Devices for holding beverage containers that can be used inside a vehicle or attached to a structure. In one example, a cup holder device for use in a vehicle may include an upper portion having a bottom surface, a peripheral rim offset from the bottom surface, and a side surface connecting the peripheral rim to the bottom surface. The peripheral rim defines an opening that is configured to receive a cup in the upper portion. A lower portion is coupled to the upper portion. The lower portion is configured to fit into a gap of an interior vehicle door, the impression typically formed by at least a first inside wall, a second inside wall, and an inside bottom surface. The lower portion may include a molded form configured to fit inside the impression of an interior vehicle door, or a spring-biased connector to attach to the impression.

Finger well insertable cup holder

A process for the polymerization of olefins is disclosed. A boraaryl catalyst precursor and an activator are used in the presence of a silane modifier. A low level of silane modifier enhances the activity of the catalyst.

Use of silanes to enhance activity in single-site polymerizations

A process for polymerizing propylene is disclosed. The process involves charging propylene and about 90 to 99% of an organoaluminum cocatalyst to a reactor and heating this mixture to at least about 50&deg; C. This is followed by addition of a premix of 1 to 10% of the organoaluminum cocatalyst with a magnesium halide-supported Ziegler-Natta catalyst. The temperature of the reaction mixture is maintained to produce a propylene polymer. The process gives improved catalyst activity.

Propylene polymerization process with enhanced catalyst activity

Supported heterometallocene catalysts wherein the support is a particulate polymeric material are provided. The catalysts have a transition metal complex containing at least one anionic, polymerization stable heteroatomic ligand associated with the transition metal and a boron activator compound deposited on the support. Polymeric supports used for the heterometallocene catalysts of the invention are homopolymers of ethylene and copolymers of ethylene and C,&agr;-olefins.

Supported olefin polymerization catalysts

A supported olefin polymerization catalyst system and a method of making it are disclosed. The catalyst system comprises: (a) a support chemically treated with an organoaluminum, organosilicon, organomagnesium, or organoboron compound; (b) a single-site catalyst that contains a polymerization-stable, heteroatomic ligand; and (c) an activator. Chemical treatment is a key to making supported heterometallocenes that have high activity and long shelf-lives, and can effectively incorporate comonomers.

A jigsaw puzzle includes outer straight edge pieces forming a rectangular puzzle perimeter; a number of interior straight edge pieces suggesting an interior rectangle and increasing the proportion of the number of straight edge pieces to the total number of pieces in the puzzle; and a number of joiner pieces, some of the joiner pieces crossing the bounary of the interior polygon, and others of the joiner pieces at positions remote from the boundary.
