Abstract: A method and apparatus for rehabilitating or repairing waste water system components or the like comprising a spray-applied, multi-layer liner which seals the components and imparts structural integrity. The liner comprises a first moisture barrier layer, a foam layer and a second moisture barrier layer. A primer may be applied where desired. Typically, the first and second moisture barrier layers are made of the same material for forming a skin on both sides of the foam layer. The combination of the foam layer and the two moisture barrier layers imparts structural strength and rigidity to the cured liner.

Abstract: A single-step, spray-applied, multi-layer liner seals the components and imparts structural integrity for lining a system component. The multi-layer liner includes an inner or first moisture barrier or skin layer, a foam layer and a second moisture barrier or skin layer. Where desired, a separate primer layer can be applied to wet surfaces and in order to form an enhanced bonding layer between the system component, typically a concrete or cement surface, and the first moisture barrier or skin layer. The first and second moisture barrier layers naturally form a skin on both sides of the internal foam layer. The combination of the foam layer and the two moisture barrier layers imparts structural strength and rigidity to the cured liner.

Abstract: A photon generator incorporates a fiber optic element placed in a magnetic field such as that generated by an electric motor or an electric generator for generating a stream of photons. The fiber optic element is coated with a magnetically reactive material such as mercury or a mercury compound, whereby photons are released when the fiber optic element is placed in the electromagnetic field. The photons may be directed by controlling the cross section of the fiber optic element. A collector may be utilized for collecting the stream of photons for conversion into useable energy.

Abstract: A modular columbarium system comprised of modular niche units each having a plurality of urn niches defined therein, wherein adjacent modular niche units are secured to one utilizing an interlocking system that provides alignment and stabilization of the units. The columbarium system is a modular design which facilitates the easy relocation of the modular niche units and the redesign of the columbarium system. The interlocking system connects the modules of the columbarium system to one another to enable easy expansion of the system without diminishing its stability. The modular niche units can also be used with existing columbarium systems. Memorial plates of various sizes are provided to cover the niche openings such that couples or family members can be grouped together under one memorial plate.

Abstract: A trash receptacle is a frusto-conical container with an open top and open bottom. The bottom is of a greater diameter than the top. A standard plastic bag may be placed in the container with the open top of the bag folded over the open top of the container. A lid is adapted to be placed over the open bag and the top of the container. Handles are provided on the lid and on the container to facilitate handling. The container is adapted to be placed on a base which may be a wheeled cart for mobility. When the bag is to be removed from the container, the container is lifted over the bag using the handles. The bag may then be removed from the base for proper disposal. The container may include a venting system to assure that the bag is easily removable from the container. Clips hold the bag in the container while it is being filled. The clips can be separate from or an integral part of the container.

Abstract: A technique and device for rehabilitating or repairing waste water system components or the like, comprising a spray-applied, multi-layer liner which seals the components and imparts structural integrity. The liner comprises a primer layer, a first moisture barrier layer, a foam layer and a second moisture barrier layer. The first and second moisture barrier layers are preferably made of the same material and form a skin on both sides of the internal foam layer. The combination of the foam layer and the two moisture barrier layers imparts structural strength and rigidity to the cured liner.

Abstract: A method for creating a multiwalled container capable of safely holding a desired liquid. The container may be formed using a mold or form or may be formed on the inside of an existing shell or structure, thereby incorporating the shell or structure as part of the container. The mold or shell is prepared and coated with a first, impermeable polymer layer. An interstitial material is then applied to the first polymer layer and a second impermeable polymer layer is then applied to the permeable, interstitial material. This creates an interstitial space between the two impermeable polymer layers. The process of applying interstitial material and additional polymer layers may be repeated as many times as necessary to achieve the desired number of impermeable walls within the container.

Abstract: This invention relates generally to the field of repair for manholes and other like tubular structures and is more specifically directed to a sectioned panel assembly which is premanufactured for installation within an existing manhole.

Abstract: A single stroke pressure viscous liquid pump for discharging highly viscous and filled, abrasive liquids under pressure sufficient for spray coating a surface with such liquids. The device includes an upright liquid tank having an open upper end positioned atop a base plate of a frame in coaxial alignment spaced directly beneath a pressure cylinder which includes an axially movable ram having a piston at its lower end. The piston is sized to sealingly engage the inner surface of the tank whereby downward axial force generated by the ram is transmitted directly against the upper surface of the liquid within the tank. A discharge outlet near the bottom of the tank is connectable to a conduit and liquid spray nozzle for spray application of the pressurized liquid discharged from the tank outlet. Only a single downstroke of the ram is required at a very slow feed rate to empty the tank of liquid, thus eliminating virtually all heat buildup.
