A dual reactor solution process gives high density polyethylene compositions containing a first ethylene copolymer and a second ethylene copolymer and which have good processability, toughness, and environmental stress crack resistance combined with good organoleptic properties. The polyethylene compositions are suitable for compression molding or injection molding applications and are particularly useful in the manufacture of caps and closures for bottles.

A plastic may be selected for a thin web application by finite element analysis of the part including the properties, including Poission's ratio of potential polymers from which the part may be made and subjecting the computer model of the part to loads to determine the deflection of the part under a specified series of loads or when the part breaks or subjecting the part to a number of use cycles to determine when the part fails. The process is iteratively repeated for each plastic and the results are compared to select a preferred plastic for the part.

Method of selecting a plastic

An interactive sports training device has a plurality of light sources, multiple sensor means and a processor to facilitate the manoeuvring, passing and shooting of an object. Each sensor means is associated with one of the plurality of light sources, the sensor means being adapted to be triggered when an object is brought into close proximity with an activated light source. A processor means is coupled to the light sources and sensor means and is provided with at least one training program, and the processor means controls activation of the light sources according to at least one training program. When an object is placed in close proximity to an activated light source, the sensor communicates with the processor to deactivate the activated light source and to activate another light source in accordance with a training program. In use, it provides a system for simulating the unpredictable and competitive nature of multi-player sports by allowing a user to practice on his own in a 'real life' environment.

The cycle time for a rotomolding process is improved through the use of a molding material comprising a blend of at least two polyethylenes having narrow molecular weight distributions and homogeneous comonomer distributions. Alternatively, the molding temperature may be reduced to conserve energy and reduce energy costs. The polyethylene blend also has a narrow molecular weight distribution of less than 3 and a density of from 0.930 to 0.950 g/cc. Rotomolded parts prepared from the blend composition have excellent impact resistance and are also resistant to warpage. A preferred process employs a blend composition which contains a blend component having a higher molecular weight and a lower density than another blend component&#x2014;this blend may be used to prepare rotomolded parts with warpage resistance and improved environmental stress crack resistance (ESCR). A highly preferred process uses a blend composition which further contains a minor amount (from 0.5 to 10 weight %) of a third ethylene blend component which has a higher molecular weight and density&#x2014;this highly preferred composition may be used to prepare rotomolded parts having warpage resistance, very good ESCR and comparatively high modulus (or stiffness).

Novel polyethylene copolymer compositions prepared with a homogeneous catalyst system are characterized by having a unique high molecular weight, low comonomer (high density) fraction. These heterogeneous/homogeneous compositions may be prepared using a solution polymerization process in which the polymerization reactor contains a gradient in temperature, catalyst concentration or monomer concentration. The heterogeneous/homogeneous compositions of this invention are easily processed into films having excellent tear strengths and low hexane extractables.

A tool is used to custom fit rubber slip-ons onto golf shoes for use in wet conditions to keep the feet of the golfer dry. The tool can be manually manipulated to cut openings into the sole of a slip-on of an appropriate size so that the openings are aligned with the spikes of the golf shoe. When openings have been cut for all of the spikes, the sole of the slip-on rests against a base of the spikes and the sole of the golf shoe. The tool has an elongated hollow body with two ends. One end has a circular cutting edge thereon and the other end has a handle thereon. After the slip-on is placed onto the golf shoe with the spikes separating the sole of the slip-on from the sole of the golf shoe, the tool is aligned with each spike in turn to cut an appropriate opening for that spike. Previously, slip-ons have been designed with pre-cut openings but these slip-ons can only be used with a specific model of golf shoe of a specific manufacturer having a specific size.

A holder for storing compact discs where each disc is contained within a conventional disc container uses a housing and anchoring means for the housing. The anchoring means is used to mount the housing in a motor vehicle. The housing contains partial partitions that are sufficiently large to hold said containers in a spaced apart parallel relationship from one another extending from front to rear of said housing when the disc containers are inserted into the housing through the front. The housing has retention means for each container to hold the containers within the housing when the containers are oriented with the groove towards the rear wall and towards the retention means. The retention means contacts a groove of each disc container and holds said container in said housing until the container is pulled out of said housing so that the retention means automatically releases itself from said disc container. When the holder is used in a motor vehicle, when desired, the housing can easily be removed from the anchoring means and removed from the vehicle. Alternatively, the housing could be removed from the anchoring means but stored in the trunk or glove box of the vehicle.
