Granted: 1987-04-28
Abstract: Application of: Gary D. Tyrell and Robert W. Hill For: Mine Roof Supporting Truss System Abstract Of The Disclosure A truss system is disclosed for use in supporting the roof of a  mine. The system comprises an assemblage of elements which per-mit more rapid and efficient installation than prior art truss sys-tems which have generally been installed as a secondary operation, after the standard, required bolting pattern is in place. The pre-sent system, on the other hand, may be installed concurrently with and in fact may become part of, the standard bolting system.  The system includes a pair of roof bolts installed in conventional fashion in drill holes extending at divergent angles into the mine roof on opposite sides of the mine opening. The bolts each extend through aligned openings in a bearing support plate and a separate angle block having a curved outel surface. The closed ends of a U-bolt, having a curvature corresponding to the surface of the angle block, extend around the two blocks with the open, threaded ends of the U-bolts facing one another. A pair of blocks having three parallel openings therethrough are placed on the two U-bolts, the open ends thereof extending through the outer openings, and secured with nuts. A rod threaded at both ends, or a plurality of such rods joined by a threaded coupler, extends through the center opening of the block, thereby joining the two U-bolts, and is se-cured by nuts on each end. The truss is tensioned to a desired degree by threaded advance of the nuts on the U-bolts and/or coup-ling rods. The angle blocks are disclosed in two embodiments, the first having a planar surface engaged by the bolt head or a flat washer, and the second having an inwardly curved cavity ty surrounding the opening through which the bolt passes and is engaged by a mating washer on the bolt head. The design of the second embodiment per-mits considerable variation in the relative angular orientations of the truss elements.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention concerns a unique method for producing an anti-lacerative glass assembly wherein a plastic composite anti-laceration sheet is to be bonded to a glass substrate sheet.  The plastic anti-laceration sheet includes an inner layer of polyvinyl butyral adapted to abut the glass substrate sheet, an intermediate layer of poly-ester, and an outer layer of abrasion resistant material.  A glass cover sheet having substantially the same curvature as the glass substrate sheet is utilized to press the anti-laceration sheet into bonding engagement with the glass sub-strate sheet.  In accordance with the present invention, the bonding operation is accomplished by heating the laminated glass assembly a predetermined temperature in the range of 285° F to 305° F.  It has been found that such a temperature must be sufficiently high to cause the intermediate layer of polyester to bond to the inner layer of polyvinyl butyral, and to cause the inner layer of polyvinyl butyral to bond to the glass substrate sheet, and must be sufficiently low to prevent crazing of the abrasion resistant coating.  The present invention also concerns the use of a unique vacuum ring construction which is mounted about the periphery of the laminated assembly and is utilized to de-air the assembly.  The vacuum ring is provided with a check valve to maintain the vacuum within the ring during periods wherein it is disconnected from a vacuum source.  Further, the method of the present invention includes the step of re-moving a selected portion or portions of the anti-laceration sheet after it has been bonded to the glass substrate sheet to provide an exposed glass surface for use in mounting the glass assembly into an associated frame.

Abstract: INPUT PROTECTION ARRANGEMENT FOR VLSI INTEGRATED CIRCUIT DEVICES            Abstract of the Disclosure An input protection arrangement for diverting current from high voltages due to, for example electrostatic discharges into a bonding pad of an integrated circuit chip.  The chip has a bonding pad connected to a conducting path and to a source or drain region of an insulated gate field effect transistor, the other region being connected to a power bus on the chip. the conducting path runs between the source and drain regions and operates as the gate terminal of the transistor.  The conducting path is insulated from the surface of the chip by a field oxide insulating layer of a substantially uniform thickness to prevent rupture of the oxide between the gate and the source and drain regions in the event of high-voltages.  The source and drain regions include regions of conventional doping levels having depths corresponding to the depths of the other corresponding regions on the chip, surrounded by large wells of lower doping levels.  The input pad is separated from the chip substrate by an insulating oxide layer and by a doped well of the same conductivity type as the source and drain regions of the transistor to reduce the input capacitance and prevent punch through from the pad to the substrate.
