Abstract: Refractory anchoring devices include a main body and a mounting feature for mounting to a thermal vessel. The main body includes four anchor branch segments angled with respect to each other to form an X shape with four unenclosed cell openings, including two opposite triangular side openings and two opposite triangular end openings. In some embodiments, the main body further includes extension segments extending from and angled relative to respective branch segments to define two of the opposite openings as semi-hexagonal. Some embodiments include reinforcement segments extending from branch segments into openings, voids extending through branch segments, two anchor strips inter-engaged to form the four branch segments, and/or a single stud-welding stud for the mounting feature.

Abstract: A window safety plate includes a window-mounted frame, a bullet resistant plate, and a locking mechanism. The window mounted frame includes an upper track, a lower track, a first stopper, and a second stopper. The upper track and the lower track are terminally connected to the first stopper. The upper track and the lower track are terminally connected to the second stopper, opposite of the first stopper. The bullet resistant plate is slidably engaged within the upper track, the lower track, the first stopper, and the second stopper so that a window section of a door can be concealed from inside of a room. The locking mechanism is integrated in between the window-mounted frame and the bullet resistant plate thus enabling an intruder to slide back the bullet resistant plate from outside of the room.

Abstract: Embodiments described herein provide for a compartment based inlet barrier for foreign object debris to an auxiliary power unit of an aircraft or watercraft. The apparatus is configured to fit within an inlet compartment of an auxiliary power unit and provides a particulate separator for fluid flow to the auxiliary power units using a porous pleated filter media having a corrosion resistant exterior frame and enables a minimal pressure differential throughout the apparatus while in use. The apparatus may further be releasably secured/unsecured using a plurality of fasteners which enable a user to readily assemble and disassemble.

Abstract: A door security device and method for its use. The device includes a winch assembly disposed on a support bracket and with a cover that can be applied to enclose and secure the winch assembly. The device is mounted adjacent a door to be secured. The winch assembly includes a tether, a release lever, and a handle. The release lever provides a one-way ratcheting mechanism to restrict extension of the tether and is operable to release the tether. The handle is operable to retract the tether. A door loop installed on the door provides a secure feature for coupling with the tether. The handle and other safety implements may be stored within the cover. The device is deployable by coupling the tether to the door loop to secure a door against opening even when a door handle or lock on the door have been defeated.

Abstract: A method and apparatus that allows a user to preview live audio and/or video of a channel displayed in a multiple channel selection display prior to making a complete selection is generally accomplished by providing pixel information for displaying visual representations of a plurality of channels where the video representation of each channel is displayed in a corresponding channel display area (i.e., a video thumbnail). When the user selects one of the video representations in a preview mode, the video thumbnail is switched from a still image with no audio to an image that includes live audio and/or video. This preview mode remains until the user deselects the preview mode, selects full display area viewing, or a time-out period expires. In addition to the preview option, the user is provided with an editing option that allows the user to customize his or her multiple channel display.
