Patent CA-2092130-A1 (CA)
Title: Ball valve seats for low torque operation and full pressure range sealability
Inventor: KABEL TERRY D
IPC: F16K5/06
Filed: 1993-03-22
Abstract: ABSTRACT    Seats, seat seals, and seat pockets for a floating ball valve are disclosed, which permit full pressure range sealability and low operating torque over the entire range of working pressures.  A cantilevered spring action biases seat seal lips into sealing engagement with the ball.  Seat pockets in the body house the seat members and restrain them against bending or twisting.  The seal lips extend radially inwardly and axially outwardly from the seat members, and are deformed into the seat pockets by the ball upon assembly, biasing them into sealing engagement with the ball on both sides of the valve with a self-centering effect.  The main bodies of the seats each include a curved surface spaced apart from the seal lips, which make sealing contact with the sealing surface of the ball under predetermined conditions.  An annular groove on the axially outer side of each of the seats, adjacent to the outer sides of the cantilevered seal lips, houses a resilient seal member which seals  against the  seat pocket  and the  lips under  low operating pressures.  The seal groove has an expanded portion at its radially outer end into which the resilient seal member may be moved by differential pressure under intermediate to high operating pressures, which causes the loss of the seal against the seat pocket.  The seat pockets have lips which shield the seats from direct contact with the flow path through the valve,  thereby protecting the seats from abrasive or otherwise harmful substances.

Patent CA-2095946-A1 (CA)
Inventor: EDLINGER ALFRED
IPC: C22B7/00
Filed: 1993-05-11
Abstract: Abstract In the processing of mainly inorganic refuse incinera-tion products polluted by heavy metals and/or heavy metal compounds, and/or analogues of such products, to give envi-ronmentally acceptable products by melt-thermal treatment, an iron-containing melt is used whose iron content can be adjus-ted by addition of iron or an iron compound. The melt is first melted above 1300°C in a reactor. The melt is then oxi-dised with vigorous agitation by blowing in oxygen-containing gas until all the metals and metal compounds present in the reactor have been converted to the oxide form, the melt being kept above 1450°C and preferably at about 1500°C, at least at the end of the oxidation. Subsequently, the melt is reduced, preferably by means of a part fraction of the refuse incin-eration product and/or iron, preferably in the form of scrap, and/or hydrogen. The reduction can then be continued by means of added aluminium and/or calcium and/or ferrosilicon. If ap-propriate, metal melt is fractionated in a lower part of the reactor and slag melt is separately collected as a super-natant layer. Heating energy can be saved by heat exchange and recirculation of fluid.

Patent CA-2130760-A1 (CA)
Inventor: STENHOUSE WILLIAM L
IPC: D03D49/62
Filed: 1994-08-24
Abstract: A reed 28 for a loom is disclosed which includes a frame with upper and lower baulk mechanisms D, E that carry a front row B of dents 30 on the beat-up side of the frame and a back row C of dents 34 staggered in alignment with dents 30.  Lower baulk mechanism E includes a stepped clamping portion which is reduced in depth compared to the depth of the upper portion of the lower baulk mechanism E such that dents 34 are shorter in height in the lower baulk mechanism E than dents 30.  This renders one of the rows C of dents 34 able to be disposed farther from the other row B of dents 30 than if they were to extend into the clamping portion of the lower baulk mechanism E the same amount as dents 30.  In this way, the angle of attack between the dents and the warp yarn ends is reduced and offers less resistance to the yarn passage, reducing abrasion of the warp yarns, reducing the lint buildup between the dents, and increasing efficiency by reducing the incidence of friction between adjacent warp yarns.

Title: Method and apparatus for in situ water purification including sludge reduction within water bodies by biofiltration and for hypolimnetic aeration of lakes
Inventor: EHRLICH KARL F
IPC: C02F7/00
Filed: 1995-03-20
Abstract: Disclosed are a method of the in situ purifi-cation by aeration and biofiltration, of water from lakes, bays, and aquacultural and within waste water treatment systems. In a first step, polluted, nutrient rich and/or oxygen deficient water is drawn, from with the water body, usually near the bottom, into a submerged chamber located near the surface of the water body, to cause the water to be oxygenated, in part, from three potential sources of oxygen, air used in the airlift to bring the water to the submerged chamber, then air diffused from the surface as the moving water is brought in contact with the atmosphere and finally from supplemental aeration diffused within the deeper portion of the submerged chamber so that the rising bubbles operate in a counter current manner to the water flow providing efficient gas exchange. In a second step, the water that has been oxygenated is passed through a biofilter comprising a filter bed made of filtering media, which is located within the water body. The filtering media may be preinoculated with beneficial micro-organisms and essential nutrients. Also disclosed is an apparatus for use to carry out this purification method. The same apparatus can also be used to provide hypolimnetic aeration within a lake without destratifying the water column outside the apparatus. It can further be used to draw organic sludge or sediments from the body of the water body and bring these solids in contact with a continuous or intermittent supply of microbial cultures specifically grown to optimize production of enzymes, which solubilize said organic sludge of sediment. Biochemical oxygen demand (BOD) generated by the sludge solubilization can then be treated by aeration and biological filtration. The apparatus for sludge solubilization is designed to avoid the suspension of solids in the water column beyond the limits of the apparatus.
