Abstract: An exhaust containment system comprised of a collection vessel, filter, compressor and storage vessel with a valve is described. Exhaust cools (if necessary) in the collection vessel. The filter removes particulate matter and exhaust is then compressed into the storage vessel to be recycled. This system reduces exhaust released into the environment.

Abstract: Additives such as chemical elements, microstructures, time degradable molecules, micro oscillators (clocks) etc. are introduced into inks at production. The additives can be analyzed in samples thus giving source of and date of production. By varying additives over short time spans estimates of date of use may be obtained.

Abstract: A fabric is constructed to act as a diffraction grating for deBroglie waves of the continuous electromagnetic spectrum. The fabric is made by coating or laminating emissive layers on each side of a fabric and then etching one side to create a diffraction grating. The thickness of the fabric and the width of the etch determine diffracted wave lengths. Constructive or destructive interference can be established to increase the energy (constructive) or decrease the energy (destructive) of the waves diffracted proportionate to the amplitude squared.

Abstract: An aircraft landing assist system comprised of a preformed and prepacked parawing-bag and fuselage housing and deployment is described. In case of emergency the system can be deployed automatically, manually, or by means of explosive charge. After deployment the open doors and the self inflated parawing-bag catch the on rushing air forcing the nose of the aircraft up. This helps increase the glide ratio and decrease the velocity of the aircraft. Control of the aircraft remains through the use of the upper wing surfaces and tail assembly. Upon landing the system helps extend the time of, and surface area of impact. Drains are provided in the aft section of the parawing-bag(s) to release rain or snow.

Abstract: A tent is fabricated from a seamless spherical shell. The floor of the tent is established as a plane interiorly dividing the shell into two chambers. The floor peripherally contacts the inner surface of the shell, and is sealed against the inner surface of the spherical shell. The larger chamber serves as the living chamber, while a smaller air tight chamber is formed between the floor and the shell. The air tight chamber is provided with a valve communicating with the outside environment. When the tent is disassembled, and with the valve opened, the spherical shell will completely deflate and collapse. During erection of the tent, the air chamber valve remains open, and the shell's cap over the floor is manually pulled out away from the tent floor causing a vacuum to form in the smaller airtight chamber. Air immediately flows through the valve filling the air chamber, and by closure of this valve the air is trapped. The air cushions the floor to provide a self inflated air mattress.
