Velcro
Swiss electrical engineer George de Mestral invented his first touch fastener when, in 1941, he went for a walk in the woods and wondered why Burdock seeds clung to his coat and dog. He discovered it could be turned into something useful. He patented it in 1955 and subsequently refined and developed its practical manufacture until its commercial introduction in the late 1950s.

The show was the first to use the "Syncro-Vox" optical printing system because of budgetary limitations and the pressure to create animation within a tight time frame. Syncro-Vox was invented by Edwin Gillette, television cameraman and partner in Cambria Studios, as a means of superimposing real human mouths on the faces of animals for the popular "talking animal" commercials of the 1950s. "Clutch Cargo" employed the Syncro-Vox technique by superimposing live-action human lips over limited-motion animation or even motionless animation cels.
