...Yeager of the Department of Agriculture projected on a screen a cardiogram from the beating heart of a cockroach. This was obtained by exposing the heart of the insect and placing on it a minute drop of wax. A human hair inserted in the wax was connected through a lever to a fine wire. The heart beats thus jerked the wire and a light beam passing across it translated them into a pulsating graph. The Department uses this method to study the cardiac effect of insecticides...
Inventor Burt's machine, made entirely of wood, was destroyed in the Patent Office fire of 1836. It was a ponderous gadget with the type carried on a circular frame operated by a lever. That Burt could write faster with his machine than by hand is highly improbable. Yet it had a feature that was lacking in some commercial machines for many years: separate sets of capital and lower-case letters, with a shift mechanism for changing from one to the other...
...agreed to sign a declaration that they were guilty. The third, although his jaw was broken, still refused to sign. While police again held him down, a Japanese detective jabbed the point of a fountain pen deeply under the sailor's nails and vigorously worked the fountain pen lever, shooting ink into the wounds until the sweating prisoner agreed to take the pen, sign a confession...
...when familiarizing oneself with the instrument layout and control locations of a new model. . . . I saw the red telltale bulb glow on the ignition switchboard. . . .

In the Cornea store an attendant fastens the bird's head into a clamp from the short, inside belt. About a foot farther on, a lever is pressed down, completing an electrical circuit. Some 1,000 to 1,500 volts, depending on the size of the fowl, stepped up by transformers from ordinary house current, pass through the victim, shooting out its tail like an angry cock's, stunning it instantly. The fowl passes...
