Abstract: A flow control system for an apparatus for radially expanding tubular members.

Abstract: A method of coupling a tubular member to a preexisting structure.

Abstract: A method of applying an axial force to an expansion cone.

Abstract: A method of operating an apparatus for radially expanding a tubular member.

Abstract: An apparatus for actuating an annular piston.

Abstract: An apparatus for radially expanding a tubular member.

Abstract: A filtration apparatus is described wherein entrained solids are removed from particulate-carrying fluid by filtration under vigorous conditions with filter tubes. The filter apparatus comprises a plurality of tiers of filters, each tier comprising filter tubes supported on a tube sheet. The apparatus also contains a tiered conical sluicing system to concentrate and centralize the particulates. The solids discharge from the filter tubes and pass through the sluicing system to exit the apparatus through particulate outlet means. The use of the apparatus is characterized by a reduced re-entrainment of particulates in the fluid leaving the apparatus.

Abstract: A process for the removal of HCN from gaseous streams is described, the process being characterized by reaction of the HCN in the gaseous stream with an ammonium polysulfide solution and formation of ammonium thiocyanate in solution, precipitation and removal of sulfur from the ammonium thiocyanate-containing solution, and hydrolysis of the ammonium thiocyanate. Provision is made for recycle of hydrolysis products.

Abstract: This invention relates to improvements in the execution of catalytic processes wherein chlorine in high state of purity is produced by reacting hydrogen chloride containing organic impurities with oxygen.

Abstract: A safety device for protecting a burner of a coal gasification plant against solid blockage. Solid blockage may occur in a burner of a coal gasification plant fed with a mixture of coal particles and fluid. In order to protect the burner against solid blockage a safety device is proposed which is arranged in the supply line to the burner. By means of this safety device relatively large pieces of solid material, which might cause blockage of the burner, can be eliminated from the mixture of coal particles and fluid supplied to the burner.

Abstract: A coated object is produced by flame spraying the object with a substantially molten polymeric material which comprises a blend containing polybutylene homopolymer or copolymer, an adhesion promoter and a nucleating agent.

Abstract: A super-toughened multiphase thermoplastic composition is provided by incorporating at least one functionalized, selectively hydrogenated alkenyl arene/conjugated diene block copolymer to which has been grafted an effective amount of carboxyl functional groups primarily in the alkenyl arene blocks thereof with an .alpha.-polyamide.
