New Ideas

GOODS & SERVICES New Ideas Homing Tubes. An automatic system of pneumatic delivery tubes, developed by I.T. & T., went into operation in the Bridgeport Brass Co. The robot system routes carriers throughout the plant through a network of tubes, works on the same principle as a dial telephone. The operator sets a dial on the carrier, and electric contacts along the way send it to any one of nine plant stations.

Spartan Sparker. Boeing Airplane Co. has developed a new antifouling sparkplug for gas engines that it says is the "first significant design change in sparkplugs in 30 years." The new plug, not in production yet, has its ignition points recessed inside its shell instead of sticking out the end, has been run 20 times longer than other plugs without cleaning.

Plastic Cleaners. To get around metal shortages, Lewyt Corp. this week starts production on plastic vacuum cleaners, which will be quieter, stronger, and four Ibs. lighter than present metal models.

Quick Dryer. The Wood Electric Kiln Co. of North Berwick, Me. demonstrated a time-saving electronic kiln for drying green lumber. By using kiln-drying combined with high-frequency radiation, lumber in Wood's kiln can be dried in as little as 15 hours, instead of the seven to eight days needed in the present steam-heated type kilns.
