INDULIN As a ceramic binder, INDULIN (pine wood lignin) imparts remarkable strength to dried but unfired bodies, preventing breakage. In printing inks, INDULIN is a pigment binder — non-tacky, non-thermo-plastic, and cnemicaUy inactive under printing conditions. INDULIN also acts as a binder for dry process sawdust board manufacture. As a product of wood pulping, INDULIN is available in unlimited quantities at a low price. Our technical staff will be pleased'to discuss use possibilities in your process. Send for Bulletins 103 and L-6.

born in Chicago in 1916, attended public schools there, and entered the University of Chicago in 1933. H e leaned toward a career in physiology and while getting the thorough background in chemistry needed for this field, he turned from physiology to chemistry. He received a Rhodes scholarship after getting his B.S. and spent two years at Oxford, where he studied with L. E. Sutton the dipole moment in solution of symmetrical molecules with anomalously large atom polarization. After receiving the B.Sc. degree in 1938, he began predoctoral work on properties of trimethylaluminum and its addition compounds, but outbreak of war interrupted his studies. However, war had not begun soon enough to prevent several bicycle trips on the continent through the wine country of France and into Germany. After completing work at Chicago in 1941, he worked with Anton B. Burg at University of Southern California and L. O. Brockway at Michigan before joining staff of uranium separation project at Columbia in 1942. After a semester as instructor at Illinois Tech, Davison joined the staff of University of Chicago's plutonium project. There, in Glenn Seaborg's section, he worked on extraction processes for plutonium and was group leader in the "dry" chemistry of plutonium. From ' 1945 to 1946, he worked at RCA laboratories on electron microscope research and studies of electron diffraction by solids. He joined Cal tech in 1946 and became associate professor six years later. At Caltech, Davidson shares with Linus Pauling responsibility for freshman chemistry—required of all students. He lectures, supervises laboratory sections and graduate student instructors, and, whenever possible, teaches a discussion group himself. He keenly feels that teaching a small class with its resulting close contact of students and teacher is most rewarding part of the college professor's job. H e also teaches a graduate course in chemical kinetics and supervises various research projects. While at Columbia, he met Annemarie Behrendt who became Mrs. Davidson in 1942. Little Davidsons now include Terence, Laureen, Jeffrey, and Brian, and Prof. Davidson's time for swimming, tennis, and camping is limited. But he fits in a set of tennis with colleagues or students when time permits and a camping trip w h e n Brian's baby-sitter permits. H e is currently a member of Caltech's committee on faculty-student relations and educational policies, and is chairman of the committee for teachei r ' institute. VOLUME

Just a nick of a switch, then read the dial, and with a Brookfield Viscometer on the job you have your viscosity determination directly in centipoises. The whole operation, including cleaning up, takes only a minute or two. High accuracy plus high sensitivity are inherent in the Brookfield principle of operatiojft— direct indication through a calrbratBJspring of the torque on a rotating spiplgi Changes in viscosity as small as l / 5 l | l j p % of scale can be observed. Ideal for use both in Labs and at points-of-process, Brookfield Viscometers plug in any ac outlet and are ruggedly constructed — have withstood the severest of service conditions the world over. ADAPTABLE TO ANY PROBLEM FRQffi 1 TO 32#00O,O0O CPS. ÉÊÊÊÊ^
Al||fi|ble in a variety of models — single spWed, four speed, eight speed, explosion-proof, etc.— Brookfield Viscometers are suitable for work with both Newtonian and non-Newtonian materials. They have become the standard instrument for nearly every type of viscosity determination problem, including such difficult ones as cream style corn and 2500°F.JSolten slag. A&pgtsory equipment such as the BrookijIjpUL Adapter makes possible measurements within .02 centipoises in the ultra-low viscosity range of .8 to 10 centipoises. The Brookfield Helipath Stand (another accessory) makes possible precise testing ofjhighly plastic materials such as grease, Jpptty, shaving cream, gelatin, shorten||(& etc.

Revolutionary in design . . . simple in construction . . . ef ficient in operation . . . the new Cenco Supervac Oil Dif fusion Pump offers important advantages. It consists of only three parts . . . jet manifold, jacket, a°nd boiler with de tachable heater. By simply loosening six cap screws, these three units come apart for in spection, draining, cleaning and filling. Cleaning of jets and internal surfaces is easily done with out disturbing connections to the vacuum or cooling systems. The pump is attached to the vacuum system by means of the new Cenco "O" ring con nectors and may be disconnected or re connected in a few moments, always with the certainty of a vacuum-tight seal. No other oil diffusion pump offers
this time-saving convenience. Used with a Cenco No. 92045 Hypervac-4 or No. 90550 Pressovac as the forepump, the unit obtains extremely high speed evacuation at low pressures. All parts are made of cold rolled steel except brass couplings and copper cool ing coil. Copper plated inside . . . copper and nickel plated outside.
