Abstract: Hydrogenation catalyst and a process for producing gamma-butyrolactone by hydrogenating a feed compound -- selected from the group consisting of maleic acid, succinic acid, maleic anhydride, succinic anhydride, and mixtures of any of the foregoing -- in the vapor phase, in the presence of said catalyst, which is a highly selective elemental Cu-Pd or Cu-Pt catalyst, in order to produce high yields of gamma-butyrolactone and minimize the formation of by-products.

Abstract: A portable microform reader is provided with a microform carrier and a projection system for projecting an enlarged real image of the information carried on a portion of the microform onto a viewing screen. A binocular magnifying system is arranged for viewing the screen and for further enlarging the image thereon to produce a virtual image of acceptable reading size. The projection system comprises a source of illumination, a condenser lens, and a projection lens for projecting an image of the information carried on the microform onto the screen. The magnifying system may consist of appropriate binocular lenses where such lenses, in combination with prismatic converging means, produce the desired magnification. Beam splitting means may alternately be provided to eliminate the need for prismatic converging means, and a mirror arrangement may be provided to "fold" the projected beams for further limiting the size of the reader.

The invention also comprises the method of utilizing the etchant composition and the improved precision device produced thereby.

Abstract: A derivative of paraphenylenediamine, for use as a color developer, having a primary amino group available for oxidative coupling, and a carboxy group bound to the benzene ring to provide the compound with the required stability to enable the compound to be incorporated into a photographic film, the compound being non-diffusible during development of the photographic film in an alkaline processing solution.

Abstract: A diffusion transfer photographic element containing a lipophilic, non-diffusing color former in a silver halide emulsion layer, or in a layer adjacent thereto, is developed by using a water- and alkali-soluble color developer capable of coupling with the color former to form a diffusible coupled product, the color developer being coated with the silver halide emulsion layer or in any layer of the photographic element or being in an alkaline developing solution.

Abstract: A phenyl amino compound having a tertiary amino group contain one or two N-bonded --C.sub.2 H.sub.4 CONHC(CH.sub.3).sub.2 CH.sub.2 COCH.sub.3 moieties; said tertiary amino group being bonded through the nitrogen atom to the phenyl group.

Abstract: Compounds of the formula: ##STR1## wherein R is halogen or trifluoromethyl, n is 0 to 5, and CD is the residue of a paraphenylenediamine color developer having a primary amino group available for oxidative coupling, the phenoxycarbonyl group being attached to the primary nitrogen atom of the paraphenylenediamine color developer, are used in a receiving sheet of a diffusion transfer photographic element for coupling with a color former to form a stable dye.

Abstract: A system for sustained release of phenolic material into a fluid from phenolic complexes of water-insoluble, but water-swellable crosslinked N-vinyllactam or N-alkyl-N-vinylamide polymers in the form of porous beads or granules. The complexes, which are particularly suited for use in situations wherein fluids containing phenolic materials in limited quantities are desired, and are provided by leaching a limited amount of phenolic material from the complex by contacting the porous granules in a container, such as in a canister or column which is used to treat liquids or water.
