Abstract: The present disclosure describes a chamber with an interior UV reflective surface, and a light source emitting an ultraviolet light that is used to kill microorganisms on one or more surfaces of an object, thereby sanitizing the object.

Abstract: An ultraviolet flux multiplying air sterilization chamber comprises inner surfaces having a diffuse reflective behavior. The sterilization chamber includes an inlet aperture and an outlet aperture for air to flow through said chamber and a light source emitting an ultraviolet light. Due to the reflectivity of the inner surfaces of the chamber, a flux of the ultraviolet light is multiplied by reflecting multiple times from the inner surfaces of the chamber. The inlet and outlet apertures are advantageously configured to reduce the amount of light that escapes from the chamber and increase the amount of photons available in the chamber. In an exemplary embodiment, perforated end panels having diffuse, reflective interior surfaces may be provided over at least a portion of the inlet and outlet apertures.

Abstract: The present disclosure relates to an apparatus and its methods of use which provides a reflective cavity technique that significantly increases the intensity and uniformity of UV energy, enabling very high and uniform UV irradiance. The high UV irradiance and high uniformity lead to previously unobtainable levels of air sterilization.

Abstract: A programmable interference system for use with clustered radio transmitters and receivers operating aboard aircraft, as well as seafaring or land based installations, and which may interfere with each other. The invention uses a central processing unit with associated memory which provides pulse treatment including delay and/or extension of the blanking pulses as generated by the radio transmitters and such that the pulse treatment may be programmed by preselecting and storing the parameters of the pulse treatment in the memory from where they may be called into operation to control variable delay and extension circuit elements. The invention is especially suited to operate with aircraft having a multiplex bus that carries all the control data from flight controls as well as from the cockpit on a time divided multiplexed basis.

Abstract: 1. In a missile guidance system, that improvement which comprises, a missile having a rotatable section, a fin on the section adapted to rotate the section as the missile passes through the air and to steer the missile when the cone section is braked, an optical slit on the section, an electrical generator rotated by the section, means responsive to radiation from a target received by said slit to short the generator, thus providing a brake on the section so that the fin will steer the missile toward the source of radiation.

Abstract: In the present invention an elongated fabric web is advanced horizontally across a table by motor-driven rollers in a horizontally pivoted web forming device. The web forming device folds the web up along longitudinal fold lines before passing it through an opening in a metal fastener member held upright by a horizontally pivoted holder. The web forming device is pivotally retracted upwardly, and a web folding device folds over the leading end of the web and also rocks the holder to move the fastener member to a substantially horizontal position during this fold-over operation. A label is applied to the top of the web before the fold-over operation. The folded-over web and the applied label are slid across the table by a transfer device to a position where an automatic sewing machine sews a permanent end loop in the web and sews the label to the web next to this end loop.
