Abstract: A nursing brassiere that provides added support and yet can be easily manipulated to provide nursing access is disclosed The brassiere has overlapping frontal portions each with a cup-like configuration for covering the wearer's breasts. The frontal portions are attached to a lower elastic or elastic type cut and sewn portion below the breasts which includes a wrap-around band. Along a lower outer border of each cup-like frontal portion is a relatively short arcuate wire member that provides breast support under normal wear conditions. When nursing takes place, a frontal portion is easily pulled aside to displace the supporting wire and expose the breast for the necessary nursing access.

Abstract: An earth drain comprising a core consisting of an elongated flexible web having on at least one surface thereof, and preferably on both surfaces, an array of discreet projections spaced transversely across the width of the web, and longitudinally in the lengthwise orientation of the web. The array of projections is interrupted by a plurality of elongated projection-free zones extending in the longitudinal direction of the web, and spaced transversely across the width of the web. A filter of sheet-like water permeable material encases the core, and is adapted to be maintained in spaced relationship to the web by the free ends of the projections thereon.

Abstract: A liquid filtering apparatus comprises upper and lower platens and a plurality of intermediate plate members between the platens. When pressed together with a sheet of filter media between each pair of adjacent plates, a fluid-tight chamber for incoming liquid to be filtered is formed on one side of the filter media. When the filter media requires replacement, the upper platen is lifted to separate the plates. Each plate is provided with combined alignment and stop means so that when the plates are again brought together after renewal of the filter media, they will automatically resume their normal stacked position in proper alignment, the stop means also providing a preselected amount of space between adjacent plates to cause a desired amount of compression for a sealing member between the plates. The alignment and stop means is designed to absorb the compression load on the plates, thereby enabling them to be made of lighter metal or plastic materials without overstressing their side walls.
