Abstract: Embodiments of the invention provide methods, apparatus, and articles of manufacture for editing network parts present a computer-aided design (CAD) model of a utility network using grips. The network parts may represent elements present in a real-world utility network. Among others, the grips may include a part size grip and a structure rotation grip. When a user selects a part size grip, a graphical user interface may display hash marks to indicate a variety of sizes of the network part provided by a network parts catalog. Dragging the resize grip may cause it to jump from one hash mark to the next, allowing the user to easily select one of the available part sizes. A structure rotation grip may be used to rotate a network part representing a utility network structure about an asymmetric axis.

Abstract: One embodiment of the invention provides a method for generating a curved pipe object in a computer-aided design drawing where the geometry of a curved pipe object is generally represented as a segment of a helix. A user selects a curved pipe creation method and a set of geometric attributes from which the helix parameters may be determined. From the helix parameters, a display representation of the curved pipe object may then be generated and displayed in the CAD drawing.

Abstract: A method, system, and article of manufacture provide the ability to redline or mark up geographic information on a personal digital assistant (PDA). An application on the PDA is configured to obtain map data from a server and display the map data on a screen of the PDA. Markup data is obtained from a user through a stylus that is used to markup the map displayed on the PDA. A file comprised of the markup data is created and then uploaded from the PDA to the server. Accordingly, the markup data comprises a markup layer that is stored locally on the PDA and uploaded (synchronized) with the server automatically when a list of a set of maps is updated.

Abstract: Water soluable, aqueous salt solution dispersible polymers and aqueous salt solutions containing dispersed polymers are produced by polymerization of ethylenically unsaturated soluble monomers in an aqueous salt solution in the presence of at least one carbohydrate. The polymers and aqueous salt solutions containing the dispersed polymers are useful for paper making, water clarification and emulsion breaking.

Abstract: Oil-in-water (reverse) and water-in-oil (obverse) emulsions in crude oil production and processing systems are resolved by addition of a treatment solution comprising a copolymer of acryloxyethyltrimethyl ammonium chloride (AETAC) and acrylamide. The mole percent of AETAC is above about 20% and the molecular weight (grams per mole) of the copolymer is above about 2 million. The treatment solution is effective in matrix which include high percentages of oil and at high temperatures.

Abstract: A process for preparing a water-soluble polymer dispersion is herein provided which is characterized by polymerizing from about 10 to 50 mole percent of a monomer having a formula (II); from about 1 to 50 mole percent of N-alkylacrylamide, N, N-dialkylacrylamide or mixtures thereof; having a formula (III) from about 1 to 70 mole percent acrylamide; and optionally up to about 4 mole percent of a monomer having a formula (I) having a benzyl functionality. The polymerization is carried out in the presence of an aqueous solution of a polyvalent anionic salt which contains (1) a water soluble cationic polymer which is insoluble in the aqueous salt solution and (2) a water soluble cationic polymer which is soluble in the aqueous salt solution.

Abstract: Processes for making coated cubic boron nitride abrasive particles for use in grinding wheels are provided having thick multilayer metal coatings which improve retention of the particles within abrasive tools. The metal coatings comprise a primary metal layer chemically bonded to the surface of the abrasive particles and a secondary layer which forms the bulk of the coating. Coated CBN abrasive particles, abrasive tools made therefrom and processes for their production are also provided.

Abstract: Multi-layer coated diamond abrasive particles which exhibit good retention in abrasive tools and are simpler to manufacture are provided, wherein the coating comprises a single homogenous, carbide forming metal primary layer, preferably of chromium, and at least one non-carbide forming secondary layer, preferably of nickel, iron, cobalt, or alloys thereof. The primary layer is preferably applied so as to chemically bond to the surface of the diamond abrasive particles without sintering following deposition by using chemical vapor deposition or packed salt bath deposition.
