Abstract: A folding stroller having a structural frame formed of a plurality of rigid support members. The stroller is provided with a skirt formed of a flexible material. The skirt can be disposed around at least a portion of an outer perimeter of the stroller to create a visual impression of something other than an ordinary stroller. For example, the skirt can create a visual impression of a vehicle such as an automobile, truck, airplane, spacecraft, an animal or a character. The skirt can be formed of fabric, plastic sheeting or film, or a mesh. A suspension frame is provided for suspending the skirt along a least a portion of an upper edge thereof. The suspension frame can at least partially define a profile of the vehicle, animal or character. The suspension frame folds with the structural frame of the stroller for ease of storage.

Abstract: Illuminated display case for collectibles that can simulate the look and feel of a collectible's theme. The display case can be modular in design, such that one case can serve as the basis for the joining of additional case modules to form a larger illuminated display. Through the use of a specialized alignment structure, display cases can be lined up one next to the other to form a continuous track around a room.

Abstract: A heat exchanger fin collar for a plate-fin heat exchanger having close tolerance dimensions for achieving greater contact area on the tube. The fin collar comprises an elongated fin portion for dissipating heat and a leg connected with the fin portion. The leg has a height and includes a straight contact portion substantially perpendicular to the fin portion, wherein the contact portion has a contact height along which the contact portion contacts the tube. The height is in the range of 0.008 to 0.080 inches. It also includes a first curved end portion having a first radius extending from a first end of the contact portion and a stepped transitional portion connecting the contact portion and the elongated fin portion. The transitional portion has a second curved end portion having a second radius, wherein the second curved end portion extends from the contact portion opposite the first end. A method for forming the fin collar and a heat exchanger are also disclosed.

Abstract: A plate fin heat exchanger is made such that the distance between the trailing edge of its plate fins and the nearest row of tube openings is substantially greater than the distance between the leading edge and its tube openings, thereby reducing the occurrence of condensate carry-over into the airflow stream.
