Abstract: A retractable adjustable-trajectory rooftop fire sprinkler comprising a base component, a lockable flow-through hinge fitting, a trajectory angle setting mechanism, and a sprinkler head. Trajectory angle setting mechanism is a mechanism to adjust, lock, and hold a certain trajectory angle of water flowing from the sprinkler head by allowing the rotation of the lockable flow-through hinge fitting about an axis-of-rotation relative to the base component. Base component and lockable flow-through hinge fitting each further comprise at least one knuckle protrusion with a hinge screw hole located therein. All hinge screw holes are aligned and a hinge pin or a hinge screw is inserted through each hinge screw hole to pivotally attach lockable flow-through hinge fitting to base component. Trajectory angle setting mechanism includes a lockable hinge mechanism, a spring pin and plurality of spring pin holes, and a ratchet mechanism.

Abstract: A sprinkler system includes a base having a watertight backing material, adapted to attach to a roof; a sprinkler head attached to the base; a coupling adapted to attach a water hose to the sprinkler head; a securing mechanism adapted to attach the sprinkler to the roof; and a cover to protect the sprinkler head when the sprinkler is not in use. The sprinkler may be adjusted directionally to have a directional stream or spray of water of varying degrees of 360 degree coverage.

Abstract: An improved polishing composition is provided that includes an emulsion of a oil-based components and water-based components and a water soluble polishing agent. The polishing composition of the present invention is rubbed on a painted surface, hosed off with water and wiped or towel dried. Because of the use of a water soluble polishing agent in the polishing composition, all or substantially all of the polishing agent is washed away with the water. This eliminates the need for a two-step polishing process wherein a polishing composition is applied to a surface and allowed to dry in a first step and the surface is buffed with a dry cloth in a second step. One preferred embodiment of the present invention includes silicones, water, a nonionic or anionic surfactant and a water soluble polishing agent. Optionally, the polishing composition may include a solvent, mineral oil, wax, and a preservative.

Abstract: A non-aqueous, cleaner/polish composition that is substantially visually clear and contains a microparticulate, amorphous pyrogenic silica as a mildly abrasive polishing and thickening agent, a film-forming agent, a film plasticizer, a volatile silicone gloss agent, and aliphatic solvent cleaning agents.
