Abstract: A rotary abutment type hydraulic motor is disclosed comprising a housing having a rotor chamber and a pair of abutment valve chambers intersecting the rotor chamber. A rotor having at least three lobes is disposed in the rotor chamber, and a two lobed stator is provided in each of the abutment valve chambers. The abutment valve axes are circumferentially spaced apart one-half the angular spacing between adjacent rotor lobes. A unique sealing arrangement is provided between the rotor lobes and rotor chamber wherein sealing pins carried by the rotor lobes are hydraulically displaced radially outwardly to sealingly engage the inner surface of the rotor chamber during motor operation. A unique abutment valve lobe rotor hub sealing arrangement is also provided which is defined by a metal plate extending between adjacent rotor lobes and hydraulically displaceable metal pins disposed beneath the plate in recesses in the rotor hub. Hydraulic fluid under pressure biases the pins outwardly against the plate to bias the plate into sealing engagement with the abutment valve lobes during interengagement therebetween. Opposite ends of the abutment valve shafts are provided with a floating bearing and seal arrangement which is responsive to hydraulic fluid under pressure to seal the shaft ends against leakage of hydraulic fluid thereacross.

Abstract: Method and apparatus for detecting, distinguishing and indicating low-level activity of radioactive gases, such as tritium and/or krypton-85, in a selected gas, even in the presence of electronegative gases. The apparatus consists of a detection chamber of a type which is energy selective through inclusion of plural ionization collector circuits providing two separate detector outputs. The two detector outputs are applied then to parallel signal processing channels which serve to separate detected energy through pulse amplitude discrimination and/or coincidence selection to determine absolute quantities of radioactive events for selected contaminants in the gas sample.
