17th Midwest Regional Meeting
It's better t o g e t it f r o m Eastman . . .
The 17th Midwest Regional Meeting will be held Nov. 8 and 9 at Iowa State College, Ames, in the Memorial Union. It will b e sponsored by the Ames Section of the ACS. Technical programs will be conducted in analytical chemistry, chemical engineering, organic chemistry and biochemistry, and physical and inorganic chemistry. The chemical engineering program features symposia on phosphate fertilizer manufacture and on agricultural products. The physical and inorganic chemistry program will have a symposium o n rare earth chemistry. A mixer has been planned for the evening of Nov. 8 and will be held at the Ames Golf and Country Club. Registration fee is $3.00. Registration facilities will be available in the lobby of the Memorial Union from 5 to 10 P . M . Nov. 7 and 8, from 8 A.M. to 5 P.M. Nov. 8 and 9. Correspondence on housing should b e addressed to John Corbett, Chemistry Department, Iowa State College, Ames, Iowa, indicating type of accommodations desired. Correspondence about the program should go to Robert S. Hansen at the same address.

RUBBER TUBING EXPANDER, ELLIOTT SAFETY TYPE (Patent applied for). For safe, convenient connection of rubber tubing t o glass tubing without need f o r a lubricant. Rubber tubing can be stretched readily at the open e n d f o r easy access o f a cylindri cal object. The stretch is effected by three parallel tines whose tips are simultaneously diverged b y a system of levers upon com pressing the handles. The device is o f chrom ium plated metal with plastic grips and has been approved b y Safety Committee o f one of the country's largest industrial laboratories. To operate, tines a r e inserted into end o f rubber tubing which can be spread open by squeezing the handles. The glass tubing is guided between a n d slightly beyond ends of -the tines which are then unlocked by M o r e detailed
information
pulling a trigger. Tines are retracted without dislodging the glass tubing simply b y re peating pressure on handles. For use with rubber tubing from approxi mately 14-inch t o %-inch bore. Not intended for use with pressure o r vacuum tubing with thick, rigid wall, or with plastic tubings such as Tygon or polyethylene, which are less elastic than rubber. Overall length of 1 2 inches permits con nection o f tubing in assemblies at junctions which ordinarily might not b e accessible. 8853.

Tougher top coatings t h a t give increased resistance t o block» ing, crocking, a n d plasticizer migration· Supported fabrics and plastic sheeting are also» given, increased resistance to soil ing, abrasion, tearing, repeated flexing, moisture and chemical attack through top coatings of high molecular weight straight PVC resins effectively dissolved by THF.
M o r e durable, chemically inert protective coatings· The ability of T H F t o produce high solids contents solutions of high molecular weight PVC resins permits the manufacture of n e w protective coating formulations which were n o t possible with other solvents. T h e increased toughness and chem ical inertness of t h e high molecular w e i g h t straight PVC resins means protective coatings which give longer lasting protection. THCF's liigh volatility and high rate of diffusion through PVC resins reduce the time required between coats and/or to obtain a solvent-free film.
Stronger P V C films a t higher production speeds· N o t only are films of high molecular weight straight PVC cast from T H F stronger, but the solvent's h i g h volatility and high rate of diiffusion permit higher machine speeds. Be certain you investigate the possibilities of better coatings using high molecu lar weight straight PVC resins, T H F makes their application practical. T H F is available in quantities from working samples to tank car lots.
