Abstract: A METHOD FOR DETERMINING AND DISPLAYING THE SHEAR-VELOCITY REFLECTIVITIES OF A GEOLOGIC FORMATION            Abstract In a method for determining and displaying the shear-velocity reflectivities of a geologic formation, a compression-wave common-depth-point seismic-data-gathering technique is utilized to produce both normal incidence compressional-velocity reflectivity sections and shear-velocity reflectivity sections for reflection points in the formation.  The common-depth-point information is gathered for a plurality of incidence angles, (theta), of less than 20-30° such that assumptions concerning various elastic parameters, density, compressional-wave-velocity and shear-wave-velocity can be made which allow the application of linear fitting techniques to the gathered data.  Estimates are then made of the coefficients (Rpp,0 and Rpp,1) of a linear function fitted to the amplitudes vs. sin2 (theta) measured for each point of reflection. The sum of these coefficients corresponds to the shear-velocity reflectivity of the reflection point and may be presented with similar data for other points in appropriate shear-reflectivity sections.

Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed are a blow molding method and machine for forming from a continous tube of substantially unoriented normally highly crystalline thermoplastic material at its orientation temperature a chain of hollow, shaped article bodies in which the material is biaxially oriented.  The machine comprises a tube and chain transporter, a tube brake, and at least one stationary blow mold.  The transporter functions to pull the tube from a first point to a second point, and to push beyond the second point that portion of the chain formed between the two points.  The tube brake functions to brake the travel of the tube past the first point during at least part of the time it is being pulled, whereby the part of the tube between said points is longitudinally stretched.  The stationary blow mold has at least two mold pieces that close on the stretched part of the tube, and open after formation of the hollow body in the cavity defined by the closed mold pieces.  The mold also comprises means for inflating the portion of the stretched part of the tube within the mold cavity, whereby one of said bodies is formed therein, and the material thereof becomes biaxially oriented.

Abstract: POSITIVE DISPLACEMENT INJECTOR    ABSTRACT OF THE DISCLOSURE          A positive displacement injector for automatic cen-tralized lubrication systems is constructed to include a two-piece disk-seal valve assembly that acts as a check valve and also provides seals at oppositely facing sur-faces.  The assembly consists of a stiff disk sandwiched between upstream and downstream disks of a resilient seal member.  Notches in the periphery of the stiff disk are normally blocked by the downstream disk to prevent upstream fluid flow through these notches, yet the periphery of the downstream disk is deflectable to permit downstream fluid flow through the notches when there is relatively high fluid pressure at the inlet port.  The assembly is bodily movable so that with low fluid pressure at the inlet port this port is blocked by the upstream disk, and with high fluid pressure at the inlet port the downsteam disk blocks axial input to an outlet passage.

The PUREX waste is concentrated to about 30 to about 40 percent solids and a colloid of  such de-alcoholated alkoxides of silicon, boron, and aluminum are added to the PUREX waste as are necessary to produce a mixture containing about 0.001 to about 1 percent aluminum hydroxide,  about 5 to about 15 percent  silica,  and about  1  to  about 3 percent boric oxide.  The resulting mixture is heated to about 400 to about 700°C which produces a cinder.  The cinder will be transported to a vitrification center where  it  can be disintegrated in ammonium hydroxide and the nuclear waste can be permanently encapsulated in glass.
