Abstract: A flexible grout composition is used to cement a conduit within a bore hole to prevent fluid loss, for sealing and grouting well casings, plugging abandoned wells, and waterproofing earthen structures. The flexible grout composition includes a water-swell­able clay, such as bentonite; a particulate filler, such as calcium bentonite; a water soluble silicate; a source of multivalent metal cations; and a gelling agent for the water-swellable clay, particularly an inorganic gelling agent such as magnesium oxide or sodium carbonate (soda ash). The grout composition is mixed with water to form a slurry and the slurry is pumped into its intended location, for example, within the annulus defined between an outer surface of a conduit or casing disposed within a bore hole, and the surrounding earthen formation formed, for example, by drilling.

Abstract: In an electrophotographic copier, adjustments are made to synchronize copy sheet gating optics start of scan, and document conveyor registration. The adjustment to the copy sheet gating is effected by making a copy with the optics assembly inactivated, determining the length of undeveloped area adjacent to the leading or trailing edge of the copy, and adjusting the start of scan as a function of the determined length. The start of scan of the optics assembly is effected by positioning a test master document with dark portions adjacent to its leading and trailing edges, making a copy of the test master document, determining the length of undeveloped area adjacent to the leading or trailing edge of the copy, and adjusting the start of scan as a function of the determined length. The adjustment of the document conveyor registration is effected by feeding the test master document to the document glass, making a copy of the test master document, determining the length of undeveloped area adjacent to the leading or trailing edge of the copy, and adjusting the document conveyor as a function of the determined length. The determining steps may be done by visual inspection or by an optical sensor. The adjusting may be done manually, either electronically or mechancially. In the alternative, the adjusting may be done automatically in response to the optical sensor.

Abstract: The present invention relates to the preparation of substantially pure diastereoisomers of derivatives of tetrahydrofolate and the use of such diastereoisomers. More particularly the present invention provides a process for the preparation of a desired substantially pure (6R or 6S) diastereoisomer of a derivative of tetrahydrofolic acid or salt or ester. The process comprises the steps of: attaching a chiral auxiliary group at either N-5 or N-10 of a mixture of 6R and 6S diastereoisomers of tetrahydro­folic acid, separating the new diastereoisomers, recovering the desired new diastereoisomer (6R or 6S) corresponding to the desired (6R or 6S) diastereoisomer, and converting the substantially pure new diastereoisomer recovered into the corresponding diastereoisomer.

Abstract: A method and apparatus for forming a package comprising plural fibers, particularly hollow fiber membranes, and the product package thus formed. Plural fibers are laterally spatially segregated into at least two groupings each of which consists of multiple fibers and are maintained in their laterally spaced groupings during processing. Winding of the groupings upon a spool is accomplished such that the laterally spaced segregation of the groupings is preserved during traversal of the groupings of fibers from one end of the spool to the other end and each fiber of the grouping for each successive layer wound upon the spool is caused to be wound in substantial parallel alignment with respect to those fibers of an immediately preceding layer. During traversal, the fiber groupings are permitted by means of guide structures to be laterally slidably displaced axially paral­lel    the winding axis of the spool. In such a manner, fiber-to-fiber interaction is minimized whereby upon unwinding from the package, each fiber is readily separable from the other fibers of its respective grouping without damage thereto.
