Inventor: JAGER VERNON DE
IPC: F04D7/04
Filed: 2001-06-13
Abstract: An apparatus and method for slurrying waste materials and drill cuttings. The apparatus includes a pump having a chamber an inlet opening into the bottom of the chamber, an impeller, an outlet on one side of the chamber for removal of material into a discharge line, and circumferentially spaced circulation ports in the chamber side. The impeller extends below the chamber and breaks up debris in addition to drawing material into the pump chamber. The pump may be rotated by a swivel connection and moved and manipulated in the tank by a crane arm, or it may be suspended by cable or other means. The pump stirs up a slurry by rotating the impeller, opening the circulation ports at least partially so that the material entering the bottom inlet to the chamber and being agitated by the impeller is forced out of the circulation ports. The pump can operate in the stirring mode until the material to be removed is generally homogenious, whereupon the circulation ports can be closed allowing the impeller to direct the slurry through the side outlet of the chamber into the discharge line. The stirring or slurrying mode can be combined with a discharge mode by opening the circulation ports as required to slurrify the material while it is pumped out the discharge line. An auxiliary discharge conduit may also be connected with the outlet to discharge material back into the tank to exchange upper fluid layers with lower layers.

Abstract: The present invention relates to virulent (lytic) Listeria monocytogenes phage from the Myoviridae family, preferably P100, alone or in combination with other virulent phages. P100 and the endolysin from P100 can be administered to food products, to the components that will be added to food products, and/or to the infrastructure of the food processing plants within which such food products are processed, or the containers or wraps in which such foods are stored and/or shipped, in order to reduce Listeria monocytogenes contamination. P100 can also be used in the present invention to identify Listeria monocytogenes bacteria present on (or within) foodstuffs, as well as those Listeria monocytogenes bacteria present in the equipment or the general environment of the food processing plants in which the foodstuffs are being processed and in animals infected with Listeria monocytogenes. The phage and the endolysin of the present invention can also be used to treat animals infected with Listeria monocytogenes. P100 will kill the bacteria that are within its host range with great efficiency and will propagate to high titer thereon. P100 can be combined with other lytic phage, and/or with other antimicrobial agents to reduce or eliminate Listeria.

Abstract: The use of falling-film evaporation and a concentration means such as centrifugal separation to dehydrate and concentrate a water-in-oil polymer emulsion or suspension is disclosed. In a preferred embodiment, a water-in-oil polymer composition containing less than about 25% active polymer solids is dehydrated in falling-film evaporator to produce an evaporator concentrate containing less than about 5.0% water. The evaporator concentrate then flows to a separation device such as a centrifuge, wherein oil is removed to produce a composition that is substantially a polymer and emulsifying surfactant-in-oil composition containing in excess of about 60 weight % polymer solids. The centrifuge raffinate may optionally be treated in a second separation means to capture additional polymer solids, with optional recycle of the oil-rich raffinate. The concentrated polymer composition is preferably stabilized with a steric stabilizer to produce a free flowing liquid product.
