摘要： An electronic turbocharger control system for an internal combustion engine is provided to control at least one turbocharger by controlling a bypass valve and a wastegate in response to the engine speed, engine load, ambient temperature, and the operating environment's barometric pressure wherein the turbocharger is controlled to operate within predetermined islands of efficiency on a pressure ratio versus mass airflow map thereby allowing the adaptation of one turbocharger assembly for various applications. The method and apparatus provides improved engine efficiency and increases low speed torque.

摘要： EPM and/or EPDM compositions exhibiting superior green strength as compared to conventional EPM/EPDM compositions are attained by adding, along with the rubber curing agents and various conventional additives as desired, colemanite and/or alumina trihydrate. Colemanite, alumina trihydrate or a mixture of the two have unexpectedly been found to enhance the green strength of EPM/EPDM compositions prior to vulcanization. The green strength promoters of this invention utilized in EPM/EPDM rubber compositions allows for faster mixing (shorter mixing cycles) and improved processing rates, such as faster calender throughput rates, to be achieved.

A method for covering a roof comprises the steps of applying layers of self-adhering sheet material prepared from an uncured heat seamable polymeric composition of matter comprising blends of polyolefins, semi-crystalline polyolefins and crystallinity enhancing polymers to the roof being covered; overlapping adjacent edges of the layers; heating the overlapped areas to about the softening point of the sheet material and seaming the overlapped areas under sufficient pressure to provide an acceptable seam strength. For practice of the method, the composition of matter is self-adhering, without the use of an adhesive.

摘要： Guayule-type resins are chemically treated with a reactive phenolic resin and a polyether such as an amine terminated polyether. The treated guayule resin has improved physical properties such as higher softening points. The resulting composition is suitable as a rubber additive since it improves various physical properties such as building tack, tear strength, hysteresis loss, and the like.
