Patent DE-4333358-A1 (DE)
Inventor: MEYER DIETER ING GRAD
IPC: H04B3/54
Filed: 1993-09-30
Abstract: The arrangement uses, for the purposes of coding and transmitting information on a two-wire line 4 between a transmitter 1 and a receiver 5, direct voltage or current pulses which contain the information in the period or frequency. This is achieved in that the transmitter 1 switches the operating voltage for the receiver 5 off briefly means of a semiconductor switch 3. Digital to analogue conversion and vice versa are no longer necessary. Furthermore, a high make-to-break ratio is employed so that the supply to the receiver is always ensured, and receiver 5 includes a voltage stabilisation device 6, decoder 8 and indicator 7. <IMAGE>

Title: Sliding repair system for surfaces and round bodies
Inventor: SCHMIDT ERICH
IPC: E04G23/02
Filed: 1993-11-06
Abstract: In order to repair structures, in particular by filling any arising cracks and broken-out sections, use is made of a device which comprises a panel-like formwork which exhibits, on the side facing the structure, an inflatable body which can be laid in the crack. Said inflatable body is integrated in the crack with air such that sealing takes place, with the result that the panel-like formwork takes over the additional securement. Through the inflatable body, via a filling valve, a material comprising one or more components is pressed into the crack, with the result that effective interlocking is achieved. After relieving of the inflatable body, the panel-like formwork can be removed and a uniform surface can then be produced, the corresponding plaster also reaching part of the way into the crack. <IMAGE>

Patent DE-4415846-A1 (DE)
Inventor: ROCHE MICHEL PROF
IPC: B01J2/20
Filed: 1994-05-05
Abstract: The invention pertains to a device used to manufacture pastilles or pellets by shearing a stream of an extruded mass subject to forces of inertia. The invention consists of a curved tube (2) in which the mass is circulated and which is provided with numerous drilled holes (3) which are situated along a generatrix and through which the mass is expelled at high speed. The tube is forcefully moved (agitated) in order periodically to divide the extruded stream into pieces and in this way break off "drops", which can then be cooled on a flat surface to form pastilles or shaped in free fall into a spherical granulate. An advantageous design involves a percussive device, where the movement is sustained by piezoelectric ceramics: the tube alternately strikes against two rows of metal stops (5) which are reinforced with piezoelectric ceramics (11) and thus impart to the tube the energy lost at the moment of impact and as a result of friction. The device is primarily suited for the pharmaceutical, chemical and agricultural feed industries.

Title: Method for the production of a sliding bearing
Inventor: RUMPF THOMAS DR
IPC: F16C33/12
Filed: 1994-12-14
Abstract: A description is given of a method for the production of a sliding bearing with a steel supporting shell, a bearing-metal layer and a copper-containing sliding layer electrodeposited on the bearing-metal layer. In this method, the supporting shell is coated with a tin-containing anticorrosion layer on the rear side forming the back of the bearing after the application of the sliding layer. In order to prevent detachment of the corrosion layer, it is proposed that the back of the bearing should be coated in a manner known per se with an electrodeposited layer of nickel before the application of the sliding layer to the bearing-metal layer.

Title: Procede et dispositif permettant de remettre en forme des paires de signaux
Inventor: BEHRENT HERMANN
IPC: H03D3/00
Filed: 1995-08-24
Abstract: L'invention concerne un procédé et un dispositif permettant de remettre en forme des paires de signaux orthogonaux. Des distorsions linéaires interviennent lors du traitement de paires de signaux I et Q orthogonaux dans des émetteurs et des récepteurs. Ces distorsions linéaires constituent essentiellement le décalage de la composante continue, ainsi que la différence d'amplitude et le déphasage entre la branche I et la branche Q, ou ellipticité. Des circuits de correction classiques ne régulent les distorsions linéaires que de manière incomplète, à l'aide de boucles d'asservissement rétroactives. Les procédés numériques classiques présentent l'inconvénient d'induire des erreurs d'arrondi importantes et de requérir des calculs complexes. Afin de remédier à ce double inconvénient, il est prévu de corriger le décalage de la composante continue et de l'ellipticité séparément, à l'aide de calculs de compensation, au moyen d'une matrice 3 x 3 spéciale. Les calculs complexes se trouvent considérablement réduits dans la mesure où dans un premier temps, le décalage de la composante continue, puis ensuite l'ellipticité sont éliminés. Ce procédé s'utilise par exemple dans les récepteurs homodynes et le dispositif correspondant est facile à produire et économique à mettre en ÷uvre.
