20090052822 | Metal-Backed Plain Bearing - A bearing comprises a resin matrix filled with fluoropolymer, graphite, and other discrete particles of an additive material that is attached to a backing material. The specific selection and mix of fillers with the resin matrix provides the desired blend of bearing properties such as wear resistance, fatigue and erosion resistance and low friction whilst maintaining sufficient flexibility for being formed into flanged cylindrical geometries without detriment to the adherence of the lining to the backing. A method for manufacturing a bearing comprises depositing to a backing material a fluid polymer bearing material comprised of a resin matrix filled with fluoropolymer, various fillers, and discrete particles of an additive to form a continuous consolidated bearing material, and curing the lining material to bond the lining material onto the backing material. | 02-26-2009 |

20150226259 | INTERLOCKING BEARING - A modular plain bearing is provided. The modular plain bearing includes a first end portion having a terminal edge with a plurality of first fingers and a second end portion having a terminal edge with a plurality of second fingers. The plurality of fingers cooperatively engage to provide a snap fit connection between the parts. For longer plain bearings, a bearing extender is provided. The bearing extender includes at least a first connector having a plurality of first connector fingers. The bearing extender may include either a second connector opposite the first connector having a plurality of second connector fingers. | 08-13-2015 |

20120128423 | Method and apparatus for a drywell retrofit - The present invention is a drywell retrofit top that can either replace the top portion of an existing drywell or be placed upon a newly placed drywell. The drywell retrofit top provides a flow path for storm water run-off from the top of the drywell directing the storm water run-off that falls into the drywell retrofit top trap chamber and then directs the water to a treatment system. After the treatment system process the water, the water is flows back to the drywell retrofit top to a drop chamber and then discharged into a drywell chamber where the water is able to percolate of filtrate back to surrounding native soils. The drywell retrofit top uses a precast concrete cylinder that has an integral bottom piece that is placed on top of a perforated precast concrete cylinder from the previous drywell. The drywell retrofit top has a vertical dividing wall separating the precast concrete cylinder into two chambers with a larger chamber collecting the storm water run-off. While the water is collected, sediment and heavier than water pollutants settle out in the trap chamber. An outlet pipe is place several inches or some way up the side wall of the drywell retrofit top cylinder. Once the water reaches the level of the outlet pipe, the water then flows out of the trap chamber to a treatment system that is typically situated near the drywell. | 05-24-2012 |
20120195686 | Drywell retrofit sump insert for storm water treatment - The present invention is a drywell retrofit sump insert designed to be placed inside an existing drywell or other similar Underground Injection Control (UIC). The drywell insert helps protect groundwater by removing pollutants from raw storm water runoff that enters the drywell before the drywell infiltrates the storm water into the ground. Once the raw storm water enters the drywell retrofit sump insert, sand, silt, grit, and other high-density pollutants settle out of the storm water stream and accumulate in the bottom of the drywell retrofit sump insert. Oil, grease, and other low-density pollutants float on top of the standing water inside the drywell retrofit sump insert and are kept inside by the oil baffles on the outlet holes. The drywell retrofit sump insert is comprised of a rigid cylinder with an integral flanged bottom attached by means of a watertight joint. | 08-02-2012 |

20160047279 | VORTEX TUBE SUPPLYING SUPERHEATED VAPOR FOR TURBINE POWER GENERATION - The vortex tube when properly used within a Rankine Cycle can produce phenomenal results. This invention functionally describes the preferred vortex tube used to produce superheated vapor from a compressed heated liquid without summoning the additional heat required for latent-heat to effect vaporization. The vortex tube provides superheated vapor to a turbine for generating electricity burning 50% less fossil fuel, also releasing 50% less carbon emissions to the environment. The vortex tube extends the efficient Rankine Cycle temperature range well below 150° F. with the proper refrigerant choice. The physical size and function of the heating equipment is reduced. This invention delivers new thermal efficiencies for both the Rankine Cycle and the Organic Rankine Cycle. | 02-18-2016 |
