Publication number: 20180057191Abstract: Disclosed are the thermal protection and drag reduction method and system for an ultra high-speed aircraft. A cold source is and a cold source driving device are arranged inside a cavity of the ultra high-speed aircraft. A plurality of micropores are arranged on a wall surface of the cavity. The cold source driving device comprises an air pump, a cold source reservoir and a buffer. The air pump supplies compressed air to a cold source reservoir during operation. The cold source enters the buffer and is vaporized under the action of air pressure. High-pressure gas is ejected from the micropores to form a gas film on the outer surface of the cavity. The gas film not only can perform thermal protection on the ultra high-speed aircraft, but also can effectively reduce viscous drag between the aircraft and the external gas, by virtue of which the thermal barrier phenomenon is alleviated or eliminated. Therefore, security of the ultra high-speed aircraft is improved and service life is prolonged.Type: ApplicationFiled: February 6, 2016Publication date: March 1, 2018Inventors: Wenwu ZHANG, Shuhong XIANG, Chunhai GUO, Jingyu TONG, Tianrun ZHANG, Yang YANG, Tao SONG

Publication number: 20180057192Abstract: A stand-off panel thermal protection system is disclosed. The system comprises a sandwich panel comprising: a first ceramic matrix composite facesheet and a second ceramic matrix composite facesheet. A ceramic matrix composite core is positioned between the first ceramic matrix composite facesheet and the second ceramic matrix composite facesheet. The ceramic matrix composite core has a perimeter. The first ceramic matrix composite facesheet and the second ceramic matrix composite facesheet extend past the perimeter to form a gap between the first ceramic matrix composite facesheet and the second ceramic matrix composite facesheet surrounding the ceramic matrix composite core. A plurality of orifices are formed through the sandwich panel.Type: ApplicationFiled: November 3, 2017Publication date: March 1, 2018Inventors: Michael J. BEST, Thomas R. PINNEY, Jonathan D. EMBLER

Publication number: 20180057193Abstract: A simulated gravity device method and apparatus is presented. The simulated gravity device (SGD) is disposed in mechanical communication with a spacecraft. The SGD is rotatable about a central axis, and is capable of supporting a person therein. The SGD is rotatable at a speed resulting in various forces, said various forces dependent on a rotation speed of said SGD and on a position within said SGD. The SGD is able to simulate the force of gravity on an astronaut.Type: ApplicationFiled: August 17, 2017Publication date: March 1, 2018Inventor: David Byron Douglas

Publication number: 20180057194Abstract: An apparatus for dispensing lids has at least one magazine lane including an entrance end, an exit end, and a longitudinal length defined therebetween. The at least one magazine lane further includes a plurality of side guides along the longitudinal length for guiding the lids therebetween and a pair of rollers for carrying the lids thereon. The apparatus further has a throat plate at or near the exit end, the throat plate including an opening. At least one of the throat plate, the side guides, or the rollers is adaptable so as to accommodate different sizes and/or shapes of lids.Type: ApplicationFiled: August 9, 2017Publication date: March 1, 2018Inventors: Wade Joseph Burken, Donald Brooks MacKinnon, Daniel Leonard Matthies, Jeffrey David Wintring

Publication number: 20180057195Abstract: The packet for providing nutrients to a person is disclosed. The packet may be inserted into a bottle of water at which time, a film of the packet begins to dissolve and allow the water to seep into the packet. When the water seeps into the packet, the water dissolves the film from the inside out so that the film dissolves from the outside in and inside out to reduce the time required to completely dissolve the film. Moreover, the bottle of water can be closed so that the user can shake the bottle of water and allow the powdered nutrient in the packet to rub against the film and further reduce the time required to completely dissolve the film and also dispersed the powdered nutrient in the water. The powdered nutrient may have a rate of dissolution that is slower than the film so that the powdered nutrient can run and cause friction against the film throughout the entire period of time water bottle was shaken.Type: ApplicationFiled: May 30, 2017Publication date: March 1, 2018Inventor: Nicholas J.

Publication number: 20180057196Abstract: A tray (100) for accommodating a coiled medical device, such as a catheter assembly (700), includes a first compartment (101), a second compartment (102), and a third compartment (103). The catheter assembly (700) and devices associated with a catheterization procedure, such as syringes (701,702) containing sterile water and lubricating jelly and a specimen container (703) can be disposed within the tray. Printed instructions (1001) can be included with the tray (100). One or more layers of wrap material (2200) can be folded about the tray (100) to enclose the tray (100) and other items, such as an additional layer of wrap material (2701), packaged liquid hand sanitizer (2401), and packaged gloves (2402). When a health care services provider (3101) unfolds the wrap material, the same can be used to create a sterile field beneath a patient (3201).Type: ApplicationFiled: November 3, 2017Publication date: March 1, 2018Inventors: Jennifer E. Tomes, Sarah Dickinson, Deborah Adler, Jack Maze, Alberto Savage, Kenneth Chua, Earl Wilson, John Kutsch
