ELECTRIC LAMP NEARLY FIFTY YEARS OLD
A DRAMATIC moment in the history of modern illuminating science is pictured in the photograph below, showing Thomas A. Edison and his assistants testing the first incandescent lamp bulb at Menlo Park, N. J., on October 19, 1879.
An Extra Quart of milk in Pure-Pak… please
. . . EXTRA quarts are easier to buy in Pure-Pak It’s so much easier to carry extra milk when you buy it in Pure-Pak, your personal milk container. There are no deposits and no “dead weight” glass bottles to carry to and from the store. Pure-Pak takes much less refrigerator space too … and when it’s empty, just toss it away!
Scientists Invent Machine To Discover How Brain Works
THE brain, perhaps the most mystifying organ of the human body, can now be scientifically studied by a new apparatus which photographs amplified “action currents.” Invented by Dr. H. H. Jasper and Dr. L. Carmichael of Brown University, the new machine will permit physicians to study the action of the brain just as the electrocardiograph permits a revealing study of heart action.
Bullets from Same Gun Linked By Camera
PHOTOGRAPHIC evidence as to whether or not two bullets were fired from same gun is irrefutably supplied by a new comparison camera invented by Dr. J. H. Mathews, University of Wisconsin professor and criminologist.
The camera marks a sensational advance of science in the war against crime. By taking pictures of opposite sections of the two bullets being checked, the camera reconstructs a composite bullet of the two sections. The resulting photographic reproduction is enlarged between 64 and 256 times the size of the bullets, permitting positive identification before a courtroom jury.
The camera is really two cameras merging into one at the single plate holder. The bottom camera takes a photo of the base of one bullet while the upper camera registers the top section of the second bullet, the two halves appearing on the print as one.
Bike Pedal Light Warns Motorists
COLORED reflectors designed for mounting on bicycle pedals were recently introduced in England as part of a “safety first for cyclists” movement.
The colored glass crystals, being continually in motion as the cyclist pedals along, glow brilliantly when in headlight beams of approaching cars.
Berlin Installs First Stamp Vending Machine
BERLIN postal authorities have adopted a new invention that promises to be of real help to all. The automatic stamp vending machine which can be attached to trolley wire posts will relieve a long felt need. The photograph shows a customer operating the crank that produces the stamps. How many times have letters been written, only to be carried in the pocket because there was no stamp with which to post it! The Berlin idea is very simple.
NEW EYE TESTER
THIS remarkable instrument, which is in reality a battery of lenses no bigger than a cigar box, enables the optician to secure over one million combinations of lenses almost instantaneously. The London Refraction Hospital which has recently been rebuilt at a cost of $50,000, contains this machine among many others of the same type.
Wow, I think this car marks the point when the “trunk” of a car ceased to be literally a trunk attached to the rear.
NEW TRUNK RACK FOR SEDAN
AMONG the models seen in the great automobile show at Olympia, England, was a Jowett fabric sedan. This car, as seen in the photo below, is completely covered with Jowett fabric.
Instead of equipping the car with a trunk rack and trunk, the luggage space was built within the body. The panel, in the back of the body, lifts out and upward on hinges. The opening thus exposed is large enough to hold a man and not unnecessarily crowd him.
The English motor car indicates the trend of European design.
First Consumer Electronics Show
Plans for new week-long exhibit of home-entertainment equipment
THE WEEK OF JUNE 25 THROUGH 29 will be a busy one for the electronics industry. A week earlier, the annual NEW (National Electronics Week) show in Chicago will keep manufacturers of small electronic parts and components occupied showing their wares to distributors from all over the country.
Fresh (or not so fresh) from that mammoth task, the industry will move to New York into the Americana and New York Hilton hotels for the Consumer Electronics Show—the first national exhibition especially for home-entertainment electronics.
A Breadbox-Size Navigating System
WE’RE all navigators to some degree. Navigating is simply rinding your way from one place to another and knowing where you are along the way. Usually, though, we think of navigating in terms of ships and planes.
Navigating systems have come a long way since Capt. Bligh’s famous 3,600-mi. journey on the South Seas. All he needed was a sextant because all he really wanted to do was get within sight of land. He even might have considered sailing to within miles of a pile of rocks pinpoint navigation.
