TheHoneywell Visicorderoscillograph

records forces incircuit breakerbushingsWham! Forces imposed by the operation of oil-

filled circuit breakers especially during short-cir-cuit interruption-are destructive enough to damagebushings. Engineers at the Ohio Brass Company havedevised an ingenious method of simulating this ex-plosive force in order to analyze bushing loads.On a typical bushing, they mounted a dummy in-

terrupter, in which they exploded gunpowder to pro-pel from the interrupter fist-sized metal projectiles.

Strain gages, installed on the bushing groundsleeve, were connected to a Honeywell 119 Amplifier.A Honeywell 906 Visicorder oscillograph was

chosen to record the test data because ofthe extremelyhigh speed and transient nature of the signals to bemeasured.A typical record of this test, shown at right, was

made at a record speed of 50"/second.These Ohio Brass tests have opened the way to the

development of standards for the mechanical per-formance of bushings (AIEE papers 62-153, 60-107).

This application is only one of thousands wherethe Visicorder is called upon daily as a basic research,test, and development tool. One of the six differentVisicorder models should be a basic instrument inthe management of your data acquisition.

Schematic at left diagrams method for duplicating bushing loads during short-circuitinterruptions. Projectile (A) produces lateral forces at right angles to bushing axis;projectile (B) produces axial load on bushing terminal. At right, squibs havejust detonated charges propelling projectiles from dummy interrupter. Below,Honeywell Model 906 Visicorder Oscillograph records circuit breaker bushing testfor Ohio Brass.

What's Castle's big idea that kills spores in heat and moisture sensitive objects?The Castle "idea" is Sterox-O-Matic with prehumidification. It means we inject water vaporbefore the ethylene oxide gas. This produces the essential environment for gas penetration.Castle research found this technique assures sterilization. It makes a significant reduction in

sterilizing time, too. For speed, safety and positive gassterilization, Castle Sterox-O-Matic is the leader. It isan automatic, error-free sterilizer that can safely save

you time and money. Write for complete informations L~~~~~~~~.on industrial applications, Wilmot Castle Company,17331 East Henrietta Road, Rochester 2, New York.
