  • Patent number: 6129326
    Abstract: Bolted mounting assemblies for use between two mounted components wherein one of the components experiences vibration typically use rubber shock absorbers to dampen the vibration transfer between the components. The rubber shock absorbers are expensive and complicated to manufacture and are limited in flexibility control. The present invention overcomes this and other problems by providing an adhesive with damping capabilities between washers in a bolt assembly. The bolt assembly is used to mount first and second components with the washers therebetween. The adhesive is spaced a predetermined distance from a longitudinal axis of a bolt and has a non-uniform thickness which increases as the distance from the longitudinal axis increases to provide protection from bending loads about the axis. The washers with adhesive form a washer assembly with damping and flexibility characteristics controlled through variations in the design.

  • Patent number: 6079703
    Abstract: This is a system/method of clamping or securing or connecting one or more objects together in a wide variety of ways with the main means being a specifically designed bar and mated slot combination. While the main embodiment is the "Handy Table" project, there are many other ramifications of this invention. The bar and slot design can be altered to perform many other tasks where some way of attaching one or more objects to another need be accomplished. The main embodiment is, in my estimation, the most advanced type of work or project surface. The combination of a tri-sectional work surface, adjustable in a variety of ways, in size, in tilting, in multi-angle clamping capability, in precision height adjustment, and in the ability to transport the object being worked on easily, plus the addition of accessaries that enhance the overall capabilities of the "Handy Table", make it useable by many different professions and by the average project worker, be it man or woman, young or old.
