Title: Acrylic glass sheets opacified with barium - sulphate paste
Inventor: SCHMALZ HEINZ DIPL-CHEM DR
IPC: C08F20/14
Filed: 1969-11-04
Abstract: Pigment based mainly on BaSO4 is used in form of paste containing 3-6 wt.% hexaalkyl-, pref. hexamethyl-phosphoric acid triamide.

Title: Vibrations generator for casting concrete - utilises vibration coupling to synchronise two rotors
IPC: B28B1/087
Filed: 1973-12-07
Abstract: The two cut-off-balance rotors are mounted on a beam which pivots about an axis on a support. Vibration dampers are interposed between the beam and a base. When the rotors are rotated in opposite directions at approx. equal speeds and are in a certain posiiton, the horizontal forces cancel one another and the vertical forces tend to keep the beam in the horizontal position so that the system acts as a rigid body and transmits all the vertical forces to the structure. If the rotors are out of place a tipping moment is exerted on the beam and the vibration energy is absorbed by dampers.

Title: Light pen system selection - is of electrical pulse generated during passage of light signal of image through point on screen
Inventor: BRUEDERS ROLF DIPL ING
IPC: G06F3/038
Filed: 1974-01-26
Abstract: The screen is penetrated by the optical axis of a light-sensitive element which converts the light signals to electrical signals. A number of other electrical pulses are produced by the light signals from the lines Y +- j, which are adjacent to the line Y selected by the optical axis. In the pulse train produced during the line-by-line unblanking of the image, the timely distance between two successive pulses generating an output signal, is measured. A photodiode of high sensitivity is used for converting the light signals to pulse trains. A non-linear amplifier brings each signal to a predetermined voltage gain and is then converted to a light signal.

Title: Recording scanner for light reflecting mirror - uses reference beam for detecting spacial and temporal position of mirror surface
Inventor: BERGMANN UDO
IPC: G01D15/14
Filed: 1974-04-09
Abstract: The reference beam from e.g. a laser falls on a movable mirror which can turn about a point of rotation and is in an initial position. The beam is deflected to a light detector in a reference plane. This mirror can rotate and consists of several mirror faces. Furthermore the mirror can be attached to a galvanometer coil or to the membrane of a loudspeaker or to a piezoelectric material. By rotating the mirror to a new position, the reflected beam moves in the reference plane from light detector. As the information recording beam is reflected from the same mirror surface as the reference beam then a trigger impulse obtained from the two light detectors can be used to control the recording beam.
