Abstract: Various embodiments of a radiation curable coating compositions are provided. In one embodiment the radiation curable coating composition comprises an epoxidized vegetable oil oligomer made from the reaction of epoxidized vegetable oil (EVO) and at least one of a hydroxyl functional acrylate and a hydroxyl functional methacrylate, in the presence of an acid catalyst.

Abstract: A portable device for swatting and collecting bugs, insects, flies and the like is disclosed herein. In one practicable embodiment, the device includes a spread structure having a designated swatting surface, a handle having an inner hollow defined therein, a hollow tube having an open distal end joined to the spread structure and an open proximal end joined to the handle, an activatable vacuum system in fluid communication with the inner hollow of the handle, an electric power source electrically connected to the vacuum system, and a hold in fluid communication with the inner hollow of the handle. In this configuration, bugs can be struck with the swatting surface of the spread structure by wielding the handle, and air can be drawn into the open distal end of the hollow tube by activating the vacuum system so as to convey the bugs to the hold.

Abstract: In one embodiment, a bridge damage detection system comprises a first conductor and a second conductor suitable for carrying electric current, the first and second conductors suitable for running along a first section of a bridge. The system also comprises a junction box affixed to the first section of the bridge, the junction box coupling a first end of the first conductor and a first end of the second conductor. The system further comprises a control panel coupled to a distal end of the first conductor and a distal end of the second conductor, the control panel being operable to provide an electric current on the first conductor and to monitor the second conductor for an expected return electric current, the control panel being operable to transmit a signal to activate a notification device upon failing to detect the return electric current on the second conductor.

Abstract: An injection gun especially useful for injecting low volume, high pressure shots of bone cement. The gun includes a cylindrical housing with a plunger including a plunger rod extending axially through the housing. The plunger rod includes a segment which is provided with an axial series of notches. A ratchet block is slidable axially within the cylindrical housing and is concentric with the plunger rod. The ratchet cylinder mounts at least a ratchet pawl urged against the plunger rod and adapted to engage and lock into the series of notches for forward movement. A pistol grip extends from the cylindrical housing, and a lever is pivoted thereto with an extension of the lever engaging the ratchet cylinder for advancing the plunger. A second ratchet pawl is mounted on a fixed member of the cylindrical housing for retaining the plunger against rearward movement when the pawl in the ratchet cylinder is disengaged from the rod.
