Abstract: The present invention relates to methods for reducing the population of (e.g., killing) arthropods employing compositions including medium chain peroxycarboxylic acid, and to the compositions. The methods include applying a medium chain peroxycarboxylic acid composition to an arthropod or a surface or area suspected of housing an arthropod.

Abstract: A pipe clamp assembly for joining pipe ends of the same or different diameters in a linear relationship for use in acid waste disposal systems. The clamp assembly comprises a flexible clamping band which surrounds the pipe ends to be joined, an elastomeric, circumferential, thin sealing gasket beneath the clamping band and, when joining pipe ends of differing diameters, an elastomeric, circumferential transition coupling within the sealing gasket, the transition coupling having grooves on the exterior surface to engage sealing beads on the interior surface of the sealing gasket, to form a sealing relationship between the exterior surface of the transition coupling and the interior surface of the sealing gasket, and circumferential sealing beads on the interior surface of the transition coupling, to form a sealing relationship with the exterior surface of the reduced diameter joint or pipe to be sealed, thereby providing a clamp assembly adapted to clamp together pipes or joint ends of different diameters.

Abstract: A liquid drainage system leak detection apparatus including a cap for closing a port in the drainage system and defining at least a liquid fill opening for communicating therewith; a liquid fill coupling connected to the cap and communicating with the liquid fill opening; a liquid pressure gauge communicating with the drainage system via the cap and adapted to monitor liquid pressure in the drainage system; and a shut off valve disposed between the fill coupling and the fill opening.

Abstract: A pipe clamp assembly for joining joint or pipe ends of different diameter in a clamping relationship, which clamp assembly comprises a flexible clamping band which surrounds the ends of the pipe or joint to be joined, a polymeric circumferential, thin sealing gasket beneath the clamping band and a polymeric circumferential transition coupling within the sealing gasket, the transition coupling having grooves on the exterior surface to engage sealing beads on the interior surface of the sealing gasket, to form a sealing relationship between the exterior surface of the transition coupling and the interior surface of the sealing gasket, and circumferential sealing beads on the interior surface of the transition coupling, to form a sealing relationship with the exterior surface of the reduced diameter joint or pipe to be sealed, thereby providing a clamp assembly adapted to clamp together pipes or joint ends of different diameters.
