Title: A process of treating waste water
Inventor: CASEY JOHN ANTHONY
IPC: C02F1/52
Filed: 1993-01-09
Abstract: Waste water containing organic waste material is treated by a process comprising introducing the waste water into a treatment tank, subjecting the water in the tank to aeration, allowing the organic waste material to undergo aerobic digestion and/or oxidation and then clarifying the resulting slurry containing solid particles of matter. The slurry is clarified by subjecting it to treatment in a preflocculation zone with one or more flocculating agents to coagulate the solid particles as flocs and imparting to the flocs as they are forming in the slurry a rolling action which results in the production of a heavily coagulated slurry containing substantially uniform, large, dense flocs of coagulated matter. The coagulated slurry is then introduced into a clarifier tank under conditions of laminar flow while avoiding disruption or breakage of the flocs. The dense flocs then settle to the bottom of the tank leaving a clarified liquor.

Title: Fabrication of a composite plastics structure,particularly an internal combustion engine inlet manifold
Inventor: PARR THOMAS GRAHAM
IPC: B29C65/06
Filed: 1992-01-20
Abstract: A composite plastics structure in the form of two parts of an inlet manifold housing (11) is formed by joining a first component (16) to a second component (17) at a pair of abutting non-planar joint faces (27, 28) indicated by a joint line (18). Lands (37, 38, 39 and 40) on the joint faces define gaps which are substantially eliminated when tongue (29) on the first component is welded to an abutment surface (33) on the second component by vibrating one component relative to the other. Where the joint face is inclined to a clamping force the projecting distance of the tongue is reduced. The first component is more flexible than the second component to permit the joint faces to conform under the clamping load.

Patent GB-2273088-A (GB)
Title: Aircraft cabin divider
Inventor: SIMPSON LESLIE JAMES
IPC: B64D11/00
Filed: 1994-01-06
Abstract: An aircraft cabin divider (9) formed of pivotally interconnected panel sections (10, 11, 12, 13) for erecting between two rows of passenger seats. The panel sections comprise an upper panel section (10) for mounting to the ceiling of an aircraft cabin and a lower panel section (12) for fixing to the floor of the cabin. The upper and lower panel sections are pivotally mounted to an intermediate panel section which in the installed position faces passengers sitting in the aft row of seats to one side of the divider. At least one of the pivotal interconnections is stress critical thereby to rigidise the structure in the installed position and so that under crash impact conditions, the intermediate panel section is able to follow the movement if the seat backs of the forward row of passenger seats such that the heads of the passengers in the aft row do not collide with the intermediate panel section of the divider so avoiding unnecessary injuries. To permit the intermediate panel section further freedom of forward movement, the stress critical interconnection, preferably between the intermediate panel section and the upper panel section, includes an expandable friction hinge (18) to enable the intermediate panel section to move away from the upper panel section to a maximum collapsed position determined by the expansion of the hinge. <IMAGE>

Patent GB-949785-A (GB)
IPC: C22C1/10
Abstract: 949,785. Alloys. E. I. DU PONT DE NEMOURS & CO. June 13, 1960, No. 20668/60. Drawings to Specification. Heading C7A. Compositions consisting of chromium together with one or more metals the oxides of which have a free energy of formation at 27 ‹C. of up to 75 milocals. per gram-atom of oxygen are hardened by the dispersion therein of one or more refractory oxides in the form of substantially discrete particles having an average dimension of 5-500 mÁ and a surface area of 12/D to 1200/D sq.m./gm. where D is the density in gm./ml. The refractory oxide phase is insoluble in the metal phase, has a melting point of at least 1000 ‹C. and a free energy of formation at 1000 ‹C. in excess of 90 milocals. per gram-atom of oxygen. The melting point of the metallic phase is not less than 700 ‹C. and the hardened composition has a 0À2% yield strength at a temperature 75% of the melting point of the metallic phase in degrees absolute # which is at least 1.5 times that of the metallic phase. Metals listed as suitable are Fe, Co, Ni, Cu, Cd, Th, Ge, In, Sn, Pb, Sb, Bi, Mo, W, Re, Ag, Au, Ru, Rh, Pd, Os, Pt, and they may be hardened with oxides of Y, Ca, La, Be, Th, Mg, U, Hf, Ce, Al, Zr, Ba, Ti, or with compounds such as MgAl 2 O 4 , aluminates, silicates and zirconates where each constituent oxide fulfils the above requirements. The ratio of metal : oxide may be as high as 1:1 by volume but such compositions may be pyrophoric in fine powder form and up to 30% oxide by volume is a more usual range. In a preferred method of preparing the compositions the constituents of the metallic phase are co-precipitated in the form of hydrous oxygen-containing compounds from suitable solutions with the refractory oxide particles which may be added in the form of a colloidal aquasol. The mixed oxides are then reduced in a stream of hydrogen or other reducing gas and the resulting powder compacted, sintered and worked. A preferred range of metallic composition is Fe+Co+Ni 50-90 Mo+W 0-20 Cr 10-25.
