Title: Improved process for the polymerization of polar compounds
Inventor: FLEISCHMANN GERALD
IPC: C08F4/72
Filed: 1990-01-17
Abstract: IMPROVED PROCESS FOR THE POLYMERIZATION OF POLAR COMPOUNDS                  Abstract of the Disclosure The invention relates to an improved process for the polymerization of polar compounds which have a C=C double bond in the .alpha.-position to a carbonyl, nitrile, sulfone, phosphone or nitro group, such as, for example, acrylic acid derivatives, .alpha.-nitroolefins, vinyl sulfone derivatives and vinyl phosphonic acid esters.  The quasi-ionic polymerization is initiated by organometallic compounds of silicon, german-ium and tin as initiators together with nucleophilic or electrophilic catalysts, and is carried out at temperatures in the range of from -100°C to +100°C, in which the initiators are selected from silanes, germanes, stannanes, siloxanes, germoxanes or stannoxanes having at least one metal-bonded allyl or propargyl group, which may be substituted by hydrocarbon groups, per metal atom.

Title: Process for the preparation of hydrogen peroxide (i)
Inventor: MAUNULA TEUVO
IPC: C01B15/023
Filed: 1990-01-26
Abstract: Abstract The invention relates to a process for the production of-hydrogen peroxide by the anthraquinone process. A reaction mixture into which there are fed hydrogen or a hydrogen-containing gas and a working solution, i.e. an anthra-quinone derivative in an organic solvent, is circulated via a tubular static mixing zone (9) which is continuous or comprises several parts, in order to hydrogenate the anthraquinone derivative in the presence of a solid cata-lyst, and by removing hydrogenated working solution (13) and gas (11) from the circulating reaction mixture (8). According to the invention, the reaction mixture (14) is circulated (8) via a catalyst-coated static mixing zone (9), where it is simultaneously both mixed and catalyzed.
Patent CA-2009649-A1 (CA)
Inventor: HYZAK JOHN M
IPC: B21J5/00
Filed: 1990-02-09
Abstract: Two pieces of metal are bonded together at a surface by placing the two pieces into contact at the surface and forging the two pieces in a die which causes substantial displacement of the metal originally at the surface in a direction parallel to and outwardly from the edges of the surface and into vents in the face of the die and within the die impressions.  The strain and displacement fields are controlled by the die and vent geometry which is designed to concentrate the strain and displacement along the original bondline. In this way, up to 99.9%+ of the defects which are potentially present at the original surface are efficiently displaced with moving metal away from the original contact between the two pieces of metal into sacrificial ribs that form in the vents and the remaining defects are subjected to significant strain. A portion of the displaced metal which contains many of the defects and which forms the sacrificial ribs is removed  from the  resulting  bonded workpiece  as  the sacrificial ribs are removed from the workpiece.   The result is a bond with superior properties and with a bond surface which can be located very precisely both in orientation and location (e.g., radial distance from the center  of  a  disk).    This  system is  particularly appropriate for forming dual-alloy high-pressure turbine disks for gas turbines in which an annular peripheral ring of a second superalloy is bonded to a central core of a  first superalloy.   The  system is particularly effective if, prior to forging, surfaces to be bonded are closely  shape-conforming,  are  very  clean,  and  are diffusion-bonded using hot isostatic pressing while the surfaces are gas-free.  The sacrificial ribs are formed by vents in the impressions of the forging dies.  The vents  are adjacent to the  outer edges  of the bond surface.  The system may be accomplished by using one or more strikes in the same dies or same die geometry, or may include multiple strikes in which only one side of the bond is in proximity to a vent during each strike. Subsequent strikes would process the bondline resulting from the previous strikes, but with the rib removed.  The die impressions would be so shaped that the resulting die cavity would closely conform to the original workpiece shape, except for the vents, so that metal displacement and strain would be concentrated at the bondline.

Abstract: ABSTRACT         A curtain wall for a building structure is provided in which structural members and diaphragms are used to reinforce a relatively light frame such that the number of connections to the building required is reduced to one or two.  As a result, problems associated with differential settlement or deflection of the building are minimized, handling and installation is simplified, and the associated costs  are  reduced.    Novel  connection  means  are  also provided which enable the individual wall modules of a multimodule  building  to  be  aligned  and  repositioned independent  of  their adjacent  wall  modules  after  all modules have been erected  and are supported upon the connections.   The curtain wall module comprises a frame having a top and bottom chord and a plurality of transverse studs spaced at intervals along the length of the chords defining  a  plurality  of  panels.    Exterior  cladding including a layer of sheet metal is mounted to the exterior face of the frame strengthening the frame as a stressed diaphragm.  In the preferred embodiment the top chord of the frame includes a relatively strong reinforcing beam (such as a square hollow structural section) parallel to and connected to the top chord along the full length of the top chord.  The weight of the wall may be supported upon the building by vertically adjustable connectors at two points on the beam.  Vertical pins connected to the upper surface of the beam project through the bottom chord web of a like upper adjacent wall module.   Diagonally slotted washers engage the pins to allow adjacent modules to be aligned  while  allowing  adjacent  modules  to  deflect vertically  relative  to  each  other  in  an  unrestricted fashion.

IPC: E21B43/27
Filed: 1991-03-11
Abstract: A complexor and method of use are shown for providing controlled delay of the cross-linking reaction in an aqueous well fracturing fluid. A base fluid is first prepared by blending together an aqueous fluid and a hydratable polymer which is capable of gelling in the presence of borate ions.      The complexor is prepared by mixing a cross-linking additive capable of furnishing borate ions in solution with a delay additive. The delay additive is effective, within a selected pH range, to chemically bond with both boric acid and the borate ions produced by the cross-linking additive to thereby limit the number of borate ions initially available in solution for subsequent cross-linking of the hydratable polysaccharide. The subsequent rate of cross-linking of the polysaccharide can be controlled by adjusting the pH of the complexor solution.

Title: Apparatus and method for fabrication of metallic fibers having a small cross section
Inventor: STROM-OLSEN JOHN O
IPC: B22D11/06
Filed: 1991-07-03
Abstract: The instant invention is concerned with the casting of metal fibers, preferably ferrous fibers, by the melt extraction technique. The metal to be cast as a fiber is in the form of a rod which is brought into contact with a spinning wheel having a tapered perimeter. The rod is heated by electromagnetic induction by a specially designed, slightly curved spiral coil. The coil is shaped to focus the heat at, or close to, the tip of the rod so to induce a meniscus. The rod is fed the through an opening in a guide that acts as a heat sink to carry away excess heat and prevent the rod from melting except at its tip. The spinning wheel is placed in contact with the melted portion of the rod and forms the fibers as it is rotated.
