  • Patent number: 7699119
    Abstract: A coupler for securing an auger and/or extension piece(s) 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 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. In other embodiments, 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.

  • Patent number: 7204901
    Abstract: Liquid laminating resin systems are used to attribute hurricane resistant properties to insulated glass window units. The activated resin system is then deposited on a single piece of float glass with the containment insulating unit or the resin can be injected between the air space of an existing insulated unit. In the first case, the second piece of glass completes the insulating unit. In both cases, the resin is allowed to cure 3–4 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.
