The reliable sealing performance of Conflact flanges is a result of the design and geometry which "Captures" the gasket material. When the conical sealing knife edge of the flange is pressed in to the flat OFHC copper gasket, a lateral cold flow of the gasket material occurs. This cold flow is limited by the vertical flange wall.

Further material flow away from the seal area is severely limited and high interface pressures are developed. These pressures cause gasket material to fill surface imperfections and produce a highly reliable seal. At high temperatures, the "Capturing" Geometry maintains high pressures despite softening of the gasket.

The 3II Whole Body Consumer Commissioned At
(NATIONAL INSTITUTE OF NUTRITION HYDERABAD)

The new whole Body Monitoring Facility for low level counting set-up at NIN opens up a new phase of research activity at the Institute with a wide range of potential applications. The new facility is a 3II counter where the subject/patient is counted in a stationary geometry under low level back ground condition in a steel room and an efficient ventillating system.

Steel room : The detectors of the WBC facility are set up in a steel room. The steel room is housed in an air-conditioned hall of dimension 6½m x 5½ x 5 meters. It is erected on a special platform reinforced with concrete and MS plates. It has dimension of 2 x 2.7 x 2 meters. The steel thickness on four sides of the wall (including door on one side) and top is 150 mm and at bottom it has a thickness of 225 mm. All the construction materials, like Steel, lead, copper, sand, brick, cement were tested for their low background and approved by BARC for their acceptability. Inside the steel room, there is a 10 mm layer of lead bricks fixed to steel plates. Over this lead brick is one mm thickness of copper sheet layered around. The various thickness of steel sheets were washed with distilled water and coated with "suprap" an anti-corrosion agent. The joints are argon welded. The door mechanism of the steel room is erected on special rails and the doors are supported by Taylor bearings imported specially for this purpose. They slide on a stainless steel rod. The door can be slided either way and it is easy to handle. A manually operated door system was preferred to avoid any emergency situation in the case of an electrically operated doors due to power failure.

Mechanical Attritor shall be used for grinding of metal powder. It consists of a water cooled vessel with an armed shaft. This  shaft assembly is rotated with the motar- gear box. After completion of grinding operation ground powder can be taken out from the bottom in a container
