Title: Circuit arrangement for monitoring the operating range of an operational amplifier
Inventor: STRAUB HERBERT DIPL ING
IPC: H03F1/52
Filed: 1983-02-18
Abstract: The invention relates to a circuit arrangement for monitoring the operating range of an operational amplifier (OP). For this purpose, the operational amplifier (OP) is followed by a rectifier bridge circuit (D1...D4) in the DC branch of which the light-emitting-diode section of an optocoupler (OK) is arranged. A monitoring circuit (ÜS) is used for detecting when the phototransistor of the optocoupler becomes conductive. A fault indication can then be triggered. The operating range of the operational amplifier to be monitored is set by a Z diode (Z) which is connected in series with the light-emitting-diode section of the optocoupler. To protect the light-emitting diode of the optocoupler against overload, a series resistor (RV) can be additionally connected in series with the light-emitting-diode section of the optocoupler and the Z diode. <IMAGE>

Patent DE-3343978-A1 (DE)
Inventor: BECHEM WERNER
IPC: C25D5/02
Filed: 1983-12-06
Abstract: There is disclosed a method and a device for the continuous electrolytic deposition of metals from aqueous solutions of metallic salts onto a metal strip using a high flow speed of the electrolyte between anode and cathode in order to obtain high current densities at relatively low voltages, especially for the electrolytic coating of steel strip with non-ferrous metals, preferably with zinc. In order, particularly, in the case of a one-sided strip coating, to set and be able to regulate a very small distance between anode and cathode, these is thereby achieved low voltage losses in the electrolyte and a correspondingly lesser development of heat, while inducing a very rapid exchange of the electrolyte in the space between anode and cathode. There is obtained a high current density. Finally, not to adversely affect the industrial qualities of the strip by a very low friction of the strip to be coated, it is disclosed that the metal strip as cathode be passed along a rotating cylindrical anode and that fresh electrolytic solution be constantly introduced into the space formed between anode and cathode.

Title: Method for preventing misuse in telecommunications networks, in particular mobile radio networks
Inventor: DIEDERICH HANS G DIPL ING
IPC: H04W12/06
Filed: 1984-05-11
Abstract: In a telecommunications network, in particular a mobile radio network, with subscriber-individual identification codes for call charge registration and identification, the computer-aided recognition of identification codes thus transmitted in encoded form following monitoring, for example, of the radio traffic is intended to be rendered more difficult. For this purpose, a set of function-specific identification codes is allocated to each subscriber which are used exclusively in specific phases of the incoming or outgoing connection set-up or its preparation. For example, in a cellular mobile radio network with a central organisation channel, the booking-in or re-booking preventively performed therein of each subscriber entering the radio traffic area is carried out using an identification code K1, whereas the booking-out is performed using a different identification code K3. The outgoing dialling information is likewise transmitted using a different identification code K2 which likewise differs from the identification code K3 for the response to incoming dialling information (Fig. 1). <IMAGE>

Title: Process and device for testing the delivery rate of mixing devices for multi-component plastics, in particular polyurethane
Inventor: KNEIFEL VOLKER
IPC: B29B7/76
Filed: 1984-06-14
Abstract: The process and the device for testing the delivery rate of mixing devices for multi-component plastics use essentially the existing mixing device for testing. Only one inlet opening 2 is sealed, for example by a blind plug 3, and only one component is delivered into the mixing chamber. The amount of component collected can then be weighed so that the amount per unit time can be calculated. The closure of the other inlet opening or of the other inlet openings, if more than two components are provided for mixing, prevents the component delivered for testing from entering the region of the other components. In an advantageous manner, the blind plug can be designed as a switch so that the delivery of the selected component to be tested is only possible when the blind plug assumes its desired sealing position. The blind plug is used, for example, instead of an injection nozzle normally provided. <IMAGE>

Title: Process for converting water or like fluid from the liquid phase into the gaseous phase and apparatus for carrying out this process
Inventor: HENDEL HORST DIPL ING
IPC: C02F1/14
Filed: 1984-12-22
Abstract: In a process and an apparatus for vaporising liquids with the aid of a carrier gas taking up the vaporised component of the liquid, this carrier gas is forced via inlet orifices (2), which are distributed in individual tubes (4), into the liquid (5) and/or sucked through the liquid. As a result, this liquid passes into a state of effervescing bubbling similar to a boiling process, so that the vaporisation surface is considerably enlarged. The carrier gas is enriched by this means up to the region of saturation with the gaseous component of the liquid. A cooling of the carrier gas also takes place in this case. The carrier gas is then conducted through a liquid particle-retaining intermediate screen (6) to an outlet orifice (3). <IMAGE>
