Abstract: While a user is viewing in a first display area a portion of an electronic document intended to be printed to produce a printed product, presenting to the user in a second display area a representation of the physical outline of the printed product and an indicator that indicates to the user the size and location of the electronic document portion relative to the printed product. When the user positions a cursor in the second display area, a second indicator image, visually distinctive from the first indicator image, is displayed. The user can position the second indicator at a desired location relative to the representation and request that the portion of the electronic document at that second indicator location be displayed in the first display area.

Abstract: Systems, methods and computer program products are disclosed for providing an edit location indicator. The indicator is displayed to a user while the user is performing editing actions to create an electronic document design that is intended to undergo subsequent printing and processing to produce a printed product. The indicator has a number of individually modifiable sections, each indicator section corresponding to a physical section of the type of product being designed. When the user performs an electronic edit action, the section of the product corresponding to the location of the edit action is identified and the corresponding section of the indicator is modified to present to the user a visual indication of the section of the product affected by the edit action.

Abstract: A method using two local clipboards in conjunction with the system clipboard to perform cut-and-paste and copy-and-paste operations during the creation and editing of markup language documents. A user editing a document has the option of cutting or copying an entire textbox or selected text from within a textbox. If an entire textbox is copied, two local clipboards are used in combination with the system clipboard to store related information in multiple locations. Upon receipt of a paste command from the user, if a text insertion cursor is present, the text to be pasted is inserted into an existing textbox. If no text insertion cursor is present, a new textbox is created and the text is inserted in the new textbox. The attributes of the text in a newly created textbox depend on how and from what source the text was cut or copied.

Abstract: A system and method for automatically generating composite images from component images selected by a system user and incorporating the composite images into an image of a custom product. The user can select component images in any sequence and can delete, add, replace or change component images and colors during the design process. The library of component images is organized into categories and subcategories for presentation to the user.

Abstract: A bridge structure includes a light-weight, corrosion-resistant, readily installed bridge deck formed of modular deck panels spliced to each other on site. The deck panels are preferably shop-fabricated by longitudinal welding of adjacently placed multi-void elongate structural elements. Longitudinally adjacent elongate elements are spliced by providing internally disposed shear elements prior to longitudinal welding of adjacent spliced elongate elements, with the end joints between spliced elongate elements being arrayed in a staggered manner. A safety rail system is mounted to run alongside and above outer edges of the finished bridge deck mounted to a system of support girders.

Abstract: Novel difunctionalized cyclobutabenzene monomers of the general formula: ##STR1## wherein Z can be hydrogens or a cyclobutane ring; and X and Y are carboxyl, amino, alcohol, isocyanate, acid halide, or bis-acyl halide groups. Exemplary difunctional bitricyclodecatriene monomers are ?2,2'-bidicyclo?2.4.0!octa-1,3,5-triene!-5,5'-dicarboxylic acid (BXTA) and ?2,2'-bitricyclo?6.2.0.0!deca-1,3,(6),7-triene!-7,7'-dicarboxylic acid (QXTA). The difunctionalized bitricyclodecatriene monomers can form part of a polymer backbone chain in which the multiple butane ring functionalities can be easily opened to produce strong, three-dimensional covalent bond crosslinking between polymer chains. The crosslinking can be induced simply by heating the polymer to a temperature in excess of 250.degree. C.

Abstract: Novel difucntionalized cyclobutabenzene monomers of the general formula: ##STR1## wherein Z can be hydrogens or a cyclobutane ring; and X and Y are carboxyl, amino, alcohol, isocyanate, acid halide, or bis-acyl fluoride groups. In a particularly preferred embodiment, the cyclobutabenzene derivative is 1,2-dihydrocyclobutabenzene-3,6-carboxylic acid. The difunctionalized cyclobutabenzene monomer can form part of a polymer backbone chain, but has an additional functionality, the butane ring, which can be easily opened to produce strong, covalent bond crosslinking between polymer chains. The crosslinking can be induced simply by heating the polymer to a temperature in excess of 300.degree. C.

Abstract: There is provided an improved method of cleansing a filter bed utilizing a backwash pump (12) having an inlet line (14) and an outlet line (16). The improved method and system includes two cycle operations. Initially, the filter bed is backwashed to remove contaminants from the filter bed with the backwash pump (12) drawing liquid from an effluent channel (32) through a first diverter valve (18). The fluid flows through a second diverter valve (20) and a first throttling control valve (36) for insert into a backwash shoe (38). In the purging cycle, fluid may be recirculated from the backwash pump (12) through the backwash shoe (38) and then back to the backwash pump (12) with a portion of the fluid being diverted through a second diverter valve (20') into an egress line (42).

Abstract: An improved method of cleansing a filter bed is herein provided utilizing a backwash pump (12) having an inlet line (14) and an outlet line (16). The improved method and system includes two cycle operations. Initially, the filter bed is backwashed to remove contaminants from the filter bed with the backwash pump (12) drawing liquid from an effluent channel (26). A portion of the liquid passing on backwash pump outlet line (26) is passed through a bypass adjustment valve (34) for egress on an outlet line (38) for recirculation to the effluent channel (26). The second stage of the cleansing operation is through a purging cycle where the filter bed is purged subsequent to the backwashing operation for removal of further contaminants from the filter bed.
