Abstract: A telescopic support tower has a plurality of tubes nested or stacked with one another. A base is coupled with the outermost tube to stand the plurality of tubes transverse to the base. A mechanism is provided in the base to enable access to an interior space of the plurality of tubes. The mechanism is coupled with a source of compressed air. A plurality of seals, at least two, are positioned on each of the adjacent tubes to seal the tubes with respect to one another. The plurality of seals enables sealed sliding movements of the tubes with respect to one another. At least one first clamp is provided to prohibit movement of selected tubes of the plurality of tubes such that only one tube of the plurality of tubes is enabled to telescope at a time. At least one second clamp fixes the selected telescoping tube to an adjacent tube of the plurality of tubes.

Abstract: A trailer includes a convertible handle having a handle portion, the handle portion pivotally attached to a tongue portion, the handle portion having a first gripping portion end and a second clevis end and an intermediate pivot, the handle portion being pivotably shiftable about the pivot between a first disposition presenting the gripping portion end proximate an end of the tongue portion and a second disposition presenting the clevis end proximate the end of the tongue portion. A method of operating a trailer is further included.

Abstract: A ladder includes a first ladder section; a second ladder section removably attachable to the first ladder section by means of a hinge; and an adjustable hinge mechanism and a non-adjustable static hinge mechanism, both hinge mechanisms being selectively attachable to the ladder sections for affixing first and second ladder sections together at an angle in selectably varying configurations, the adjustable hinge mechanism being angularly adjustable, the static hinge mechanism presenting a fixed angle. A method of forming such ladder is further included.

Abstract: A process for forming a multilayer composite coating on a substrate is provided. The process includes forming an electrodeposition coating layer on the substrate by electrodeposition of a curable electrodepositable coating composition over at least a portion of the substrate. Optionally, the coated substrate is heated to a temperature and for a time sufficient to cure the electrodeposition coating layer. A basecoating layer is formed on the electrodeposition coating layer by depositing an aqueous curable basecoating composition directly onto at least a portion of the electrodeposition coating layer. Optionally, the basecoating layer is dehydrated. A top coating layer is formed on the basecoating layer by depositing a curable top coating composition which is substantially pigment-free directly onto at least a portion of the basecoating layer. The top coating layer, the basecoating layer, and, optionally, the electrodeposition coating layer are cured simultaneously.

Abstract: A clear coating composition for use over a colored basecoat having improved scratch resistance is disclosed. The coating composition comprises a film-forming polymer and a curing agent.
