A cabinet drawer () for storing information modules () of selectively different widths in rows extending front to back of the drawer has row dividers () which are removably end mounted within slots () at any desirable width spacing. The dividers each have a flexible center portion () terminating in pedestals () for receipt within the slots (). When dividers are so-mounted within a drawer () they are secured in place by inherent spring characteristics of the divider ().

Infinitely adjustable module row divider for a cabinet drawer

An information module storage case ( ) include a plurality of storage shelves ( ) of varying spacing to accommodate modules ( ) of different dimensions. A shelf base ( ) has opposite ends configured for locking receipt within openings in interior sidewalls ( ). Channels ( ) extend between the base ends and accommodate spring wire end locators ( ).

Modular storage case and adjustably variable shelving therefor

A method and apparatus for monitoring density fluctuations in a spiralling flow within a hydrocyclone. The invention involves the use of a nuclear density gauge which directs a beam of radiation asymmetrically across the hydrocyclone away from the centrally located air column. This air column within the hydrocyclone is created by the spiralling or cyclonic action of the flow and exists when the hydrocyclone is in operation. In a preferred embodiment, the flow is particulate solids in a carrier liquid such as water which has a substantially constant specific gravity so that the fluctuations in the intensity of the radiation received at the detector are inversely proportional to the amount of particulate solids in the flow. In one embodiment, the radiation is directed along a path substantially perpendicular to the axis of symmetry of the hydrocyclone and in another embodiment, the radiation is directed along a path at an inclined angle to the axis. Unlike past arrangements in which the nuclear density gauge is used only as an on-off type switch or warning device reacting to the absence or presence of the air column at a particular location within the hydrocyclone, the arrangement of the present invention can be used to monitor density fluctuations in the flow over a wide range. Further, the readings from the nuclear density gauge can be used to adjust the parameters in the operation of the hydrocyclone in order to maintain its operation at peak efficiency.

A valve assembly for controlling the flow of material in a duct such as a pipeline, outlet of a cyclone, nozzle and the like. The assembly is particularly suitable for controlling spiralling flows and includes a plurality of elongated valve members pivotally mounted at a first end to a support. Each valve member has at least two elongated and substantially planar sides extending from the first end to a second end. The two planar sides are joined to form a leading edge. The valve members are supported in an overlapping relationship and a mechanism closes the valve assembly by moving the second ends of the valve members toward each other. As the valve assembly closes, the leading edge of each valve member pivots about an axis and moves in a path along a plane extending radially from the axis of the valve assembly. The valve assembly is biased in the open position by the support means, and, as the valve assembly closes, the leading edge of each valve member in cooperation with the outwardly biasing force from the support means and reacting to the internal pressure drop across the valve forceably scrapes a side of an adjacent valve member in order to form a seal therewith. The leading edges of the valve members converge toward a common point as the valve assembly closes.
