  • Patent number: 9744642
    Abstract: A slurry feed system includes a valve manifold, a mixing tank, a slurry feed pump, a surface tension meter and suction piping, discharge piping as well as slurry return piping. The valve manifold includes inlet piping, outlet piping fluidly coupled to the inlet piping, and a slurry discharge header for supplying slurry to CMP stations. The slurry feed pump is connected to the mixing tank by the suction piping. The discharge piping is routed from the slurry feed pump to the inlet piping of the valve manifold. The slurry return piping is routed from the outlet piping of the valve manifold to the mixing tank. The suction piping, the discharge piping, the inlet piping, the outlet piping and the slurry return piping define a first slurry supply loop. The surface tension meter is coupled to the first slurry supply loop.

  • Patent number: 6994606
    Abstract: An adjustable brassiere is provided with a first adjustable buckle fastener in the middle of the interval between the two cups and second adjustable buckle fasteners in the middle of side-straps linking the two cups. Two ends of each adjustable buckle fastener are designed with two slits and a serrated cut adjacent to each inner slit. First adjustable straps extend from the two cups in the interval therebetween and are adjustable coupled to the first adjustable buckle fastener. Side-straps of the two cups include two sections from which second adjustable straps extend. The second adjustable straps are respectively adjustably coupled to the second adjustable buckle fasteners.
