Abstract: An exhaust system having a pipe for conveying exhaust from an engine, the end of which has an outwardly-protruding lip; a first pipe flange having a hole large enough to allow the lipped end of the pipe to pass through it, and a recessed shoulder adjacent the hole; a collar, configured to releasably encircle said first pipe, to abut with the recessed shoulder at its outer periphery, and the lipped end of the pipe at its inner periphery, thereby preventing the collar and lipped pipe assembly from passing through said hole; and a second pipe flange configured to attach to said first pipe flange to connect a tail pipe to the first pipe, and to hold the pipe, flange and collar assembly together. The invention also provides counterweights for counterweighted lift trucks adapted to secure such exhaust systems, and methods of fitting such exhaust systems.

Abstract: An improved yurt assembly for facilitating easy yurt installation and increasing stability, comprising a plurality of expandable lattice wall sections, vertical posts and roof poles. Each lattice wall section includes a plurality of pivotally connected link members. Each of the vertical posts includes a groove on its top end for receiving one of the roof poles, a first slot near its top end, a second slot near its bottom end, and a plurality of intermediate slots between the first and second slots. The first and second and intermediate slots are adapted to receive topmost, bottommost and intermediate corners of the lattice wall sections. The corners of two adjacent lattice wall sections are received into each side of the slots of a vertical post, which maintains the height of the lattice and secures the wall sections during assembly.

Abstract: A snow scoop having a pair of wheels for support and an adjustable scoop angle. The scoop portion is foldable for easy storage when the device is not in use. Said scoop portion is adapted for attachment to a standard hand truck thereby converting the same into a wheel born snow scoop.
