Abstract: A compression pipe fitting is provided. The fitting comprises a body defining one or more sockets for receiving an end of a pipe, a clamping nut and a grip ring. The socket is encircled by a threaded face, and is internally adapted to receive a compressible O-ring. The nut can be screwed onto the threaded face of the socket and has an internal tapered surface while the grip ring has a complimentally tapered surface which, when the nut is tightened onto the threaded face, bears upon the grip ring compressing it against the pipe and compressing the o-ring located within the socket.

Abstract: A system and method to manage data messages exchanged between normally un-connected message clients, the data message management system including a participating message handling server and one or more participating message originating clients, which, in use, are configured to transmit one or more data messages to addressee clients, the addressee clients being one of participants in the system and non-participants in the system.

Abstract: This invention relates to a data message management system 10 and to methods of operating such a system. Data messages, such as e-mail and short message system (SMS) messages have become ubiquitous, but are difficult to manage and the currently un-administered nature of such messages has the effect of swamping instead of facilitating communication. The system 10 of this invention manages data messages 12 exchanged between normally un-connected message clients 14, 16 and includes a plurality of message originating clients 14 and at least one message handling server 26 that have been programmed for participation in the system. The addressee clients 16 need not necessarily be participants in the system. Each message originating client 14 is programmed with an outgoing message management program including a message routing program and user-selectable message handling rules to be attached to the outgoing data message 12.
