Abstract: A house number plate and lamp assembly includes a housing having an opening; a window plate fastened inside the housing behind the opening and having a plurality of view windows; a plurality of number plates fastened to either view window, each number plate having a plurality of small through holes made around the border of a white-colored numeral being printed on a black-colored front surface thereof, a holder frame on a back surface thereof, a light emitting device mounted on the holder frame at the top, a plurality of optical fiber tubes fastened to the holder frame at the bottom and respectively inserted in either small through hole; and an electric circuit board fastened inside the housing and controlled to provide power supply to the light emitting device on each number plate causing it to send light through the optical fiber tubes in illuminating the numeral.

Abstract: A method and apparatus for forming a setting for an article such as a gemstone, and the setting formed, use a sheet metal support member defining channel-like ends that bear against ends of the article. The method includes folding a length of sheet material along an axis to form a support member defining a channel, compressing a central part of the channel while leaving the ends open thereby forming holding channels connected by to form a central web, and affixing a prong member to the web portion of the channel by soldering. The web portion of the channel is notched for receiving the prong member and bent transverse to its fold to bring the channel-shaped opposite ends of the support member into opposition. Support members can be produced to cover a range of gem sizes by trimming and notching the support member of one range size as required to fit a certain gem size in the range. The notching step is aligned such that the support member when bent defines a rectilinear notch for the prong member.
