Abstract: The present invention provides a fixture or device which is particularly adapted for installation within a confined compartment of an aircraft, such as a lavatory, galley or cockpit, and which emits UVC within safe limits, i.e., within prescribed safe wavelengths, irradiance, and times (below the ‘Actinic Dose’) while the compartment is occupied, to continuously disinfect the interior air and prevent transmission of not only viruses, but pathogens and the like. The device is preferably a triangular prism which houses a metal core pcBoard, a controller pcBoard and at least one support frame which are fabricated from a heat dissipating metal, as is the hypotenuse of the prism.

Abstract: The present invention provides a method for altering the bead profile for using 3D printing to improve the shear strength of a so manufactured product by altering the bead height of adjacent beads or in adjacent layers such that either the height or the centers of the beads between adjacent layers are altered. This is achieved by either height reduction or by flow rates to alter the height or positioning of the beads by altering the bead profiles the shear strength between adjacent layers in the X-Y plane is improved. The present invention is equally applicable to increasing shear strength in the Y-Z plane or the X-Z plane as desired.

Abstract: The present invention provides a method improving the shear strength of a 3D manufactured product by inserting infill into the interstices between the bead layers.

Abstract: The present invention provides a fixture or device which is particularly adapted for installation within the interior of a general aviation aircraft, such as a small private jet, prop-driven plane, helicopter, spacecraft, or other aviation vehicle. A plurality of UV-C lamps, typically LEDs are disposed within the fixture and project the radiance therefrom into the cabin, as well as control electronics to ensure safe emission limits by the LED. A temperature sensor minimizes LED burnout.

The device, generally, comprises a two-piece or two-part assembly, having a base and a cover which mounts to the ceiling or wall(s) of an aircraft. A UV-C lamp, typically an LED, is disposed within the fixture and projects it therefrom into the cabin, as well as control-electronics to ensure safe emission limits by the LED.

Abstract: A manufacturing system includes a configurable positioning apparatus and machining system for processing a workpiece retained by the positioning apparatus. The positioning apparatus has different configurations for retaining different types of workpieces, such as panels, fuselages, airfoil skins, and engine housings. The positioning apparatus includes a first support rail and a second support rail spaced apart from the first support rail. The first and second support rails support a plurality of stackable headers that cooperate to position the workpiece. The headers have adjustable heights along their lengths in order to accommodate the shape of the workpiece.

Abstract: A workpiece is cut by being selectively moved along a first axis under a cutting device, the cutting device being selectively moved along a second axis that is perpendicular to the first axis. Motion of the workpiece and the cutting device is controlled to cut a workpiece. In one embodiment of the invention, the workpiece is selectively moved along the first axis by actuation of a first linear motor, and the cutting device is selectively moved along the second axis by actuation of a second linear motor. The cutting device may be a high-pressure fluid jet system.

Abstract: Automated system for trimming and inspecting complex composite aircraft parts. A straight firing abrasive water jet head with integral catcher mounted on a first Z axis slide is numerically controlled on a six axis gantry/water jet manipulator (X, Y, Z, C, A, B axes). A touch probe mounted on a second Z axis slide is used to gauge three part points which establish part orientation in the X, Y, Z gantry/robot cell; also to adjust CNC and CMM part trim/inspection programs to actual part orientation and for peripheral dimensional inspection.

Abstract: An anti-backlash rack and pinion drive system comprising a pair of spur gears on parallel shafts engaging a rack with countertorque preload imposed by a positive timing belt engaging a pair of pulleys respectively coupled to the shafts. Slack on one side and a resilient transverse load applied to the other side of the belt provides counterspur gear tooth pressure on the rack equal to the maximum drive load effected through reversible rotation of one of the shafts.
