Abstract:
A material handling system for the disposal of materials in multi-floor buildings. The material handling system has one or more main chutes each having one or more sets of loading stations, queue chutes, and gates. The queue chutes store material to be disposed, which is held back from entering into the main chute by the gate. The material is loaded into the queue chute via an opening in the loading station. The opening of the gates is controlled using a material handling system controller, which is controlled via a control panel or automatically using a timer or based upon the output of one or more level sensors that can determine the fullness of the queue chutes. The main chutes can have primary gates to allow for safe maintenance of the system. The loading stations can have secondary access to the main chutes.

Abstract:
A new process and new device permit the repair of damaged pipes in which debris formation occurs or in which pipe sections are completely destroyed. The device can be mounted on a pipe-repair robot or on a conventional chariot and remote-controlled by a television camera. A noble metal lining (1) is introduced into the pipe interior by the device, which is equipped with a simple locking mechanism (4). The lining is then pushed to the site of damage or of a missing pipe section and a sealant is forced through holes in the lining toward the exterior.
Abstract:
Method for feeding in and conveying material in a pneumatic material-conveying system, in which method material (w) is fed into the channel space (10) of the material conveying channel (1 ) via a number of input apertures (20) of input points (2) that are at a vertical distance from each other and is conveyed in the channel space onwards to the delivery end of the material conveying channel mainly by means of gravity and the suction brought about by the partial-vacuum generators of the pneumatic material-conveying system. In the material input phase, the displacement in the channel space (10) of at least most of the material (w) fed in from higher up to the point in the channel space of a lower input point is prevented with an arresting means (31 ) arranged in the material conveying channel, between the input aperture (20) of the input point (2) situated higher up and the input aperture of a second input point below it, in which case the material collects in the input phase in the channel space (10) supported by an arresting means (31 ), and that in the material conveying phase the connection from the suction side of the partial-vacuum generator of the material conveying system is connected to the material conveying channel (1 ), the arresting means (31 ) is displaced from the first position into the second position in such a way that the material (w) that was supported by the arresting means (31 ) is able to displace in the channel space (10) of the material channel towards the delivery end of the material conveying channel (1 ). The invention also relates to an apparatus.
Abstract:
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 (10) from the input aperture (2) of an input point (1) of a pneumatic pipe transport system for material and onwards into the channel section (20, 21, 22) between the feed-in container and the material conveying pipe (100), from where the material is conveyed along with the transporting air via the material conveying pipe (100) to the delivery end of the pneumatic material conveying system, where the material is separated from the transporting air. In the method the material (w) is acted upon by the combined effect of suction and replacement air in the channel section (20, 21, 22) by bringing about compression in size in at least a part of the material (w) being conveyed, by means of an impediment (30) arranged between the conveying pipe (100) and the material (w) to be handled, or against the impediment, before transportation of the material to the delivery end of the pneumatic transport system for wastes.
