Abstract: Apparatus and methods for collection and removal of particulate matter, including fine particulate matter, from a gas stream, comprising a unique combination of high collection efficiency and ultralow pressure drop across the filter. The apparatus and method utilize simultaneous electrostatic precipitation and membrane filtration of a particular pore size, wherein electrostatic collection and filtration occur on the same surface.

Abstract: The penile traction device includes a preferably reusable or disposable foam pressure dissipation friction pad having a preferably felt-like backing positioned around the penile shaft for dissipating applied force and frictionally holding the device to the shaft. A weight supporting means has a strap that surrounds and transfers force to the pressure dissipation friction pad. The weight support strap receives force from a selective weight means. A resilient and/or shock absorbing connector can be placed between the weight support means and selective weight means. A two-section weight relief means is also connected to the selective weight means. A handle on the relief means allows the patient or attendant to manually lift all or a part of the weight from the weight support means. The two sections of the relief means are adjustable to vary the overall length of the relief means.

Abstract: A device and method for controlling particulate air pollutants of the present invention combines filtration and electrostatic collection devices. The invention includes a chamber housing a plurality of rows of filter elements. Between each row of filter elements is a grounded plate. Between the grounded plates and the filter elements are electrode grids for creating electrostatic precipitation zones between each row of filter elements. In this way, when the filter elements are cleaned by pulsing air in a reverse direction, the dust removed from the bags will collect in the electrostatic precipitation zones rather than on adjacent filter elements.

Abstract: A method of improving control of atmospheric emission of particulate matter from the emission stack of coal combustion facilities which employ baghouse particle controllers is disclosed. The method involves injecting upstream of the baghouse a small but conditioning effective amount of ammonia gas and sulfur trioxide in sequence. When this is done, the pressure drop across the baghouse is less and the amount of particulate matter in the smoke stack emissions is reduced by significant amounts.

Abstract: A downhole pump filter filters sand and other solid particles from well fluids prior to passage of the fluids through the intake nut of a well pump. A cylindrical coupling has an externally threaded upper end which coaxially screws into the pump intake nut. The coupling also has an externally threaded lower end. A tubular member coaxially secured within the lower end of the coupling has a plurality of perforations dispersed at least along its lower portion. A filter sock may encase the perforated portion of the tubular member to block smaller sand or other solid particles from entry into the tubular member perforations. A cylindrical casing with a closed lower end and an internally threaded upper end coaxially screws onto the exxternally threaded lower end of the coupling with the tubular member and the filter sock disposed within the casing. The casing has a plurality of perforations dispersed at least along its lower poriton.

Abstract: Apparatus is disclosed for making ends for metal or composite can bodies, which ends are first partially formed in a press to a cup-shaped configuration including a peripheral skirt and are then fed to a curling machine in which the skirt is contoured to facilitate application of the end to a can body. The press has a vertically reciprocable slide or slides which, together with an opposed portion of the press frame, support pairs of cooperable dies for blanking and partially forming can ends from sheet material fed horizontally into the press. Thereafter, the partially formed can ends are displaced into a horizontal plane vertically spaced from the sheet feed line, and a kicker member associated with each die set is operable in coordination with slide movement to impact against and propel the partially formed can end laterally and into a guide chute leading either to a curling machine or to an endless conveyor by which the partially formed can end is delivered to a curling machine.

Abstract: Apparatus is provided for forming a chime bead adjacent the closed end of a seamless cup-shaped metal can body and a plurality of peripheral beads intermediate the opposite ends of the can body. The apparatus includes a plurality of beading spindles receiving and supporting can bodies for movement along an arcuate path. The beading spindles are provided with beading tool portions corresponding to the chime and intermediate beads to be formed on a can body. The frame supports axially offset and sequentially arranged outer beading rails positioned along the arcuate path of spindle movement. During movement of the spindles along the path between input and output stations of the apparatus, can bodies on the spindles are rotated about the spindle axes and, as each can body moves past the outer beading rails, the beading tool portions of the spindles and the outer beading rails cooperatively engage a can body therebetween to sequentially form first the chime bead and then the intermediate beads on the can body.

Abstract: Apparatus is disclosed for detecting flaws in sheet material of the character which increase the surface height of the sheet material. The apparatus includes a pair of horizontally parallel driven lower rolls and three upper rolls each mounted on a corresponding pivotal bracket. Two of the upper rolls are associated with one of the lower rolls and are axially spaced apart therealong, and the third upper roll is associated with the other lower roll and positioned therealong to span the space between the other two upper rolls. Each of the upper rolls is rotatably supported by the corresponding bracket for pivotal movement toward and away from the lower roll. Each upper roll bracket is provided with a pair of adjustable stop screws, one adjacent each of the opposite ends of the corresponding upper roll, and each adjustable stop screw carries a switch actuator screw which is adjustable relative to the stop screw.

Abstract: An article transfer mechanism is provided comprising parallel spaced apart feed plates reciprocable in the direction between the opposite ends thereof and carrying a plurality of laterally opposed article engaging feed finger members. Each feed finger member is supported for reciprocation laterally relative to the corresponding feed plate, and the feed plates support corresponding cam rods displaceable therewith and relative thereto in the direction of reciprocation of the feed plates. A cam and lever arrangement reciprocates the feed plates to displace the feed finger members longitudinally, and a second cam and lever arrangement reciprocates the cam rods to displace the feed finger members laterally inwardly and outwardly relative to the feed plates.
