Abstract: Apparatus for error proofing in manufacturing and kitting operations and the like. A frame having two or four frame members utilizes light emitters and sensors on opposite sides to determine when the plane of the frame has been broken, and storage areas behind the frame have been accessed. This information is compared to programmed information to verify whether errors in accessing the storage area have occurred. The plane of the frame has a plurality of penetration zones distinguishable by their respective corresponding emitter and sensor pairs.

Abstract: A system and method for the repetitive selection of a group of items which utilizes a series of sensors associated mounted in a frame structure adjacent supplies of items so that the manual selection of an item or items from a supply can be monitored. A programable logic controller is utilized for allowing the system to be "taught" so that it can easily be used for the repetitive selection of many different desired groups of items without the necessity of rewiring or constructing a totally new device.

Abstract: A bend correction apparatus for bending a workpiece subject to springback, the apparatus having a pressure die for holding a workpiece, a radius die for providing a radius form about which the workpiece is bent, and a clamping die for engaging and bending the workpiece relative to the pressure die and about a portion of the radius die. A microprocessor moves the clamping die between a bend angle position in which the workpiece is bent about the radius die to a predetermined angle relative to the clamping die and a relieved position in which the clamping die is not bending the workpiece. A sensor, movable conjointly with the radius die, engages the workpiece in a springback position upon rotation of the radius die toward the workpiece and sends a signal to the microprocessor upon contact with the workpiece.

Abstract: A manifold assembly comprising a first manifold and a second manifold. The first manifold has a first hollow conduit and a first plurality of apertures through the first conduit. The second manifold has a second hollow conduit and a second plurality of apertures through the second conduit. The manifold assembly further includes at least one joining member between the first and second manifolds for joining the first manifold to the second manifold with the first conduit being side-by-side and adjacent the second conduit. The joining member includes a region of weakness for facilitating separation of the first and second manifolds.

Abstract: A manifold for a heat exchanger or the like formed from a single sheet of metal with a plurality of tubular portions formed in a row by drawing the metal sheet, and then bending the metal sheet to form at least one conduit in communication with the tubular portions for establishing a flow path therethrough.
