Abstract: Abstract Wells of subterranean formations containing hydro-carbons are stimulated by the injection of a crosslinked acid polysccharide.  The crosslinked acid polysaccharide is a gel formed from a hydrated polysaccharide sol containing hydrochloric acid and having a pH of less than one to which a water hydrolyzable polyvalent metal salt is added to cause the crosslinking.  The metal salt is zirconium, titanium or hafnium.  The crosslinked acid polymer contains from about 30 to about 120 pounds polysaccharide per 1,000 gallons acid (about 3.6 to about 14.4 kilograms per 1,000 liters acid) and from about 3 to about 28 weight percent hydrochloric acid.     The crosslinked acid polymer retards the chemical reactivity of the hydrochloric acid thereby allowing the acid to deeply penetrate the formation before the activity of the acid is spent,  After its injection, the crosslinked acid polymer breaks down as a result of time and the tem-perature of the reservoir into a less viscous fluid allowing the acid to react with the formation.

Abstract: ABSTRACT OF THE DISCLOSURE    A container for holding a cassette that includes a rectangu-lar casing into which A cassette can be directly inserted and stored and a frame-like bottomless slide which is positioned in the casing and selectively operated for moving the cassette into and out of the casing.  An hourglass-type spring is positioned between the slide and casing to urge the slide to an upwardly extended cassette-exposing position.  A selectively releasable locking mechanism for retaining the slide in a cassette-storing position includes a finger pressure contact indentation formed in the front wall of the slide and double-latch locking projections formed on the front of the slide and casing at opposite sides of the finger pressure contact indentation.  Hublock projections formed on the slide engage the hub-openings of a stored cassette only when the slide is in its cassette-storing position.  The configuration of the slide and casing is such to provide smooth and easy operation of the container and to ensure continued satisfactory and proper operation by not being highly vulnerable to misalignment, warping and dimensional variations in the com-ponent parts.  The casing and slide are formed of a single piece of moldable material with all the subcomponents (except the spring) being integrally molded as a part of the casing or slide.

Abstract: Abstract Longitudinal compressive treatment of web materials by features, novel per se, that perform in concert.  For driving a web longitudinally a stationary low friction member pressed down upon a driven roll provides multiple lines of pressure-concentration against the driven roll.  There lines can provide a positive web drive over varying conditions, can isolate the final point of drive from supply tension, and can establish a relatively tensionless state in the web before final drive and longitudinal compressive treatment.  When webs undergo longitudinal compression while confined under a continuation of the stationary low friction surface, minute steps in the stationary surface define a succession of slightly enlarging treatment cavities that stabilize the treatment under differing conditions.  For retarding the web a flat, fluid-expansible envelope, overlying a stationary retarding surface, acts through a mediating member to regulate downward pressure between retarding surface and web.  A spring sheet member having a decoupling hinge notch formed in its upper surface between feeding and retarding regions can decouple downward pressures in these regions, while providing smooth transition geometry between the regions. Mechanical work energy provided by the longitudinal compressive treatment under regulated treatment conditions provides heat that enables drying of treated paper and, in the case of treated thermoplastic webs, can cause permanent setting of the longitudinal treatment effects as they are produced in the web.  In the case of a web that comprises thermoplastic fibers, permanent setting of a compressively bloomed state of the fibers is achieved by prewarming the web below the softening temperature of its thermoplastic fibers, controlling the web drive speed to exceed a critical level, e.g. about 15 yards per minute, longitudinally compressing the web using a stationary retarding surface that applies a drag force to the web, the longitudinal compression step imparting heat to the fibers through conversion of work energy, and chilling the web following the longitudinal compressive treatment.  Special patterns in the web, and regulated degrees of strechiness are provided by special periodic variations in the retarding surfaces across the running width of the web.
