A vehicle cabin air filter apparatus for dehumidifying air within its vicinity prior to filtering particulates from air that flows through it along the normal path of flow from the HVAC system into the vehicle passenger cabin.

Cabin air filtering and dehumidifying apparatus

A catalyst composition for the preparation of oligomeric and/or polymer derivatives of olefin monomers, said composition comprising a Group 6 metal amide complex, a Group 1, 2, 12, 13, or 14 metal hydrocarbyl composition or compound, and a solid support comprising aluminum phosphate.

Aluminum phosphate-supported group 6 metal amide catalysts for oligomerization of ethylene

In the apparatus of this invention, filtered electrolyte is introduced immediately adjacent to the revolving cathode head of the apparatus and the filtered electrolyte is forced to flow along the surface of the cathode head to the surface of the bath, thereby flushing foreign materials from the cathode head and the part being replicated. A side weir is provided which is positioned normal to the plane of rotation of the revolvable cathode head which assists in drawing the electrolyte contaminated with foreign materials away from the electroforming section so that the contaminated electrolyte can be more effectively filtered and reused.

Electroforming apparatus for use in matrixing of record molding parts

An improved method is provided for the manufacture of records, molds, and stampers in which the matrix on which the molds and stampers are electroformed is subjected to demagnetization prior to electroforming to prevent tramp metal particles from adhering to the surface of the matrix and thereby causing microdefects in the electroformed parts.
