Abstract: Abstract of the Disclosure Apparatus for calibrating a fluid flow meter under test is disclosed as including a meter prover for directing a known volume of fluid through the meter including a chamber of known volume, a piston to be moved rectilinearly within the chamber and a motor for driving the piston, the chamber being coupled to the fluid flow meter under test to permit the flow of fluid between the fluid flow meter and the chamber. There is included a measuring device in the illustrative form of a rotary encoder coupled to the fluid flow meter to provide a first indication in the form of a first series of pulses indicative of the fluid flow as measured by the meter, and a second measuring device in the illustrative form of a high precision linear encoder coupled to the meter prover.  The linear encoder is responsive to the movement of the piston for providing a second indication in the form of a second series of pulses indicative of the fluid drawn by the meter prover through the fluid flow meter.  A control circuit in the form of a microprocessor is responsive to the movement of the piston to enable the accumulation of the outputs-of the-first and second measuring devices, e.g., counting the first and second series of pulses, and for terminating the accumula-tion, e.g., counting the first and second series of pulses, upon the accumulation of a given quantity or number of the first series of pulses, whereby the accumulated value or number of the second series of pulses provides a calibrated, precise manifestation of the fluid flow through the fluid flow meter as measured by the meter prover.

Abstract: ABSTRACT OF THE DISCLOSURE          A method is provided for eliminating internal voids in superplastically forming parts.  A blank of material which is capable of being formed superplastically is held opposite a forming surface of a die.  The blank is heated to the superplastic forming temperature and pressure is applied to both sides of the blank.  This pressure is suf-ficient to prevent the formation of voids.  The pressure on the side of the blank farthest from the die surface is then increased to superplas-tically form the material against the die surface.  In a second embodi-ment, the pressure is applied after the blank has been formed either by maintaining the forming pressure to compress the material between the forming pressure and the reaction of the die, or by applying a fluid pressure to both sides of the part, thereby removing voids by plastic deformation and diffusion.

Abstract: PROCESS FOR CHLORINATION OF POLY(VINYL CHLORIDE) WITH LIQUID CHLORINE, AND CHLORINATED POLY(VINYL CHLORIDE) COMPOSITION                 ABSTRACT OF THE DISCLOSURE A process is disclosed for the preparation of chlorinated poly(vinyl chloride), (hereinafter "CPVC" for brevity), in the form of free-flowing macrogranules which are derived from solid free-flowing macrogranules of poly(vinyl chloride), (hereinafter "PVC" for brevity), by causing from about 0.6 to about 3.0 parts by weight (wt) of liquid chlorine which are absorbed per unit wt of solid PVC macrogranules to react with the PVC, without shedding reacted material from the macrogranules. The macrogranules of PVC containing absorbed liquid chlorine held therewithin, are maintained in a wetted but free-flowing, apparently dry reaction mass (due to which the process is referred to as "the relatively dry chlorination" or "the low liquid chlorine" process), in a reaction zone maintained at a temperature in the range from about -50°C to about 50°C, and a pressure sufficient to maintain the chlorine in its liquid state. The reaction is carried out in the presence ofactinic radiation, but without swelling agents and the like. The process may be operated as a batch process, or a continuous process.          The CPVC formed by the process of this invention has improved processing and working characteristics. This CPVC is distinguishable from prior art CPVC compositions by its spectral fingerprint, and by the presence of 5-15 percent by weight (% by wt) of the CPVC as glassy macrogranules.          In another embodiment of the invention, a process is disclosed for simultaneously chlorinating (hence "co-chlorinating") a free-flowing mixture of solid PVC macrogranules and solid polyethylene ("PE") particles, without shedding reacted material from the macrogranules, to yield a mixed reaction product of separate macrogranules of CPVC and particles of chlorinated polyolefin, which mixture, in a preselected ratio of its components, may be directly used in an injection molding machine.           The reaction product formed by the co-chlorination process is visually distinguishable by the characteristic coating of individual CPVC macrogranules with particles of chlorinated polyethylene ("CPE" for brevity).
