Abstract: A block manifold for a fail safe actuator system allows the actuator operation with a hand pump if electrical power were not available. A method is available to isolate fail safe solenoid valves and an accumulator from a hand pump circuit to relieve the stored energy from the fail safe circuit. An additional set of pilot operated check valves were installed between the motor driven pump circuit and the hand pump circuit. These pilot operated check valves isolated the hand pump circuit from the fail safe dump solenoid and accumulator. These pilot actuated check valves also hold the actuator in the fail safe position as long as the hand pump system was not used. There is also a hydraulic bleed circuit to relieve the accumulator stored energy when the hand pump system was used.

Abstract: A method for cleaning ballast of a track comprising rails extending in a longitudinal direction is executed by means of a ballast cleaning machine having a machine frame supported on on-track undercarriages. The machine includes a cleaning chain with a chain cross member extending perpendicularly to the longitudinal direction. At the start of the cleaning process, an on-track undercarriage situated immediately ahead of the cleaning chain, with regard to a working direction of the ballast cleaning machine, is lifted off the track. The rails are severed, and the track is lifted, after which the chain cross member of the cleaning chain is positioned underneath the track. Finally, the on-track undercarriage is set down upon the track again.

Abstract: An arterially measured pressure signal is continuously read in and temporarily stored in the working memory (RAM). The function p(t) is processed by the central processing unit (CPU), to calculate the heart/time volume PCCO and other hemodynamic parameters. The calculation comprises the following steps: The systemic vascular resistance SVRk is calculated for the current pulse period. The stroke volume SVk is numerically determined from the pressure values of a pulse period, according to the following equation: SV k ? ? ( p i ? ( t ) SVR k + C k ? ( p i ) ? ? p i ? t ) with the compliance C(p)=(MAP?CVP)k/[SVR·<dp/dt>k]·ƒ(p). The difference between the mean arterial pressure MAP and the central venous pressure CVP, and the mean incline of the pressure curve in the diastole <dp/dt>, are re-determined for the current pulse period. The heart/time volume calculated in the current pulse period results from PCCOk=SVk·HR.
