Patent DE-2402838-A1 (DE)
Title: Low current constant power supply - has three transistor chip which ensures that resistance does not exceed 25 kilohms for low current output
Inventor: URBANSKI WILFRIED DIPL ING
IPC: G05F3/30
Filed: 1974-01-22
Abstract: The necessity to provide a constant current stabilised power supply has with prior art devices been achieved with two coupled transistors. When the current amplitude is very small, this has required coupling resistors of large values 100 kilohms to 1 megohm. The circuit has a transistor coupled to the consumer circuit and generating the load current. Two additional transistors are connected as diodes with resistors. In operation the use of the two transistors requires that the resistors are sized so as to satisfy the voltage difference between the two diode arrangements. In consequence even very low output currents require only small values of resistance, typically 10 to 15 kilohms.

Title: Optical arrangement for micro colour pictures - encompasses taking and projecting as well as three dimensional and copying
Inventor: YEVICK GEORGE J
IPC: G03C7/14
Filed: 1975-05-07
Abstract: Optical micro apparatus for taking or projecting micro colour pictures, consists of a transparent plate lens cage (Fiche) with a number of regularly spaced lenses on its surface and a photographic emulsion on its lower side. Colour filters red, green, blue, are each in line with on lens. A non-transparent mask has a distributed series of openings which accord with a series of colour filters. The mask is over the lens cage, and relatively movable to fit. Other arrangements include variations in the lens curves, colour filters below the lenses or on them. Three dimensional work is possible in addition to ordinary photography and projections but with polarised spectacles worn for viewing.

Title: Automatic centring of electric conductor in insulation sleeve - uses signal pulse gating unit automatically calibrated during preset time intervals by means of CRT display
Inventor: DOMORAZEK GOTTFRIED DR
IPC: B29C48/92
Filed: 1975-10-08
Abstract: A signal pulse is used for automatically centring an electric conductor in an insulating sleeve. The pulse gating unit is automatically calibrated during predetermined time intervals by comparing the received measurement pulse with predetermined nominal values. The measurement pulse is picked up with a calibration-cable balancing network and brought into the beam path of a CRT. Spatially limited interference from points on the insulation shell is tuned out in the video signals from which (signal) is formed a threshold signal converted into a positive output. This reverts to zero only when one complete line of the picture on the target is dark.
