Patent DE-4319764-A1 (DE)
Title: Measuring device for determining the parameters, such as frequency response and directional response, characterising a microphone
Inventor: SEIDEL FOLKE DIPL PHYS
IPC: H04R29/00
Filed: 1993-06-15
Abstract: The aim of a microphone measuring method is to determine the acoustic properties (characteristics) of a microphone to be tested (test specimen). In order to carry out the measurement method even in a space, affected by reflection, of a small measuring box which is substantially smaller than the conventional ideal measuring space, a three-stage measurement method is proposed. In a first method step, a calibration microphone is used which is calibrated and supplies a known defined relationship between the sound pressure and the microphone output voltage. As a result, it is possible at a specific point in the prescribed sound field to use the output voltages to determine both sound pressure and the vectorial sound pressure gradient. In a second method step, the test specimen is then brought to the same point in the sound field and exposed there to two different operating conditions. The two output voltages which arise in this case are measured. In a third method step, the results of the preceding method steps are used to calculate the two parameters of a formula which represent the parameters characterising the test specimen. With the aid of these parameters, the output voltage of the test specimen, which is a function of the angle of incidence of the sound, can be calculated for an arbitrary sound field having a known pressure and known pressure gradient.

Title: Clamping-type fitting
Inventor: WILBS THOMAS
IPC: E04G7/30
Filed: 1993-06-30
Abstract: A clamping-type fitting (10) exhibits two clamping jaws (12, 14) which comprise aluminium extrudate profiles and are of different lengths. The shorter clamping jaw (14) is mounted on the other clamping jaw (12) such that it can be pivoted to a limited extent about an integrated pivot bearing (22). In said shorter clamping jaw (14) there is pivotably mounted a bolt (36) which bears a clamping bolt (16) which passes through a circumferential slot (38) in the bearing duct and can be introduced into a slot (40) at the end of the fixed clamping jaw (12). A hand wheel (44), which is supported on said clamping jaw (12) and belongs to the screw-bolt (16), needs to be screwed on only by a small number of revolutions in order to be able to pivot the clamping bolt outwardly relative to the movable clamping jaw (14), which then, for its part, pivots outwards about the pivot bearing (22) relative to the fixed clamping jaw (12), this freeing an insertion region of the clamping-type fitting (10), which region is wider than the diameter of the tube (46) to be clamped in. <IMAGE>

Title: Process for working up residues from the production of  chi -hexachlorocyclohexane
Inventor: ZEUNER FRANK DR
IPC: C07C17/25
Filed: 1993-07-24
Abstract: It is well known that the photochemical chlorination of benzene gives a technical-grade hexachlorocyclohexane mixture composed of approximately 65-70% of  alpha -HCH, 7-10% of  beta -HCH, 14-15% of chi -HCH (lindane), approximately 7% of  delta -HCH, 1-2% of  epsilon -HCH and 1-2% of other compounds. The biologically active  chi -isomer is obtained in a purity of 99.5% from this isomer mixture by extraction with methanol. Over the last decades, the residues which remain after the separation, which contain approximately 70-80% of alpha -HCH, 6-14% of  beta -HCH, 8-12% of  delta -HCH and 4-6% of epsilon -HCH, have merely been dumped in most cases. Working up these deposits is vital, in particular from an ecological point of view, the intention being to convert the biologically inactive hexachlorocyclohexane isomers into compounds which can be used as raw materials. This object is achieved according to the invention by subjecting the mixture of those hexachlorocyclohexane isomers which cannot be used as pesticides to a dehydrohalogenation process at temperatures between 50 DEG C and 150 DEG C using aqueous bases and an organic solvent in the presence of polymer-supported phase transfer catalysts, giving trichlorobenzene. The invention is used for working up residues from the production of chi -hexachlorocyclohexane, which is used widely as an insecticide against biting and sucking insects.

Title: Safety system for trains
Inventor: ADOMEIT SVEN DIPL ING
IPC: B61L25/02
Filed: 1994-02-25
Abstract: Trains communicate with actuators for the points lying ahead and set signals for them. Each actuator can only set one signal (z4f), and additional arbitrary specifications (z3f). A rail section covered by a point (w3) can only be travelled across when the signal set previously by the relevant actuator allows it. The signals are usually reset by the train as soon as it has passed the point concerned.  The advance of a train into the next section is dependent not only on the corresponding signals, but also on the train (z4) having communicated with the one still crossing the next section. Through a comparison of the positions of both trains, the following train maintains a safe distance from the train ahead.

Abstract: Un procédé permet de réduire l'imbrication de fréquences lors de la transmission de signaux audio numérisés. Il faut toujours s'attendre à une imbrication de fréquences lorsque le signal d'entrée est réparti en bandes partielles dans des étages connectés en série. Selon ce procédé, on soumet à une totalisation pondérée les signaux des bandes partielles dans lesquelles des composantes spectrales ayant des fréquences déterminées constituent des composantes des signaux, et les signaux des bandes partielles dans lesquelles ces composantes spectrales constituent des composantes d'imbrication de fréquence dans la zone d'arrêt. Après leur transmission, les signaux des bandes partielles sont soumis à une opération inverse à la totalisation pondérée. Ce procédé est indépendant du procédé de codage sélectionné et peut donc être universellement appliqué.
