  • Patent number: 5544983
    Abstract: A method of transferring material from the bottom of a body of water provides a first tank submerged at a predetermined depth above the bottom. A material source is provided at the bottom subject to ambient water pressure, and is fluidly connected with the first tank. Material is transferred from the material source to the first tank by reducing the pressure in the first tank below the ambient water pressure at the predetermined depth. The ambient water pressure at the bottom thus forces the material into the first tank. Material is transferred from the first tank to a second tank under the force of compressed air until the first tank is substantially empty of material and full of compressed air. The first tank is connected to a third tank and an air compressor, the material transfer from the first tank to the second tank taking place by the compressor transferring compressed air to the first tank from the third tank.

  • Patent number: 5535791
    Abstract: A container (1) for masses (17) which can be pumped and which flow freely consists of a sack-shaped bag (3) made of flexible, diffusion-impervious plastic sheet which is closed pressure tight and arranged in a holding frame (2). From a bottom area (9) of bag (3), a conduit (11) to which an intake conduit (13) can be coupled emerges from the bag's discharge opening (10), which can also serve as a filling hole. During removal of mass (17) from the bag (3), the latter is progressively raised by a hoist (16). In this way and under the action of the reduced pressure prevailing inside the bag (3), the latter assumes an increasingly slimmer pear shape. In this way, the mass (17) accumulates in the area of the mouth of the conduit (11), and the mass (17) can be completely removed from the bag without difficulty and without air inclusions. In order to laterally support and protect the bag (3) when it is full, a holding frame (2) has a wall (5).

  • Patent number: 5478172
    Abstract: Ultrafine powder is stored in a pneumatic transportation tank (20), and is discharged to a transporting conduit (23) while being fluidized by the pressurized air fed through a fluidizing air port (24). The ultrafine powder is fed to a weigher (30) provided at the other end of the transporting conduit (23), at which the weight of the transported ultrafine powder is weighed by a load cell (31). After the weighed value reaches 90% of a predetermined value, the fed amount of the pneumatic transportation air is reduced, and a bypass regulating valve (38) is adjusted to thus decelerate the transportation. When the weighed value reaches 100% of the predetermined value, the discharge of the ultrafine powder to the transporting conduit (23) is stopped. This method and the apparatus enable the storage, quantitative batch transportation, and automatic weighing of the ultrafine powder such as silica fume.

  • Patent number: 5236285
    Abstract: A high pressure transfer device for feeding wood chips to a digster in the production of paper pulp has enhanced efficiency. A pocketed rotor is mounted for rotation in a housing having first through fourth ports, with a screen at the third port for screening wood chips out of liquid passing through that third port. This screen is blanked at the leading edge in the direction of rotation so that as a pocket rotates into operative association with the first and third ports, the pocket inlet has an arcuate extent of about two inches which is exposed to the first port --large enough to allow chips to start flowing freely into the pocket--before the outlet of that pocket is exposed to a suction source in communication with the screen.

  • Patent number: 5199767
    Abstract: Heavy media, which are heavier than the bulk density of nodules of raw deepsea mineral resources, are used to discharge the nodules on a marine ship through a lifting pipe from a sea floor U-tube connecting with a downstream pipe laid to the deepsea bottom, by operating a piston pump on the marine ship. The heavy media are fed through the downstream pipe, and when nodules mined at the deepsea floor, mainly manganese nodules and cobalt-rich crusts which contain useful heavy metal, are fed into the sea floor U-tube through feeding devices, the nodules are continuously lifted with the heavy media through the lifting pipe from the sea floor to the marine ship, by buoyant force yielding from the heavy medium. This method requires much smaller power consumption than any conventional method of lifting nodules.

  • Patent number: 5170949
    Abstract: An economical apparatus and method for reprocessing scrap film. The apparatus includes a film-air separation chamber for separating air from incoming strips of scrap film, a cutter for cutting the strips into fine pieces, and a storage tank or further reprocessing means to which the cut pieces of scrap film are conveyed. A air bypass line having a computer-controlled valve conveys air directly from the film-air separation chamber to the cutter outlet when the valve is in an open position, and causes all of the air to flow into the cutter inlet when the valve is in a closed position. The open or closed position of the air bypass valve depends upon the cutter motor power, which varies as the volume of scrap film in the cutter varies. Due to the inclusion of the accurately controlled air bypass valve, only a single fan is needed to convey the film into and out of both the film-air separation chamber and the cutter.
