Lux Fire-Fighting Labora­ tory Dedicated T A LUNCHEON held at the Arrowhead A L Inn, New York, Ν. Υ., on November 15, the Lux iAboratoryof Fire Fighting was dedicated by the Walter Kidde Co. The laboratory is housed in a 10-ton truck, and after a demonstration showing the use of carbon dioxide as a fire-extinguish­ ing agent, the laboratory departed on an exhibition tour which will include all the principal cities of the United States. During the demonstration, held before 300 guests, gasoline, oil, alcohol, lacquer, and acetylene were set on fire and then ex­ tinguished with Lux carbon dioxide fire extinguishers. A car, reclaimed from a junk neap, was then liberally doused with a mixture of oil and gasoline, set afire, and a portable tank extinguisher, rushed from the mobile laboratory, was used t o stop the blaze. Other tests, standardized by the Underwriters laboratories, were part of the exhibition. The use of carbon dioxide as a firefighting agent has increased rapidly dur­ ing the past few years. The New York Municipal Airport's new fire truck carries thousands of pounds of compressed carbon dioxide and can entirely envelop an air­ plane with the gas. Transport and mili­

tary planes are equipped with lightweight cylinders o f t h e compressed gas. Trip­ ping a valve will release the carbon dioxide to the motor compartment and, despite the slipstream, the fire may be smothered successfully. The rubberized vest worn in unfiated form by naval fliers contains a tiny steel cylinder, similar to the cartridge used t o charge home siphon bottles. Pulling a cord attached t o the vest punctures the cylinder a n d t h e released gas inflates the vest, making i t a life preserver. In the same field the research engineers of the Walter Kidde Co. have developed "air­ plane water wings" for use o n naval craft. These so-called water wings, or flotation gear, consist of rubberized nags carried in compartments i n wings of fuselage, which are automatically inflated b y compressed carbon dioxide as soon as water strikes one of t w o detectors. These detectors, located at t o p and bottom of the fuselage, inflate the bags regardless of whether the ship pancakes, dives, or lands in the water upside down and work automatically, even if the pilot is unconscious or has aban­ doned the ship b y parachute. Similar carbon dioxide pressure cylin­ ders are attached t o rubber life rafts now carried on most over-water flights. Originally the use of carbon dioxide for smothering fires was developed a s a method of fighting fixes in ship-holds, and at one t i m e the Kidde engineers hired a ship, installed the necessary equipment, and invited a group of English shipowners to witness the demonstration which was held on the Thames River. The ship-hold was set on fire with gasoline and oil, and the success of the experiment is attested by the fact that many ships, including the Queen Mary, now use this system. The gas is also of particular value in electrical power plants, where it may be used without fear of decomposition or the grounding o f the circuit through the body of the fire fighter.

Registration. All persons attending the meeting must register. The registration f e e is $1.00 for members of the AMERI­ CAN

CHEMICAL

SOCIETY, students,

and

nonchemist guests, and $2.00 for chemists w b o are not members of the SOCIETY. Reg­ istration will be in the Chemistry Buildins. Social Features. There will be group luncheons on Thursday and Friday, and a dinner Thursday evening at the Uni­ versity of Michigan Union. Tickets for t h e luncheons and dinner may be purchased at the time of registration. The toastmaster for the dinner will be Walter L. Badger. The principal speaker will be Jolin F. Worley. Hotel Accommodations. The Univer­ s i t y of Michigan is prepared to accommo­ d a t e those who are registered at the sym­ posium, either in the Union itself or in the men's oormitories. The rates per person vary from about $1.50 at the dormitories to about $3.00 a day at the Union. .Abstracts of Papers.
