A series of dihydrophenanthreneones and tetrahydrophenanthreneones are useful as inhibitors of 5.alpha.-reductase, and a series of hexahydrophenanthreneones are useful as intermediates for preparing such pharmaceuticals.

An apparatus is provided with a first plurality of input keys. Each of the first plurality of input keys is associated with at least one numeric value and at least one alphabetic value and arranged in a numeric and first alphabetic telephone keypad arrangement. The apparatus is also provided with a second plurality of input keys that are at least partially surrounding the first plurality of input keys. At least some of the second plurality of input keys are associated with at least one alphabeti...

An ion source modified by an additional electrode, designated as a scraper electrode, positioned between the anode and extractor electrode, having an aperture slightly less than the source plasma aperture, and adapted to carry a pre-determined voltage in reference to the anode. It has been found that the scraper electrode intercepts and removes ions at the periphery of the beam cross-sectional area and this is the region that contains ions that contribute most greatly to the increased emittance....

An optical element of reduced thickness is formed by a mosaic of discrete lens faces, the lens faces together deflecting light in a manner equivalent to a conventional optical element of much greater thickness. Process and apparatus for the production of the lens element is included.

An improved technique for imaging a multiplicity of planes of non-diffuse objects, including non-diffuse transparencies, with coherent illumination which utilizes a diffusion structure having a periodic phase thereacross.

A polydextrose having improved color, flavor and decreased reactivity toward food ingredients having amine functionality. The polydextrose comprises a water-soluble highly branched polydextrose having been prepared by a process which comprises melting dextrose in the presence of a food-acceptable acid catalyst. The improved polydextrose of this invention has substantially no reducing glucose groups. Another aspect of this invention is directed to a method of making the above-described improved p...

A carbonaceous material is controlled such that the amount of carbon is from 7 to 60 mass % based on the total amount of iron and Zn in a starting mixture comprising one or more of ducts containing iron oxide and Zn oxide and a binder in an amount to bond the dusts, and water is added to prepare green pellets incorporated with the carbonaceous material. Then, dry pellets prepared by drying the thus prepared green pellets into a reduction furnace, the dry pellets are heated by heat transfer, main...

A louver having a frame and a set of vanes mounted for pivotal movement about axes of rotation characterized by a rack and pinion operating the vanes, the rack being affixed to a plurality of co-engaging members that snap together to encompass a horizontal vane in the louver to facilitate assembly. In another aspect, the louver is characterized by the vanes having pins, or stub shafts, disposed in notches along at least one side of the frame and a snap-on strip for that side of the frame to hold...
