Title: Self-attaching fastening element and method of attachment
Inventor: LADOUCEUR HAROLD A
IPC: F16B13/00
Filed: 1992-10-29
Abstract: A self-attaching fastening element, such as a nut fastener, having a body portion and an integral annular riveting barrel portion.      The body portion includes axial grooves and, in the preferred embodiment of the nut-type fastener, the body portion includes a radial flange and the grooves extend radially from the body portion into the flange portion. In the most preferred embodiment, the body portion is polygonal and the axial grooves are located in the juncture of adjacent flat surfaces. The method of attaching the self-attaching fastening element of this invention to a panel includes forming an opening in the panel coaxially aligned with the barrel portion having a diameter less than the barrel portion, driving the barrel portion into the panel, thereby drawing a cone-shaped portion in the panel receiving the body portion, driving the body portion into the cone-shaped panel portion, deforming the panel portion into the body portion and the axial grooves. The free end of the barrel portion may be simultaneously deformed radially to form a mechanical interlock with the panel. Where the body portion includes a radial flange, the flange is driven into the panel and the panel is driven into the radial grooves, preventing relative rotation of the fastening element in the panel.

Filed: 1992-11-16
Abstract: ABSTRACT OF THE DISCLOSURE                MARINE MOORING SWIVEL FITTING       A marine mooring swivel fitting for connection into a mooring line is a generally dumbbell-shaped element having a relatively slender elongate neck with outward enlargements at the opposite ends of the neck respectively and a mooring line attach-ment on at least one end of the element.  In use the attachment may connect the fitting in the mooring line, the slender elongate neck being adapted laterally to receive swivelly therearound one or more conventional shackles.  Such a shackle, depending on whether the swivel is at the upper or lower end of the mooring line, may be secured to a pendant made fast to a marine craft on the surface or secured to an anchoring device.  The enlargements, larger than the opening in the shackle, serve to limit the longi-tudinal movement of the shackle on the element without limiting rotational movement of the shackle around the element.

Inventor: ROBERTS ROBERT F
IPC: C08J7/043
Filed: 1993-03-04
Abstract: ABSTRACT OF DISCLOSURE RUBBER ARTICLE HAVING PROTECTIVE COATING      A polymeric article which is subject to attack by oxygen ozone and/or ultraviolet light is coated with a thin coating of a polymer which is resistant to oxygen, ozone and W light.  It protects the article from cracking or degradation due to any of these causes.  The uncoated article serves as a substrate. The substrate may be any polymer which is subject to attach by oxygen, ozone and/or ultraviolet light.  A preferred coating is cured from a highly saturated polymer having only a small amount of unsaturation, as for example, hydrogenated nitrile rubber (HNBR, or hydrogenated nitrile/butadiene copolymer), highly saturated styrene/butadiene copolymer, hydrogenated polybutadiene, or hydrogenated styrene/vinylpyridine/ butadiene terpolymer.  The hydrogenated or highly saturated polymer of the coating is obtained by hydrogenating an unsaturated polymer which is a polymer of 1,3-butadiene (5-100% by weight) and optionally one or more monoethylenically unsaturated polymers (0-95% by weight).  The cured coatings are typically elastomeric.  The coating is applied as an uncured highly saturated polymer latex, which is dried and cured in place on the substrate to yield the desired coated article.  The thickness of the coating may be about 0.5 mil (0.0005 inch) up to approximately 10 mils (0.01 inch).

Patent CA-2095142-A1 (CA)
Title: Bulk-material reactor
Inventor: RITTER JUERGEN
IPC: B01J8/12
Filed: 1992-08-26
Abstract: ABSTRACT OF THE DISCLOSURE           Lateral  vibrations  of  drillstring  bottom  hole assemblies are confirmed by sensing longitudinal and torsional accelerations or displacements of the drillstring at or near its top end during rotation and determining the lateral critical speed and displacement of the drillstring from the mode shape of the bottom hole assembly which occurs during forward synchronous whirl and longitudinal shortening of the bottom hole assembly resulting from such whirl.  Lateral motion of the bottom hole assembly, while drilling, is estimated based on longitudinal and torsional measurements at the top of the drillstring.  Radial displacement of the bottom hole assembly due to impacting of the borehole wall imparts a torsional impulse which, together with considerable radial motion, is repeated each revolution.  The lateral or radial motion causes a small axial motion to develop in the bottom hole assembly which results in an axial force on and axial shortening of the drillstring which varies once per revolution.

Title: Process for the separation of catalyst-free working solution from the hydrogenation circuit of the anthraquinone process for the production of hydrogen peroxide
Inventor: EICKHOFF HUBERT
IPC: B01D71/00
Filed: 1993-05-21
Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to a process for the separation of catalyst-free working solution from working solution containing palladium black from the hydrogenation circuit of the anthraquinone process for the production of hydrogen peroxide.  The problem addressed by the invention was to improve the separation of a catalyst-free working solution from the hydrogenation circuit containing Pd black, which was previously carried out using filter candles, in order to reduce the process costs.  This problem is solved by the use of a micro-filter operating on the crossflow principle with a filter membrane of ceramic material, more particularly .alpha.-aluminium oxide, or polyolefin with an average pore diameter of 0.1 to 3.0 µm.  The crossflow rate is generally 0.5 to 5 m/sec.

Abstract: Hot raw fuel gas is produced by the partial oxidation of liquid or gaseous hydrocarbonaceous fuel or an aqueous slurry of solid carbonaceous fuel with substantially pure oxygen. The raw fuel gas is cleaned, cooled in a plurality of indirect heat exchangers, and purified to produce clean sulfur-free fuel gas.     Water is the coolant in one of said indirect heat exchangers and is thereby heated. Dry nitrogen gas is humidified with the warm water and the humidified nitrogen gas is separately introduced into the combustor of a combustion turbine. The clean sulfur-free fuel gas is passed in indirect heat exchange with the raw fuel gas, expanded to reduce its temperature and pressure, and separately introduced into the combustor where it is burned with air while in the presence of the water humidified nitrogen gas. Flue gas containing water humidified nitrogen gas and a substantially reduced amount of NO x gases is produced and passed through a power-producing expansion turbine as the working fluid. Increased power and efficiency are thereby obtained without polluting the atmosphere.
