A unit for converting a bottle or similar receptacle having a neck into a lamp, said unit mounted around the outside of the bottle neck. The basic portion of the unit consists of an inverted cup whose inside diameter exceeds the outside diameter of the bottle neck. The cup carries at least three threaded engaging screws at its lower end. The lower end of a conventional lamp pipe carrying a lamp socket at its upper end, is threaded into the upper central portion of the inverted cup. A self-locking press-plate is threaded at the bottom end of the lamp pipe inside the cup so that the plate rests on top of the bottle neck. At the lower end of the cup, screws engage the bottom end of a shoulder on the bottle neck such that as the lamp pipe is threaded into the cup, the cup and the engaging screws are pulled upwardly thus a compressive force is developed between the shoulder and the top of bottle neck which force holds the unit firmly onto the bottle to complete a lamp. The radially movable screws and axially movable press-plate make a suitable arrangement for accommodating various bottle neck sizes in lengths and outside diameter.
Three metal layer customizable gate array devices and techniques to customize them are disclosed. Such a device incorporates an integrated circuit blank having a plurality of transistors and at least three metal layers. A plurality of fusible links interconnects said plurality of transistors into an inoperable circuit. A laser ablative etch resistant coating is formed over the device. Later, the coating is ablated by laser at locations overlaying designated fuse locations. The device is then etched for selectably removing some of the fusible links, thereby converting the inoperable integrated circuit blank into an operable gate array device.
