20100196649 | Method of refurbishing recycle disc - A novel method for refurbishing a rubber disc used in a recycle machine comprises the steps of cleaning and sanding the surface of the disc; priming at least the surface of the disc with a liquid primer or interfacing agent (adhesive); placing the disc in a portion of a mold; charging or filling the mold with a polymer (synthetic rubber or elastomer) mixed with a suitable catalyst, hardener or activator; allowing the synthetic rubber polymer to exothermally cure inside the mold; and withdrawing the disc from the mold. The resulting refurbished disc is characterized by a new outer surface layer (synthetic rubber) adhered to the original rubber disc. In an alternatively preferred method, one or more relatively small holes are formed in the surface of the disc prior to molding the new outer surface layer on the disc whereupon the strength of the bond between the new outer layer and the original disc is enhanced. | 08-05-2010 |

20140318631 | METHODS AND SYSTEMS FOR CONVERTING FOOD WASTE OIL INTO BIODIESEL FUEL - This invention provides the market with low-cost retrieval of valuable used cooking oil to customer distribution centers, where a mobile production unit visits to create biodiesel fuel, which can be immediately used by customers to fuel their fleet. In some variations, a method comprises identifying a network of customer distribution centers, collecting used cooking oil transported from users to customer distribution centers, providing a mobile reactor to convert used cooking oil into biodiesel fuel under effective reaction conditions, producing biodiesel fuel on-site at the customer distribution centers, and introducing the biodiesel fuel, directly or via a fuel blend, into fleet vehicles. Related systems and apparatus are also disclosed. This invention provides a clean source of energy from waste, a lower-cost alternatives to petroleum-derived diesel fuel, and improved environmental footprints including lower fuel use and lower total carbon emissions. | 10-30-2014 |
20150031097 | MOBILE PROCESSING SYSTEMS AND METHODS FOR PRODUCING BIODIESEL FUEL FROM WASTE OILS - The present invention improves biodiesel production in several ways. Unique combinations of unit operations and flow configurations are disclosed in mobile processing units that are feedstock-flexible and can be dynamically deployed in a distributed way. In some embodiments, a process includes introducing a waste oil and an alcohol into a reactor with an esterification-transesterification enzymatic catalyst. Free fatty acids are reacted with alcohol to produce fatty acid alkyl esters, and glycerides are reacted with alcohol to produce fatty acid alkyl esters and glycerin. A membrane separator removes glycerin, water, and alcohol. Unreacted free fatty acids are then separated and recycled, to generate a product stream with fatty acid alkyl esters. A genset may be provided for combusting glycerin to produce electrical power and thermal heat as co-products. This biodiesel process may be energy self-sufficient, require no external utilities, and avoid direct discharge of wastewater. | 01-29-2015 |

20140052957 | TRANSLATION TABLE AND METHOD FOR COMPRESSED DATA - A translation table has entries that each include a share bit and a delta bit, with pointers that point to a memory block that includes reuse bits. When two translation table entries reference identical fragments in a memory block, one of the translation table entries is changed to refer to the same memory block referenced in the other translation table entry, which frees up a memory block. The share bit is set to indicate a translation table entry is sharing its memory block with another translation table entry. In addition, a translation table entry may include a private delta in the form of a pointer that references a memory fragment in the memory block that is not shared with other translation table entries. When a translation table has a private delta, its delta bit is set. | 02-20-2014 |
