Abstract: A test system for testing the efficiency of blood oxygenators. The system includes a deoxygenator having a mixing section, a defoaming section and a collection section. Blood and deoxygenating gas are supplied to the mixing section. Mixed blood and gas exiting the mixing section enters the defoaming section where the mixture is defoamed. A portion of the deoxygenated and defoamed blood is directed to the oxygenator under test and the remainder is directed to an overflow reservoir. Blood exiting both the oxygenator and the reservoir is recirculated to the mixing section of the deoxygenator. Test sites are provided immediately upstream and downstream of the oxygenator under test so that the condition of the blood can be checked at both points and the efficiency of the oxygenator determined.The system provides for the precise control of the condition of the blood exiting the deoxygenator.

Abstract: Coke is produced with high yield and low sulfur by heating and drying ground coking coal at 200.degree. to 300.degree. C. for 15 to 120 minutes in air, and then heating in two semicoking stages in nitrogen in fluidized bed reactors. The first semicoking stage is 400.degree. to 600.degree. C. for 10 to 60 minutes while the second is 800.degree. to 1,100.degree. C. for 10 to 60 minutes. Tar is condensed from the offgases of the first semicoking stage and the residual gas is divided and 15 to 95% recycled to the first semicoking reactor. Similarly, 15 to 95% of the offgases from the second semicoking reactor is recycled. The condensed tar is fed to the final coke-forming operation.

Abstract: An apparatus for spraying plastic foam includes two containers respectively adapted to hold a solution of a urea-formaldehyde precondensate in a first aqueous medium and a second aqueous medium including a catalyst which causes rapid hardening of the precondensate when the two aqueous media are mixed. A foaming chamber communicates with a source of compressed air and with one of the containers for dispersing the gas in the corresponding medium and for thereby forming a foam. A first conduit connects the foaming chamber to a mixing chamber, and a second conduit connects the other container to the mixing chamber. A third conduit leads outward of the mixing chamber and terminates in a nozzle orifice normally open to the atmosphere. The compressed air is used for conveying the foam and the medium in the other container to the mixing chamber for continuously mixing the contents of the mixing chamber and for conveying the resulting mixture outward through the nozzle orifice when the latter is open.
