  • Patent number: 5407379
    Abstract: Improvements to blast cleaning apparatus, and particularly to a media control device which contains a fixed orifice placed between the abrasive supply pot and a media outlet to the compressed air line to meter the media flow into the air line and means to maintain a positive pressure differential between the supply pot and the air line further includes a means to equalize the pressure between the air line and a media passage immediately below the orifice. An additional improvement comprises adding a flow straightening device upstream of a bend in the air line so as to reduce back-mixing in the bend and consequently the turbulence of air downstream of the bend and across the media outlet into the air line.

  • Patent number: 5401205
    Abstract: A media control valve used to meter and dispense an amount of abrasive media from a supply pot to a compressed air line for blast cleaning comprises a vertical media passage communicating with the supply pot and an air flow tube and a restricting orifice in the media passage to meter the amount of abrasive media flowing therethrough the vertical passage into the air flow tube, the media passage downstream of the orifice converging into a slot-shaped outlet into the air flow tube wherein the length of the outlet is directed along the direction of air flow through the air flow tube so as to reduce the perimeter of the outlet placed perpendicular to air flow and consequently reduce turbulence as the air passes across the outlet. The media valve is particularly useful in metering and dispensing sodium bicarbonate media from a supply pot to the air conveying line by means of differential pressure across the orifice.

  • Patent number: 5391787
    Abstract: The present invention provides a process for preparing a C.sub.14 -C.sub.22 fatty acid alkaline earth metal salt product which is essentially free of C.sub.14 -C.sub.22 fatty acid or C.sub.14 -C.sub.22 fatty acid glyceride. The glyceride content of C.sub.14 -C.sub.22 fatty acid starting material is hydrolyzed with a water-soluble basic compound such as sodium carbonate in the first step of the process. The C.sub.14 -C.sub.22 fatty acid salt aqueous dispersion formed in the first step is converted to an alkaline earth metal salt in a subsequent process step. A biologically active constituent such as methionine hydroxy analog can be incorporated as an additional ingredient during the processing.
