    摘要: Apparatus and systems are disclosed for improved set-up of multi-ingredient compounders. An improved apparatus includes a manifold and a plurality of valve members disposed for movement relative to different corresponding ones of a plurality of inlet ports of the manifold. The valve members are moveable to open and close a corresponding fluid passageway between the corresponding inlet port and an internal passageway of the manifold. A plurality of caps are locatable on different corresponding ones of the inlet ports, with each of the caps being engageable with the corresponding valve member for co-movement from a locked position at which the cap is restricted from removal to an unlocked position at which the cap is removable, e.g. by manual, axial retraction of the cap. An improved system includes a compounder controller operable to control valve actuators of the compounder so as to sequentially move the valve members and corresponding caps from locked to unlocked positions in a predetermined sequence, thereby reducing the potential for undesired cross-connections.

    摘要: There is provided a gas mixer arrangement comprising a first gas source for supplying a first gas; a second gas source for supplying a second gas different from said first gas; first and second flow regulation devices for regulating the respective flow of the first gas and second gases from the first and second gas sources; a mixer; and an outlet. The mixer is located downstream of the first and second flow regulation devices and arranged, in use, to mix the first and second gases to provide a mixed gas to the outlet. The gas mixer arrangement further comprises a meter comprising a first sensor assembly operable to determine the average molecular weight of the mixed gas and including a high-frequency planar piezoelectric crystal oscillator in contact with the mixed gas, a second sensor assembly operable to determine the pressure of the gas downstream of one of the first or second flow regulation devices, and a controller operable, in response to the average molecular weight of the mixed gas and said gas pressure, to control automatically said first and second flow regulation devices to control the relative proportion of the first and second gases in said mixed gas and the pressure or mass flow rate of the mixed gas from the outlet.

    摘要: A system and method that automatically transfer liquid manure from an intermediate holding receptacle to a lagoon involves a common pump for both agitating the liquid manure in and pumping the liquid manure from the receptacle. A pump motor, first valve, second valve and directable agitation nozzle of the pump are controlled by an electronic controller. The electronic controller switches on the pump motor, ensures that the first valve is closed and ensures that the second valve is open when the receptacle is full, directs the nozzle to at least two different locations in the receptacle to permit liquid manure to be redirected to the at least two different locations to agitate the liquid manure for a predetermined period of time, and opens the first valve after the predetermined period of time to permit pumping of the liquid manure from the receptacle to the lagoon. The system and method reduce equipment cost, equipment maintenance and the amount of operator time required to perform liquid manure transfer, while providing better agitation and more complete emptying of the receptacle in a shorter period of time.
