Abstract: A molding assembly includes lower and upper molds. The lower mold includes an elongated mold cavity, and two spaced apart lower core positioning posts. Each of the lower core positioning post has a lower abutment end face. The upper mold includes an elongated mold cavity, and two spaced apart upper core positioning posts. Each of the upper core positioning posts has an upper abutment end face abutting against the lower abutment end face of a respective lower core positioning post when the lower and upper molds are closed. Each of the upper and lower core positioning posts is spaced apart from a confining wall of the mold cavity of a corresponding one of the upper and lower molds so that a gap is formed around each of the upper and lower core positioning posts and between each of the upper and lower core positioning posts and the confining wall.

Abstract: A mounting device is to be secured to a bottom side of a connecting end portion of a fan blade of a ceiling fan. The mounting device includes a decorative member and a mounting arm having a plate-like blade mounting end portion which is to be disposed horizontally beneath the connecting end portion of the fan blade and which is formed with an insert hole that complements the decorative member for retaining the decorative member thereon, and a plurality of screw sockets that are disposed around the insert hole. Screw fasteners extend through the connecting end portion of the fan blade to engage the screw sockets and retain the mounting arm on the fan blade.

Abstract: A decorative lamp assembly includes an enclosure body having a cover portion and an electric bulb unit fixed in the enclosure body. A bowl-shaped transparent rotary member is mounted rotatably in the enclosure body and is located between the bulb unit and the cover portion. A pattern unit is indicated on the rotary member. A plurality of transparent rotary disks are formed with pattern units and are mounted rotatably within the rotary member between the bulb unit and the cover portion so that rays of light emitted from the bulb unit pass through the rotary disks and the rotary member and penetrate partially the cover portion to display silhouettes of the pattern units of the rotary disks and the rotary member on the external surface of the cover portion. A driving unit rotates the rotary disks and the rotary member.
