WIZARD AND HIS TRICKS

WONDERFUL CONTRIVANCE:

BROWN AND WHITE BEANS.

At the top of -a block of offices in Regent 'Street, London, a wizard' has at his complete command a genie 'Of infin-ite-powers. ' He calls- his' slave: “The Electric Eye.” It opens doors/turns. lights Off and on, sorts black beads-from blue beads, and . tells whether a .bean is'/gqod to‘eat, or not. / . . . 7 - The wizard is Mr. Rex Horsfield, late consulting engineer to an' electrical com-pany-in America. He -is,'an. Englishman, with an American sense of humour: He has been in England to persuade business men and manufacturers to use the “Electric Eye” in the furtherance of:their lawful occasions, i When he was called upon recently, writes an Evening' News Correspondent, Mr.. Horsfield pointed to ' the electric eye. “Blow some smoke across ft,” he said. In the interests of science the visitor did so. A light changed from red to green and back again as the smqke faded. "Just sensitivity,” said the wizard. “I am frying to get them to put the ‘Eye’

in factories and restaurants. The i ea is that every time a workman or a wan-.-er approaches a door he crosses the.beam —and the door opens. You dont even have to know “Sesame.” ■ <■ Then Mr. Horsfield introduced his visitor to his favourite. If tells how ma y beans make five, spills the in fact, knows everything about, beans. “This is the idea,” he (said, . it .has already been tested , by one of the biggest canners in this country. “The photo-electric cell, which is, the basis of the electric eye idea >?® S f the light reflection thrown by object. A White bean affects; it in one way, a brown bean in another. White, beans are good beans. Very well. “Tons of beans are passed on_ an Aendless band through the ray. It M Mt to reject the brown beans. By means eff a jet of compressed air which is only operated by the fight reflection of a white bean, the white beans are shot off into a container. The others paM on into oblivion.”
