  • Patent number: 5037536
    Abstract: A vibratory conveying and separating apparatus and a clamping device therefor are disclosed. The apparatus includes a conveyor bed which supports processing screens which convey and separate material being processed. The bed is vibrated in a forward and upward direction at a predetermined forward and upward angle of inclination. At least one releasable clamping device engages between the conveyor bed and processing screen to provide a releasable clamping force against the screen for clamping it to the conveyor bed. The clamp is mounted or positioned to orient the releasable clamping force substantially parallel with the predetermined forward and upward angle of inclination.

  • Patent number: 5037535
    Abstract: In a screening machine comprising two screening frames (13 and 31) each having mutual oppositely located feed and discharge ends on which there is arranged an elastic screening lining (54) and which are caused to oscillate by independent oscillating drives wherein the two screening frames (13 and 31) are associated with each other at different heights in such a way that the lower region of the upper screening frame (31) and the upper region of the lower screening frame (13) lie in a common plane, that the elastic screening lining (54) is secured to the two screening frame (13, 31) in the common plane thereof and that the upper screening frame (31) is independently driven in a circular configuration at the feed end and the lower screening frame (13) is indepndently driven in a circular configuration at the discharge end.

  • Patent number: 4710286
    Abstract: A sieve for powder. The sieve has a housing in which a transverse screen is mounted to divide the housing into upper and lower chambers. Air under pressure carries powder into a cyclone stack mounted on top of the housing from which it is directed onto the screen. A vibrator is connected to the screen to vibrate and thus to assist in the sieving operation. The screen is downwardly inclined and overlying its lower end an inspection cover is mounted in the housing to permit access to the screen for removal for the material which does not pass through the screen.

  • Patent number: 4600506
    Abstract: The invention relates to a screening machine having a multiplicity of mutually parallel transverse supports which are arranged transversely to the transport direction of the material being screened and on or between which a flexible screen plate is fastened. The transverse supports, which are movable relative to one another, of at least two movement systems are driven in such a way that mutually adjacent transverse supports alternately approach one another and move away from one another. The transverse supports move in separate, mutually parallel planes which are at an angle to the planes in which the transverse supports of one particular movement system are located.

  • Patent number: 4356208
    Abstract: The method of riddling wine contained in bottles packed in shipping cases in which the cases are inverted to allow solids to settle into the necks of the bottles, tilting the cases from side to side to jostle the bottles, and vibrating the cases and bottles contained therein, the jostling and vibrating of the bottles serving to dislodge solids in the wine from adherence to the bottles so that the solids settle onto a temporary cap at the outlet of the bottle for disgorging when the cap is removed. The cases of bottles are tilted and vibrated for periods from about ten minutes to about thirty minutes to dislodge solid particles from adherence to the bottle, and the tilting and vibrating is halted for periods from about one hour to about six hours until tilting and vibrating is again effected.

  • Patent number: 4339265
    Abstract: A method and apparatus for treating sewage and converting the sewage into organic fertilizer which utilizes equipment for converting the solid material of the sewage into patties and a mixing apparatus for mixing the patties with bulking agents. The mixture of patties and bulking agents is stored in a pile and subjected to a supply of air to enhance the self-combustion or oxidation of the organic material in the patties. The bulking agents provide the patty-bulking agent mixture with air passages and pockets and minimize compaction of the patties. The self-combustion of the patties continues until the organic material is burned out, leaving a residual ash. A shaker separator having an elongated longitudinal perforated member is reciprocated to separate the ash from the bulking agents. The ash is collected and utilized as organic fertilizer. The bulking agents are recycled back to the mixing apparatus.

  • Patent number: 4256572
    Abstract: A portable loam screening apparatus includes a nearly-square, sloping shaker screen supported by a box-like frame. The frame has a tall end and a short end joined by two sides. Funneling surfaces directed toward the screen are provided along the upper edges of the tall end and the sides. A mixture of coarse material and finer material is dumped onto the shaker screen from the shovel of an excavating vehicle. The coarse material falls from the lower end of the shaker screen outside of the frame, and the finer material passes through the shaker screen to within the box-like frame. The separated finer material is directed to an outfeed conveyer by a hopper or feed conveyor within the frame. The outfeed conveyor extends through one of the sides. A set of wheels mounted to one side of the frame is movable relative to the frame from an operative position for transporting the apparatus to an inoperative position for resting the frame flush on the ground.

  • Patent number: 4224146
    Abstract: In a sifting machine having a driven vibratory screen assembly comprising a so-called sifting basket of which a screen forms the base, the screen is releasably located by a plurality of spaced bars which extend across the screen and project at their ends through side walls of the basket. The projecting end portions of the bars are bolted to external supports on the side walls, and the bars carry spring-loaded plungers which press the frame of the screen against internal ledges on the side walls.

  • Patent number: 4197194
    Abstract: A portable loam screening apparatus includes a nearly-square sloping shaker screen supported by a box-like frame. The frame has a tall end and a short end joined by two sides. Funneling surfaces directed toward the screen are provided along the upper edges of the tall end and the sides. The short end is closed to provide a wall between separated loam and coarse material. A mixture of loam and coarse material is dumped onto the shaker screen from the shovel of an excavating vehicle. The coarse material falls from the lower end of the shaker screen outside of the frame, and the loam passes through the shaker screen to within the box-like frame. The separated loam falls down a sloping table within the frame and can then be retrieved by an excavating vehicle through the open tall end of the frame. A set of wheels mounted to one side of the frame is moveable relative to the frame from an operative position for transporting the apparatus to an inoperative position for resting the frame flush on the ground.
