There were approximately 100 participants from 28 companies represented. The participants were divided into three groupe to provide a more intimate environment during the presentations. The symposium was orgsnized very professionally by Brian Jaggera, President of the BSP.
Five participating companies presented products, the delivery of which was clear and concise even for the non-technical listeners.
The speaker for Firmenlch, Switzerland, was Dr. D. Kastner.
