Abstract: A cable saw for cutting a workpiece includes a circulating saw cable, a guide device, and a cable storage device and cable tensioning device. The saw cable is driven by a drive and includes a sawing section. The guide device is arranged to move the sawing section along a cutting direction for cutting engagement with the workpiece. The guide device is arranged to allow several movement directions including the cutting direction and at least one lengthening or shortening of the sawing section. The cable storage device and cable tensioning device is arranged for storing, releasing and/or tensioning the saw cable when changing a position and/or length of the sawing section. The guide device includes a lever gear with a pivot lever rotatably hinged to a base holder. The lever gear is arranged to convert a rotational movement of the pivot lever into a movement of deflection rollers—which form the sawing section therebetween—to lengthen and/or shorten the sawing section.

Abstract: A hydraulic rotary drive includes a first rotary drive element and at least two annular pistons connected to the first rotary drive element in a rotationally fixed manner and configured to be axially movable on the first rotary drive element between two end positions. Each annular piston has two annular spur serrations directed away from one another. The hydraulic rotary drive includes a second rotary drive element with ring type serrations that are complementary to the spur serrations of the annular pistons. The hydraulic rotary drive includes a control unit that is configured to control supply of hydraulic fluid to the annular pistons to cause a reciprocating movement of the annular pistons on a shaft in accordance with an operating signal. The hydraulic rotary drive includes a sensor arrangement communicatively coupled to the control unit and arranged to detect the positions of the annular pistons along respective sliding paths.

Abstract: A large manipulator includes an articulated boom that can be folded out. The articulated boom includes boom segments including a last boom segment having a boom tip. The articulated boom includes an end hose and end-hose holder. The end hose is flexible, arranged on the last boom segment, and can be removably coupled to the last boom segment by the end-hose holder. The end-hose holder includes a holding bracket arranged on the last boom segment. The holding bracket is configured to be pivotable into a first pivot position, a second pivot position, and a third pivot position relative to the last boom segment.

Abstract: In a continuous process for the preparation of multiphase soaps, in which stable multiphase soaps are obtained by suitable cutting and stamping of soap masses in various sequences, the individual phases of the multiphase soap are readily visible when viewed from above and from the side.

Abstract: The fluidized bed reactor for biological treatment of effluent essentially comprises a container (1) over the base 2 of which elongated gassing units having gas exit apertures (5) are arranged parallel to one another, in such a way that in each case two neighboring circulating currents (8, 9) in mirror-image symmetry are produced in the reactor. In addition, the reactor (1) is supplied with a retention system (16) arranged on the outside for the separation of carrier particles for biocatalysts suspended in the effluent.
