The occurence of corrosion is a potentially major problem for all sprinkler systems. It could cause a problem for the operational reliability as well as for the performance reliablity. It is of course negative for the operational reliability if corrosion causes plugged piping, clogging of control valves or simply non-opening sprinkler heads. All of which may well be the effect of uncontrolled c...

The article presents the results of experiments aimed at finding displacement a cylinder being part boom system, as recorded after initiating rapid breaking process. tests were performed on special test stand which allows modifications control system architecture. comparative analysis three systems different with respect to their architecture and use valves. It discusses influence hydrostatic a...

PURPOSE Bridge anticoagulation therapy is mostly utilized in patients with mechanical heart valves (MHV) receiving warfarin therapy during invasive dental procedures because of the risk of excessive bleeding related to highly vascular supporting dental structures. Bridge therapy using low molecular weight heparin may be an attractive option for invasive dental procedures; however, its safety an...

Modern compressor analyzers enable plant operators to monitor compressors by acquiring and storing pressure changes measured inside the working cylinder, in suction and discharge chambers, furthermore ultrasonic signals and temperatures. The paper focuses on pressure changes inside the cylinder and the possibilities of detecting abnormal operating conditions, in particular valve leakage, by ana...

Abstract Cast engine components are experiencing ever tighter tolerance requirements and at the same time a more complex cast design. The geometries, some of which inaccessible, tested for quality assurance on basis relevant component characteristics, among other things. position check measures actual feature in spatial dimension. Information about alignment geometry combustion chamber cannot b...
