Title: Combined microwave and optic rotary joint
Inventor: ANDRIEU FRANCOIS
IPC: G01S7/03
Filed: 1991-05-21
Abstract: This combined microwave and optic rotary joint has a fixed part and a rotating part in rotation about an axis p in relation to the fixed part. It has at least one pair of microwave guide inputs, one of which is positioned in the fixed part while the other is positioned in the rotating part, these microwave guide inputs being coupled to each other by a coaxial link that is fixedly joined to the rotating part and placed in a conduit going through the fixed and rotating parts along the rotation axis d The core of the coaxial link is drilled with a longitudinal channel enabling the passage of an optic fiber fixedly joined to the rotating part. The end of this optic fiber goes through the fixed part and emerges in a case where it is coupled through an optic rotation plane to the end of another optic fiber fixedly joined to the fixed part.

Title: Method for monitoring real-time hydraulic fracture propagation
Inventor: ABOU-SAYED IBRAHIM S
IPC: G01V1/42
Filed: 1991-06-18
Abstract: ABSTRACT       A process for monitoring real-time hydraulic fracture propagation wherein remote microseismic activity is utilized. Selectively placed geophones detect generated longitudinal and shear-waves which give an estimate of direction of the fracturing.  Having obtained the direction of the fracture, polarization is used to obtain the fracture source.  Subsequently obtained microcracks which define the main fracture boundary are recorded as microseismic events.  Microcracking in the formation is sequenced in time thereby allowing the real-time fracture height to be estimated.

IPC: E02B17/00
Filed: 1990-07-11
Abstract: The invention relates to a jackable oil rig designed for large ocean depths and which comprises at least one leg and a deck having a jack system. The rig's leg comprises a number of corner columns together with transverse bracing stays and each corner column comprises a substantially annular outer pipe (26) in which a substantially annular inner pipe (28) is arranged. The annular space (27) between the inner wall of the outer pipe and the outer wall of the inner pipe is filled with a hardenable material such as concrete, capable of transferring forces between the pipes, the outer diameter of the outer pipe (26) being approximately constant over the whole length of the column (24), and the oil rig is characterised in that the outer diameter of the inner pipe (28) is approximately constant while its wall thickness ti increases from upper section (I) of the corner column to the lowermost section (VI) of the corner column. According to a preferred construction the wall thickness ti of the inner pipe (28) increases step by step from about 30 mm in the upper section of the rig leg to about 150 mm in the lower section of the leg. This corner column construction makes it possible to produce jackable oil rigs which can operate at ocean depths completely down to 200 metres.

Abstract: BRACE FOR PROPANE GAS CYLINDER LIQUID LINE   ABSTRACT OF THE DISCLOSURE     An improved aluminum propane gas cylinder with a braced liquid line or pipe.   The brace is welded to a joggle formed in the rim of the cylinder top head section, and includes a pair of tines which are crimped around the liquid pipe to secure it against vibration.  Securing the brace to the top head joggle permits assembly of the liquid pipe to the brace before joining the top and bottom head sections, and complies with regulations against welding to the straight surface of the cylinder.  With the liquid line braced in this manner, the susceptability of the liquid line to fatigue cracking is substantially reduced.

Title: Method for environmentally benign paint spraying with an air-drying lacquer dissolved, emulgated or dispersed in water
Inventor: WEPF HANS-PETER
IPC: B05D7/24
Filed: 1992-03-24
Abstract: In the process of spraying in a cubicle having a water-rinsed rear wall, the cubicle waste water is separated by ultrafiltration into permeate and lacquer-containing residue. The permeate is recycled. Fresh spraying composition is fed-in. The lacquer preferably is an alkyd resin, an acrylic resin, a polyvinyl acetate resin, a silicone resin, a copolymer thereof, a mixed polymer thereof or a mixture thereof. The spraying composition comprises a component for preventing coalescence, preferably one or several aliphatic amines having an average molecular weight of 75 to 133 or mixtures or derivatives thereof, and a component for retardation of the drying. If the lacquer is capable of being emulgated or dispersed in water, the spraying composition and/or the cubicle waste water preferably comprises a component for stabilizing the emulsion or dispersion. A component for adjusting the throughput in the ultrafiltration is admixed to the cubicle waste water, preferably a derivative of glycol or of a higher alcohol. The spraying composition and/or the cubicle waste water additionally may contain a biocidal component. The conductibility of freshly fed water is kept below a predetermined limiting value preferably of 10-4 .OMEGA.-1cm-1, which is preferably achieved by reverse osmosis.      The lacquer-containing residue of the cubicle waste water is enriched by removing water until its lacquer content is about equal to that of fresh spraying composition. The enrichment and reuse may proceed in essentially continuous or discontinuous manner, in the latter case the lacquer-enriched residue is stored intermediately.

Title: Process for the bleaching of chemical pulp
Inventor: VAHERI MARJA
IPC: D21C9/16
Filed: 1991-02-01
Abstract: The invention relates to a process for the bleaching of chemical pulp, process which comprises one or several oxidation steps and one or several alkali treatment steps and in which the pulp is treated with an enzyme. The essential idea of the invention is that the pulp is treated with an enzyme in two or more different steps of the process, an oxidation and/or alkali treatment being most preferably carried out between the enzyme treatment steps. The oxidizing chemical used is most preferably oxygen, although peroxide and/or chlorine and/or chlorine dioxide can also be used in addition to or instead of it, and in the enzyme treatment steps, which preferably number 2-4, the same enzyme or alternatively two or more different enzymes may be used. By the enzyme treatment according to the invention, the amount of toxic organic compounds inthe bleaching effluent is decreased and at the same time the chemical oxygen consumption of the effluent is decreased.

IPC: D21F9/00
Filed: 1991-04-18
Abstract: A paper machine for the manufacture of a soft crepe paper grade, which in respect of bulk and softness is fully comparable to the one manufactured in a paper machine made for through-air drying by hot air, is in principle a conventional soft crepe paper machine, in which a conveying and imprinting fabric (25) is substituted for the pick-up felt. A pick-up device (23) operating with air flow picks up the web (15) from the forming fabric (9) and transfers it to the imprinting fabric (25) without any appreciable compaction of the web (15). The imprinting fabric (25) is maintained clean and dry by cleaning devices (41, 43, 45) and a device (47) for depleting the imprinting fabric (25) of water before it arrives at the pick-up device (23). Further, air current generating devices (35, 37, 39) are provided for removing water from the paper web (15) by passing air of ambient temperature through the web (15). These have a capacity that is sufficient for raising the dry solids content of the web to at least 25 % before the web arrives at the Yankee dryer (29). If desired, the paper machine may easily and in a short time be converted into a conventional soft crepe paper machine, essentially by substituting a pick-up felt for the imprinting fabric (25).
