  "abstract": "A conveyor system for delivering work pieces to a predetermined area comprising a first conveyor, a second conveyor disposed at an angle to the first conveyor, a mechanical brain, and a transfer apparatus (arm) at the juncture of the first and second conveyors. The mechanical brain has a shim, a rotating disk and sliding plates on the disc that are temporarily moveable to form a protrusion that rotates with the disc. The disc rotates at a speed that is a function of the speed of the first conveyor and the protrusion activates a device to create a light path transverse to the first conveyor near the first and second conveyor juncture just prior to a workpiece entering such juncture. The protrusion is returned to its normal state, subsequent to the creation of the light path, by the coaction of the rotating disk and the shim. The workpiece interrupts the light path causing the transfer apparatus (an arm) to divert the workpiece to the second conveyor and upon the reestablishment of the light path, the arm is caused to retract.",
  "claims": [
    "1. A mechanical brain comprising: p1 (a) a rotatable disc having first and second surfaces and an outer peripheral surface; (b) a plurality of plate members, each plate member (i) having two major surfaces and disposed so that each major surface of each plate is in sliding contact with a major surface of another plate member and (ii) having first, second, third, and fourth edges, said first edge in sliding contact with the outer peripheral surface of said rotatable disc; a containing member, circumscribing said plates, in sliding contact with said second edges of said plates, said containing member mechanically securing the plates to said outer peripheral surface of said rotatable disc so that said plates may move relative to one another, the outer peripheral surface of the rotatable disc and the containing member; and, (d) first outer member disposed in face-to-face relationship with said first surface of said rotatable disc, a first striker including a first striker member disposed on said first outer member in confronting relationship to the third edges of said plate members for moving a first number of said plates from a first to a second position and a first shim member disposed on said first outer member so that said shim comes in contact with a second number of plates in their second position and moves them from their second to their first position upon rotation of the rotatable disc.",
    "2. The mechanical brain of claim 1 further including a second outer member disposed in face-to-face relationship to said second surface of said rotatable disc, a second striker including a second striker member disposed on said second outer member in confronting relationship to said fourth edges of said plates for moving a second number of said plates from a first to a second position and second shim member disposed on said second outer member so that said second shim member comes in contact with the first number of plates in their second position and moves them from their second to their first position upon rotation of the rotatable disc.",
    "3. The mechanical brain of claim 1 further including a control with first and second on-off switches, the first control on-off switch in pneumatic communication with the first striker and adapted in its \"on\" state to activate the first striker member of the first striker and the second on-off switch in pneumatic communication with the second striker and adapted in its \"on\" state to activate the second striker member of the second striker.",
    "4. The mechanical brain of claim 2 further including a first brain switch, having an \"on\" and \"off\" position, disposed on said first outer member and in confronting relationship to the third edges of said plates so that the second number of plates in their second position come in contact with said first brain switch and place it in its \"on\" position prior to said second number of plates coming in contact with said second shim member upon rotation of the disc.",
    "5. The mechanical brain of claim 2 further including a second brain switch, having an \"on\" and \"off\" position, disposed on said second outer member in confronting relationship to the fourth edges of said plates so that the first number of plates in their second position come in contact with the second brain switch and place it in the \"on\" position prior to the first number of plates coming in contact with said second shim member upon rotation of the disc.",
    "6. The mechanical brain of claim 5 further including a first photoelectric device in electrical communication with the second brain switch and responsive to the second brain switch being rendered to the \"on\" position to complete a first electrical circuit through the first photoelectric device.",
    "7. The mechanical brain of claim 4 further including a second photoelectric device in electrical communication with the first brain switch responsive to the first brain switch being rendered to the \"on\" position to complete a second electrical circuit through said second photoelectric device."

  "description_excerpt": "This application deals with the same general subject matter as disclosed in our co-pending application entitled \"Conveyor\", filed Nov. 28, 1986, Ser. No. 06/936,109.\n\nIn the furniture industry a piece of upholstered furniture is customarily packaged by heat shrinking a heat shrinkable sheet of plastic onto a piece of furniture. This is usually accomplished by draping a heat shrinkable piece of plastic over the piece of furniture (workpiece) and then conveying the draped workpiece into a furnace where hot air at approximately 375° F. is blown causing the plastic to shrink and take the shape of the outside contour of the workpiece. Known prior art employing this process uses a conveyor to convey draped furniture to a furnace, a conveyor to convey the plastic-draped workpiece through the furnace; and, another conveyor to convey the packaged workpiece (piece of furniture about which plastic has been shrunk) from the furnace to a storage area. Throughout this application, the conveyor that conveys the workpiece to the furnace, the furnace conveyor and the conveyor that conveys packaged workpiece from the furnace will be referred to collectively as the first conveyor.\n\nOne of the problems in using this type of prior art apparatus is the distribution of the number of packaged workpieces after they are discharged from the furnace. More often than not, there is a need for a particular packaged workpiece be shunted to a first predetermined area and another following packaged workpiece would need to be shunted to a second predetermined area.",
