Abstract: ABSTRACT OF THE DISCLOSURE         Unauthorized removal of the cap from a standpipe, such as a fire line standpipe, is prevented through use of a bent metal bar and a nipple formed at the center of the standpipe cap.  The bar has an opening to accept the nipple extending from the standpipe cap, and a slot to receive a metal pin which prevents movement of the standpipe cap, rotation of the cap being prevented by additional means formed on the cap and bar.          The bar can be so formed as to also prevent unauthorized removal of the handwheel of the valve which permits liquid flow through the standpipe opening.

Abstract: Abstract of the Disclosure Copper sulfide ores are processed by a unique series of steps to produce blister copper, while attaining long sought advantages an initial smelting step is carried out in any desired manner, e.g. according to conventional practice, to produce a molten, copper sulfide matte or white metal. This matte or white metal is then solidified and subjected to a size-reduction step to produce solid particles capable of being injected into a converting vessel instream of oxygen, either pure oxygen or air significantly enriched with oxygen. With the matte of white metal injected in this manner, the converting reaction may be carried out on an autogenous basis, with continuous evolution of substantially undiluted S02 gas capable of being liquified for use in the production of elemental sulfur or sulfuric acid or for disposal so as to avoid atmospheric contamination. The usual fugitive gas emissions resulting from the handling and transporting of molten matte in conventional ways are almost completely avoided, and continuous optimized operation of the converting vessel is achieved independently of operation of the smelting step, making it possible to eliminate the often-resorted-to close coupling of smelting and converting furnaces and affording unusual freedom in plant layout.

Abstract: ABSTRACT          An integral wood veneer strip (10) having first, second (62) and third (64) mutually generally perpendicular portions is produced simply and easily.  A number of similarly shaped thin strips of wood (11), with adhesive (12) between them, are placed together to form a linear laminate.  Before curing of the adhesive, the laminate is placed in contact with a particularly contoured female die surface (25), with a flexible band (13) over the laminate.  A male die surface provides a pressing force at a central portion of the band to press the laminate into close conformance with the female die surface, and the ends of the band are attached up to rollers (17, 18).  The rollers are rotated to tighten the ends of the band, also bringing the ends of the laminate into tight contact with the female die surface.  The adhesive is cured while the laminate is in the bent position (the curing may be facilitated by using microwaves from source 57), and then the laminate is released after curing, and may be utilized as decorative molding for furniture (66).

Abstract: Abstract of the Disclosure A UO steel pipe welding method for welding an inner seam of a UO steel pipe along an inner groove by welding electrodes held by a boom which is supported by a tracing roller moving along the inner groove of the steel pipe.  According to the invention, at least one metal plate is urged against at least one end of the steel pipe after tack welding the seam on an opposite side of the inner groove of the steel pipe to be welded, and lateral angular deformations of the end of the steel pipe on both sides of the seam due to a load of the boom when the tracing roller leaves the end of the steel pipe onto the metal plate, thereby preventing hot cracking at the end of the pipe.          According to the invention, moreover, portions of the steel pipe on both sides of a distal end of a weld bead at the end of the pipe are heated to cause expansion displacements of the heated portions directing toward a center of the weld bead or high temperature portions of the steel pipe after a heat source for the seam welding has passed therethrough are cooled, thereby reducing tearing forces acting upon the weld bead to prevent the hot cracking at the end of the pipe more effectively.

Abstract: FUEL FLOW MONITOR FOR AN ELECTRONIC FUEL INJECTION CIRCUIT     ABSTRACT OF THE DISCLOSURE     The invention contemplates fuel flow monitoring apparatus used in conjunction with an electronic fuel injection circuit for an internal-combustion engine.  Electronic fuel injection circuits have vastly improved engine performance and efficiency, but their effectiveness has been hampered by the fact that fuel flow has in the past been monitored by mechanical fuel flow sending units.  The instant invention eliminates the need for a mechanical fuel flow sending unit and replaces it with electronic circuitry which provides both an indication of fuel flow rate and total fuel consumption.          The system also provides the diagnostic capability of monitoring fuel flow rate while the engine is not running.
