    Abstract: A liquid photopolymer layer covering a phototool image surface with one surface exposed to air is exposed by radiation through the phototool to partially harden in a pattern defined by the image the photopolymer layer through a part of its thickness. The air exposed surface portion is thus left in liquid form for contacting the surface of a printed wiring board, preferably by scanning along the length of a phototool with a pressurized roll or blade to contact and adhere the preimaged laminate to board surface in an air bubble free lamination where subsequent radiation exposure finishes the curing and bonds the cured portion of the polymer layer to the PWB substrate. After removal of the phototool, the polymer layer is developed by washing out uncured polymer portions as defined by the image pattern.

    Abstract: An electrical connector includes a housing composed of two hinged-together housing sections molded of plastic as a single unitary part. One housing section defines a pair of spaced-apart resilient walls with a slot between them and a series of connector locations spaced along the slot. The other housing section defines a series of compartments which are in register with the connector locations when the two housing sections are superimposed. A flexible printed circuit is folded into the slot, the circuit having pairs of conductive paths positioned in the slot at each said connector location, which paths extend out of the slot so that electrical connections can be made to provide electrical power to bulbs removably retained at said connector locations and in electrical contact with the path pairs at said locations. The front wall of the housing cover section constitutes a light transmitting lens so that, when a bulb in a given compartment is energized, it illuminates that compartment to the exclusion of the others so as to make visible only the legend inscribed on the lens in register with that compartment.
