Abstract: The present invention provides a process for extruding and pelletising a propylene copolymer. The copolymer has a content of comonomer from 5 to 40% by mole, a melt flow rate MFR2 measured at 230° C. under a load of 2.16 kg of from 0.5 to 15 g/10 min and a content of cold xylene soluble material of from 20 to 60% by weight. The process comprises extruding the propylene copolymer through a die plate into an underwater pelletiser and cutting strands of the propylene copolymer into pellets in the underwater pelletiser, wherein the ratio of the mass flow rate of the propylene copolymer to the mass flow rate of the cooling water is from 0.020 to 0.060; and the propylene copolymer comprises a polymeric nucleating agent.

Abstract: A low cost, high performance, water-swellable, flexible reinforcement member that can be used for both optical and copper communications cable. The water-swellable reinforcement members made according to the preferred process are more rigid than known reinforcement members, but are less rigid than glass pultruded rods. Communications cables utilizing these members are lightweight, water-swellable and exhibit an improved combination of strength and flexibility compared to traditional communications cables. Further, these communication cables may then be installed into underground ducts using more economical and faster installation techniques.

Abstract: The present invention relates to a polymer article that includes electrically conductive fibers to provide electrical electromagnetic interference (EMI) shielding and their method of manufacture. The invention includes a method for forming shielding materials by impregnating conductive fibers in a polymer material via direct injection of the conductive fibers into the extrusion process. The invention also includes EMI shielding polymers and products that are radio-frequency and electromagnetically shielded by parts formed of the shielding polymer.

Abstract: A coating composition for forming a water-resistant coating on fiber-reinforced articles such as rods or cables. The composition comprises an aqueous solution of a superabsorbent water-soluble polymer, a viscosity modifying agent, and optionally a lubricant. The coating formed by applying the composition effectively prevents the treated surface from water-permeation damage by absorbing water that contacts the layer containing the superabsorbent component.

Abstract: A modified manual synchronized automobile transmission for use in racing cars eliminates second gear and imparts initial rotary motion from the engine to the output shaft via a by-pass of gearing including a normally disengaged clutch. Brief engagement of the clutch causes power to feed through this by-pass gear train for just so long as the clutch is engaged and, depending on the setting of interlocked collar selector forks, will cause reverse motion of forward motion in low gear. When the car is in racing modality and moving forward in low gear, it is then possible, without further reference to the clutch, to place the main gear train in direct drive, linking the main drive shaft of the motor and the output shaft of the transmission to achieve "lock up". The invention obviates the need for a flywheel. The invention may be practiced by physical modification of an existing manual synchronized transmission.
