Abstract: A method for the partial emptying of buoyant objects, which are stored in a loading aid having at least one opening is provided. A processing weight to be partially emptied is established. A fill weight is determined of the objects in the loading aid via a first weighing. The loading aid is at least partially immersed in a liquid bath. The loading aid is positioned or moved for a retention time predefined as a function of the fill weight and of the processing weight in the bath such that there is an on-average constant flow relative to the loading aid and such that the opening is disposed at least partially below a fill level surface of the bath, whereby the objects are taken along by the flow. The at least partially emptied loading aid is lifted out of the bath after the retention time has elapsed.

Abstract: A configuration contains a coupling mechanism for closing a door of a rack store, the door being guided in particular on rails, and an uncoupling and displacing device for opening and displacing the door. The uncoupling and displacing device has a displaceable driver, with which the coupling mechanism can be moved from a closed position into an open position and the door can be displaced. A closure sensor monitors the closed position of the coupling mechanism.

Abstract: A logistics installation for a high-rack storage system has a plurality of conveyor vehicles that travel along a reference track section. A control device is enabled to block a given region of the reference section for travel by a second conveyor vehicle depending on a measured position of a first conveyor vehicle along the reference section. A device for determining a direction of movement of the conveyor vehicles transmits a corresponding signal to the control device. The region that is blocked for the second conveyor vehicle can be established by the control device with regard to the signal representing the direction of movement of the first conveyor vehicle.

Abstract: An optoacoustic sensor for detecting one or more target gases includes a body featuring halves containing measurement cells. Each measurement cell is in communication with a light source and a microphone as well as the ambient atmosphere. Evaluation and control electronics are in communication with the light sources and the microphones sequentially illuminate the first and second light sources so that a measurement signal due to optoacoustic pressure variations from a target gas is generated by the microphone of the illuminated or gas active cell and a compensation signal is generated by the microphone of the non-illuminated or gas inactive cell. The compensation signal is subtracted from the measurement signal by the evaluation and control electronics to provide a sensor output signal.

Abstract: A process for the impact healing of inner discontinuities or defects in the surface area of a cast workpiece where the defects are localized comprises locating an explosive charge on the surface of the workpiece over the inner discontinuities or defects and detonating the explosive charge.

Abstract: An armour plate (1) comprises cavities (2), which are arranged with a plurality of packing bodies (3) in an irregular or regular shape relative to each other. The packing bodies are hollow-bodied, preferably spherical or tubular, and consist of a non-metallic material, preferably glass or ceramic. The interspaces between the packing bodies are filled out with a plastics, preferably a foam made for example of polyurethane.
