Title: Method for producing efflorescence resistant coating on cementitious substrate
Inventor: HSU OSCAR HSIEN-HSIANG
IPC: C09D7/12
Filed: 1996-07-08
Granted: 1998-12-17
Abstract: The present invention is directed to producing an efflorescence resistant sealer coating on a cementitious substrate, such as, a roof tile. A foamed layer of an efflorescence resistant coating composition is preferably applied on the surface of a wet cementitious substrate. The wet cementitious substrate is then hydrated to produce the cementitious substrate having the efflorescence resistant coating thereon. If desired, the efflorescence resistant coating composition is provided with a pigment to produce a pigmented efflorescence resistant coating on the cementitious substrate or a clear efflorescence resistant coating of the present invention may be applied over pigmented cementitious substrate. The efflorescence resistant coating produced in accordance with the process of the present invention substantially reduces the formation of esthetically unpleasant efflorescent layer on cementitious substrate surfaces.

Granted: 1984-01-12
Abstract: An economic route to transport fuels from low grade feedstocks containing organic polycyclic components and mineral and/or metallic components comprises separating the feedstock into (a) a residue containing fuel values and substantially all of the mineral and metallic components and (b) a liquid hydrocarbon fraction; hydrogenating the liquid hydrocarbon fraction; providing hydrogen forthe hydrogenation by steam reforming methane-containing gas recovered from the hydrogenated material; and providing the heat for the steam reforming by immersing the reformer reactor tubes in a fluidised bed heated by combustion of residue from the separation step. If the fluidised bed is pressurised, the process can be made substantially self-contained with all the heat and ' power requirements for steam generation and feedstock compression for hydrogenation and steam reforming being recovered from the flue gas.

Title: Polytetraalkylammonium and polytrialkylamine containing ligands bonded to inorganic supports and processes of using the same for removing and concentrating desired ions from solution
Inventor: BRUENING RON
IPC: B01J20/26
Filed: 1991-09-30
Granted: 1994-03-10
Abstract: A method for the removal and concentration of desired ions from a source solution which may contain larger concentrations of other ions including H<+> comprises bringing the source solution into contact with a compound comprising a polytetraalkylammonium and/or polytrialkylamine containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The polytetraalkylammonium and/or polytrialkylamine portion(s) of the compound has an affinity for the desired ions to forma complex thereby removing the desired ions from the source solution. The desired ions are removed from the compound by contacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired ions than does the polytetraalkylammonium and/or polytrialkylamine ligand portion of the compound. The concentrated ions thus removed may be recovered by known methods. The process is useful in removing desired or unwanted ions from water streams and in the treatment of waste streams. The invention is also drawn to the polytetraalkylammonium and polytrialkylamine containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material.

Abstract: PURPOSE:To prevent soldering from becoming brittle by using solder grains or solder pieces coated with inert and insulating coil, with kinematic viscosity 10-100,000 cst, when a semiconductor pellet is fixed on a stem substrate. CONSTITUTION:Many solder balls 7 are put into insulating oil tank 9 filled with inert, insulating oil, with kinematic viscosity 10 to 100,000cst., and the surface of solder balls 7 is covered with insulating oil 8. On stem substrate 12, heated to 250- 350 deg.C by heater 11, which also functions as a heat discharge plate, solder balls are dropped by using an injector, and at the same time, the surface of molten solder 7' is covered with floating insulating oil 8'. In this way, the solder is prevented from becoming brittle. By using a supersonic oscillation horn, oil 8' and solder 7' are removed, and here semiconductor pellet 15 is mounted and cooled, and thereby pellet 15 and substrate 12 are bonded together. By this, soldering under a fixed specification can be rendered feasible.

Abstract: The present invention relates to DNA compounds which encode human protein C activity. A variety of eukaryotic and prokaryotic recombinant DNA expression vectors have been constructed that comprise the novel protein C activity-encoding DNA and drive expression of protein C activity when transformed into an appropriate host cell. The novel expression vectors can be used to produce protein C derivatives, such as non- carboxylated, non-glycosylatedd, or non-hydroxylated protein C, and to produce protein C precursors, such as nascent or zymogen protein C, and to produce subfragments of protein C, such as active or inactive light and heavy chain. The recombinant-produced protein C activity is useful in the treatment and prevention of a variety of vascular disorders.
