Title: Improved folding knife
Inventor: KNIGHT NATHAN E
IPC: B26B1/02
Filed: 2006-05-19
Abstract: A folding hand tool with an open-assist mechanism that is not mechanically linked to a folding knife blade is disclosed. The open-assist mechanism is allowed to rotate around the same pivot used by the blade, and includes a lug that interacts with the kick of the blade when rotated. Because the open-assist mechanism is not mechanically linked to the blade, it has a range of free motion that promotes safety, and allows the mechanism to rotate into the blade cavity when the blade is extended. The folding knife also may have a carabiner that shares the blade cavity with the blade, with the blade nesting into the carabiner to save space, thereby giving the folding knife a smaller profile.

Title: Improvements in and relating to sifting screens
Inventor: ROBERTSON GRAHAM ALEXANDER
IPC: B01D33/03
Filed: 2005-12-14
Abstract: A frame over which woven wire mesh is to be stretched and secured to form a sieving screen and which can be used to screen solids from drilling mud recovered from downhole when drilling for oil or gas. The frame comprises a rectilinear moulded plastic frame having edge regions by which it is secured in place in a shaker. Within the frame is a plurality of rectilinear windows formed by an orthogonal array of interesting ribs also of moulded plastics material. Some of the ribs are internally reinforced by a structure comprising two spaced apart layers of orthogonal intersecting spaced apart wires, running parallel to the length and breadth of the rectilinear shape of the frame within the ribs to increase their rigidity. The edge regions of the frame are reinforced internally by metal box-section members joined at their four corners and defining perimeter reinforcement, and the ends of the wires are secured to the box-section members. The latter are encapsulated in the same plastics material from which the orthogonal array of intersecting ribs are moulded. Alternate ribs are not reinforced with wires, and the non-reinforced ribs only extend partway between the upper and lower faces of the frame.  Lengths of wire bent to form spacers and adapted to fit between upper and lower wires of the rib reinforcing structure, are joined to the upper and lower wires so as to extend therebetween and maintain the desired separation of the two layers of wires during the plastics encapsulation/moulding process.

Inventor: PORTEOUS JAMES
IPC: C02F11/12
Filed: 2006-11-07
Abstract: In a wastewater treatment system and process utilizing membrane bioreactors (MBRs), multiple, parallel series of tanks or stages each include, an MBR stage. Under conditions of normal flow volume into the system, influent passes through several parallel series of stages or process lines, which might be, for example, an anoxic stage, an aeration stage and an MBR stage. From the MBR stages a portion of M.L.S.S. is cycled through one or more thickening MBRs of similar process lines, for further thickening and further processing and digesting of the sludge, while a majority portion of the M.L.S.S. is recycled back into the main process lines. During peak flow conditions, such as storm conditions in a combined storm water/wastewater system, all of the series of stages with their thickening MBRs are operated in parallel to accept the peak flow, which is more than twice normal flow. M.L.S.S. is recycled from all MBR stages to the upstream end of each of all the parallel process lines, mixing with influent wastewater, and the last one or several process lines no longer act to digest the sludge. Another advantage is that with the thickened sludge in the last process line of basins, which ordinally act to digest the sludge, there is always sufficient biomass in the system to handle peak flow,the biomass being available if needed for a sudden heavy flow or an event that might bring a toxic condition into the main basins.
