A liner or cover system is provided, which can at times have at least a portion of its area exposed to wind and/or ground fluid action and consequent damage, and which is held in position against dislodgement and therefore against damage by said action by an anchoring means or structure. The system is held anchored from under it at a plurality of loci by said anchoring means or structure which exerts at each said loci a force at least equal to the maximum force of wind and/or ground fluid expected to act at any time at said loci independently from any force acting at any time at any other of said loci of said liner or covering. Also, there is provided a method for constructing said system which includes among its steps bringing together at least two sections or laps to be incorporated to form said liner or cover, joining the laps to form at least a portion of said liner or cover or system, and anchoring said liner or cover from below it at a plurality of loci to form at least a portion of said liner or covering. The loci at which anchoring is effected are distributed at least across the exposed area of the liner or covering, preferably in a grid-like pattern. Several embodiments of the system are included within the description, drawings and the claims. In use, the system can contain, retain or fend off fluid or liquid from contact as with the ground or other substance to be covered as in an impoundment, channel and/or in the prevention of evaporation of a liquid, e.g., water, or collection of a fluid, e.g., geothermal steam, or e.g., storage of agricultural products.

Covering or liner system and method for constructing the same

A process to obtain liquid and gaseous hydrocarbon products from low grade carbonaceous deposits such as lignite, by retorting a first portion to produce a hydrocarbon oil, and reacting a second portion with the oil, thus producing increased fuel oils and gases.

Conversion of lignite to higher quality fuels

An extrudate element is inserted into a base material so that a portion of the extrudate enters into or traverses the base material. The inserted extrudate element, the constituent of the base material, or both are composed of an expandable extrudate containing an expansion agent. The expansion agent is activated during or after insertion of the extrudate element to cause enlargement of the expandable extrudate and/or the substrate or base. This enlargement fixes the extrudate element into the base material by tightening the inserted element against the base material to wedge it in place, as by causing portions of the inserted element to enter interstices of the base material, or by causing the inserted element to expand on both sides of the insertion opening to a diameter greater than that of the insertion opening. The insertion and subsequent fixing into a base material of a plurality of elements produces a pile surfaced article. In one embodiment a plurality of elements composed of a foamable material containing a suitable foaming agent is extruded directly through a base material and foamed, thereby locking the foamed elements into the backing to form a pile surface of foamed extrudate.
