20090145569 | Method for casting composite ingot - A method and apparatus are described for the casting of a composite metal ingot having two or more separately formed layers of one or more alloys. An open ended annular mould is provided having a divider wall dividing a feed end of the mould into at least two separate feed chambers. For each pair of adjacent feed chambers, a first alloy stream is fed through one of the pair of feed chambers into the mould and a second alloy stream is fed through another of the feed chambers. A self-supporting surface is generated on the surface of the first alloy stream and the second alloy stream is contacted with the first stream. By carefully selecting conditions and positions where the alloy streams meet, a composite metal ingot is formed in which the alloy layers are mutually attached with a substantially continuous metallurgical bond. | 06-11-2009 |

20080226859 | Flotation objects for outdoor ponds - A flotation object floats on the surface of outdoor ponds and other bodies of water. The flotation object includes a circular middle portion and first and second hexagonal end portions. When the flotation objects are placed in a pond the objects contact each other in such a way that the flotation objects substantially interlock. | 09-18-2008 |
20100065559 | Collection Receptacles for Gases - A gas collection receptacle includes a segmented top portion and one or more side portions creating a volume for collecting gases. The gas collection receptacle, configured to float on a pond, lagoon, or other area, also includes interlocking side and end portions enabling multiple receptacles to connect, thus forming a substantially continuous covering. | 03-18-2010 |
20100311111 | Methods for Optimizing Production and Collection of Reusable Gases - Methods for increasing methane emitted from organic waste and for collecting methane and other gaseous bi-products. A gas collection unit collects gas in a first separation tank, wherein the gas is separated into methane and other components. The methane is collected, and other components are diverted. A second separation tank receives diverted components combined with an acidic solution and further separates the components into carbon dioxide and other compounds. The carbon dioxide is collected for reuse in a variety of applications. | 12-09-2010 |
20110319341 | METHOD OF CONTROLLING PESTS WITH BIOSURFACTANT PENETRANTS AS CARRIERS FOR ACTIVE AGENTS - A penetrating composition can include an active agent that has an activity that is either beneficial for plants or controls pests. The composition can also include a penetrant that is present in an effective amount for carrying the at least one active agent into or through a medium, the medium being at least one of a plant, soil, or pest. Also, penetrating composition can be used for increasing the permeation of an active agent in an animal. The composition includes an active agent having an activity that is beneficial for an animal. Also, the composition includes a penetrant selected from the group consisting of biosurfactants, glycolipids, lipopeptides, favolipids, lipoproteins, phospholipids, lipopolysaccharide-protein complexes, polysaccharide-protein-fatty acid complexes, and combinations thereof. A biosurfactant composition can include an effective amount of a biosurfactant for controlling a pest, preserving a plant cutting, or reducing effects of environmental stress on a plant. | 12-29-2011 |
20120058895 | COMPOSITIONS AND METHODS FOR CONTROLLING PESTS WITH GLYCOLIPIDS - Biosurfactants produced by microbes are used to control pests. The biosurfactants can be produced by cultivating a biosurfactant-producing microbe, producing a fermentation broth, and obtaining the biosurfactant from the fermentation broth. Alternately, the biosurfactants can be produced in situ in the environment of the pests by applying a carbon substrate to the pests' environment, which permits naturally-occurring biosurfactant-producing microbes to grow and to generate the biosurfactants. The biosurfactants have pesticidal qualities, and can be used to control a variety of pests, while being biodegradable and otherwise avoiding adverse environmental effects that have often been associated with conventional synthetic pesticides. | 03-08-2012 |
