摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
