Abstract
Abstract Means for supporting, levelling and/or retaining a pipe or pipework, especially of a gas diffuser system, comprises a block or body adapted to constitute a stand for the pipe or pipe-work and having a hole or recess in or through it for the pipe or pipework. The hole or recess is eccentric with respect to the peripheral configuration of the block or body so that, by adjusting or setting the block or body angularly about the axis of the pipe or pipe-work, the effective height of the stand can be varied. In a preferred embodiment of the invention a block, which constitutes the stand for the pipe or pipe-work, is of polygonal form and has five to nine sides. A particularly convenient material for the block or body is concrete.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A gas diffuser system comprising a pipe having a plurality of gas outlets located at spaced intervals along its length, a corresponding plurality of hollow porous gas diffusers, means for feeding gas to said pipe, means mounting one such diffuser, in gas tight manner, over each of said gas outlets for the flow of gas from said pipe into the hollow interior of said diffuser, and a plurality of stands for supporting said pipe at spaced positions therealong, each such stand comprising a block having a hole through it through which said pipe passes as a close fit, said block being of polygonal form and the sides of the polygon being at different distances from the axis of said hole whereby by adjusting the block angularly about the axis of the pipe the effective height of the stand can be varied.
Claim 2
Dependent Claim
