摘要： A device and method for measuring slump of concrete in a hopper (20) feeding a concrete pump. A slump sensor generates a signal from either an ammeter (55) to measure current from a power source (51) feeding an electric motor (41) being configured to rotate an agitator shaft (31) or a pressure gauge configured to measure hydraulic pressure in a hydraulic drive hose passing between a hydraulic pump and a hydraulic motor configured to rotate the agitator shaft. A controlling computer (61) includes a memory in which an operating range may reside, the operating range being a range from a lower slump signal value corresponding to a lower limit of slump value to an upper slump signal value. The controlling computer (61) generates an alert signal when the slump sensor signal falls outside of the operating range. In one embodiment, the controlling computer stops the concrete pump (10) when the alert signal is detected.

摘要： Systems and methods for extracting hydrocarbon gas utilize a vacuum chamber (38, 64) with a mud chamber portion (92) that is expandable and contractible. Gas is extracted at vacuum pressures. A method of extracting hydrocarbon gas from hydrocarbon-bearing drilling mud comprises flowing hydrocarbon-bearing drilling mud into a degassing chamber (38, 64) of a degassing device (10, 60) and expanding a mud chamber portion (56, 92) of the degassing chamber to extract hydrocarbon gas from the hydrocarbon-bearing drilling mud.
