    摘要： An improved process for the preparation of poly(alkylene carbonate) polymer by the reaction of alkylene oxide with carbon dioxide and/or an alkylene carbonate at an elevated temperature and pressure is disclosed. The improvement comprises conducting said reaction in the presence of a catalyst mixture comprising an alkaline catalyst and a stannate compound.

    摘要： A foldable carrying case is described that has an integrated one-piece body of hingeably connected panels, and flexible gussets hingeably connected to the panels. The body is further provided with releasable fasteners. The body converts from a plane configuration to a container configuration, and vice versa. The container configuration is formed by folding the panels and the gussets, and the panels and gussets are connected by the releasable fasteners to prevent the container from unfolding. Also described is a method for making and using such a foldable carrying case. Also described is a kit including such a foldable carrying case and at least one storage container.

    摘要： The apparatus treats storm water and includes a cylindrical basket that has a housing with a circumferentially extending air slot near the base of the housing. The basket contains an annular bed of absorbent material surrounded by a filter cartridge. Water flows radially inward through the filter and the bed into a cylindrical inner drainage space which has an outlet at its lower end, covered by a float valve. The drainage space is also in fluid communication with a one-way valve that allows air to pass from the housing into the environment. During operation, the float valve lifts when the water level rises and air is expelled from the drainage space through the one-way valve. As a result, water is continuously siphoned through the basket apparatus. When the water level drops, air enters through the air inlet slot of the housing and rises in turbulent fashion along the filter, scouring the filter and dislodging particulates. As a result, the filter is cleaned and the infiltration capacity of the basket filter is maintained.
