Avid golfer...

A couple met at Myrtle Beach and fell in love. They were discussing how they would continue their relationship after their vacations were over.

"It's only fair to warn you, Linda," he said. "I'm a golf nut. I live...eat...sleep...and breathe golf."

"Well,..." Linda said, "Since you're being honest, so will I. You see, I'm a hooker."

Compared to the existing carbon-zinc dry-cells, it offered an appreciable increase in life-span and efficiency during heavy continuous drains. Its construction used an alkaline electrolyte, manganese dioxide as depolarizer, a zinc powder-gel anode, and certain additives such including mercury and electrolyte-creep inhibitors. The patent gave practical details for commercial production. The patent claimed that whereas four cells in series of the carbon-zinc type gave 4.5 volts to power a 1.25-amp bulb for 45-min to 1-hr, the new alkaline design gave good brilliance after 6 to 7 hours.«
