Abstract:
An air bag module (10) comprising a housing (12) having sides (14) and an open mouth (18); an air bag (22) mounted within the housing prior to deployment of thereof in a compact configuration; a retainer flap (100) comprising a single piece of material, having a tearable region (110) thereon, enveloping the air bag to retain the air bag in its compact configuration prior to deployment and being of sufficient length such that upon deployment of the air bag, the flap (100) is extendible to lie between the mouth of the housing and the deployed air bag to protect the air bag. The flap having a main body (102) and the at least one leg (104) extending therefrom having mounting openings (108) for attaching the flap to corresponding mounting fasteners (54), wherein the length of the main body is sufficient to extend beyond the mouth of the housing after the tear regions have been severed upon the deployment of the air bag to provide a protective layer between the housing (and/or instrument panel) and the deployed air bag.
Abstract:
A system (20) for controlling the effective rate at which an air bag is filled comprising: a housing operatively communicated with the air bag such that as the air bag is pressurized by inflation gas such gas enters the housing increasing its internal pressure, the housing (22) including: variable vents (50a, 50b) for defining openings through which a quantity of inflation gas is controllably diverted from the air bag to thereby reduce its rate of in flation from that rate which is achieved when the vent means are closed.
Abstract:
Blast resistant and blast directing container assemblies (11, 12, 13) for receiving explosive articles and preventing or minimizing damage in the event of an explosion. The container assembly (11, 12, 13) comprises a container of blast resistant material and a blast mitigating material (14) located within the container. The container is collapsible for storage when empty. The container assemblies have utility in aircraft, where weight is an important consideration, as cargo holders or containment devices in the passenger cabin. They also are useful as transport devices for hazardous materials such as gunpowder and explosives, e.g., bombs and grenades.
Abstract:
A method for the preparation of 1,1,1,3,3-pentafluoropropane (HFC-245fa) and 1-chloro-3,3,3-trifluoropropene (HCFC-1233). 1,1,1,3,3-pentachloropropane (HCC-240fa) is fluorinated with HF in a vapor phase in the presence of a vapor phase catalyst. The HCFC-1233 and any co-produced 1,3,3,3-tetrafluoropropene (HFC-1234) are recycled for further fluorination by HF for a greater than 99 % HCC-240fa conversion.

A quench surface rapidly solidifies molten alloy into strip having a microcrystalline or amorphous structure. The surface is composed of a thermally conducting alloy having a homogeneous microstructure consisting of fine equiaxed recrystallized grains. The grains exhibit a tight Gaussian grain size distribution. The average size of said grains being less than 200 mum and none of said grains being larger than 500 mum.
Abstract:
A method for extracting mechanical energy via a Rankine cycle using hydrofluorocarbons. In particular, the invention concerns method for extracting mechanical energy via a binary Rankine cycle using pentafluoropropanes and hexafluoropropanes as working fluids for the secondary stage fluid. The system derives its energy from the temperature difference between a low grade thermal source, such as exhaust steam from a turbine, and a high quality low temperature source such as a water near its freezing point, for maximum efficiency.
Abstract:
An environmental control system for use in a transportation machine, with the system being effective for receiving and conditioning a heated, ozone-containing airstream prior to delivering the airstream to a habitable space within the machine. The system comprises a catalytic reactor (74) including a housing and a core structure disposed within a generally cylindrical portion of the housing. The core structure is made of a catalytically-active metal alloy which is effective for decomposing at least a portion of the ozone present in the air as the ozone-containing air flows between the inlet end and outlet end of the core structure. The catalictically-active metal alloy comprises a silver-containing metal alloy and may comprise an alloy having silver and copper as the principle constituents. The catalytically-active metal alloy may optionally be thermally activated for use in low temperature applications. The core structure is brazed to the housing of the reactor and may comprise a plurality of fin assemblies, each configured as an annular ring, which are generally concentrically disposed relative to one another about an axially extending centerline axis of the reactor, and with each of the fin assemblies being brazed to radially adjacent ones of the fin assemblies so as to prevent nesting between radially adjacent pairs of the fin assemblies. The system may further include at leat one heat exchanger disposed downstream of the catalytic reactor for the purpose of cooling the airsteam discharging from the reactor prior to delivering the airstream to the habitable space of the machine.
Abstract:
Provided are azeotropic and azeotrope-like mixtures of 1,1,1,3,3-pentafluoropropane (HFC-245fa) and hydrogen fluoride. Such are useful as an intermediate in the production of HFC-245fa. The latter is useful as a nontoxic, zero ozone depleting fluorocarbon useful as a solvent, blowing agent, refrigerant, cleaning agent, aerosol propellant, heat transfer medium, dielectric, fire extinguishing composition and power cycle working fluid.
Abstract:
A process for the separation of mixtures containing halocarbons and hydrogen fluoride. Either water alone or a blend comprising water and hydrogen fluoride is added to a mixture comprising a halocarbon and hydrogen fluoride to thereby form a first phase rich in the halocarbon and a second phase rich in hydrogen fluoride and water. The most preferred halocarbon is 1,1,1,3,3-pentafluoropropane. Preferably the first and second phases are then separated. Optionally the second phase rich in hydrogen fluoride and water is also separated.
Abstract:
A glassy metal alloy consists essentially of the formula FeaCobNicMdBeSifCg, where "M" is at least one member selected from the group consisting of molybdenum, chromium and manganese, "a-g" are in atom percent, "a" ranges from about 30 to about 45, "b" ranges from about 8 to about 18, "c" ranges from about 20 to about 45, "d" ranges from about 0 to about 3, "e" ranges from about 12 to about 20, "f" ranges from about 0 to about 5 and "g" ranges from about 0 to about 2. The alloy can be cast by rapid solidification into ribbon, cross-field annealed to enhance magnetic properties, and formed into a marker that is especially suited for use in magneto-mechanically actuated article surveillance systems. Advantageously, the marker is characterized by substantially linear magnetization response in the frequency regime wherein harmonic marker systems operate magnetically. Voltage amplitudes detected for the marker are high, and interference between surveillance systems based on mechanical resonance and harmonic re-radiance is virtually eliminated.
