Abstract: PCT No. PCT/DK90/00128 Sec. 371 Date Jan. 22, 1992 Sec. 102(e) Date Jan. 22, 1992 PCT Filed May 22, 1990 PCT Pub. No. WO90/14278 PCT Pub. Date Nov. 29, 1990.The invention relates to a cardboard sales and dispenser box of a pocket carry-type and of a hinged hood or a cap-like lid type. The present invention provides an effective snap-locking mechanism for engaging laterally projecting ear portions on opposed side edges of a front panel portion of the dispensing boxes. The laterally projecting ear portions engage respective recesses on the inside of opposed lateral lid skirt portions. The recesses are spaced within the inner side of the front lid skirt, adjacent to the corners thereof, and the edges of the side flap portions of the lid panel are folded flat against the outer lateral lid skirt portions constructed by the side folded outer flap portions of the front lid skirt. Thus, the hinged lid is effectively snap-locked when the projecting ear portions are received in the recesses while the lid is closed.

Title: Recognition of image colors using arbitrary shapes in color space
Inventor: TORRE-BUENO JOSE R
IPC: G06T7/40
Filed: 1990-06-08
Granted: 1996-06-11
Abstract: In  a  color  identification  system  in which  a  video signal  is  rendered  into  three  mutually  distinct  color element signals, a set of defined colors is established. The disclosed invention defines each color in the set by three  compound  color  components,   each  compound  color component being defined by pyres combination of color element magnitude ranges.   As  the color element signals change  at  the  pixel  rate  of  the  video  signal,  the invention combines them into three compound signals, each compound signal resulting from combination of a respective two  of  the  color  signals.     Each  of  these  pairwise combinations is compared with compound color component sets to determine whether the current pixel embodies a color in the set of defined colors.

Filed: 1991-08-20
Granted: 1997-02-11
Abstract: An apparatus is disclosed for selectively inverting flexible and limp planar workpieces such as fabric.  The apparatus includes a primary workpiece propeller having a cylindrical means for contacting the workpiece about a central rotating axis.  A slot of sufficient size to receive the workpiece is positioned in a substantially vertical orientation beneath the primary propeller.  The slot preferably has a flared upper end positioned directly beneath and in contact or near contact with the propeller.  The fabric is drawn into the slot by the rotation of the propeller and follows the contour of the flared open end of the slot.  The fabric enters into the slot until the trailing edge of the fabric is in contact with the primary propeller.  The trailing edge of the fabric is drawn by the propeller to the opposite side of the flared opening of the slot and is subsequently pulled out of the slot.  Collisions are prevented between workpieces by a control circuit that instructs the workpieces when to leave the apparatus.
