Abstract: A retention apparatus, system and method is useful for attaching items, panels or other devices to a rail formed in longitudinal lengths and configured with a cross-sectional profile having multiple cooperating structures between the rail and a channel nut. Self-aligning, mating structures include a recess formed between a tooth and shelf on an interior first channel portion of the rail and a flange of the channel nut with concurrent mating of an anchor latch of the rail and a hook flange on the channel nut. Latching of the channel nut is accomplished initially by compression of the biasing element as the channel nut is inserted and then, upon release, biasing element-induced movement of the channel nut into a latching position. Grounding spikes on the biasing element form electrical contact points between the rail, the clamp and the frame of the solar panel or other device.

Abstract: A scramjet engine with a novel isolator is disclosed herein. The scramjet includes an air inlet configured to receive and direct air into the engine and a combustor operable to receive air from the air inlet and combust fuel therein as is conventional. An isolator is positioned between the air inlet and the combustor. The isolator includes a primary flow path separated into a plurality of separate secondary flow channels formed therethrough. The smaller secondary flow channels prevent shockwaves from propagating upstream from the combustor to the inlet that can occur during some operating conditions of a supersonic combustion flow process.

Abstract: The present invention relates to a bar system for securing a snow fence to a membrane pad assembly connected to a structure. The bar system comprises a base bracket with an arm attachment portion having one or more openings and an arm bracket comprising one or more openings for operably connecting to the arm attachment portion using fasteners. At least one of the openings in the base bracket is configured to operably connect to the membrane pad assembly. At least one of the one or more openings in the arm bracket comprising an arcuate opening so as to allow movement along X,Y and rotational axis, e.g. horizontally, vertically and/or to allow the arm bracket to move between an open position and a closed position relative to the arm attachment portion so as to allow entry of a bar extrusion. The bar extrusion being secured by the fasteners in the one or more openings between the arm attachment portion of the base bracket and the arm bracket so as to hold snow, ice and other objects.
