Title: Cast housing shell for laminated stator core - has prismatic abutting surface and longitudinal slot provided in casting
Inventor: BOESCHE JUERGEN ING GRAD
IPC: H02K5/06
Filed: 1974-07-05
Abstract: The cast housing (2) encloses a machine laminated stator core and is cast with a slot along its length to allow it to be pulled tightly around the outside surface of the stator (1).

Title: Rendering signals into digital form - signals analog representation by scanning with slow motion effect
IPC: H04B14/02
Filed: 1974-08-23
Abstract: The signal function for digital form representation of it is equidistantly scanned, or stochastically, or through a combination of both scanning modes, at less than the Nyquist rate, with no ambiguities arising. Through a special mode of treatment of the scanned values a slow motion effect is produced. The input frequency range is considerably enhanced without increased costs and enables derivation of correlation function of two signal forms. Errors can arise when the scanning distance are not accurately positioned, but they can be neglected by a corresponding selection of probability function with respect to the unavoidable errors arising by the D/A conversion of the input signals.
Patent DE-2456021-A1 (DE)
Title: Rechargeable sodium-sulphur battery - contains sulphur in graphite felt filled electrolyte tubes inside sodium soaked metallic felt
Inventor: BAUKAL WERNER DIPL CHEM DR
IPC: H01M10/39
Filed: 1974-11-27
Abstract: A rechargeable sodium/sulphur battery contains the sulphur, absorbed in graphitic felt, in containers made of a ceramic electrolyte (beta Al2O3). Several of these containers are arranged inside a common tank, filled with electrochemically active sodium. This sodium is entirely absorbed in metallic felt which takesup the space in the tank which is not occupied by the containers. This prevents corrosion of the case by sulphur or polysulphides. The common sodium reservoir results in a high specific energy. The intercel resistance is reduced by the metallic felt and sodium cannot leak out in case of a breakage. The battery can be used in any position; its design is simple and it is not expensive to manufacture.
