Abstract: A cabinet that hangs on a wall and directs forces in such a manner so as to provide a stronger assembly. The cabinet includes a front frame, joinery, and a plurality of panels. The joinery attaches some of the plurality of panels to each other and to the front frame, and directs the forces from the some of the plurality of panels to the front frame so as to provide the stronger assembly.

Abstract: The present invention provides a highly selective catalytic cracking process for the conversion of feedstocks containing a predominant content of C.sub.10 and higher mixed olefins into C.sub.9 and lower olefin products at efficiencies of greater than 20%. said products further characterized in that the content C.sub.6 to C.sub.9 olefins is maximized while the content of C.sub.2 to C.sub.4 olefins is minimized. The process involves contacting an olefin feedstock mixture containing at least about 50 weight %, more preferably at least about 70 weight %, of C.sub.10 and higher olefins under cracking conditions with a catalyst selected from the group consisting of amorphous precipitated silica, selected crystalline silicates and aluminosilicates, namely beta, mordenite and ZSM-5 types, as well as ion exchanged or acid variants thereof. Cracking conditions include a temperature within the range of from about 250.degree. up to about 450.degree. C.

Abstract: There are disclosed catalysts and process for oligomerizing C.sub.3 -C.sub.12 olefins in the liquid phase at 50.degree. C.-150.degree. C. in the presence of a nickel containing zeolite catalyst, the zeolite being a Cs or Ba exchanged CSZ-1, high silica ultra-stable faujasite and zeolites isostructural with mazzite.

Abstract: A synthetic crystalline zeolite is provided characterized by having a composition, in terms of mole ratios of oxides, in the range:0.9 to 1.1 M.sub.2/n O:Al.sub.2 O.sub.3 :2.5 to 5.1 SiO.sub.2 :xH.sub.2 Owherein M is at least one exchangeable cation, n is the valence of M, and x is 0 to 6, and characterized by having a specified x-ray powder diffraction pattern. The zeolite may be prepared by crystallization from a reaction mixture of KOH (and optionally a minor amount of NaOH), water, a source of silica, and a source of alumina preferably derived from kaolin or halloysite. Most preferably, the source of alumina is metakaolin and the source of silica is potassium silicate.

Abstract: Apparatus for the cultchless cultivation of marine bivalve mollusks, e.g., oysters and clams, has a plurality of quadilrateral compartments connected together by a pair of longitudinal cords in the form of a continuous belt. In use of the apparatus, spat is placed in the culture chambers of the belt which then is immersed in an aquaculture plot and the spat is allowed to grow in such chambers. Later, portions of the belt are lifted out of the water while allowing the remainder of the belt to remain immersed and compartments in the withdrawn portion of the belt are cleaned and/or opened to process mollusks contained therein.

Abstract: Useful cracking catalysts and catalyst supports comprising silica supported on alumina are prepared by compositing particles of silica or silica precursor with particles of porous alumina and subjecting the resulting composite to high temperature steaming in a non-reducing environment at a temperature of at least about 500.degree. C. for a time sufficient to disperse at least a portion of the silica over the alumina surface. The silica wets, spreads out and reactions with the surface hydroxyul groups of the alumina. The supported silica on alumina composites that can be made from this process may exhibit properties of both bulk silica and bulk alumina at the same time, bulk silica and alumina whose exterior surface only has been modified with silica as wells as composites exhibiting surface properties different from both bulk silica and bulk alumina.

Abstract: A zeolite of the L type is prepared by an approximately stoichiometric process wherein the zeolite is crystallized from a reaction mixture aged at from 80.degree. to 260.degree. C. containing specified ranges of molar ratios of KOH (and optionally a minor amount of NaOH), water, potassium silicate, and a source of alumina preferably derived from kaolin or halloysite. Most preferably, the source of alumina is metakaolin.

C. containing water, a source of silica or germania, a source of alumina or gallia, a source of potassium (and optionally up to 40 mole percent of a source of sodium, based on total mole percent of potassium and sodium), and a salt of a tetraalkylammonium cation wherein at least two alkyl groups have more than one carbon atom. Most preferably the cation is tetraethylammonium cation.
