Abstract: A jet pump system is shown that utilizes waste heat to provide heating and/or cooling. Waste heat diverted through a boiler causes a refrigerant to evaporate and expand for supersonic discharge through a nozzle thereby creating a vacuum in an evaporator coil. The vacuum draws the refrigerant in a gaseous state into a condensing section of a jet pump along with refrigerant from a reservoir in a subcooled liquid form. This causes condensation of the gas in a condensation section of the jet pump, while moving at constant velocity. The change in momentum of the fluid overcomes the system high side pressure. Some of the condensate is cooled by a subcooler. Refrigerant in a subcooled liquid state from the subcooler is fed back into the evaporator and the condensing section with an adequate supply being insured by the reservoir. The motive portion of the condensate is returned to the boiler sans subcooling. By proper valving start-up is insured, as well as the ability to switch from heating to cooling.

The flex member consists of four flat arms, arranged to form two Vs with their interior angles facing one another, and a connecting piece connected to and extending between the vertices of the two Vs.

Abstract: A float with an iron rod movable within a double coil AC coupling network measuring backed up liquid level as the measure of open channel, ditch or stream liquid flow through a weir or parshall flume. The AC output of the liquid measuring double coil is rectified and converted to a direct current signal passed to a voltage-to-frequency converter having a frequency output sensed and processed by a microprocessor. In a memory of the microprocessor there is a flow rate for each frequency that is calculated according to the number of gallons that will flow in a unit time. Thus, it is not necessary to linearize the coil and the same kind of coil can be used for any flow, with only a memory table in the microprocessor memory being changed for linear correction. This flow rate may be added for totalizing and/or put out to a digital-to-analog converter for recording and, if desired, controlling.
