Patent DE-3039432-A1 (DE)
Title: Constant DC supply for telephone instrument - has feed into one line with balancing impedance connected to other line
Inventor: GRUENER PETER ING GRAD
IPC: H04M19/00
Filed: 1980-10-18
Abstract: The constant current source (1) feeds into one line (La) of a two wire connection to a subscriber instrument (Tln). The return to the dc source negative from the other line (Lb) is via an impedance, typically a choke, to provide symmetry between the lines and supply potential. The impedance of the source (1) and choke should be equal. In a practical circuit, the choke is simulated by a capacitor and transistor configuration. A transistor (Ts1) is connected as an emitter follower and may drive a second transistor (Ts2). The emitter potential tends to be held constant by the capacitor (C1) thus any change in current through the transistors due to a change in applied potential is slow and simulates the response of an inductance.
Patent DE-3039600-A1 (DE)
Inventor: RASSHOFER WERNER DR
IPC: C08G18/50
Filed: 1980-10-21
Abstract: A compound having a terminal isocyanate group is hydrolyzed to produce a polyamine having a urethane and/or a urea and/or a biuret group. More particularly, a carbamate is made by mixing an isocyanate prepolymer having urethane and/or urea and/or biuret groups present with aqueous base solutions at a temperature of from 0 DEG  to 0 DEG C. and in quantities such that the equivalent ratio of hydroxyl to isocyanate groups is between from 0,3:1 to >/=1,01 to 1. The carbamate is then treated with an acid ion exchanger to form an amine. The amine is then removed from any other material which may be present. A preferred polyamine thus-produced corresponds to the general formula:   <IMAGE>   in which each R radical may represent a divalent straight or branched- chain aliphatic radical; a divalent cycloaliphatic radical; a 4,4'- and/or a 2,4'-dicyclohexylmethane radical; or a 2,4- and/or 2,6-methyl cyclohexane radical. Such an amine may be reacted with a polyisocyanate and optionally with other known additives to form a polyurethane plastic or foam.
