Abstract: Crosslinked copolymers of monomeric aminosaccharides such as aminoglycosidic antibiotics, e.g. neomycin, or of polymeric aminosaccharides, e.g., chitosan, with dialdehydes are useful antihypercholesterolemic agents due to their ability to bind with bile acids. These copolymers are insoluble in acidic solutions but are swellable to at least about 2.times. their original weight.

Abstract: Die attach pickup tools for relocating a flexible die attach. The pickup tools comprise a head portion connected to an end portion. The head portions have a face for contacting a die attach and at least one hole in the face. Passage means extend from the hole(s) through the tool for connection to a vacuum source.

Abstract: A process involving scanning an original linewise and determining the tonal value of each scan dot. Multiple scan dots are collected into a scan field. The average tonal value of each scan field is determined by averaging the tonal values of the scan dots of that scan field. The original is reproduced on a recording medium by individual recording dots that can take the tone value "print" or "no-print". Several recording dots correspond to a scan field of the original. The tone value of the scan field can be reproduced almost exactly on the average by printing a specific number of recording dots. The distribution of recording dots to be printed for a scan field is determined by subdivision of the scan field into the smallest subfields.

Abstract: The sutural material consists of a base from a bio-resolvable polymer and a layer of a copolymer of N-vinylpyrrolidone with an alkylacrylate and/or an alkylmethacrylate deposited onto the base and containing an antimicrobal preparation or a mixture of preparations and having the period of its biodestruction shorter than that of the base, the thickness of this layer being equal to 0.1 to 1.0 of the base thickness.

Abstract: Cognitive deficiencies and/or neurological function deficits and/or mood and/or mental disturbances are treated by the administration of 3,3-disubstituted indolines. The indolines have the formula: ##STR1## wherein: p is 0 or 1;Z is O or S;R is C.sub.1 -C.sub.10 alkyl, C.sub.3 -C.sub.8 cycloalkyl, 2-pyridyl, 3-pyridyl, 4-pyridyl or ##STR2## V, W, X, and Y independently are H, halo, C.sub.1 -C.sub.3 alkyl, OR.sup.1, NO.sub.2, CF.sub.3, CN or NR.sup.1 R.sup.2 ;R.sup.1 and R.sup.2 independently are H or C.sub.1 -C.sub.3 alkyl; ##STR3## independently are 6-membered heterocyclic aromatic rings containing at least one nitrogen atom as a part of the ring optionally substituted with one substituent selected from the group C.sub.1 -C.sub.3 alkyl, halo, OR.sup.1 or NR.sup.1 R.sup.2 ; oran N-oxide or pharmaceutically suitable acid addition salt thereof.

Abstract: A multi-row right-angle type header is mounted upon a printed circuit board and includes a series of leaf-type spring contacts positioned on opposite sides of the pin field and are designed to effect electrical connection with the conductive shroud of the connector telescopically received within the housing. The spring contacts each include respective tail portions that extend rearwardly of the housing and are connected to the printed circuit board in such a way that the adverse effects of electric fields is attenuated. In another form of the invention, a shield structure is connected to the tail portions of the spring contacts to provide an additional increment of shielding. The present invention advantageously provides for the shielding of the terminal leads of headers and connectors in the context of right-angle mountings so as to attenuate electric field radiation from and between the various circuits and attenuate the effect of external fields on those circuits in a cost-effective manner.
