Patent EP-0090130-A1 (EP)
Inventor: SCHWARZ HERBERT
IPC: G07D7/00
Filed: 1983-01-18
Abstract: For checking the authenticity of security documents, in particular of tickets or the like, it is proposed that one of the two substances of a colour reaction system, consisting of an organic colour forming substance which emits electrons and a colour developing substance which receives electrons, is applied to the paper document (1) and that the surface region (5) of the paper document (1) bearing this substance is written on or printed on with a dispensing instrument (7) discharging the other substance. The substance discharged by the dispensing instrument preferably has a different colour from the reaction colour of the colour reaction system or is coloured to suit this purpose. Complementary colours are particularly suitable. Crystal violet lacton is a suitable example of a colour forming substance. Aluminium hydrate or acidic phenolic resin can be used as the colour developer. The dispensing instrument is preferably a felt pen (7) or ballpoint pen which is soaked with the liquid colour forming substance and, if appropriate, with colouring matter. It can alternatively be constructed as a printing instrument, the ribbon (29) or colour pad of which is soaked with the colour forming substance and, if appropriate, with a colour additive. <IMAGE>

Abstract: By the application of the process and equipment according to the invention flow properties of solid granular materials can be determined even while producing or processing; and by means of the intervening signals derived from measuring results, production and processing can be influenced. 
<??>Either in the mass-proportional or in the time-proportional mode of operation, changing one of the parameters in each cycle, the sample-medium is allowed to pass through the sample-holder (101) and using the mass-signal and period-signal thus obtained partly the signal of mass-flow, partly the signal of the density of mass-flow is generated, and from said signals - based on the recognized new correlation - any of the parameters characterizing the technological process is generated by signal processing. 
<??>The equipment is provided with a sample-holder (101) with changeable geometry, to the corresponding points of which a type-signal transmitter (102) and an aperture-signal transmitter (103) are connected.

Abstract: A voltage-control type semiconductor switching device (Q1) is disclosed which includes a pair of control electrodes (20, 22) to which a control voltage signal is supplied, and a semiconductive layer (10) formed between the electrodes (20, 22) so as electrically insulative from the electrodes (20, 22) through insulative layers (16, 18). The semiconductive layer (10) has a channel region (10a) and a carrier-storage region (10b) which is substantially nonconductive. The channel region (10a) is formed laterally along the longitudinal direction (y) of the electrodes (20, 22), thereby allowing majority carriers such as electrons of the semiconductive layer (10) to flow in the lateral direction (y). In the current cut-off mode, the carrier-storage region (10b) temporarily stores the carriers which move in the direction (x) of thickness of the semiconductive layer (10) due to the electric field created by the voltage. In the current conduction mode, the carrier-storage region (10b) releases the carriers stored therein toward the channel region (10a).

Abstract: Un système de télémétrie permettant de détecter des évènements physiques éloignés et de transmettre et d'amplifier des signaux de données numériques représentant les évènements détectés au travers d'une ligne de transmission (22), comprend une horloge principale (24, 26) et une pluralité de postes de détection (20) permettant de détecter les données locales. Les postes de détection (20) injectent des données locales dans la ligne de transmission (22) sous forme de signaux de données numériques, et un contrôleur/récepteur (28) reçoit les données numériques. L'horloge principale (24, 26) initialise la synchronisation du système et produit un signal de synchronisation. Chaque poste de détection (20) comprend un sous-système amplificateur (40) recevant les données numériques locales et injectant ces données numériques dans la ligne de transmission (22) sous forme de signaux de données numériques. Pendant le démarrage du système, chaque sous-système amplificateur (40) réclame une tranche de temps, par rapport à un procédé d'organisation, pour injecter les signaux de données numériques dans la ligne de transmission (22). Le sous-système amplificateur (40) dans chaque poste de détection (20) comprend en outre un circuit amplificateur (60) permettant d'amplifier les signaux de données numériques se propageant dans la ligne de transmission (22), ainsi que les signaux de synchronisation. Le circuit amplificateur (60) comprend un dispositif bistable à impédance négative qui améliore l'amplitude et le temps de montée des signaux de données numériques. Chaque sous-système amplificateur (40) comprend en outre un circuit de régulation de mode de commutation (56) permettant de convertir un courant d'alimentation dans la ligne de transmission (22) en une tension de niveau constant, alimentant ainsi en courant local les composants du poste de détection (20).

Abstract: Procédé et dispositif permettant à une pompe située au fond d'un puits de forage pétrolier, effectuant un mouvement alternatif, mue par une source de fluide sous pression s'écoulant au traversd'une installation de conduite (32), de pomper du liquide du puits au travers d'une autre installation de conduite (30). La pompe de fond possède des organes internes servant à mettre à l'évent les gaz et les vapeurs provenant de la chambre de pompe (52) et de produire une course de la pompe uniquement lorsque la chambre de pompe se remplit de liquides. On détecte le remplissage de la chambre de pompe grâce à un limiteur d'écoulement sensible à l'écoulement (184) qui contrôle la mise à l'évent du gaz et des vapeurs et provoque la fermeture de l'évent lorsque le liquide s'écoule par le limiteur, fermant ainsi une soupape mécanique (150) pour permettre l'écoulement du fluide de travail vers le piston de la pompe (74). Le piston présente une tête en forme de dôme (80) et le cylindre possède des lumières (62) permettant l'expulsion des sédiments de la chambre de pompe. La vitesse de la course de la pompe peut être réglée indépendamment en ajustant la sortie de la source de fluide sous pression et la course de retour peut être réglée par un dimensionnement convenable des lumières pour l'écoulement de retour.

Abstract: An electromagnetic relay for use in a high-frequency circuit includes an armature (3) mounted on a central shaft (16) for pivotal movement between two switching positions. A total of four actuator cards (5) are disposed on two opposite sides of the armature (3) each card carrying a contact spring (8). Each contact spring serves to bridge a pair of fixed contacts (6, 7). The contact springs and fixed contacts are located in shield casings (9) disposed on both sides of the armature (3). Return springs (19) urge the cards (5) into abutment with the respective sides of the armature (3). Sufficient electrical separation as required for high-frequency applications is achieved between the two contact systems due to the intermediate disposition of the armature (3). The provision of an individual actuator card (5) for each contact spring (8) permits independent adjustment of each contact.

Abstract: The invention relates to an apparatus for singling and orienting coiled tension springs which have hook-like bends at, at least one end of the spring. The apparatus uses a guide through which the springs are fed to a receiver. The receiver has a chamber and the chamber has an inlet opening for the introduction of the spring into the chamber of the receiver. The receiver can swing about an axis that is transverse of the axis of the guide from a first position in which the inlet opening of the chamber is in line with the guide and the chamber of the receiver forms the prolongation of the guide to a second position in which the inlet opening of the chamber is out of line with the guide. A sword-like element moves into and out of the chamber in a direction transverse to the chamber.
