    Abstract: A treatment vessel (50) contains a fluidizable bed (70) of loose particulate material comprising particles of sharp sand adhered to granules of polyethylene to provide a habitat for microorganisms effective in wastewater treatment. The material has a desired density slightly greater than 1.0 g/cc, a specific surface area in excess of 600 m /m , and a particule size range of about 3 mm to 10 mm. The bed and wastewater is fluidized and aerated by air bubbles emitted from self-sealing aerators (71) disposed at the base of the bed and arranged for placement and removal from above the water level. The loose material can rest directly on the aerator surface.

    Abstract: PCT No. PCT/GB92/00800 Sec. 371 Date Nov. 2, 1993 Sec. 102(e) Date Nov. 2, 1993 PCT Filed May 1, 1992 PCT Pub. No. WO92/19546 PCT Pub. Date Nov. 12, 1992.An apertured flexible membrane (10) extends over a domed support (11). A central gas supply tube (50,82) terminates in gas outlets (51) oriented to direct the gas to flow horizontally into the space (40) between the membrane and the support to inflate the membrane away from the support so that gas from the inflated space discharges through the apertures (60) as fine bubbles and such that when the gas supply ceases the membrane collapses back into area contact with the support to seal all the apertures. This reduces clogging. The aerator is useful in the aeration of sewage or waste water and in fish or eel farms.

    Abstract: A plate is provided with pressed out spikes 4 and holes/slots 1,2,3, which is used to butt-joint a member 2A to a transverse member 2B, eg in a ceiling structure to which plasterboard are nailed. The side A of the plate is first hammered on to the end of the member 2A, then screws or nails are inserted through holes 2 to further secure the plate to member 2A. The member 2A is then attached to member 2B by inserting nails or screws through the adjusting slots 3 and holes 1. The joint prevents twisting of the member 2A. It may be used in fencing, sheds and in other applications.
