摘要： A filtering device includes a container having an inlet for introducing liquid to be treated, an annular multi-layered prepacked screen assembly (7) provided in the container and having an outlet for treated liquid. The screen assembly includes three or more cylindrical screens (9,10,11) having different diameters and bieng coaxially disposed in the container with their axes extending vertically in the container. An anulus (12,13) is formed between the respective cylindrical screens (9,10,11). Two or more different filter materials performing different filtering functions are filled one in each of the annuluses between the cylindrical screens.

摘要： A device for measuring distance between walls of coaxial cylindrical screens is provided. Rotation of motors 26, 26' is rotated to screw bars 30, 30' and rotation of the screw bars 30, 30' is converted to translational movement of gauge bars 23, 23'. The numbers of rotation of the screw bars 30, 30' corresponding to length of projection of the gauge bars 23, 23' from their withdrawn positions to positions at which they abut against wall surfaces of the screens are measured by rotary encoders 41, 41' and the distance between wall surfaces of the screens thereby is measured. A main body of the device is fixed between the wall surfaces of the screens by means of the projecting gauge bar 23 and a pair of main body supporing units 18, 18.

摘要： A well liner (16) having a selective isolation screen with a limited or less restrictive seal. The well liner (16) includes an elongate base (2) pipe having openings (5) therethrough; surrounded by circumferentially spaced, longitudinal extending spacer bars (3) for forming an inner annulus (7); one or more annular cylindrical sleeves (4) secured to the exterior of the base pipe (2); and a continuous wire wrapping (6) surround the spacer bars (3) except at interrupted areas where the isolated permeable seal sections (10) are placed. The continuous wire wrapping (6) and spacer bars (3) are inverted within the permeable seal sections (10) so that the wire wrapping 6) subtantially fills the inner annulus (9) and a multitude of spacer bars spaced approximately equal to or slightly larger than the spaces between the wire wrapping form the outer most surface of the seal sections (10). The ends of the seal sections (10) are coupled to the wire wrapping (6) screen of the well liner for forming a continuous screen surface and seal.

摘要： A rotary drum type dehydrator includes a rotary drum filter, a suction tube having an inlet and an outlet, said inlet communicating with inside space of the rotary drum filter, a compressed air supply tube connected to the suction tube in a portion thereof downstream of the inlet and communicating with the suction tube and an air compressor connected to the compressed air supply tube for supplying compressed air to the compressed air supply tube. Vacuum is produced in the inside space of the rotary drum filter by supplying compressed air from the air compressor to the suction tube through the compressed air supply tube. A filtered liquid receiving container is provided to collect filtered liquid and the outlet of the suction tube is disposed in the filtered liquid receiving container in such a manner that filtered liquid is jetted out of the outlet of the suction tube and is struck against a side wall of the filtered liquid receiving container or against surface of liquid stored in the container.

摘要： First line element made of, e.g., wire and second line elements made of, e.g., wire are disposed so that they cross each other and they are welded together at crossing points to form a net. The net is pressed to form an undulating net. An undulating net (17-1) of a first layer and an undulating net (17-2) of a second layer are laid one upon the other in such a manner that crossing points of the undulating net (17-1) of the first layer alternately come into contact with and are separated from crossing points of the undulating net (17-2) of the second layer. The crossing points which are in contact with each other are welded together by a welding machine (21). Subsequently, undulating nets of a third to n-th layers are similarly processed to form a three-dimensional net-like structure.

摘要： A filter-heat exchanger (2) includes a plurality of hollow wires (3) arranged in parallel with a slit (4) of a predetermined width formed between adjacent hollow wires (3). The hollow wires (3) each have an inlet and an outlet for a heating/cooling fluid whereby the heating/cooling fluid flows through the hollow wires (3) and fluid to be filtered flows through the slits (4) from one side of the parallelly arranged hollow wires (3) to the other side of thereof. The filter-heat exchanger (2) can accomplish filtering and heat exchanging processes simultaneously in a single step.
