Sir: May I ask when the name of element No. 61, illinium, was changed to “prometheum,” as given on p. 143 of PS for October? Element No. 61 was discovered at the University of Illinois in 1926 and so received its name. Students of physics and chemistry who matriculated a few years ago may have to learn all over again to satisfy some screwy professor of physics.

Already, full-size missiles have reached Mach 7 (the Wac Corporal-V-2 combination did slightly better than that last year).

HERE’S modern design in oak and glass—a sleek coffee table that you can build with hand tools. It’s stout and expensive looking, but the materials cost me only $18. One of its features is the double-life top. The glass bricks are tough, but even if one is broken, you can just turn it over and you have another perfect top.

DOES your youngster hang his towel on the bathroom floor? This little trainer will make it easy for him to remember where the towel belongs. Draw a grid of ½" squares and copy off the pattern above line for line. Next trace the outlines onto a ¼" by 7" by 17" piece of plywood or hard composition board.

TURNING a window inside out to clean the outside inside may sound like double talk. But that’s exactly what you can do with this kit invented by Fred Roth, of Brooklyn, N. Y. The bottom halves of the inside stop and parting strip on each side of the casing are cut out, joined by metal strips, and screwed back in place.

John Modroch
When a closet and bed share the same wall, this type of combination fixture can light up two dark spots with one bulb. To install a unit of this kind, it is necessary to break into the wall. Most of the damage, however, can be limited to the closet side; so if a seam shows in the patched plaster, it won’t make much difference.

DO YOU have any fine hardwood scraps that are too good to waste and too small to use? You can put them to work by making this expensive-looking tray. It’s built up in sections from small pieces. It isn’t even necessary for all the wood to be of the same kind, because you can get many interesting arrangements by putting dissimilar pieces side by side.

THREE flashlight batteries will spin this “two-cylinder” reversible engine at a merry clip. Fed 10 or 12 volts, its unusual “rocking-beam” action will develop enough power to drive toys or window displays. The crankshaft is a brass rod, pointed at both ends, that runs in pivot bearings.

SMALL pieces of linoleum left over from a job can be used crazy-quilt fashion for covering closet floors, shelves, basement steps, and other areas where the pattern and number of seams aren’t important. Mottled linoleum is particularly good for such jobs because there’s no pattern to match up.

UNTIL you’ve used an oscillating sander, you won’t realize how good drum sanding can be. With this rig, the drum not only rotates but moves up and down across the work. The result is that it forms no ridge marks and produces a much smoother finish.

HOW much work is it for your wife to prepare your breakfast? If your kitchen is as inefficiently arranged as most, she probably makes at least twice as many motions as necessary. And, since that proportion holds for most of her daily kitchen operations, she ends the day about twice as tired as she should be.

Lathe Subs as Sander. If you lack a regular sander, a substitute can be assembled from a sanding belt, a flat pulley, a length of plank or two-by-four, and a couple of clamps to hold the rig to the bed of the lathe. A large chuck serves as the drive pulley.

IF ALL lathe work had to be turned between centers, it would be hard to make bowls and trays, since the tailstock center would be constantly in the way. For work like this the faceplate is ideal. It’s a metal disk, driven by the headstock spindle, to which work can be directly screwed, eliminating the need for tailstock support.

ODORLESS PAINT.—something many home decorators have wanted—has been put on market by Keystone Paint Co., Brooklyn. It contains a highly refined petroleum thinner instead of turpentine. Oily binder also has been deodorized. YOUR BLOOD can be tested for diabetes, anemia, syphilis, RH factor, and type in a trailer built for the U.S. Public Health Service.
