  • Patent number: 4850380
    Abstract: A system for decontaminating persons or objects passing between a contaminated area and a clean area or shelter has an air lock decontamination chamber and a shower of powdered adsorbent. A blower circulates and disperses the powdered adsorbent throughout the air lock and contacts the adsorbent particles with the outer surfaces of persons or objects in the air lock. A control system ensures that the decontamination system is fool-proof. A network of ducts and valves or separators automatically transfers the adsorbent from the deccontamination chamber to a regeneration chamber for demand-responsive regeneration. In a first embodiment, a fluidized bed of powdered absorbent is used in the decontamination chamber and the adsorbent is periodically regenerated in a vacuum chamber by microwave heating.

    Abstract: An inflatable, inert-gas purged welding chamber assembly ideally suited for use in welding workpieces made of a metal (e.g., titanium), or of an alloy, which is susceptible to atmospheric contamination during welding. The welding chamber of the assembly is defined by a collapsible, reusable, inflatable member (e.g., a polyethylene bag) that is releasably connected to a closeable opening in a wall member. The inflatable member, while in a collapsed condition and while containing the workpieces to be welded and the accessories therefor (e.g., a welding torch, extra tungsten electrodes, and filler wires) on a shelf protruding from the wall member, is purged of air (i.e., the ambient atmosphere) by the use of an inert gas (e.g., argon), thereby inflating the collapsed member and creating an inert gas environment in which the air-contaminable workpieces can be welded without fear of contamination.

  • Patent number: 4010588
    Abstract: A device for sealing detachable components, such as gloves, windows or closure plugs, in the ports of rigid walled chambers, such as glove boxes. The sealing device permits displacement and replacement of a detachable component in place in such a port without breaking the seal to expose the interior of the chamber to the outside atmosphere, or vice versa. The sealing device is characterized by a hand hole bushing disposed in the port and secured to the chamber wall to define a passageway having a continuous sealing surface and a continuous adjacent groove for retaining a detachable component within the bushing. The detachable component is characterized by a deformable semi-rigid bead adapted to be snapped into the continuous groove of the bushing and a continuous channel holding an O-ring sealing element which engages the sealing surface of the bushing.

  • Patent number: 3971644
    Abstract: A mixing tank and filtration system for operating room use. The tank is utilized for mixing a cement that is employed in reconstructing joints such as the hip joint, and mixing must take place in the operating room because the cement sets up in a very short time. The only presently approved cement gives off toxic fumes during the mixing which fumes frequently have a detrimental effect on the patient and operating room personnel. The mixing tank and filtration system disclosed herein are constructed and arranged to contain and draw off the toxic fumes whereby the detrimental effects on personnel are eliminated.

  • Patent number: H460
    Abstract: A decontamination system in combination with a work space maintained at subambient pressure. An inner vestibule is connected to the work space via a first portal, which can be selectively opened and closed by a first door. A middle vestibule, in which at least one shower bath is installed, is connected to the inner vestibule only via a second portal, which can be selectively closed by a second door or opened. An outer vestibule is connected to the middle vestibule only via a third portal, which can be selectively opened and closed by a third door, and to an ambient space only via a fourth portal, which can be selectively opened or closed by a fourth door. Each door is a rigid door. Except for the third door, which seals the third portal when the third portal is closed by the third door, each door has fixed louvers allowing small quantities of air to infiltrate.
