Successive Compressions From Different Directions Patents (Class 100/42)
  • Patent number: 4315459
    Abstract: A baling machine comprises a frame defining a first baling chamber having an open top and an opening formed in one end and a second baling chamber which communicates with the first baling chamber through the opening. A cover member is pivotally mounted on the frame and movable between an open position permitting access into the first baling chamber through the open top and a closed position covering the open top. A feed hopper is mounted on the frame for introducing material to be baled into the first baling chamber. A first compression ram is mounted adjacent to the first baling chamber and is movable into the first baling chamber for compressing the material in the first baling chamber and for thereby forming the material into a block having one end section which is aligned with the opening. A feed ram is mounted adjacent to the first baling chamber and is movable into the first baling chamber for moving the block end section into the second baling chamber through the opening.

  • Patent number: 4273581
    Abstract: A mass of particulate material is sintered or densified by applying a first pressure to the mass in a first direction, applying a second pressure to the mass in a second direction which is transverse to the first direction, and applying a third pressure to the mass in a third direction which is transverse to the first and second directions. The first, second and third pressures may be successively modified while the mass is heated to a sintering temperature.

  • Patent number: 4253388
    Abstract: A method for compressing and cutting random loaded scrap metal comprises the steps of gravity advancing scrap metal to a cutting zone, applying a first transversal compression to the scrap metal being advanced, guillotine cutting a portion of the scrap metal and concurrently applying a further transversal compression. The machine comprises a scrap metal conveying trough, a transversally movable pressing plunger adapted for traversing the conveying trough and compacting the conveyed scrap metal, a guillotine block for cutting the compacted scrap metal and a guillotine driven compacting block movable perpendicularly to the pressing plunger and cooperating therewith.

  • Patent number: 4132163
    Abstract: If the next charge to be stuffed into the baling chamber has not yet reached the desired size and density by the time the stuffing fork and compacting plunger are ready to begin their next operating cycles, the plunger and the fork are temporarily deactivated until the charge reaches full size and density. Thereupon, the fork stuffs the entire charge into the baling chamber in a single cycle of operation for compaction by the plunger. The baler is loaded from the bottom of the baling chamber through an upwardly curved duct that serves both as an accumulating chamber and as a pre-compression area into which the charge is progressively packed by a rotating, retractable finger drum at the lower end of the duct. The plunger closes the top of the duct during such accumulation and pre-compression, and in order to provide ample time for the plunger to retract from the duct when the stuffing cycle commences, the fork moves slowly at first but then quite rapidly once the plunger has retracted.

  • Patent number: 4099457
    Abstract: A device for discharging refuse through a discharge pipe being in communication with a hopper having an outlet through which refuse is successively introduced into the discharge pipe from a vacuum transport system performs the following operations:A compactor gate is advanced into the discharge pipe in a direction perpendicular to the length dimension of the discharge pipe at a location between the hopper outlet and a discharge outlet to block the internal longitudinal passage thereof to substantially prevent air from being drawn into the vacuum transport system through discharge outlet and the hopper. Thereafter, a compactor pusher is repeatedly reciprocated in the discharge pipe from a withdrawn limit position in which communication between the hopper outlet and the discharge pipe is open, towards the lowered compactor gate to accumulate and compress successively introduced refuse between the compactor pusher and the compactor gate.

  • Patent number: 4092247
    Abstract: Process for dewatering thickened sludge comprising the steps of depositing thickened sludge onto a porous support, partially dewatering the thickened sludge by establishing a vacuum within said porous support, compressing the partially dewatered sludge on said porous support at a pressure of from 1 to 10 kp/cm.sup.2 to further dewater the sludge and to form a sludge cake, compressing the sludge cake on the porous support at a pressure of from 10 to 300 kp/cm.sup.2 to further dewater the sludge cake and discharging the dewatered sludge cake from the porous support.

  • Patent number: 4086850
    Abstract: A scrap compactor has a generally parallelepipedal elongated chamber. The top wall of the chamber may be pivoted down to partially crush the scrap, and a lower portion of one of the side walls of the chamber may be pivoted inward to similarly precompress the scrap. After swinging-in of the lower portion of the one wall this wall is swung outwardly and the opposite wall is moved in while remaining parallel to the other wall. Thereafter the fully compacted scrap may be pushed out an outlet hole in one end of the press.

  • Patent number: 4075942
    Abstract: In a bale press feeder, waste material is drawn into a condenser to form a fluffy blanket. The thickness of the blanket is decreased by passing the blanket through rolling devices with successively reduced clearance, and then by drawing the blanket through a chamber of successively reduced height by a conveyor belt. The thereby compressed blanket is fed to a bale press. A packer, operated in response to the feeding of the compressed blanket to the bale press, cyclically packs the blanket in the press.

  • Patent number: 4018169
    Abstract: A frame having a baling chamber formed therein and a feed hopper member pivotally mounted adjacent the chamber for introducing a car body or similar article partially into the baling chamber. A cover member is pivotally mounted adjacent the other side of the baling chamber and has a front edge constructed as a cutting edge. The cover member when pivoted to its open position permits the introduction of the car body into the baling chamber by tilting the feed hopper member. The cover member, when pivoted to its closed position after the car body is partially introduced into the baling chamber, will partially crush and bend the car at approximately the middle portion thereof so that substantially one-half of the car body will be inside the baling chamber and the other half will protrude out of the baling chamber through the space adjacent the front edge of the cover member.

  • Patent number: 3965812
    Abstract: This invention is directed to an apparatus and method wherein relatively large bulky pieces of scrap metal can be, substantially, simultaneously, divided or separated into smaller pieces of scrap metal and then compressed into smaller and more dense units of scrap metal. In compressing the bulky scrap metal into smaller and more dense units of scrap metal, the grade and quality of the scrap metal is increased so as to be more, economically, valuable.
