Abstract: A reconfigurable, transportable container assembly is provided. Side panels are releasably interconnected with each other and combine with a base panel, and a top panel releasably mates with the side panels. The top panel is combined with the side panels and the base panel to form a transport configuration that defines a closed, transportable, collapsible container, and that is reconfigurable to a nontransport configuration that defines a substantially stationary structure different from the transport configuration. Embodiments can include deployable wheel assemblies and extendible jack assemblies connect to the base panel.

Abstract: Under one aspect of the invention, a reconfigurable, transportable container assembly is provided. Side panels are releasably interconnected with each other and combine with a base panel, and a top panel releasably mates with the side panels. The top panel is combined with the side panels and the base panel to form a transport configuration that defines a closed, transportable, collapsible container, and that is reconfigurable to a nontransport configuration that defines a substantially stationary structure different from the transport configuration. Embodiments can include deployable wheel assemblies and extendible jack assemblies connect to the base panel. It is emphasized that this abstract is provided to comply with the rules requiring an abstract. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims (37 C.F.R. 1.72(b)).

Abstract: Apparatus for attenuating a sound wave propagating in a given direction along a fluid-containing duct comprises two sound sources spaced along the duct in a given direction; a sound detector between the two sources at a null point at which sound emanating only from the two sources substantially cancels; and means for utilizing the output of the sound detector including a phase-shifter and a frequency-sensitive amplifier to control the operation of the sound sources so that they emit sound in relative antiphase and at equal amplitudes and at such phases relative to the phase of the detected sound that the resultant of the sound radiations emitted in the given direction substantially attenuates the sound wave propagating along the duct.
