  • Publication number: 20070275646
    Abstract: A head meat processing system and a head meat processing method. The processing system includes a rod for receiving and positioning the head, a fastener for grasping a portion of the head and a member for advancing the head onto a horn assembly while the portion is clamped and a horn assembly. The head meat processing method includes positioning a hog head above a fastener, grasping a portion of the head with the fastener, removing the portion from the head, advancing the head having the portion removed along a horn assembly and separating a lower jaw from the head.

  • Patent number: 7301066
    Abstract: Methods of treating ground water and methods for reducing contaminants (e.g., chlorinated compounds in contaminated ground water) to harmless compounds in the presence of an elemental metal treatment composition. Said methods comprise injecting a treatment solution comprising a colloidal suspension of elemental metal particles (e.g., iron, a tin, a zinc, a palladium and mixtures thereof) having a nanoscale particle size and a carbohydrate in an organic liquid (e.g., dodecane, butyl acetate and polypropylene glycol ethyl ether acetate and mixtures thereof) into the ground, proximate to the contaminated ground water.

  • Publication number: 20050217427
    Abstract: The invention provides methods of producing colloids of nanoscale metallic particles particularly useful in the in situ environmental remediation of chlorinated solvents. The methods include ball milling an elemental metal to form a colloid of nanoscale metallic particles having ideal size and metallurgical properties to enhance the reductive dehalogenation of halogenated hydrocarbons.

  • Publication number: 20040245187
    Abstract: When elemental iron is in the presence of chlorinated compounds (contaminants) a naturally occurring reaction takes place and the chlorinated compounds are reduced and form harmless compounds. The production of extremely small metal particles containing elemental iron or a mixture of elemental iron and a second metal is imperative to this method of treating contaminants and is the subject of the present invention. When the particle is small enough a surfactant is not required for the particle to do its job. The elemental metal may be kept in an elemental state by keeping it in an oxygen-scavenging environment. This is achieved by either suspending the nanoscale metal in a carbohydrate solution or by injecting a carbohydrate solution in atomized form into the gas used to inject the metal into the subsurface soil. Additionally, the present invention is to a method of using elemental metal to reductively dehalogenate halogenated hydrocarbons, to reduce soluble metals and to treat metalloids in subsurface soil.
