Title: Separation of bitumen and water in a separator vessel
Inventor: KOVALSKY JAMES A
IPC: C10G1/04
Filed: 1992-05-26
Abstract: "SEPARATION OF BITUMEN AND WATER IN A SEPARATOR VESSEL"    ABSTRACT OF THE DISCLOSURE         The feedstock to the process is the produced fluid emulsion from a steam-assisted gravity drainage process conducted in a subterranean oil sand reservoir.  This stream is an emulsion of bitumen and water.  The feedstock is temporarily retained in a  gravity  separation vessel  for about  an hour  at  elevated pressure and at a temperature of at least 205°C, preferably about 215°C, in contact with an effective concentration of chemical demulsifier.  Under these temperature conditions, the density of the bitumen is sufficiently greater than that of the water so that gravity separation will occur effectively and the bitumen can be recovered from the base of the vessel and the water from the upper portion of the vessel.

Abstract: An apparatus for capturing and recording the content, ownership, and/or bibliographic source of documents reproduced on a reprographic device, and more particularly for tracking the reproduction of specified information, especially copyrighted documents, is connected, preferably detachably, to any of various reprographic devices. The apparatus includes a digitizer for digitizing desired pages (such as those containing title and author information) output from a main portion of the reprographic device, a recording device and medium for storing said digitized pages, a counter for counting the number of reproductions made and optionally inferring the number of originals, a controller for controlling the operation of the apparatus and, optionally, a control panel for interacting with the operator of the reprographic device. When reproducing copyrighted information, an operator makes a reproduction of the pages containing title and author information, digitized images of these pages being stored on the recording medium. The counter counts the total number of copyrighted and other reproductions made, the counted number of reproductions also being recorded on the recording medium. The recording medium is then used to determine the number and nature of copyrighted reproductions made by the reprographic device. The device may also be used for other applications where reproduction of particular types of documents is restricted, or for storing document contents as part of an information storage and retrieval system.

IPC: H03G3/30
Filed: 1991-11-27
Abstract: A closed loop automatic gain control (AGC) circuit with high dynamic range capabilities having an amplifier circuit (18) for receiving an input signal, which is susceptible to variations in signal power, and a control signal. The amplifier circuit (18) is responsive to the control signal for amplifying the input signal at a gain level corresponding to the control signal so as to provide a corresponding output signal. A measurement circuit (20) is coupled to the amplifier means (18) for measuring logarithmic sig-nal power of the amplified input signal and providing a corresponding linear measurement signal. An integration circuit (22) is included for receiving the measurement signal, and a reference signal which corresponds to a desired signal power of the output signal. The integration circuit (22) integrates with respect to time the difference between the measurement signal and the reference signal, and generates the control signal which corresponds to the result of the integration.

Title: Inner treatment process and device for inaccessible pipes
Inventor: MORGENEGG ALFRED
IPC: F16L/
Filed: 1992-08-28
Abstract: ABSTRACT OF THE DISCLOSURE       The process uses a remote-control robot with a video-monitored working head.  The part to be opened or repaired is cut out, or a pig is placed and inflated so as to be clamped in the pipe at the part to be sealed.  The process is mainly characterized in that the desired cut-out part is sealed with a two-component epoxy resin.  Both components are mixed in an opposite flow helical mixer just before reaching the working head, forming an intimate, curing epoxy resin mixture. The device had a front rotary disk wheel arranged on the robot, that carries a fork provided with an articulation.  A pivotable and retractable working head is mounted between the ends of the fork.  The working head may be designed as a cutting unit, as an inflating unit for clamping pigs, as a pressing unit for pressing and smoothening epoxy resin, as a whirling unit for coating the inside of pipes or as a combination of such units.

Title: Method and apparatus for relieving a capacitor of a controlled series compensator as a function of the load on its arrester
Inventor: UNTERLASS FRANZ-JOSEF
IPC: H02H7/16
Filed: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE     A method and an apparatus for relieving a capacitor of a controlled series compensator as a function of the load on its arrester when high-current line faults occur. The current flowing through the arrester is used to determine its absorbed energy, from which a temperature gradient is then determined as an indicator of a sudden load on the arrester and compared with a limit value. This comparison value is processed, as a function of the determined actual arrester temperature and the measured line current, to yield a control signal. The power converter valve of the controlled series compensator is triggered in response to this control signal in such a way that its equivalent impedance is switched from capacitative to inductive. The number of disconnections required as a result of high-current line faults is thereby considerably reduced, thus greatly increasing availability of the system.

Abstract: A carton is disclosed having a reclosable pour spout formed in a top panel thereof. The pour spout being formed by cooperating portions of an upper minor flap, an exterior top panel and an interior top panel which cooperate to form the top panel of the carton. A portion of the interior top panel forming a central closure pane is formed by inside and outside cut scores formed in the interior top panel defining a ply-separation region therebetween which extends from a lift tab to a hinge line formed in the interior top panel.  The exterior top panel includes a central closure pane defined by lines of perforation which exend from the lift tab to a hinge line formed in the exterior top panel which overlies the hinge line formed in the interior top panel, such that upon the application of an opening force to the lift tab, ply-separation occurs in the ply-separation region of the interior top panel which consequently forms a stop lip in the interior top panel and a stop tab on the central closure pane which when reclosed contacts the stop lip and prevents the central closure pane from being inserted into an interior of the carton.
