摘要:
Disclosed painted roof coverings and related methods of manufacturing such painted roof coverings that use a color coating over the roof coverings instead of embedded pre-colored rock granules on the exposed surface of the roof coverings. By painting a roof covering with a color coating, any kind of top surfacing material, such as rock, plastic, mineral, man-made, or organic granules, may be used in place of the pre-colored rock granules. In some embodiments, it is desirable to size the top surfacing material to provide adequate UV protection and coverage to the weatherproofing asphalt material located below the top surfacing material. Further, the color of the shingles may be accurately matched between batches of shingles, between manufacturing facilities, and even between manufacturers. In addition, designs may be painted on the surface of the roof covering, which was previously impossible using pre-colored granules.
摘要:
The present invention relates to a non-flammable, anti-corrosive, non-discoloring product which has both penetrating and lubricating characteristics and is prepared with a non-flammable propellant that does not emit volatile organic compounds, but does replace water, and to a process for producing the same.
摘要:
A product for inflating a pneumatic tire including an enhanced delivery system is disclosed according to the present invention. The tire inflating product includes a container containing a condensed gas and a sealant, and a flexible conduit extending outwardly from a first end of the container in a direction parallel to the longitudinal axis of the container. The free end of the conduit is adapted to be connected to a valve stem of a tire and, typically, includes a threaded coupling with a valve depressor. The container includes a valve assembly on one end for releasing the contents of the container and an actuator is provided for actuating the valve assembly to release the container contents through the conduit.
摘要:
A combined cap and nozzle for a container is provided, having a skirt, a transverse wall, and having a restricted orifice of small diameter through the wall. A coupling is provided, being preferably standard female threads as used in garden hoses, for attachment with a conduit such as with the male coupling of a garden hose. Water from a residential faucet may be passed through the garden hose and the restricted orifice to impact on and dislodge waste from a body.
摘要:
A new tire sealant and inflator composition is provided, which combines a sealant in an aqueous carrier with a non-flammable, non-ozone depleting propellant/inflator. A preferred composition combines a sealant composition with 1,1,1,2-tetrafluoroethane (134a). In a preferred embodiment, a vapor pressure depressant is combined with the sealant and 134a. A preferred sealant and inflator composition comprises from about 20% to about 80% of 134a, from about 2% to about 10% of a sealer, such as latex, or a polyvinyl acetate emulsion; from about 1% to about 8% of a freezing point depressant, such as an alkylene glycol; from about 0.1% to about 1% of a corrosion inhibitor, such as ammonia; from about 30% to about 70% of a carrier, such as water; and from about 4% to about 40% of a vapor pressure depressant, such as a glycol ether. A preferred vapor pressure depressant is 2-butoxyethanol, and a preferred freezing point depressant is ethylene glycol. Preferably the sealant composition combine with 134a or other non-flammable and non-ozone depleting propellant/inflator is biodegradable.
