摘要： This invention provides an improved negative-working or positive-working, single sheet color proofing method which can accurately reproduce images by using colored, photosensitive layers on substrates which are then overcoated with partially developable adhesive layers. The final construction is useful in predicting the image quality from a lithographic printing process. The partial removal of the adhesive layers cleans out any background stain which may remain from the incomplete removal of the photosensitive layer.

摘要： A unique polymer was synthesized via copolymerization of vinylpyridine and acetoxystyrene under radical-initiated conditions followed by acidic or basic hydrolysis of the acetoxy group to afford the corresponding hydroxy group. The built-in acid-base dual functionality (phenolic and pyridyl units) in this polymer backbone gives rise to its unique solubility properties over a wide pH range in both aqueous and non-aqueous media. Due to its amphoteric nature, this polymer finds application as an anti-stat, viscosity modifier, and/or ion-exchange resin.

摘要： A molded plastics cassette case for rotatably accommodating a flexible magnetic disc (preferably a nominal 3.5 inch diameter microdisc) includes at least one, and preferably several, drag finger integrally molded therewith. The drag finger has a base end which is structurally unitary with the cassette case, and a free terminal end, opposite to the base end, which imparts frictional drag resistance to the central hub of the flexible magnetic disc. In this manner, more reliable rotational velocity of the spinning magnetic disc may be achieved without the need for separate liner and lifter structures associated with conventional microdisc cassettes, thereby simplifying cassette construction and assembly.

摘要： A new monomer is used to prepare homo or copolymers containing blocked imide groups which are characterized by deblocking in two stages, first when acid catalyzed and thereafter in aqueous alkaline solutions. Such polymers are, therefore, especially useful in formulating positive photoresist compositions. The polymers are combined with a latent photoacid, which when exposed to actinic radiation removes the acid sensitive blocking moiety, preferably an acetal or ketal group, leaving a methylol group or substituted methylol group remaining attached to the nitrogen atom, which groups are subsequently removed by exposure to aqueous alkaline developing solutions, leaving only imide groups. ##STR1## The new monomer is a derivative of maleimide in which the imide hydrogen has been replaced with a methylol group, which is subsequently reacted to form an acetal or ketal. Preferred monomers include N-(2,4-dioxa-3,3-dimethylpentyl)-2H,5H-2,5-dioxopyrrole and related compounds.

摘要： Modules for use in fluid separations, especially contained liquid membrane separations, exhibit minimal effective membrane thickness. The modules have a module case and bundle of a dense plurality of hollow fiber membranes contained in the case. One set of the fiber membranes in the bundle constitutes feed-fibers while another set of the fiber membranes in the bundle constitutes strip-fibers for use in contained liquid membrane separations. The feed-fibers and strip-fibers are disposed within the elongate module case in opposite generally wave-like paths such that the feed-fibers and strip-fibers converge at generally lengthwise-separated crossing regions within the module. This disposition of the feed-fibers and the strip-fibers minimizes the effective membrane thickness value of the module as compared to conventional contained liquid membrane modules thereby enhancing the efficacy of fluid separations.

摘要： A method is provided for the preparation of ibuprofen by carbonylating 1-(4'-isobutylphenyl)ethanol (IBPE) with carbon monoxide comprising initially a reaction mixture comprising IBPE, ibuprofen and a catalyst for the carbonylation with carbon monoxide under conditions to initiate the reaction, and continuing to feed carbon monoxide to the composition to produce the desired yield of ibuprofen. Preferably the catalyst comprises palladium and a monodentate phosphine ligand. The presence of ibuprofen in the feed composition when the reaction is initiated with CO makes it possible to obtain high selectivities to ibuprofen with substantially complete conversion of IBPE at much shorter reaction times than if no ibuprofen is present initially.
