Abstract: A control system for power tongs comprises two tongs torque limiters, one of which limits tongs torque to a very low (hand-tight) level; the other limits torque at full makeup to, for example, 2000 ft. lb. The hand-tight torque limiter is manually or automatically disabled after the hand-tight level is reached. The system enables the operator to verify that the threads are properly engaged before applying full torque to the connection. The tongs have a very high reduction ratio, so that torque rises very slowly and can be more accurately controlled.

Abstract: The invention relates to a guide bushing used to maintain alignment of a rotary shaft and in particular to a guide bushing for use as a mining deck bushing. When drilling blast holes in surface mining operations, it is conventional to pass the drill pipe through a deck bushing located on the floor or deck of the blast hole drill. During drilling operations the drill pipe has a tendency to run off laterally, and vibrate vertically. The purpose of the deck bushing is to keep the drill pipe as straight as possible, and prevent wear of the more costly deck. The present invention provides a guide bushing for use as a deck bushing and is equipped with a rotatable inner sleeve which is supported by angular journal bearing surfaces and ball bearings located in elongate annular grooves, which allow the guide bushing to maintain alignment of the drill pipe without premature failure of the ball bearings, grooves or other bearing surfaces.

Abstract: The herb package described is made of a synthetic foil having therein plural perforations for allowing fluids, but not solids, to exit and/or enter the package. The perforations are formed by needling, created inward or outward deformation of the foil at each puncture point, whereby each perforation tends to act as a one-way valve in a direction corresponding to the direction of needle penetration. Some of the perforations are formed by inward needling, some by outward needling, so that pressure cycling pumps water through the package contents.
