Abstract: A pipe coupling for joining together the ends of two adjacent pipes includes a housing for receiving the ends of the two adjacent pipes, and a locking arrangement which includes an annular chamber, and a plurality of grippers radially moveable towards the central axis of the housing from an inoperative condition to an operative condition. Each gripper includes a gripping formation for operatively gripping a pipe inserted into a bore of the housing, and a locking formation for operatively engaging a corresponding locking formation on the housing so as to axially lock the gripper to the housing. Each locking arrangement also includes a locking ring for locking the grippers to the housing so that axial displacement of the locking ring under fluid pressure within the annular chamber causes radial displacement of the grippers into the operative condition.

Abstract: The invention relates to carbonated alkaline earth metal carboxylates that are neutral, meaning they have a base value of less than 10 mg KOH/g, and that are derived from a mixture of, preferably branched, optionally cyclic, C4-C40 alk(en)yl carboxylic acids and C6-C30 alkaryl or aralkyl carboxylic acids. Also a process to make such products is claimed, as well as the use of the products to stabilize PVC.

Abstract: A computer implemented method and system for software auditability and bidirectional traceability in a software development lifecycle is provided. The lifecycle having at least development and deployment phases is bridged with a configurable workflow engine, a configuration management engine, and a managed deployment engine, interconnected with one or more representations of work to be performed or of work performed. Additionally, auditability and bidirectional traceability is provided by linking a development asset in the development phase to a deployment asset in the deployment phase so that: the development asset can be determined from the deployment asset; a deploying entity deploying the deployment asset can be determined from the development asset; a development request for developing the development asset can be determined from the deployment asset deployed; and a deployment environment where the deployment asset is being deployed can be determined from the development asset.

Abstract: A pipe coupling (10) for joining together the ends of two adjacent pipes includes a housing (12) which defines a generally central bore (13) along a central axis of the housing for receiving the ends of the two adjacent pipes, and a locking arrangement (14) at each end of the housing (12) for locking the pipes to the coupling. Each locking arrangement (14) includes an annular chamber (23) within the housing, an inlet for allowing fluid into the chamber, an outlet for allowing fluid out of the chamber, and an annular seal (24) which is arranged to move within the annular chamber axially of the housing. A locking ring (26) is provided between the annular seal (24) and a plurality of radially movable grippers (30) for locking the grippers to a pipe end within the housing.

Abstract: An apparatus for generating an effective concentration of ozone for killing bacteria, viruses and other harmful microorganisms includes a housing having an ozone chamber defining an enclosed space for containing elevated concentrations of ozone. The ozone chamber includes ports providing access to the interior of the ozone chamber. A second chamber of the apparatus houses an ozone reactor. A programmable control circuit operates both the ozone reactor and a pump for directing ambient air to the ozone reactor. The control circuit includes a motion detector mounted in the ozone chamber for activating the ozone generator of the invention and initiating the generation of ozone directed into the ozone chamber of the apparatus of the invention.

Abstract: In a process for generating an effective concentration of ozone for deodorization and destruction of contaminants. The contaminants are covered by an enclosure which is about the perimeter thereof. A conduit connected to an ozone generator is inserted into the enclosure and the distal end of the conduit is positioned at about the center of the area of contamination. Ozone is directed into the contaminant enclosure for a sufficient period of time to destroy the contaminant and deodorize the enclosed area.
