Snow, sleet, rain and high winds add to the rigorous demands of nature in this area. Lead was chosen by architect Flick both because it could provide eco nomical and dependable protection against seepage and damage due to water and snow and for its aesthetic contributions.

Operation of the stud driver is ex tremely simple and safe and does not require a skilled operator.

The use of super voltage X-ray does not replace me dium voltage therapy in the majority of cases, but patients for whom super\oitage therapy is indicated derive advantages from these well defined, penetrating X-ravs that are not ob tained with conventional X-rav equip ment. The deep therapy room is on the ground level of the Swedish Hospital and has walls and ceiling of concrete up to 4 ft. thick. The entrance to the room is a 4 ft. x 7 ft. opening in the concrete. To effectively seal the aper ture from stray radiation a unique lead door was designed. Measuring 6 ft. x 9 ft., the door was constructed by joining to each side of a 1 in. mild steel plate a sheet of lead 34 in. thick. In turn, the lead was covered with a 3/16 in. steel plate. Since the weight of the door then totalled 9.000 lb., it was designed to slide on a 90 lb. railroad rail. Pow'er operated bv a 34 h.p. motor, the door rolls on stand ard ball-bearing pillow blocks at a rate of 4 ft. in 20 secs. The leading edge of the door is. of course, pro tected with a safety device to prevent anvone being caught as it closes. In ase o' oower failure, the door can be hand operated. The door was de signed bv G. A. Pangborn. consulting engineer of Seattle and built by Pacific Steel Products Co., also of Seattle. Behind the machine is the control room where the operator looks through glass that could almost be called trans parent lead, since it analyzes 75% metallic lead bv weight. This remark able glass, called Hi-D and developed only recently, is endowed with a high refractive index, permitting extreme wide angle viewing, and exception clarity.

J. are subjected to the rigorous environment of heavilv industrialized area plus a sea air atmosphere. Protective coating of the equipment puts exacting require ments on the paints used to withstand successfully the dual corrosive condi tions which are in addition to the ordi nary effects of weathering.

TT-P-86a. Type II. The job was then finished with a top coat of aluminum paint. Particular benefits result from this .-vstem. Excellent wetting is achieved with the first coat of Type I. which is a straight red lead-linseed oil paint. Even over rusted surfaces this charac teristic will implement a first line stop page to corrosion by the red lead pigment. The second coat. Type II. which is a red lead mixed pigmentaikvd varnish-linseed oil paint, is a faster drying paint which allows quicker recoating and consequent re duction in scaffolding time.

The manual is written from the paint user's viewpoint and is an ency clopedia of paint systems and practices that are most widely used by industrial steel producers and consumers. The paints are designed to give the greatest protection at the lowest maintenance cost. Copies of "Good Painting Practice" may be secured at $6.00 each, postpaid, from the Steel Structures Painting Council, 4400 Fifth Ave., Pittsburgh 13, Pa.
