Abstract:
Systems and methods for magnetically autonomously clamping a downhole component in a select direction of a borehole casing. The systems can include a sensor package that obtains a downhole measurement in a position in a cased borehole. The systems can include an integral magnetic clamp that removably clamps the downhole component (e.g., a downhole seismic shuttle) to the cased borehole. The systems can include a directional detector that outputs a select direction of the cased borehole relative to the downhole component. The systems can include a downhole controller that activates a portion of the integral magnetic clamp of the downhole component closest to the select direction output by the directional detector.
Abstract:
An impingement plate atomizer apparatus includes an electrostatically charged longitudinal member having an upper surface sized and shaped to receive a liquid cryogen thereon, a lower surface opposite to the upper surface, and at least one hole extending through the longitudinal member; an ultrasonic transducer in contact with the longitudinal member for providing ultrasonic energy thereto for atomizing the liquid cryogen into an electrostatically charged cryogen fog. A method is also provided for providing an eiectrostaticaily charged cryogen fog.
Abstract:
The present invention relates to an apparatus and method for coating a substrate (15) using one or more liquid raw materials, comprising: at least one atomizer (2) for atomizing the one or more liquid raw materials into droplets (3), charging means (4; 32) for electrically charging the droplets (3) during or after the atomization and a deposition chamber (16) in which the droplets (3) are deposited on the substrate (15), the deposition chamber (16) being provided with one or more electric fields for guiding the electrically charged droplets (3) on th e substrate (15). According to the invention there is a charging chamber (1) arranged upstream of the deposition chamber (16) and provided with charging means (4) for electrically charging the droplets (3).
Abstract:
Die Erfindung betrifft eine Elektrodenanordnung für einen elektrostatischen Zerstäuber, insbesondere für einen Rotationszerstäuber, mit einer Elektrodenhalterungseinrichtung (101) zur Halterung zumindest einer ein elektrostatisches Feld erzeugenden Elektrode (108) um eine Symmetrieachse (105), wobei ein dielektrisches Material zur Beeinflussung einer sich in Richtung der Symmetrieachse erstreckenden Entladungsstromkomponente vorgesehen ist.
Abstract:
A process of organic coating of components (10) such as casings of hard discdrives. The process includes the steps of supporting the casing on a first tray (20) and supporting a number of the first trays with the casing supported thereon in an array on a second tray (30). The component, the first tray and the second tray are electrically conductive so that electrically grounding the second tray electrically grounds the component. The array is then electrostatically coated (40) with a water based organic coating material and then transported to a flash off oven (50) and then transported to a curing oven (60).
Abstract:
An apparatus for and method of coating an article by the use of electro-static attraction of ionized particles which are subsequently cured. The apparatus includes a first foraminous conveyor for carrying the article through a powder coating zone and a second conveyor for carrying the article through a curing zone. The surface of the article which rests on the foraminous conveyor is cleaned of particles as the article is tranferred from the first foraminous conveyor to the second conveyor. The first foraminous conveyor is also cleaned of particles after the article has been transferred. After the articles have been cured to form a coating on the article, the article is put through the coating system again except that the article is supported on the conveyor so that the surface which was not coated in the first pass through the system is out of contact with the conveyor. During the subsequent pass of the article through the coating zone, the uncoated surface of the article is then covered with powder which is subsequently cured during the second pass of the article through the curing zone.The second coating step for the article may be accomplished by passing the article through the same apparatus as for the first step or by passing the article through a second identical apparatus.
Abstract:
A pan oiler for depositing cooking oil into product molds of a baking pan includes a conveyor assembly configured to carry the baking pan through the pan oiler and an electrostatic oiler assembly. The electrostatic oiler assembly includes at least one injector assembly, a charge assembly and an oil delivery assembly. The injector assembly may include a valve body, an oil reservoir within the valve body, a valve seat within the valve body in fluid communication with the oil reservoir, a plunger extending into the valve body and an actuator operably connected to the plunger to lift the plunger off the valve seat when the actuator is energized. The plunger is retractable and conductive and in electrical contact with the charge assembly.
Abstract:
Cette méthode permet l'application d'un produit de revêtement sur une pièce (13) déplacée par un convoyeur (12), le long duquel est disposé au moins un pulvérisateur (62.1, 62.2). Elle comprend des étapes automatisées consistant à déterminer dans un repère fixe (X12, Y12, Z12), les coordonnées des points (A1, B1, C1, A2, B2, C2) d'une ou plusieurs lignes (L1, L2) de profil extérieur de la pièce réparties sur la longueur de la pièce, à attribuer à chaque pulvérisateur les points de chaque ligne de profil extérieur qui se trouvent dans son champ de pulvérisation, à identifier, parmi les points attribués à chaque pulvérisateur, le point le plus proche (A1, A2; B1, B2) du pulvérisateur pour chaque ligne de profil extérieur, à déterminer pour chaque pulvérisateur, une ligne de suivi (L3, L4) passant par tous les points les plus proches (A1, A2, B1, B2) du pulvérisateur identifiés à l'étape c), et à établir une trajectoire de consigne pour chaque pulvérisateur en fonction des points de la ligne de suivi (L3, L4) de manière à ajuster automatiquement et indépendamment la distance d'application de chaque pulvérisateur en fonction du profil extérieur de la pièce.
