Abstract: ABSTRACT OF THE DISCLOSURE        A shock absorbing system for protecting the legs of an offshore platform against excessive shock is disclosed.  The system has a vertical support column which is supported from its upper and lower ends.  A cylindrical protector is eccentri-cally positioned around the support column and provides a contact surface for vessels.  At least two rubber shock absorbing elements are designed to fit in the annular space formed between the column and the outer protector.  These shock absorbing members are positioned in axially spaced locations within the annular space.  These shock absorbing elements have their interior surfaces bonded to the interior vertical column.  The present system has eliminated many aspects of the prior art systems by taking into account the limited directions from which contact forces are applied.

Abstract: PROGRAMMED WELDING MACHINE WITH     WELD HEAD SPEED OVERRIDE Abstract Of The Disclosure A welding machine includes a programming device to move a welding head relative to horizontal main X and Y axes, and to rotate the head about a vertical C axis.  A sensor is connected to rotate with the welding head on a rotator.  A sine cosine resolver is mounted on the rotator so that its shaft is geared to the rotator gear.  Deviations from the programmed path which may occur in the weld groove are sensed by the sensor, which in turn causes the resolver output to drive a slide mechanism which defines deviation axes Xd and Yd and which causes the weld head to move from its programmed path to the desired corrected path, when needed.  The resolver includes a deviation correction control rotor winding and a second rotor winding, the latter selectively impressing signals on the Xd and/or Yd slide mechanism drive to cause the welding head to effectively change speed independent of the program or of the existence of any deviation.  In welding machines for simultaneously joining multiple pairs of workpieces, the speed control makes it possible to compensate for variations in gap widths.

Abstract: ABSTRACT          A printer control system for a belt printer has an arrangement for checking print hammer operating cir-cuits by comparing a real time actual parity of the circuits with a precalculated expected parity.  Prior to printing, a microprocessor calculates expected parity bytes for each subscan for storage in a storage device along with the print position fire data used for selecting the operating circuits to be activated in the related subscans.  An actual parity byte is generated on a real time basis by ODD/EVEN parity circuits associated with groups of operating circuits for comparison with a composite parity byte generated each subscan by the microprocessor.  The composite parity byte is generated by combining the expected parity bytes from the storage device for several successive subscans.  The composite parity byte is updated each subscan by a process of subtracting the initial ex-pected parity byte and adding a new subscan expected parity byte.  Comparison is made when all the acti-vating circuits are in stable condition.

Abstract: METHOD AND APPARATUS FOR SHAPING GLASS SHEETS BY ROLL FORMING                Abstract of the Disclosure This invention relates to shaping glass sheets by roll forming to either simple or complex curvatures about a single axis of bending or to compound curvatures comprising components of curvature about mutually perpendicular axes of bending by a controlled, repeatable program of roll forming without causing the glass sheets to stop their forward movement during their shaping.  The apparatus used to perform this process has a minimum of moving parts, thus minimizing maintenance problems and reducing down time for maintenance and repair.         In a variation of this invention, shaped solid members such as successive rotating shaping rolls of predetermined contour of a first configuration engage a heat-softened glass sheet to impart a preliminary curvature different from the final curvature to be imparted to the glass followed by imparting a final curvature significantly different from the first configuration by cooling the opposite glass sheet surfaces at sig-nificantly different cooling rates during the imposition of a temper thereto.

Abstract: METHOD AND APPARATUS FOR CONVERTING HAZARDOUS MATERIAL TO A RELATIVELY HARMLESS CONDITION     Abstract of the Disclosure A glass material is directed into an elongate enclosed conversion chamber, where it is either converted to or maintained in a molten state by heating through the Joule effect.  Waste material is directed onto the glass material at the inlet end of the conversion chamber, and sufficient oxygen is directed into the chamber to cause combustion of the waste material which is capable of being burned.  A portion of the ashes created by combustion fall on the glass material and become a part thereof.  The gaseous combustion products proceed horizontally through the elongate conversion chamber, and additional ash material suspended in the gaseous combustion products settles onto the glass material and  also becomes a part thereof.  The gaseous exhaust is directed through a plurality of ceramic fiber filter components which capture the small particulate material that remains suspended in the gaseous exhaust.          These filter components are periodically discharged into the molten glass material to become a part thereof and/or to become oxidized.  The glass material, with the other material added thereto, is periodically discharged to a cooling area to form a solidified product incorporating the ash product of the waste material.
