Abstract: Cigarette filters which comprise hydroentangled lyocell staple fibers are disclosed. High filter efficiencies, good taste properties, good resistance to staining, good physical resilience and good air flow characteristics are observed when cigarettes containing such filters are smoked.

Abstract: This invention provides smoking compositions which contain a novel .beta.-hydroxycarboxylate flavorant-release additive. Under cigarette smoking conditions, a combustible filler and/or paper wrapper additive such as calcium bis(2,2-diethyl-3-hydroxy-4-phenylmethylenedecanoate) pyrolyzes and releases .alpha.-hexylcinnamaldehyde as a volatile flavorant component of the cigarette smoke.

Abstract: A process for the production of 4,6-dimethyl-7-hydroxynonan-3-one of specific stereochemistry is disclosed. The process results in an active (+)-serricornin.

Abstract: A spring clip, particularly for use as a peg for suspending clothes from a crossbar of a hanger, has a bar-engagement clip lying between a fulcrum for pivoting movement of a pair of levers and a nip formed by one end of the pair of levers. A U-shaped spring urging those ends together has arms the outer surfaces of which lie flush with outer surfaces of the levers to form substantially flat side surfaces. The clip is integral with the spring. The ends of the arms of the spring may engage the levers by a snap-fit. The flat side surfaces may be used for the adhesive attachment of alternative mounting means for the clip, such as a double-sided adhesive pad.

Abstract: A sorting apparatus arranged to receive a stream of sheets for collating the same into booklets having a rotary sorter comprised of a plurality of bins each of which includes a sheet clamping device to hold sheets in registered orientation in the bins. Control means cooperate with the clamping means to release the sheets at a loading station to permit egress of the sheets one at a time into the bins as the sorter rotates, and to release the clamping devices at an unloading station to permit removal of the completed booklets.

Abstract: This invention provides a process for the conversion of an alicyclic .alpha.,.beta.-olefinically unsaturated ketone compound to an acyclic oxocarboxylic acid product which contains at least one less carbon atom per molecule than the ketone starting material.The conversion involves ozonation of the alicyclic .alpha.,.beta.-olefinically unsaturated ketone in an aqueous alcohol reaction medium, followed by a heating step.

Abstract: This invention provides a process for the preparation of cotinine and nicotine analogs containing substituents on pyrrolidinone/pyrrolidine ring at the 3' position of cotinine and at the 4' and 5' position of nicotine.The process proceeds via a first step preparation of a cotinine intermediate which is represented by the formula: ##STR1## wherein M is an alkali metal cation.

Abstract: A finishing station is disclosed as having a rotary sorter arranged to receive a stream of sheets at a loading station and to collate them into booklets or copy sets. An adhesive binder is positioned at an unloading station and is arranged for movement toward and away from the edges of the booklets while still in the sorter bins of the sorter. When moved toward the edges of the booklets, an applicator roller in the binder is arranged to apply adhesive material to the edges in timed sequence relative to sheet loading.

Abstract: A copying machine/finisher system is disclosed as having a rotary sorter arranged to receive a stream of copy sheets produced by a processor in conjunction with an automatic document handling apparatus of the type which produces multiple copies of a document sheet placed at an exposure station. The sorter collates the stream into booklets as the sorter is rotated in an indexing manner. An adhesive binder and a stapler are selectively positioned to effect binding while the booklets are still in the bins of the sorter. Binding is effected in timed relationship with sheets still entering the sorter. The sorter/finishing apparatus may also be a stand alone system.

Abstract: This invention provides smoking compositions which contain a diacylpiperazine additive such as 1,4-(2-methylpropionyl)-2,3,5,6-tetramethylpiperazine: ##STR1## The preferred diacylpiperazine additives impart enhanced flavor response and smoothness.

Abstract: Novel azetidine, and particularly 2-pyridyl-azetidine, compounds are disclosed. These compounds are produced from amino-esters by a sequence comprising conversion to the sulfonamide, reduction of the ester to the alcohol, sulfonation of the resultant alcohol and cylization to the N-sulfonylazetidine. This azetidine compound may then be transformed, as desired, to various N-derivatives by substitution of hydrogen or other univalent organic groups on the secondary amine of the azetidine ring.

Abstract: Novel azetidine, and particularly 3-pyridyl-azetidine, compounds are disclosed. These compounds are produced from .gamma.-amino alcohols by a sequence comprising disulfonation to produce the sulfonamido-alkylsulfonate and then cyclization to the N-sulfonylazetidine. These azetidine compounds may then be transformed, as desired, to various N-derivatives by substitution of hydrogen or other univalent organic groups on the secondary amine of the azetidine ring.
