Abstract: A continuous process is disclosed for the acylation or alkylation of aromatic compounds in hydrogen fluoride. The aromatic compound is sufficiently insoluble in hydrogen fluoride that a two phase reaction medium forms. However, surprisingly, the product acylated or alkylated aromatic compound is soluble in hydrogen fluoride. The present invention particularly relates to use of a continuous, multi-stage process for carrying out the acylation or alkylation reaction. In the multi-stage process, the continuous phase can be either the hydrogen-fluoride rich phase or the aromatic compound-rich phase. The movement of the continuous phase relative to the non-continuous (dispersed) phase can be countercurrent or concurrent. The multi-stage process can be operated in a manner such that the aromatic compound feed to the reaction is entirely consumed or such that unreacted aromatic compound is recycled.

Abstract: A woven material is described in which optical fibers are positioned and held in the material in a manner to maximize their optical efficiency. The material consists of fibers extending in both the warp and woof direction, the optical fibers are positioned in channels between the supporting fibers in the warp direction. The material is manufactured using conventional weaving equipment by positioning both the optical fibers and the warp fibers, and then wearing the woof fibers into place without bending the optical fibers. The fibers are thusly woven so that the optical fibers hare zero warp. The woven grid-like mat can be coated with a protective material that either enables it to form a flexible sheet of ribbon or a rigid, hard, grid-like mat which has aligned zero warp optical fibers embedded therein. The material shown can be used to provide sensing, imaging or cammunications. It can be utilized for optical backplanes for optoelectronic systems or a housing for optoelectronic components.

Title: Composite rubber/concrete railroad grade crossing system
Inventor: DAVIS R ANDREW
IPC: E01C9/04
Filed: 1992-03-31
Granted: 1994-09-20
Abstract: A grade crossing system for extending a roadway across a railroad track comprises elongate elastomeric pad units which abut each side of the rails in the track but do not extend across the entire crossing.  The elas-tomeric pad units rest on the ties that carry the rails and have planar top surfaces that are coplanar with the tops of the rails.  The remainder of the crossing is filled with non-elastomeric panels that also rest on the ties and have planar top surfaces that are coplanar with the top surfaces of the rails.  The abutting edges of the pad units and the panels overlap such that the panels hold the pad units down against the ties and urge them against the sidewalls of the rail flanges.  Thus, mechan-ical fasteners are not required to hold the crossing elements in place.

The waistband hinge zone is predisposed to allow the panel zones to bend about a defined axis and is resilient to provide a restoring moment that returns the panel zones to their pre-use configuration, especially when the elasticized waistband has been pretensioned by a closure system (36). The closure system creates and maintains lateral tension through the elasticized waistband thereby allowing the elasticized waistband better expand and contract with the motions of the wearer. The absorbent article additionally preferably comprises a pair of elasticized side panels (30) disposed in the front/rear waist region (58). Alternative features wherein portions of the topsheet (24) and/or backsheet (26) lying in elasticized regions of the article have been prestrained are also described.
