Electrons Go To Bed (Jan, 1947)
Electrons Go To Bed
NO MORE clammy sheets. No more ice in the bed. No more flannel pyjamas. No more cold feet. No more midnight shivers looking for more covers. No more! The Electronic Age has produced the Electronic Blanket.
The electronic blanket looks like an ordinary woollen one of good quality, but hidden inside there’s a pair of flexible wires that go up and down and all around. One is a warming element, the other a temperature “feeler” that governs the degree of warmth of the blanket. Operation is automatic, through a small bedside control.
When set for, say, 81 degrees, the feeler wire lets the blanket come to that temperature, then sends an electronic impulse to the control, causing it to cut off the current. When the temperature falls a degree the feeler causes a resumption of the warming flow. Soâ€”the warmth under the blanket is kept uniform at the temperature you preselect, no matter how the room temperature may change during the night.
It’s all the cover you need. It’s foolproof. It’s launderable. It was developed by the Simmons Company, who want us to be comfortable in bed on cold nights.
