Abstract: A suction particle detection system having a wall or ceiling feed-through (100) for fluidically connecting a pipe or hose end (200) to a test environment (300), the wall or ceiling feedthrough (100) comprising a line portion (110), which has a first line end (111) for fluidically connecting to the pipe or hose end (200) of the suction particle detection system and a second line end (112) arranged opposite the first line end (111), wherein the second line end (112) is formed with a suction opening (113), having a fastening means (120) for fixing the wall or ceiling feedthrough (100) within a feedthrough opening (320) of a wall-like or ceiling-like room structure (310), and having a flange-like collar portion (114), which extends starting from the second line end (112) in the radial direction, the fastening means (120) having one or more deflectable springs (121).

Abstract: An order-picking storage system for picking orders, in particular of articles in containers, includes at least one container store and at least one order-picking workplace. The containers are supplied from the container stores to at least one order-picking workplace and are provided there in straight-through channels and/or in variable-use stations in a plurality of removal positions. A conveying device transfers the containers supplied from the container store to each straight-through channel and/or variable-use station. The straight-through channels and/or variable-use stations and the order-picking workplace are arranged in the upper region of the container store. The storage system thus provides a time-saving and staff-saving order-picking storage system with a high utilization of space, and provides a compact, ergonomic and attractive workstation.

Abstract: In this method and apparatus for the wireless control of a lift device and, in particular, of a traveling crane, a plurality of transmitting units communicate by infrared transmission of data telegrams to a receiving unit associated with the crane. The data telegrams include an integrated address signal that is unique to each transmitting unit and is stored in a memory module of the transmitting unit. The receiving unit decodes the data telegram and, if the crane is not then in use, stores the address signal in a comparison circuit of the receiving unit. Only subsequently-received data telegrams incorporating the stored address signal are passed to the crane for controlling the crane, thereby assuring that a user not then in control of a crane operation cannot interfere with its operation.

Abstract: The invention refers to a load test apparatus for hoisting units by means of strain gages, where the test data affect the transmission of a hoisting unit motor. That is, a load test cell is positioned between the fixed support for the hoisting unit and the hoisting cable. The cell is mounted with an upper bolt connecting it to the fixed support and a lower bolt connecting it to the fixed support and the hoisting cable. In the area between the two bolts the flat cell is of restricted cross section and test gages are mounted here to monitor tensile forces in the cell according to the load. The gages are connected, in turn, through a bridging circuit incorporating resistances to the hoist drive. Because of the simplicity and size of the test structure, it can be manufactured economically by simple mass production techniques.
