Radio-Controlled Rockets for the NEXT WAR (Apr, 1931)

Radio-Controlled Rockets for the NEXT WAR

ADVANCES in the perfection of radio control for airplanes, tanks, and battleships have made it practically certain that the next war will see the use of these fearsome weapons of destruction in actual combat. Latest of the radio-controlled death-dealing devices is the explosive rocket depicted on this month’s cover of Modern Mechanics and Inventions, now being secretly developed.

TV IN A CAR (Jul, 1958)


The kids looking so raptly at the TV screen at left are seated in the back of a moving automobile. This was a demonstration of an experimental auto television set developed by General Motors’ Delco Radio Division for Oldsmobile. It is dual-purpose, operating in a car and removable for use on line current. Having eight-inch screens, such sets were first shown by Oldsmobile this year at the Chicago and Detroit automobile shows.

Dog Leash on Spring Reel Plays Fido Like a Fish (Jan, 1941)

Dog Leash on Spring Reel Plays Fido Like a Fish

A leash attached to a spring-operated reel is a new wrinkle for dog owners. Encased in a light but sturdy aluminum housing, the reel carries twelve feet of waterproofed leash strong enough to hold a great Dane yet light enough for use with a Pekinese.

The Artificial Satellite as a Research Instrument (Nov, 1956)

The launches he explains in this article were a rousing success. Explorer 1, the first successful U.S. satellite launch discovered the Van Allen Belt. So I guess that worked out pretty well for him.

I love the idea of crowdsourcing the task of actually finding the satellite once its in orbit to an army of amateur astronomers.

The Artificial Satellite as a Research Instrument

Its pay load of 10 pounds will telemeter information about conditions at the edge of space. When its batteries have run down, we can still learn much by observing its flight

by James A. Van Allen

Most persons interested in space travel will be willing to wait until the second or third spaceship has made it to the moon and back before booking their reservations. The artificial earth satellites are another story. If all goes well, the first of them will be on orbit by early 1958, during the International Geophysical Year.

Self-stick Note Paper (Nov, 1980)

Origin of Post-Its?

Self-stick Note Paper

Adhesive-back notepaper sticks to almost any surface without staples, clips or tape. Bright yellow color attracts attention. When note has served its purpose, remove it with a gentle pull. In three sizes from 79c. 3M, 600 Third Ave., New York, N Y. 10016.

spray-gun artist (Jan, 1951)

spray-gun artist
WE wonder if the old masters, da Vinci, Rembrandt and Rubens writhe in their graves when Ralph DeGayner takes up his spray gun in pursuit of the Muse! For he seems to have reduced art to a mechanized process far removed from subtle nuances with a brush.

Paper Phonograph and Debut of LPs (Jan, 1932)

Phonograph Plays Paper Strips

ONE strip of paper will carry an evening’s entertainment under the new system developed by an Austrian company, under the title of the “Selenophon Piccolo,” by which the “sound tracks,” such as the standard moving-picture sound film carries, are printed in black and white on an inexpensive strip of paper. A thousand feet of this runs twenty minutes; the output of the photo-cell which scans it being amplified in the same manner as the output of the magnetic pickup used with an audio amplifier in phono-radio combinations. A single strip may carry as many as eight sound tracks, on each side.

Invention of Microwave Popcorn? (Mar, 1931)

The panel on the bottom left seems like a demonstration of making microwave popcorn. I have no idea what the ice was for. Perhaps to show that the popcorn wasn’t being heated?

Also, upper right panel, WTF? How does light make the apple move? Why does this involve a Rastus robot?

New Developments in Electricity

This powerful “Stroboglow light,” synchronized with the revolving fan blades, makes them appear as if standing still. Airplane props are studied similarly.

Above — Corn in the container between the two jars of ice was popped in two minutes by heat from high frequency radio waves directed at the kernels.

New Electron Tube “Sees” the Invisible (Apr, 1936)

New Electron Tube “Sees” the Invisible

AN artificial eye, which extends the range of human vision into the dark areas of “ultra-violet” and “infra-red,” is now available for scientific use, and will undoubtedly be turned to many purposes of everyday life in the next few years.

It has been possible, for years, to take photographs by the aid of radiation which is invisible to the eye, and to develop them in a few minutes.

Takes the Drudgery Out of Mopping (Feb, 1940)

Takes the Drudgery Out of Mopping

MADE of cellulose sponge, the “business end” of this new floor mop absorbs twenty times its own weight in water yet remains soft and workable. A rectangular metal part with handle provides a squeezing device that wrings out the soiled water, which need not touch the operator’s hands. Only a slight pressure is necessary to squeeze out the water. There are no gadgets nor parts to get out of order. The mop can be used easily and quickly for cleaning walls as well as floors, and rugs also. The mop head can be detached for use in window and auto washing.
