Title: Method and an apparatus for maintenance of valves included in subsea production system for oil and gas
Inventor: ANDERSSON ROLF J
IPC: B63C11/52
Filed: 1987-10-21
Granted: 1991-01-15
Abstract: ABSTRACT OF THE DISCLOSURE:            A method and an apparatus for replacing an insert unit included in an insert valve assembly belonging to a subsea production system for gas and oil.  In carrying out the method, a manipulator is brought by means of a sheave, a hoisting cable and guide wires down to a predetermined location on the bottom of  the  sea.   The  manipulator comprises a telescopic arm which is then moved towards and fixed by means of a hook and a lug to a valve tree which supports  a valve,  the insert unit of which is to be unscrewed from the respective valve housing and be replaced. A carriage located in the  manipulator and comprising retracting, aligning and fixing devices is brought with the aid of the telescopic arm and a rail, located on the top side of the carriage, towards the valve tree and is fixed to retraction cones mounted on the valve tree.  This allows a moment producing tool, mounted in the carriage, to grapple that castellated nut which holds together the insert unit and valve housing of the valve.  Thereafter, a releasing moment is applied on the castellated nut,  whereby the castellated nut with the insert unit is unscrewed from the valve housing and the valve tree.  The carriage with the insert unit is separated from the valve tree and is brought back via the telescopic arm to the manipulator.  The insert unit of the valve is replaced by a new insert unit, either by a new insert unit stored in the manipulator and with the aid of gripping arms present in the manipulator, or by raising the manipulator to the surface where replacement can be carried out, whereafter the carriage is again moved towards and fixed to the valve tree.  This also allows the moment producing tool to move the new insert unit with its castellated nut towards the valve housing, whereupon a tightening moment can be applied.

Title: Pipelineable syncrude from heavy oil
Inventor: HECK ROLAND H
IPC: C10G9/00
Filed: 1988-11-01
Granted: 1993-03-09
Abstract: ABSTRACT OF THE DISCLOSURE    Heavy crude oils unsuitable for pipelining without addition of solvent or cutter stock are upgraded by a mild thermal treatment which is more severe than conventional visbreaking but less severe than delayed coking, followed by a mild, solvent-deasphalting step.  The mild solvent-deasphalting is effective in rejecting a major fraction of the metals and Conradson Carbon Residue of the crude, and directly produces a pipelineable syncrude of much better quality than the original crude for cracking and/or hydrocracking.  The asphalt by-product is burned to produce process steam necessary for the production of the crude.  The process described minimizes investment and operating cost, and is adaptable to skid-mounting for on-site operation.

Abstract: IMMUNOAGGLUTINATION MEASUREMENT APPARATUS          ABSTRACT OF THE DISCLOSURE:      A buffer solution is sampled from a buffer solution vessel and is dispensed into a reaction vessel on a reaction table by first sampling/dispensing means, and a specimen containing an antigen or antibody to be measured is sampled from a specimen vessel and is dispensed into the reaction vessel by second sampling/dispensing means.  A reagent containing insoluble carriers to which is bonded an antibody or antigen that specifically reacts with the antigen or antibody in the specimen is sampled from a reagent vessel and dispensed into the reaction vessel by third sampling/ dispensing means.  The entire reaction table is shaken con-tinuously during mixing of the buffer solution, reagent and specimen, and the reaction vessel is maintained in an isothermal state.  A stable antigen-antibody reaction in the resulting reaction solution is thus promoted to form an agglutinate of the insoluble carriers.  The reaction solution is sampled from the reaction vessel and dispensed into a sample chamber by fourth sampling/dispensing means. The dispensed reaction solution is transferred to a detector through which the insoluble carriers are passed and in which a signal is generated based upon a difference in terms of electrical or optical characteristics.  The degree of agglutination of the insoluble carriers is obtained as a numerical value, thus making it possible to quantify the antigen or antibody of interest contained in the specimen.
