Filed: 1989-06-12
Abstract: The radar sonde is installed in a wall behind a urinal (1) and oriented obliquely upwards at an angle ( alpha ). The radar sonde has a horn antenna which detects persons moving in the field (6) and identifies the direction of such movement. Flushing of the urinal (1) is triggered when a movement away has been recorded following a movement towards the urinal. Flushing is also triggered when a new user approaches the urinal during the flushing time. <IMAGE>

Abstract: A locking device, especially for a cover (11) of a suction cleaner, comprises at least one movable latch (12) cooperating with a corresponding step (13) on the cover. The latch is attached to the free end of a leaf spring (14). A control means (17) is provided adjacent the leaf spring and movable in parallel therewith. The control means has a push button (17a) at one end and an inclined guide sur­face (17b) at its other end, said guide surface cooperating with a corresponding stationary supporting surface (18). Axial displacement of the control means (17) by means of the push button (17a) results in a lateral movement which actuates the leaf spring (14) to release the latch (12) from its engagement with the step (13).

Abstract: Un système de tension et de rappel (28) établit et maintient une force sensiblement constante sur un galet-tendeur (18) d'un ensemble chenille sans fin (20) pour un véhicule chenillé (10). La force appliquée sur le galet-tendeur (18) met en tension la chenille sans fin (24) et maintient une force de friction prédéterminée entre la chenille (24) et une roue d'entraînement motorisée (16). Le système (28) assure également une fonction de rappel du galet-tendeur (18) lors de la pénétration de corps étrangers entre la chenille (24), le galet et la roue d'entraînement (16, 18). Le système de tension et de rappel (28) comporte un élément tubulaire de rappel (50) qui s'insère dans un cylindre (36) et une seule chambre (56) hermétiquement fermée et remplie d'un gaz compressible. Ce système de tension et de rappel diffère des systèmes de rappel classiques en ce qu'il (28) comporte un ressort à gaz compressible à la place du ressort d'acier à gros boudins de la technique antérieure, d'où un encombrement et un poids moindres, ainsi qu'un montage et un démontage simplifiés.

Abstract: Lors du fonctionnement d'un moteur diesel polycylindrique à faible vitesse de rotation, il est calculé une première valeur moyenne de vitesse n(Boolean not), mesurée sur presque un cycle moteur complet, et une seconde valeur moyenne nalpha, la valeur nalpha n'étant calculée que sur une plage de vitesse angulaire correspondant à la distance entre deux points morts hauts. Cette plage de vitesse angulaire est pré-décalée, par rapport au point mort haut, d'un angle dépendant de la vitesse de rotation. La variation de vitesse n* - n(Boolean not) est régulée par un régulateur lent, et la variation de vitesse n*-nalpha est régulée par un régulateur rapide. Les deux régulateurs agissent sur le remplissage des cylindres. Le régulateur lent n'accomplit que de faibles modifications du degré de remplissage, le régulateur rapide permet une intervention rapide lors de perturbations.

Abstract: Système permettant l'étalonnage et la commande de réaction à boucle fermée de signaux d'image provenant de dispositifs d'image à couplage de charge (CCLID). Pendant l'étalonnage périodique par itération, l'échantillonnage des signaux de sortie de cellules de référence sombres sur un dispositif à couplage de charge (CCD) (16) produit un niveau (noir) de tension en courant continu de remise à l'état initial. Une bande blanche de référence (28) est lue avant que le gain du système (26) ne soit ajusté. Le procédé se poursuit jusqu'à ce que les valeurs lues soient égales aux valeurs attendues. Le procédé d'étalonnage s'achève donc et la valeur différentielle est fixée pour la lecture ultérieure. Au cours de la lecture normale, les signaux de niveau blanc et de niveau noir de chaque ligne de lecture sont ajustés pour permettre au système de fonctionner dans une plage dynamique complète. Les cellules sombres sont échantillonnées et produisent une tension qui est modifiée par la tension différentielle fixée au cours de l'étalonnage. La bande blanche de référence est à nouveau lue et le gain du système ajusté.

Abstract: An event-controlled method for mixed-mode simulation of electronic circuits and systems is specified. The use of a special wave form relaxation algorithm provides for the simultaneous event-controlled simulation of digital and analog circuit sections at different circuit description levels. During the simulation, event lists are generated and administered for controlling the simulation process. The interfaces between digital and analog circuit sections are matched by means of coupling elements which effect the signal transformation between analog and digital signal functions. The method can be used for simulating complex electronic circuits, in which different circuit sections are described at different circuit description levels and are simulated at different simulation levels, in an extremely efficient manner in accordance with the principle of event control.

Abstract: Process and apparatus for the removal of patterning material selectively applied to a screen printing stencil according to a pattern, in which a medium is sprayed at high pressure locally against the stencil and the stencil is moved in such a way relative to the spraying point that the entire part of the stencil coated by patterning material is covered. The medium can be water of which the pressure lies in a range between 150 and 300 bar. Preferably the spraying is always carried out oppositely from both sides of the stencil. Further the spraying may take place in a pulsating manner and prior to spraying the stencil may be treated with a weakening medium which weakens the bond between the patterning material and the stencil, while essentially maintaining the bond.

Abstract: The invention provides a dispensing composition for the controlled release of semiochemicals, such as pheromones, wherein the semiochemical is enclosed in a network of a crosslinked polymer which is substantially free of radical initiator residues. The dispensing composition can be prepared by mixing a prepolymer with the semiochemical and optional additives and crosslinking the mixture by means of gamma radiation or electron beam treatment, or by UV radiation or heat in the presence of a radical initiator, the residues of which are subsequently extracted. The prepolymer is preferably an acrylate or methacrylate terminated prepolymer. The rate of release of the semiochemical can be varied by modifying the network density, the type of prepolymers, the degree of loading and the shape of the dispenser. Vulnerable semiochemicals can be stabilized by adding stabilizers, such as UV absorbers and antioxidants. The predetermined release rate can be sustained for several months. The composition can be shaped or applied as a coating.

Abstract: In known photographic processing apparatus, quality of the photographs produced can be adversely affected by drift in the paper processor of the apparatus. One cause of drift is incorrect replenishment of the chemicals used in the paper processor. In processing apparatus which utilise only small volumes of chemicals, drift can be caused by replenishment rates not matching the dye formed on the prints being processed, and an operator would need to take steps to adjust the processor. Described herein is an improved method of controlling the replenishment rate of chemicals in photographic processing apparatus. The method comprises deriving a control signal from the image to be exposed on to photographic material and using the derived signal to control the replenishment rate of the chemicals.
