Abstract: A common manifold, which is connectable to a source of pressurized gas, is connected via two symmetrical sets of rigid components to respective coupling elements, which are connectable directly to vessels to be charged with gas. Since there is no flexible hose section the risk of bursting at high pressure is obviated. To facilitate connection of vessels at any convenient position each set preferably includes at least one component which is rotatable and at least one elbow joint.

Abstract: This tool envisions a method for separating clinched together first and second components of a duct, which components have been clinched into interengagement, by the uncrimping of the clinch collar tab of the first component from the second component. The clinched parts are first pried loose by a sharpened point of a tool which is penetrated between the tab and the second component. The prying is continued by virtue of the use of the fulcrum, integral with the tool, so that the tab is moved from its initial 90.degree. dihedral position to its subsequent zero degree dihedral position.

Abstract: A system for collecting used oil from an engine and/or pouring new oil into the engine. The system envisions an open-topped drain pan which can be used in draining the oil, the drain pan being placed below the drain plug of the engine. The wide mouth of the open top ensures against oil spillage on the pan side wall. The pan is also provided with a top or cover having a diameter complimental to the pan diameter and is threadedly engageable therewith for sealing purposes when sealing is desired. The cover includes a spout at one side thereof to facilitate the draining of the used oil therefrom if such is desired or the pouring of new oil from within the pan into the engine, also as desired. The pan also includes a manually engageable rim portion for facilitating the transport of the pan to a distant location for the proper disposal of the used oil.

Abstract: An insulation panel having back and front faces spaced apart parallel to each other. A female edge has a recessed region along part of its length and a male edge has a complementary shape to the recessed region of the female edge so as to closely fit within the female edge of an adjacent similar insulation panel. A web extends across the distance separating the back and the front faces, the web being formed integrally with one of the faces. The female edge is generally channel shaped and has a base wall being defined by the web, the front wall comprising an edge portion of the front face which is turned inwardly towards the back face and then turned back upon itself to define a double thickness front wall of the channel shape, the edge portion of the front face turning to extend towards the back face so as to define the web. The male edge is also channel shaped but is stepped in so as to define a narrower width channel shape to fit within the female edge channel shape.

Abstract: A method of feeding a high impedance point of an antenna, such as the end of a 1/2 wave radiator. A resonant cavity is used for making an impedance match between the antenna and the feed line and forming a decoupling mechanism for forming the high impedance. Simultaneously, the cavity choke is formed with the open end facing toward the feed point for allowing a feed point impedance transformation between the feed line and the high impedance at the end of the 1/2 wave element and forming a high impedance point by its resonance for preventing the feed from flowing down along the outer surface of the choke and feed line.

Abstract: A system for attaining an impedance match uses an array of collinear dipoles. By the shifting of the feedpoints away from the centers of the dipoles, the match may be made to any desired input feedpoint impedance.
