Abstract: A fluid control method includes providing fluid flow through a conduit having a pressure sensitive shutdown valve; driving an electrical power generator with the turbine wheel and delivering electrical power to a storage battery which in-turn powers the components of the system. The method further includes: detecting turbine RPM; calculating volume flow rate from the RPM value and conversion factors input to a computer program. Next, it is determined if average or peak flow rates exceed set point values and creating a shut down signal if it is true so as to close the shutdown valve. A fluid pressure delta is therefore established across the shutdown valve and it is only opened when fluid pressure equilibrium is restored across the valve after break or leak repair and after slowly refilling the downstream system.

Abstract: An apparatus and method for joint music production wherein a remotely separated plurality of musicians are joined by phone lines of a public telephone system. The public telephone system has a signal frequency cutoff limiting transmission to a low range which is incompatible with music. Each of musicians produces a local music signal (MSL) with full audio range. This signal is impressed on the public telephone system which creates a low-end outbound music signal (LEL). Also, separately, the MSL signal is filtered through a first high-pass filter and mixed with a mixer signal to produce a sum/difference signal (SDL). The SDL signal is impressed onto the second phone line of the public telephone system as a high-end outbound music signal (HEL). A second mixer circuit receives at least one remotely produced sum/difference signal (SDR) and the mixer signal and this is again filtered to obtain the high end signal only (HER).
