Patent DE-3223292-A1 (DE)
Inventor: NAGLER WERNER DIPL ING
IPC: H04M19/00
Filed: 1982-06-22
Abstract: 1. A circuit arrangement for determining the switching state of a subscriber connection line (TL) in telecommunications systems, the line wires (a, b) of which are each connected to one of the two poles of the supply voltage source (UB) via a supply element which, for switch-over between high-ohmic and low-ohmic supply, can in part be bridged in low-ohmic fashion by means of switching means (Ka, Kb), by evaluating the potential state at line-wire-related, fixed coupling points in the subscriber connection circuit which forms the exchange-end terminal of the respective subscriber connection line, with an indication circuit (K) which, by means of a cyclically operated, first electronic selection switching element (A1), can be consecutively connected to a plurality of subscriber connection lines, and which, in dependence upon the operating state of each subscriber connection circuit, set by a central contral device, is used to carry out different kinds of indications, for which purpose it is supplied with different reference voltage values which depend upon the nature of the indications, with capacitors (CS) which can each be separately connected by means of a second electronic switching element (A2) for the indication circuit (K) in dependence upon the switching position of the first selection switching element (A1), and which can be actuated in dependence upon the nature of the indication which is to be carried out, and which each serve for filtering purposes, and with switching means (kr) which serve to connect an a.c. ringing voltage (UR) to the wires of the subscriber connection line, characterized in that the first and second electronic selection switching elements (A1, A2) are each temporarily blocked in respect to the passage of current in the event of a switching position change in excess of the duration of the respective switching process, and that the first selection switching element (A1) is blocked in respect of the passage of current in the event of the connection and disconnection of the ringing a.c. voltage (UR) during a time which corresponds to the response- and drop-out times of the aforesaid connection means (kr) and switching means (ka, kb) which effect a switch-over between high-ohmic and low-ohmic supply.

Patent DE-3227063-A1 (DE)
Title: Process and plant for separating off arsenic in metallurgical processes, in particular for removing arsenic from arsenic-containing waste gases
Inventor: PESCH THEO
IPC: C22B7/02
Filed: 1982-07-20
Abstract: In the pyrometallurgical treatment of arsenic-containing sulphide ores, for example copper ore concentrate or lead ore concentrate, which is carried out at high temperatures and high oxygen potentials, hot waste gases are formed in which the arsenic is volatilised as arsenic oxide. To remove the arsenic or to recover the arsenic from the arsenic-containing waste gases, it is proposed according to the invention that the waste gases are contacted with an aqueous solution and the arsenic contained in the waste gases, especially arsenic oxide from the gas phase or vapour phase, is transferred into the aqueous solution, from which the arsenic is precipitated by cementation, especially in a vibratory cementation reactor, by means of an electrochemically less positive cementation metal such as, for example, scrap iron or granulated zinc, formation of the highly toxic arsenic hydride being avoided in this cementation by maintaining the stability range of elemental arsenic and/or the alloys or compounds thereof with the cementation metal.
Patent DE-3231208-A1 (DE)
Title: Circuit for dynamically altering the resolution of a visual display unit
Inventor: GUDE MICHAEL
IPC: G09G5/18
Filed: 1982-08-21
Abstract: In the case of digital display units with line-by-line scanning (raster scan) of the picture, as a rule all the required signals are derived from a quartz-stable input frequency. This applies in particular to the synchronising signals of the monitor. If the number of picture elements per line is then altered, all frequencies dependent thereupon shift correspondingly. So in order to keep line and picture frequency constant, the input frequency must be correspondingly altered. Without a control circuit, the effort this involves is very great. The purpose of the present invention is to minimise this effort. This is achieved by the input frequency for picture generation being generated by a highly stable voltage-controlled oscillator. This oscillator is always controlled by a correction signal in such a way that the line frequency remains constant. The correction signal is obtained by a frequency and phase comparator. This comparator constantly compares the generated line frequency with a quartz-stable reference line frequency. Consequently, this control circuit keeps the synchronising frequencies constant even when the number of picture elements alters. If controlling takes place quickly, the resolution can also be dynamically altered, and thus a quasi-continuous zoom effect is obtained.
Patent DE-3238026-A1 (DE)
Title: Method of degassing, purifying and reproducibly mixing liquids in the field of chromatography
Inventor: KAGE ANDREAS
IPC: G01N30/34
Filed: 1982-10-11
Abstract: This method is based on a system which consists of one or more primary reservoirs and a secondary reservoir which are interconnected by filters, pumps and valves in such a way that conveyance of the liquids from the primary reservoirs into the secondary reservoir via various filters is possible. After a single degassing of the liquids in the primary reservoir, it enables purification and reproducible mixing of the liquids of the primary reservoirs, it being possible to retrieve the degassed, purified and optionally mixed liquids without further possibility of contamination with soluble gases or impurities from the secondary reservoir. A multiplicity of undesirable impurities can be removed from the liquids by suitable choice of the filters; a microbial contamination in the secondary reservoir is avoided.

