| 20110101572 | METHOD OF MANUFACTURING CHARGING ROLLER FOR ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS, AND CHARGING ROLLER MANUFACTURED BY THE SAME METHOD - Disclosed is a method of manufacturing a charging roller useable in an electrophotographic image forming apparatus and a charging roller manufactured according to the method. The method includes introducing a conductive agent and a mixture of a rubber-based material and polyolefin-based resin into an extruder, extruding the conductive agent and the mixture to obtain an extrudate, crosslinking the extrudate by electron beam irradiation, and polishing the crosslinked extrudate. The method results in an environmentally friendly and simplified manufacturing processes, and/or in the reduction of the manufacturing costs. | 05-05-2011 |
| 20120091633 | Method To Minimize Chain Scission And Monomer Generation In Processing of Poly(L-Lactide) Stent - Methods of fabricating an implantable medical devices such as stents made from biodegradable polymers are disclosed that reduce or minimize chain scission and monomer generation during processing steps. The method includes processing a poly(L-lactide) resin having an number average molecular weight between 150 to 200 kD in an extruder in a molten state.

| 20150054202 | METHOD TO MINIMIZE MOLECULAR WEIGHT DROP OF POLY(L-LACTIDE) STENT DURING PROCESSING - A method to reduce or minimize the reduction in molecular weight of a stent during processing is disclosed. The stent has a scaffolding including a polymer formulation comprising PLLA and polymandelide. The polymandelide reduces the molecular weight drop during processing, particularly during sterilization. The stent scaffolding can further include one or more additional stabilizing agents that additionally reduce the molecular weight drop during processing. | 02-26-2015 |
| 20150076743 | SYSTEM AND METHOD FOR CONTINUOUSLY MANUFACTURING CURED MEMBRANES - A method of continuously manufacturing a cured membrane includes continuously compounding and mixing a vulcanizable rubber composition in a mixing extruder while continuously removing gasses from the vulcanizable rubber composition during mixing with a vacuum. The vulcanizable rubber composition may be continuously extruded to form an extrudate, which may be continuously calendered to form a green membrane. The green membrane may be continuously cured, such as by a hot air conveyor curing system, to form a cured membrane. | 03-19-2015 |
| 20150108693 | PROCESSING BIOMASS - Methods are provided for reducing one or more dimensions of individual pieces of biomass; treating biomass, such as size-reduced biomass; changing a molecular structure of a biomass material; and, optionally, subjecting the biomass to a primary process to form a product. The methods include processing biomass materials using a screw extrusion process, and treating the biomass material with a screw extrusion process in size-reduction and treating steps. | 04-23-2015 |
