Latest Patents
One of his latest patents is the "Rockbolt and Installer Wand." This invention features a rockbolt designed for installation in a bore in the roof of an underground excavation. It supports the roof and includes an installer wand for the temporary insertion of hardenable material into the rockbolt. The rockbolt comprises a sleeve with ports near the upper end and means for engaging the installer wand. The installer wand is an elongated member that conducts hardenable binder and connects to a source of binder material. Its head engages the rockbolt to facilitate the binder's flow.
Another notable patent is the "Binder-Injection Rockbolt." This rockbolt is also intended for installation in a bore in the roof of an underground excavation. It consists of a sleeve and a central member that extends along the sleeve's length, creating an annular chamber. The lower end of the sleeve engages a faceplate that secures it to the roof. Ports at the lower end allow for the introduction of separate components of a hardenable binder material, which mix as they travel through the annular chamber. The binder is extruded through ports at the upper end, filling the annular space and hardening to secure the rockbolt in place.
