Patent DE-2264905-A1 (DE)
Title: Electrically controlled shutter for SLR camera - allows precise adjustment even at very short exposures
Inventor: MIYAKAWA SEINEAN
IPC: G03B7/26
Filed: 1972-05-10
Abstract: Assembly for electrically controlled shutter of single-lens reflex camera comprises a photoelectronic component on the image side of the objective for measuring object light intensity, and a circuit for controlling a shutter-closing electromagnet according to a signal from the photoelectronic component and other signals relating to remaining paramenter. Shutter closure for exposure times below a given value e.g. (1/500 secs.) is controlled mechanically by a switching member mechanically coupled to an adjuster of manually adjusted exposure times. On adjustment to a short exposure time, the switching member lowers the response threshold of the control circuit, so that the energising circuit for the electromagnet becomes non-conductive at the latest immediately after opening of the shutter.

Title: Crosslinking or hardening of insulating layers on wires - uses irradiation by high energy electrons in evacuated chamber coupled to electric tube
Inventor: KUHN ERNST DR
IPC: G21K5/10
Filed: 1973-08-14
Abstract: The processing irradiation takes place in an evacuated chamber which is connected to the evacuated electron tube by a narrow channel permitting the passage of the electron beam. The wire coated with an insulating film, to be irradiated, is fed to and discharge from the vacuum chamber via vacuum closures with seals. A magnetic field with force lines parallel to the wire may be generated in the irradiation chamber by magnetic oils or permanent magnets, and the magnetic field may be changed in time by heterodyning frequency. Further electron tubes may be mounted on the chamber and the magnetic field is then common to all beams.

Title: Photographic printing typewriter - reflecting mirror system controls illuminated character exposure followed by instant developing
Inventor: KLUGE GERHARD A
IPC: B41J2/435
Filed: 1973-08-29
Abstract: The main advantages of the method are due to the elimination of noise associated with conventional typewriters, few mechanical components, as well as no restriction in the number of printed signs. The keyboard is connected to the printed circuit of the different characters with the possibility of cancellation of single signs or of a line. Reflecting mirros direct the beam from a flash lamp to photo film which is fed to developer which delivers the slowly flowing reagent fluid. The drips of the latter along an inclined path are caught in a vessel below with a pump feeding back the residue to the developing fluid tank.
