Batteries Propel Unique Car (or Pipe Line Inspection
I EAD-ACID storage batteries have come to the aid of 1 the Los Angeles Bureau of Water Works and Sup
ply in developing an ingenious device for inspecting enamel coatings on the interior of water mains. The device consists of a three-wheeled car just large enough to carry an inspector through 36 in. pipes. On the front of the car, a number of steel brushes, electrically con nected, are mounted. These brushes make contact with the enamel surface and when they pass over spots on which the enamel coating is too thin or defective, they spark. These spots are marked and later painted to give
adequate protection to the pipe against corrosion. Power to propel the car and for the brushes, and to
light a search-light which shows the way, is provided by two 140 amp. hr. lead-acid storage batteries. Thus by the aid of these dependable batteries it is possible to inspect the miles and miles of large underground TMin that supply Los Angeles with water.
Lead-acid storage batteries are found to be useful by many engineers with perplexing problems. They en able dependable power to be brought to many inacces sible locations without expensive wiring. They are safe when external power sources might be dangerous. Leadacid batteries can deliver large currents for short times, as in automobile starting batteries, when such is the demand, and are particularly useful in emergencies.
Red Lead and Cork Prevent

Condensation on Metal
ONDENSATION on pipes and other metal sur
C faces may be prevented by covering them with a mixture of red lead and cork. After this protection is provided, final coats of paint may be used to obtain the desired decorative effect.
Red lead paste for this purpose is thinned only slight ly so that it has nearly the consistency of paste. A mix ture in the proportion of 100 lb. of paste red lead to % gal. boiled linseed oil is about right. If raw oil is used instead of boiled oil, 1 pt. of drier should also be included. After the metal surface to be covered is thoroughly dried and wire brushed, the red lead is applied to a small area. Finely ground cork is then thrown against the wet paint or applied in other con venient ways. Other small areas are treated successively in this manner until the whole metal surface is covered.
After this first coat of red lead and cork has dried, two coats of white lead paint, tinted as desired, are brushed on. They should both be mixed in the propor tion of 3 gal. raw linseed oil and 1 pt. drier to each 100 lb. of soft paste white lead. If the finish is to be dark, these last two coats may be red lead, tinted and mixed to ordinary brushing consistency.
