    Abstract: A roll-up fold-up sluice apparatus for use in separating sediment by water flow. The apparatus includes an elongate flexible mat having formed, in a central portion therein, a plurality of longitudinally spaced riffles which extend laterally with respect to the mat's long axis, and which define associated ridges and channels on the mat's upper and lower sides, respectively. The riffles are longitudinally spaced by increasing increments progressing in one longitudinal direction in the mat and are sized and shaped to accommodate a regular ridge-to-channel nesting when the mat is rolled up in that direction. A pair of flaps joined to opposite sides of the mat's central portion can be folded between folded-up positions to form the sides for the apparatus, and folded-down positions to enable rolling up.

    Abstract translation: 一种用于通过水流分离沉积物的卷起折叠式水闸装置。 该装置包括细长的柔性垫，其中央部分中形成有多个相对于垫的长轴线横向延伸的纵向隔开的间隙，并且在垫的上侧和下侧分别形成相关联的脊和通道。 通过在垫中在一个纵向方向上进行的增加的增量纵向间隔开，并且当垫在该方向上卷起时，尺寸和形状适于容纳规则的脊到通道嵌套。 连接到垫子中部的相对侧的一对折片可以在折叠位置之间折叠，以形成装置的侧面，以及折叠位置以便卷起。

    Abstract: A riffled ore concentrating table of the reciprocating type is connected to a table support by ball bearings. The table support has one of its edges pivotably connected to one edge of a base member and the other of its edges supported by the other edge of the base member in a manner such that the elevation of one edge of the table may be adjusted with respect to the other edge of the table.
