Patent number: 4379510Abstract: An apparatus for sorting stones contained within a supply reservoir by viewing the stones individually through a microscope includes a pick-up tube having a first opening disposed at one end thereof, the first opening adapted to form a substantially airtight seal with one of the stones. A vacuum source is connected to a second opening disposed at the other end of the pick-up tube, the second opening being in communication with the first opening. The apparatus further includes support apparatus connected to the other end of the pick-up tube for moving the one end of the tube between a first position disposed at a transfer location whereat the one end is exposed to the stones within the supply reservoir, and a second position outside the reservoir whereat the one end is positioned exactly within the field of view of an objective of the microscope such that a stone held adjacent the first opening is disposed precisely at the focal length of the microscope objective.Type: GrantFiled: March 31, 1981Date of Patent: April 12, 1983Assignee: RCA CorporationInventor: Douglas H.

Patent number: 4221297Abstract: An electronic fruit grading machine includes an endless chain having positioning rollers or bars which rotate and on which the fruit coming from a hopper is positioned in rows. The grading machine includes an electronic apparatus capable of detecting surface marks or defects in the fruit which is situated on the bars. The fruit is arranged in transverse rows and is displaced at a certain speed under a standard television camera. The feed of the fruit from the hopper to the endless chain is carried out by a cylindrical drum acting as a feeding device. On the surface of the cylindrical drum are rows of holes, and adjacent each hole is provided a wedge, one face of which follows the prolongation of a radius of the cylindrical drum and is arranged for the expulsion of extra fruit adhered to the periphery of the cylindrical drum.Type: GrantFiled: May 2, 1978Date of Patent: September 9, 1980Inventors: Jose M. Aranda Lopez, Jose R. Conde Hinojosa, Juan Ramos Martos

Patent number: 4195735Abstract: A sorting device, particularly for trout and fish eggs which is of the type having an inclined wall against which the eggs are launched and caused to rebound a distance apart depending on the resilience thereof. Collecting means are provided for receiving the eggs according to their different trajectories. The device comprises a tank for receiving eggs and water having a rotating drum associated therewith having a plurality of cups on the outer surface thereof. Each cup is adapted to receive one egg therein and the cups are arranged in parallel transverse rows. The bottom of the cups is perforated so as to permit the water to be discharged therefrom. A fan is provided in order to dry the eggs in the cups through the perforated bottom thereof and a pneumatic launching device serves to launch the eggs against the inclined wall.Type: GrantFiled: July 18, 1978Date of Patent: April 1, 1980Inventor: Adriano Facchinelli

Patent number: 4154672Abstract: Standardization is provided to control system gain of a penetrating radiation testing system by periodically inspecting a reference object in the same manner as the product samples so as to generate a stabilization signal which is compared to a reference signal. The difference, if any, between the stabilization signal and the reference signal is integrated and the integrated signal is used to correct the gain of the system.Type: GrantFiled: April 28, 1977Date of Patent: May 15, 1979Assignee: Bedford Engineering Corp.Inventors: Philip A. Wiley, Herbert L. Aronson
