Title: Hollow plastic dialysis fibres having oil removed - by solvent vapours in enclosed chamber
Inventor: SIGDELL JAN-ERIK DR
IPC: B01D12/00
Filed: 1980-02-09
Abstract: Bundles of hollow plastic fibres used for dialysis have oil removed from their outer (and possibly inner) surfaces by the vapour of a solvent held in the base of an enclosed chamber. The solvent may be unheated when removing oil from the exteriors only. For treating the interiors the effect is strengthened by heating the solvent to b.pt. Vapour is condensed at the top of the chamber and falls back round and through the fibres for re-use. The pressure in the chamber can be varied so that air between sepd. drops of solvent inside the fibres pushes the drops up and down to promote dissolution. Oils are used in mfg. hollow fibres and must be removed before dialysis. This is pref. effected by the single-stage (hot solvent) method, instead of separate stages for the interiors and exteriors, and no pump is required.

Title: Digital conversion of TDM into frequency multiplex signals - using low pass and high pass filters for different signals for obtaining desired channels
Inventor: GOECKLER HEINZ DIPL ING
IPC: H04J4/00
Filed: 1980-02-28
Abstract: In the conversion system the frequency multiplex signal consists of stagewise groups. Every two signals form a group signal with doubled channel number. One signal is used to form a sweep position, while both signals double the scanning frequency. Then the process signals are combined by two filters, or by a complementary filter. One signal is passed through a low pass filter, the other through a high pass filter. For a specified channel number each stage of the entire arrangement is formed by an identical elemental structure. If three signals are used the scanning frequency is tripled. Pref. the first two signals are combined by passing through filters, and the combined signal is then combined inthe same manner with the third signal. Alternately, only the third signal is filtered and added to the combined signal by a summation element. Typically, digital wave filters are used as complementary filters.
