Abstract: A valve which is eccentrically adjustable, wherein the eccentric mating between a valve and valve seat is defined by a fixed eccentric and an adjustable eccentric. The fixed eccentric is provided by a drive shaft for the valve closure member being fixed eccentrically of a central axis of rotation of the valve closure member. The adjustable eccentric is provided by a rotatable eccentric bearing for receiving the drive shaft.

Abstract: An articulable joint with two opposing disk-like joint portions or plates which are joined by and pivot about a central locking bolt. The joint portions also engage each other via ball and ball seat contact points. Spring pressed balls on one joint portion are biased into ball seats formed in the other joint portion such that the joint may be pivoted incrementally to a number of positions. The spring pressed balls are separately housed in individual ball plungers which in turn are threaded into its respective joint portion such that the ball plungers are selectively adjustable to vary the amount of turning or pivoting force that is required to unseat the balls from their respective seats and move them to respective adjacent seats.

Abstract: A quick-release adapter for connecting the inlet of an exhaust removal hose to the outlet of a tail pipe of a vehicle with an internal combustion engine while minimizing exhaust leakage. The adapter includes three disk-like permanent magnets pivotably mounted on the inlet of exhaust removal hose and three receptacle-shaped magnetic connectors secured to the outlet of the tail pipe for engaging the magnets and mating the exhaust removal hose to the tail pipe. The exhaust removal hose is thus readily connectable to and disconnectable from the tail pipe.

Abstract: An elbow connection for pneumatic conveying systems is provided. The elbow has an inlet opening, an outlet opening and a curved area of short radius extending therebetween. The section of the elbow between the inlet and outlet openings has a cross-sectional area that is substantially greater, at least 1.5:1, than the cross-sectional area of the inlet and outlet openings to reduce the wear of the elbow wall caused by the material conveyed therein.

Abstract: A vacuum cleaning machine for cleaning and removing industrial wastes, including hazardous waste products, mounted to the chassis of a truck having a collection tank thereon, including a flexible boom coupled to the collection tank and projecting forwardly, with a driver-actuable collection nozzle positioned in front of the truck. An air circulation system, including a blower, is used to draw material through the suction tubes into the collection tank, and a vortex separator removes particulate matter and wet residue from the suction air stream. The air circulation system includes a filter bag housing for removing further particulate matter from the suction air stream, and this is followed by a safety filter for removing the finest particulate matter from the suction air stream.

Abstract: A plate heat exchanger having a plurality of parallel channels for conveying heated gases including entrained pollutants, with transversely directed cooling gases intermediate the polluted gas channels, and an apparatus for periodically cleaning the polluted gas channels, including pipes aligned with their respective channel openings, the pipes having a plurality of jet passages closely spaced therealong, all of the pipes connected to a pressure accumulator having at least a volume greater than ten times the volume of an individual pipe interior, and including controllable valve release mechanisms for sequentially exhausting the pressure tank volume into each of the respective pipes.

Abstract: Apparatus for attachment to the side wall of a hopper or bin, having connections to an extenal source of pressurized air, and having an annular orifice internal to the hopper or bin, wherein the annular orifice is covered by a resilient ring, thereby pemitting the flow of pressurized air outwardly through the annular orifice while protecting the annular orifice from contamination and plugging by materials stored in the bin or hopper.

Abstract: In a system for dust collection and filtering of particulate matter from an air stream, wherein dustladen air is passed through a plurality of bags constructed from suitable effective filtering material so as to collect dust and particulate matter along an internal confined surface of the bag while permitting cleaned air to pass through the bag material, an apparatus for periodically generating an air shock wave which propagates along the bag surface and physically vibrates the bag material. The apparatus includes a plurality of air jets positioned adjacent a bag end in non-axial alignment with the bag, in combination with a circumferential deflection collar surrounding the bag end so as to receive the initial air shock wave and deflect the pressure forces along the circumferential length of the bag.

Abstract: A Venturi apparatus and method used with a cyclone separator to separate particulates, fumes and waste gases from gas, as air. The apparatus has a housing having a generally rectangular chamber through which the gas and particulates flow. The housing has converging side walls forming an elongated rectangular Venturi throat. Plates movably located in the chamber between the side walls are spaced from each other to control the length of the Venturi throat. Controls connected to the plates are operable to move the plates relative to each other to change the length of the Venturi throat. The width of the Venturi throat is determined by the spacing of the side walls and is not changed by movement of the plates.

Abstract: Apparatus is disclosed for insertion into a conveying system line wherein particles are conveyed by a gaseous medium. The apparatus accepts a pressurized gas input and develops therefrom in an internal chamber and annular orifice a gas flow having an internally-directed refluidizing component and a longitudinally-directed conveyor film component.

Abstract: Method and apparatus for treating of waste gases, such as hot-flue gases, to remove therefrom pollutants in the form of solids, such as fly-ash and the like; and also for the removal of chemical substances present in a gaseous form, such as the oxides of sulphur. The solid waste materials, such as fly-ash, are removed from the flue gases by mechanical separation, while the gaseous pollutants, such as sulphur dioxide and/or sulphur trioxide are removed by a scrubbing action with another chemical substance carried in a solution and dispersed by spray action.
