20140233017 | Measurement of Solid, Aerosol, Vapor, Liquid and Gaseous Concentration and Particle Size - A method and apparatus for measuring particle content in a stream, comprising routing the stream, via a plurality of tubes, from a plurality of sampling points where particle content concentrations are to be measured. The concentration of particle content in the stream may be measured. The measurement may be based on determination, via a sensor for example, of an electrostatic charge of the particles as the particles, and/or based on counting of a number of particles in the stream, such as using a counter tracking light emitted from a light source. The measured concentration of particle content may be analyzed to determine if it is indicative of an appropriate concentration of measured particles in the stream. The particles may comprise extinguishing and/or suppression agent particles. | 08-21-2014 |
20150069068 | CONTAINERS FOR FIRE CONTAINMENT - A container includes a fire-retarding material, a substantially airtight cavity, and a reinforcement material. The substantially airtight cavity is formed by the fire-retarding material and is sized to hold at least one item. The reinforcement material is connected with the fire-retarding material. | 03-12-2015 |
20150069069 | FIRE-RETAINING CONTAINERS - A fire-retaining container is disclosed which includes a first fire-retarding layer and a second fire-retarding layer connected to the first fire-retarding layer. Another fire-retaining container is disclosed which includes a fire-retarding layer and a reinforcement material reinforcing the fire-retarding layer. A method of containing an item is disclosed. In one step, an item is covered with a fire-retaining container. The fire-retaining container comprises: (1) a first fire-retarding layer and a second fire-retarding layer connected to the first fire-retarding layer; or (2) a fire-retarding layer and a reinforcement material reinforcing the fire-retarding layer. | 03-12-2015 |
20150266561 | SEAL DESIGN FOR VEHICLE AND STRUCTURE APPLICATION - Provided is a captured seal assembly that can be positioned between a first surface and a second surface of a structure or vehicle, such as an aircraft. The captured seal assembly includes a geometric-shaped seal such as a bulb-shaped seal that can be secured to an outer perimeter of the first surface and a receiving land capture that can be secured to an outer perimeter of the second surface. The geometric-shaped seal is designed to engage with the receiving land capture, and join the first surface and second surface when the geometric-shaped seal is engaged with the receiving land capture. In addition, the seal assembly can maintain a differential in pressure between a first region adjacent to the first surface and a second region adjacent to the second surface. | 09-24-2015 |
20150297923 | FIRE-RETARDING APPARATUS AND METHODS OF THEIR MANUFACTURE - A fire-retarding apparatus includes a composite. The composite includes a face layer attached to a fire-retarding layer. | 10-22-2015 |
20160138737 | FIREPROOF FLEXIBLE HOSES WITH POLYIMIDE INNER STRUCTURES - Provided are fireproof flexible hoses, aircraft having fire suppression systems including such fireproof flexible hoses, and methods of forming such fireproof flexible hoses. A fireproof flexible hose includes an inner structure and an outer structure at least partially enclosing and directly interfacing the inner structure. The inner structure forms an inner surface of the fireproof flexible hose and includes a polyimide at least at the inner surface. The polyimide has good fireproofing and temperature resistant characteristics and, unlike other polymers, does not need to be thermally isolated when the hose is exposed to fire. The outer structure may be made from metal and/or non-metal and may provide mechanical support to the inner structure. The outer structure may have a convoluted shape to ensure flexibility of the overall hose assembly. In some examples, a set of gaps may be present between the outer and inner structures for additional flexibility. | 05-19-2016 |
20160138958 | Optical Impedance Modulation for Fuel Quantity Measurement - Systems and methods that use an optical impedance sensor that eliminates electricity for measuring fuel quantity in fuel tanks. The optical impedance sensor comprises two optical fibers spaced apart inside a meniscus tube, one to transmit light along its length and the other to receive light along its length. The meniscus tube minimizes the sloshing of fuel level. The fuel level in the tank modulates the optical impedance between the two optical fibers, resulting in changes in the total light received by an optical detector. Depending on fuel tank height, the optical impedance sensor may comprise different embodiments in which the detection apparatus shapes the light to be unidirectional (emitted and collected only on one side of the fiber) or omnidirectional (all directions). | 05-19-2016 |
