Title: Electromagnetic switching apparatus for controlling electric-motor drives whose rotation direction is reversible
Inventor: DIETRICH BERNHARD ING GRAD
IPC: H01H50/54
Filed: 1982-08-17
Abstract: An electromagnetic switching apparatus for controlling electric-motor drives whose rotation direction is reversible comprises a stationary contact support for a number of stationary contacts arranged opposite one another in two rows, in contact levels, and a slide, which is supported in the stationary contact support and carries contact links which are supported resiliently. Until now, two such switching apparatuses have been required for controlling an electric-motor drive whose rotation direction is reversible. In order to save the second switching apparatus, the new switching apparatus contains a slide with two contact-making end positions and a central position in which all the contacts are opened. Each contact link consists of two parallel individual links, between which a helical compression spring is located, and one of which makes contact in the one limit position and the other in the other limit position. Furthermore, only a single external wire link is now necessary if two contact levels are isolated from one another by an empty level in which a stationary contact is arranged which has two contact points, one of which extends into the one adjacent contact level and the other of which extends into the other adjacent contact level, and can be connected to the opposite stationary contact of the relevant contact level by the associated individual link.

Title: Process for the preparation of salts of phenylhydrazine- beta -carboxylic acid
Inventor: HUPFER HEINZ DR
IPC: C07C281/02
Filed: 1982-12-16
Abstract: Phenylhydrazine reacts with hydrocarbonates of the alkali metal group and of ammonia in aqueous solution at room temperature to give the corresponding salts of phenylhydrazine- beta -carboxylic acid. From these salts, phenylhydrazine can be liberated again by the action of alkali metal hydroxide solutions at increased temperature. The salts of phenylhydrazine- beta -carboxylic acid, which have been obtained by the above method, form water-soluble complexes with more phenylhydrazine and can therefore be used as solubilisers for phenylhydrazine.

Title: Circuit arrangement for measuring mechanical displacements
Inventor: NABETA EIICHI DIPL ING
IPC: G01D5/241
Filed: 1984-03-06
Abstract: A circuit arrangement for measuring mechanical displacements contains a capacitive sensor having two measuring capacitors (CA and CB) as well as a differential amplifier arrangement (4) for generating a voltage corresponding to the difference between the capacitances of the two measuring capacitors (CA and CB). In order to obtain a particularly high measurement accuracy, a controllable device (1) for charging and discharging the measuring capacitors (CA and CB) is connected to the capacitive sensor; a threshold detector (2) alternately monitors the voltages at the measuring capacitors (CA and CB) for overshoot of a prescribed threshold value and controls a bistable flip flop (Q2) which, for its part, controls a device (3) for alternately charging and discharging a first and second auxiliary capacitor (C1 and C2). It is possible with the aid of a delay element (Q3) downstream of the threshold detector (3) to delay discharging of the first or second auxiliary capacitor (C1 or C2) in such a way that the output voltage of the differential amplifier arrangement (4) is, independently of the stray capacitances of the measuring capacitors (CA and CB), proportional to the mechanical displacement detected by the capacitive sensor (Fig. 2). <IMAGE>

Title: Flat display device for alphanumeric and graphic information as well as television images, and a method for operating this display device
Inventor: NISCH WILFRIED DIPL PHYS
IPC: H01J31/12
Filed: 1984-09-07
Abstract: The invention relates to a display device based on MIM (metal-insulator-metal) thin-film cathodes as electron sources, having a post-deflection acceleration space and having a fluorescent screen in a flat, gas-tight evacuated sleeve. The thin-film cathodes are arranged in rows and columns to form a matrix. By reducing the electron work function of the thin-film cathodes by means of a sub-atomic thin film consisting of an electro-positive adsorbate, such as oxidised Cs, the electron scatter in the covering metal of the cathodes can be reduced. The emission flow densities of the thin-film cathodes required for an adequate luminous intensity, of at least 1 mA/cm<2> are then achieved even at cathode voltages (drive voltages) of less than 5 V (TTL level). By metallising the fluorescent substance with an aluminium coating which is semi-permeable for electrons, the breakdown strength and hence the pixel clarity and the operating reliability of the display are increased. For colour reproduction, the number of cathodes in the rows or columns is increased by a factor of three, and a correspondingly constructed fluorescent screen is provided. The control voltages in the case of images which are written in raster form are applied simultaneously with the aid of a buffer store (TTL or MOS) for all the individual cathode rows, and each pixel is hence driven over the full term duration in order thus to increase the electron-optical efficiency.
