The feed surfaces of feed rollers along the paper path of an imaging machine are cleaned by passing a cleaning sheet along the paper path through the imaging machine, the cleaning sheet including a substrate carrying a coating of synthetic polymeric material in a pattern which assures contact between the coating and the feed surfaces to be cleaned, the material of the coating having a tack which enables the coating to pick off particles of unwanted material from the feed surfaces and capture the picked-off particles for movement with the cleaning sheet along the paper path and out of the machine.

Cleaning sheet and method for cleaning paper path feed roller surfaces

A process for preparing a co-poly(amide/peptide) by reacting polymeric or oligomeric polypeptides and polymeric or oligomeric polyamides in the presence of an effective amount of one or more aryl phosphoryl azide compounds.

Process for preparing co-poly(amides/peptides)

A process for preparing polyamides which comprises condensing an aromatic or aliphatic diamine and an aromatic or aliphatic diacid or an amino acid in the presence of one or more aryl phosphoryl azide compounds.

Preparation of polyamide in the presence of aryl phosphoryl azide

A process for forming random copolymers which comprises forming a polymer melt containing one or more polyamides and one or more aryl phosphoryl azide compounds, such as diphenyl phosphoryl azide; and heating said melt for a period of time sufficient to form the desired amount of the copolymer.

Process for production of quasi-random copolymers from homopolymers

A photoactivated time-temperature indicator is based on a leuco base system. A thermally insensitive, white ('inactive') leuco base (or a mixture of such leuco bases) is mixed, preferably in a polymeric matrix, with a material that generates acid upon exposure to light. Photoexcitation, preferably by UV or near UV light, causes the formation of a thermally sensitive, color-forming ('active') product. Following this activation step, a progressive color development occurs at a rate that increases with temperature. The indicator is useful for monitoring the freshness of perishable products, particularly those stored at subambient temperature.

Photoactivatable leuco base time-temperature indicator

A process for decreasing the melt index and increasing the melt viscosity and melt elasticity of polyamide by adding thereto an effective amount of an aryl phosphoryl azide compound as for example diphenyl phosphoryl azide, and thereafter heating the composition until the desired changes in melt index, melt viscosity and melt elasticity are attained.

Process for increasing the melt viscosity and/or melt elasticity of

This invention relates to a process for blow molding polyamide compositions where the molten polyamide includes an effective amount of one or more aryl phosphoryl azide compounds.

Method of blow molding polyamides

An activatable time-temperature indicator consists of an oxygen-sensitive reaction product of a triarylmethane dye and a decolorant that is coated on a substrate and covered by an oxygen barrier. Optinally, an oxygen-permeable layer is between the coating and the oxygen barrier. The indicator is activated by removing the oxygen barrier. Following this activation step, a progressive color development occurs at a rate that increases with temperature. The indicator is useful for monitoring the freshness of perishable products, particularly those stored at sub-ambient temperature.

Activatable time-temperature indicator

A kit and method for detecting lithium ions in a sample. The kit includes a lithium ion selective color indicator which is a leuco precursor of an arylmethane dye dispersed in a matrix. In use, the color indicator is contacted with a sample and any color change therein is monitored. A color change in the indicator indicates the presence of lithium ions in the sample.

Kit and method for detecting lithium ions

A photoactivated time-temperature indicator is based on diacetylenic salts. A thermally unreactive ('inactive') diacetylenic salt (or a mixture of such salts) is mixed, in a polymeric matrix, with a material that generates acid upon exposure to light. Photoexcitation, preferably by UV or near UV light, causes the formation of a thermal reactive ('active') free diacetylenic acid. Following this activation step, a progressive color development occurs at a rate that increases with temperature. The indicator is useful for monitoring the freshness of perishable products, particularly those that require refrigeration.
