Patent number: 9091623Abstract: A system for determining the characteristics of a volume of preferable small fungible products within an acceptable size range. The system differentiates among products even if in close contact to identify acceptable product. The system may store data for later review or for dispensing of product in real time. The system may include a scale to determine a sample's weight, a camera to image the sample, an imaging table to permit viewing of the sample, a processor to determine the number of products in the sample, and a processor to determine the density of desired product. The system may also determine product count-per-weight, product volume-per-weight, and/or product surface-area-per-weight. These determinations may be useful, including in determining product processing and packaging options.Type: GrantFiled: February 5, 2014Date of Patent: July 28, 2015Assignee: Satake USA, Inc.Inventors: William Keith Beaty, Patric Carey Pike, Calvin G.

Publication number: 20110008629Abstract: A laminated panel comprises at least one facer comprising a coating applied to a facer sheet to provide a coated facer surface, and a thermosetting plastic foam firmly adhered to the coated facer surface. In an example, non-limiting embodiment, the facer sheet comprises a nonwoven glass mat; the coating comprises a coating mixture comprising a mineral pigment and a dried latex; and the thermosetting plastic foam is comprised of an insulation material selected from the group consisting of polyurethane modified polyisocyanurate foam, polyurethane foam, and phenolic-formaldehyde foam. In an example variation, the nonwoven glass mat has the coating applied to two opposing flat surfaces thereof.Type: ApplicationFiled: August 11, 2008Publication date: January 13, 2011Applicant: Atlas Roofing CorporationInventors: Daniel D.

Patent number: 5845784Abstract: A multiple channel gravity-fed slide for a sorting machine is disclosed wherein the heights of the divider ribs between channels are at least high enough to define the channels and keep normally sized products flowing within the respective channels. At least some of the dividers or ribs have a tall height for supporting a product guide or keeper to provide some singulation and order to the products in the respective channels while allowing oversized and misshapen items to overlap into adjacent channels, thereby minimizing jamming of one or more channels.Type: GrantFiled: October 25, 1996Date of Patent: December 8, 1998Assignee: Satake USA Inc.Inventors: Calvin G. Gray, Dale A Svatek

Patent number: 5631460Abstract: A photo-optical detector for use in a multi-chromatic sorting machine, each detector including at least two separate photodiode materials responsive to a different spectral range and a multi-peak optical filter having transmission response characteristics that are respectively defined in a frequency spectrum of the respective spectral ranges of the materials. The sorting machine using such detectors can be selectively programmed using the various resulting signals from the detectors after appropriate amplification and threshold detection to cause resulting ejection mechanism activation.Type: GrantFiled: April 4, 1996Date of Patent: May 20, 1997Assignee: Satake USA Inc.Inventors: Calvin G.

Patent number: 5407082Abstract: In a bichromatic sorting machine, a polygon pattern of trip level boundaries is established for a master channel programmable memory that is representative of orthogonally plotting detected products in each of two reflectivity spectral bands. The rate of products passing through the master channel that is rejected as being non-acceptable by producing a reflectivity value outside of the polygon pattern compared to total products sorted is used as the basis for normalizing all channel results. When the actual rate in the master channel varies from the desired rate, the boundaries of its polygon are concentrically adjusted back to the desired rate, thereby also adjusting the similar polygon patterns for each of the other or slave channels. Multiple machines can also be normalized to the same rate in similar fashion. The master channel or the master machine can be selectable, a concept that is also applicable to monochromatic sorting machines, as well.Type: GrantFiled: July 28, 1994Date of Patent: April 18, 1995Assignee: ESM International Inc.Inventors: Joel P. Childress, Edward G. Reyes, Calvin G. Gray

Patent number: 5402264Abstract: An optical inspection system (10) has an inspection region (20) through which articles (12) pass and are illuminated by illumination (22) provided by an illumination source (30). The source is shielded from the inspection region by a protective shield or tube (32) transmissive of the illumination. A cleaning element (42), such as a plastic string, contacts a major surface (45) of the tube and dislodges contaminants (63) from the major surface as the tube rotates. The cleaning element has an active portion (60) held in contact with the major surface by tension in the cleaning element applied at tension locations (56, 58). The cleaning element describes part of a spiral or helix; it preferably occupies less than about 360 degrees, more preferably between about 30 and about 270 degrees, and still more preferably about 120 to about 240 degrees, of arc measured about the axis of the tube.Type: GrantFiled: July 28, 1993Date of Patent: March 28, 1995Assignee: Simco/Ramic CorporationInventors: John H. Wilbur, Calvin G. Gray

Patent number: 5339964Abstract: A passively vented rejected article chute (40) includes at least two vents (44, 45) extending downwardly into the chute to vent air in directions (50) safely away from sorting and conveying functions, thereby improving sorting effectiveness. Rejected articles (14) that include defects (24) are deflected by an air ejector module (30) into the vented chute and are directed downwardly past the vents to preventing the vents from being blocked. The vents, formed by panels (46, 48), are flared open at their outer ends (54, 56) to decrease the velocity of exhaust air as it passes upwardly through them. Reducing the exhaust air velocity allows small and/or light weight articles entrained in the exhaust air to fall back into the reject chute, thereby preventing spillage of the entrained articles.Type: GrantFiled: September 20, 1993Date of Patent: August 23, 1994Assignee: SIMCO/Ramic CorporationInventors: Calvin G. Gray, Frank B. Thomason
