Abstract: A method for sorting wastes wherein waste or recyclable material is supplied in carrier bags. A sorting apparatus includes a conveyor provided for receiving the carrier bags for separation from each other by guiding the carrier bags into containers according to an allotment. An RFID identifier is connected to each carrier bag. A closing member is provided with the RFID identifier in closing, or as verification of closing. At least one sensor is utilized on the basis of the information read from the RFID identifier of the closing member. At least one handling device, such as a robot, is provided wherein the at least one handling device is controlled to transfer the carrier bags to be sorted from the conveyor into the different allotments on the basis of the information given by the RFID identifiers. The invention also relates to an apparatus.

Abstract: A sensor product web for electric field sensing. The sensor includes a substrate, sequential electrically conductive areas on a surface of the substrate, conductors, an output connected to the electrically conductive areas by one of the conductors, and a via extending through the substrate, forming an electrically conductive path connecting the electrically conductive areas to the output by the conductor on a reverse surface of the substrate.

Abstract: A gate valve, comprising a body (1), a gate element (2), which is movable in the body, transversally with respect to the flow path (3) between at least two positions, i.e. a first position, where the flow path (3) is open, and a second position, where the flow path is closed, and means (4) for moving the gate element (2) between at least said two positions; said gate valve body (1) comprising a first wall element (9) and a second wall element (10) and a space (11) left therebetween for the gate element (2), and an edge part (12), which edge part, when bent, forms a support surface for the first wall element (9) and the second wall element (10) of the gate valve body; in said edge part (12), there is arranged a channel space (13), including at least one opening (14), preferably several openings, which channel space opens into the space (11) left between the first wall element (9) and the second wall element (10) for conducting medium into said space.

Abstract: A method for draining the tank space (20) of a supply tank or feed chute in a pneumatic material conveying system, such as a waste conveying system, of material, such as waste material, in which method the tank space (20) is drained to a conveyor pipe (3) by opening an outlet valve (4), so that the underpressure prevailing in the conveyor pipe, together with the ambient pressure prevailing in the supply tank transfers material from the supply tank to the conveyor pipe (3). In the method, in the supply tank, a wall element (6) positioned at a distance from the outlet aperture (8) of the supply tank and/or from the outlet valve (4), which wall element (6) is arranged to move between at least two positions, i.e.

Abstract: A method for conveying material by applying a pressure difference in a conveying conduit (4), in which method the material is fed into the conveying conduit (4) and in the conveying conduit further into a separating device (5), where the material being conveyed is separated from conveying air, in which method a negative pressure is created in the conveying conduit (4) by means of an ejector apparatus (6), whose suction side is connected to the separating device (5), said ejector apparatus being operated using an operating medium consisting of a liquid mist, especially an aqueous liquid mist, said medium being sprayed through at least one spraying nozzle (122) into an ejector tube (128) directed into a separating element (38). In the method, the generation of the negative pressure to be produced is intensified according to need by limiting the flow of gases, such as air, into the ejector tube (128) from the direction opposite to the spraying direction of its operating medium, i.e.

Abstract: A method in a vacuum conveying system, which vacuum conveying system comprises at least one feed point (61, 66), a material conveying pipe (100, 101, 102) which is connected to the feed point (61, 66) and at the other end to a separator element (20) in which the material being conveyed is separated from conveying air, and means (3, 3) for providing a pressure difference in the conveying pipe (100, 101, 102) at least for the time of conveying the material. In the method, in the conveying piping (100, 101, 102) is provided an intensified vacuum effect (a vacuum pulse) by an ejector device (4), actuating medium of which ejector device is loaded in a pressure accumulator from which it is conveyed to an ejector nozzle for providing an intense suction in the conveying pipe. The invention also relates to an apparatus.

Abstract: A method for closing a filling hole of a waste bin (1), which waste bin comprises a container part (2) and a cover part (3) and at least one filling hole (4) which is formed in a side wall of the cover part (3) and/or the container part (2). Between the cover part (3) and the container part (2) of the waste bin is arranged a retainer part (6), which retainer part keeps the cover part in a first position, whereby a passage via the filling hole (4) to a container space (24) of the container part is open and, after the temperature has reached a predetermined value (T2), the retainer part (6) moves to a second position in which the cover part (3) is released to move with respect to the container part (2) to a second position in which the passage via the filling hole (4) to the container space (24) of the container part is closed. The invention also relates to a waste bin.
