Abstract: A variable angle flexible band clamping corner for clamping work piece angles in desired locations to permit nailing, screwing, gluing, or otherwise joining the work pieces. The clamping corner consists of two pivotable contact pads, where the face of each contact pad extends on both sides of the face of the other contact pad. The contact pads can be either constant width fingers that bypass each other when pivoting, or a wide pad with thinner fingers extending from the pad, where the fingers interleave with each other. A corner formed by two work pieces positioned between the two contact pads remains aligned by the force of the face of each contact pad. The clamping corner includes a body that receives force and transmits the force to the contact pads which hold the work piece corner in place.

Abstract: A detector device for detecting the passage of articles of a conveyor comprises an energy source element 8, an energy responsive element 10 and reflector means 27, 9 and 28, positioned so that a beam of energy from the source element 8 to the responsive element 10 first traverses the conveyor path substantially parallel and close to the conveyor surface and is then reflected back and forth across the conveyor path in a plane substantially perpendicular to the conveyor surface.
