Abstract: Disclosed  is  a  perforator  blade  for  core  wound  paper products, such as toilet tissue and paper towels.  The perforator blade has a relatively narrow notch width and a relatively narrow tooth width.  As the notch width and tooth width of the perforator blade are decreased, the total notch width, which is the aggregate of  the  width  of  each  notch  across  the  total  width of  the perforator blade, is similarly decreased.     A  perforator  blade  according  to  the  present  invention provides   very   high   perforation   bond  strengths,   joining superimposed  plies  in  face-to-face  relation,  without  unduly increasing the tensile strength of the lands bridging adjacent sheets of the core wound paper product.  Also,  individual  tooth flexibility  is  increased  according  to  the  present  invention resulting in enhanced perforator blade life and perforation bond quality.   Perforated  paper  products  according to  the  present invention  also  exhibit  less  lint,  reducing  hygiene  problems, reduced  occurrences  of  sheet  tearing  during  dispensing,  and provide a smoother, better finished appearance during dispensing.

Abstract: A motion transducer for measuring the displacement of, for example, shafts in gas control modules. The shaft 14 carries two magnets 10, 12 each of hollow cylindrical form, the magnet 10 presenting a south pole everywhere over its external cylindrical face and the magnet 12 presenting a north pole everywhere over its external cylindrical face.  The shaft 14 moves vertically past an array of Hall-effect sensors 18-24 to produce sinusoidal voltage outputs at the sensors. The outputs are combined in a summing amplifier (Figure 3). The combined output is not affected by rotation of the shaft and magnets nor by tilting or sideways displacement of the axis 16 of the shaft. That is because no matter what the rotational position is the sensors are always subjected to the same magnetic field and, if the shaft tilts or is displaced sideways an increased field at some sensors is compensated by a decreased field at others.
