Abstract: PCT No. PCT/NO95/00033 Sec. 371 Date Oct. 11, 1996 Sec. 102(e) Date Oct. 11, 1996 PCT Filed Feb. 14, 1995 PCT Pub. No. WO95/21683 PCT Pub. Date Aug. 17, 1995A method for removing and preventing emissions into the atmosphere of carbon dioxide (CO2) from exhaust gases from gas turbines for the production of oil and gas, comprising the following steps: (a) natural gas and air are introduced into a gas turbine in which natural gas is converted to mechanical energy; (b) the exhaust gas from the gas turbine is passed through a heat recovery unit for recovery of the heat content in the exhaust gas; (c) after emitting heat in the recovery unit whereby the temperature of the exhaust gas has been reduced to 20 DEG -70 DEG  C., the exhaust gas is passed to an absorption column containing an absorption liquid, where the carbon dioxide is absorbed in the said liquid, and the thereby purified exhaust gas, essentially free of carbon dioxide, is vented to the atmosphere; (d) the absorption liquid which contains CO2 is passed to a stripping column where the CO2 is removed from the absorption liquid heated to a temperature of 120 DEG -150 DEG  C.; (e) the thereby regenerated absorption liquid which is essentially free of CO2 is recycled to the absorption column and the separated CO2 gas is passed to a compression stage for compression and utilization or disposal; wherein approximately 40% of the exhaust gas is recycled to the compressor air inlet for said gas turbine before the exhaust gas is passed to the absorption stage (c).

Abstract: The tool includes a central section having a left-hand drill bit section at one end and an extraction section at the other. The extraction section tapers toward its distal end and is formed with left-hand threads on the exterior of the taper. The distal end is chamfered at an angle more abrupt than the taper so that the chamfer intercepts the threads and so that the threads rise outward in a short axial distance and are able to bite into the margins of a shallow hole drilled in the bolt remnant by the bit section.

Abstract: The vessel comprises a part having an end portion which is introducible into a second vessel part and which has a cylindrical outside surface formed with an annular recess. The second vessel part has a connecting part having a cylindrical inside surface formed with a recess in the form of an annular groove and having a connecting duct which extends from the outside into the recess tangentially. When the two cassing parts are in a connected position the two recessee bound a guide duct for a flexible closure part which is made, for example, of a steel string or cord or the like and which is introduced through the connecting duct into the guide duct to interconnect the two casing parts and withdrawn from the guide duct to release the two casing parts (1, 1a, 2a). The vessel is of use, particularly in association with a facility for filling a gas fuel tank, as a pressure-resistant casing for control and/or switching elements and can be opened with reduced manual intervention for the inspection and servicing of the latter components and closed reliably.

Abstract: A method of making a measuring tube for an electromagnetic flow meter starts with a tube member (2)  of non-magnetic metal  with  electrodes (9)  arranged  in  throughpassages  (10).    An  insulating  lining  (15) consists of an enamel priming layer (16) which is continued in the gap (12) between the electrode (9) and inner surface of the throughpassage (10).   A covering enamel layer (17) can complement the lining (15).          The end face (13) of the electrode (9) projects beyond the inner sur-face (14) of the tube member (2) and is in each case cleaned of the slip before the enamel is melted.  This results in a simple production giving reproducable results.

Title: Method of detecting escape or spillage of a cold liquid
Inventor: PAINTER DAVID MICHAEL
IPC: F17D5/02
Filed: 1991-04-26
Granted: 1997-05-13
Abstract: To detect escape or spillage of a cold liquid, for example liquefied natural gas, a narrow, robust, flexible, resilient, plastics tube, placed where the escaped or spilled cold liquid can contact it, is filled with carbon dioxide gas from a gas supply via a non-return valve and a pressure regulator which ensures that the maximum pressure in the tube  is at a desired value which is preferably greater than the pressure of the ambient atmosphere surrounding the tube.  A gas pressure drop detector  is provided to observe a pressure drop in the tube.  Should escape liquefied natural gas contact the tube the latter is so cooled that the carbon dioxide gas inside de-sublimates to a solid of greatly reduced volume causing a marked drop in pressure in the tube.  This is observed by the pressure drop detector which initiates a warning or some safety action.  A gas flow restrictor ensures that the gas supply cannot rapidly re-charge the tube before the pressure drop detector has responded to the pressure drop.

Title: High solids cb printing ink which produces a black image
Inventor: SEITZ MICHAEL E A
IPC: C09D11/02
Filed: 1991-09-10
Granted: 1996-11-26
Abstract: A high solids content, aqueous, microcapsule-containing printing ink is prepared by forming microcapsules in situ in a printing ink vehicle. The microcapsules are preferably prepared by interfacial polymerization or interfacial crosslinking between a reactant, such as a polyisocyanate dissolved in an oily solution and a coreactant such as a polysalt of casein and diethylene triamine present in an aqueous solution into which the oily solution is dispersed. The aqueous solution contains water and preferrably a non-volatile diluent such as a non-reducing sugar, for example methyl glucoside. The oil-containing microcapsules contain an oil solvent and a mixture of dye precursors which upon reaction with a color developer produces an intense black image. The printing ink preferably has a 60-70% by weight solids content and may be used as a low-coat-weight CB coating for preparing carbonless copy paper.
