| Number | Title | Issue Date |
| 3980553 | Automatic feeding and sorting equipment for electrical components An automatic testing machine which picks up electrical components such as transistors from a feed mechanism and feeds them to spaced clamped positions at the periphery of a test wheel. The test wheel is turned by a stepper motor and the electrical devices... | 09/14/1976 |
| 3977526 | Tracking systems for sorting apparatus A tracking system for a sorting apparatus for sorting pieces of material moving through a sorting zone in a wide path random stream has a light scanning device which makes repeated scans across the sorting zone to detect light reflected from the pieces of... | 08/31/1976 |
| 3975261 | Sequential event memory circuit for process and quality control An electrical system is disclosed, in which a conventional detector device produces a signal upon its sensing a characteristic or property of a conveyed object at a location upstream, on a conveyor system, from a control location at which the object is to... | 08/17/1976 |
| 3974888 | Method of weighing and apparatus therefor A method of weighing and an apparatus therefor, wherein articles varying in unit weight are continuously weighed by a single weighing machine to classify them into three ranks, one for articles having error weights outside the allowable error limits, anot... | 08/17/1976 |
| 3969227 | Photoelectric inspection of transparent or translucent medicinal capsules In a capsule filling machine, capsules held pneumatically against the periphery of a transporting disc are photoelectrically inspected by two light beams, both oblique with respect to the disc axis. Electrical gating and delay circuitry effects pneumatic ... | 07/13/1976 |
| 3941686 | Inspection machine memory An improved memory for a glass container inspection machine. In one common form of glass container inspection machines, the containers are indexed through multiple stations where they are inspected for various attributes. Rejection of defective containers... | 03/02/1976 |
| 3933247 | High speed magnetic core handler An orientation system forms part of a magnetic core handling system using an oscillating feed cup causing magnetic cores to roll across an arcuate surface into a tapered slot and communicate with an index feed wheel. The index feed wheel has 50 slots form... | 01/20/1976 |
| 3933248 | Bird-swing detector An improved "bird-swing" detector which has a downstream rejection system. An optical type bird-swing detector inspects glass containers as they move therethrough on a conveyor. A container exhibiting a bird-swing defect causes generation of a rejection s... | 01/20/1976 |
| 3930994 | Method and means for internal inspection and sorting of produce Apparatus and method for automatically evaluating articles particularly citrus fruits, on the basis of the uniformity and non-uniformity of their transparency to light rays and selectively separating them into different grades according to such evaluation... | 01/06/1976 |
