Abstract: A lens assembly especially adapted for mounting in an environment subject to variable temperatures, such as a projection television set, including an automatic thermal focus adjustment. A lens mount is formed from a material having a first coefficient of thermal expansion and carries at least one lens. A focus mount is coupled to the lens mount and is formed from a material having a second coefficient of thermal expansion different from the first coefficient of thermal expansion. Adjustment and locking structure couples the lens mount to the focus mount and allows the lens mount to be axially adjusted relative to the focus mount and then locked in position. In use, the relative axial positions of the lens mount and focus mount automatically change to move the lens in response to a temperature change in the environment of use and after being locked in position with the adjustment and locking structure.

Abstract: Process and apparatus for assembly of an ecologically compact disc or media package where a trayed rotating table advances to process a packaging sleeve and place a compact disc or media package on a processed packaging sleeve. A packaging sleeve is placed in a tray on one rotating table and subsequently a pamphlet is glued to the packaging sleeve. A one-piece compact disc or media base on another rotating table is placed on the awaiting packaging sleeve. An end cap can then be separated from the base. The packaging sleeve is secured by glue to the compact disc or media base and end cap. The end cap is either cut away or manually separated from the media base.

Abstract: Fully automated apparatus and method for manufacturing compact disc holders having a central rotating table about which conveyor tables, rotary tables, placers and other devices align to interdigitate and load compact discs into disc bases, to mate disc bases containing CDs to packaging sleeves, to load booklets into the packaging sleeves, and to handle, glue, fold and otherwise form a package containing CDs and booklets or literature.
