Two-Headed TV Set Displays Two Different Shows at Once (Mar, 1954)
Sharp reintroduced this idea last year with the Dual View, an LCD that allows two viewers to see different images depending on their viewing angle. Though frankly I think the glasses make this one look much cooler. Even the dog has a pair.
Two-Headed TV Set Displays Two Different Shows at Once
Two people can enjoy different TV programs at the same time with a new set. The experimental Du Mont Duoscopic is actually two receivers in one cabinet, with two chassis, two sets of controls and two viewing tubes mounted at right angles (inset). A semitransparent mirror superimposes the two pictures, but each viewer sees only one show by watching through polarizing spectacles. Earphones handle the sound.
Sunken Pillboxes Guarded Jap Coast (Mar, 1947)
I find this rather hard to believe. It doesn’t seem practical, nor does it seem that 40 people would be neccessary to man 3 torpedo tubes.
Sunken Pillboxes Guarded Jap Coast
Japan’s anti-invasion line went out under water at Tokyo Bay. Pillboxes were built into the hulls of sunken ships and equipped with three torpedo tubes and a sound detector. Each pillbox held 40 to 50
men who were relieved every 10 days. Food was canned; oxygen, bottled.
Filter Pipe Is Smoked Through a Cigarette (Nov, 1939)
This is brilliant marketing by the tobacco industry. Convince people that it is healthier to smoke their pipe tobacco through cigarette tobacco. There really should be some way to fit a cigar in here too.
Filter Pipe Is Smoked Through a Cigarette
More than eighty percent of the nicotine in tobacco smoke is said to be removed by a filter pipe recently announced. Smoke drawn from the pipe bowl to the mouthpiece passes through two halves of a cigarette, which act as filters to absorb most of the nicotine.
U.S. Navy Blimps Learn New Role for Sea Rescues (Mar, 1940)
Seems like that would be a pretty slow rescue…
U.S. Navy Blimps Learn New Role for Sea Rescues
With the aid of new airship inventions, U. S. Navy blimps can now “anchor” ” 100 feet above the sea, and pick up ill sailors or victims of shipwreck. A circular disk called a “drogue,” dropped into the sea at the end of a cable, keeps the craft’s nose pointed steadily into the wind.
Old Tires Rolled Into Lump Make Odorless Fuel (Jan, 1932)
This seems like a bad idea to me.
Old Tires Rolled Into Lump Make Odorless Fuel
HEREAFTER you need not worry about the disposition of all your old auto tires, for believe it or not you can make use of them as fuel. After you have gathered up a number of discarded tires proceed as follows: Take a sharp knife and cut a slash in the side wall just about an inch above the bead, which should then be removed. Then cut the tire crosswise and roll it up as if it were a carpet or rug and tie it securely around the center with a heavy piece of wire. Place this roll in an open fireplace and you will have an intense heat for about four hours, and there will not be the slightest smell of burning rubber. Two or three rolls at a time will easily keep a fair-sized room comfortably warm.â€” Edward Sievers.
“Night Glasses” Train Soldiers To Fight in the Dark (Dec, 1940)
Learn how to shoot while wearing a welding mask!
“Night Glasses” Train Soldiers To Fight in the Dark
For practice in fighting in the dark, cadets in a British officers’ training unit wear special “night glasses” during daytime maneuvers. Fitted with dark lenses, the glasses reproduce the visibility conditions that would be encountered at night. In this way, the young soldiers learn to recognize the landscape as it appears in darkness, and acquire skill in taking “pot shots” when they cannot see their rifle sights. In the photograph above, several cadets are using the glasses which turn day into night.
