Abstract: ABSTRACT OF THE DISCLOSURE   A cap for a radiator filler neck of the type having a peripherally extending upper lip and, downwardly from the lip, a radially inwardly and peripherally extending, upwardly facing pressure valve seat concentric with the axes defined by the neck and the cap.  The cap comprises an outer shell for engaging and closing the filler neck, a molded plastic retainer connected to the outer shell, and a molded plastic pressure valve member for engaging the valve seat.  The retainer has a peripherally and radially outwardly ex-tending flange and a downwardly extending shank, a sealing ring is carried by the flange for engaging and sealing against the upper lip, and the valve member is provided with an upwardly extending shank.  The shanks have inte-locking portions for connecting the valve member to the retainer and a spring is disposed about the shanks for yieldably urging the valve member against the valve seat as well as to maintain the interlocking portions in engagement.  The interlocking shank portions form a bayonet-type connecting arrangement in which one of the two shanks is moved axially into the other shank and then rotated and then moved axially in the opposite direction to complete the interlocking engagement.  The retainer is provided with a plura-lity of peripherally spaced apart, downwardly and radially outwardly extend-ing fingers which deflect resiliently inwardly to permit the retainer to be inserted into the shell and which then move radially outwardly to secure the retainer within the shell.

Abstract: CHIP DISCHARGE FOR               CONTINUOUS CHIP WRINGER              ABSTRACT OF THE DISCLOSURE    A centrifuge for continuously separating a lubricating liquid from lubrication-impregnated metal chips.  A motor having a drive shaft thereon is mounted so that the drive shaft is drivingly coupled to a substantially bell-shaped centrifugal drum having an outwardly widening conical portion.  The drum is formed with openings intermediate the top edge and bottom wall for discharge of the liquid there-through.  A metal chip and air inlet is provided adjacent the central portion of the outwardly opening drum.  A first collecting structure is provided for collecting the liquid emanating from the lubrication-impregnated chips and for discharging the liquid from the centrifuge.  A second annular collecting structure surrounds the peripheral edge of the drum radially outwardly spaced therefrom for collecting shavings discharged by centrifugal action from the drum.          An outlet duct is connected to the second collecting struc-ture and has a central axis extending tangential to the second collecting structure and away therefrom and defining a metal chip and air outlet.  A plurality of blades may be mounted on the drum adjacent the top edge and are movable therewith for effecting a movement of air into the second annular collecting structure from the air inlet and out through the outlet duct to effect an entrainment of the metal chips in the air movement for discharge out through the outlet duct.

Abstract: Abstract of the Disclosure A flow stabilizer is presented which equalizes the flow of fluid through the passageways of the channel diffuser used with a centrifugal type rotary compressor. Slots are formed in the sidewalls of the flow separating vanes in the diffuser.  The slots open into cavities within the vanes.  The multiplicity of cavities communicate by means of openings through the diffuser wall into a common closed manifold.  The fluid interconnection between the multiplicity of passageways in the diffuser and the encircling common manifold increases the operating range of the compressor since pressure surges in one or more passageways are quickly equalized.

Abstract: ABSTRACT OF THE DISCLOSURE       A circuit which provides a control signal to dynamically adjust the level of clipping for an audio signal is described. The criterion for allowable clipping employed by the circuit is whether the clipper induced distortion is noticeable; the clipper induced distortion may be audible, however, remain unnoticeable. A frequency weighted correlation is performed on the audio signal to evaluate the waveform and establish a unnoticeable level of clipping.

Abstract: REMOVAL OF MAGNESIUM AND ALUMINUM IMPURITIES       FROM WET PROCESS PHOSPHORIC ACID            ABSTRACT         Magnesium and aluminum impurities may be removed from wet process phosphoric acid by adding a fluoride ion donating compound, such as hydrofluoric acid, for example, to thereby provide about four fluoride ions for each aluminum ion.  Also, preferably, an aluminum ion donating compound, such as alum is added to the wet process acid to bring the aluminum ion to magnesium ion ratio up to about two to one to facilitate formation of crystalline compounds having the general stoichiometry MgAl2F8.          The treated filter grade acid is then further treated in a crystallizer to form large crystals which will readily precipitate so the purified liquid phase, low in magnesium and aluminum containing impurities, may be separated from the crystalline phase.

Abstract: Abstract of the Disclosure An auxiliary offshore rig and methods for using same wherein the auxiliary offshore rig is adapted to be used in conjunction with a primary offshore rig on an off-shore platform for relieving the primary offshore rig of well activities relating to tubular member or cable opera-tions.  The auxiliary offshore rig includes in one embodi-ment a truss member mounted for movement along the platform, a racking tower for receiving tubular members therein mounted on the truss member, and a working cage mounted within the racking tower and supported by the truss member adapted to be positioned in alignment with the well for providing a secondary working area beneath the rig floor which is mounted atop the racking tower.  In a second embodiment, the auxiliary offshore rig includes the truss member, the racking tower, and a drill tower which is mounted atop the racking tower for use in drilling opera-tions, the drill tower supporting a crown block assembly movably mounted upon a crown block support member mounted with the upper end of the drill tower, with the crown block assembly supporting a travelling block for vertically rais-ing and lowering tubular members with respect to the racking tower.  The methods for using the auxiliary offshore rig of the present invention includes in one instance the coordi-nated, simultaneous raising and lowering of tubular members into the well in order to reduce tripping time into the well.  Further, the methods of the present invention include a procedure whereby a tubular member supported by the offshore rig is connected with a service riser in such a fashion as to prevent compressive loading on the service riser with any live loads.
