Abstract: TIGHTENING SYSTEM                 Jerry A. Sigmund ABSTRACT OF THE DISCLOSURE        A tightening and control system is disclosed for auto-matically tightening a fastener to a predetermined tightened condition in a workpiece, where the fastener is of the type which exhibits more than one installation region on a graph of two tightening characteristics during a complete tightening cycle.  Typical of such fasteners are thread tapping fasteners, such as thread-cutting or thread forming types, which first generate a mating thread in a workpiece material and there-after are tightened in the workpiece to a predetermined load condition.  Such fasteners typically exhibit a curve of two related input tightening characteristics, such as torque and rotation, or torque and time, for example, having a thread forming region characterized by a generally linear portion of the curve followed by a marked drop off in the slope, an intermediate region and a tightening region having a somewhat similar shape to the thread forming region.  The intermediate region may assume any one of several characteristic shapes.          Apparatus describing several embodiments is generally disclos-ed for determining the gradient of the torque-rotation curve through which the assembly including the thread tapping fastener is tightened, determining when a first condition indicative of having formed the thread has occurred, and there-after determining when the tightening region has been reached and utilizing the gradient information of the curve to determine when tightening should be discontinued at the predetermined tightened condition.  Typically, this predetermined tightened condition may be the yield point of the assembly.       In another embodiment of the invention, the gradient is used to determine the occurrence of the first condition following the thread forming region of the curve.  The instant-aneous torque value at this first condition is obtained and Stored, and tightening is discontinued when the instantaneous torque bears some predetermined relationship to the instant-aneous torque value at the first condition.

Abstract: ABSTRACT OF THE DISCLOSURE         A helicopter main rotor blade comprised of roll formed structure is provided.  A C-shaped nose spar, a closure channel, a protective strip and a nose block are all roll formed. The nose spar extends the length of the leading edge of the helicopter blade, and is open to the rear between upper and lower trailing edge skins.  The nose spar is flared adjacent the root whereby the trailing edges of the nose spar diverge from the leading edge as the nose spar extends toward the blade root.  The closure channel is attached to the inside surfaces of the upper and lower trailing edges of the nose spar.  The closure channel diverges from the leading edge as it extends toward said root.  The protective strip is secured to a lead portion of the nose spar to capture a nose block against the lead edge of the nose spar.  A trailing blade skin is held against upper and lower outer trailing surfaces of the nose  spar by means of body doublers extending from the trailing edges of the protective strip and overlaying the trailing edge  or the spar over the closure channel.  Flats exists because the airfoil element comprising the upper and lower trailing edges of the nose spar and the closure channel diverge from normal positions in the airfoil.  The flat diverges with the flare of the spar and is faired into blade contour.  Where the flat extends to a section of the airfoil thinner than the flat, it is faired into the airfoil with a bulge aft.

Abstract: APPARATUS FOR MIXING GAS AND LIQUID AT A DOWNHOLE LOCATION            Abstract of the Disclosure Apparatus for mixing a gas, e.g., oxygen, and a liquid, e.g., leach solution, at a downhole location in a well for treating a formation, e.g., in situ leaching of uranium.  The apparatus comprises a mixing means which is adapted to be affixed to the lower end of the gas supply conduit and is lowered into and raised out of the well by means of the conduit.  The mixing means is comprised of a solid, noncorrosive plate having a central opening into which the gas conduit is secured.  The plate has a plural-ity of additional openings surrounding the central opening and has a gasket thereon to form a seal between the plate and the well bore.  Liquid is flowed down the well and passes through the additional openings in the plate.  At the same time, gas is supplied through the conduit and flows through the central opening in the plate.  Due to the increased velocity of the liquid caused by the liquid as it flows through the additional openings in the plate, the gas is trapped to form a gas pocket below the plate.  Liquid flows through the gas pocket and thereby becomes saturated with the gas.

Abstract: PROCESS FOR REMOVING UNREACTED MONOMERS FROM POLYMERIZATION SLURRIES      ABSTRACT OF THE DISCLOSURE The method of recovering unreacted mono-olefinic monomers from an acrylonitrile polymerization slurry contain-ing 30 to 50 weight percent of polymer solids and 70 to 50 weight percent of unreacted monomers wherein the slurry is first diluted with a solvent for the polymer and then fed in series through first and second treatment zones, with each of the treatment zones having a first stage for mixing the slurry with a solvent in vapor form to vaporize some of the unreacted monomers from the slurry and form a polymer solu-tion and a second stage for separating monomer vapors from the liquid polymer solution.  Fresh solvent, in vapor form and at an elevated temperature is supplied to the mixing stage of the second treatment zone and the vaporized solvent and unreacted monomers from the separation stage of the sec-ond treatment zone are fed to the mixing stage of the first treatment zone.  The preferred ratio of solvent to slurry being fed to the mixing stages is 0.8 to 1.2.  The slurry leaving the separation stage of the second treatment zone has a very low content of unreacted monomers.

Abstract: OPTICAL APPARATUS FOR SELECTIVELY PRODUCING           RIPPLED MESSAGE IMAGES IN AREAS OF SPECULAR           SURFACED PHOTOPLASTIC FILM AND ERASING SUCH                IMAGES FROM SUCH AREAS FOR REUSE         ABSTRACT    Optical camera and image processing apparatus for selectively producing rippled message images in frame areas of specular sur-faced photoplastic film by image patterned electrostatic charge and heat deformation.  Image bearing light beam is projected through an objective lens unit and focused upon a transverse photo-plastic film supporting means.  Such supporting means includes a lateral platen located back of a section of said film which margins a specular surface area of such a film frame.  Means intervening the objective lens unit and the position of a film section when supported upon the platen provides an optical aperture.  This film supporting platen has an opening opposite the optical aperture whereby the back of the film opposite its specular surface area is accessible.  A heatable metallic block is movably mounted so that it can be moved forward into the platen opening for contact of the accessible area of the back of the film to effect conduction heat softening of this film area that is located between the optical aperture and the platen opening for producing such a rippled frame area.  Grounding means is associated with the film section when supported upon this apertured platen, and electrostatic charging means imposes upon the platen a relatively large electrostatic charge differential which causes the platen supported film area to be snugged to the platen.     Between the film supporting means and the objective lens unit is provided means for producing and directing forward to the platen supported area of the film an electrostatic charge.  It is preferable to provide between the objective lens unit and such electrostatic charging means a shutter mechanism which may be open-ed to pass the image supporting beam onward to the supported film area and to terminate such beam passing with a discontinuance of the application of the electrostatic charging action.    Various forms of optical apparatus for using specular surfaced photoplastic film to bear or bearing rippled message images in frame areas thereof may be provided which are to handle such film in a form having a conductive substrate below its upper heat-softenable and image rippleable emulsion layer serving as an electrostatic grounding means, such apparatus will include platen means having a lateral film supporting surface with an area of the latter contacting the lower side of an area of such film, and means imposing a relatively large electrostatic charge differential upon said platen to cause the area of said film that is in contact with said piston  to be snugged to the latter by electrostatic charge adherence.
