COLOR TV FOR THEATERS (Feb, 1952)

COLOR TV FOR THEATERS
PROJECTED color-television pictures of theater-screen size were shown recently at the Colonial Theater in New York City by the Radio Corporation of America in tests that revealed further advances in the RCA compatible, all-electronic color-TV system. The color show, produced in the NBC studios at Radio City, was broadcast on channel 4. This enabled owners of all existing television sets in the area to view the same program in black and white.

Safety Razor (Nov, 1934) (Nov, 1934)

Safety Razor
HERE is a razor which is said to do its job in any shaving position. The blades, coated with a mineral oil, come in a handy cartridge, and it becomes merely necessary to insert a small tab in the side of the razor, move a small sliding grip, and a new blade is automatically inserted into the holder, while the old blade is ejected. The change is instantaneous. Five blades before the cartridge is emptied, a non-shaving blank appears to remind you to purchase new blades.

Water Rocket (Dec, 1955)

Jet-Propelled Rocket. For flights several hundred feet straight up. fill the eight-inch plastic rocket one-third full of water, pump in air (inset) and press a trigger. In flight, water ejected by compressed air makes a visible jet stream.

Early Porsche (Sep, 1953)

Looks like it would be a lot of fun to try getting into that.

New German Sports Car Called 125-Mile-an-Hour Speedster
A recent entry in the sports-car field is this Porsche racer from Germany—a more powerful and faster machine than the model previously offered by the same maker. Power has been boosted from 70 to 80 horsepower and maximum speed, it is reported, from about 110 to 125 miles an hour. Body design has been revamped, too, with the result that the new model has a body a few inches lower than its predecessor.

RUBBER rollers instead of blades on German practice ice skates can be used at home. They are noiseless, will not scratch floor.

Early OCR (Feb, 1949)

Reading Machine Spells Out Loud

Experimental eleetronic device looks at printing and says what it sees — at the rate of 60 words a minute.

SOME time ago, The New Yorker magazine satirically described the invention of a reading machine. “It is obvious,” a fictional Professor Entwhistle was quoted as saying, “that the greatest waste of our civilization is the time spent in reading. We have been able to speed up practically everything. . . . But today a man takes just as long to read a book as Dante did. … So I have invented a machine. It operates by a simple arrangement of photoelectric cells. . .”

A simple arrangement of photoelectric cells that will read a book for you now has been unveiled by RCA researchers. The device looks at printed matter and reads it aloud, letter by letter. It sounds like a radio announcer spelling out “R-I-N-S-O.”

Pocket-Size Wire Recorder (Aug, 1953)

Seems like you’d need a pretty big pocket if that hand holding it is any indication

Pocket-Size Wire Recorder
PERHAPS one of the most sensational units to appear on the wire-recorder scene recently is a complete battery-operated recorder, 6-3/4x 4-3/8 x l-1/2 in. in size. It records, erases and plays back through a pair of lightweight earphones.

The entire recorder fits any average-size pocket, or it can be carried and operated in a fabric shoulder-type carrying case, as illustrated in photo A. Two types of sensitive miniature crystal microphones are available, as shown in photo D. One is a lapel variety and the other is a wrist-watch type worn by the operator in photo A, for making concealed recordings useful in detective work and for checking comments in crowds at shows and similar applications.

This Minifon recorder, made in Germany, is now available on the American market; it is powered with standard miniature A and B-batteries. The motor is driven by a Mallory mercury-cell-type battery pack that sells for $4.25. This provides 24-hour service. The A and B-batteries last for full shelf life. An a.c. power-supply unit also is available for operating the motor from 110-120 volt a.c. lines. Photos B and C are internal and external views of the recording and playback unit. Recording wire is available in spools providing 1/4 to 2-1/2 hours of continuous operation.

Scotch Tape (Jun, 1960)

Origins of the matte Scotch Tape we all know and love.

NON REFLECTIVE TAPE for permanent mending of torn blueprints, maps, books, and other papers is colorless and almost invisible. The Scotch brand tape is made of acetate film with a matte finish that you can write on with a pen or pencil. Unlike other tapes, it doesn’t discolor with age. A 180-inch roll sells for 39 cents. Minnesota Mining & Mfg. Co., St. Paul, Minn.

Breaking the Language Barrier (Apr, 1958)

Very cool, if a somewhat optimistic article from 1958 about machine translation.

Breaking the Language Barrier

Each year, millions of reports on scientific research are published—a big fraction of them in foreign languages. In this mass of Russian, Dutch, Chinese, Hindustani data are clues to H-power, interplanetary flight, more powerful batteries, longer-wearing tires. The trouble is: Too few scientists and engineers read foreign languages. What we need is a machine to read one language and type in another: an automatic translator. We’re trying to build—not one, but several. Engineering problems? Fantastic. Here’s where we stand now.
