Abstract: The magnetic separator has a tank with a pair of dual conveyor chains, spaced apart, at opposite sides of the tank. A plurality of frames with spaced apart magnetic rods are suspended from the conveyor chains in a manner allowing the frames to swivel and always hang vertically as the chains traverse their endless path. The liquid in the tank flows through the frames and ferrous particles are attracted to the magnetic rods. The rods are cleaned and the ferrous particles removed at a wiping station. Each frame has a scraping edge which contacts the bottom of the tank and drags out the non-magnetic particulate which has separated from the liquid.

Abstract: A heat exchange has a main body and a drive shaft in the main body. There is a motor to drive the drive shaft. A rotor is mounted on the drive shaft and has a central hub. Pairs of spaced blades extend radially from the hub to an outer chamber, attached to the outer ends of the blades. There are openings in the hub to communicate a blade with the hub interior and openings in the outer chamber communicating the outer chamber with a blade. There are closure plates at each end of the main body having pairs of inlet/outlet openings. A valve plate between the rotor and each end plate defines gas pathways between on opening and a first end plate and another opening in the second end plate. There are two gas pathways through the apparatus. In the first pathway gas enters an inlet in the first end plate, passes through a valve plate, over the blades of the rotor, through a second valve plate to an outlet of the second end plate.

Abstract: An apparatus for filtering industrial process liquids is disclosed herein. The apparatus includes a tank, a continuous conveyor screen mounted within the tank, a partition spanning the tank walls and having an elongated aperture therethrough, and media sealing means upon and surrounding the aperture. One side of the conveyor screen overlies the tank and is guidably retained for sealing engagment with the sealing means, and the other side of the conveyor screen operatively engages a continuous sheet of filter media. The conveyor screen and filter media span the aperture providing upon the underside of the partition an enclosed filtered liquid reservoir and upon its other side an open unfiltered reservoir. An elongated open-top vacuum chamber is supported within the filtered liquid reservoir with its peripheral edge in sealing registry with the conveyor screen and having a first outlet for delivering filtered liquid to a process area.

Abstract: A heat exchanger fan having a hollow central shaft. Hollow blades are formed on the central shaft and a peripheral flange is attached to the distal ends of the hollow blades. The interior of the shaft communicates with the interior of the blades, and openings at the distal ends of the blades extend through the peripheral flange.

Abstract: An apparatus for filtering industrial processing liquids is disclosed which includes a tank, a continuous conveyor screen positioned in and defining a loop in the tank, and a continuous filter media placed on an outer surface of the conveyor. The apparatus includes a power operated tractor chain sludge elevator guidably mounted within the tank extending along and frictionally engaging an outer surface return portion of the filter media for effecting a positive upward lift movement of adjacent portions of the filter media with accumulated sludge thereon. The apparatus may also include an apertured horizontal partition in the tank, the filter media sealed over the aperture defining a filtered liquid reservoir chamber positioned below the partition and an unfiltered liquid chamber above the partition, an opened-top vacuum chamber sealed to the filter media and immersed within the filtered liquid chamber positioned within the aperture so as to form a peripheral channel between the aperture and vacuum chamber.

Abstract: A method of consolidating metal powders selected from the group consisting essentially of aluminum, aluminum alloys, and aluminum metal matrix composites includes: pressing the powder into a preform, and preheating the preform to elevated temperatures; providing a bed of flowable pressure transmitting particles; positioning the preform in such relation to the bed that the particles encompass the preform; and pressurizing the bed to compress the particles and cause pressure transmission via the particles to the preform, thereby to consolidate the body into desired shape. Typically, the metal powder has surface oxide, and such pressurizing is carried out to break up, partially or fully, the surface oxide.

Abstract: A method of treating a preform consisting essentially FeNeB alloy particles to produce a magnet having superior magnetic properties, the steps:(a) removing O.sub.2 from the preform and applying an O.sub.2 resistant coating to the preform surface, or removing O.sub.2 and maintaining an O.sub.2 -free environment,(b) heating the coated preform to elevated temperature and in a non-oxidizing atmosphere, to facilitate subsequent bonding of the particles during their consolidation,(c) providing a consolidation zone containing a grain bed and transferring the heated and coated or uncoated preform to said zone to be embedded in the grain bed,(d) applying pressure to the grain bed sufficient to be transferred via the bed and to the heated preform, thereby to consolidate the preform.
