An electrically conductive polythiophene or substituted polythiophene, a procedure for its manufacturing and its use. The electrically conductive polythiophene or substituted polythiophene has been doped or treated with FeCl3 or with compounds containing FeCl4 anions. The electrically conductive polythiophene or substituted polythiophene is manufactured by treating it in a way known in itself in t...

The invention relates to a process for the preparation of a compound of general formula (I) (I) wherein R1 represents a hydrogen atom or a C1-10 alkyl, C3-7 cycloalkyl, C3-7 cycloalkyl-(C1-4)alkyl, C3-6 alkenyl, C3-10 alkynyl, phenyl or phenyl-(C1-3)alkyl group, and one of the groups represented by R2, R3 and R4 is a hydrogen atom or a C1-6 alkyl, C3-7 cycloalkyl, C2-6 alkenyl or phenyl...

An arrangement for a closed system for transferring a liquid from a vessel to a collection container (6) which are attachable to each other via a coupling member (17) with a two sided cannula (2). One end of the collection container (6) is closed by a seal (7) which can be penetrated by the cannula (2). Behind the seal inside the container is a plunger (8) with an axial penetrating canal to which ...

A circuit arrangement for suppressing interference signals on the receiving arm of a subscriber line circuit is constructed from electronic components and thus comprises no speech transformers. The receiving arm of the subscriber line circuit (SLIC) is connected to a two-pole filter circuit (ZF) which consists of the parallel arrangement of a parallel-and a series-resonance circuit (LP,CP and LS,C...

The mounting has one attachment implanted in the body and a second secured to the prosthesis. The first attachment has sockets (3) in the body, the upper parts having positioning openings. A splint (4) is anchored to the sockets by screws (6). The second attachment has V-shaped clips (7) which snap over the splint. The splint can be curved and can have apertures for the attachment screws. Alternat...

The foil strip runs over a part at the outer surface (10) of a rotating drum (3). The cutting blade (8) has the same length as the drum in which it is fitted with its cutting edge (9) standing slightly proud of the drum surface. - The blade can move between a starting point where its cutting edge is in front of the drum outer surface (10), and a cutting position where its edge is extended somewhat...
