BETHLEHEM BENCH BURNER SURFACE-MIXED AIR-COOLED
GAS-OXYGEN
Two concentric fires—operate inde pendently or as one. Central fire can be varied from sharp needle point to long powerful jet, able to handle hard glass up to 35 mm. Using both fires, quartz up to 25 mm or hard glass up to 100 mm can be handled with low pressure citygas. Larger sized quartz requires hydrogen with oxygen.
Balances. Single pan. Compact base, compensated beam, large chamber. 144 Barium Chloranilate. Determines sul fate in less than 1 / 2 hr. Data. 67 Blenders. Info on new twin-shell blender with 3 mixing actions. 16
The unprecedented temperature ranges are due to a special adaptation of the surface-mixing principle—especially impressive to those accus tomed only to premix burners. These fires are completely silent, without chance of flashback.

COMPLETE AUTOMATIC DE-IONIZER Here is a complete, loaded, fullyinstrumented, automatic ionXchange unit in a neat, compact, and ready-tooperate "package." I t is equipped with our own Illco/Matic, all-plastic, aira c t u a t e d valves, which have been specially developed for ionXchange service. The Control Panel, also our own design and manufacture, provides all necessary quick-adjustment features, and requires only electrical hook-up to the terminal box on the frame. The only other connections required are to plant service.
FULLY ASSEMBLED A N D READY TO INSTALL All structural assembly of elements, all piping, all wiring, and all installation of air lines is done in our factory by men of long experience. Then the unit is tested for proper operation of all circuits, loaded with the proper supporting beds and resins, painted, bolted to a skid, and crated for delivery to the exact spot it will be used. This is the quickest, easiest, and surest way for you to get a reliable, ready-to-go ionXchanger — arranged and instrumented to suit your special needs, whatever they are.
