A hot water recovery system includes a hot water source; a hot water delivery line connected between said hot water source and at least one plumbing fixture along with a cold water delivery line connection between said plumbing fixture, a cold water source and said hot water source; a pump,...
A purge valve comprising a valve body having a valve inlet and a valve outlet and a water flow passage between the valve inlet and the valve outlet; first valve means adapted to set
These investigators did not observe the rapid decay of turbulence after the intake valve closed since the recirculating flows in the cavity persisted much longer than the lifetime of a characteristic eddy. A basic experiment in which probe position in the engine is varied is necessary to check ...
was used to strip ethanol from the recirculating fermentation broth with the aim of maintaining ethanol concentrations below toxic levels. Fermentation broth was constantly circulated between the two vessels, while the conditions of the fermentation broth and condensed...
Finally, the mem- brane was washed with sterile distilled water prior to use. The average bubble size could not be measured optically at the appropriate conditions as the fermentation liquid was opaque, thus the bubble size was assumed to be the same as in our previous studies [17]. One ...
An apparatus is shown for attachment to a plumbing system for the rapid on-demand delivery of hot water through the plumbing system to an ultimate point of use. The apparatus includ
The period in which the base liquid 14 is recirculating in the divert loop 32 may be effectively used by the system operator to provide for any of a number of necessary operations to the system 110. For example, maintenance tasks of the system downstream of the divert junction, that is the...
In use, the components that define the recirculating path are initially filled with oil. The pump 316 is switched on and the oil recirculates through the heater arrangement 318, the inlet manifold 310, the inlet pipes 306, the thermal chucks 190, the outlet pipes 308, the outlet manifold 31...
recirculating the working fluid in a closed loop. Description: BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to extraction of useful energy from hot fluids which may contain salts and other dissolved minerals. ...
