Abstract: A dual band multimode coaxial antenna feed has an inner section of longitudinal hollow waveguide having first and second orthogonal mode transducers that interface first and second orthogonally polarized cylindrical waveguide TE11 mode signals lying in a first upper (e.g.,Ka) frequency band.  An outer coaxial waveguide section has a Potter horn surrounding the inner waveguide section, which terminates at a polyrod. The outer section includes third and fourth orthogonal mode transducers that interface orthogonally polarized coaxial waveguide TE11 mode signals lying in a second lower (e.g.,X) frequency band. A tracking port coupled to the outer coaxial waveguide section provides an output representative of the difference pattern of the radiation profile produced by transverse electromagnetic TEM mode signals generated and propagating in the outer coaxial waveguide. A mode supressor in the outer waveguide section adjacent its two orthogonal mode transducers locally supresses TEM signals in their vicinity.

Abstract: Une sonde qui permet de détecter le mouvement d'un corps magnétique comprend une pièce polaire magnétisable, un circuit électrique en boucle fermée présentant une première extrémité enroulée autour de la pièce polaire et formant un enroulement couplé par induction à la pièce polaire. Ce montage fait que le mouvement d'un corps magnétique par rapport à la pièce polaire induit un courant dans le circuit en boucle fermée et d'une seconde extrémité, éloignée de la pièce polaire, qui forme un enroulement primaire de transformateur. Un enroulement secondaire de transformateur est inductivement couplé à l'enroulement primaire et se termine par une résistance de charge et des moyens permettant de mesurer le signal de sortie du bobinage secondaire. Les enroulements primaire et secondaire forment un transformateur, de sorte qu'un courant dans l'enroulement primaire induit une tension aux bornes de l'enroulement secondaire. Une ou plusieurs spires de mise en court-circuit d'un conducteur sont inductivement couplées aux enroulements primaire et secondaire.

Granted: 2009-02-10
Abstract: A drive mechanism for an agricultural planter includes a first electronic controller, a second electronic controller, a hydraulic valve manifold, hydraulic drives for the seed and fertilizer hoppers, and a feedback sensor from the hydraulic drives to the second electronic controller. The first electronic controller is located in the cab of the tractor connected to the planter, while the second electronic controller is mounted on the planter to control the operation of the hydraulic drives. The feedback sensors provide data as to the operation of the hydraulic drives. Another sensor associated with the forward speed of the planter also provides input to the second electronic controller so that the second controller can coordinate the operational speed of the hydraulic drives to provide the rate of application of the seed and fertilizer products desired by the operator. Changes in the rate of application of either the seed or fertilizer materials can be accomplished through input to the first electronic controller.

Granted: 2012-05-01
Abstract: A description is given of a method for the analysis and/or monitoring of the partial discharge behavior of an electrical operating means, in particular in terms of its development over time. Here, appropriate partial discharge data is recorded in process state matrices (2, 3), in which, in each case in a matrix element (5) of the process state matrix (1), the amplitude (7) of a partial discharge, its phase angle (6) and its frequency of occurrence is depicted (in particular what is known as a PRPD representation). A simplified analysis is made possible by the fact that, at a first time, a partial discharge process state is registered in a first process state matrix (2) and, at a later time, a further partial discharge process state is registered in a further process state matrix (3). Then, for the purpose of analysis and/or monitoring, the first (2) and the second (3) process state matrix are compared with the aid of comparison and scaling methods.

Abstract: The present invention provides a switching apparatus having a design intended to reduce wear on its key part. In an embodiment of the invention, a rotatable member is rotatably fixed on a pivot. A slidable bearing member has a first surface for engaging the rotatable member in a non-sliding manner, and an opposite second surface for slidingly engaging an abutment. Any significant wear on the switching apparatus is more likely to occur between the sliding member and the abutment, rather than between the rotatable member and the sliding member. In an embodiment, one of the rotatable member and the slidable bearing member includes a protuberance, and the other of the rotatable member and the slidable bearing member includes a corresponding indentation for engagement with the protuberance. The join formed between the protuberance and indentation provides a substantially non-sliding engagement between the rotatable member and the slidable bearing member.

Abstract: L'objectif de cette invention est de limiter la durée d'utilisation d'un appareil pour des raisons hygiéniques, médicales ou techniques. A cet effet, un dispositif ne pouvant pas être influencé par l'utilisateur de cet appareil est nécessaire, lequel dispositif empêche la réutilisation dudit appareil de façon fiable, efficace et définitive, dès que le nombre prescrit de manoeuvres est atteint. Selon cette invention, un mécanisme tendeur à blocage pourvu d'une sortie à ressort et d'un compteur, équipant un appareil de ce type et inséré dans un boîtier en deux parties montées de façon à pouvoir pivoter l'une par rapport à l'autre, peut être bloqué par un ressort à lames précontraint. Ce ressort à lames est d'abord inséré dans un évidement formé dans la paroi de la première partie du boîtier. Dès que le nombre admissible de manoeuvres est atteint, un taquet pousse le ressort à lames de façon le faire sortir de sa position de repos. Ce ressort à lames s'engage dans un évidement formé dans la paroi de l'autre partie de boîtier, de sorte que les deux parties du boîtier ne peuvent plus être pivotées l'une par rapport à l'autre. Ce taquet peut être installé dans l'aiguille du compteur. Ce dispositif de blocage ne peut être libéré que par l'application d'un moment de force avec lequel l'appareil est détruit. Ce dispositif de blocage s'utilise pour bloquer un pulvérisateur haute pression ou un injecteur sans aiguille permettant de pulvériser un liquide sous la forme d'un aérosol ou d'injecter un liquide dans un tissu biologique.
