HIGH FREQUENCY INDUCTION
HEATING UNITS
Lepel induction heating equipment represents the most advanced thought in the" field of electronics...the most prac tical and efficient source of heat developed for numerous industrial applications. You are invited to send samples of work with specifications. Our engineers will process and re turn the completed job with full data and recommendations without cost or obligations. FLOATING ZONE UNIT FOR METAL REFINING AND CRYSTAL GROWING A new floating zone fixture for the production of ultra-high purity metals a n d semi-conductor materials. Purifica. lion or crystal growing is achieved by ^reversing a narrow molten zone along the length of the process bar while it is being supported vertically 'in vaeumm or inert gas. Designed primarily for pro duction purposes, M o d e l HCP also pro vides great ftexihiliiy for l a b o r a t o r y studies.

A Smooth, positive mechanical drive system with continuously variable up, down and rota· ti'onal speeds, all in depend· enfly controlled. An arrangement to rapidiy center the process bar within a straight walled quartz tube supported between gas-tight, water-cooled end plates. Place ment of the quartz tube is ra ther simple and adapters can be used to accomodate Inrgei diameter tubes for larger pro* cess bars. Continuous water cooling for the outside of the quartz tube during operation. Assembly and dis-asscmbly of this system including removal of the completed process bar is simple and rapid.
