New Inventions (Jun, 1935)

New Inventions

A VERY assorted collection of recent examples of inventive ingenuity—some very practical— are presented here. For instance, the smiling lady at the upper left has a safety device which recalls the foundation of the old-fashioned hoopskirt. With this, you can learn to skate safely; if you break through thin ice, the rim will hold you up; and if you go through entirely, the life-preserver will take charge.

The genial gentleman in manacles is an officer who does not desire to run too fast after felons. A prisoner in these has his hands held too low to sprint.

Upper right, a “thought-measurer” which, like other psychological machines, rather tests muscles and circulation responses. A pad, dampened with salt water and clamped to the wrist, is connected to an amplifier, and the result shown on the scale.

Center, a convenience designed for the bedridden who are musically inclined. It is easily rolled around the room.

The skates, center right, are made to their user’s order, and a very attractive job. The paper-thin metal is strong and gives a perfect grip.

Left and right, bottom, two commercial products of apparent utility. The gas detector was made for use in mines; it samples about a cubic foot of air a minute, and announces the result.
