Latest Patents

Pikus's latest patents include an improved inlead construction for electric lamps. This invention utilizes an iron alloy containing sufficient silicon to prevent the transformation of the inlead from the alpha ferrite phase to the gamma austenite phase at lamp operation temperatures. This advancement helps avoid debilitating deformation of the inlead wires caused by on-off cycling of the lamp. Such deformation can lead to structural or operational failure if the inleads become disconnected or electrically shorted from the resistive filament during lamp operation. In a preferred lamp construction, a pair of the improved inlead wires serves as the sole means of physical support for a resistive incandescent filament directly connected to them. Additionally, these inlead wires can be coated with a dissimilar metal to meet higher lamp loading requirements and to help prevent iron migration, which can deteriorate the resistive incandescent filament.

Another significant patent by Pikus describes an electric lamp construction featuring a pair of conductive inlead wires made of dispersion-strengthened copper alloy. These wires serve as the sole means of physical support for a resistive incandescent filament electrically connected to them. The metallurgical surface of the inlead wires enhances bonding with other materials, including metals such as nickel and aluminum, as well as nonmetallic gettering materials like phosphorous compounds.
