A corrosion inhibiting polyalkylenepolyamine composition comprising a mixture of

Polyalkylenepolyamines as corrosion inhibitors

A hydrocarbon-soluble corrosion inhibitor composition comprising the reaction product obtained by the acid-catalyzed oligomerization of an alkylaniline and formaldehyde, wherein the alkylaniline has from 4 to 30 carbon atoms in the alkyl substituent. Also disclosed is a method of inhibiting corrosion of a corrodible metal utilizing said composition.

Alkylaniline/formaldehyde oligomers as corrosion inhibitors

A hydrocarbon-soluble corrosion inhibitor composition comprising the reaction product obtained by the acid-catalyzed oligomerization of alkylaniline, formaldehyde, and an aromatic compound selected from aniline, phenol, alkylphenol and an ethoxylated alkylphenol. Also disclosed is a method of inhibiting corrosion of a corrodible metal utilizing said composition.

Alkylaniline/formaldehyde co-oligomers as corrosion inhibitors

Tractable doped electroactive polymers, comprising recurring units of a 3,3'-N,N'-disubstituted-6,6'-bicarbazole-1,3,4-oxadiazole-2,5-diyl ring system, and a sufficient concentration of a charge-compensating ionic dopant associated therewith.

Bicarbazole-oxadiazole electroactive polymers

An electrochromic device which incorporates a reversibly color-changing organic polymer film as the display electrode. The display polymer film is capable of undergoing reversible oxidation and/or reduction to a charged, colored, conductive state. Upon reversing the charge, the polymer returns to its virgin color. The display films are comprised of linear fused heterocyclic ring systems, optionally with connecting units, or linear monocyclic ring systems and connecting units. The device requires low currents to operate and switch from the virgin state to the colored state. It also can optionally be operated to exhibit several colors.

Electrochromic devices

Tractable doped electroactive polymers, comprising recurring units of a 3,6-N-substituted carbazole-1,3,4-oxadiazole-2,5-diyl ring system, and a sufficient concentration of a charge-compensating ionic dopant associated therewith.

Carbazole-oxadiazole electroactive polymers

The present invention is a positive damper adjustment to be used in conjunction with a conventional fireplace which is provided with a flue damper controlled by a pivotally mounted handle wherein a handle grasping bracket is threadably mounted on an elongated threaded member disposed rotatably in a fireplace bracket provided with mounting means pivotally mounted to the frame of the fireplace and a handle operably mounted on said elongated threaded member.
