Abstract: A degasser for removing contaminating gases from an aqueous fluid including a motor having a depending drive shaft, a hollow gear box casing having a lubricant inlet port formed therein adjacent the top thereof, a reduction gear arrangement comprising a stationary ring gear fixed to said gear box casing below said inlet port; the ring gear arrangement including a ring gear having a lubricant outlet port formed therein in a groove between two of the teeth, a plurality of reduction gears operatively interconnected to said drive shaft, a lubricant reservoir adjacent the gear box, a lubricant inlet line interconnecting the lower portion of the lubricant reservoir with the gear box inlet port, and a lubricant outlet line interconnecting the top portion of said lubricant reservoir with the gear box outlet port, whereby each rotation of the reduction gear will force a pulse of lubricant from said gear box through said outlet port and said outlet line to said lubricant reservoir and, whereby, a corresponding pulse of

Abstract: A modified drilling mud degasser is used to simultaneously degas drilling mud delivered thereto from a mud tank and to supercharge a mud pump to which the degassed mud is delivered. This is accomplished through the provision of a drilling mud degasser and supercharger comprising power driven degassing means for removing gas from drilling mud delivered thereto and pump means for delivering degassed drilling mud therefrom to said mud pump at a predetermined pump supercharging pressure, and means for recirculating drilling mud from the drilling mud degasser and supercharger to the mud tank when the mud pump is not operating.

Abstract: A plural stage subatmospheric water deoxygenator of the type wherein oxygen-containing water charged through a water feedline is sprayed into a vacuum chamber for the removal of oxygen therefrom which also includes first stage vacuum chamber means including first stage scheduling means for simultaneously and continuously:1. Spraying charged pressured feedwater into the first stage vacuum chamber to initiate the removal of oxygen therefrom and2.
