  • Patent number: 11964053
    Abstract: Methods and formulations for a simplified, single-injection method to induce and control the synchronous growth (superstimulation), and ovulation (superovulation) of multiple ovarian follicles in bovine, ovine, caprine, camelid and other female animals enabling the subsequent collection of (a) multiple oocytes when conducting in-vitro fertilization, or (b) multiple embryos when conducting multiple ovulation embryo transfer.
    Type: Grant

  • Patent number: 5514119
    Abstract: An improved embryo collection device (10) is provided which minimizes the possibility of embryo damage or loss while facilitating rapid collection, isolation and extraction of embryos from an embryo-containing irrigant fluid. The device (10) includes a vessel (12) including an outlet port (22) for conveying filtered irrigant fluid out of vessel (12), a filter insert (14) positioned within vessel (12) for filtering embryos out of the irrigant fluid, and a lid (16) removably connected to the filter insert (14) including an inlet port (50) for delivering embryo-containing irrigant fluid to the vessel (12). The vessel (12) is formed of light-transmitting translucent or transparent material, and the filter insert (14) preferably includes isolation cells (42) so that the collection device (10) can be directly placed within a microscope for rapid examination and extraction of collected embryos (91).

  • Patent number: 5054542
    Abstract: A heat transfer system for a building and the building's appurtenances utilizes a heat transfer medium that obtains heat from environmental panels. The heat transfer medium flows in a unidirectional mode through the system. The heat transfer medium is passed through heat exchangers where the heat values in the medium are exchanged or transferred to water to raise the temperature of the water which is then subsequently used as hot water for appurtenant building uses. The heat transfer system, independently from the ambient heat obtainable from the environmental panels, can also utilize heat drawn from air conditioning units to both cool the air passing through the air conditioners and to heat the heat transfer medium. This heat is then exchanged or transferred to the various water sources for use in the appurtenant building uses. An electrical control system selectively transfers the available heat values to those appurtenant building uses, giving preference to those uses as determined by the operator.

  • Patent number: 4139073
    Abstract: The transfer gear case for a power dividing transmission is hingedly connected to one frame section of an articulated tractor vehicle and supported for angular displacement about an oscillation axis by the other frame section of the vehicle. The transmission output shaft is rotatably mounted within the transfer gear case about the oscillation axis and is connected by universal drive shafts to the vehicle wheels respectively supporting the two frame sections.
