REAL ESTATE. CHEMISTS' WORK HELPS BUILDING New Construction Aids Are Shown at 15th Display in New York. New chemical products which will aid the building and construction tndustry are featured in the Ameri- can Chemical Society exhibit called “Children of the Recovery,” first shown at the Fifteenth Exposition of Chemical Industries in New York, De- cember 2 to 7. Like the “Children of Depression” display of the society two years ago, the exhibit, it was pointed out, illus- trates the essential role played by research in stimulating business re- vival. Hundreds of products devel- oped in the laboratory during 1934 and 1935 are now manufactured on & commercial basis and are finding wid- ening use in industrial activity. Cements, paints, dyes, lacquers, resins, metals and plastics have been improved through recent scientific effort. A bright zinc which forms a low-cost, decorative, rust-resistant coating makes attractive finishes that do not tarnish or show fingermarks. It can be produced on steel surfaces by a new electro-plating process in thicknesses up to three-thousandths of an inch. Cement Increases Strength. A cement especially suitable for use with acid-proof brick strengthens a structure so much that no other metal shell is needed. It is low in cost, has no upkeep expense and does not cor- yode. It is based on plastic sulphur and has superior bonding strength and resistance to thermal and mechanical shock. A sister product is suitable for producing bell and spigot joints which are permanently leak-proof, vibration and temperature resistant, and cheaper than lead joints. New casein paint in paste form yields a film which does not discolor or show the effects of water, wear and weather. It is valuable for painting cement and plaster surfaces. A pro- cess of manufacture of zinc sulphide results in a white pigment of remark- able strength. It is recommended for its excellent dispersing and suspending properties, its tint-holding power in paints and plastics, and its freedom from acidity in rubber. Smooth surfaces on sprayed lacquer coatings are secured without sanding by removal of all moisture during the manufacture of the lacquer. Amyl elcohol is used to dehydrate nitro- cellulose before it is made into lacquer. A non-flammable cellulose suitable for protective coatings and molded plastics is cellulose nitoracetate. A white odorless, fluffly material which produces clear solutions when dis- solved in organic liquids, it is said to surpass cellulose acetate in moisture resistance and in film properties. Ethyl Cellulose Has Advantages. Ethyl cellulose in a white granular form has important advantages for paints, lacquers and plastics. It is stable in light and non-flammable. By emulsifying nitro-cellulose lacquers both clear and pigmented, in water, otherwise unsprayable lacquers can be sprayed. Emulsification reduces fire hazard and cost by minimizing the proportion of expensive solvent re- quired. It allows application of lacquer to porous surfaces, such as paper, plaster, cement and other building materials, without requiring pre-treatment of the surface. Thus emulsification opens new and im- portant flelds to lacquers. Ancther paint ingredient is cellulose aceto-butyrate, from which lacquers are made that will not discolor, dis- integrate in the sun, or absorb moisture. It produces clear, flexible, tough films that will adhere tenaci- ously to metal. Its properties suggest its use as an overcoat for outdoor exposure, as on signs and filling sta- tions, as well as in clear coatings for the protection of polished metal, hard- ware, ornamental iron, and other architectural materials where weather exposure is encountered. Paints formulated with ethyl silicate, which is employed as a preservative for the hardening of stone and in arresting decay and disintegration, are unaffected by heat and are suitable for coating furnace castings. Mixed with siliceous powders, the silicate forms weather and acid-proof mortar and cements as well as refractory bricks and other molded objects. A synthetic resin finish, neo-spectra, exemplifies & new principle in the surface chemistry of carbon black. Whereas ordinary high intensity color blacks are difficult to wet with syn- thetic resin, this substance is vehicle- seeking instead of vehicle-repelling. It has been widely adopted in the fleld of resin enamels. - Resins Thermoplastic. Plastic resins derived from a lignin ‘base exhibit remarkable thermoplastic The property at 2601 Connecticut avenue, shown in the top photo, which at one time housed the Lega« tion of El Salvador, and more recently was the Kaleidoscope Restaurant, will be razed to make way for the group of shops showri in th¢ lower photo. ‘The new building will be erected by Dr. C. Augustus Simpson. The