Abstract: Effluent to be treated is introduced into the top of a first bioreactor (10) through an inlet pipe (16) and, after passing through second and third bioreactors (11 and 12), passes through a settling device (17), the treated effluent then flowing over a depth control weir (18) into an outlet pipe (19). The three bioreactors (10, 11 and 12) and the settling device (17) are housed in a tank having three sets of vertically-staggered transverse partitions (21, 22, 23) and a transverse settling tank partition (24). Each set of staggered partitions (21, 22 and 23) are arranged so that the bioreactors are interconnected in series, the effluent preferably being constrained to pass downwardly through each matrix (13, 14, 15) in turn against an upward discharge of very fine air bubbles from aeration panels (28) which extend under substantially the whole of each matrix. Aerobic bacteria feeds on nutrients in the effluent and grows on the roughened walls of the cross-flow matrix and the air bubbles promote sloughing of the bacteria. The apparatus therefore comprises three or more separate total mixed bioreactors working in sequence, each serving to reduce the biological oxygen demand of all the effluent whereby the biological oxygen demand is progressively reduced.

Patent GB-2268406-A (GB)
Title: Low area upper denture
Inventor: CURTIS GEORGE ERIC STANLEY
IPC: A61C13/24
Filed: 1992-07-08
Abstract: The palate area of an upper denture is reduced by virtue of the relative position of the rear edge R of the palate being closer to the front incisor teeth than the normal conventional rear edge N, thereby improving the quality of life of the user.

Title: Aerosol spray mechanism
Inventor: MIYAZAKI KIWAMU
IPC: B65D83/14
Filed: 1993-10-18
Abstract: A container 1 containing the liquid to be sprayed and a propellant gas is provided with a control member 2 having a spray hole 7. When the control member 2 is manipulated, the liquid is sprayed by the gas pressure. A sliding member 5 is provided in the control member 2 and applies pressure to a pool 42b to which the pressurised liquid and gas is supplied. When the pressure in the pool 42b reaches a specified pressure, the sliding member 5 works to cut off the supply, and when the gas pressure in the pool 42b drops, the supply is resumed. As a result, the liquid and gas are temporarily stored in the pool 42b until raised to the specified pressure, at which they escape to the spray hole 7, so that the spray liquid is always sprayed from the spray hole 7 at a specific pressure, and a specific spray state and atomization state may thereby be maintained. <IMAGE>
