Machine Speeds Bottle Returns (May, 1960)

I personally prefer those machines that shred your cans, but none the less, an origination.

Machine Speeds Bottle Returns

At least one waiting line might be shortened if a supermarket installed this bottle-return machine in its parking lot. You’d slip bottles into sized openings. The machine would calculate the refund, issue a slip, and move the bottles inside on a belt.

Tanks Simplify Bullfrog Culture

COMPLETE protection against all natural enemies, perpetual shade, adequate feeding, abolition of
cannibalism, elimination of red leg frog disease, ideal temperature control, confinement of frogs to the domestic range, greatly reduced mortality and a growing time of seven months from baby frogs to marketable maturity are some of the many advantages claimed for a patented system of frog culture in concrete tanks developed by John Eugene Stearns of El Monte, California.

Elaine Shepard, Hollywood film actress, could pass for an Indian in war paint when she wears the new standard television make-up. White high-lighting around the nostrils, eyes and hollows of the throat is necessary for good reproduction. Lips, eyebrows and eyelashes are blue-black.

License Plates, now with more Skulls! (Mar, 1939)

I want a skull on my license plate! I also love the girls expression.

Special License Plates Tag Careless Drivers

Special license plates for traffic violators are being considered as a safety measure by Cliff Davis, commissioner of public safety in Memphis, Tenn. If the measure is adopted motorists who persistently break traffic laws will be required to run in their regular licence plates for special tags, similar to that shown in the photograph above, bearing a skull and the words “traffic-law violator.”

Spinning Head Tapes TV at Home (Jan, 1965)

Spinning Head Tapes TV at Home
Is this the year you mate a home TV tape recorder to your TV set? Two European electronics firms – Philips (Netherlands) and Loewe-Opta (West Germany) are now selling TV recorders specially designed for home use. Both will be available here in a few months.

To capture the details of a TV picture, the recorder must have a three-megacycle recording bandwidth. Earlier prototype home TV recorders were essentially scaled-up audio recorders: They achieved wide bandwidth by moving 1/4-inch-wide audio-type tape past a stationary recording head at high speed (usually 120 inches per second). High tape speed leads to excessive head and tape wear, and gobbles up tape at an uneconomical rate.
Both the Philips and Loewe-Opta recorders use one-inch-wide video-recording tape and a rotating recording head. The tape is threaded in a single spiral around a slotted drum that contains a spinning recording head rotating at about 3,000 r.p.m. Tape speed around the drum is about six inches a second. The rotating head records the TV picture signal on adjacent diagonal bands on the tape. The audio is recorded along the edge of the tape.
Both units are expensive-over $2,000 with accessories-but cost should drop as sales rise.

Pump Your Own Gas (Dec, 1939)

Pump Your Own Gas
If you’ve ever run out of gas late at night when gas stations were closed, you’ll appreciate this latest wrinkle in gasoline dispensing – the “Gasoteria”. The motorist drops coins into slots in the tank and may deliver gas directly into his car without the aid of an attendant. Should the tank be empty his money is returned automatically.
