Wilden Introduces Pumps Designed For Explosive, Hazardous Environments Effective immediately, Wilden Pump & Engineering Co., Colton, Calif., will offer electrically conduc- tive, graphite-filled Ml polypropy- lene models. These models have been introduced specifically for ex- plosive and hazardous environ- ments, where nonconductive plas- tics may be unacceptable due to static electricity discharge. These graphite-filled models need to be earthed (grounded) at one connection, whereas virgin poly- propylene requires grounding at all clamp bands or connection points. Surface resistance is less than 4 x 10 Ohm, thus providing adequate dis- persal of static electricity discharge when pumping nonconductive liq- uids. These pumps offer the same ad- vantages as all Wilden air-operated, double-diaphragm pumps: no mo- tors, no seals, no packing, run dry capability, variable speed, variable pressure, explosion resistant, and self priming.

LTC International Offers 'Dust-Free' Vacuum Blasting Units LTC International, Inc., Sterling, Va., offers high production vacuum blasting machines to maintain a vir- tual dust-free environment with production rates comparable to open blasting. Hose lengths of up to 165 feet and nozzle sizes of No. 4 through No. 8 are available. The machines have a unique double chamber pressure vessel system which, when using recyclable abra- sives, permit uninterrupted blasting operations. The equipment tested successfully for the removal and containment of lead-based paints at an independent University Civil En- gineering Laboratory.

This seminar is intended to assist naval machinery manufacturing compa- nies in getting involved with the R&D of new equipment for subma- rines. Speakers will be present from DARPA's Naval Technology Pro- gram, as well as from NAVSEA, and the Naval Research Center. A high- light of the program will be an R&D Forum to include representatives from industry and the naval re- search community.
