Endless Conveyor Patents (Class 356/58)
-
Publication number: 20100026989Abstract: A conveying device for conveying eggs comprises an endless conveyor provided with rollers extending transversely to the direction of conveyance. The rollers are arranged in pairs, and each pair of rollers forms an receiving space, in which an egg is accommodated in such a way that the egg rests on both rollers. The conveying device furthermore comprises a transfer device provided with a plurality of pick-up elements for picking up the eggs from a tray and placing the eggs on the conveyor. The pick-up elements on the transfer device can be moved from a first position in which they are positioned at a distance from each other corresponding to the distance between the individual eggs on the tray, viewed in the direction of conveyance, and a second position corresponding to the centre-to-centre distance between two receiving spaces.Type: ApplicationFiled: March 1, 2007Publication date: February 4, 2010Inventors: Erik Jan Wildenbeest, Jan Wilem Pennings, Dirk Willem Wikkerink

Patent number: 7113817Abstract: New devices and methods are provided for noninvasive and noncontact real-time measurements of tissue blood velocity. The invention uses a digital imaging device such as a detector array that allows independent intensity measurements at each pixel to capture images of laser speckle patterns on any surfaces, such as tissue surfaces. The laser speckle is generated by illuminating the surface of interest with an expanded beam from a laser source such as a laser diode or a HeNe laser as long as the detector can detect that particular laser radiation. Digitized speckle images are analyzed using new algorithms for tissue optics and blood optics employing multiple scattering analysis and laser Doppler velocimetry analysis. The resultant two-dimensional images can be displayed on a color monitor and superimposed on images of the tissues.Type: GrantFiled: October 4, 2001Date of Patent: September 26, 2006Assignee: WinTec, LLCInventors: Leonard W. Winchester, Jr., Nee-Yin Chou

Patent number: 7034926Abstract: Methods and apparatus for producing vaccine within a plurality of eggs are provided. Each of a plurality of eggs is illuminated with light from one or more LEDs. A detector is positioned adjacent each egg and detects light passing therethrough. Each egg is then identified as containing a live embryo or as being a non-live egg. Each egg that is determined not to contain a live embryo may be removed, either automatically or by hand. A seed virus is injected into each egg identified as containing a live embryo. After a predetermined period of incubation each live embryo is euthanized and amniotic fluid containing a vaccine produced as a result of the presence of a seed virus is harvested from each euthanized egg.Type: GrantFiled: December 9, 2004Date of Patent: April 25, 2006Assignee: Embrex, Inc.Inventor: John H. Hebrank

Patent number: 6373560Abstract: An apparatus for candling eggs includes a transmission system of a luminous flux directed towards the egg to be examined and located in its incubation rack a reception device of the luminous flux transmitted after passing through the mass of the egg, and an automatic analyzer of the recorded signals. The transmission system and the reception device are arranged in a vertical plane or a substantially vertical plane, one beneath the eggs to be examined and the other above the latter. A screen protects the transmission system against smears originating from the eggs in the incubation racks.Type: GrantFiled: June 16, 1999Date of Patent: April 16, 2002Assignee: ECMASInventor: Roland Roux

Patent number: 5898488Abstract: The apparatus of the present invention provides a means for candling eggs and providing trays of eggs filled with candled eggs and includes a provision wherein infertile eggs are removed from trays of fertile eggs and are replaced with fertile eggs in order to supply a complete array of fertile eggs within the tray. The apparatus includes a conveying means removing trays of eggs from an infeed station to an outfeed station. The trays of eggs supplied at the outfeed station preferably are completely filled with fertile eggs only and usually will be supplied to a processing station such as for inoculation. The apparatus includes four stations with candling performed at the first station by a video camera with infertile eggs moved to an exit hopper at a second station thereadjacent.Type: GrantFiled: January 21, 1997Date of Patent: April 27, 1999Inventor: Jeffrey B. Kuhl

Patent number: 5646722Abstract: An apparatus for candling eggs travelling along a path for the presence of blood, comprising a lightproof drum which is drivable for rotation around a fixed shaft and wherein detection means are accommodated, the drum having a number of light transmission openings which each have a bellows, the drum in operation having a rotational speed so that the ends of the bellows remote from the drum have a speed corresponding to the speed of travel of the eggs, the drum with the bellows being positioned relative to the path of travel so that in operation, each time during a part of the path of travel of the eggs, the bellows connect to an egg to be inspected, while the detection means are positioned in the drum so that they only receive light that falls into the drum via the egg which is to be inspected and to which the bellows connects, and via the light transmission opening associated with that bellows.Type: GrantFiled: November 28, 1995Date of Patent: July 8, 1997Assignee: FPS Food Processing Systems B.V.Inventor: Jelle van der Schoot
