Abstract: ABSTRACT                THERMOFORMING MACHINE      In the thermoforming of a sheet of thermoplastic material opposed successions of tooling steps each carry-ing an array of forming tools are driven in the same forward direction and in converging and then parallel paths.  A sheet of the heat softened thermoplastic material is fed between the forming tools adjacent the start of the convergence of the paths.  The relative approach and forward movement of the tooling steps is controlled to bring the opposed forming tools into contact with the sheet and progressively form the sheet by counterthrust between the opposed tools.  The sheet is drawn between the converging and parallel paths of the tooling steps and simultaneously is formed in accordance with the configuration of the forming tools. The formed sheet is maintained at a sufficiently high temperature, at least within the converging paths of the tooling steps, to permit any defects in the shape of the formed sheet that result  from the stepwise action of the successive tooling steps to be removed by dispersion of tensions in the sheet before it cools below its softening temperature.

Abstract: ABSTRACT      An improved method of defluorinating wet process phosphoric acid using silica-containing dust which is obtained as a waste product collected from the fumes of a submerged arc furnace process of making silicon metal alloys.          The silica-containing dust has a very small particle size, and contains at least about 60% by weight silica (Sio2), and has a very high surface/mass ratio which increases the effi-ciency of the defluorination reaction.      The defluorination reaction using this silica-contain-ing fume takes less time than required using prior methods employing diatomaceous earth as the silica source.  The pre-sence of silicon metal alloy particles in the dust are thought to have a catalytic effect on the defluorination reaction.

Abstract: ABSTRACT        An open air high voltage resistor for use with high voltage insulators, on which flashover tends to occur due to deposition of polluting external layers of dirt.  The resistor comprises a resistance element and is connected in series with the insulator so that any discharge current through the external layers produces a voltage drop through the resistance element. This voltage drop reduces the potential across the insulator preventing and retarding flashover.  The voltage drop across the resistance element is of at least about 5% and preferably of 10% to 30% of the full line to ground potential applied to the insulator at the critical leakage current over the insulator.
