  • Patent number: 8119096
    Abstract: Method for the production of a finely crystalline boehmite and application of said boehmite as flame retardant in plastics. The method involves mixing aluminum monohydrate with a boehmite crystal structure in water to form an aqueous dispersion of said aluminum monohydrate in said water, and then grinding the dispersion while maintaining the dispersion in a pH range of 2 to 4 and forming boehmite seed crystals. The boehmite seed crystals can then optionally be mixed with a hydrate and a basic aqueous solution to form a dispersion which may be heated to convert at least a substantial portion of the aluminum monohydrate to boehmite.

  • Patent number: 6087299
    Abstract: The present invention relates to silver-containing and optionally promoter-containing supported catalysts and catalyst intermediates, processes for their preparation and their use for preparing alkylene oxides by oxidation of alkenes with oxygen. The catalysts are prepared by treatment of a support with a lactic acid containing silver ions, nitrate ions and optionally promoter metal ions, drying, predecomposition in a virtually oxygen-free atmosphere and subsequent activation by heating in an oxygen-containing atmosphere while precisely controlling the temperature conditions and the feeding-in of oxygen. The catalyst intermediates obtainable by treatment, drying and only predecomposition can be activated in a temporally and physically separate process step to form the actual catalysts. Suitable promoters are alkaline earth metal compounds and/or alkali metal compounds. High activities and high selectivities are achieved when using the catalysts of the invention for preparing alkylene oxides.

  • Patent number: 5238348
    Abstract: Parking garage hoist translates on a central `main` aisle driven by hydraulic translation motor and raises hoist car driven by hydraulic translation motor. Both motors are mounted near the base of the hoist and power for the hydraulic motors is derived from overhead electrical rails and power pick-up with the picked up power converted to hydraulic power. A transverse aisle may be provided to house a hoist for maintenance while another hoist travels on the main aisle. An extension aisle may be provided to house a hoist while another hoist travels on the main aisle.
