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) for providing a pressure difference in the conveying pipe (100, 101, 102) at least for the time of conveying the material. In the method, conveying air is monitored with at least one fire detector (500) and, based on the detection, the conveying system is affected by isolating the fire to a certain part of the system and/or by diminishing the conditions of burning. The invention also relates to an apparatus.
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.
A lock ring (6), which comprises a core part (61) and a twisted wire part (62) around it. The lock ring (6) comprises shape memory alloy or bimetal, whereby the lock ring is arranged to deform as the temperature changes to a predetermined value.

METHOD AND APPARATUS IN A VACUUM CONVEYING SYSTEM OF MATERIAL
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.

A waste conveying system in which waste is collected/conveyed, e.g. by a suction system, in a waste container (10) of a regional waste space (16) or a transport container in which/from which the waste is then conveyed to further treatment. The waste space (16) and/or the waste container (10) or the transport container is arranged in a tunnel (20), such as a traffic tunnel, advantageously an underground tunnel, or in its vicinity, or there is a conveying connection from them to the tunnel (20) through which the waste is conveyed away.
A gate valve which comprises a body (101), a gate element (102) which is movable in the body in the cross direction in relation to a flow path (103) between at least two positions, a first position in which the flow path (103) is open, and a second position in which the flow path is closed, and means (104) for moving the gate element (102) between at least two said positions. The gate element (102) comprises a gate part (105) and an actuating body (108) along with which the gate part (105) is arranged to move in a space between body walls (109, 110).

METHOD AND APPARATUS FOR CONVEYING MATERIAL AND EJECTOR APPARATUS
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. from the outlet end (129) of the ejector tube. The invention also relates to an apparatus and an ejector device.
