New Machines And Gadgets Bulletin Highlights Several Inventions
A list of new gadgets includes a 10 quart insulated picnic basket with fiber plastic walls and repelling coating. a folding sawhorse with pivoting legs. a coal-dust explosion gallery for safety demonstrations. an oil drainer for autos using air pressure. a two legged golf putter that lifts the striking end. plastic dish-washing aprons. and an electronic safety starter for fluorescent fixtures.
Turbojet and Turboprop Power in Modern Planes
Science Service explains turbojet engines compress air and burn kerosene to produce high pressure gases. Some gases drive the compressor while most exit as jet propulsion. The turboprop uses the created gases to turn a shaft and power propellers.
Scale For Civilization Traced Across Old and New Worlds
Dr. Julian Steward outlines a single growth scale for all world centers, from primitive hunting to empire building, applying to Egypt Mesopotamia China and the New World. The report notes arid soils aided farming via irrigation, animal domestication varied, and cycles of conquest followed by regional florescence and trade.

Glass Bubbles Stand In as Heat Insulator Material
Researchers at the Industrial Research Institute of Denver University report millions of tiny glass bubbles formed from borax feldspar flint soda ash and fluorspar to insulate against heat. The foamed glass is sterile water resistant and aims to replace cork in cold transport for foods and medicines.

Milk Diet Could Sustain Life From Birth to Death
Science Service reports experiments showing milk alone, with minor minerals, can support life from weaning to old age. White rats lived to ages comparable to 70 or 90 years in humans, with no solid food beyond cow’s milk. Dr. C. M. McCay notes milk is nearly complete for all life stages and mineral supplementation can address trace elements.

Make More With Your Scale Using Wedges and Beams
A guide explains multiplying a scale’s capacity by using two wedges, a beam, and simple measurements to lift weights beyond a scale’s limit. It covers setting ratios from 10 to 1 up to 100 to 1, aligning the weight over marks, and subtracting the beam’s weight for accurate readings.
Peril to Dogs: Hard Pad Disease Linked to Vaccine Split
Britain reports a new canine illness called hard pad disease appearing with distemper. It causes hardened toe pads and sometimes nose tips, digestive upsets, and fatal fits. A vaccine by Macintyre Trevan and Montgomerie offers protection, though it does not shield against distemper. Cats appear unaffected.
