Abstract: A system is used for treating contaminated water, that may include some amount of polyacrylamides, emulsified hydrocarbons, and sequestered divalent cations. The system includes at least one pre-treatment tank for initial processing of the contaminated water. Thereafter, the water may be fed to at least one chemical treatment tank fluidically connected to the pre-treatment tank. This treatment tank includes a chemical injection system connected to an interior thereof for introducing a variety break operations, coagulant addition operations, and/or flocculent addition operations. At least one clarifier is fluidically connected to the at least one chemical treatment tank, and includes a mechanical contaminant removal system. A filter skid is fluidically connected to the at least one clarifier, and includes a plurality of filter cartridges.

Abstract: The disclosure describes a novel approach for treating water, such as oilfield production waste. The disclosure describes novel methods for chemically treating contaminated water, such as chemical processes for softening water, demulsifying hydrocarbons, destroying a sequestering effect on divalent cations, destroying any detectable amount or over 99% of aerobic and anaerobic bacteria, and breaking long chain polymers. The disclosure further describes novel methods for clarifying contaminated water to remove suspended solids.

Abstract: A plastic polishing composition and method for making such a composition in emulsion form containing a fatty acid, an alkanolamine, cetyl alcohol, glyceryl monostearate, and liquid forms a carrier for an abrasive material, an acrylic filler, an anti-static agent, and a hydrocarbon solvent. The composition cleans as it polishes translucent and opaque plastic surfaces by removing foreign matter and filling minute surface scratches in a one-step operation.

Abstract: Automatic label applying apparatus comprises a conveyor for moving packages to a weigh scale and from thence to a label application station where a reciprocably movable vacuum type heated label applicator receives an appropriately printed label from a label issuing means and applies it to the appropriate package. A vacuum system connected to the label applicator holds the label thereon and also operates a pneumatic cylinder for a lock-out arm to prevent the heated label applicator from making contact with and burning a package when the vacuum system senses that no label is present. An electronic control system, including a photocell for sensing if a package is at the station and also including a limit switch actuated by the lock-out arm (and therefore indicative of the presence or absence of a label), operates to stop the conveyor after a predetermined interval of time in the event that a package is present at the station but no label is available to the label applicator.
