Latest Patents

**Non-staining solid lubricants.** This invention describes using a solid film of a saturated aliphatic monohydric alcohol containing 14 to 18 carbon atoms to lubricate metal during cold-working. After shaping, the film can be removed by heating without staining the metal surface. Small amounts of polybutene, petroleum jelly, or butyl stearate may be added to adjust the film’s properties.

**Shaping anodic aluminum oxide sheet.** Porous anodic aluminum oxide sheet can serve as a filter, but it is brittle after removal from its aluminum substrate. The invention describes shaping the sheet by flexing it across the direction in which the substrate was rolled, or by wetting it to make flexing in any direction easier. The shaped sheet can then be heat-set at temperatures from 200°C to 650°C.

Career Highlights

Pargeter’s listed patents focus on practical material-processing challenges. One addresses lubrication and clean removal during cold-working, while the other provides methods for forming and heat-setting brittle aluminum oxide sheet.

Collaborations

Pargeter is associated with Alcan International Limited. His listed coworkers include Dianne M. Jenkins and Mark H. Foster.

Conclusion

Christopher Pargeter’s patent work reflects an applied approach to materials engineering, with inventions for non-staining metalworking lubrication and the controlled shaping of anodic aluminum oxide sheet.
