Disclosed is a water resistant joint sealing system comprising a coiled, coated precompressed core material. In one embodiment, the joint sealing system includes a fire retardant material put into the core material. In one embodiment, the fire retardant material forms a layer in, or between portions of material of, the core material.

An aircraft includes first and second zones, and a sealing system, interposed between a doorframe and a door providing access to the second zone, including: a peripheral seal secured to the door, a stop secured to the doorframe, and including a body in the form of at least one plate which extends around the perimeter of the doorframe, parallel to the door when the door is in the closed position, a peripheral groove positioned on the stop in such a way that the peripheral seal closes off the peripheral groove around the perimeter of the opening when the door is in the closed position, and at least one passage configured to cause the peripheral groove and the first zone to communicate.

Fireworthy sealants may have a variety of compositions and be made by a variety of techniques. In certain implementations, a fireworthy sealant may include a body comprised of a cured, tacky, soft, deformable non-adhesive gel. The gel body may have an upper surface, a lower surface, and a perimeter, wherein the upper and lower surfaces of the gel body, in an uncompressed state, define a body thickness. The sealant may, in an uncompressed state, be dimensioned to fit in a first opening between a wall and an aircraft component surface and deformable when under compression to fit in a second opening, smaller than the first opening. The sealant may be flame retardant and produce low smoke density and low smoke toxicity.

Knit fabrics having ceramic strands, thermal protective members formed therefrom and to their methods of construction are disclosed. Methods for fabricating thermal protection using multiple materials which may be concurrently knit are also disclosed. This unique capability to knit high temperature ceramic fibers concurrently with a load-relieving process aid, such as an inorganic or organic material (e.g., metal alloy or polymer), both small diameter wires within the knit as well as large diameter wires which provide structural support and allow for the creation of near net-shape preforms at production level speed. Additionally, ceramic insulation can also be integrated concurrently to provide increased thermal protection.

A seal arrangement configured to provide an airtight and fluid-tight seal between a first component and a second component, having a first pressure boundary seal disposable at least partially within the gap between the first component and the second component, the first pressure boundary seal being fixable to one of the first or second components to create an airtight seal with the other of the first or second component, the seal arrangement also having a first flame deflector that is configured to bridge across and cover the gap between the first component and the second component so as to create a fluid-tight seal over the gap between the first component and the second component, where the first flame deflector has a convex external shape so as to prevent any fluid impinging upon the first flame deflector from pooling on the first pressure boundary seal.

High temperature dryer seals and related methods are provided. A high temperature dryer seal can include a first substrate having first and second ends and first and second sides. The first substrate can include a low-melt polymer. The first end and the second end of the first substrate can secured together so that the first substrate forms at least a portion of an annular shape. The dryer seal can also include a second substrate secured to the first substrate at the second side of the first substrate. The second substrate can include a high temperature material that has a higher melting point than the low-melt polymer of the first substrate. The dryer seal also includes a heat resistant coating attached to the second substrate with the heat resistant coating being activated at a temperature that is higher than a melting point of the low-melt polymer.

A gasket for installation in a gap defined by adjacent modular construction units, each having a support frame. The gasket includes at least one layer of structural cement panel; and at least one layer of mineral wool, and the at least one layer of said panel and mineral wool has at least one plate recess configured for accommodating a support plate. A modular building construction is provided, including a plurality of modular units, each unit having a steel frame. Four adjacent units of the plurality form an intersection, and support plates are fastened at upper surfaces of corners formed by each frame. The gasket is disposed in a gap defined at the intersection, the gasket having four plate recesses for accommodating the support plates. In still another embodiment, a method of constructing a building made of modular units including the gasket.

The invention relates to a seal for a clothes dryer adapted to be interposed between a first part and a second part of the dryer. The seal comprises a first portion adapted to be connected to the first part of the dryer and a second portion adapted to be placed in contact with the second part of the dryer. The second portion comprises an at least partially curved stretch and such an at least partially curved stretch comprises a flocked surface layer adapted to be placed in contact with said second part of the dryer.

Fire seal assemblies for aircraft engines are described herein. An example fire seal assembly includes a first L-cap having a first leg and a second leg extending outward from the first leg, and a second L-cap having a third leg and a fourth leg extending outward from the third leg. The first and third legs are to be coupled to a core service disconnect (CSD) on a pylon of an aircraft, and the second and fourth legs are to extend outward and engage sides of a firewall of an engine of the aircraft. The first seal assembly further includes a seal coupled to the first and third legs and disposed between the second and fourth legs, a first end plug disposed between a first end of the seal and the second leg, and a second end plug disposed between a second end of the seal and the fourth leg.

A fire-protection apparatus contains a housing with a passage, and an insert containing a plurality of sections made of a flexible material.
