Abstract: TEAR STRIP OPENABLE SHIPPING/DISPLAY CONTAINER     ABSTRACT A shipping carton or container that can be readily opened and converted into a display tray without having to use a knife or other sharp instrument. The carton is formed from a blank having four sidewalls and hingedly connected top and bottom end panels. The sidewalls have a line of severance running circumferentially around the carton that defines a continuous butt joint separating the carton into a top cover section and a bottom tray section. A wide tape having a narrow tear filament or strip attached to its inner surface is adhesively attached to the sidewalls' outer surface such that it bridges the butt joint and holds the carton's top and bottom sections together, the tear strip being substantially superimposed over the butt joint. Pulling the tear filament neatly splits the wide tape and separates the carton's top and bottom sections.

Granted: 1995-06-27
Abstract: A method and apparatus for minimizing the visual degradation of a typeface wherein the need for the manual input of skilled technicians is eliminated and the important visual components of each character and the relationship of the visual components of each character with the other characters of the typeface are preserved. The characters are analyzed to determine the visual components in the horizontal and vertical direction which comprise each character and the priority of adjustment. Using the visual components determined, starting with the highest priority component, the coordinates describing each character are adjusted according to rules which are dependent upon whether the strokes formed are oriented in the horizontal or vertical direction. The adjustment of the lower priority visual components isdependent on the previously aligned components. The important visual components in the diagonal direction are subsequently adjusted in accordance with similar sized visual components in the horizontal and vertical direction wherein the dimensions of the adjusted horizontal and vertical components are maintained.

Abstract: 54,109 ABSTRACT OF THE DISCLOSURE    A method of analyzing crack growth in an object takes into account interaction between indications of discontinuities that can become cracks and also effects of creep on crack growth to provide a more accurate analysis of crack growth.  The remaining life of an object is determined by calculating a critical crack size from worst case conditions and defining loading blocks representing cycles of temperature and stress changes.  The rate of growth in the size of indications estimated from non-destructive evaluation is accumulated based upon the defined loading blocks until one of the indications reaches the critical crack  size  The allowable stress which can be placed upon the object can be calculated from the same estimates of indication size and assuming different stress levels until a desired lifetime of the object is attained when one of the indications reached the critical crack size. An initial allowable discon-tinuity indication size can be calculated by setting a current crack size to the critical crack size and decrementing the current crack size until the defined loading blocks have been applied to the current crack size in reverse order which calculating the effective crack growth rate including the effects of creep.

Title: Feeder for shape unstable articles

Granted: 1992-11-17
Abstract: Abstract of the Disclosure A feeder for shape unstable articles such as pads for absorbing body fluids has an upright hopper having top and bottom openings for receiving and dis-charging pads.  First and second rotationally driven upper pulleys having a plurality of round belt receiv-ing grooves in their peripheries are mounted adjacent the bottom opening of the hopper on opposite sides of the vertical center line of the hopper.   Third and fourth idler pulleys are arranged in laterally spaced apart relationship and symmetrical to the center line of the hopper at a lower level than the first and second pulleys.  Because the lower pulleys are closer to each other than the upper pulleys, the belts con-verge toward each other such that articles which set-tle out of the hopper finally become wedged between the belts proximate to the lower pulleys.  A stepping motor is energized to drive the pulleys and translate the belts so that the lowermost article in the stack is dispensed from between the lower pair of pulleys by reason of being frictionally engaged at its edges by the belts on the grooved pulleys.  The stepping motor is started at the moment a pad should be dispensed and is stopped in response to the pad dropping across the beam of a photosensor so the feeder is self-timing. Thus, the feeder is self-adjusting for each individual article ranging from a short feed time for a com-pressed article to a longer feed time for the next article  which may  not  be  compressed  and,  hence, thicker.

Of particular utility is the separation of cells from peripheral blood mononuclear cells, where members of the lymphoid or myeloid lineages may be isolated and used for research, diagnosis or therapy. Also of interest are cellular separation from bone marrow, tumor suspensions or lymphoid tissue suspensions, where cells can be isolated and used for a variety of purposes.  The separated cells may be homogeneous, free of exogenous biologicals, viable, capable of replication and exhibit their full complement of biological activities.  Multiple phenotypes can be captured simultaneously.  Captured cells can be specifically activated with cytokines and antigens to provide cells which are MHC restricted and have antigen-specific effector functions.

Abstract: SYSTEM FOR ENABLING DESCRAMBLING ON A SELECTIVE-SUBSCRIPTION    BASIS IN A SUBSCRIBER COMMUNICATION NETWORK            ABSTRACT OF THE DISCLOSURE      A  system  in   a  subscriber  television  network  for enabling  descrambling  of a received scrambled signal on  a prepaid basis and/or an impulse-purchase basis.   A received mask  signal  uniquely related to the  scrambled  signal  is compared  with  a received authorization  signal  indicating whether   the  subscriber  is authorized  to  receive   the scrambled signal on a prepaid basis and a prepaid signal for enabling  descrambling is provided when the compared signals match.   A  not-prepaid signal is provided when they do  not match.  A  received  cost signal indicating the  charge  for descrambling  the  scrambled signal and  a  received  credit signal  indicating  the subscriber's accumulated credit  are processed   with  reference  to  a  stored  record  of   the subscriber's prior accumulated charges to determine  whether the  subscriber  has sufficient available credit to pay  for descrambling of the scrambled signal.   If a program is  not prepaid   and  if  sufficient  credit  is   available,   the subscriber  is given  the option of causing the signal to be descrambled  on  an impulse-purchase  basis.  To  prevent  a subscriber  from obtaining descrambling through such  deceit as  changing  the mask,  authorization,  cost and/or  credit signals,  these signals are processed with key signals which are  used  in  scrambling and  descrambling  the  television signal  such  that descrambling is prevented if any  of  the mask et al signals is changed.
