Abstract: ULTRAHIGH PURIIY SILANE AND                SILICON PRODUCTION              Abstract of the Disclosure Tri-and dichlorosilanes formed by the reaction of metallurgical silicon, hydrogen and silicon tetra-chloride as subjected to disproportionation in the presence of an ion exchange resin to form high purity silane, with unreacted and by-product materials being recycled.  Said chlorosilanes are passed through distilla-tion zones and disproportionation reaction zones to pro-gressively replace chlorine molecules with hydrogen mole-cules so that product silane is eventually recovered from the process and silicon tetrachloride is recycled for further hydrogenation.  The process flow employed ensures that all of the process fluid passes through at least one disproportionation reaction zone for contact with ion exchange resin therein.  This ensures that boron impur-ities present in said fluid are removed to desirably low levels such that ultrahigh purity silane product can be produced,  This product can be decomposed in a fluid bed or free space reactor to form ultrahigh purity silicon and by-product hydrogen that can be recycled.  The result-ing ultrahigh purity silicon can be employed for solar cell and for electronic applications S P E C I F I C A T I O N

Abstract: ABSTRACT OF THE DISCLOSURE      This device for inductively heating and fusing thermo-plastics includes an alternating current passing through a tank circuit, the inductor member of the tank circuit being wrapped around a curved pole piece of a ferromagnetic material. The magnetic flux arising within the inductor coil member flows to the ends of the pole piece and into a screen placed between the materials to be joined.  The flux induces a current in the screen, and heat is generated to melt the thermoplastics together.  Because only 30-150 watts of power are passed through the tank circuit, a wire which will remain cool under operational wattage may be selected, making air or fluid cooling unnecessary.

Abstract: ABSTRACT OF THE DISCLOSURE A pressure ratio measuring system is disclosed.  The system includes two quartz capacitive pressure transducers (16, 22).  Each capsule contains a pressure sensitive capacitor (Csa, Csf) which is fed by an alternating excitation signal.  Capacitance (Csa) is fed by excitation signal (Vr) and Capacitance (Csf) is fed out of phase by feedback excitation signal (-Vr f(N)).  The outputs of the capaci-tance are combined in a summing junction (36) whose output is an error signal (le) proportional to the pressure ratio.  A feedback loop (26) is closed through a register (30) and a multiplying digital to analog converter (32) to generate the feedback signal  (-Vr f(N)).  The feedback loop (26) integrates the error signal (le) by incremental changing the feedback signal (-Vr f(N)) with digital number (N) in a direction to null the loop.  When the loop is nulled the digital number (N) is a representation of the ratio (Pa/Pb) of the pressure (Pa) sensed by capaci-tance (Csf).     (Figure 2)