Title: Titan-, zirkon- und/oder hafniumhaltige zeolithe und verfahren zu ihrer herstellung sowie ihre verwendung
Inventor: BALTES HERBERT DR
IPC: C07C11/20
Filed: 1982-11-05
Abstract: Die Erfindung bezieht sich auf einen Fühler zur Bestimmung der Standhöhe von flüssigen Gasen. Das die Standhöhe der Flüssigkeit anzeigende elektrische Signal wird dabei mittels eines temperaturabhängigen Widerstands gebildet. Die der Erfindung zugrundeliegende Aufgabe besteht darin, einen Fühler der vorgenannten Art zu schaffen, mit dem eine eindeutige Bestimmung der Standhöhe des flüssigen Gases möglich ist. Der Fühler zeichnet sich dadurch aus, daß er neben dem die Standhöhe anzeigenden, temperaturabhängigen Widerstand einen weiteren elektrischen Widerstand aufweist, der mit einer elektrischen Spannung beaufschlagt wird. Dadurch wird der Fühler, wenn er sich außerhalb der Flüssigkeit befindet, stärker erwärmt, als wenn er in der Flüssigkeit eingetaucht ist. Das führt zu einer merkbaren Signaländerung beim Eintauchen in die Flüssigkeit bzw. Heraustreten des Fühlers aus der Flüssigkeit. Bei einen Fühlersystem der in der Zeichnung (Fig. 3) dargestellten Art pendelt die Standhöhe der Flüssigkeit zwischen den Positionen der beiden mittleren Fühler "voll" und "nachfüllen". Die beiden übrigen Fühler dienen im Fall des Überlaufs und bei leerem Behälter zur Alarmanzeige.

Patent DE-3336164-A1 (DE)
Title: Flow-type cell
Inventor: MAYER PETER
IPC: G01N21/05
Filed: 1983-10-05
Abstract: A flow-type cell (1) is used to study liquids containing at least partially soluble solid particles in suspension and, possibly, air or gas bubbles. It is intended, in particular, to enable the dissolution behaviour of pharmaceutical tablets or powders to be studied. For this purpose, the cell (1) has a turbulence device upstream of a measurement zone (3) in the flow direction and further upstream of the measurement zone (3) a removal channel (5) for any gas or air inclusions. In addition, provided downstream of the measurement zone (3) in the flow direction is the drain (6) which is connected to the suction connection (4). The turbulence device ensures, on the one hand, a uniform distribution of the solid particles to obtain correspondingly uniform measurement results, while, on the other hand, bubbles are thereby separated off so that they can be sucked off in an upward direction. <IMAGE>
Patent DE-3408882-A1 (DE)
Title: Rotary tapered-circumference helical nozzle
Inventor: GOERES HANS DIETER WILHELM
IPC: B64C11/00
Filed: 1984-03-10
Abstract: The rotary tapered-circumference helical nozzle is a nozzle for propelling aircraft, watercraft, underwater vessels and land vehicles (e.g. locomotives). This nozzle has a rotating inner funnel part which in addition can also have a helix, i.e. spiral-profile guide elements (welded on), on the inside. The medium (hot gas, air or water) flowing through the entire nozzle thereby covers a spiral path with regard to the tapered-circumference part (rotating funnel part), as viewed from the funnel part. This is consequently a longer path in the same unit of time, and therefore greater suction results than when the tapered circumference of the nozzle is stationary. There is greater pressure in the front part of the entire nozzle behind the inlet, where the tubular cross-section of the nozzle at first widens, in contrast to the rear part of the entire nozzle, which rear part narrows conically and is rotated under an outer protective envelope. Before leaving the nozzle, the medium also passes through a short non-rotating cylindrical or conical outlet piece. The nozzle and the vehicle or vessel fitted with it is propelled in interplay with the repulsion, with better utilisation of the flow thereby obtained. Thus possibilities of operating nozzles without hot gas also arise. For starting from the standing position, medium can be scooped or pumped in by a helical mouth; this "screw mouth" can also be attached directly in front of the rotary tapered circumference. Further variants and various applications can be gathered from the description ... Original abstract incomplete.
