  • Patent number: 10465996
    Abstract: A heat exchanger assembly having a manifold, a partition member inserted into the interior cavity of the manifold through an open end such that the partition member cooperates with the interior surface of the manifold to partition the interior cavity into a manifold chamber and a distributor/collector chamber. The partition member and distributor/collector chamber function together as a distributor/collector tube within the manifold. The partition member includes a plurality of orifices along a length of the partition member, two opposite facing flange portions along the length of the partition member, a bulkhead panel extending from an end of the partition member adjacent the open end of the manifold, and a spring locator tab panel extending from an end of the partition member opposite of the bulk head panel, wherein the spring locator tab panel is biased against the closed end.

  • Patent number: 9879923
    Abstract: A face plumbing adapter having a block portion and a camber portion is provided for a manifold of a heat exchanger assembly. The block portion includes an external planar face, a first mating surface opposite that of the planar face, and an aperture having a B-axis extending through the planar face and first mating surface. The camber portion extends integrally from the block portion in a direction away from the planar face and curving inward toward the B-Axis. The camber portion is biased toward the block portion such that the face plumbing adapter would clinch onto the manifold. The block and camber portions include respective mating surfaces that are complementary to the exterior surface area of the manifold onto which the mating surfaces are affixed.

  • Patent number: 8882155
    Abstract: An assembly for fastening a fitting to a hole in a tubular manifold having a hole. A plurality of refrigerant tubes extend into the manifold transversely to the hole. The assembly includes a fitting that extends along an axis and defines an opening to provide clearance for the refrigerant tubes extending into the manifold. The fitting also presents a pair of slots in spaced and parallel relationship with one another. The assembly further includes a semi-cylindrical shaped mounting plate including a bracket. The bracket presents a pair of legs which extend in spaced and parallel relationship with one another and engage the slots of the fitting to limit rotary movement of the fitting about the axis relative to the bracket before and during brazing of the fitting to the manifold to maintain a clearance between the lower section of the fitting and the refrigerant tubes.

  • Patent number: 8668558
    Abstract: A cutting tool is provided for safely dressing a game animal having a handle and a fork section including first and second elongated shielding members shielding the hunter's hands and a cutting blade positioned between the first and second elongated shielding members and perpendicular relative to a longitudinal axis extending along the length of the cutting tool and wherein the handle is configured in a T-shaped manner for providing a good grip and wherein the cutting blade is positioned under outer surfaces of the first and second elongated shielding members to further shield the hunter's hands. The cutting tool is pushed against various membranes and the trachea to safely cut it for the removal of the heart and lungs of the game animal.

  • Patent number: 8128128
    Abstract: A coupling of a heat exchanger includes a saddle for engaging a cylindrical manifold. The saddle has an arcuate cross-section extending between a first edge and a second edge. The saddle defines an opening and a tubular member extends through the saddle and between a top edge and a bottom edge. A lip extends outward from the top edge and a skirt interconnects the lip to the opening in the saddle. The tubular member is oblong-shaped adjacent the opening of the saddle and the tubular member has an oblong-shaped portion extending from the bottom edge to adjacent the opening in the saddle and terminating at a transition zone. The tubular member has a circular-shaped portion extending from the transition zone to the top edge. The oblong-shaped portion has a shorter dimension in the direction between the first and second edges than the circular shaped portion.

  • Patent number: 7921558
    Abstract: A heat exchanger assembly includes an outlet header extending along an outlet axis to define an outlet cavity and an inlet header defining an inlet cavity. A plurality of refrigerant tubes extends from the inlet header through the outlet header and into the outlet cavity. A collector conduit having a generally semi-circular conduit cross-section defining an arced surface and a chord surface interconnected with rounded ends is disposed in the outlet header and includes a conduit body portion and at least one conduit end portion interconnected by a conduit transition portion with the conduit body portion being offset from the conduit end portion. The conduit body portion is engaged to an interior surface of the outlet header to space the conduit body portion from the refrigerant tubes and the conduit end portion is coaxial with the outlet header axis to provide a central outlet for the refrigerant vapor.

  • Patent number: 7874235
    Abstract: The right handed hunter uses a special safety tool having a pistol grip handle firmly gripped by the hunter's left hand and having a slot formed in a forward portion of the safety tool for receiving a knife blade with its cutting blade up during dressing of the game. With the right hand of the hunter gripping the knife handle and holding the knife blade within the slot, he pushing the safety tool forward with his left hand while pushing the knife forward with his right hand to form an elongated cut in the game. This arrangement ensures that both hands are safely kept well away from the cutting edge of the knife blade while forming the elongated cut. The slot is a deep one, formed in the forward portion of the safety tool, enabling the tool to receive types of widely used knife blades of any shape.
