Abstract: ABSTRACT    An apparatus for determining if a received binary word corresponds to the true or complement version of a stored binary word includes means for serially multiplexing the bits of each binary word to the inputs of an exclusive OR gate.  The exclusive OR gate generates a logical high signal each time a mismatch occurs.  These signals are applied directly to an error counter and, after inversion, to a match counter.  The contents of the error counter and match counter are compared to a stored threshold number.  A first signal is generated if the contents of the error counter exceeds the threshold.  A second signal is generated if the contents of the match counter exceeds the threshold.  Upon the occurrence of both signals, the serial comparison process is terminated.

Abstract: Boards of lumber or similar material having knotholes or other defects in an edge region are repaired by cutting an opening in the edge region to remove the defect and by filling the opening with a conforming plug formed of hardened mastic or of pieces of solid material which are adhered together.  The opening extends inward from the edge of the board and is of greater extent at a location spaced inward from the edge than it is at another location that is closer to the edge.  The expanse of the opening preferably increases at a first depth within the board and decreases at a second depth within the board.  The configuration of the opening interlocks the conforming plug into the board thereby preventing ejection of the plug.

Title: Apparatus and method for producing a bent laminate
Inventor: SUSKA ALEX
IPC: B31F1/00
Filed: 1990-05-29
Abstract: ABSTRACT      An apparatus and method is disclosed for the bending and pressing of laminations into 2-dimensional or 3-dimensional curves.  The apparatus includes a pair of spaced apart rotatable clamps for the clamping of the laminations at spaced apart locations.  At least one of the clamps is movable towards the other clamp.  Counterclockwise rotation of the clamps bends the laminations held by the clamps.  A clamping force of at least one of the clamps is controllable so that the laminations may be bent while a mutual sliding movement of the laminations in at least one clamp is permitted.  The laminations are bent to a radius larger than a desired radius.  At this point, the clamping pressure is increased to prevent the mutual sliding movement so that upon further bending of the laminations, the outer laminations are pressed against the inner laminations at a substantially evenly distributed force along the bent section of the laminations.  The apparatus is easily adaptable to produce different shapes and sizes of 2- and 3-dimensional curvatures and permits the fast and economical bending and compression of a workpiece having individual layers.
