An apparatus and method for feeding and conveying material in a sorted manner in a pneumatic material conveying system, in which at least two material fractions re fed from a feed aperture and conveyed in a channel space further to a delivery end of a material conveying channel by gravity and/or suction Material is fed from at least one feed aperture of at least one input point and a first material fraction is conducted to the channel space and stored temporarily in the channel space or conducted to the outside of the channel space, and material is fed into a feed-in container, in which a second material fraction fed therein is held in temporary storage by a stopper means.

The present subject matter relates to systems and methods for automatically determining the level of an open chute door in connection with a chute system in a building structure. The position of the open door on the chute is automatically determined, without requiring any configuration at each door on the chute, utilizing a daisy chain wire signal connection and a chute busy wire (enable signal) signal connection. Pulses or other signals are counted at a base station to determine the level of the open door.

Methods and system for waste collection and transport systems are provided. Systems of the present disclosure comprise a loading station providing a point of ingress and storage for materials into a larger system. The chute may temporarily house materials. Venting features are provided wherein the chute or load station is provided in fluid communication with an additional component of the system or an exterior environment.

A gravity type debris chute formed by hanging a plurality of corner panels on corners of a structure having horizontal elements, a plurality of side panels and a door panel on the structure with horizontal structural elements so as to form a passage for debris to pass through, wherein each of the said corner panels is folded in the middle so as to form two symmetrical sides, the top of each of said corner panels folded to form a lip or a u fold so as to hang from a structural member, each of said side panels folded at the top to form a u fold or a lip capable of hanging from a horizontal structural member.

Method for feeding in and for handling waste material in the channel section of a pneumatic wastes conveying system, in which method waste material or recycleable material is fed into a feed-in container from the input aperture of an input point of a pneumatic pipe transport system for material and onwards into the channel section between the feed-in container and the material conveying pipe, from where the material is conveyed along with the transporting air via the material conveying pipe to the delivery end of the pneumatic material conveying system, where the material is separated from the transporting air. In the method the material is acted upon by the combined effect of suction and replacement air in the channel section by bringing about compression in size in at least a part of the material being conveyed, by means of an impediment arranged between the conveying pipe and the material to be handled, or against the impediment, before transportation of the material to the delivery end of the pneumatic transport system for wastes.

A collapsible chute for conveying materials with a tubular main body of flexible material with an entrance opening, an exit opening, and a body portion between the entrance and exit openings. A first reinforcing band is fixed to surround the body portion adjacent to the entrance opening, and a first plurality of loops is spaced along the first reinforcing band. A second reinforcing band is fixed to surround the body portion spaced from the first reinforcing band and spaced from the exit opening, and a second plurality of loops is spaced along the second reinforcing band. A third reinforcing band can be fixed to surround the body portion between the first and second reinforcing bands, and a third plurality of loops is spaced along the third reinforcing band. A method for debris removal comprises affixing the entrance opening of the body portion of the main body to an opening of a building structure and evacuating debris through the main body of the collapsible chute.