C. H. Hillegeist Co. are to be agents for the property. Plans and elevations, prepared by Jarrett C. White, architect, have been approved by the Fine Arts Comm ission. properties. Either alone or mixed with other more expensive resins and in- corporated with fillers, this resin pro- duces boards, sheets and a variety of molded pieces. Paints, emulsions, binders, adhesives and plastics of exceptional chemical resistance can be compounded from tornesit, & chlorinated rubber base. 1t is an odorless, white, fluffy material, non-flammable, impermeable to water vapor and with good dielectric prop- erties, It provides unusual protection against rusting of steel. Eyestrain and fatigue from glaring highway surfaces can be eliminated by tinting the concrete with a pure colloidal carbon black suspension. Since the color is a gray and not a black, there is no harmful effect on night traffic and in fact the reflection of oncoming headlights is minimized. The material will also dye pavements, flooring and architectural concrete in general. It produces permanently dark colored and attractive concrete streets, sidewalks and driveways and allows uniform color in repair work. A self-polishing wax touches up worn marks on floors, as well as achieving a briliant, hard luster for a surface in 20 minutes. It is adapted to linoleum, rubber-tile, asphalt, hard- wood, composition-tile, terrazzo and marble floors. Because polishing is eliminated, maintenance expense is reduced from 50 to 60 per cent. The floors are not dangerously slippery and the wax will not catch fire. It is non- injurious and contains no grease, oil or petroleum. —_— BUILDING MODERNIZING TO SHOW ’36 INCREASE Higher Volume of Work Will Be Recorded Than in 1935, Survey Reveals. Building modernization will show & far higher volume of work for all types of structures requiring improve- ment in 1936 over the rehabilitation progress accomplished this year, ac- cording to a survey of future possi- bilities just completed by Buildings and Building Management. The survey represents reports from 82 per cent of the office building owners and managers in 143 of the leading cities of the country, and from 95 per cent of the apartment house owners in those cities. Finish for Stained Surfaces. It is customary to finish stained surfaces with varnish or shellac. Two or more coats are generally applied, the number depending upon the finish desired and the wear to which the surface will be subjected. e WAVERLY TAYLOR. % INVITES YOU TO VISIT The New American Home 0[[2!7W00¥ Furnished and Decorated by ‘WOODWARD & LOTHROP THIS HOME, SPONSORED BY THE GENERAL ELECTRIC COMPANY, IS AN ELECTRIC KITCHEN HEALTH HOME, INCLUDING 6.

BY LILLIAN COX ATHEY. OU are looking at Margay (an- other name the tiger has) manicuring her nails. By the looks of the bark you can see she patronizes this “besuty parlor tree” often. Her home is in the for- ests from Mexico to Paraguay. It is very difficult to give you a definite color pattern or arrangement of stripes or rings by which you could identify her, for there is much indi- viduality in this family and they pre- fer to be different. One thing they all have is coarse fur of a dull, grizzled color, and it is dec- roated with black spots or rings. The handsome tail carries out the color pattern, though it never has rings on it. Margay is not so very much larger than a p;i tomcat. She is 24 inches long, with 11 inches addi- tional for the tail. She is an expert climber, as are all cats of the forest. They love to resort to places where it is almost impossible for a foe to fol- low them. Like our own tabbies, they love to loll in the sun, and in se- cluded spots upon a wide, comfortable tree limb they take the “violet ray” treatment. ‘The mothers establish their nur- series in great hollow trees or deep fissures of rocks. Here the quad- ruplets or quintuplets are born. Could you see the tiny infants, small, CHEVY CHASE CORNER soft bundles of fur, you could not be- lieve that, even at so early an age, they could have so much hiss, snarl and spit in them. Their furry coats, though of silky texture, will almost rise up when a foe confronts them. Never once does it enter their minds to retreat. There is not an atom of fear in them. As soon as they are able to digest hearty food they are taught to stalk birds, rob their nests and consume eggs. Later they become expert in outwitting rabbits and finding little | hiding fawns and such creatures. From all accounts, it is extremely unwise to accept one of these kittens as a gift. Your efforts are likely to be wasted. For some time they seem really to be gentle, after once getting used to being fed and handled, but one can never know when the call of the wild will descend upon a little tiger kitten; then watch out!
