摘要： A thermal expansion compensating device has a conduit with a first opening and a second opening for connection to a first pipe and a second pipe of a hot water system, respectively, the first and second pipes being formed by removing a section from a length of pipe of the hot water system. A pre-tensioning force is applied to the device to axially displace the first opening from the second opening until after connection of the openings of the pipes. A resiliently deformable pipe segment defines a portion of the conduit between the first opening and the second opening and is resiliently deformed to a tensioned position by the application of the pre-tensioning force. Once the hot water system is activated, the pipes axially thermally expand such that the first opening moves towards the second opening and the pipe segment moves from the tensioned position towards a rest position decreasing the stress on the device.

摘要： A pipe fitting having a first body and a second body that together at least partially define a fluid flow passage. The first body defines a first portion of the fluid flow passage that extends from a first end of the fluid flow passage to a first internal opening. The second body defines a second portion of the fluid flow passage that extends from a second internal opening to a second end of the fluid flow passage. The first body has a first interface surface that surrounds the first internal opening, the first interface surface having a plurality of anti-rotation grooves. The second body has a second interface surface that surrounds the second internal opening and engages with the first interface surface. The first internal opening is in fluid communication with the second internal opening. The second interface surface has a plurality of anti-rotation fingers that are each received by and engage with a corresponding one of the anti-rotation grooves. Rotation of the second body relative to the first body is resisted by the engagement of the anti-rotation fingers with the anti-rotation grooves.

摘要： A heat exchanging to exchange heat between a first fluid and a second fluid has a thermally conductive conduit with a double wall construction with an inner wall and an outer wall fixed thereto and defining a plurality of leak channels therebetween. Any fluid entering the leak channels is conveyed and detected to indicate a potential breach of the inner wall or outer wall. One of the fluids may be warm waste water and the other fluid may be clean water under pressure to recover heat from the waste water. An interleaving baffle located in the fresh water conduit increases heat transfer.

摘要： A fastener assembly for releaseably fastening a first body to a second body is disclosed. The fastener assembly has a manual rotating mechanism to permit closing of the fastener by hand. Once closed, the manual rotating mechanism is not easily accessible to the user by hand. A separate tool operating rotating mechanism is accessible by a tool when the fastening mechanism is in the closed position. The fastening mechanism can be used to fasten a lid to a box in which case the lid has a recess for receiving the manual rotating mechanism.
