  • Publication number: 20240084181
    Abstract: A refrigerant composition includes R1225ye(E) refrigerant, a second refrigerant that is one of R1234ze(E) refrigerant and R32 refrigerant, and a third refrigerant that is one of R227ea refrigerant, R125 refrigerant, and R1234yf refrigerant. The refrigerant composition has a GWP of at or less than about 2000. A method of making a refrigerant composition includes mixing at least an amount of R1225ye(E) refrigerant, an amount of a second refrigerant, and an amount of a third refrigerant to obtain a refrigerant composition that has a GWP of at or about or less than 2000. A method of retrofitting a refrigerant composition in an HVACR system includes adding an amount of at least one refrigerant to a refrigerant composition to produce a retrofit refrigerant composition that includes R1225ye(E) refrigerant, a second refrigerant, and a third refrigerant.

  • Patent number: 10820733
    Abstract: A delivery compartment comprising one or more cavities and one or more doors, such that access to each of the cavities is granted separately. The delivery compartment may include a lock preventing access to the one or more cavities unless authorization is obtained. The delivery compartment may be integrated into a wall, or other structure, associated with a building, such as a residential home or business. The delivery compartment may be built into or otherwise configured into a door for the building such that certain panels allow access to the one or more cavities for delivery of goods while other panels allow access to an interior space of the building itself. The delivery compartment may include environmental control capabilities for one or more of its cavities.

  • Publication number: 20060024656
    Abstract: The present invention relates to a method for making bone particles from bone of a variety of sizes and a workpiece forming and holding device for use with the method. The workpiece forming device includes a base and a base frame attached to the surface of the base. An apparatus for forming a solidified mass of bone and immobilization medium is also provided which includes the workpiece forming device and a detachable former member enclosing the base frame. Bone is immersed in an immobilization medium within such workpiece forming device, which is solidified to form a solidified mass of bone and immobilization medium and then subdivided to provide particles of bone in association to with immobilization medium. The immobilization medium may be optionally removed to leave bone particles suitable for use in orthopedic applications including implants.
