Title: Method and apparatus for treating liquid/gas mixtures
Inventor: HENRIKSEN NOROLF
IPC: C02F1/20
Filed: 1987-02-13
Granted: 1995-06-21
Abstract: Method and means for treating of and mass transfer in liquid/gas mixtures, especially removal of oxygen from seawater to be injected into deep structures to increase the production of underground hydrocarbon resources. The oxygen removal is performed by means of an inert stripping gas which is purified and regenerated before it is recirculated. 
<??>Liquid and gas is pumped in turbulent concurrent flow with the inert gas through one or more tubelike zones (2) to one or more separation zones (6) where gas and liquid are separated. The liquid is led to the next treatment stage, while the stripping gas is returned to the prior treatment stage. The liquid flow and the gas flow are pumped and controlled independently of each other, to allow optimal treatment conditions and correct amount of transported liquid to be obtained.

Title: Centrifugal concentrator
Inventor: MCALISTER STEVEN A
IPC: B04B1/12
Filed: 1988-01-13
Granted: 1991-10-19
Abstract: Prior centrifugal concentrators for concentrating precious minerals use annular ribs or baffles to trap the precious minerals. Sand or magnetite tends to pack against such ribs, reducing the effectiveness of these devices. In the present invention, the inner surface of the rotating drum (2) is free of obstacles, but forms three continuous zones, a migration zone (A), a retention zone (B) and a lip zone (C). The precious mineral is retained in the retention zone by centrifugal force and friction while the unwanted slurry flows over the retention zone and out of the drum (2).

Abstract: N-monosubstituted neoalkanamides of 11 to 14 carbon atoms wherein the substituent on the amide nitrogen is cyclic (aromatic or cycloaliphatic, such as aryl or cycloalkyl) and of at least five carbon atoms, have been discovered to be insect repellent, providing that any aromatic substituent is unsubstituted at the ortho position and that when the neoalkanoyl moiety is pivaloyl the total number of carbon atoms in the N-cyclic neoalkanamide is at least 12. Such neoalkanamides are useful as repellents against cockroaches, including American, German and Oriental cockroaches, and are also effective against mosquitoes (both Anopheles and Aedes), black flies and carpenter ants, and to some extent against deer ticks. They may be applied to areas, locations and items which are desirably to be kept free of such insects, with applications being direct or of solutions or emulsions thereof, preferably by spraying, or in detergent compositions or other products to be applied to such areas, etc. Because the described neoalkanamides are desirably substantive to surfaces and are usually in liquid state, they give long lasting repellency to such areas, etc., and tests have shown them to be sufficiently long lasting.

Title: Making method for coating steel sheet
Inventor: KIM HYONG-JUN
IPC: B05D7/14

Abstract: The method improves painting inferiority of the steel plate. The method coats the steel plate with lacqer after adding 0.05-2.0% surfactant to it. This mixture results in the reduction of surface tension to decrease the generation of eyeholls in coating. If the quantity of the added surfactant is below 0.05%, the effect of surfactant addition is little. And if over 2%, the coating efficiency gets worse to require some additional cost.
