  • Patent number: 5200189
    Abstract: A peroxyacid antimicrobial concentrate and use composition is provided comprising a C.sub.1 to C.sub.4 peroxycarboxylic acid, and a C.sub.6 to C.sub.18 peroxyacid. The combination of these acids produces a synergistic effect, providing a much more potent biocide than can be obtained by using these components separately. Other components can be added to the composition such as hydrotrope coupling agents, stabilizers, etc. An effective antimicrobial use solution is formed at low concentrations when the concentrate composition is diluted with water to a pH in the range of about 2 to 8. Sanitizing of substantially fixed, "in-place" processing lines in dairies, breweries, and other food processing operations is one utility of the composition.

  • Patent number: 5194230
    Abstract: A solid product static brake (10) is provided which is employed in cast solid chemical block dispensing systems for slowing a generally downward gravitationally driven movement of the solid chemical block when placed or installed in a chemical dispenser. The brake provides the ability to prevent the destruction of the cast solid during installation due to mechanical shock. The static brake comprises a horizontal base frame (12), and a plurality of rigid blade members (18) extending from the base frame in a generally perpendicular direction. When a new solid block is installed, the blade members contact and slow the solid block as it falls into the dispenser.
