Title: Soft magnetic closed laminated cores - are finished by injecting expanding material into fringe areas of laminations
Inventor: LEHMANN KARL-OTTO PROF DR
IPC: H01F27/245
Filed: 1973-08-06
Abstract: A compact closed magnetic core of soft magnetic laminations is obtained by injecting into the outer and/or inner fringe areas an expansion material which has a thermic expansion coefficient different from that of the soft magnetic material of the laminations and that at the working temperature the other parts of the laminations are kept in the contour plane under mechanical tension. The fringe areas of the laminations may be sprayed before assembly on both sides by means of a shutter mask with the expansion material which penetrates into the laminations by diffusion. The method is applicable also for laminations of less than 30 micron thickness. The method is suitable for ring- and square-shaped laminations and results in improved magnetic properties such as steepening of the hysteresis loop and magnetisation curve of the soft magnetic lamination material.

Title: Flexible coupling for large pipe line tubes - hydrogen separated by a temperature pressure system from the steam mixture is recirculated to combustion chamber
Inventor: SLJUSAR ANATOLY EMELYANOWITSCH
IPC: E21B17/20
Filed: 1974-03-28
Abstract: When inserting pipe line tubes down drill holes, it is an advantage when the joints between the tube sections are flexible to allow correction of axial alignment. This is achieved by using a coupling ring with a spherical outside diameter. One tube end is provided with a sleeve which has an internal spherical seat for the coupling ring. The end of the other tube which has an external groove fits inside the coupling ring. It is held there by retainer blocks which are inserted radially through slots in the coupling ring. The blocks which are held in position by springs engage the external groove on the tube end thus retaining it in position.

Title: Peeling of root vegetables - in a high pressure vessel with locks to allow continuous feed and offtake at atm. pressure
IPC: A23N7/00
Filed: 1974-04-09
Abstract: Potatoes and other root vegetables may be peeled in a high pressure vessel with a transporter. The feed and off-take occur via pressure locks which can be closed off from the pressure vessel and from the atmosphere.
