  • Publication number: 20260145739
    Abstract: A tie rod adjustment apparatus comprising a pair of supports for locating and engaging with a tie rod, and a pair of adjustment heads disposed between the supports, where a first one of the adjustment heads is configured for engaging and rotating a jam nut of the tie rod and a second of the adjustment heads is configured for engaging and rotating a rotatable tie rod end of the tie rod. The supports are configured to be stationary when engaged with the tie rod and the pair of adjustment heads are moveable along the tie rod between the stationary supports for selectively engaging the first adjustment head with the jam nut and engaging the second adjustment head with the rotatable tie rod end.

  • Patent number: 11752651
    Abstract: A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.
