Abstract: ABSTRACT     A novel process for extracting and recovering acetone in waste filter pads of cellulose fiber is disclosed. The process is fast, economical and produces high yields of recovered acetone. Spent or waste filter pads containing recoverable acetone are admixed and dissolved in acetone and water so as to form a suspension to solids in a liquid.  The admixture is thereafter subjected to distillation with the acetone being recovered in the distillate.  The preferred ratio to acetone in the waste filter pad to acetone and water admixed therewith is from about 1:4.1:3.3 to about 1:2.5:2.0 by weight.  The acetone may be added first or concurrently with the water addition.

Abstract: ABSTRACT:     Electrical connector assembly comprises a housing having a plurality of cavities therethrough and a retainer having a like plurality of passages therethrough, said housing and retainer being latchably matable so that said cavities and passages are coaxially aligned. Retainer has contact engaging means formed as sets of spring fingers radially arranged about respective passages and extending from the forward face of the retainer to distal ends of the fingers. Each set of fingers defines a first diameter at the forward face and a second smaller diameter toward the distal ends, the fingers spreading apart resiliently as a contact inserted through the passage reaches the smaller diameter, the fingers returning so that the distal ends engage a shoulder on the contact when the contact is fully inserted. The fingers and cavities are profiled so that the distal ends will stub against the rearward face of the housing rather than entering cavities when the fingers are spread apart, thereby precluding mating of the housing and retainer when contacts are not fully seated .

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an automatic release mechanism for a cultivator which provides good resistance to release of the shank holder and which upon release causes the shank holder to rise to a good height to clear obstacles encountered during operation of the cultivator.  The shank holder is mounted so as to pivot about an axis and is retained in the working position by a pair of springs under tension, the forward end of the springs being mounted in front of and beneath the position of the pivot axis of the shank holder, and the moment arm of the springs is such that, as the shank holder pivots, the moment arm decreases resulting in the tangential force applied by the springs to the ground engaging tool about the pivot axis remaining substantially constant during pivoting of the shank holder to clear an obstacle.

Abstract: MONOCLONAL ANTIBODIES TO PEPTIDOGLYCAN    AND METHODS OF PREPARING SAME                              Abstract Several novel hybridoma cell lines, ATCC #HB-8510, 8511, 8512, 8513, 8514, 8515, 8516, and 8517 produce mono-clonal antibody to an antigen, peptidoglycan, which is a normal structural component of nearly all true bacteria. Each antibody reacts not only with peptidoglycan from the immunizing bacterial strain but also peptidoglycan from other strains.  Certain of the members of the hybridoma panel produce monoclonal antibody which reacts with pep-tidoglycan from substantially any peptidoglycan-possessing bacterium.  The hybridomas are formed by fusing spleen cells from immunized Balb/c mice with SP2/O-Ag14 myeloma cells.  Diagnostic and therapeutic uses of the monoclonal antibodies are provided.
