Abstract: An alignment apparatus for use on a well derrick or drilling rig for engagement with a pipe section either being connected to or disengaged from the upper end of pipe string within a well bore hole.  The apparatus includes a supporting frame for connection to the framework of the derrick and carrying a head assembly for engaging an upper pipe section in a manner to align the pipe section with a pipe section within the bore hole and yet allowing rotation of the upper pipe section.  The head assembly includes a fixed pipe engaging member and movable arms pivotable to a closed position, the pipe engaging member and the arms all having pipe engaging surfaces.  Adjustment mechanisms are provided to accomplish positioning of the fixed pipe engaging member and the arms so that the pipe engaging surfaces of the member and the arms can be selected whereby the surfaces are each spaced from the aligned central axis of the pipe section a distance slightly greater than the radius of the outside diameter of the pipe when the arms are moved to a closed position.  The apparatus is capable of quick and accurate alignment of pipe sections and may be readily adjusted to permit use with a variety of sizes of pipes.

Abstract: A gateway system for connecting first and second communication networks has first and second network end nodes and a protocol converter. The gateway system operates to provide input-output services of both network protocols to users of both networks in communicating through the gateway system. The gateway system employs associated complement protocol circuits in the end nodes and the protocol converter to provide these services. An efficient technique for generating the complement protocol of a first network is to prune finite state machines representing the operation of the second network protocol to provide the services of the second protocol that are not provided by the first protocol. The complement protocol circuits for the second network are then constructed based on the pruned finite state machines representing the operation of the first protocol.

Abstract: A chair-borne musical instrument support that is both adjustable and portable.  The musical instrument support includes a seat portion having an adjustably attached support arm with an instrument rest attached to the top thereof.   The musician places the seat portion of the device on the seat of a chair, and then sits  on  the  seat  portion.    The  support  arm and instrument rest extend upward near the front edge of the chair and between the legs of the musician.  The weight of the musician sitting on the chair holds the device  in  place.     Alternatively,   the  musical instrument support may be held in place on a chair by adjustable straps.   The base of the tuba is then placed upon the instrument rest which is covered with a non-abrasive, non-skid surface.  The support arm and instrument rest may be adjusted vertically up or down to a comfortable height.  The instrument then rests in the same position as if it were being held on the musician's lap, but now it does not have to be borne by the  musician's  legs.    The  musical  instrument support is not permanently attached to the chair; therefore,  the  support  may be  easily removed and carried with the musician or stored for later use. Several  embodiments  of  the  present  invention  are contemplated  which  are  designed  to  be  used  by different size musicians and with different types of instruments.

Abstract: An improved compound transmission design is provided for reducing gear hopout, particularly during PTO operation.   In this design, a spindle is rigidly secured to the input shaft, and a headset/fourth gear is rotatably mounted on a spindle by means of  a full compliment needle bearing.  A splitter gear is rotatably mounted on the input shaft and includes a sufficient diametral float with respect to the input  shaft to minimize  tipping  of  the  gear  while  maintaining significant torque balance between countershafts.  This configuration maintains concentricity in parallelism of the headset/fourth gear and splitter gear with respect to the synchronizer clutch in order to prevent gear hopout.
