Granted: 2007-07-03
Abstract: A product of reduced sulfur content is produced from a feedstock which is comprised of a mixture of hydrocarbons and contains organic sulfur compounds as unwanted impurities. The process comprises converting at least a portion of the sulfur-containing impurities to sulfur-containing products of higher boiling point by treatment with an alkylating agent in the presence of an acid catalyst and removing at least a portion of these higher boiling products by fractional distillation. Suitable alkylating agents include alcohols and olefins. In a preferred embodiment, catalytic cracking products which contain aromatic sulfur compounds as impurities are used as a feedstock for the process.

Filed: 1997-04-02
Granted: 2009-06-23
Abstract: A strategy for suppressing specifically or partially specifically an endogenous gene and introducing a replacement gene, said strategy comprising the steps of: 1) providing suppressing nucleic acids or other suppression effectors able to bind to an endogenous gene, gene transcript or gene product to be suppressed, and 2) providing genomic DNA or cDNA (complete or partial) encoding a replacement gene wherein the suppressing nucleic acids are unable to bind to equivalent regions in the genomic DNA or cDNA to prevent expression of the replacement gene. The replacement nucleic acids have modifications in one or more third base (wobble) positions such that replacement nucleic acids still code for the wild type or equivalent amino acids.

Abstract: The invention concerns an electrolysis apparatus for producing halogen gases from an aqueous alkaline halide solution with a plurality of plate-like electrolysis cells which are disposed adjacent one another in a stack, are in electrical contact, and each comprise a housing consisting of two half-shells of electrically conductive material with outer contact strips on at least one housing rear wall. The anode and the cathode are separated from each other by a partition wall, are disposed parallel to one another and are connected in an electrically conductive manner to the respective associated rear wall of the housing by means of metal reinforcements. The object of the invention is for the surfaces through which current flows to be as large as possible so as to prevent non-uniform current distribution. To that end, the metal reinforcements take the form of webs (10) which are aligned with the contact strips (7) and whose side edges (10A, 10B) abut the rear wall (3A, 4A) and the anode (8) and cathode (9) over the height of the rear wall (3A, 4A) and the anode (8) and cathode (9).

Title: Method of reducing or preventing scaling
Inventor: JOHANN JURGEN
IPC: C02F1/46
Filed: 1997-10-08
Granted: 2006-12-19
Abstract: An aqueous solution with a tendency towards scaling is passed through an electrolysis chamber having at least two reversible electrodes (6) and a bipolar electrode (7). The polarity of the electrodes (6) is reversed at time intervals. An alternating current can be applied alternatively to the electrodes instead of a direct current with regular pole reversal of electrodes. This method of processing enables scaling to be reduced considerably or even prevented, and the salt content of the solution is substantially maintained. The method is especially suitable to reduce or prevent scaling from natural waters, without substantially impairing water quality.

Abstract: An electrocoagulation treatment device includes a plurality of spaced reaction plates disposed within a reaction chamber. A voltage is applied to selected reaction plates to create an electrical field within the electrocoagulation chamber. The plates are arranged vertically with respect to the chamber which induces a vertical flow of liquid through a device.      Gases formed in the electrocoagulation process are allowed to rise to the top of the liquid line and can be vented to the atmosphere. The solids which precipitate out of the liquid stream are carried by the liquid stream to secondary separation.  Any remaining solids can be removed as sludge through a drain in the bottom of the device. A foam cover is provided to isolate the electrical connections of the plates from moisture. The top cover is provided to isolate the chamber for safety purposes. The device may be manufactured as a large industrial unit, a portable unit or a unit adapted for use within the home. The device may be operated in a pressure controlled environment, thus eliminating the need for a pump when the liquid stream is already pressurized. The voltage and amperage of the electrical field within the reaction chamber may be adjusted as necessary by placing selected reaction plates in electrical contact with the voltage source. The incoming line voltage itself may be kept at a constant which eliminates the need for a separate transformer. The reaction plates are easily removed from the reaction chamber and may be replaced individually or as a set.

Granted: 2009-06-16
Abstract: An array of sensors that are positioned underneath the wire of a paper makin g machine are employed to measure the conductivity of an aqueous wet stock. Conductivity of the wet stock is directly proportional to the total water weight within the wet stock; consequently, the sensor provides information used to monitor and control quality of paper sheet produced. CD water weight profile is obtained practically instantaneously and the MD and CD variations are essentially decoupled. Quality improvements to the sheet fabricated are achieved by providing fast control of the actuators and by tuning components to eliminate sources of variations. D ry stock weight of wet stock sheet resting on a water permeable moving wire can be measured employing a water weight sensor element positioned adjacent to the wire generating signals indicative of water weight of the sheet. The moisture level CD profi le of a sheet of material can also be measured.
