Abstract: ABSTRACT OF THE DISCLOSURE    A system for accurate web feeding in conjunction with a rotary die cutter or printer where the length of web treated per revolution of the treatment roll is substantially less than the peripheral length of the treatment roll at its effective diameter wherein scrap between treated areas is eliminated through a "net pull-back" of the web during the portion of the cycle when the web is free of the treatment means.  In die cutting the system accommodates all the inherent overfeed including that generated by die engagement and disengagement from the web both respectively before and beyond the aligned centers of the impression and complementary rolls thus permitting two-stage cutting of blanks on successive rotations of the impression roll as is frequently required by the most efficient layout pattern on the treatment rolls.      In die cutting the impression roll is maintained at constant peripheral velocity and the web, while engaged by the die, travels at the peripheral velocity of the impression roll.  As the trailing edge of the die approaches the nip formed by the impression and complementary rolls, one or both of the feed rolls driven by the web is clutched into a cam mechanism for positive driving at a constant velocity equal to the die-induced velocity of the web.  This constant velocity driving of the web jointly by the die and feed rolls continues until the die releases the web beyond the aligned centers of the treatment rolls when the web comes under exclusive control of the feed rolls.  The cam-controlled velocity of the feed rolls and web then decreases to zero, is maintained at zero velocity for a period of time dependent upon the peripheral distance between the die trailing edge and die leading edge, and is then driven in a reverse direction for a fixed distance and accelerated forward to the peripheral velocity of the impression roll at which point, during the constant velocity motion of the feed rolls as induced by the cam mechanism, the leading edge of the die engages the web at the exact point of disengagement of the trailing edge of the die on the previous cycle.          While still in the constant velocity portion of the feed roll drive cycle, the clutch is disengaged and the feed rolls freed for web induced travel, the web itself now being driven by the die engaged therewith.

Abstract: ABSTRACT OF THE DISCLOSURE:            In  a  quadrupole  ion  store  or  ion  trap  type mass spectrometer, significantly improved mass selection is achieved by scanning the applied RF and DC voltages or the  frequency  .omega.  sequentially  to  render  unstable trapped ions.  These are passed out through apertures in an end cap to a high gain electron multiplier to provide a signal indicative of the ion mass.  Sensi-tivity and mass resolution is also enhanced by oper-ating the ion trap at a relatively high pressure in the range 1 X 10-1 to 1 X 10-5 torr.  The presence of collision  gas  molecules,  such  as  helium,  improves sensitivity  and mass  resolution.   In addition,  the structure itself is built of stacked units, sealed by O-rings, which are easily disassembled for cleaning.

Abstract: METHOD AND APPARATUS FOR MANUFACTURING                  WAFERS                            ABSTRACT Wafers are produced by guiding a sheet of bread having friable outer crusts and   relatively soft center through wafer forming apparatus.  The apparatus includes a pair of rolls, one of said rolls, i.e., a cutting roll having one or more wafer forming recesses or cavities therein and the other roll being a pressure roll which operates in rolling engagement with the cutting roll.          As the sheet of bread is introduced into the nip formed between the two rolls the pressure roll acts to press the bread into the cavity or cavities on the cutting roll and into engagement with the edges of the cavity or cavities to cut wafers from the sheet of bread,  Each cavity is configured to have a bottom surface which rises as a gradually tapering wall to a cutting edge which is coterminious with the surface of the cutting roll.  Continuous production of wafers is possible with the edges of the wafers being sharply defined, free of undesirable crumbling and devoid of fracture lines, all of which otherwise render the wafers com-mercially objectionable.  The wafers may be scored or impressed with a design in their surface as they are produced.
