Abstract: A video display system utilizing a video source and an image intensifier having a substrate. A video image source positions at the substrate to provide a photon signal. A photocathode element at the substrate converts the photon signal into electrons. An optically transparent body having first and second surfaces is placed opposite the substrate spaced therefrom. A vacuum chamber is formed between the substrate and the first surface of the second optically transparent body. A fluorescing layer is positioned on said first surface of the second optically transparent body. A source of electrical power provides a voltage potential between the photocathode layer and said fluorescing layer. The intensified video image exits the second surface of the second optically transparent body for viewing.
Abstract: A filter cartridge for separation of aqueous colloidal suspensions utilizing a shell which forms a chamber having a colloidal suspension inlet and outlets for permeate and concentrate streams. A core is placed within the shell and includes a plurality of filter elements which are located in overlying relationship with one another. Each filter element possesses a relative rigid backing member and a filter membrane. The core is fastened to the shell by connecting a plurality of the backing members to the body of the core.
Abstract: A video display system utilizing a video source and an image intensifier having a first optically transparent body including first and second surfaces. The first surface receives the video image while the second surface includes a layer of photocathode material. A second optically transparent body having first and second surfaces is placed opposite the first optically transparent body and spaced therefrom, A vacuum chamber is formed between the second surface of the first optically transparent body and the first surface of the second optically transparent body. A fluorescing layer is positioned on said first surface of the second optically transparent body. A source of electrical power applies a voltage potential between said photocathode layer and said fluorescing layer. The intensified video image exits the second surface of the second optically transparent body for viewing.
Abstract: A drive mechanism for a body utilizing a motor which rotates a shaft. An eccentric weight is mounted on the shaft for movement with the same. The eccentric weight is linked to a base weight and transmits an oscillational motion along a dimension of the base weight. A torsion spring fixed to the counter weight extends away from the base weight and connects to the body to impart an oscillational torsional motion thereto.
