Abstract:
Modified copolyesters having relatively low refractive indices and relatively high glass transition temperatures are disclosed. These modified copolyesters can be used in forming one or more layers in an optical film, such as a multilayer polymer film.
Abstract:
Substrate films, thermal mass transfer donor elements, and methods of making and using the same are provided. In some embodiments, such substrate films and donor elements include at least two dyads, wherein each dyad includes an absorbing first layer and an essentially non-absorbing second layer. Also provided are methods of making a donor element that includes an essentially non-absorbing substrate, an absorbing first layer, and a non-absorbing second layer, wherein the composition of the essentially non-absorbing substrate is essentially the same as the composition of the essentially non-absorbing second layer.
Abstract:
An air bag module (12) includes an inflator (18) that is actuatable to supply inflation fluid to inflate an inflatable vehicle occupant protection device (16). A housing (14) directs the inflation fluid from the inflator (18) toward the inflatable device (16). At least one vent opening (40) is formed in the housing (14) for selectively venting inflation fluid from the housing. A door panel (70) is movable between a closed position blocking venting of inflation fluid from the housing (14) and an open position enabling venting of inflation fluid from the housing. The door panel (70), when in the closed position, is biased toward the open position. In one embodiment, the door panel (70) is resiliently deformable. In another embodiment, a spring (71a) is connected with a door (70a) and biases the door toward the open position.
Abstract:
An inflator for inflating a vehicle occupant restraint, such as an air bag, includes a container (18) having a stored mixture of gases including a primary gas for inflating the air bag and a combustible gas. An actuator assembly (20) opens the container (18) and ignites the combustible gas as it flows toward the vehicle occupant restraint. Igniting the combustible gas creates a combustion reaction external to the container (18) which heats the primary gas as it flows toward the air bag. A combustion arrestor (22) minimizes the propagation of the combustion reaction into the container (18).
Abstract:
A safety apparatus includes an air bag 32 which is inflatable to an extended condition disposed between a hip 38 of a person 12 seated on a vehicle seat 14 and a door 16 of the vehicle. An inflator assembly 22 provides gas to inflate the air bag. The inflator assembly 22 and the air bag 32 are mounted on the vehicle seat 14 for movement with the vehicle seat relative to the body of the vehicle.
Abstract:
A source of gas for inflating a vehicle occupant restraint comprises a container. Gas generating material in said container comprises an alkali metal azide and a metal oxidizer. When ignited, the gas generating material produces heated nitrogen gas. A supply of pressurized nitrogen gas is also in the container. Structure is provided for separating the supply of pressurized nitrogen gas from the gas generating material. The separating structure is releasable to enable the heated nitrogen gas and the stored nitrogen gas to commingle. The source of gas also includes structure for directing the stored nitrogen gas and the heated nitrogen gas through a tortuous path toward the vehicle occupant restraint so as to remove particulates from the gases.
Abstract:
A lightweight composite launcher pod which includes a multiplicity of eloted launcher tubes that are accurately aligned in a composite material with the composite material having four outer sides with alignment surfaces on three of the sides and bearing and alignment surfaces on the other side, and the lightweight composite launcher pod being capable of serving as the shipping and storage container for rockets before launching of the rockets as well as for launching the rockets therefrom when mounted in a launcher structure.
Abstract:
A method of making a rocket motor case with an integral nozzle in which the rocket motor has a large length to diameter ratio and is made by applying a linear wrap of fibers as a first layer on a mandrel and then by applying radial wraps over said linear wrap and also conforming the linear fibers to the shape of the nozzle after applying the linear fibers on said mandrel to provide a structure that has sufficient stiffness to accomplish the desired result of a large length to diameter rocket motor case.
Abstract:
Optical bodies are disclosed that include a first optical film, a second optical film and at least one rough strippable boundary layer disposed between the first and second optical films. Also disclosed are optical bodies including a strippable boundary layer disposed between the first and second optical films and including a first polymer and a second polymer that is substantially immiscible in the first polymer. The present disclosure also provides methods of processing optical bodies that include stretching the optical bodies.
