| 20100001425 | Rapid rotational foam molding process - The nature of the rotational molding process is cyclic. It requires the temperature of the rotating mold and the plastic it is charged with to be elevated from room temperature to beyond its melting temperature and then cooled back to room temperature. Consequently, rotational molding cycle times are lengthy, which is often considered as the fundamental drawback of this plastic fabrication process. The motivation and objectives of this disclosure are twofold. The presently proposed invention focuses on developing an innovative extrusion-assisted rotational foam molding processing technology for the manufacture of integral-skin cellular composite moldings having adjacent, but clearly distinct, layers of non-cellular and cellular structures, consisting of identical or compatible polymeric grades. Its primary goal is to significantly reduce the processing cycle time in comparison with respective currently implemented technologies by employing melt extrusion in order to maximize the speed of controlled polymer melting. | 01-07-2010 |

| 20120060490 | Hydraulic Power Apparatus - An apparatus and method for providing hydraulic power to a turbine generator. A neutrally buoyant wheel having radially opposed first and second containment chambers is suspended in a reservoir containing a liquid. One chamber is filled with the liquid and the wheel rotated so that the chamber containing the liquid is in an uppermost position, which due to the configuration of the wheel results in the chamber that does not contain liquid being in a lowermost position. The uppermost chamber is coupled to an input port of the hydraulic turbine, the lowermost chamber coupled to an output port of the hydraulic turbine, and the liquid allowed to flow from the uppermost chamber to the lowermost chamber through the hydraulic turbine. After the liquid has drained from the uppermost chamber and filled the lowermost chamber, the wheel is rotated 180 degrees and the process repeated. | 03-15-2012 |

| 20110226609 | System and method for producing nanomaterials - This system and method for producing nanomaterials allows for the production of relatively high concentrations of nanoparticles with a minimum of expense, time and energy. Ultrasonic waves, produced at a power of approximately 50 W with a frequency of 26.23 kHz, are projected on a material sample while, simultaneously, a fluid stream jet is projected on the material sample. The ultrasonic waves, in the presence of the fluid jet, create cavities that explode at the surface of the solid material, leading to creation of cracks in the material surface. With the increase in the number of cracks in the material, the solid material erodes. The eroded material, which is on the nanometer scale, is collected on a suitable substrate, such as silicon. This method allows for the preparation of nanoparticles from any solid material, in particular very hard materials, such as diamond, silicon carbide and the like. | 09-22-2011 |
