Abstract: A method and apparatus for manufacturing decals from a web of decal material, wherein core portions of waste material in the decals automatically can be removed from the decals. In one aspect of the invention, backing material is stripped from the decal material; the decal configurations are cut into the decal material; the waste exterior portion of the decal material is removed from the decals while the decals are retained in position on a vacuum wheel; and the core portions are removed by the vacuum in the wheel through enlarged openings opposite the core portions on the decals. In another aspect of the invention, the decal configurations are cut into the decal material while it remains on the backing material; the exterior waste portions are removed; and the core portions are removed by passing the backing material over the sharp edge of a peeling bar while pressing the decal portion downwardly on the backing material.

Abstract: Document detector and collector for detecting and collecting identifiable documents from a high speed stream of documents. A plurality of documents including identifiable documents are fed along a path. A detector detects the identifiable documents. A table is mounted above the document path to receive the identifiable documents. A first vacuum wheel responsive to the detector, removes the identifiable documents and feeds the removed documents to a second vacuum wheel. The second vacuum wheel delivers the documents to the delivery table.

Abstract: Removing dice (16) from a wafer (10) which has been attached to a tape layer (12, 14) and severed into individual die (16) leaving the tape layer (12, 14) in one piece is accomplished by attaching the tape layer (12, 14) to a length of adhesive tape (18). The adhesive tape (18) is passed across a surface (20) and through a slot (38) in the surface (20) causing the die (16) to pass across the slot (38) and away from the tape layer (12, 14) which remains attached to the adhesive tape (18).

Abstract: A method and device for emptying a belt reel or bobbin filled with tobacco leaves or portions thereof, the belt being withdrawn from the bobbin and wound on a reel, while each time the tobacco leaf portions are removed from the corresponding strip of belt, wherein prior to the removal of each tobacco leaf portion the belt is stretched in excess of the normal tensile force required for winding off the belt in order to detach the tobacco leaf portion from the belt, which additional stretching effect need only be very slight in order to pick up all tobacco leaf portions without disturbance.

Abstract: High speed document processing and sorting apparatus. A stream of documents is guided along a path at high speed. A detector is mounted along said path to detect identifiable documents. A magazine is mounted to receive the detected documents. A vacuum wheel is mounted to remove the detected documents from said path to said magazine. The vacuum picker comprises a vacuum wheel mounted a predetermined spacing over said path, the vacuum wheel having a surface speed equal to the high speed document speed. A solid wheel is movably mounted below said vacuum wheel and below said path. A detector control moves the solid wheel and document up into contact with the vacuum wheel when it is desired to remove a document moving at high speed.

Abstract: The removal of so-called zip-tape from reclaim tobacco is achieved by use of an elongate vibratory conveyor having grooves extending longitudinally therewith and of longitudinal depth profile preselected from groove-containment of the reclaim tobacco, except for the zip-tape content thereof. Rollers having surface affinity for the zip-tape are arranged in overlying relation to the conveyor surface and groove rises, and are disposed in acute angle relation with the conveyor feed direction. The rollers are supported for joint movement with the conveyor so as to be maintained in fixed relation to the conveyor surface during vibration. Zip-tape encountered by the surfaces of the rollers is withdrawn from the conveyor grooves and is displaced successively transversely of the conveyor for collection aside the conveyor.

Abstract: In order to sort a quantity of hard gelatin capsules of the type having at least a top and bottom and being filled with powdery contents, and to remove therefrom defective capsules which do not have a top or which may be cut or deformed in some way, the apparatus includes a first member with apertures for the capsules and a second member with similar apertures which are aligned with the first apertures in a first relative position of the two members. By applying suction to the top of the second member, intact capsules are urged into the second member while defective or deformed capsules are retained in the calibrated bore of the lower member. The two members undergo a relative displacement subsequent to which a discharge device moves rods into the individual orifice causing the discharge of intact capsules and defective capsules into different receiver chutes.

Abstract: Sorting apparatus and method comprise a viewing area, a removal area, and a conveyor for passing a thin bed of indiscriminately mixed items first through the viewing area and then through the removal area. Radiant energy, which includes bands of two mutually different wavelengths that are reflected in a predetermined relationship by some of the items and in other than that relationship by the other items in the mixture, is flooded into the viewing area as an integrated spread throughout the area from preferably special light fixtures producing both visible light and infrared radiation.

Abstract: The invention discloses a method and apparatus which allows the sorting of particles or cells in accordance with their physical and/or chemical properties such as size, DNA and/or protein content.

Abstract: A conveying system incorporating an apparatus for detecting and rejecting downed and damaged containers, such as open ended cans. The conveying system includes a pair of endless belt conveyors which are spaced apart longitudinally and are adapted to convey cans in an upright condition. The upright cans are adapted to be transferred between the conveyors by a vacuum transfer mechanism which is located above the adjacent ends of the conveyors, the transfer mechanism includes an endless perforated belt that travels across the open bottom of a housing which is divided into a series of chambers. The chambers are subjected to a vacuum which acts to hold the upright cans against the perforated belt so that the cans can be transferred by movement of the belt from one conveyor to the other, while downed cans are ejected from the conveyor system.

Abstract: Inspection is effected by clamping cans between a holder and a photosensitive device which holders and devices are disposed in opposed relationship in a plurality of sets, illuminating exterior of the cans to project light through any opening in the can to the photosensitive device, sensing such light and sending electrical signals to an electronic memory to sort good cans from leakers; the photosensitive device includes an array of directional photodarlingtons one group of which detects openings in can flanges and another group detects openings in can bodies.
