Abstract: The present invention relates to a preservative formulation for use in treating wood or other cellulosic materials, said formulation comprising: at least one biocidal metal compound; at least one preservative; and an aqueous carrier, wherein the preservative formulation has an uptake in the sapwood of less than about 220 l/m3 yet achieves substantially full penetration of the sapwood. Preferably, the preservative formulation is copper/tebuconazole in a ratio of about 25/1 w/w; and the wood is around 25 mm in thickness—for instance, decking timber.

Abstract: A hydraulic tail trailer comprising a main deck having a main tail assembly pivotally connected to the rearward end thereof with the pivotal connection therebetween being located forwardly of the centerline of the rear axle of the trailer suspension system. The location of the hinge between the main deck and the main tail assembly, by being located forwardly of the centerline of the rear axle, provides a main tail having an increased length thereby providing a lower loading angle without increasing the overall length of the trailer. The forward end of the main deck is pivotally connected to the rearward end of an upper deck so that the main deck may be raised which further reduces the angle between the rearward end of the main deck and the forward end of the main tail for loading and unloading purposes.

Abstract: The invention is drawn to a gasket (34) for use in an individual fuel cell (20). The gasket (34) includes at lest one generally rigid bridge (44) or (46) that extends across the fluid flow channels in adjacent separator plates (38) and (40). The bridge (44) or (46) assures that the fluid flow channels are not blocked or restricted in the cell (20). Each bridge (44) or (46) may be integral with its corresponding gasket (34). The gasket (34) may be a multi-piece gasket with a carrier material having an elastrometric seal portion (74) secured to it.

Abstract: The elastomeric static gasket is disclosed where a thin carrier is used to support a stopper member and an elastomeric seal member on the same surface of the carrier. An elastomeric seal is molded adjacent to the stopper. The stopper member acts as a compression limiter to limit the compressive forces on the seal. Preferably the stopper is an elastomer. Alternatively, the seal can be made with a different material than the stopper member. A variety of carrier members may be used in practicing the invention.
