Abstract: The disclosure relates to obstacle array devices (also known as bump array devices) for separating populations of particles by size. Improvements over previous obstacle array devices are realized by causing the fluid velocity profile across gaps between obstacles to be asymmetrical with respect to the plane that bisects the gap and is parallel to the direction of bulk fluid flow. Such asymmetry can be achieved by selecting the shape(s) of the obstacles bounding the gap such that the portions of the obstacles upstream from, downstream from or bridging the narrowest portion of the gap are asymmetrical with respect to that plane. Improvements are also realized by using obstacles that have sharp edges bounding the gaps. Other improvements are realized by selecting obstacle shapes such that the critical particle dimensions defined by the gaps in two different fluid flow directions differ.

Abstract: This invention is directed to a device for separating deformed balls from normal spherical balls prior to washing as is common in the ball pen industry. The device comprises an L-shaped tunnel which defines a slot on its lower surface. The slot feeds into a receptacle positioned below the tunnel. Balls enter under the force of vacuum pressure through an intake opening, striking a first bi-angled deflector plate. Deformed balls will fall through the slot into the receptacle in most cases. However, to increase the likelihood of such an eventuality, the balls then strike a second deflector plate and are sent down the second leg of the L-shaped tunnel. The second leg also defines a slot. By striking the second deflector plate, the ball is reoriented and the likelihood of passing through the slot is increased. Thus, normal balls are left and pass from the L-shaped tunnel out through an output opening and on for conventional washing.

Abstract: An apparatus for the grading of fish into various size categories, utilizing a series of panels with progressively smaller spaces between grading bars on the panels. The panels are attached to a panel box that may be raised or lowered within a holding vat. Water constantly flows through the holding vat, up through the panel box, and out over a spillway at the top front of the holding vat. By raising the panel box, the largest fish are forced out of the holding vat and down the spillway by the grading bars on the panels inside the panel box. Smaller fish swim through the grading bars on the panels with wider spaces between grading bars, and are not forced out of the holding vat until a lower panel with narrower spaces between grading bars is raised to the edge of the spillway. The constant flow of water up and toward the spillway causes the fish to instinctively swim downward and align themselves parallel to the grading bars and keeps the fish oxygenated during the grading process.

Abstract: Worms are harvested by placing worm-containing bedding material from a breeding bin on a flat breaking board mounted within a wooden frame. The bedding material is pushed from the board onto an adjacent screen mounted within the frame at approximately the same level as the board. The screen is covered by the bedding material to a uniform depth while exposed from above to light. A worm-receiving tray with dark inner bottom surface is removably mounted in darkness within the frame below the screen. The frame is leg-supported at one end, while its screen-end rests on the top edge of a bin to be harvested. An upper layer of the bedding material is gradually skimmed from the screen into the bin, causing the worms to work their way deeper into the bedding material remaining on the screen. The skimming process is repeated until all worms have worked their way down through the bedding material to the screen. From there the larger worms crawl through the screen into the tray below.
