Best room in the hotel?

The drunk staggered up to the hotel reception and demanded his room be changed.

"But sir," said the clerk, "you have the best room in the hotel."

"I insist on another room!!" said the drunk.

"Very good, sir. I`ll change you from 502 to 555. Would you mind telling me why you don't like 502?" asked the clerk.

Compotype

In 1925, the compotype was patented by its inventor, Clifton Chisholm of Cleveland, Ohio, as an "Embossing Machine" (U.S. No. 1,557,754). The keyboard-controlled machine embossed one line of characters on an aluminum strip with flanged edges. These could be arranged in a holder for several strips in parallel from which several lines of printed material could be produced. Blanks came from a ribbon of metal on a roll, automatically flanged to give a mounting channel shape, and fed between embossing dies. Each character was also printed on a record card, visible during operation. The machine was designed to provide an efficient mechanism for the rapid production of the embossed strips. The patent was assigned to the Multigraph Sales Co. of the same city.
