Abstract: In an embodiment of the invention, a dripless air conditioning (A/C) vent includes a vent diffuser in communication with an A/C vent. The vent diffuser includes a pair of end cap components fabricated from poly-vinyl chloride (PVC) and a pair of side channel rails also fabricated from PVC and arranged oppositely to one another, each side channel rail secured at each distal end to a corresponding one of the end cap components. The vent diffuser further includes at least one inside channel rail also fabricated from PVC and secured at each distal end to a corresponding one of the end cap components at a position intermediate to where each side channel rail is secured and a middle cap arranged perpendicularly to each of the channel rails and secured to a common bottom face of each of the channel rails.

Abstract: A corrosion inhibiting composition includes, by weight, 2% to 20% alkali metal nitrite or alkaline earth metal nitrite, 16% to 90% alkali metal benzoate or alkaline earth metal benzoate and 4% to 50% alkali metal molybdate or alkaline earth metal molybdate. The composition is mixed with a resin carrier to form a master batch. A plastic composition containing a corrosion inhibiting component and a resin is also provided wherein the corrosion inhibiting component includes 0.13% to 1.25% alkali metal nitrite or alkaline earth metal nitrite, 1% to 5.63% alkali metal benzoate or alkaline earth metal benzoate and 0.25% to 3.13% alkali metal molybdate or alkaline earth metal molybdate by weight of the plastic composition. The plastic composition can be formed into a film which can be used to cover metal articles thereby preventing corrosion.
