Abstract: Methods for constructing multi-walled carbon nanotube (MWCNT) antenna arrays, may include: variable doping of the MWCNTs, forming light pipes with layers of variable dielectric glass, forming geometric diodes on full-wave rectified devices that propagate both electrons and holes, using clear conductive ground plans to form windows that can control a building's internal temperature, and generating multiple lithographic patterns with a single mask.

Abstract: A tray for a vaporization vessel that includes a tray having a side wall, a bottom plate, one or more apertures that extend through the bottom plate, and a duct that extends through and from the bottom plate. The tray configured to support a solid reagent to be vaporized. A method of assembling the tray that includes forming a first tray that has the side wall and the bottom plate. A vaporization vessel that includes one or more of the trays.

Abstract: A convertible walking/riding power driven golf cart includes three detachable units; namely, a drive unit having a frame supported on wheels connected to a battery operated motor; a steering and golf bag support unit connected detachably to the drive unit and having releasable golf bag connectors and a handle bar mounting a speed control and a brake control; and a riding unit having a wheel-supported platform connected detachably to the drive unit for adjustment between an operative position extending horizontally rearward from the drive unit for supporting a person on the platform for riding, and a storage position disposed vertically closely adjacent the drive unit to allow a person to walk behind the drive unit while grasping the handle bar. The three units are quickly and easily detached from each other for storage and transport in the trunk of an automobile.

Abstract: Method and apparatus is set forth for forming a laminated gob or charge of molten glass having a core glass which is not only completely surrounded by a skin glass but also has a reentrant portion of skin glass which projects inwardly within the core glass from the periphery of the molten charge intermediate its upper and lower extent. The reentrant portion of skin glass is formed within the charge during the gobbing cycle by momentarily retarding or retracting the outward flow of the core glass while simultaneously positively pulsing the flow of the skin glass. Thus, a laminated gob or charge of molten glass is formed which not only has a skin glass completely surrounding and encompassing a core glass but also has a reentrant portion of the skin glass which is continuous with the remainder of the skin glass surrounding the core glass.
