Paper-Eating Dog

A minister delivered a sermon in 10 minutes one Sunday morning, which was about half the usual length of his sermons. He explained, "I regret to inform you that my dog, who is very fond of eating paper, ate that portion of my sermon which I was unable to deliver this morning."After the service, a visitor from another church shook hands with the preacher and said, "Reverend, if that dog of yours has any pups, I want to give one to my minister."

George Harold Brown

Died 11 Dec 1987 at age 79 (born 14 Oct 1908).American electrical engineer, a pioneer in radio-thermics, who made major contributions to the development of radio and television broadcast antennas. In 1936, Brown invented the so-called turnstyle antenna for television broadcasting. Because of this, the Federal Communications Commission (FCC) adopted a TV system of 441 lines. In 1938, Brown developed the vestigial sideband filter for use in television transmission, doubling the horizontal resolution of television pictures at any given bandwith. During WW II, with RCA's researchers, George Brown's group used radio-frequency heating in the bulk dehydration of penicillin at E.R. Squibb, a "sewing machine" for thermoplastics, and more consistent riveting and welding techniques.Image: Modern weather satellite receiving turnstyle antenna.
