Abstract: A binder for releasably retaining loose-leaves. The binder has a front cover that lies flatly beneath its back cover when the binder is open 360 degrees. The rings of the binder can rotate around an edge of the flatly-folded cover to enable loose-leaves to lie flat above and below the cover. The binder also has a skeleton with a minimal cross-section spine which may be partially or completely embedded in a cover and rotates in relation to parallel front and back covers when the binder is open 360 degrees. The front cover, middle cover and back cover are connected in a way so that they do not interfere with the rotation of the rings. Mechanisms to open and close the rings of the skeleton to allow addition or removal of loose-leafs, and ring shapes to optimize or stabilize the capacity of the binder during operation are also disclosed.

Abstract: In a pocket of flexible sheet material comprising: a) a plurality of holes placed adjacent at least one edge of said pocket and adapted for releasable engagement with means capable of penetrating said holes, the main novel feature is b) that for each hole, a slit extends from said edge into the hole, each slit being rectilinear and opening tangentially into the hole concerned at the part of said hole lying most distant from said edge, the region adjacent said edge and in which said holes are formed being reinforced. With this arrangement, the pocket can be inserted into and removed from a loose-leaf ring binder without opening the rings by carrying out a simple procedure, at the same time ensuring that the pocket will not be pulled out inadvertingly, such as by weight of heavy documents in the pocket. It is also possible to use the pocket in a ring binder in which the rings are not adapted to be opened.

Abstract: The invention provides a locking device for locking two matching lens cell halves of a lens cell. In particular, the invention resides in clips which are located at the joint where the two cell halves mate. The clips, which are molded as part of each cell half, are each comprised of a male member which is inserted into a female member. The male member includes a flexible tab which is deflected when inserted into the female member. After insertion, it is maintained in a deformed state, that is the tab is maintained by the female member so that it is bent from its original position. As a result, a bending moment is induced and maintained in the tab and that moment pushes the tab against an outer wall of the female member. Consequently, forces are established which lock the male member in place. Additionally, the wall of the female member exerts a force on the tab and that force, which is inwardly directed, serves to lock together the two halves and ensures retention of the lens units within the lens cell.

Abstract: The article includes a first piece (7) provided with two flexible lugs adopting, in the absence of any force, a position of rest in which they can, over a certain length, be inserted without effort into an opening (6) in a support (1), and a second piece (30) having a fixing foot (32) adapted to cooperate with the first piece so that the fixing foot can be inserted through the first piece (7) as far as a configuration of locking on the support in which the fixing foot (32) keeps the flexible lugs on the first piece (7) separated and in which the first and second pieces (7, 30) are snapped into each other.

The anchor lock is also able to raise the guide post by upper lockpins in axial slots in the guide post lock passing through upper, radial bores in the guide post. The lower lockpins are pressed inwardly by means of the lower beveled edge of the funnel.

Abstract: A process for treating earth materials such as rock heaps to prevent acid rock drainage therefrom is disclosed. First, the oxygen concentration in the gas-phase of the rock heap is decreased, that is, displaced and/or depleted. This first step may be accomplished physically, chemically or biologically. Then, the gas-phase oxygen concentration in the heap is maintained at a low level.

Alternatively, the density of the gas-phase of the rock heap may be increased, and maintained at an elevated level indefinitely. The process is applicable to waste heaps from mining and industrial operations such as power generation and minerals processing, and to rubble collections in open and closed mines.
