Rack Protects Food from Poison Gas

Supplies of food and drink can be protected from contamination by poison gas in case of wartime air raids by a novel and inexpensive device developed by M. Jaffe, a British inventor living in Liverpool. Food is placed on a raised wire platform and covered by an inverted mixing bowl, bread box, roasting pan, or other nonporous kitchen utensil. By means of two long wire handles, the covered food is then lowered into four or five inches of water standing in a basin or in the kitchen sink. The water forms a perfect air lock inside of the improvised food protector, making it impossible for gas fumes to seep in. With the device, it is said, one minute is sufficient time to protect a supply of food which could be consumed without fear of contamination or pollution after the danger of the gas raid had passed. Larger units could be used for protecting food in hospitals and other institutions.

Super-Windmills

Plans are being made to harness mankind’s oldest and cheapest source of power for industry by means of huge aerogenerators.

By Frank Tinsley

THE next few years may see a decided change in the landscape of our country. In certain strategic places which promise a constant, strong wind such as mountain passes, will grow strange structures resembling the Martian machines of H. G. Wells. But these will be instruments of construction, rather than destruction —tall, steel towers supporting fans to convert wind energy into electrical power.

ROBOT PLOWS WHILE FARMER RESTS
While its owner sits comfortably on his porch, a new farm tractor operated by radio control plows his field for him. Radio impulses governing the tractor’s movements are supplied by an automatic radio transmitter, and are picked up by an antenna on the tractor. A receiving set starts the tractor’s engine, works the throttle and controls the steering.

This method is also very effective for finding gasoline leaks. When you you notice the jet of flames, you’ve found your leak.

Cigarette Smoke Finds Leak in Inner Tube
A burning cigarette can guide you in locating a leak in an inner tube, in case it is not convenient to dip the tube into a tub of water. The cigarette is moved around the surface of the inflated tube, until the air jet from the leak deflects the rising smoke. Make sure, before using this method, that there are no strong air currents in the room where it is being done.—R. B.

Automaton Foils Hat Rack Thieves

THE thief who runs off with hats and coats on hat racks must find another place for his trade than the Anhalter station in Berlin, Germany. A burglar-proof hat rack automaton, now in service in the station, makes theft of clothing impossible. The automaton, shown in the picture below, is very much like an ordinary hat rack. The guest hangs his coat, hat or umbrella on the rack, drops a coin in the slot and his clothing is safe. He receives a key with which to unlock his clothes when he wishes to leave the station.
