摘要:
The present invention relates to a flame resistant thermal liner comprising a nonwoven sheet comprising nanofibers of a synthetic polymer having an limiting oxygen index of at least 21, a mean flow pore of 10 micrometers or less, a thickness air permeability of 25 to 6000 cubic feet per min−micrometers (12 to 2880 cubic meters per square meter per min−micrometers), and an average thickness T1; and a thermally stable flame resistant fabric attached to an outer surface of the nonwoven sheet, the fabric having an average thickness T2; a surface of the thermally stable fabric being in contact with a surface of the nonwoven sheet; wherein T1 and T2 are selected such that the ratio of T1 to T2 is less than 0.75. The invention also relates to a flame resistant composite fabric comprising the flame resistant thermal liner and a garment comprising this flame resistant composite fabric.
摘要:
A vane ring assembly includes a lower vane ring (20), an upper vane ring (30), one or more guide vanes (80) positioned at least partially between the vane rings, and a spacer (50) positioned between the lower and upper vane rings (20, 30) for maintaining a distance between the lower and upper vane rings (20, 30). The spacer has a first end (52) with a first diameter, a second end (54) with a second diameter, and a middle section (56) with a third diameter. The third diameter is larger than the first and second diameters. The first and second ends (52, 54) of the spacer (50) are inserted at least partially into a first counter bore (22) and a second counter bore (32) formed in the lower and upper vane rings (20, 30). A nut (40) and a fastener (42) running through a central through hole (58) of the spacer (50) are used to connect the vane ring assembly to a turbocharger housing. A clearance (c) of greater than e.g. 5% of the fastener diameter is formed between an inside wall (51) of the spacer (50) an outside wall (43) of the metal fastener (42) to offset any thermal expansion or deformation.
摘要:
A vane ring assembly which includes a lower vane ring (22), an upper vane ring (30), one or more guide vanes (80) positioned at least partially between the vane rings, and a plurality of spacers (42, or 50) positioned between the lower and upper vane rings for maintaining a distance between the lower and upper vane rings. By using a first set of fasteners (190) to fasten the lower vane ring to the turbine housing, and a second set of fasteners (191) to fasten the lower vane ring to the upper vane ring, the vane ring assembly is effectively decoupled from the turbine housing with regard to differential thermal expansion, and the co-planerism of the vane rings is easier to maintain.

A sensor for detecting a parameter of an object includes a probe, a first sensing member for detecting the parameter of an object to be sensed and a second sensing member for determining an orientation of the probe relative to the object to be sensed. The second sensing member communicates the orientation of the probe to a data acquisition device to minimize data analysis errors associated with inaccurate orientation information.

An electric motor system includes an electric motor, a temperature sensor mounted therein capable of measuring a local temperature and generating a temperature related signal, and a processor configured to calculate an actual temperature of a rotor magnet from the temperature related signal, and an actual output torque from the actual rotor magnet temperature. A method for determining the actual output torque of a motor includes sensing a temperature within the motor, calculating a rotor magnet temperature from the sensed temperature, and calculating the actual output mechanical torciue from the rotor magnet temperature.

A novel cotton cultivar, designated PM 2168 RR, is disclosed. The invention relates to the seeds of cotton cultivar PM 2168 RR, to the plants of cotton PM 2168 RR and to methods for producing a cotton plant produced by crossing the cultivar PM 2168 RR with itself or another cotton variety. The invention further relates to hybrid cotton seeds and plants produced by crossing the cultivar PM 2168 RR with another cotton cultivar.
摘要:
A blindmate interconnect coaxial connector includes a center conductor, a thermally-conductive dielectric surrounding the center conductor, and an outer tubular conductor surrounding the dielectric. The dielectric transfers heat from the center conductor to the outer conductor, and the outer conductor includes heat transfer fins to radiate such heat. The center conductor is formed by first and second halves which mate within the axial bore of the dielectric. The outer conductor is formed of two mating sections. The center conductor and surrounding dielectric are inserted within the first mating section, and the second mating section is then mated with the first section to complete the assembly of the connector.

A method for maintaining the activity of silicoaluminophosphate (SAPO) molecular sieve catalyst particles during oxygenate to olefin conversion reactions. After regeneration of SAPO catalyst particles, the regenerated particles are mixed with particles having coke on their surface in a manner that maintains their catalytic activity at a predetermined level.
摘要:
The present invention provides various processes for fluidizing molecular sieve catalyst compositions in a fluidized bed reaction system. The invention comprises fluidizing a molecular sieve catalyst composition with a reactive fluidizing medium under conditions effective to convert at least a portion of the fluidizing medium to additional product. The invention is ideally suited for implementation into an oxygenate to olefin reaction system, in which the fluidizing medium optionally comprises byproducts of the oxygenate to olefin conversion reaction.
