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 gear case seal is provided for use with a traction motor. The seal may have an arcuate body with an outer annular layer forming a centrally located channel extending along its length, and an inner annular layer bonded to the outer annular layer along opposing axial edges so as to close off the centrally located channel. The body may also have a middle layer disposed within the centrally located channel and made from a material different than a material of the inner and outer layers.

A trench-shoring sheeting panel includes a rectangular-shaped polyethylene sheet having opposing primary surfaces and four corners, a planar support structure embedded in the polyethylene sheet, a plurality of hand hold apertures formed in the polyethylene sheet, a plurality of corner holes positioned adjacent to the four corners, and a plurality of protrusions positioned on at least one of the primary surfaces.

The invention relates to a process for manufacturing a textile preform from a fibrous array with continuous fibres, the process comprising a step for heating of the fibrous array between a matrix and a punch to stiffen this fibrous array. To cut down processing time, the heating step is performed by having a hot gas flow circulate through the matrix, the fibrous array and the punch.
