Chemical Engineering for Home Experimenters
By RAYMOND B. WAILES
HOW would you like to transform your home laboratory into a miniature factory for obtaining useful products from minerals, with yourself as its amateur chemical engineer? You can roast ores to obtain important metals, convert plain-looking stones into sparkling white crystals, operate a rotating kiln, and magically separate wanted minerals from unwanted ones by a flotation process.
You can now buy remote controlled lawnmowers online.
Builds Remote Control Lawn Mower Device
Attaching two electric – motors, an old paint can, a wooden mixing bowl from a kitchen, sundry gears, wires and drive belts to a regulation lawn mower, Alvin Lodge, an unemployed mechanical engineer of Millersville, Pa., constructed a device that enables him to mow his lawn by remote control. As rigged up for its trial run, the mower successfully operated along a cable guide for a distance of 100 feet from the stationary control box shown being manipulated by the inventor.
THESE FOREIGN FILMS…

“Unconventional” recording formats make recovering data from old disks a bit tricky. A problem the Archive Team has been dealing with as they endeavor to preserve roughly everything that has ever been stored. Ever.
The MD-4 computer mini-disc unit from IMSAI (14860 Wicks Blvd., San Leandro, Calif. 94577) uses conventional Micropolis drives, but unconventional 1024-byte-per-sector recording format. Result: an 18-percent—780K bytes-increase in storage capability. It’s $1995 with MDOS and controller.
NEW MOTOR FOR AERIAL NAVIGATION.
A RECENT development in gasoline engines promises to overcome in a measure two drawbacks to aerial navigation—the weight of the engine and the instability of the machine as a whole. In the new engine the cylinders revolve and act as a comparatively heavy flywheel, whose gyroscopic action tends to keep the machine in equilibrium.
Enough Bread for an Army
FRESH BREAD daily for 96,000 soldiers, more than double the old equipment’s capacity, is turned out by the new mobile bakeries developed by the Army’s Quartermaster Corps. Each bakery company, with three mixing and make-up trailers and six oven trailers, can now produce the two-pound loaves at a 20-per-minute rate.
Inflated Owl Decoys Crows
Crow hunters have been supplied with an unusual accessory in the form of an eighteen-inch pneumatic decoy owl, which can be carried rolled up in a coat pocket and inflated when needed. Crows are hereditary enemies of owls, and attack them whenever they find them in daylight. Hence, the decoy placed on an upright stick in an open space attracts the crows and brings them within gunshot. The body of the decoy owl is made of heavy, durable canvas which is painted realistically.
