The housing of a rotary ball type industrial vibrator is injection molded from a reinforced plastic material and an annu-, lar metal raceway structure is molded integrally with the housing and forms a contact surface for a metal ball disposed within the interior of the housing. In response to a flow of pressurized air through the housing, the ball is rapidly rotated around the metal raceway to impart oscillating vibrational forces which are transmitted through the housing to a bulk material handling structure to which it is rigidly secured. The light weight plastic housing facilitates a highly efficient vibrational force transfer to the material handling structure and the integrally, molded …

Why it's free to use
- Filed August 30, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 30, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 30, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
