Abstract: PROCESS FOR TREATING MOLYBDENITE    CONCENTRATES TO PRODUCE A  LUBRICANT GRADE PRODUCT     Abstract of the Disclosure A simple, efficient and economical process for purify-ing molybdenum disulfide concentrate, by contacting and digesting the molybdenum disulfide feed material with an aqueous acid solution containing a controlled combination of hydrofluoric acid and sulfuric acid in a manner to convert substantially all of the contaminating silica bearing minerals therein to aqueous soluble fluoride and sulfate compounds and any contaminating lead sulfide compounds to lead sulfate compounds, and thereafter washing, neutralizing and drying the purified molybdenum disulfide powder product. In accordance with a preferred practice, when the molybdenum disulfide feed material contains in excess of about 0.1% iron as an indication of pyrite concentration, the concentrate is calcined at an elevated temperature in a nonoxidizing atmosphere prior to the digestion step to effect a conversion of the pyrites to synthetic pyrrhotites, which are softer and less abrasive and are more acid soluble. The product thus derived is eminently suitable for use in the formulation of lubricants and as an intermediate in the synthesis of high purity molybdenum compounds.

Abstract: ABSTRACT OF THE DISCLOSURE         A coupling flex-plate member comprising a circular metallic member having a centrally-disposed annular groove provided therein, is fixedly secured to the confronting ends of adjacent inner high-voltage tubular conductors of a gas-insulated transmission line to permit a limited, but sufficient flexibility, of the inner conductor sections, or conductor buses.  A low-strength high-conductivity material is used for the coupling flex-plate member, and permits an axial bending in a spring-like fashion until material yielding occurs.          Inaccuracies during fabrication and assembly of the component parts are accommodated by the use of such a coupling flex-plate member without damaging adjacent components, especially spacing insulators, which are, of course, brittle and subject to fracture.

Abstract: TAG ATTACHING APPARATUS          Abstract of the Disclosure There is disclosed apparatus for attaching tags using fasteners of a type having a bar section and a button section joined by a filament section. The apparatus includes a body with a pair of body sections keyed together in part by a needle having an elongated bore and a side opening.  A push rod is engageable with the bar section to push the bar section through the needle bore while its filament section extends through the slot.  Opposed operating levers are pivotally mounted on opposite sides of the body.  Each lever carries a cam.  A first carrier is mounted by the body and a second carrier is mounted by the first carrier.  The push rod is connected to the second carrier.  The first carrier has a pair of carrier members and each carrier member carries a post which rotatably mounts a gear.  The carrier members are collected by a pin which rotatably mounts a pair of rollers.  Each cam cooperates with a respective roller.  A rack is secured to each body section and the second carrier has a pair of racks.  Each gear meshes with a respective body section rack and a respective second carrier rack.  A pawl is coupled to the first carrier through a lost-motion connection so that only part of the movement of the first carrier is imparted to the pawl.  Action of the operating levers causes the cams to drive the rollers to in turn drive the first carrier.  Movement of the first carrier causes the racks and gears to drive the push rod forward through a distance twice as great as movement of the first carrier.  Near the end of the forward movement of the push rod, the pawl is moved to a ready position.  A spring acting on the first carrier returns the carriers, the levers and the push rod to their respective initial positions and moves the pawl away from its ready position to drive a toothed wheel of a fastener advancing means to bring a bar section of the next successive fastener into alignment with the needle bore.  The pawl is cooperable with a cam disposed at a preselected position so that the toothed wheel with which the pawl cooperates can be driven through a preselected angle.
