical or electrostatic filer. The emerging air is returned clean to the room.
