Two Turntables and a Microphone (Jun, 1936)

Wow, where do you think the DJ’s got the idea?

Mechanical Reporter Substitutes for Human Stenographer
A MECHANICAL reporter, used for the first time at a Federal Communications hearing in Washington, threatens to replace the human stenographer.
Two large phonograph-type records are employed. When the first record is consumed, the machine automatically shifts to the other record.
The recorder operates with 100 per cent accuracy. It can take dictation at any speed and occupies only the space of any ordinary desk. It is said to be especially adaptable to courtroom use. Special devices render the machine practically noiseless.

TAXI PLANE Picks Up FREIGHT And Passengers for AIRLINER (Mar, 1935)

TAXI PLANE Picks Up FREIGHT And Passengers for AIRLINER
HIGH speed taxi planes that can come and go from a giant “mother” air transport at
will are proposed as a means of providing fast, non-stop transcontinental air service. The smaller ship, released over a city, would land at the airport to discharge and take on passengers and freight, then soar upwards again to catch up with the slower airliner.
As may be seen from the sketches, the method of launching the taxi plane is very similar to that used by the U. S. Navy in handling pursuit planes on dirigibles. A trapeze crane lifts the small ship into the hull of the transport, where passengers may be transferred to roomy quarters on the airliner.

Autogiro Blades Form Screen for Floating Ads After Dark (Sep, 1935)

This reminds me of all those persistence of vision gadgets like clocks and hubcaps.

Autogiro Blades Form Screen for Floating Ads After Dark

DISPLAY advertising at night by means of a magic lantern suspended beneath an autogiro, with the rotating blades serving as a screen, is a German inventor’s latest medium for placing a product before the public eye.

The magic lantern assembly is placed in a torpedo shaped carriage equipped with vertical and horizontal rudders to keep it in perfect alignment with the autogiro flying above. It can be raised or lowered by means of a cable, for focusing the advertiser’s message on the blades. When landing, the projector is drawn up into the fuselage.

To insure perfect reproduction of the advertisement, the under sides of the rotor blades are specially treated. The autogiro has been found to be particularly adapted for this type of aerial advertising because of its ability to hover almost motionless in the air, while the blades revolve fast enough to form an uninterrupted screen.

Clock Phonograph (Oct, 1931)

Hmm, for some reason I don’t think these ever really cought on.

Clock Wakes Sleeper with Music

THE violent hatred which humanity has for alarm clocks, especially around the hours of daybreak, may be mitigated somewhat by the invention of a combination phonograph and clock which awakens a sleeper with the strains of music from his favorite orchestra or singer.

Both phonograph and clock motor is contained in a box the size of a large camera, and the hour for the morning serenade is set by knob as in an alarm clock. When out of use the case is folded up to make a neat and attractive table or mantel ornament.

Nix on Parties – with my crop of Pimples (Mar, 1936)

Nix on Parties – with my crop of Pimples
Don’t let Adolescent Pimples kill YOUR dates!
AFTER the beginning of adolescence—from about 13 to 25, or even longer—important glands develop and final growth takes place. This causes disturbances throughout the body. The skin becomes oversensitive. Waste poisons in the blood irritate this sensitive skin, causing pimples.
Fleischmann’s Yeast clears the skin irritants out of your blood. Then pimples disappear! Eat 3 cakes a day, before eals—plain, or in a little water—until your skin clears.

OIL – Modern WAR GOD Threatens the World (Feb, 1936)

Gee, things sure have changed a whole lot since then.

OIL – Modern WAR GOD Threatens the World

Black gold, precious underground liquid, is food for the modern war machine. Deprived of it, a nation’s military campaign is threatened with failure. Will oil become an instrument to enforce peace or to cause war?

WITHIN the last few decades, oil has changed from an almost unknown and unnecessary commodity to one of the world’s most vitally needed materials. Oil, unlike nitroglycerin, has always been an innocent, viscous fluid used for lubrication and fuel. But harmless petroleum, like Dr. Jekyll, has undergone a startling transformation. Oil may yet be the means whereby the flaming torch of war is carried across the world.

“Lunch Wagon” For White House (Apr, 1936)

My god. I think the technology here is just too advanced for me to understand. It keeps food hot? And has wheels? Impossible! That president is one lucky fella!

“Lunch Wagon” For White House
A LUNCH wagon de luxe, encased in glittering metal and rolled upon balloon tired wheels, has been placed at the disposal of President Roosevelt. When the Chief Executive finds himself too busy to take time off for lunch, the lunch wagon is pushed in, and he is served a piping hot meal.

Harness Prevents Running Escape (Apr, 1935)

Harness Prevents Running Escape
A HANDCUFF harness which prevents a prisoner from running away has been devised by Guy E. Lombard, Portland, Maine jailer. The harness consists of a steel ring held to the prisoners’ waist by a stout leather belt. The handcuffs are fastened to the belt, holding the prisoner’s hands so close to his body that he cannot gain balance to run.

HILL HOPPING A WORM DRIVE SLED (Mar, 1936)

HILL HOPPING A WORM DRIVE SLED

FROM California comes a radical innovation in motor driven vehicles, a worm drive ski-sled. Powered by a 35 horsepower engine, it negotiates the steepest, roughest inclines with ease, and on level snowfields has attained speeds of twenty and more miles per hour.
With a more powerful motor, considerably higher speeds are expected, and the initial success of the experimental model may lead
to an entirely new sport in the form of motor ski racing and jumping. In order to achieve the latter sport, it will be necessary to mount the runners on shock struts, both to protect the worm-drive blades and the rider. This would be a simple matter.
More practical vistas opened by this novel sled lie in its adaption to the needs of Arctic exploration parties in their long treks over snowbound wastes.
