Abstract:
Towed aerodynamic platforms approach the behavior of flat plate airfoils to achieve high lift -to-drag (L:D) performance when operated at low pitch angles. A lead aircraft may tow multiple platforms to form train units. Low form drag and high L:D enable solar aircraft that are more robust and faster than approaches extending wingspan rather than extending the length of the aerial train. Applications extend beyond solar aircraft and include vehicles towed along an overhead monorail system and aerial drones.
Abstract:
Electrode compositions and devices (100) that incorporate the electrode compositions are provided. More specifically, electrode compositions that include carbon that provide a connective network to which metal and/or metal derivatives are deposited are provided. Convection battery devices (100) that incorporate the carbon electrode compositions are also provided.
Abstract:
A motor (more-broadly, induction device) is based around stacked rotor and stator boards rather than coils. The advance is analogous to using circuit boards rather than wires. Distinct advantages exist when the circuit board motor embodiment is combined with a novel open- burner combustor to form a hybrid electric-fuel jet engine (a culmination of three embodiments). The preferred application of the hybrid fuel-electric engine is in highly efficient (high lift-to- drag) aircraft utilizing towed platforms having high surfaces areas for both generating lift and collecting solar energy. The final combination yields advantages for an aerial platform towed via a front hinge joint that enables both vertical takeoff/landing and advantageous failsafe landing options. The aircraft is preferably powered by the hybrid electric-fuel jet engine.
Abstract:
The Terreplane Transport System is a ground-based transportation comprised of flying vehicles pulled by a propulsion line. An important design feature of the most preferred system is that the propulsion line only experiences longitudinal forces during flight making low-cost propulsion lines possible. A propulsion carriage engages the propulsion line to create acceleration. A connection arm connects the vehicle to the propulsion carriage whereby the cumulative interaction includes the ability to convert impacting and overflowing air into lift complete with control to provided controlled flight based on the longitudinal force conveyed from the propulsion line to the propulsion carriage. The preferred method of conveying the longitudinal force is through linear motors utilizing novel longitudinally asymmetric coils.
Abstract:
The present invention provides processes for the gas phase conversion of a polyhydric feedstock into an oxygen-containing product. The polyhydric feedstock comprises water and at least one polyhydric compound having from about four to about twelve carbon atoms and more than three hydroxyl groups. Also provided are processes for the separation of the oxygen-containing product from the reaction product mixture.

Abstract:
The abstract was not in accordance with PCT Rule 8.1(b) because it was more than 150 words in length. The abstract has been established by this Authority to read as follows: The invention provides processes for preparing soy-based oligomeric polyols or substituted oligomeric polyols, as well as urethane bioelasteromers comprising the oligomeric polyols or substituted oligomeric polyols. The presently disclosed processes advance the art and overcome problems associated with the conversion of vegetable-derived triglycerides into polymers. Accordingly, the processes produce polyols with unique and improved properties. One aspect of the invention provides a process for preparing an oligomeric polyol. The process comprises contacting a soy-based epoxidized triglyceride with a hydroxyl-containing reactant in the presence of an aromatic sulfonic acid. Another aspect of the invention encompasses a urethane bioelastomer formulation comprising a phosphate ester -substituted polyol, wherein the formulation has a tensile strength at break of at least about 0.4 MPa.
Abstract:
A reactive-separation process converts glycerin into lower alcohols, having boiling points less than 2000C, at high yields. Conversion of natural glycerin to propylene glycol through an acetol intermediate is achieved at temperatures from 150° to 2500C at pressures from 1 and 25 bar. The preferred applications of the propylene glycol are as an antifreeze, deicing compound, or anti-icing compound. The preferred catalyst for this process in a copper-chromium.
Abstract:
The Glider Guideway System (also referred to as Terreplane Transportation System) is a ground-based transportation comprised of flying vehicles pulled by a propulsion line. An important design feature of the most preferred system is that the propulsion line only experiences longitudinal forces during flight making low-cost propulsion lines possible. A propulsion carriage engages the propulsion line to create acceleration. The system include novel embodiments for linear motor stators that travel on cable guideways, a method to connect cable guideways without obstructing the path of the linear motor stators, suspended post embodiments that reduce propulsion line tension and reduce required support tower heights, and novel open loop coils for use with cable guideway armatures.
