Title: Richard D Goldberg: Innovator in Concrete Finishing Technology
Introduction
Richard D Goldberg is a notable inventor based in Hartford, WI (US). He has made significant contributions to the field of concrete finishing technology, holding a total of 5 patents. His innovative designs have improved the efficiency and effectiveness of concrete finishing equipment.
Latest Patents
One of Goldberg's latest patents is for a riding concrete trowel with stabilizers. This invention features a stabilizer that is operatively disposed between the frame and either the gearbox or a structure coupled to the gearbox. The stabilizer reduces the effects of rotor assembly vibration on the trowel, enhancing its performance. In one embodiment, the stabilizer is a gas spring located between the frame and the pitch control post, strategically positioned to take advantage of the mechanical advantage offered by the spacing between that location and the gearbox.
Another significant patent is for a portable vibratory screed with a bubble vial inclination indication system. This portable screed includes a blade connected to a handle that can be manipulated by an operator. Nodes of minimum vibrational amplitude are formed at specific locations along the blade when the exciter is driven at a rated operating speed. A site level and/or the handle is attached to the blade at or near these nodes, ensuring it is relatively isolated from induced vibrations.
