Patent SE-8403445-L (SE)
Inventor: BARTON T G
IPC: B09B3/00
Filed: 1984-06-28
Abstract: A method and apparatus are disclosed for the pyrolytic destruction of toxic or hazardous waste materials using equipment that is compact and transportable. The waste materials are fed into a plasma arc burner where they are atomized and ionized, and then discharged into a reaction chamber to be cooled and recombine into product gas and particulate matter. The recombined products are quenched using a spray ring attached to the reaction vessel. An alkaline atomized spray produced by the spray ring neutralizes the recombined products and wets the particulate matter. The product gas is then extracted from the recombining products using a scrubber, and the product gas is then burned or used for fuel. Monitoring devices are used to check the recombined products and automatically shut down the apparatus if hazardous constituents are encountered therein.

Abstract: A scroll type fluid displacement apparatus is disclosed which includes a pair of scrolls each having a circular end plate and a spiral element extending from one end surface of the circular end plate. The pair of scrolls are maintained at an angular and radial offset so that both spiral elements interfit to form a plurality of line contacts between their spiral curved surfaces to thereby seal off and define at least one pair of fluid pockets. The fluid pockets are moved by relative orbital motion of the pair of scrolls. At least one of the circular end plates is provided with an anti-wear plate covering the end surface thereof in the area on which an axial end surface of the opposing spiral element slidably contacts. The circular end plate has a depressed portion at the center portion thereof to define an axial clearance between the anti-wear plate and the central portion of the end plate. Therefore, changes in the axial length of the spiral element due to temperature changes is absorbed by the deformation of the anti-wear plate into the depressed portion.

Abstract: An apparatus for varying the pitch of propulsor blades of a gas turbine engine by eccentrically driven gears. The gas turbine engine includes a rotating structure, an annular gas flowpath coaxial with the rotating structure, a plurality of rotor blades coupled to the rotating structure and extending into the gas flowpath such that a gas stream flowing through the flowpath causes the rotating structure to rotate with respect to the stationary member and a plurality of variable pitch propulsor blades coupled to and disposed radially outwardly of the rotating structure. The pitch of the blade is varied by a pinion gear coaxially coupled to one of the propulsor blades and an internal gear radially disposed about the pinion gear for driving the pinion gear. Annular displacement of the pinion gear causes angular displacement of the propulsor blade with respect to the rotating structure. The internal gear is revolved about the pinion gear whereby the pinion gear is angularly displaced with respect to the rotating structure.

Abstract: A cone shaped body (10) has been inserted into a burner nozzle (9) inside a metal net (11) to provide a burner for lamps that produces better light and a lower sound level. The tip of the cone is pointed against the gas flow to that the gas flowing out of the net is uniformly distributed. This means that the discharged gas at the upper and the lower end of the nozzle have about the same velocity. This uniform gas flow produces a uniform flame about the nozzle which gives a better light and a lower sound level.

Abstract: A method for removing and recovering ammonium nitrogen to avoid nitrate or nitrite formation, and for removing and recovering phosphorous and oxygen-consuming substances (BOD) from leached water, effluent or the like, comprises a pre-filtration step to remove coarse particles and a multi-step filtration process with the filter media and control parameters adapted to provide effective biological, mechanical and chemical purification. During the filtration process the following steps are carried out : (1) peat or a similar biological material with acidifying properties is added during the first step in order to adjust the pH to 5.5, so that ammonia liberation and nitrification are prevented, phosphate solubility is increased and pathogens are killed ; (2) adsorption and cation exchange by the filter medium during the first and second steps is used to bind ammonia and prevent it from being liberated at high pH during the third step ; (3) pH in the third step is adjusted to ca. pH 9 using e.g. dolomite limestone supported a non-degradable material (e.g. mineral or glass wool) in order to chemically bond phosphorous, increase pH to maximise phosphorous bonding in so-called leca beads (or a material with the same chemical composition) and to kill pathogens ; (4) the BOD/nitrogen ratio is maintained at a given level during the first and second steps in order to give optimum heterotrophic bacteria growth and incorporation of ammonium nitrogen into the bacteria cells ; (5) BOD is quickly reduced in a peat filter medium or the like in order to increase enzyme production by the bacteria and therefore increase phosphorous solubility in water, giving improved phosphorous bonding in the third step ; (6) oxygen supply is regulated to give a high microbiological activity, so that most oxygen is used during the first step, giving a low oxygen concentration of less than 4 ppm in order to hinder nitrate formation during the second and third steps, reduce bacterial production and growth in the third step, and reduce the biomass from lysed bacteria to prevent the third step being repeated ; (7) a filter medium with a high surface area for bacterial growth is used during the first and second steps ; (8) the filter medium used during the first and second steps can absorb 20-40 % of its own volume of water in order to give effective biological purification with regards to nitrogen and phosphorous ; (9) a top layer of coarse peat fibres or similar material with a supply of oxygen from the atmosphere to the so-called biofilm, and a bottom layer of finer peat particles or the like with a supply of oxygen to its base from a supply means is used to form the filter medium in the first step ; and (10) the filter medium in the second step comprises a peat material or the like for microbiological incorporation of phosphorous and nitrogen and BOD reduction, in addition to a medium such as bark for increasing pH to provide better bacterial growth conditions.
