Patent EP-0430126-A1 (EP)
Inventor: DARMON MARC
IPC: H04L1/18
Filed: 1990-11-26
Abstract: Method and device for digital information transmission, with automatic retransmission request should the message be poorly received. There is provision, in the transmitted frame, for sufficient room to be able to receive several (n) useful information blocks, so as to reabsorb an excessive delay of (r) due to the successive retransmissions. The decoder (2) provides the management microprocessor (5) with a confidence indicator (3). The Control block (COM) which leaves this decoder possesses an indicator (C) of the number of useful blocks transmitted in the frame. It is advantageously directed (6, 9) towards an HDLC component (8). <IMAGE>

Abstract: The apparatus comprises a transmitting electrode (1) producing a magnetic field near the material to be tested and a receiving electrode (2) receiving the magnetic field. A frequency-wobulated voltage is applied to the transmitting electrode and a circuit measures the voltage at the terminals of the second electrode. So that the electrodes may be applied to the same side of the material to be tested (the material whose surface impedance is to be measured), the electrodes (1, 2) are superimposed with an intermediate dielectric block (3), thus forming a compact probe (SM). Measurements of the impedance are then independent of the dimensions and geometry of the material.

Filed: 1990-10-03
Abstract: Le dispositif décrit, qui sert à assurer la commande par modulation d'impulsions en largeur (commande PWM) d'un moteur de chariot (1) d'une imprimante, comprend un circuit (65) générateur d'un premier groupe d'impulsions PWM ayant un rapport cyclique de 100 %, des circuits (31, 37, 39, 15, 17, 53, 57, 59) qui calculent un second groupe d'impulsions PWM par un procédé de régulation PI (proportionnelle et intégrale) sur la base de l'écart entre une vitesse effective du moteur et une vitesse de référence, ainsi qu'un circuit (121) qui maintient une valeur d'intégration optimale de façon à amener la vitesse effective à correspondre avec la vitesse de référence. Le moteur du chariot est accéléré avec une accélération maximale en fonction du second groupe d'impulsions PWM, jusqu'à ce que la vitesse effective du moteur du chariot atteigne une vitesse de commutation prédéterminée qui est légèrement inférieure à la vitesse de référence. Après que la vitesse de commutation a été atteinte, une valeur d'intégration optimale est établie en tant que valeur d'intégration initiale sur la valeur d'intégration de l'opération de régulation PI et, ensuite, la vitesse est régulée par le procédé de régulation PI. La commande PWM fonctionne de sorte que le courant alimentant le moteur du chariot ne dépasse pas une valeur limite de courant qui a été déterminée préalablement en fonction de la vitesse de référence. La période de référence PWM peut être modifiée arbitrairement.

Filed: 1991-01-24
Abstract: Method and equipment for carrying it out for transferring, in particular, triple-axle semitrailers of semitrailer trucks from the road to low-loader railway wagons at the same level are described. The invention is characterised by the fact that both safety devices for the correct positioning and securing of the vehicles on the low-loader wagons and safety wagons which prevent the vehicles breaking out laterally during travelling are provided. The safety devices for correct positioning and locking of the vehicles on the low-loader wagon permit a rapid transmission of technical signalling information and monitoring of the correct securing of the positioned vehicles to the authorities railway. When stop blocks are used to lock the vehicles, mechanical contacts (0582d, 0592c) are actuated when they are applied and tightened, which blocks are part of a digital signal transmission circuit which operates e.g. via radio and transmits to the train control signals relating to the correctly applied and functioning safety devices (stop blocks) either directly or via intermediate points provided on the individual wagons. The safety devices which prevent the lateral breaking out of the vehicles are composed of folding walls (043) along the longitudinal sides of the low-loader wagons, which in the folded-together position permit the transfer from the road to the low-loader wagon or vice versa and which in the unfolded position prevent the lateral breaking out of vehicles which for example have become released. In all the devices for carrying out the devised method special value was placed on the fact that the dimensions of said devices always remain within the standard limits for rail vehicles. <IMAGE>

Abstract: A quick connect/disconnect coupling for dental handpieces that includes a pair of telescoping coupling sleeves equipped with a plurality of bayonet slots and lugs for detachably connecting the sleeves together. In one sleeve is a spring-loaded connector body having a plurality of axially extending passages communicating with the fluid (air and water) conduits of a supply hose, the connector having a hard-surface planar end face exposed at the distal end of the sleeve. The other sleeve is a proximal extension of a handpiece and contains a plurality of tubes arranged and dimensioned to be received in the passages of the connector body when the two sleeves are coupled together. A resilient gasket, confined by a rigid support ring, surrounds the tubes and includes frusto-conical ring portions about such tubes for sealingly engaging the end face of the connector body. When the sleeves are coupled together, the spring-loaded connector body is axially displaced so that the force of the spring maintains the body and gasket in sealing contact under a predetermined and reproducible compressive load.

Abstract: The present invention relates to novel receptor polypeptides, which, upon interaction with certain ligands, or activation by certain compounds, modulate transcription of certain genes by binding to cognate response elements associated with promoters of such genes. The novel receptors of the invention modulate transcription in the presence of retinoid compounds. The receptors of the present invention differ significantly from known retinoid acid receptors, in protein primar yseqence and in responsiveness to exposure to various retinoids. The invention provides DNAs encoding the novel receptors, expression vectors for expression of the receptors, cells transformed with such expression vectors, cells co-transformed with such expression vectors and with reporter vectors to monitor modulation of transcription by the receptors, and methods of using such co-transformed cells in screening for compounds which are capable, directly or indirectly, of activating the receptors. The invention also provides nucleic acid probes for identifying DNAs which encode additional retinoid receptors of the same class as the novel receptors disclosed herein.
