A fan blade platform is provided. The fan blade platform may include a wall, a first sidewall extending from the flowpath to a circular member, and a second sidewall extending from the flowpath to the circular member. A stiffening member may also extend from the circular member to the flowpath and be formed integrally with the first sidewall, the second sidewall, and the flowpath.

A curable aqueous composition is disclosed comprising a carbohydrate, a crosslinking agent, and an amine base, wherein the curable aqueous composition has a pH adjusted by the amine base. Further disclosed is a method of forming a curable aqueous solution.

A composite material for absorbing forces applied to a face of the material includes a first plurality of shaped solids and a second plurality of shaped solids arranged proximate to one another. A third plurality of shaped solids may be arranged proximate to both the first and second plurality of shaped solids, and be least partially located in a plurality of spaces formed by the arrangement of the first and second shaped solids proximate one another. One of the first, second and third pluralities of solids may be connected to a material layer, which may be a fiber or filament reinforced layer. Interstices existing between the first, second and third pluralities of shaped solids may have a resilient material therein.

In one aspect, a seal case is provided for a roller bearing assembly having a central axis. The seal case includes an annular first end section including a rim configured to engage an outer ring, an intermediate section including a radial wall extending inwardly from the first end section and an axial wall extending axially away from the radial wall and the first end section, and an annular second end section extending radially inward from the axial wall of the intermediate section. The seal case further includes an insert of the first end section made of a first material. The first end section and the radial wall of the intermediate section include a second material joined to the insert. The first material of the insert may be selected to provide improved durability and/or to resist expansion and contraction of the first end section caused by changes in temperature.

Lightweight, structurally reinforced thermoplastic objects comprising at least one reinforcement zone are manufactured by providing a heatable rigid forming chamber with a chamber volume. At a temperature below the thermoplastic softening temperature, the chamber is loaded with a plurality of thermoplastic lofting bodies and a plurality of thermoplastic reinforcement bodies wherein the lofting bodies are heat-loftable bodies comprising a thermoplastic matrix containing an elastically compressed assembly of reinforcement fibers embedded therein, lofty non-woven bodies comprising an elastically compressible assembly of reinforcement fibers and thermoplastic fibers. Upon closing the chamber, lofting bodies of lofty non-wovens are elastically compressed, producing an internal pressure. After heating the chamber above softening temperature, reinforcement bodies and lofting bodies are ow thermoplastically formable, and lofting bodies configured as heat-loftable bodies produce a second internal pressure. After a predetermined processing time, the chamber is cooled yielding a structurally reinforced object.

By providing a mountain-shaped mountain portion (5a) protruded from a surface of a plunger (5) facing a valve seat to the inside of a rubber member (8), a dimensional change amount of a valve seat abutting portion (8a) in an opening and closing direction decreases, and thus it is possible to suppress change in characteristic. Also, it is possible to secure a rubber deformation amount sufficient for absorbing impact when the valve seat abutting portion (8a) collides with the valve seat, thereby suppressing an operation sound.

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.
