Abstract: A method of treating a component adapted for use in a gas turbine engine is described herein. The component may comprise ceramic matrix composite materials. The treatment to the ceramic matrix composite component may reduce or eliminate the wear or damage of crack propagation in the ceramic matrix composite component.

Abstract: The invention concerns a knockdown cabinet, made from sheet metal material, having sufficient rigidity and strength to be used for storing goods and mounted on a base. The knockdown cabinet has a base and a top defining channels which in the assembled condition locate as a close fit around the top and bottom edges of the back and sides to retain the parts together without the use of screws or other fasteners. The base is mounted on wheels. An inverted U-shaped front frame member supports hinges for doors.

Abstract: The invention concerns a trolley comprising a trolley top supportable on a foldable trolley base, for transporting heavy objects particularly between a first support surface and a vehicle and then from the vehicle to a further support surface. The base is foldable between an erected condition in which the sides are spaced apart and upright portions project upwardly from support portions and a folded condition in which the sides are juxtaposed and the upright and support portions lie adjacent one another.In the erected condition a locking pin, at each side, carried by the support portion projects into an aperture in the base of an upright portion to lock the two portions together. When the sides are moved to their juxtaposed positions a release pin attached to the locking pin causes withdrawal of the locking pin from the aperture to allow the upright and support portions to be relatively pivoted to the folded condition.
