Patent CA-2207690-A1 (CA)
Inventor: HOLCOMBE MICHAEL W
IPC: E21B33/16
Filed: 1997-06-12
Abstract: An apparatus and method of dropping a pumpdown plug or ball is revealed. The assembly can be integrally formed with a plug-dropping head or can be an auxiliary feature that is mounted to a plug-dropping head. The release mechanism is actuated by remote control, employing intrinsically safe circuitry. The circuitry, along with its self-contained power source, actuates a primary control member responsive to an input signal so as to allow component shifting for release of the pumpdown plug or ball. Multiple plug-dropping heads can be stacked, each responsive to a discrete release signal.     Actuation to drop the pumpdown ball or plug is accomplished even while the components are rotating or are moving longitudinally. Using the apparatus and method of the present invention, personnel do not need to climb up in the derrick to actuate manual valves. There is additionally no need for a rig floor-mounted control panel with hydraulic lines extending from the control panel to remotely located valves for plug or ball release.

Abstract: L'invention concerne un dispositif de traitement analogique (DTA) pour le traitement analogique de paquets de charges présents dans un signal analogique. Le DTA utilise des composants à base d'éléments à transfert de charge dans un dispositif semi-conducteur pour déplacer et traiter les paquets de charges présents dans un signal analogique. Dans une forme d'exécution, le DTA permet le traitement analogique de signaux dimensionnels tels que les signaux audio ou vidéo. Quand le DTA est conçu comme un dispositif semi-conducteur, il peut être réalisé comme une pastille pour un prétraitement analogique des signaux vidéo ou audio, par exemple pour la compression du signal avant la numérisation et l'utilisation par des dispositifs de traitement numérique. Dans une forme d'exécution particulière, un ensemble de DTAs avec les circuits connexes constitue un processeur de reconnaissance de motifs (PRM) à chevauchement. Le PRM peut effectuer une compression de signaux vidéo analogiques à des vitesses dépassant sensiblement les vitesses de compression possibles avec les technologies de traitement numérique actuellement disponibles.
Patent CA-2210280-A1 (CA)
Inventor: LAMMENS ARTHUR E
IPC: A47B88/00
Filed: 1997-07-11
Abstract: An interlock assembly for use with two or more vertically arranged drawers mounted on telescopic slides in a housing such as a cabinet so as to prevent the extension of a drawer once another drawer is opened. The interlocking system interfaces with the stationary members of vertically arranged slides attached to the cabinet. A pair of opposing upper and lower actuator followers are slidably and transversely fitted near the front of the stationary members so that movement of one actuator follower toward the other, displaces the other. A rod connects the upper actuator follower of one slide with the lower actuator follower of a slide directly above it. An actuator is connected to the front ends of the telescopic members of the slides. As a telescopic member is extended, the actuator of that slide makes contact and displaces the upper actuator follower of the slide which results in the upper displacement of the lower actuator followers of the slides directly above the extended slide. The extended slide also prevents the upward displacement of the upper actuator followers of all the slides directly below it. Consequently, all actuator followers block the path of their respective telescopic members precluding their extension.

Patent CA-2244555-A1 (CA)
Inventor: WANETZKY ERWIN
IPC: B03B9/06
Filed: 1998-08-05
Abstract: In a procedure to remove metal bases (4a, 4b) attached to glass bodies (6), these are brought into the effective field of an induction field coil (40a, 40b) and are heated by the electrical current induced in the bases (4a, 4b) through the induced magnetic field (42a, 42b) produced by the coils (40a, 40b). The bases (4a, 4b) heated in this way expand thermally, unlike the glass bodies (6) which are not warmed by the induced magnetic field (42a, 42b). This loosens the connection between the bases (4a, 4b) and the glass bodies (6). The loosened bases (4a, 4b) are pulled off the glass bodies (6) in the next step of the procedure, eg. with a grasping apparatus, in which no breaking pressure will be exerted upon the glass bodies (6). Thus, the bases (4a, 4b) and the glass bodies (6) may be recycled separately in procedural steps envisioned subsequently. To carry out the procedure according to the invention, an induction coil arrangement (40a, 40b) is required, in which the incandescent and flourescent bulbs (2) are transported from a readying station into the chamber receiving the induction coils (40a, 40b). A gas burner is provided to cut open the glass body (6) separated from the base (4a, 4b) and at least one ventilation hole may be burned into the glass body (6) with it.
