Abstract: CONTROL SYSTEM FOR A MULTIPLE SPINDLE MACHINE            ABSTRACT OF THE DISCLOSURE     This disclosure deals with a machine for simultaneously tightening a plurality of threaded fasteners.  The machine includes a plurality of torque applying units, one for each fastener, which engage and torque the fasteners.  Each unit includes a spindle which engages the fastener and a torque sensing circuit which generates a torque signal representing the magnitude of the torque being applied.  A torque control circuit of each unit prevents torquing to above a preset upper limit.  A central control circuit receives the torque signals from all of the units, makes a comparison of torque values to identify any unit where the applied torque is greater than that of the other unit or units, and prevents such an identified unit from continuing to apply torque until the other unit or units applies torque essentially equal to that of the identified unit.  The torque signals from the units may be averaged and the torque signal of each unit compared with the average.  If only two units are provided, one torque signal may be compared with the other torque signal.

Abstract: ABSTRACT OF THE DISCLOSURE       A fire rated dry wall ceiling support system having fixed, aligned main beam members spliced together in a manner so as to absorb longitudinal compression, as for example resulting from thermal expansion during a fire. Each main beam includes a web surmounted by a bead with flange portions extending laterally outwardly from the web.  Each web end includes a tongue extending axially outwardly for locking engagement with the adjacent beam member web and is so configured that the tongues fold in a longitudinal manner and become laterally displaced out of the normal plane of the tongues when the beam members are longitudinally compressed towards one another.  Accord-ingly, the  bead means become laterally displaced while moving towards one another in a longitudinal direction and may in fact overlap one another in a longitudinal sense. The system further includes support channels disposed trans-versely to the main beam members and engaged therewith.  The main beams include pairs of longitudinally spaced slots which receive the ends of the transverse cross channels from both sides of the main beam.  The ends of the cross channels are locked in the main beam slots.  The slots and cross channel ends are designed to absorb thermal expansion in the transverse cross channels during a fire situation. In addition the cross channels include a horizontal base portion which provides an effective mounting surface for dry wall ceiling panels.
