| 20080202427 | Automated egg injection machine and method - A pneumatically operated egg injection machine includes a sealed frame structure with a pair of in line parallel tracks through an injection section and a transfer section in series. An injection assembly includes a plurality of injectors gripped in a support plate to simultaneously inject vaccine into the same injection region irrespective of egg height and orientation. Fluid delivery systems meter prescribed vaccine dosages to the injecting needles with reduced turbulence, friction, heat and residence time to increase the delivered titer to the injected eggs. A transfer assembly lifts the injected eggs by causing a reduced pressure around the injection hole while maintaining the injection hole at atmospheric pressure. The injection assembly is sprayed with a sanitizing solution at the same time that the injected eggs are moved from the injection section to the transfer section. | 08-28-2008 |

| 20090126636 | Combined punch and needle for automated egg injection machines - An improved needle design is cut diagonally from two sides to form a sharpened cutting edge, rather than a point. The needle has an external diameter and wall thickness sufficient to provide the rigidity necessary to punch the egg shell while the sharpened edge provides a sharp cutting edge able to sever the underlying membrane cleanly and penetrate an embryo if necessary. The needle's penetrating edge design prevents needle tip fold-over and the resulting formation of a hook which can lead to cross-contamination of eggs and shortened needle life. | 05-21-2009 |
| 20090183685 | In-ovo injection machine with transversely movable egg tray assembly for manual egg transfer after injection - An in-ovo egg injection machine has a transversely or laterally movable supporting structure which is mounted beneath and adjacent the injector assembly and enables the operator to move egg trays into and out of the injection area from the side of the machine. The supporting structure includes two longitudinally extending opposed support rails that are mounted on a movable member so that the longitudinal support rails are spaced from one another at a set distance to define a support cradle. The movable member is supported on two transversely extending guide rails that are approximately twice the width of the injection area in length so as to allow the support cradle to be moved, preferably by hand, to an injection position directly under the injector assembly and then, by moving the support cradle in a lateral direction on the guide rails, to a loading/unloading position horizontally spaced from the injection area. | 07-23-2009 |
| 20110061601 | Method and apparatus for reduction of ammonia, carbon dioxide and pathogens in chicken houses - A chicken or fowl grow out facility utilizes a ventilated floor assembly including a ventilated floor through which liquid and gas can flow, but which retains manure and other solids deposited thereon, and a bottom floor plenum underneath the ventilated floor. A liquid and vapor barrier sheet preferably covers the ground surface underneath the floor assembly which together insulate the high temperature of the grow-out facility from the heat sink effect of the lower temperature ground. Conventional tunnel ventilation of the chicken house through the ends of the house creates a negative pressure inside the house relative to the outside environment which is vented to the floor assembly plenum. As a result of this tunnel ventilation and negative pressure, moisture in the manure from urine and otherwise evaporates into the air in the growth chamber and floor assembly plenum to effectively keep dry the manure retained on the floor and reduce ammonia formation and pathogen growth. | 03-17-2011 |
| 20110067633 | VIBRATION MECHANISM FOR VERTICAL EGG ALIGNMENT PRIOR TO IN-OVO INJECTION - An in-ovo egg injection machine generates and transmits vibration to an incubating egg tray to align the egg axes prior to injection. The mechanism can be used independently of the in-ovo egg injection machine and is suitable for use with an egg candling machine. With the eggs positioned on the incubating tray and held by egg tray posts with their large ends facing upward for the purposes of incubation, vibration is applied to the tray. The vibration allows the eggs to ‘float’ in their restricted locations in the egg tray. Since the eggs are naturally bottom-heavy, the heaviest portion of each egg moves down as the tray is vibrated. The eggs therefore self-align their axes into an orientation corresponding with the established vertical axes of the injectors, respectively, with no contact with the eggs being required. | 03-24-2011 |
