  • Anti-traction compositions
    Patent number: 7625848
    Abstract: An anti-traction material is disclosed which may be used as a coating on a variety of surfaces over which people and vehicles may find it difficult to traverse. The anti-traction material may include polymer particles capable of absorbing or being dissolved by a fluid and a fluid capable of absorbing or dissolving the polymer particles. The anti-traction material may include hydrophobic particles which may then control the rate and/or amount of fluid absorption of the polymer particles which may therefore improve storage capability and polymer particle flow behavior.

  • Accessory for boot
    Patent number: 5819997
    Abstract: An in-line roller skate that includes a boot having a sole plate to which an in-line roller wheel system is attached and further including a shell and a collar mounted for articulation on the boot for securing the boot to the leg and foot, a U-shaped clamping member having a front plate and an arcuate shaped back plate that conforms to the shape of the boot collar, the plates being cojoined by a base member wherein the plates are biased towards each other, the clamping member removably secured to the boot collar by passing over the boot collar at the spine with the back plate placed inside the collar wherein the back plate extends downwardly along the length of the collar to a depth that brings the base member into contact with the collar wherein the base member cooperates with the arcuate shaped back plate to prevent the frame from canting out of parallel with the spine, and the front plate having integral to and extending from it a frame for holding an article.
