Latest Patents

One of Lunde's notable inventions is the Auger Quick Coupler. This device is designed to secure an auger and/or extension pieces to a PTO shaft. In one construction, a threaded PTO collar mounts to a PTO shaft and mates with a suitable length stub shaft and a captured, knurled hand nut mounted to an auger. The stub shaft indexes in non-rotational engagement to the PTO collar. In another construction, a PTO collar provides several detents that interconnect with resiliently biased projections at an auger collar. A hand piece maintains the connection. Additionally, key(s) at the PTO shaft mate in non-rotational engagement with keyway(s) at an auger, and a resilient member latches the non-rotational connection. Shaped PTO shaft surfaces and complementary auger coupler surfaces can be included with the later couplers to enhance the connection.

Lunde's second patent is for a low-cost process for the manufacture of hurricane-resistant, impact-resistant glass units. This innovation utilizes liquid laminating resin systems to impart hurricane-resistant properties to insulated glass window units. The activated resin system can be deposited on a single piece of float glass with the containment insulating unit, or it can be injected between the air space of an existing insulated unit. In both cases, the resin is allowed to cure for 3 to 4 hours. The finished insulated and impact-resistant glass unit can then be installed into the window frame structure. Preferred resins include multiple component polyurethanes and special low shrinkage polyester systems with Argon gas between the glass layers after the resin has cured.
