Abstract: METHOD AND APPARATUS FOR THE INTERFEROMETRIC   WAVELENGTH MEASUREMENT OF FREQUENCY TUNABLE                      C.W. LASERS               Abstract of the Disclosure The invention relates to a method and an apparatus for measuring the wavelength of an object beam of electromagnetic radiation generated from a first source means by comparing with a reference beam of known wavelength generated from a second source means, A fringe-countiny Michelson-type interferometer is used, which has a stationary arm and a variable arm and in-cludes planar beam splitting means for splitting each of the reference and object beams into first and second beam portions, planar beam mixing means for recombining the respective first and second beam portions of the reference and object beams, planar reflection means arranged in the stationary arm for reflecting the respective first beam portion of the reference and object beams to the beam mixing means and movable retroreflection means having an optical center and arranged in the variable arm for reflecting the res-pective second beam portion of the reference and object beams to the beam mixing means.  Prior to moving the retroreflection means, the reference and object beams are aligned to provide a flat interference pattern for each beam sent to the beam splitting means at only one incident direction, by causing the reference and object beams to travel along respective optical paths lying in respective parallel planes which normally intersect the planes of the beam splitting means, the beam mixing means and the reflection means and pass through the optical center of the retroreflection means, the respective second beam portion of the reference and object beams being directed to and reflected by the retroreflection means off center thereof, reflecting with the reflection means the respective first beam portion of the reference and object beams at an angle of reflection .alpha., and disposing the beam mixing means relative to the beam splitting means such that the plane of the beam mixing means is angularly inclined with respect to the plane of the beam splitting means by an angle equal to .alpha. and that the beam mixing means is oriented to receive the respective reflected first and second beam portions of the reference and object beams symmetrically with respect to the plane thereof.          Parallelism of the second beam portions with one another in the variable arm of the interferometer is auto-matically provided as a result of the alignment of the reference and object beams to a flat interference pattern, without optical feedback of the beams to their respective source means and parasitic diffraction effects by the retroreflection means.

Abstract: ABSTRACT OF THE DISCLOSURE:     A method and apparatus for pumping a well using a jet pump.  The method includes the steps of pumping a power fluid downwardly in a first flow path in a well, correcting the power fluid across into a second flow path in the well leading back to the surface, pumping the power fluid upwardly through a jet pump in the second flow path, introducing pro-duced fluids into the jet pump from the second flow path below the jet pump, and mixing the produced fluids with power fluid in the jet pump and pumping the mixture of fluids up-wardly to the surface through the second flow path along a substantially straight line from the zone of mixing in the jet pump to the surface along the second flow path.  The apparatus includes a jet pump having a housing provided with a central bore closed at a lower end and having a transverse bore opening into the lower end of the central bore for ad-mission of power fluid, a nozzle body and nozzle in the central bore above the transverse bore, a throat and diffuser in the housing bore above the nozzle, flow passages into the housing from the lower end of the housing around and separate from the transverse bore and an annular entry passage from the bypass flow passages into the housing bore between the nozzle and the throat for admission of produced fluids into the housing bore downstream from the nozzle in response to a low pressure in the throat produced by the nozzle.  The jet pump is connected with a locking mandrel for releasably locking the pump at a landing nipple profile in a producing tubing string.  The nozzle body, jet, throat, and diffuser of the jet pump are arranged in tandem along a straight line axis so that producing fluids are drawn into the jet pump, mixed with the power fluid and discharged from the jet pump along a substantially straight line avoiding direction changes and thus eliminating erosion due to impinge-ment of abrasive solid particles in the produced fluids on internal production equipment surfaces.  The method and jet pump apparatus are used in either a dual tubing string well system or a tubing-casing annulus arrangement.  Either pump-down or wireline equipment and techniques are used for in-stallation and removal of the jet pump apparatus.

Abstract: Title Case Hardening Method For Steel Parts Abstract of the Disclosure A method of case hardening surfaces of steel parts insures the presence of a relatively high percentage of untempered martensite within a case hardened depth of at least ten thousandths of an inch.  The untempered martensite provides for a Rockwell C surface hardness in the range of 59 to 68, and promotes greater resistance to abrasion and deformation.  The method also creates compressive stresses in the surface case hardened depth, and thus measurably enhances the fatigue life of the latter surface as a contact bearing member.  The method includes the completion of all conventional metal removal operations on the part including finish machining steps prior to heat treatment thereof.  In one preferred form, the method includes the steps of (1) completing all machining operations on the part, (2) carburizing the part to achieve a high surface carbon concentration, (3) direct quenching the part in oil by means resulting in retention of 10 to 30 percent austenite in the case hardened depth, (4) time tempering the part and (5) work hardening the part to transform a substantial portion of the retained austenite into untempered martensite, resulting in a case depth having a composition including at least 5 to 20 percent untempered martensite.

Abstract: ABSTRACT      An improved magnetic gas gate is adapted to operatively interconnect two adjacent chambers, in the first chamber of which process gases are in-troduced for depositing a first layer upon a mag-netic substrate and in the second chamber of which process gases are introduced for depositing a second layer atop the first layer.  Since it is important to prevent the second chamber gases from contaminating the first chamber gases, a constant pressure differential established between the chambers is employed to provide a substantially unidirectional flow of gases to the first chamber from the second chamber.  Magnetic gas gates have been used in the prior art to reduce the size of gas gate passageways by creating a magnetic field which urges the unlayered surface of the substrate toward a wall of the passageway.  Although the size of the passageway opening is thereby reduced with a corresponding reduction in back diffusion of gases to the second chamber, the passageway is simultaneously divided into a relatively large flow channel and a relatively narrow flow channel.         The present invention reduces the back diffusion of gases through the relatively narrow flow chan-nel by forming a plurality of elongated grooves in the passageway wall toward which the unlayered surface of the substrate is urged.  The grooves are substantially coextensive with the length of the passageway so as to operatively interconnect the adjacent chambers.  The flow channels thus established are adapted to accommodate a suf-ficient flow of inert sweep gases to further re-duce the back diffusion of process gases through the narrow flow channel.
