Abstract: ABSTRACT OF THE DISCLOSURE         A sheet jogger to justify and align a stack of sheets into a registered bundle which is subsequently discharged into a bin.  Prior to discharging of the bundle, the stack of sheets can be stapled.  Each bundle is offset from every other bundle when discharged into the bin.  Sheets are fed onto a jogging deck by at least one conveyor roller to abut against at least one gate finger at the end of the jogging deck.  A back jogger aligns the sheets into registration against the gate finger and a left side jogger assembly jogs the sheets into alignment against a right side jogger assembly.  The gate fingers drop down and a lower eject roller rises above the jogging deck to engage a bottom sheet of the stack thereby engaging the stack against an upper fixed pressure roller.  On the next jogging operation, the initial jogging operation is repeated and the left side guide assembly and right side guide assembly return to a home position prior to ejection of the aligned bundle thereby offsetting the ejected bundle a distance equal to travel of the left, side guide assembly.  All mechanical jogging operations are controlled by a cylindrical control means having an axial curved circular detented jogger cam supported on a radial detented hub mounted below the jogging deck.  A stapler and corresponding anvil mounted on the jogging deck can staple each aligned justified bundle of sheets together.

Abstract: ABSTRACT OF THE DISCLOSURE        Each of a plurality of data modules employing commercially available microprocessor circuitry, process pulse rate information from a plurality of remote monitors to develop a digital indication of a desired parameter, i.e., radiation level.  A digital check module, incorpor-ating microprocessor electronics comparable to that of the data module, scans the respective data modules to determine the operational integrity of the data modules and auto-matically assumes the operational responsibility of a data module determined to be operating improperly.         While the radiation level is proportional to the rate of the pulses developed by the radiation monitor the instantaneous pulse rate is random.  The data modules and check module are digitally designed, incorporating com-mercially available micro-computers, to determine the true average rate of random pulses or events and to automatically optimize the trade-off between statistical error and system response time.

Abstract: ABSTRACT     A progressing cavity, positive displacement rotary pump for liquid or semiliquid material, having a specially designed flexible coupling shaft for connecting a drive shaft to an orbital rotor.  The pump components include a tubular stator with an interior helical surface and a hollow tubular orbital rotor within the stator operably connected to the shaft and having an exterior helical surface.  The rotor and stator define therebetween sealed pumping cavities that advance axially as the rotor rotates and orbits within the stator.  The rotor has a tapered socket with a polygonal transverse cross-section (e.g., pyramid-shaped) at its outer end.  The rotor is coupled to the rotor drive shaft by the flexible coupling shaft that extends through the hollow rotor and that has an enlarged taper-ed head formed to fit tightly in the socket and be retained therein by a threaded fastener.  The opposite end of the coup-ling shaft is connected to the drive shaft outside of the rotor.          The coupling shaft flexes to accommodate orbital movement of the rotor during operation of the pump.  Also, a unique seal retainer is used to locate a packing-gland-type shaft seal for the drive shaft.  The retainer facilitates removal and replace-ment of the seal components.
