Abstract: A propylene-ethylene copolymer includes propylene as a primary monomer, an ethylene content (ET) of 3.0% to 5% by weight, a melt flow rate of from 20 to 45 g/10 min, a xylene soluble fraction (XS) of from 2.0% to 7.0% by weight, and an XS/ET ratio of less than or equal to 1.51.

Abstract: A transportation system on earth comprising a defined transportation universe having defined contents (real or virtual) and a defined transportation universe boundary (real or virtual). There is a central control system for controlling the transportation universe. A plurality of vehicles have a vehicle identification unit used by the central control system and connectable in two-way data communication with the central control system and can therefore become a transportation universe controlled vehicle. Each vehicle in the transportation universe is controlled by the central computer system interacting with the identification unit in the vehicle. Each vehicle is motor powered so as to be movable within the transportation universe under the control of the central control system.

Abstract: A transportation system comprises a defined transportation universe having defined contents, authorized vehicles and a defined boundary. There is a central control system. Vehicles each have an identification unit connectable in two-way data communication with the central control system. Each authorized vehicle is powered and self-movable within the transportation universe while controlled by the central system. Authorized vehicles can enter into or exit from the transportation universe through the transportation universe boundary at one of a plurality of entry points or a plurality of exit points respectively. The entry of each vehicle into the transportation universe is authorized by the central control system. Each authorized vehicle is controlled along the journey from entry to exit in co-operation with each other authorized vehicle when in the transportation universe to thereby provide fully collaborative control of traffic in the transportation universe.

Abstract: A funnel structure for filtering and discharging storm sewage into an aquifer from a bottom of a manhole. The funnel is adapted to receive unitized filters. These filters can be selected from known materials to most effectively remove known types of contaminants from the storm sewage. The structure is designed to be employed both as a new installation, say within a park or a residential subdivision, to reduce leads on the storm sewage system and as an adaptation to existing manholes within a storm sewage collection system, thus augmenting the capacity of that system.
