摘要： A sealing device for sealing the opposite sides of upper and lower converging liquid pervious moving belts used in dewatering a liquid slurry containing fibrous materials wherein the upper and lower liquid pervious belts converge from an entrance portion to an exit portion and wherein the sealing device is formed from an elastomeric material and has a base portion and two integral diverging lip portions which taper vertically and horizontally from the entrance portion to the exit portion. The inner surfaces of each lip portion has a first tapered surface extending from at least adjacent to the entrance portion to at least adjacent to the exit portion of the apparatus and a second tapered surface extending from at least adjacent to the exit portion to at least adjacent to the entrance portion of the apparatus. Each sealing device is preferably formed as two sections each of which may be adjusted for vertical, horizontal and pivotal adjustment.

摘要： A system for treating a nitrate contaminated liquid to remove deleterious or undesirable nitrates therefrom wherein a supply of ionized nitrogen is entrained into a continuous stream of a nitrate contaminated liquid and thereafter is exposed to treating apparatus which changes the nitrates in the nitrate contaminated liquid into at least ionized nitrogen which then combines with the ionized nitrogen entrained in the continuous stream of a nitrate contaminated liquid to form a separated nitrogen gas and a treated liquid.

摘要： A system for treating a contaminated liquid wherein atmospheric air is fed into an oxygen generator with the resulting gases fed into an ozone generator and the resulting gases fed into a treatment tower as the contaminated liquid flows through the treatment tower is modified by locating apparatus between the oxygen generator and the ozone generator which apparatus receives the gases from the oxygen generator, ionizes such gases and feeds the ionized gases to the ozone generator.
摘要翻译：一种用于处理污染液体的系统，其中大气空气被供给到氧气发生器中，所产生的气体被供给到臭氧发生器中，并且当污染液体流过处理塔时，被送入处理塔的所得气体通过定位装置氧气发生器和臭氧发生器，该装置接收来自氧气发生器的气体，将这些气体电离并将电离气体供给臭氧发生器。
