Title: Magneto-optical information storage device - contg. epitactic layer of substd. iron garnet
Inventor: KRUMME JENS-PETER DR
IPC: G11C13/06
Filed: 1973-07-21
Abstract: Magnets-optical information storage device comprising a raster consisting of thermally controllable closed compensation domain walls made of a material contg. a magnetically compensated epitactic layer of a substd. iron garnet having the compsn. Dg3-xAxFe5-yByO12 (in which A is a rare earth element ion; B is Ga or Al, y 0.8) or Y3-xo-AxoFe5-yoByoO12 (in which A is a trivalent rate earth element ions from Sa3+ to Yb3= and B is Ga3+ and/or Al3+, or a combination of ions Si4+, Ge4+ and/or V5+ with Ca2+, Mg2+ and/or Zn2+; when xo is 0, 1 =yo =2; when 0 xo =3, 0 =yo =2), showing a linear range (compensation line) in which the saturation magnetisation is mull, is improved in that the raster consists of islets (produced with the use of a silicon mask) in which the compensation temp. is increased (the islets are kept below this temp.), and the local domains remaining after tempering and removal of silicon islets can be reversibly extinguished by raising the temp. above the compensation temp. Light-scanning can be used for this purpose. The Faraday rotation of the material can be increased by introducing Bi3+ or Pb2+ ions into the dodecahedral sites of the crystalline lattice. There is no need to change the iron garnet crystalline lattice so that the mfr. is greatly simplified. High storage density can be achieved.

Title: Automatic door closer floor panel - has base frame for door closer mechanism supported by height adjustable legs
Inventor: DECKER KARL-HEINZ
IPC: E05F3/00
Filed: 1974-04-22
Abstract: The closer mechanism of an automatic door needs to be flush, which often presents a problem. On previous designs it was usual to fit the housing beforehand, which then was embedded in the concrete layer of the floor. This resulted in inaccuracies due to the rough handling of the housing during the pouring of the concrete. This is obviated by having the frame rest on adjustable legs to raise the closer mechanism after the concrete has set. The heigh of these legs can be accurately adjusted to be flush with the surroundings finished floor level. There are at least three feet with screw adjustable attachments to the frame, which can be rotated from above to achieve the required raising or lowering.
