Abstract: A marking composition for placing a temporarily visible mark on a surface. The composition includes a paint base and a pigmented colorant. The pigmented colorant is dispersed within the paint base, and has characteristics that cause the mark to progressively become substantially invisible upon exposure to UV light. Additives, such as UV absorbers and anti-oxidants may be included to alter the rate at which the mark becomes invisible. The pigmented colorant may be a dispersion of dyed melamine-toluenesulfonamide-formaldehyde polymer in a mixture of alkyl based resins and aliphatic hydrocarbons. The colorant may be about 2 to 30 parts by weight of the composition.

Abstract: An aerosol can having two terminal portions each with its own valve and product delivery head of various configurations is disclosed. The can may feature either one or two products for delivery, and can employ one or two volumes of propellant. The material to be delivered can be stored directly in the can or in one or two pouches, or in a combination mode of within the can directly and in one pouch, as may be desired. The same material can also be distributed in two different manners, such as fine mist or strong stream, the mode of delivery being spray head dependent.

Abstract: A reusable high efficiency propellant driven apparatus for the dispensing of liquid products, featuring a refillable product container, and a rechargeable propellant housing. The propellant housing may be moved from container to container, to dispense a plurality of products; and a non-completely dispensed container can have the product exhausted by the replacement of a spent propellant housing, with the same or a different housing that does contain propellant. The housing is disposed concentric to the container and preferably both are secured to a single cap. A dual piston construction is employed to provide a hermetically sealed propellant housing. Product and propellant deployment is controlled by the movement of a pair of gaskets.

Abstract: A liquified petroleum gas (LP gas) can recycling apparatus which includes a first compacting portion which safely evacuates the can for recovery of any residual gaseous product therefrom, then compacts the can, discharges the slug now compacted for collection; and a second gas treatment portion which collects the residual gas, repressurizes it and stores it in a repressurized gaseous state. The apparatus is preferably operated in an automated fashion by compressed air.

Abstract: An aerosol can compacting apparatus which evacuates the can for recovery of any residual propellant and product, therefrom and then compacts the can discharges the slug now compacted for collection. The apparatus can be operated in an automated fashion and preferably by compressed air.

Abstract: A system for recovering propellant from aerosol cans and other sources having a gaseous propellant therein, which system constitutes a separation tank in which the propellant is separated from the product it was to deliver, a compressor to both compress the propellant and introduce it into a heat exchanger which cools the propellant into a liquid which liquid can be collected in a collection chamber in communication therewith.

Abstract: An improved water based aerosol paint is particularly well-suited for use in site marking applications. Its high content of calcium carbonate provides a support for the pigment and resin film. A straight chain, low molecular weight hydrocarbon with between 5 and 8 carbons is used to control foaming.

Abstract: A versatile manually operated striping device has a wheeled base and a handle for pushing the base. The base is in a block Y configuration which provide a U-shaped front end. The front wheels are mounted on separate axles that are extra long. A disk shaped mask is attached to the inboard side of each axle. For normal striping, a can tower is mounted on a moveable mounting bracket that is positioned so that the center of the bottom of the can tower is centrally located in said U-shaped front end. An aerosol spray can inserted in the can tower then sprays, the paint between the legs of the U to provide the normal working, when an actuator is activated. The moveable mounting bracket can be relocated to permit spraying behind the central transverse portion of the base or to the side. The mounting bracket includes a pluralty of holes in a vertical line that fit mounting studs that are attached to one side and to the rear of the can tower.
