Abstract: An apparatus for holding x-ray cassettes and grids in which any grid of a specific length and width can be combined with any cassette of a corresponding length and width without regard to the cassette thickness. The apparatus includes a frame assembly having side rails with flanges and a back rail with flanges which form two channels, one for the grid and one for the cassette. The cassette channel is dimensioned to accept any thickness of cassette. Parabolic springs are located within side rail cassette channel portions to bias the cassette against selected flanges. Locater members are also provided to properly align the grid and the cassette.

Abstract: A plurality of elongate absorbent pads, each of approximately circular cross-section, are arranged parallel to one another in a pyramid shaped bundle, with a first layer of pads arranged in parallel, side-by-side relationship, the layers of pads above the first layer of pads arranged in side-by-side relationship and overlying the layer of pads next below at positions over the adjacent surfaces of adjacent ones of the pads in the layer next below. The pads are movable with respect to one another, a liquid pervious tubular sock surrounds and encloses the pads, a sheet of liquid impervious material substantially covers the bottom portion of the first layer of pads, and a layer of adhesive material is disposed on the bottom portion of the napkin for securing the napkin to an undergarment.
