Abstract: A means to engage two vertical pipes or tubes of unlike and increasing size that have been co-inserted such as with a roof or floor drain, in a manner that prevents the contained fluid from overspilling when the said pipes become full or when the fluid flows in a direction opposite from normal gravity flow, which is generally considered as flow from the smaller to the larger pipe. The means of engagement closes the void between the inside diameter larger pipe and outside diameter smaller pipe to withstand fluid pressure in a way that accounts for angular misalignment, pipe or tube eccentricity, manufacturing tolerance, as well as tube condition and debris attached to either pipe sidewall. More specifically, a roof drain system for existing roofs or new construction including a flanged outlet pipe for insertion into the roof drain pipe with the flange mounted on top of the roof. A water straining system is mounted on top of the flange.

Abstract: A telescopic manhole or storm drain installation includes a riser assembly provided with an upper section and adjacent lower section the former of which comprises a side wall defining an inverted frustoconical configuration while the latter provides a vertically disposed member having external threads cooperating with a stationary threaded collar. To prepare for resurfacing of a roadway or the like, no excavation about the riser is required prior to its elevation by use of a tool which engages mating receptors located within the interior of the riser. Rotation of the tool rotates the riser assembly within the threads of the collar until the new, elevated plane is achieved. The effort required to displace the riser is minimial due to the movement of its outer surface away from any grouting or roadway base previously abutting the riser. Risers with non-circular upper sections and lids are accommodated by forming the riser of separate upper and lower sections having a sliding joint structure therebetween.

Abstract: The pass-through roof pipe seal system includes an adapter in the form of an inverted funnel with a vertical upper tube and integral lower flared skirt defining a central cavity through which a coolant pipe from a roof air-conditioning unit or the like passes.

The funnel skirt flares out over the lower edge of the cut-away portion of the invention and thus protects it from moisture and also overlies an inverted funnel-shaped vent cup having an upper vertical tube and lower skirt. The vent cup tube is adhered to the outside of the insulation layer around the coolant pipe below the adapter and is protected by the adapter skirt. The vent cup overlies the roof hole of a building upon which an air-conditioning unit is installed and prevents moisture from entering the building.
