Title: Sorting and packing arrangement for siding panels
Inventor: GUBBELS ROGER D
IPC: B65B5/02
Filed: 1998-05-22
Abstract: A unitary panel sorting and packing machine receives vinyl siding panels from an extruded production line.  The machine includes a panel receiving section which includes lifting and flipper arms for selectively inverting panels for packing efficiency.  From the panel receiving section, the panels are transferred to a panel accumulation section. The machine also includes a box folding section for folding corrugated paper box blanks along predetermined score lines. The box folding section is preferably parallel and adjacent to the panel receiving section and the panel accumulation section and includes retractable arms which selectively position the box in a ready position for packing panels therein. After the box is full, conveyor mechanisms carry the box from the box folding section through a box lid glue applying station and then into a box end folding and gluing station.  This machine can substantially reduce repetitive stress caused injury to the operator.

Patent CA-2252205-A1 (CA)
Inventor: ECCLESTON GEORGE JAMES BARRIE
IPC: A63F9/00
Filed: 1998-11-10
Abstract: A word puzzle or game in three dimensions, enclosed within the form of a right parralelepiped or rectangular solid containing unknown words or phrases each having associated definitions constituting clues or synonyms for the solving of each individual word or phrase portion of the puzzle such as is the object of a conventional crossword puzzle, with construction such that a method is provided for the publishing and subsequent solving of the three dimensional word puzzle upon any two dimensional media surface (e.g.  magazines, newspapers, video screens). Three numerical indicia associated with each individual word or phrase portion represent the x, y, and z position of the starting cell W thin the rectangular solid puzzle object of each such word or phrase portion. The clues for solution of these word or phrase portions are separated into three groups, one group of clues being given for each of the three directions: x - Across, y - Down, and z - In, and the group wherein the clue is contained defines the direction of the word or phrase portion referenced. This provides a method whereby the entire puzzle may be solved by solution of the X (across) and Y (down) clues together, or by the Z  (in) clues alone, or by judicious combinations of all clues. The sequential presentation of vertical cross-sections or 'slices' provides solvers of the puzzle with a virtual three dimensional puzzle surface, and when these 'slices' are printed on sequential media pages requires them to repeatedly access a range of pages. When this publication is in media such as newspapers or magazines this process is much to the benefit of advertizers and publishers.
