Abstract: ABSTRACT         A board to board interconnect assembly is installed between a first multilayer circuit board and a second multilayer circuit board.  The assembly is comprised of a first housing member carrying electrical contacts and a second housing member carrying electrical contacts which mateably engage with the contacts of the first housing member.  The first and second circuit boards have corresponding arrays of plated through apertures selectively connected to the circuit layers of the respective boards.  Socket carrying contacts are frictionally engaged in certain of the plated through conductive apertures of the first and second circuit boards to secure the first housing member to the first circuit board and the second housing member to the second circuit board.  Flex contacts are installed in conductive plated through apertures of the boards opposite each of the socket contacts and are frictionally engaged with the socket contacts.  The socket and flex contacts are frictionally coupled to elect-rically connect the circuit layers of the first circuit board with the circuit layers of the second circuit board in a direct vertical relation-ship.  The opposed first and second housing members support and position the contacts and serve as spacers between the circuit boards.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a process for separating and re-covering boric  acid from water containing solids which include boric acid and radionuclides.  In the first step, the water is separated from the solids by evaporation of the water at a temperature under 130°F.  In the second step,  an alcohol selected from the group consisting of methanol,  ethanol,  propanol,  isopropanol,  and mixtures thereof is added to the remaining solids in the amount of at least 1.4 times that  stoichiometrically required to react with the boric acid to form boron alkoxide and water to about 100 mole % in excess of stoichiometric.  In the third  step,  the  boron  alkoxide  is  separated from the remaining solids by evaporation of the boron alkoxide.  In the fourth step, water is added to the volatilized boron alkoxide to form boric acid and an alcohol.  And finally, the alcohol is separated from the boric acid by evapor-ating the alcohol.
