A table drive system for driving a support table is disclosed herein. The table drive system comprises at least one of a first drive assembly or a second drive assembly or a combination thereof. The first drive assembly is configured for moving the support table in a first direction for example, a longitudinal direction and the second drive assembly is configured for moving the support table in a second direction for example, a vertical direction. The table drive system further includes a safety block in combination with at least one of the first drive assembly or the second drive assembly, the safety block configured to arrest the motion of the first drive assembly or the second drive assembly upon experiencing a predetermined condition such as the failure of at least one of the first drive assembly or the second drive assembly.

Table drive system

A method is disclosed to purify a polymeric material by filtering a melt comprising poly(arylene ether) and poly(alkenyl aromatic) through a melt filtration system. The method provides a filtered polymeric composition having reduced levels of particulate impurities. The filtered polymeric composition prepared is suitable for use in data storage media applications.

Purified polymeric materials and methods of purifying polymeric materials

An alkylation method comprises reacting a hydroxy aromatic compound with an alkyl alcohol in the presence of an alkylation catalyst comprising a metal oxide wherein the alkylation catalyst, has a surface area to volume ratio of about 950 to about 4,000 m/m, an aspect ratio of about 0.7 to about 1.0 or a combination of the foregoing.

Method for making alkylated phenols

An alkylation catalyst comprises a metal oxide wherein the catalyst has a surface area to volume ratio of about 950 m/mto about 4000 m/m.

Alkylation catalyst and method for making alkylated phenols

A metal oxide catalyst precursor composition comprises a pore former and a catalyst reagent.

Catalyst and method for the alkylation of hydroxyaromatic compounds

A method of preparing a poly(arylene ether) includes oxidatively polymerizing a monohydric phenol in solution, concentrating the solution by removing a portion of the solvent to form a concentrated solution having a cloud point, T , adjusting the temperature of the concentrated solution to at least about (T &deg; C.), and combining the concentrated solution with an anti-solvent to precipitate the poly (arylene ether). The method reduces the formation of undesirably fine particles in the product poly(arylene ether).

Method of preparing a poly(arylene ether), and a poly(arylene ether) prepared thereby

A method of preparing a poly(arylene ether) includes oxidatively coupling a monohydric phenol in a reaction solution at a reaction temperature that exceeds the cloud point temperature of the reaction solution. The oxidative coupling occurs in the presence of a metal complex catalyst, and when the catalyst includes an amine ligand, the method facilitates incorporation of the amine ligand into the poly(arylene ether) resin. The amine-incorporated poly(arylene ether) resins prepared by the method are useful in the preparation of higher molecular weight poly(arylene ether) resins and compatibilized blends of poly(arylene ether) resins with other thermoplastics.

Method of preparing a poly (arylene ether) and a poly (arylene ether) prepared thereby

A method of preparing a poly(arylene ether) includes oxidatively polymerizing a monohydric phenol in solution, concentrating the solution by removing a portion of the solvent to form a concentrated solution having a cloud point, T , and combining the concentrated solution with an anti-solvent to precipitate the poly (arylene ether), wherein the concentrated solution has a temperature of at least about (T &minus;10&deg; C.) immediately before it is combined with the anti-solvent. The method reduces the formation of undesirably fine particles in the product poly(arylene ether).
