Abstract: JOB RECOVERY METHOD AND APPARATUS                Abstract of the Disclosure Method and apparatus are described for job re-covery when jamming of copies occurs in copying devices generating duplex copies electrophotographically from either simplex or duplex originals.  Recovery from jams while copying the first side of simplex or duplex originals can normally be immediately effected during the initial, or normal, run, after clearing the jam.  Recovery from jams during copying of the second side is effected by clearing the jammed copies from the copying device, optionally in-serting blank sheets as the initial copying run is continued to flag the position of each of the removed jammed copies in the generated stack of copies, rerunning the originals through the copying device after completion of the initial copying run with duplex copies being generated only as necessary to replace jammed copies occurring during the initial run, and then inserting the duplex copies last made in the proper positions in the stack of copies made during the initial run, which copies replace the blank flagging sheets, if utilized.   The apparatus includes a plurality of counters, memory registers and comparators interconnected by logic circuitry to semi-automatically effect job recovery due to jammed copies occurring during duplex copying from either simplex or duplex originals.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a device for axially locating a driving spool on a drive shaft of a line shaft live roller conveyor.  A conveyor pass line to carry boxes or other articles is formed by the upper surface of a number of rollers which are driven from a corresponding number of spools on a single drive shaft extending transversely beneath them.  An elastomeric drive belt extends between each driving spool on the drive shaft and a groove in a respective one of the rollers. The rollers are independently driven to provide for conveyor "accumulation" by having a relatively loose frictional fit between the spools and the drive shaft.  The fact that each drive belt must turn through an angle of approximately 90° between the spool and the roller results in a tendency for the spools to shift axially along the drive shaft with the intermittent application of load.  This causes the drive belts to stretch and eventually lose their power and sometimes jump off of the spools.          The present invention provides a locating device with a C-shaped body with a mouth which may be transversely snapped over the drive shaft.  The locating device is formed of a resilient material and grips the drive shaft to securely retain it in the desired axial position.  A locating device is normally positioned adjacent each spool on the downstream side to prevent axial shifting of the spool when the load is removed.  The locating device has a smooth side wall to minimize friction with the spool and may be manually relocated along the drive shaft to intention-ally shift the spool to maintain a desired tension in the elasto-meric drive belt to compensate for stretching.  The locating devices may be quickly and easily installed and relocated without removing the spools as was the case with the previous cylindrical spacers, nor do they transmit any forces between adjacent spools.

Abstract: Abstract of the Disclosure An air core gage having a pair of coils in quadrature to drive a pointer has the first coil energized by a relatively constant reference current while the second coil is energized by a current which varies as a tangent function of the input quantity in order to drive the pointer through an octant of the gage.  The current polarity to the second coil is reversed and the current is again varied in the same manner to vary the pointer through a second octant.  Then, the reference current is applied to the second coil and the current is varied in the first coil according to the tangent function to drive the pointer through a third octant, and so on for a wide angle pointer drive.  When the input quantity is a frequency, the driving circuit is conveniently a digital circuit including a ROM which stores the tangent function of the input quantity and a steering logic circuit which selectively applies the steady state and the variable signals to the gage coils to effect the appropriate pointer movement.
