Abstract: A ball retreiving assembly includes a housing, an ejection member and a cup member. The housing has a first end, a second end and a passageway extending between the first end and the second end. The ejection member is movably disposed within the passageway of the housing. The cup member is operationally connected to the housing and the ejection member, the cup member sized and dimensioned to receive a ball.

Abstract: The present invention is directed to a stable fluorocarbon emulsion having a continuous aqueous phase and discontinuous fluorocarbon phase comprising two fluorocarbons and surprisingly demonstrates that perfluorodecyl bromide is as effective in stabilizing perfluorooctyl bromide emulsions of certain concentrations than much more highly concentrated perfluorooctyl bromide/perfluorodecyl bromide emulsions without the significant problems experienced in higher concentrated emulsions such as longer organ retention times, formation of PFDB crystals, larger emulsion particles, manufacturing problems and inability of repeat dosing inherent with higher concentrations of perfluorodecyl bromide.

Abstract: Storage stable fluorocarbon emulsions having a continuous aqueous phase and a discontinuous fluorocarbon phase, in which the fluorocarbon phase comprises a major amount of a first fluorocarbon or fluorocarbon mixture, and a minor amount of a second fluorocarbon or fluorocarbon mixture, in which the second fluorocarbon has a molecular weight greater than that of the first fluorocarbon and the second fluorocarbon includes a lipophilic moiety in its structure, whereby the second fluorocarbon serves to promote particle size stability in the emulsion while simultaneously providing favorably short organ retention times when administered to animals in vivo.

Abstract: A method of attaching a semiconductor chip to a mounting surface is disclosed. A solder barrier is applied to the mounting surface, and a preform of solder is located within the solder barrier. The preform is heated and then cooled in a vacuum to preflow the solder and secure the solder to the mounting surface substantially without voids. The semiconductor chip is then placed over the preflowed solder, which is reheated and then recooled in a vacuum to secure the chip to the mounting surface.
