Calibrator E. Machlett & Son offers t h e W a r b u r g manometer calibrator for the calibration of W a r b u r g constant volume m a n o m e t e r s . T h e instrument is said to simplify unci shorten the calibration procedure, b \ eliminating the handling and weighing of merciii) . It is designed t o make t h e calibration ot a W a r b u r g manometer simple, rapid, and precise. Each division of the micrometer scale of t h e calibrator represents a volume displacement of 0.001 nil. T h e calibrator can be used effectively w h e r e \ e r extreme accuracy is required to determine fluid or gas volume displacement ( pipcts a n d microhurets '. according to the manufacturer. E 1 P l a t f o r m Beam Scale Called the Load King, the scale developed by the Yale 6c Towne Mfg. Co. is designed for heavy-duty industrial applications w h e r e "shock-loading" is t h e rule. T h e lever system in the platform is allsteel as are other key parts. No wood is used. Poises on the main bar are m o u n t e d on roller bearings for rapid positioning.

Other features of the new scale include a n end loading platform that, according to the company, gives the same reading regardless < >l the location of the load on t h e piatlor in. T h e platform, which is mounted o n outboard bearings, also absorbs the s i lock of moving loads without d a m a g e to the scale. It will not tip. Pit requirements lor the Load King are only 1 1 in. E 2 Fired Heoters for Process H e a t i n g Struthers Wells has designed a sr-uulard line ot direct bred heaters designed tor high tlierniiil efficiencies and for applications wliiel i include indirect circulating heatin.u usieigheat transfer mediums such as Dowtlienn, a n d for direct heating of vapors and liquids. Capacities are 100,000 B.t.n. per hour to 15,000,000 B.t.u. per hour, while temperatures range to 750° F. or above. Operating costs may be comparable with those for steam boilers in smaller
