Abstract: A device for telecommunication comprising alarm devices or the like, installed in secured areas (2) such as apartments, vacation or private homes, company buildings, shops, banks, insurances and the like, has a central unit (3), which is associated with an alarm device disposed in a secured area (2) and to which surveillance or sensor units (3) are connected, and an internet portal (7), which is hosted on a server and contacted by the central unit (4) in case warning signals are received from the associated surveillance or sensor units (3). The internet portal allows for communication means (9) to contact a person (1) associated with the respective secured area (2). The internet portal can be accessed by the person (1) with a key or password.

Abstract: A continuous-operation extraction apparatus for strip mining that is self propelled on continuous track treads. A cylindrically-shaped cutting extractor has cutting tools arranged on its peripheral surface. Recesses are provided in this peripheral surface for the transfer of extracted material through a chute to a first conveyor that is located axially within the cylinder of the cutting extractor. A second conveyor having loading carts connects with the first conveyor and receives the loosened material from the first conveyor. The first conveyor has an inside section which emerges from a front side of the cylinder and merges outside into a sloping conveyance section which extends vertically to substantially an upper edge of a chassis. An overhead ascending section is connected to the inside section and terminates in a transfer region where the extracted material is transferred to the second conveyor.

Abstract: An en-mass conveyor for vertically or steeply lifting bulk material has two, primary, flat, endless belt conveyors which are vertical or steeply-inclined throughout facing, correspondingly-progressing, material-conveying runs thus forming a belt shaft. One of the primary belts has flights or similar impellers which extend to the other belt in the belt shaft. Two, secondary, endless, flat belts laterally close the belt shaft along with one or two side or closure walls which are vertically immovable and provided with an opening for laterally feeding of the bulk material into the belt shaft for conveyance.
