Title: Schaltungsanordnung zur Übertragung von zu einem Referenzpotential symmetrischen Nachrichtensignalen
IPC: H04B3/30
Filed: 1983-04-08
Granted: 1986-02-20
Abstract: Es wird ein Schaltungsanordnung angegeben, mit der ein zu einem Referenzpotential (z.B. Erdpotential) symmetrisches Nutzsignal in einem zu diesem Referenzpotential symmetrisch ausgebildeten Stromkreis übertragen werden kann und dabei auf das Referenzpotential bezogene, unsymmetrische Störsignale unterdrückt werden können. Hierzu werden zwischen die Leiter (a und b) des symmetrischen Stromkreises und das Referenzpotential positive Impedanzen (23 und 24) geschaltet, welche eine Dämpfung der Störsignale bewirken. Die durch die positiven Impedanzen ebenfalls verursachte Dämpfung des zum Referenzpotential symmetrischen Nutzsignals wird durch Einschalten einer negativen Impedanz (-Z) zwischen die Leiter (a, b) kompensiert, so daß das Nutzsignal ungeschwächt erhalten bleibt.

Filed: 1990-02-28
Granted: 1994-06-09
Abstract: The invention is based on a method for making rubber mixtures, in which, in a first stage, a basic mixture is prepared in an internal mixer (1) with floating weight and, in a second stage, a finished mixture is prepared in an internal mixer (9) without floating weight in batches, to be precise dispensing with intermediate storage. In order to improve the cooling in the internal mixer without floating weight, according to the invention its inner space is charged with air (13, 14) which is of a dryness avoiding the precipitation of condensation. To achieve the same, there is provided between the two internal mixers a substantially air-tight duct (8), in which there is also space for the bottom closure of the internal mixer with floating weight, in the swung-out state.
