Abstract: An improved cladding board mounting system for mounting cladding boards (100) adjacent a surface to be concealed. Each cladding board (100) includes at least one support member (130) on the interior face (120) of the cladding board. The system further includes at least one mounting member (170) which includes an engaging formation (172) adapted for releasable engagement with a complementary engaging formation (132) of a respective support member. The mounting member also includes a second segment (174) for releasable connection to the surface to be concealed. Preferably a mounting bracket (70) extends between the surface to be clad and the mounting member (170).

Abstract: A cladding board (10) for fixing in partial overlapping relationship with a like board (10). The board (10) includes a longitudinally extending first face (11) which, in use, partially overlaps with the opposing face of a like board (10) and a retaining formation (12) in the first face (11) adapted to captively retain an aligning spline (13) having a complementary retaining formation.

Abstract: This invention relates to a formulation for preparing a dry formulation for preparing an autoclave cured cementitious product comprising:a cementitious material;a siliceous material; anda dehydroxylated clay mineral.

Abstract: The present invention relates to a dual flush cistern. The cistern incorporates a flushing valve 12 located in the base of the cistern, the flushing valve 12 having a stem 11 able to be lifted to open the flushing valve 12. Float 30 is fixed to stem 11 and is mounted within float housing 13. Float housing 13 is mounted relative to the cistern such that it is below the normal water level when the cistern is full and above the normal water level following a partial flush. The closure of flushing valve 12 is dependant on float 30 which falls with the water level within float housing 13. The drainage rate of water from float housing 13 is controllable in response to the type of flush desired.
