摘要:
A waterborne coating composition for application to a donor member surface includes a resin binder, a conductive particle material, an additional particle material of either (1) graphite particles with a dispersant of polyacrylamide, polyethylene oxide, polyvinyl alcohol or mixtures thereof or (2) crosslinked polymer particles, and water. The waterborne coating composition exhibits superior stability and achieves suitable properties when coated upon a donor member surface, thereby permitting practical replacement of volatile organic components typically used in donor member coating compositions.
摘要:
The present invention relates to improved methods of coating donor members with waterbome coatings, wherein a resin, a pigment, and water are combined in proportions effective to provide a donor member precursor composition; the donor member precursor composition is subjected to high pressure communition to provide a donor member conductive coating composition; and the donor member coating composition is coated onto a substrate. The present method advantageously provides a donor member coating which is substantially free of air pockets or defects. In preferred embodiments the resin is a phenolic resin, preferably a waterborne phenolic resin, such as a phenol-formaldehyde resole, and in other preferred embodiments the pigment is selected from the group consisting of carbon black, graphite, magnetite, nigrosine, and combinations thereof.

Magnetic medium recording performance can be enhanced by irradiating a magnetic medium with ions having an acceleration voltage of between 10 keV and 100 keV to induce exchange coupling between grains of the magnetic medium. The magnetic medium is exposed to a cumulative ion dosage of between 1013 ions/cm2 and 1017 ions/cm2 using a non-patterned exposure of the magnetic medium. The ions can be selected from the group consisting of H+, He+, Ne+, Ar+, Kr+, and Xe+. Alternatively, the ions can be selected from the group consisting of Ga+, Hg+, and In+.

摘要:
A two mass, single motor bi-directional conveyor for conveying solid objects, granular and powder material. The unit utilizes the two mass sub-resonant natural frequency system driven by a single motor with counterweight wheels. The forces created by the rotation of the counterweight wheels results in a trough stroke at an angle from the horizontal pan resulting in material motion. The trough stroke is absorbed with isolation springs mounted between the conveyor and the ground.

摘要:
A balanced flat stroke bi-directional conveyor for conveying object, granular and powder material. The unit utilizes the skewed sine wave trough stroke principle using primary eccentric counterweights wheels driven by a motor running at the secondary speed and equipped with the secondary eccentric counterweight wheels and a third counterweight wheel. The forces not in line with the trough stroke are absorbed with an isolation spring mounted between the drive assembly and the base, while the forces in line with the trough are balanced via a connected balancer.

Flexible tubing derived from laminated polymeric materials having inner and outer walls wherein the inner wall of the laminated tubing is substantially resistant to bacteria growth and consist essentially of thermoplastic silicone rubber, and the outer wall of said laminated tubing consist essentially of polymeric rubber derived from a polymeric blend comprising olefin polymers. The flexible polymeric tubing is particularly useful in aqueous systems such as tubing for milk and portable water.
