Turntable Swings Autos To Pumps In Rotary Gas Station
A NEW type of filling station that uses a turntable to whirl automobiles around a center service island was recently opened in New York.
The service island is set in the center of the turntable and consists of an enclosed office with three separate pumping units to dispense gasoline, oil, air, and water.
Turntable for Narrow Streets
TRAFFIC experts of Paris have found it necessary to install automobile turntables in certain of its narrow streets so that cabs and autos may be turned around without having to go miles out of their way to find turning places. Mounted on roller bearings which offer but little friction resistance, these turntables are easily operated by turning a hand-crank situated on the curb which is connected to the center post.
Aircraft Turntable Checks Compasses
Aircraft compasses can be quickly checked for accuracy and any errors corrected with a compensator that is embedded in concrete at the airfield. The old method of compensating a compass was to maneuver the plane to definite headings on the ground which were determined by reference lines from a compass rose painted on the field. The new compensator is a bowl-shaped disk free to turn on a base plate which contains a compass rose dial. The aircraft is headed approximately north and one wheel rolled onto the turntable. The plane then is rotated until the heading is magnetic north. With a pointer set at zero, the directions are determined by swinging the plane until the pointer indicates the desired reading. The compass is then compensated for error.
Turntable Eases Garaging
Now Frank Enos of Sausalito, Calif., just presses a button to solve what had been a difficult problem. He lives on the side of a hill, with a garage 30 feet below the level of the road and at the end of a 150-foot driveway. Backing up the hill on wet mornings was sometimes a dangerous chore, until Enos devised a turntable and installed it just before the entrance to the garage. Pressing a button puts a 1/2-horsepower geared motor to work revolving the table after Enos backs out, and he drives forward up the hill. The turntable deck is supported by 4 by 12-inch girders and 2 by 12-inch joists which are set on eight concrete piers.
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.
I’m pretty sure this thing is hanging off the side of a building in Manhattan right now.
GIVING THE THRILLS OF AN AEROPLANE
A NEW form of amusement park device that takes the thrill-seeker aloft in circling swoops has been installed on the “Zone” at the Panama-Pacific International Exposition. The device consists of a steel arm, nearly 250 feet long, which is pivoted at one end, and carries a car for passengers at the other. The whole mechanism revolves on a turntable, so that as the arm rises, the car is carried around in an ascending spiral.
