The invention describes methods for the production of a high purity aluminum salt solution via electrodialysis, and ultimately, the conversion of the high purity aluminum salt to high purity aluminum oxide.

High purity aluminum oxide via electrodialysis

Embodiments of the present invention generally relate to a drawer lifting mechanism, and more particularly to a mechanism that is adapted to bring stored items that are disposed on a supporting surface of a drawer lifting mechanism to a user. The drawer lifting mechanism may be actuated by human power or by use of one or more actuators. In some configurations, the drawer lifting mechanism is disposed and used in the kitchen to enable the delivery of the contents of a kitchen cabinet to a user that is disposed proximate to the cabinet.

The invention describes processes for the production of basic aluminum compounds, including aluminum chlorohydrate, basic zirconium compounds, and basic aluminum zirconium compounds. The process produces products of a wide range of basicities. The products formed by the present invention are comprised of low molecular weight species characteristic of enhanced efficacy antiperspirant salt compositions. The products of this process are suitable for use as water purification agents, as binders in catalyst applications, and in antiperspirant applications. In addition, the invention is directed to the products made by the disclosed process.

Polymetal hydroxychloride processes and compositions: enhanced efficacy antiperspirant salt compositions

The invention relates generally to processes for the production of high-basicity and ultra-high basicity polyaluminum chlorides including aluminum chlorohydrate. The processes can produce products of a wide range of basicities and are particularly useful in producing high basicity products. The process can produce a wide range of solution concentrations and are particularly useful in producing high solution concentrations. The processes described generate high purity products, which are free of by-product salt(s). The processes described herein can also be utilized to produce enhanced efficacy polyaluminum chlorides including aluminum chlorohydrate. When compared to conventional processes for manufacturing these compounds the processes disclosed herein are unique in so far as the disclosed processes do not require aluminum metal as a starting material. The products of the processes are suitable in applications including water purification, catalysts, and antiperspirants. In addition, the invention is directed to the products prepared by the processes described herein.

Polyaluminum chloride and aluminum chlorohydrate, processes and compositions: high-basicity and ultra high-basicity products

A chamber for depositing a film layer on a substrate includes a support member on which the substrate is positioned for processing in the chamber, and a ring assembly suspended in the chamber on a chamber shield. The ring assembly comprises first and second rings, the second ring being disposed intermediate the first ring and the substrate. The support member is positionable in the chamber to receive a substrate thereon, and further positionable to pass the substrate through the shield and thereby lift the ring assembly off the shield. After deposition is complete, the support member retracts through the shield, to reposition the outer ring on the shield. The inner ring continues to move downwardly with the substrate support member a short distance before it is repositioned on the shield. In the event that a deposition material layer has formed between the substrate and the outer ring, the inner ring includes a plurality of tabs thereon which contact the substrate to force it out of the ring assembly as the inner ring continues downwardly after the outer ring has been positioned on the shield.
