Title: Telephone PBX operating when called subscriber answers - transmits marked position of central selector to individual selector
Inventor: DIRR JOSEF ING GRAD
IPC: H04Q3/62
Filed: 1977-05-27
Abstract: The PBX has switching systems which divide the selectors (line finders and line selectors) of the internal connecting set, or equivalent equipment, in and individual part (AS) and in a central part. The call can be made in the individual or central part. The call can be made in the individual or central part, with subsequent engagement of the central or individual part. When the called subscriber answers, only an individual selector switches through the connection to both subscribers, so that when a starter and a finder switch are engaged, a central or individual selector is connected to it. Acoustic signals are transmitted through the connecting wires, and a call and a retransmission is carried out through the line selector part. When the called subscriber answers, switching means become operative and transmit the marked position of the central selector to the individual selector, with corresponding second setting of the market selector in the central part.

(I) and cpds. H2N-(Prop-NH)pH, where p >=4, are made by reacting hydrogenated reaction products of ethylenediamine with acrylonitrile of formula H2N-Eth-NH-Prop-NH2 or H2N-Prop-NH-Eth-NH-Prop-NH2, and/or oligomers of propylenediamine with >=2 propylene units/mol. alone or with propylenediamine-1,3, with a catalyst of a gp. VIII metal at 50-250 degrees C with splitting off of ammonia. Pref. after the reaction polyalkylenepolyamines with =3 alkylene units/mol. are sepd. from the reaction mixt. and returned to the reaction. The process is relatively simple and required fewer process stages than prior art processes. Undesirable cyclisation of the prod. is reduced to a min. and compared with some previous processes, the amt. of effluent produced for disposal is very small. The prods. are useful e.g. in papermaking and as sedimentation aids. (I) have good solubility in water compared to uniform polyalkylenepolyamines.

Patent DE-2848791-A1 (DE)
Inventor: QUAST GERHARD
IPC: G01R19/15
Filed: 1978-11-10
Abstract: High-voltage direct or alternating currents, particularly heating currents in passenger train coaches, are to be monitored with isolated potential and errors are to be indicated. To achieve this object, it is proposed to control an optocoupler (8) directly via the voltage drop across an indicator resistor (5) through which current to be monitored flows. For this purpose, the receiver transistor (10) of the optocoupler is connected to an evaluating circuit (11) which switches off a LED display diode (18) in dependence of the flowing of the current in the indicator resistor (5). To monitor alternating currents, the evaluating circuit (11) is additionally associated with a timing element (15) which delays a lighting-up of the LED display diode (18) in the half periods of the current in which the optocoupler (8) is blocked depending on the direction of the current. In arrangements having a control contactor for additional current or temperature control, the normally-open contact of which is connected in series with the heating groups to be switched, an auxiliary contact (3b) of the control contactor (3) bypasses, when the current is operationally interrupted by the normally-open contact (3a), the receiver transistor (10) of the optocoupler (8), which is then cut off, the base current being supplied to a control transistor (13) of the evaluating circuit (11) via a parallel path. <IMAGE>
