Abstract: An apparatus and a method for generating repetitive planar detonation waves at varying and controllable frequencies are provided. The apparatus utilizes the over-pressure associated with each detonation wave to interrupt the ambient pressure, post-injection mixing of the reactant gases between the detonation cycles. In-line mechanical valves can be used to positively interrupt one or both reactant gases if the reaction within the detonation tube degrades to deflagrative burning. The detonation system can be optimized during operation by monitoring either the detonation wave pressure or velocity and adjusting the reactant gas mixture accordingly.

Abstract: A collapsible, reusable, livestock transport stable with interchangeable components that can be constructed without tools. The stable includes several types of component parts, with like parts each being interchangeable and useable in any position where such a part is needed. The first of those component parts is a platform which serves as the base of the stable. Next, there is a pair of side panels, each of which is rotatably attached to the side edges of the platform for providing the vertical sides of the stable. Interconnecting the two side panels is an aft panel. The aft panel is isntalled by resting its lower edge along the aft edge of the platform, its two vertical edges are captured by the side panels when the side panels are in the vertical attitude. The doors are attached to the forward edges of the side panels to provide closure of the stable.
