Title: Magnetic disc for sound and pictures reproduction - uses magnetic circular films on metallic discs
Inventor: HARTMANN JOB-WERNER DIPL CHEM
IPC: G11B5/845
Filed: 1973-11-17
Abstract: The film undergoing the magnetisation process may be applied to both sides of the metallic disc. The film is a mixture of binding material and anisotropic magnetic particles and is applied on the disc in a liquid form. It is spread by centrifugal force, with the disc rotating at high speed. It is magnetised, hardened, ground and then polished. One pair of poles is so arranged that magnetism spreads into the symmetrical plane and forms another even shaped pole pair but of opposite polarity and which converges pointed to the symmetry plane. The distance between the magnetic crests is greater than that of the pole faces and the flux density greates near the poles. The position of the poles is adjustable; during the film application they move toward each other. With this method of film application the reading potential is improved by 50%.

In this way the beakers can be economically stored with their holders.
Patent DE-2400346-A1 (DE)
Title: Ring laser closed loop optical cavity system - has light reflecting frequency biasing element for phase shift imparting
Inventor: MACEK WARREN MICHAEL
IPC: G01C19/68
Filed: 1974-01-04
Abstract: The optical cavity system contains the active laser medium, transmitting light beams in opposite direction. The light beams propagate in the optical cavity along a closed circulation path. The optical cavity incorporates a light reflecting frequency biassing element, imparting a phase shift to the oppositely propagated light beams. The reflecting element consists of several layers, including a magnetisable layer coated with a dielectric film. The layer thickness is determned in dependence to the refractive index of the electric film, the wavelength and the impact angle of the light beams on the reflecting element. Thus the differential reflection of the light beams, propagating in opposite owing to is removed, which would otherwise appear owing to the magnetisable layer. On the other hand, the non-reciprocal phase shift, caused by the layer, is retained.

Title: Potato peeling machine - with bar grating centrifugal drum raisable from bottom plate for discharge
Inventor: WERNSING HEINRICH
IPC: A23N7/01
Filed: 1974-09-07
Abstract: A potato peeling machine consists of a vertical centrifugal drum with a bar grating, surrounded by a trough to collect the peelings and a discharge duct. The bottom of the drum which can be driven at a high speed can be sepd. from it by an axial relative movement so that a discharge opening for the peeled potatoes is created.
