Latest Patents

Smith's latest patents include a solid-state detonator and a method for making glass-to-metal seals. The solid-state detonator utilizes a silicon chip designed to provide the necessary resistance path for detonating primary explosives. This innovative design incorporates a metal-to-glass-to-metal header, ensuring uniform current flow and insulation capabilities. Additionally, a gold mesh conductor connected to a chromium-silicon resistor film creates a uniform heating ring for effective detonation. The silicon chip can be doped for enhanced conductivity and low resistance, allowing for rapid function with moderate power pulses while maintaining high no-fire current levels.

The second patent focuses on a method of creating a glass-to-metal seal. This process involves a chemical bond between the glass and metal, achieved through an oxide layer that joins the two materials. A glass tube or powder with a coefficient of expansion similar to that of the metal is used, and the components are heated in a controlled dry hydrogen atmosphere to establish a strong bond.
