Abstract: ABSTRACT OF THE DISCLOSURE:              The present invention is concerned with a crystal-line SiO2-modification, which is characterized by an X-ray diffraction diagram having certain diffraction lines, and with a process for the preparation of this crystalline SiO2-modifi-cation.  This process is achieved by heating a mixture of a reactive amorphous SiO2 in an aqueous solution of hexamethylene-diamine at a temperature of from 100° to 200°C for from 0.5 to 50 days, to effect crystallization of the SiO2 to the crystal-line SiO2-modification.  Sodium ions, phosphate ions and /or sulfate ions may be added for the crystallization.  With the novel process it is possible to prepare new , high-grade absorbents which have a definite pore size and are therefore particularly suitable for the selective separation of organic components from solvents.

Abstract: WELDING APPARATUS AND CONTROL SYSTEM THEREFOR                      Abstract A resistance-type welder employing a pulsed power supply and a pair of opposed electrodes between which a workpiece may be clamped under pressure, includes a microcomputer based control system for allowing pre-cise selection and control of welding sequences such as the duration during which the workpiece is clamped, the duration during which current is supplied to the electrodes and the duration during which the workpiece remains clamped between the electrodes after current flow is terminated.  A plurality of switchable input devices allows data corresponding to a plurality of process variables to be input to a randon access memory. A central processor enabled by a manually operable con-trol switch produces control signals for operating a control and firing circuit in accordance with programmed instructions and the data stored in the random access memory in order to control each step in a welding cycle for precise time periods.  A sensing circuit detects the level of power supply line voltage and inhibits operation of the central processor when the line vol-tage falls below a prescribed level.  Opto-electrical switches connected to the input devices isolate sensi-tive logic circuits from spurious input signals.  The control circuit also selectively operates a solenoid controlled, hydraulic cylinder for causing the elec-trodes to clamp the workpiece therebetween.
