  • Patent number: 6745682
    Abstract: A device for draining liquid from canned goods includes a compression lever pivotally connected to a base lever. The base lever includes a support surface extending between opposed ends for tabletop use. The base lever includes an end wall perpendicular to the support surface. The compression lever is pivotally coupled to the end wall. A handle is attached to the base lever at its free end, a can receiving section being defined between the handle and end wall. The device includes a piston having a perforated disk and connected to the compression lever in a ball joint/socket relationship. Therefore, a can may be positioned on the can receiving section and the compression lever and piston operated to drain liquid from the can. Multiple socket positions and pivot point configuration provide for a maximum leverage ratio while the support surface configuration allows for stable, one-handed operation of the device.

  • Patent number: 6684764
    Abstract: An apparatus for removing liquid from a composite mixture of liquid and solids comprises a hopper mounted atop a compactor ram assembly. A snout section and an extruder section are mounted axial to the compactor ram assembly. A hydraulically-operated ram compresses wet material into the snout and extruder sections. Under pressure from the ram, liquid in the waste material escapes from drainage holes in the snout section top, bottom, and sides, and the extruder section top, bottom, and sides. A platen, pivotally mounted to the extruder top plate near the exit of the device and biased with a constant pressure, controls the back pressure in the extruder and snout sections. The apparatus has an extruder section and snout section of the same constant cross section and coaxial with each other. In a second embodiment of the apparatus, certain of the walls may diverge to further facilitate access to the first platen through the exit opening.

  • Patent number: 6241900
    Abstract: According to a waste water treatment method and apparatus of the present invention, a permeable sheet 3 is fed into a treatment tank 2 in which a stream is formed. The waste water, which flows downstream, is caused to pass through the permeable sheet 3, while the permeable sheet 3 travels in the treatment tank 2 so as to traverse the surface of the waste water on a downstream side in the flowing direction of the waste water. Therefore, not only the sludge in the waste water but also the oily substances floating in the waste water can be collected and removed because they cling to the permeable sheet 3 and are gathered by it. As a result, a waste water treatment tank 2 and the like can be maintained in a usable state for a long time. In addition, there can be obtained a treated water to which microbial treatment can be applied.

    Abstract: In a method and apparatus for removing water from sludge the sludge is introduced into an intermediate chamber from which it is fed into at least one sludge chamber having a filter surface. A hydrostatic pressure is built up in the sludge chamber to remove the water. The sludge chamber is then opened and the filter surface moved out of the sludge chamber to remove the filter cake. The hydrostatic pressure is generated by the sludge being transferred out of the intermediate container, after the continuous feed of sludge thereto has been cut off, by positive displacement of the volume of sludge from the intermediate container into the sludge chamber. The feed of sludge into the sludge chamber may occur simultaneously at a plurality of points from a corresponding number of intermediate containers.

The first stage extracts soy milk from soybean go, and comprises a cylindrical pot, a cylindrical filter for receiving go held within the pot, there being an annular gap between the filter and the pot, a wire cloth disk movable within the filter, the disk having a circumferential seal for sealing between the edges of the disk and the sides of the filter, and a press assembly for urging the disk downwardly within the filter, whereby soy milk is extracted from the go, passes through the filter and into the annular gap. The soy milk is cooked in the pot. A solidifier is added while a second stage of the apparatus of the invention creates a gentle turbulence within the soy milk. After the soybean curds are formed, the third stage of the invention compresses the curds into tofu. The third stage comprises a form having openings for escape of whey which fits within the pot.

  • Patent number: 5590590
    Abstract: An implement for separating the liquid medium from the solid contents of canned foodstuffs, e.g., canned tunafish, having two arms pivotally connected by a hinge, e.g., a pivot pin, one arm ending in a compression plate and the other arm ending in a can receptacle, one or both arms being bent to allow substantial alignment of the compression plate and can receptacle, is described. The opposite ends of both arms are handles; and the compression plate is sized so as to fit into the can containing foodstuffs and allow liquid to escape therefrom when the contents are compressed. The thickness of the compression plate is also sized so that a portion protrudes from the top of the can after the contents thereof have been compressed, so that it can be used to strike a solid surface, generating a further compressive force.

  • Patent number: 5501144
    Abstract: A hand held press used to remove the liquid packing fluids in a can of food by biasing the lid of the can against the contents of the can. The press includes an upper pressing element and a lower pressing element. The upper pressing element has a perforated region that acts as a strainer. The perforated region is advanced against the lid and into the can, wherein displaced packing fluids are collected within a receiving area defined within the perforated region. A pour spout then allows the collected fluids to be removed in a controlled manner. The lower pressing element retains the can in a predetermined orientation as the can is being pressed. Accordingly, the angle at which the displaced fluids will pour is controlled by the manipulation of the press and the can of food held firmly within the press.

  • Patent number: 5462425
    Abstract: An apparatus for mechanically separating water from coal includes a vibrating hopper, two contra-rotating cylinders, a solid collector, and a fluid collector. The hopper feeds hydrated coal or coal slurry to wells which are arranged along the surface of a first rotating cylinder. A second rotating cylinder has protrusions on its surface which are precisely placed such that when the first and second cylinders are brought in contact and rotated in contra-rotating directions, each of the wells of the first cylinder and a corresponding protrusion of the second cylinder form mating female and male dies. Coal in the female dies is pressed, and the moisture in the coal is squeezed out. The coal remaining in the dies is then delivered to the solid collector via a pusher. The distance between the cylinders may be varied through adjustable cylinder bearings or pillow blocks. Both the male and female dies may be removed and replaced.

  • Patent number: 5391069
    Abstract: A metal shavings and chips compactor for extruding oil from metal chips and shavings and compacting the metal into easily transportable pellets. A compactor cylinder contains a piston and has an opening through which an auger feeds metal chips and shavings. A gate closes an end of the cylinder. A first hydraulic drive drives the piston under low pressure to close the opening and apply a first compacting pressure on the metal to form a loosely compacted pellet in the cylinder. High pressure then operates the piston to form a compact metal pellet substantially void of interstices. A second hydraulic drive opens the gate; the piston is operated at low pressure to discharge the compact metal pellet from the chamber and oil is collected below the cylinder. The compacting pressures are achieved through mechanical advantages provided by the size of the piston to that of the first hydraulic drive.
