Abstract: Self-propelled, self-powered, propulsion devices as part of pipe lining system adapted to create an internal liner member on a pipe or other tubular structure, the system being the combination of a sprayer apparatus, an umbilical member connected to the sprayer apparatus, wherein the umbilical member supplies no power or communications to the propulsion devices, and a plurality of propulsion devices mounted externally onto the umbilical member in a removable manner. The spraying apparatus and propulsion devices are independently powered and controlled such that each may be accelerated or decelerated as required to maintain the sprayer apparatus at a constant speed during the application process.

Abstract: An autonomous device for the vaporization and dispersal of a sanitizing agent adapted for the use in closed structures such as rooms, vehicles, trash bins, dumpsters, and other containers.

Abstract: A pipe lining having at least two material layers, a first elastomeric layer spray applied directly to the inside of a pipe which acts as a hydrophobic, ductile membrane, and a second rigid layer is spray applied to the first layer prior to complete curing of the first layer. One or more additional layers may be applied to the second layer to provide additional abrasion, erosion or chemical resistance to the second layer. An intermediate reinforcing layer may be disposed between the first and second layers. The first layer cures into a closed cell elastomeric foam, such that stress and other forces are not passed from the pipe to the rigid second layer.

Abstract: A taping apparatus adapted to apply tape over voids on an interior pipe wall, the taping apparatus having a transport assembly adapted to move the apparatus through a pipe; and a rotatable taping assembly adapted to retain a roll of tape and apply the tape over a void on the interior wall of the pipe, the taping assembly comprising an extendable and tractable arm assembly and a tape applicator assembly.

Abstract: A pipe lining apparatus transport assembly having one or more positioning mechanisms for maintaining the orbiting operational components of the pipe lining apparatus in a concentric relationship with the pipe, the positioning mechanisms including alone or in combination extension/retraction mechanisms, track set rotational mechanisms, articulating joint mechanisms and/or linear translation mechanisms.

Abstract: A material casting assembly for a pipe lining apparatus, the assembly having a housing mounted onto an extension/retraction arm and containing an impingement block controlled by an impingement valve, and a static auger bounded by a rotating cylinder which defines a mixing path to an extrusion chamber. The rotating cylinder has exit ports through which lining material is expelled from the extrusion chamber onto a pipe wall.

Abstract: A pipe lining apparatus having a pressure sensitive adhesive backed reinforcement filament that is helically wound onto the inner surface of a pipe or pipe lining by an inverted filament winding apparatus, the apparatus having multiple spools and applicator arms to retain and apply the filament. The applicator arms may be aligned circumferentially or axially.

Abstract: A method and device for measuring the thickness of a liner applied onto the inner wall of a pipe, the device comprising a sprayer assembly adapted to deposit a polymer resin onto the inner wall of a pipe to create a liner upon curing, the sprayer assembly being moved through the pipe. The sprayer assembly has a leading sensor assembly that measures the inner diameter of the pipe and trailing sensor assembly that measures the inner diameter of the liner. The trailing sensor assembly has a housing with windows through which sensor devices take readings, and a transparent film is disposed across the windows to protect the sensors from occluding contamination. The transparent film is advanced as the exposed portion of the film becomes excessively contaminated.

Abstract: A pipe lining apparatus having a resin-impregnated reinforcement filament that is helically wound onto the inner surface of a tubular first lining layer disposed within a pipe by an inverted filament winding apparatus, the apparatus having a spring-loaded, articulated frame which maintains an orbiting applicator assembly.
