...work. It will perform their function with more exactness, will cost less and, biggest advantage of all, it will not depend on daylight for its accuracy. The heart of the machine, invented by New York University's able young physicist Dr. Harold Horton Sheldon, is a photoelectric cell...
Light reflected from two samples of the same cloth placed in the machine, passes into the cell, gives an electrical impulse which is indicated by a galvanometre. The indicator hand is then set at zero, the unknown sample is introduced. If the hand again points to zero the match is perfect. If it varies to the right the second sample is too dark, to the left, too light. A variation of three calibrated scale divisions is considered a passable commercial match...
...Clifton and Einar sat in a Copenhagen dock. The two young frokener screamed charges that they had been treated worse than roughly. Einar, when he saw how things were shaping, "ran amuck in the courtroom" according to Copenhagen newspapers, and "overpowered by three policemen, was locked up in a cell, howling for drugs...
...list of 1930 lynchings. At the Chickasha jail, hundreds of mobsters besieged the guards of black Henry Argo, attacker of white Mrs. George W. Skinner and her child. During successive rushes the mob fired the jail, smoked out many of its defenders. A sniper climbed to Argo's cell, shot him in the head. Husband Skinner broke in and stabbed the prostrate body. Argo was smuggled as dead into a hearse, driven to an Oklahoma City hospital before he died...
...vacuum chamber and kept at constant temperature. The pendulum has no escapement, driving spring or other mechanical attachment. Instead it is provided with a small slit through which a beam of light passes at each swing of the pendulum. The beam of light falls on a photoelectric cell and produces an electric current of short duration each second. These current pulses drive an auxiliary second's counter and clock dial for registering the time and also give magnetically impulses to the master pendulum for maintaining its vibration. This clock is timed once a day by radio signals from Washington which...
