20080289258 | Separation Structure for Isolating a Delimited Space from the External Environment - A separation structure ( | 11-27-2008 |
20090049754 | System for use in a vertical furnace - A system used in a vertical furnace is provided that includes a tube. The tube includes a tube flange at its lower end. The tube flange provides a first sealing surface at its lower end. Further, there is a structural member at the lower surface of the tube flange. This structural member extends vertically away from the lower surface of the tube flange at a position that is displaced inwardly from the first sealing surface. The system also includes a removable door plate that provides a second sealing surface at its upper surface. The second sealing surface of the removable door plate is sealed with the first sealing surface of the tube flange. | 02-26-2009 |
20090255187 | ACTIVE SEAL ARCHITECTURES - Active seal architectures adapted for producing a variable sealing and/or closing force between a closure panel and perimeter, includes a mounting clip, a flexible outer layer fixedly connected to the clip, defining an interior space, and longitudinally extending along the perimeter; and an interior structure comprising and reconfigurable by an active material disposed within the space, and operable to impart differing first and second forces upon the layer and panel when the material is activated and deactivated respectively. | 10-15-2009 |
20100132264 | BI-FLOW INFLATABLE DOOR SEALS - An example of an inflatable seal for a door includes a bi-directional airflow pattern of frost-inhibiting heated air. The bi-directional flow pattern enables the seal's discharge opening and supply air blower to both be located well above the floor and preferably above the doorway. If the discharge opening is near the suction inlet of the blower, such an arrangement makes it possible to recover previously heated air by returning some of the warm air back to the blower. In some examples, the seal includes a supply air conduit and a return air conduit with one disposed within the other. The internal conduit may include a relatively stiff elbow to prevent that conduit from becoming kinked near an upper corner of the door. | 06-03-2010 |
20110126472 | Seal assembly with leak test components - A seal assembly is provided for maintaining a pressure difference between an exterior and an interior of an object having an access hatch and an access hatch frame. The seal assembly has a seal retainer having an interior face oriented toward the interior of the object, an exterior face oriented toward the exterior of the object, a hatch-side face oriented toward the access hatch and extending from the interior face to the exterior face, and frame-side face oriented toward the access hatch frame and extending from the interior face to the exterior face. The seal assembly also has at least one sealing member mounted on either the interior face or the exterior face of the seal retainer and a plurality of conduits formed in the seal retainer and extending from the exterior face to the interior face. The plurality of conduits include at least one supply conduit located between either the hatch-side or frame-side face and the at least one sealing member and at least one return conduit located so that the at least one sealing member is positioned between the at least one supply conduit and the at least one return conduit. | 06-02-2011 |
20110258934 | DOOR AND SYSTEM PROVIDING RADIO FREQUENCY SHIELDING AGAINST HIGH-ALTITUDE ELECTROMAGNETIC PULSE - Pneumatic door system of fluid lines, valves, switches, and sensors integrated into hinge mechanisms, door frame, and door connected to a fluid pressurization system to inflate and deflate one or more fluid seals attached to outer perimeter of door adjacent to inner perimeter of door frame to close gap between outer perimeter of door and inner perimeter of door frame to provide radio frequency shielding against, for example, high-altitude electromagnetic pulse. Air seal creates a substantially impermeable barrier against radio frequency transmission, as well as air infiltration, when fully inflated. Separate fluid channels in each component interconnect to act as one fluid circuit or network when door is closed. Pneumatic door system can be fluidly connected to a conventional fluid pressurization system in communication with a programmable logic controller to respond to user input or automatic commands with system overrides to react to system air pressure and air flow conditions. | 10-27-2011 |
20120260579 | Multiple Hollow Bulb Seal - A seal that includes a hollow bulb that defines an interior space, and further includes at least one solid divider wall located in the interior space in order to divide the interior space so that it includes at least a first chamber and a second chamber, where the first and second chambers are not in fluid communication with one another. In some preferred embodiments: (i) the interior wall is generally V-Shaped in transverse cross-section; (ii) the first chamber is generally triangular in transverse cross-section; and (iii) the second chamber is generally U-shaped in transverse cross-section. Some preferred embodiments further include a seal base (for example, a T-shaped base), with the hollow bulb being mechanically connected to the base at the bottom of the T-shape so that an open end of the V-shaped interior wall is oriented to directly face the seal base. In some preferred embodiments, the first and second chambers are hollow. | 10-18-2012 |
20120317887 | DEVICE FOR CLOSING AN OPENING IN A CHAMBER WALL - Device for closing an opening in a chamber wall of a low-pressure chamber or vacuum chamber, which has at least one movably mounted closure element ( | 12-20-2012 |
20130047519 | Inflatable Door Seal - A vehicle and method of operation having a first door, a second door, an inflatable door seal assembly and an inflator assembly. The first door has a first opening side and a first seal mount extending along the first opening side. The second door has a second opening side adjacent to the first opening side to define a gap and a second seal mount extending along the second opening side. The door seal assembly has a first seal assembly mounted to one of the first or second seal mounts, the first seal assembly inflatable to extend into the gap toward the other of the seal mounts when the first and second door are closed and deflatable to retract from the gap. The inflator assembly pumps a fluid into the seal assembly to inflate the seal assembly and pumps the fluid out to deflate the seal assembly. | 02-28-2013 |
20140360100 | SEAL PROFILE OF A DOOR SEAL - A door seal for a doorway in a vehicle for public passenger transportation has at least one reinforcing element coated with an elastomer, the reinforcing element having a lesser elasticity in the longitudinal direction of the seal than in the transverse direction. | 12-11-2014 |
20150082708 | COVER PLATE AND DOOR ARRANGEMENT FOR A MEANS OF TRANSPORTATION - A cover plate for covering a door clearance between a skin of a means of transportation and a door as well as a door arrangement with such a cover plate is proposed. The cover plate includes a mounting region for permanently fastening the cover plate on the door; a covering region for covering the door clearance; and a fastening device that is designed for fixing the covering region on the skin when the door is closed. | 03-26-2015 |
