Title: Circuit arrangement for a low-frequency generator with a controllable output voltage
Inventor: HAHN EBERHARD DIPL ING
IPC: H04M19/04
Filed: 1982-07-15
Abstract: The invention relates to a circuit arrangement for a low-frequency generator with a controllable output voltage for telecommunications systems, in particular telephone systems, where the low-frequency generator is powered by a DC voltage wave. By means of the switching stage (T3) disposed in the primary circuit and controlled with the clock generating device (TG), the flow converter (U1) generates partial voltages which are converted by the push-pull amplifier device (GV), depending on the frequency of the generator device (GE) controlling the push-pull amplifier device (GV), into the low-frequency voltage (UA1, 2). Low-frequency generators of this type are used in telephone systems. <IMAGE>

Title: Liquid filling needle
Inventor: BULLINGER SIEGFRIED
IPC: B65B39/00
Filed: 1982-08-04
Abstract: The liquid filling needle has a delivery tube (61), a feeding pipe (71) opening into the outflow end of the delivery tube (61) at a distance from it and a liquid shut-off valve (73) which can be controlled by a drive device (81) and is situated in the flow path of the liquid between the feeding pipe (71) and the outflow end. The liquid in the delivery tube (61) is connected to the inside space (57) a cylinder (53) in which a piston (55) which is sealed off from the inside space (57) is displaceably arranged. The drive device (81) of the shut-off valve (73) or another drive device displaces the piston (55) towards an extension of the interior of the cylinder (53) while and/or after the shut-off the valve (73) is locked. In this way, dripping of the delivery tube when filling has been completed is avoided by elastic extension of the flexible tube forming the feeding pipe. The piston either sucks excess liquid out of the flexible tube or back from the delivery tube, depending on whether the shut-off valve is located upstream or downstream of the piston/cylinder assembly. <IMAGE>

Inventor: NESTLER HANS JUERGEN DR
IPC: C07C67/08
Filed: 1983-10-05
Abstract: Carboxylic acids containing phenol groups are esterified by means of (C1-C3)-alcohols in the presence of acid catalysts without the phenolic hydroxyl groups being esterified at the same time by continuously metering an excess of a water-containing (C1-C3)-alcohol into a boiling hot solution or suspension of the phenol-containing carboxylic acid and of the catalyst in a non-water-miscible solvent (for example xylene) and at the same time distilling off a ternary solvent/alcohol/water mixture via a water separator, the metering rate being such that an aqueous bottom phase separates out in the receiving flask and the water content of the alcohol being so apportioned as not to breach the bottom limit of 0.1% or the upper limit of 1% (based on the contents of the reaction vessel) at any time in the course of the reaction. In this process, the esterification products are obtained free of major impurities and frequently can be used further without further purification.

Patent DE-3410198-A1 (DE)
Title: Device for connecting wall elements
IPC: F16B19/02
Filed: 1984-03-20
Abstract: Connecting elements for panel-shaped or box-shaped wall elements are formed from two preferably identical frustoconical portions (2, 2%) which taper towards the outside and between which a cylindrical portion (5) extends. These wall elements are introduced into corresponding frustoconical bores in mutually opposite wall elements and a stable connection is thus produced which, at the same time, gives the wall elements a certain freedom in expansion and shrinkage as a result of temperature changes. Connection between a wall element equipped with the connecting elements and the wall element to which it is intended to be connected can be non-visible, i.e. blind, since the frustoconical bores act as introduction funnels. In addition, the cylindrical connecting portion can be left out or, if appropriate, replaced by a collar with an enlarged diameter, in order to form defined gaps between neighbouring wall elements. <IMAGE>
