Abstract: Abstract of the disclosure:    The invention provides a process for the regeneration of dilute sulfuric acid containing organic impurities and possibly also inorganic salt in several steps.  In the first step, the dilute acid is concentrated by indirect heat exchange with the vapors of the second step, and in the second step it is concen-trated by direct           heat exchange with a countercurrent mixture of steam and acid vapors coming  from a third step.  In this third step, the acid discharged from the second step is mixed in direct heat exchange with superheated steam.  The re-generated sulfuric acid is separated from this mixture and the remaining steam/vapor mixture is forwarded to the second step. In the case where the dilute acid contains organic substances, an oxidant is added in at least one of these process steps.

Abstract: ARRANGEMENT FOR INTRAVENOUS ADMINISTRATION                  OR THE LIKE                 ABSTRACT OF THE DISCLOSURE The arrangement comprises a passageway for receiving liquid for intra-venous administration (IV) or the like. A hydrophilic microporous mem-brane having a first pore size is disposed in the passageway at a first point so that all liquid passes through the microporous membrane at said first point. A microporous filter is disposed below the membrane in the passage-way to filter all liquid passing through the passageway at the second point.          The membrane has a bubble point high enough to withstand the expected head of liquid below it (the gravity head of the IV set). Should liquid from the-source as it proceeds through the passageway from the microporous membrane to the filter be exhausted, then when air or gas reaches the mem-brane the flow of liquid is stopped because the upper, microporous mem-brane acts as an automatic shut-off valve. Air does not pass through the wet hydrophilic microporous membrane as long as the pressure does not exceed its bubble point. Accordingly there is no danger of air arriving at or passing through the microporous membrane to air-lock the lower passage way. A bellows drip chamber may be arranged in the passageway immediately below the membrane and may act as a drip chamber.  A further embodiment comprises such a bellows drip chamber arranged in the passageway below and immediately adjacent the microporous mem-brane, and a branch in the passageway in the section between the drip chamber and the hydrophilic filter is used for the application of a secondary or auxiliary solution. In such a case, if the source of the secondary solu-tion is higher than the source of the primary solution, the secondary solu-tion will be preferentially administered. There will be no back-flow because air or gas in the bellows or drip chamber will act as an air lock and prevent the backward flow of liquid in the first passageway because air or gas can-not pass through the hydrophilic upper microporous membrane which is wet by the liquid above it.

Abstract: ABSTRACT   The invention relates to a pneumatically powered nut runner having an axial swivel interposed the housings of the air motor and gear reducer which permits radial repositioning of the gear reducer housing relative to the air motor housing.  A torque reaction bar is affixed to the gear reducer housing and is thus also radially repositionable relative to the air motor housing.  This repositioning capability facilitates adjustment of the reac-tion bar so that it contacts a bracing point without necessitating the radial repositioning of the air motor housing.  When torque is applied to a fastener, nearly all reaction torque is taken by the torque bar and none is transmitted to the operator.
