...Uncle David" seemed again last week the boyish Prince of Wales and not the 42-year-old King-Emperor when he went out to test the British Admiralty's new "Flea Boats." These are high-speed motorboats firing torpedoes. For months British capital ships infesting Italian waters have been bothered by such "Fleas...
...close inspection of the tunnel walls. All electrical connections were shielded against sparking in the presence of sewer gas whose explosive power, Mr. Brown told reporters, was such that 36 cu. ft. of it was equal to one ton of dynamite. Last week Mr. Brown made a preliminary test of his equipment. He put on woolen basketball socks, sneakers, short hockey pants. He ate a huge breakfast of hot cakes and bacon. Then he got into a rubberized suit, hung a gas mask on his chest, a radio transmitter on his back. His crew lowered him and boat through...
Last week the American Society for Testing Materials met in Atlantic City. The 4,400 members of this society are the insurance agents of U. S. industry. They decide exactly how thick and strong a piece of wire must be to make a good bridge cable. They decide how thick and strong a bolt must be to hold an automobile body securely on its chassis.

Fast Dye. Two specimens are cut from the piece of cloth. One specimen is used for the test; the other saved for comparison after the test. The test specimen is sewed to a piece of bleached cotton cloth and placed in a jar of hot (160 degrees F.) soapy water with ten ⅜-in. rubber balls.

After thorough rinsing in warm (110 degrees F.) water, drying and ironing (at 275 degrees...
Footwear. After trying out fantastic "walking machines" to determine the durability of rubbers, tennis shoes and boots, and finding their results unreliable, manufacturers now test rubber footwear part by part. One machine, which Manager W. E. Glancy of Hood Rubber Co. Laboratories described last week at Atlantic City, has all the wheels and most of the gadgets of a lathe for turning out baseball bats. It is used to pull eyelets out of tennis shoes, a dial registering the force needed. A machine with a rocking arrangement stretches sheets of shoe rubber until they tear. To test the safety...
