T* major requirement* far the new i laboratory building influenced in de sign and conitructton: exhaust hooda a each laboratory and a conlinuoua supply of conditioned air. i In the Anal design the exhaust hoods "ere connected bi ducts running up the tide of the building to fin rooms on the i penthouse. This design preserved inter nal laboratorr space and incidentally, give tbc building a distinctive appear ance. To provide the continuous change of i air in laboratorirs the architects deemed it necessary to totally enclose laboreiory spaces from fluor to slab. The presence oi nun roue pipes, dacte, and rlactncal conduits in the ceiling area of each laborstort made the erection of a solid partition from Boor to slab too costly. Instead, the partition contractor rec ommended the use of a l-lb,, i i/64-in. thick) sheet lead plenum barrier bung from the soffit of the floor alnh to the lap of a ceiling-high partition construc i i tion below. Building architects approved the pro i posal because it had several benefits. It would lightlr enclose the plenum apace, thrrebv making the space an eflactirt air chamber. It would seal off noise from the id) acme laboratory. It would be the least expensive and moat effective method in trrma of construction, since sheet lead is easily cut, fitted, and formed tightlv around penetrations. inert lead was supplied in roll* mea suring +-ft by 2i.fl. long- Deb roll was cut into sheets of required length, nd is it waa hung, slits were made to permit the passage of piping. After tbo sheets were in place, the slits war* folded back around the piping and sealed to maintain an antight mem brane Because installation wea nude after piping was already in place, it was far easier and chenper to install the sheet lead than te meaaurt, cut and fit a rigid partition to the dab.

CAMERA EYE LEAD PLAYS A JAMES BOND ROLE Modern espionage baa become so sophis ticated that "spies" arc now using x-rays to read the combinations on safes and security desks. The Governmeat of Creel Britein hea found a way to fo9 the rillaina. Lead-coveted tumblers arc being substituted for regular ones in all high security areas. Lead, of course, is impervious to the a-rays and makrs the safes ``eraek-praer. Tha problem is serious enough and the solution so effective that SI million is being spent on the conversion of the tumblers. VO la this novel application, a lead weight ecu aa the camera shutter actuatorAnchor .Alloys. Inc., worked with the engineers of Simpro Corporation of America to develop a rpccial lead weight for the pocket sire 5impro-X cuncn. The tiny lead actuator weighs only II grams and is produced by a low cost casting process. The Simpro-X is small and simplified; easily slips on to any silt 126 film cartridge rather than the cartridge ima the camera. It will Uka an x-cube flush and color pictures.
