摘要： The invention is an improved tool for pulling a valve seat from a valve in a fluid end. The invention replaces the standard threaded nut and stem commonly used in such tools with a split nut comprising a plurality of removeably engageable split nut segments placed within a base and a stem configured to be used with the plurality of removeably engageable split nut segments. In the preferred embodiment, each split nut segment possesses a center-facing surface relative to the longitudinal axis of the invention comprising a set of horizontal v-grooves suitable to be disposed against complementary v-grooves of the stem. The base permits the plurality of split nut segments to be placed in an engaged position permitting the v-grooves of the split nut segments to removeably engage the v-grooves of the stem securely or to be placed in a disengaged position. The base containing the split nut segments is durable enough to be used in oil field work but lightweight enough to be used by individual or groups of workers safely.

摘要： Mass spectrometry apparatus 105 comprises a serial arrangement of an ion source 110, first time of flight means, a field free region 120, means to fragment the molecules, a second time of flight means and a large area detector 160 The second time of flight means includes an ion mirror 150, the ion mirror 150 being arranged to produce a reflecting substantially quadratic field. The first time of flight means is arranged to provide spatial focusing concomitant with time focusing of ions at or near the entrance to the ion mirror 150. The means provided to fragment the ions from the first time of flight means can be a collision cell 140 or in the field free region 220 or in the first time of flight means. The means to fragment the molecules has a potential which is different from the potential at the entrance to the ion mirror 150, and the detecting surface of the detector 160 is mounted in the time focal surface of the ion mirror 150.

摘要： The present invention provides a transpiration cooled rocket motor which operates at low combustion pressures, inherently provides stabilized combustion, and operates over a desired range of L-star. In a preferred embodiment the inventive transpiration cooled rocket motor includes: a housing; a porous injector sleeve; a propellant injector; and a nozzle. Preferably the injector sleeve lines the inside walls of the housing such that the inside volume of the sleeve forms the chamber for the motor. Liquid fuel passes inwardly through the pores of the injector sleeve and is injected from the sleeve into the chamber, thus cooling the walls of the rocket motor.
