Title: Doorstop
Inventor: WIGLEY CHARLES L SR
IPC: E05C19/18
Filed: 1993-09-07
Abstract: A doorstop including an elongated shaft slidably and rotatably received within a receptacle seated in a floor proximal a door.  The shaft extends vertically from the receptacle and has a cross-member integrally connected thereto and extending therefrom in opposing lateral directions such that the door, when opened toward the shaft, will contact the cross-member and rotate the cross-member into planar contact with the door.  Thus, the movement of the door will be limited by the shaft and laterally extending  cross-member.    In a separate embodiment, end portions are integrally connected to the cross-member which project generally horizontally therefrom.  When the end portions are facing or protruding toward the door, movement of the door from its closed position is completely obstructed.  This embodiment functions as the original embodiment described above when the end portions are facing away from the door.    A rigid plate may be connected to the door to protect the door from damage from the cross-member and shaft and, further, to distribute the force placed on the door over a larger surface area thereof.

Abstract: An isolator surge protector for use with corrosion protection systems which are an inherent part of or coupled to an electrical power system, for power transformers, and for DC transmission systems, where it is necessary to present a high impedance to DC and a low impedance to AC up to a predetermined voltage level. Anti-paralleled thyristors in the isolator surge protector turn on during power surges. A bypass circuit insures turn off of the thyristors after a triggering event such as lightning or a 60 Hz surge has ended. The bypass circuit shunts DC bias currents, such as that which may be provided by a DC bias voltage source for cathodic protection, from the thyristors to ensure that the voltage across each thyristor falls below its holding voltage or current, and thus prevents the thyristor from being stuck in a continuous conduction mode. Power to operate the bypass circuit may be tapped from the surge which caused the thyristor to trigger so that the bypass circuit operates autonomously. The circuit may also operate with an auxiliary power supply to provide the required operating power and to turn off the thyristors.

Abstract: An improved tubing rotator is mounted to the casing bowl of a well, for rotating a tubing string extending down the well.          A swivel dognut assembly is provided, comprising inner and outer sleeves.   The tubing string is suspended from the inner sleeve which is rotatably supported from the stationary outer sleeve.  The outer sleeve is adapted to be suspended from the tapered inner surface of the casing bowl,  and is restrained from vertically upwards displacement by holddown screws.   The outer sleeve is almost entirely contained or recessed within the casing bowl.  A housing is bolted onto the casing flange.  A pair of worms extend through the housing and driveably engage a ring gear associated with the inner sleeve.   Because the sleeves are seated in the casing bowl, a compact rotator assembly is obtained.  In addition, the tubing rotator is designed to permit the housing to be removed and a blowout preventer ("BOP") to be installed for well servicing while continuing to maintain a seal between the swivel dognut assembly  and  the  casing  bowl,  thus  sealing  the  annulus  and preventing an otherwise possible blowout.   The  swivel  dognut assembly can subsequently be removed with the tubing string through the BOP.

Abstract: A control system emulates a multi-tasking environment using a single tasking processor. A number of predefined tasks are provided in a task library. When a host application needs processed data from a data source, the host application creates a pipeline of initialized instantiations of one or more of the tasks from the task library. When the host application invokes the pipeline, the data request is made from the host application to a downstream-most section of the pipeline. The data request ripples upstreamwardly to the upstream-most instantiation of one of the tasks from the task library. The upstream-most instantiation of a task obtains data from a data source and returns it downstreamwardly to the host application, each instantiation of a task from the task library further operating on the data.

Abstract: A transmission line switching apparatus comprises an optical fiber connecting board for holding a plurality of first optical fibers, an optical fiber arranging board, arranged apart from the connecting board with a predetermined spacing between them in the horizontal direction, for holding a plurality of second optical fibers, and a robot for handling the second fibers. Each second optical fiber extends to the connecting board through the arranging board, and the distal end of the second optical fiber is detachably attached to the connecting board so as to be selectively connected to one of the first optical fibers. When the distal end of the second optical fiber is attached to the connecting board, the second optical fiber is laterally extended in a loosened state between the two boards. In this state, the entangled states of the second optical fibers near the two boards are sparser than that in the intermediate position between the two boards. Therefore, the robot can easily handle the second optical fiber.

Abstract: Une batterie d'accumulateurs, nouveau modèle, nouveau format, incorporant, en plus des pièces et des cellules, composantes généralement incluses dans une batterie de type standard, un auto-sectionneur, dispositif de sécurité pour véhicules automobiles, composé principalement d'un boitier d'assemblage, de blocs et pivot de contact, transporteurs de courant et d'un mécanisme de déclenchement, actionnable par une secousse (tel une collision dans laquelle ledit véhicule automobile serait impliqué), laquelle action provoquera la rupture de l'alimentation électrique dans la batterie d'accumulateurs, avant la sortie dans le câblage électrique dudit véhicule. Le circuit est maintenu par un pointeau-contacteur inséré entre deux (2) bornes transporteuses, jusqu'à ce que le véhicule subisse un impact. Le balancier mécanique, composante principale pour l'action du sectionneur, projetté dans la direction de l'impact, force le pointeau-contacteur à s'éloigner des blocs de contacts et de ce fait, interrompt le circuit. On élimine ainsi les risques d'initier électriquement un incendie alors que le véhicule a été endommagé dans un accident, une collision, un dérapage, un renversement, un carambolage, ou autres.

Title: Hydrocyclone with turbulence creating means
Inventor: ANDERSSON ROINE
IPC: B04C5/081
Filed: 1992-11-26
Abstract: In a hydrocyclone the separation chamber (2) has a cir-cumferential wall (3) provided with at least one turbulence creat-ing member (12), which extends along the circumferential wall and crosses a helical path (10), along which a liquid stream is generated during operation. According to the invention, the turb-ulence creating member is formed by a set-off (12) on the circum-ferential wall (3). The set-off is formed and dimensioned such that said liquid stream substantially looses its contact with the circumferential wall, as the liquid stream passes the set-off. As a result turbulence is created in a layer of the liquid stream situated closest to the circumferential wall, without the liquid stream be-coming any substantial flow component directed inwards in the separation chamber.

Title: Auxiliary video data decoder with large phase tolerance
Inventor: TULTS JURI
IPC: H04N7/035
Filed: 1993-02-08
Abstract: An auxiliary video information decoder, for decoding auxiliary video information signals such as closed caption data, in-cludes a data slicer (210) having a variable slicing level. The slicing level is adjusted in response to the amplitude of a run-in-clock (RIC) signal that is included in the auxiliary video information portion of the video signal. Slicing level adjustment involves averaging the RIC signal amplitude during a substantially integral number of cycles of the RIC signal that occur during a control interval (RICWND). The timing of the RIC signal waveform with respect to the control interval is evaluated to verify that the de-sired number of cycles of the RIC signal occur during a control interval. The timing evaluation operation involves counting (250) cycles of the RIC signal during a control interval. If the desired number of cycles do not occur, the timing of the control interval is modified (200, 220, 230) with respect to the RIC signal and the timing is reevaluated during a subsequent control interval. The evaluation and timing-modification operations may be repeated until the desired number of cycles of the RIC signal are detected. If repeated operation does not provide the desired result, a control signal may be generated indicating that the video signal may not include auxiliary video information.
