Patent EP-0542838-A1 (EP)
Title: Process for recovering sulphur from a h 2?s-containing gas stream under high pressure.
Inventor: HEISEL MICHAEL
IPC: C01B17/04
Filed: 1991-08-09
Abstract: A process allows gas streams under high pressure to be desulphurated with comparatively little equipment but with a high recovery rate. For that purpose, H2?S is directly oxidized into sulfur by catalysis in at least one reactor. It is advantageous to use two reactors; the first one in the direction of the flow is an adiabatically driven reactor without inner cooling, through which the gas stream flows preferably upwards, whereas the second reactor in the direction of flow is advantageously a reactor interiorly cooled down to a temperature below the dew point of sulphur, through which the gas stream flows preferably downwards. In both reactors, different catalysts are generally used, although both catalysts are essentially composed of TiO2? and oxidize H2?S directly and selectively, but not H2? and CO. In the first reactor without inner cooling, H2?S is directly and selectively oxidized under high pressure through the catalyst. In the second interiorly cooled reactor, the reaction continues, whereas the sulphur that separates by condensation has in itself a catalytic effect, under the prevailing high pressure. Thus the regeneration of this reactor of liquid sulphur can be dispensed with. The sulphur produced condensates and is separated from the high pressure gas stream. The whole desulphuration process can be further improved by reduction of the sulphur compounds and/or sulphur vapours into H2?S and/or by adsorption, chemisorption or NaOH-washing of H2?S, the residual sulphur compounds and/or the sulphur vapours.

Title: Enzymatic synthesis of oligonucleotides.
Inventor: RICHARDS RODNEY M
IPC: C12Q1/68
Filed: 1991-09-23
Abstract: The present invention makes possible the catalytic production of sequence specific oligonucleotides through the use of a specially designed template sequence. The reaction can be made to proceed isothermally in the presence of an excess of nucleoside triphosphates, an agent for polymerization, and a cutting agent. Because the process is catalytic with respect to the template sequence, an unlimited amount of oligonucleotide product can theoretically be generated from a single molecule of template. Where the process is initiated by the presence of a nucleic acid target sequence, the method of the present invention can be used for diagnostic purposes as an amplification method to improve sensitivity. Diagnostic sensitivity can be further enhanced by employing a cascade of these template sequences.

Abstract: Procédé se rapportant à un filtre à gravier pour un puits de forage (12) dans lequel du sable recouvert de résine ou "gravier" est utilisé. Tout d'abord, le puits de forage est perforé à l'endroit de production de façon à fracturer la formation (10) par un procédé hydraulique. Par la suite, la formation est fracturée par un procédé hydraulique au moyen d'un fluide de fracturation contenant du sable recouvert de résine. Au cours de l'opération de fracturation, la fracture (20) qui en résulte est étayée par le sable recouvert de résine. Le fluide de fracturation est pompé dans le puits de forage jusqu'à ce qu'un criblage ait lieu au niveau des perforations du puits de forage. On laisse le sable recouvert de résine dans la fracture, les perforations et le puits de forage jusqu'à ce qu'une masse consolidée, perméable et poreuse soit formée. Après que cette masse se soit formée, l'excédent de sable consolidé (22) est enlevé du puits de forage. Lorsque la formation est produite, les solides de la formation sont retenus par la masse consolidée dans la fracture et les perforations. Selon un mode de réalisation alternatif, la pression du fluide de fracturation est maintenue en dessous de la pression de fracturation.

Abstract: This invention relates to an improved process for producing gypsum calcium sulfate dihydrate flakes from powdered gypsum calcium sulfate dihydrate obtained from the desulfurization of flue gas by the wet limestone process. The flakes have sufficient size and strength such that the gypsum calcium sulfate dihydrate can be handled and processed in conventional equipment commonly used by wallboard manufacturers and others in the construction industry. The intermediate calcium sulfate dihydrate from the desulfurization process is dewatered to about 5 to 12% by weight and then compressed into a thin sheet under a compaction or compression load of 4 tons force to 15 tons force per linear inch of sheet width. A linear speed of from 0.5 to 2.5 feet per second is maintained during compaction providing a compaction residence time of from about 0.2 to 1.2 seconds. An elevated temperature is maintained during the compaction process to enhance the reformation of the crystal size and shape of the gypsum calcium sulfate dihydrate. 
     The combination of pressure and temperature on the moist gypsum calcium sulfate dihydrate alters the physical characteristics of the gypsum calcium sulfate dihydrate, thereby resulting a sheet which breaks into hard flakes on exit from the compaction zone.

Abstract: The motor-vehicle is provided with side tracks (C1-C2) with respective electric motors (11-111) which actuate speed reducers (17-117) pivoted with their input shafts (16) on the inner side of said tracks and having keyed on their output shafts respective rubber-coated wheels (18-118) and respective pinions (19-119). The reducers are associated with raising/lowering units (22-122) which, when the motor-vehicle travels on its tracks, keep the rubber-coated wheels lifted from the ground and cause said pinions to mesh with ring gears (20-220) which are keyed to one of the wheels (3) for said tracks which are thus connected to the propelling motors. On the contrary, when the vehicle travels on its wheels, the reducers are lowered to cause the rubber-coated wheels to engage the ground and the tracks are kept in a lifted condition, with simultaneous disengagement of the pinions from the ring gears for said tracks. 
Provided at the front side of the motor-vehicle is at least one steering wheel (28) which can be raised/lowered simultaneously with the rear wheels and which is provided on its shaft with a potentiometer permitting an accurate control of the motors during the steering of the motor-vehicle.

Abstract: In manually actuable blind riveters (10), a front sleeve (14) is arranged on the front side of a riveter housing (12) and a mouthpiece (18) for receiving a mandrel is fixed in the front end of the said sleeve. Arranged in the front sleeve (14), behind the mouthpiece (18), is a chuck (20) for the mandrel and this chuck is connected to a movable pulling piston (24) extending through the riveter housing (12) and having an interior designed as a discharge channel (26) for mandrels which have been torn off. Arranged laterally on the riveter housing (12) are two articulated levers (42) for the transmission of an axial force component to the mandrel leading to a stroke during the actual riveting process. In such blind riveters, the force required to set a riveted joint increases with the size and thickness of the blind rivet to be set. With the blind riveter according to the invention, on the other hand, blind rivets of various sizes and thicknesses can be set in a simple manner with essentially the same expenditure of force in all cases. This is achieved according to the invention by virtue of the fact that the stroke of the pulling piston (24) can be adjusted by altering the distance between the mouthpiece (18) and the chuck (20). <IMAGE>
