Title: Mineral well heating systems
Inventor: BRIDGES JACK E
IPC: E21B36/04
Filed: 1988-09-19
Granted: 1992-01-14
Abstract: MINERAL WELL HEATING SYSTEMS          Abstract of the Disclosure Heating systems for mineral wells (e.g. oil wells) employ electrical power sources, sometimes operating at relatively high frequencies, that are connected to the well casing and production tubing so as to provide a coaxial line electrical heater projecting down into the well.  The heating pattern of the coaxial line is effectively controlled so that most of the power is dissipated as heat, primarily in the tubing, above a depth D above which paraffins or other condensible constituents would tend to condense or otherwise impair the flow of mineral fluid up through the production tubing.  The applied electrical power is controlled so that the fluid is kept approximately at or only somewhat above the flow impairment temperature for constituents of the fluid.  In some embodiments the system is extended to provide heating of a portion of the deposit formation adjacent to the well.

Title: Refining of raw gas
Inventor: EKSTROEM CLAS
IPC: C10K1/00
Filed: 1988-09-30
Granted: 1995-05-30
Abstract: The invention relates to a process for the refining of a raw gas produced from a carbonaceous material by means of a gasification process, refining taking place in a secondary stage separated from the gasifier. In order to reduce the gas contents of tar in the form of organic compounds condensible at lower temperatures, such as ambient temperatures, and of ammonia, the refining is carried out in a secondary stage being a fast circulating fluidized bed, the bed material of which at  least mainly being an active material in the form of a material that is catalytic for tar and ammonia conversion, whereby a catalytic conversion of tar and ammonia contained in the raw gas is obtained. In order to decrease the content of hydrogen chloride in the gas, an active material that can absorb chloride also is used. Fresh catalytic and absorbing material is supplied in an amount sufficient to have the hydrogen chloride present in the raw gas absorbed on the material, a corresponding amount of the material containing absorbed chloride being discharged from the secondary stage.

Abstract: ABSTRACT OF THE DISCLOSURE          An electrohydraulic servo system for controlling pressure of fluid in a cavity of undetermined volume includes a valve having a valve spool element and ports for supplying fluid as a function of position of the valve element within the surrounding valve body.  A servo valve is responsive to electronic valve control  signals  for controlling pilot pressure within the main valve body and thereby controlling position of the valve element. An electronic valve controller receives  a  pressure  command signal  from remote master electronics as a function of desired fluid pressure within the cavity volume, and a pressure feedback signal indicative of fluid pressure within the cavity volume from a pressure sensor coupled to the valve output ports.   The pressure command signal is compared to the pressure feedback signal in a pressure-control mode of operation, and a difference or error signal is employed for generating valve control signals to the servo valve.  A second sensor is coupled to the valve element for supplying a position feedback signal as a function of position of the valve element within the surrounding valve body.   Both position and pressure feedback signals also employed in the pressure control feedback loop, with the pressure feedback signal being varied as a function of a gain Kp, the position feedback signal being varied as a function of the gain Kd, and the difference or error signal being varied as a function of the gain Ke.  Cavity volume is determined as a function of the pressure and position feedback signals.  Control loop gains, specifically gains Ke and Kd, are varied as a function of cavity volume for thereby adapting the servo control system for either intended or unintended variations in cavity volume.

Granted: 1993-05-25
Abstract: ABSTRACT OF THE DISCLOSURE           A series resonant power converter in which a resonant capacitor is commonly used in a series resonant circuit and a parallel resonant circuit, whereby a capacitance of the resonant capacitor can be considerably decreased as compared with that of a tank circuit according to a prior art, so that an energy handled by the resonant capacitor can be decreased, which results in decreasing a size of the resonant circuit and also decreasing a power loss. The converter includes means for detecting and com-puting a voltage-applied across a main switch means in its OFF-state and a control circuit for driving the main switch means to its ON-sate when the detected and computed value of the voltage drops to a minimum voltage required to sustain oscillation of the series resonant circuit.  The minimum voltage can be obtained by computing the signals fed from the detecting circuit for detecting an input voltage, a detecting circuit for detecting a voltage of a second resonant circuit and a detecting circuit for detecting a DC output voltage converted to a primary side of a main transformer.

Abstract: A door closer includes a tension member comprising spaced shafts acted by springs and connected to articulated chains which are coupled to an anchor plate secured to the door frame. Movement of the shafts is under the control of a uni-directionally operative fluid-filled damper having a piston carried by a piston rod which is connected to a cross head slidably mounted on the shafts and held against abutment washers by the springs. The damper serves to regulate the rate of movement of a door in the direction of closure without restricting significantly the rate of movement in the direction of opening. A fluid by-pass is provided in the damper by a rebate formed in the cylinder so that as the piston approaches the end of the cylinder over the final part of the closure movement the restraint imposed by the damper is relieved. The point in the closure movement at which the fluid by-pass becomes operative can be varied while the closer is installed so as to provide compensation for variations in the installation of the closer and variations of the gap between the door and its frame. In one embodiment this is achieved by securing the chains to an adjustment plate which is movable towards and away from the anchor plate. In another embodiment the piston rod is adjustable secured to the cross head, which in this case is in the form of a stirrup with a cross member on which the piston rod is carried presented towards and accessible from the outer end of the housing so as to enable the piston rod to be adjusted.
