THE P R O F E S S I O N A L SIDE
P I L O T P L A N T ROTARY DRYER T h e Ruggles-Coles Pilot Plant Dryer is designed especially for laboratory use or for small capacity unit operations requiring a continuous or intermittent
drying step. Each
unit:
• Is mounted on a structural steel base. • Has removable " k n o c k e r s . " • Provides for easy changing of shell rotation speed or shell slope. • Is available in stainless steel or other corrosion-resistant materials. • Requires only fuel supply and power connections to be placed in operation. • Is easily moved from place to place.
It is available in three models: (1) X H - X F single-shell, direct gas fired dryer. Arranged for either parallel or counter-flow operation. Bulletin AH-471. (2) X B double-shell, indirect-heat, gasfired dryer for drying without contamination. Volatiles removed with only limited dilution. Bulletin AH-472. (3) X C steam-tube indirect heat dryer. Can be connected to any available steam supply or furnished with a 3-HP steam generator. Bulletin AH-473. For complete ment 12.

INDUSTRIAL AND ENGINEERING CHEMISTRY
do the j o b well a n d with ease, he will probably be tapped for a promotion that will take him out of direct market research. However, the skills he has acquired in objectivity, open-mindedness, and good j u d g ment will be his forever. W i t h the chemical industry's innate habit of revolutionary change a n d progress, the a d a p t a b l e market researcher is in a n enviable position to advance more, rapidly t h a n m a n y . Not always, however, do market researchers use this field as a steppingstone to advancement. T h e r e is a nucleus of experienced and very able chemical market researchers who have become so adept in the field and so dedicated to this artscience that they have m a d e careers of it. T h e y are recognized within and outside their respective companies and are undoubtedly so needed where they are that they will continue their careers in this field. T h e y have set high standards of proficiency and through their continued example, speeches, papers, and other contributions are training today's neophyte. T h e y know better than most that chemical market research is a Topsy that is still growing; that chemical market research, by its very nature, must continue to grow with the industry of which it is an integral p a r t ; otherwise, too m a n y executive actions would bog down and many expensive errors would accrue to company stockholders. An individual considering chemical market research as a career can obtain a bird's-eye view of this field by reading a collection of papers by authorities on the subject available in the volume " C h e m i c a l M a r k e t Research in Practice" (Reinhold, New York). These papers were prepared and given as lectures in 1953 at the Case Institute of Technology, and at the University of Delaware in 1954; but the principles and techniques of chemical market research are unchanged basically since then. T h e lecturers, under the auspices of the Chemical M a r k e t Research Association, contributed their knowledge as a service to the industry and in the hope that more people would understand and enter the field. ; T h e scope of chemical market research is broad,· a n d it is both challenging and rewarding.
