Sec. 110(a) (10). Inflammable liquids flashing below 20°F. when packed in a single inside glass, earthenware, or metal container of not over 1-gallon ca pacity m a y now be shipped in an outside plywood drum Spec. 22A or 22B. The outer shipping container was formerly limited to Spec. 21A fiber drum. 4. Sec. 21 IB (a). Thorium metal, powdered has been added t o the list of inflammable solids and oxidizing materials and must be packed in Spec. 15A or 15B wooden boxes in inside packages fabri cated from metal. Metal cans must have tightly closed push-in covers secured by soldering at a minimum of 4 points or screw in cap type closures. Inside con Goodyear
tainers are restricted to 10 lb. net. Gross weight of shipping container must n o t exceed 75 lb. each. 5. Sec. 261A(a) (b), (c). Ethyl Chloroformate and Methyl Chloroformaie. These materials have been classed as corrosive liquids. They may be packed in Spec. 15A, 15B, or 15C wooden boxes with glass inside containers not over 1 pint each, cushioned with incombustible mineral material.

Ertel Vacuum, Bottle
Filler
The Ertel Engineering Corp., Kingston, Ν. Υ., announces a new vacuum bottle filler known as the Pneumo-Vac. According t o the manufacturer it is suitable for rapid filling of bottles and jugs within the height range of 3 to 13 inches, and the semiautomatic unit has an aver age filling speed measured in quarts of 50 bottles per minute. Activation by a balanced foot valve permits free use of operator's hands.
packaging
N e w l y designed valve-type spouts pre vent drippage while in operation. Liquid filling height can be accurately and simply regulated and will not vary until reset. T h e filler is available with liquid contact parts i n either bronze plated or stainless steel. Vacuum pumps are automatically lubricated and are enclosed in a n easily
accessible cabinet along with vacuum selector valves and motors. The circula tory system lends itself t o speedy flushing with suitable solvents, and enamel and plated exterior surfaces are easily cleaned. Pilot lights indicate operative position of vacuum circuits and liquid is supplied to reservoir of filler by gravity where a constant level is maintained by float valve control. The Pneumo-Vac l e n i s itself t o use with conveyor lines where empty bottles are fed to the unit and filled ones leave for capping, labeling, etc.
