Abstract: Cathodic protection of an existing concrete structure, including a steel member at least partly buried, such as steel rebar, in the concrete structure, is provided by embedding anodes into a fresh concrete layer applied over an excavated patch and/or as a covering overlay. The anodes are embedded at spaced positions or as an array in the layer and connected to the rebar. A  corrosion inhibitor is added into the fresh concrete at least at the interface and more preferably in admixture with the fresh concrete which acts to reduce the flow of ionic current to the steel or between the anode member and the steel in the fresh covering material without significantly increasing the resistivity of the fresh covering material and without inhibiting the ionic current between the anode member and the fresh covering material. In this way the current to the steel in the existing concrete is maximized to maximize the cathodic protection to the existing steel which is the primary target.

Title: Self centering skate holder
Inventor: SUNNEN AUGUST
IPC: B24B41/06
Filed: 2004-12-16
Granted: 2008-08-12
Abstract: A self-centering skate holder for clamping a skate blade from above and below which maintains the blade at a pre-determined height and parallelism. A handle is connected with a cable which is taut and extends around the circumference of the upstanding vertical member. The movements of the cable activate cam levers which rotate cams that move a pair of jaws towards or away from each other. The simultaneous movements of the cams ensure that the jaws move in unison and through a similar distance allowing a skate blade of any thickness to be clamped along the desired centerline. In an alternative mechanism, a tie bar extends between the jaws and is operated by a cam to induce equal and opposite movement of the jaws.

Abstract: Techniques for managing XML data in an SQL compliant DBMS include receiving an SQL statement. The SQL statement includes a particular operator that operates on a first instance of XML type that represents a first set of XML elements. During execution of the SQL statement, the particular operator is evaluated by generating an ordered collection of instances of XML type. Each different instance in the ordered collection is based on a different XML element from the first set; and there is an instance in the ordered collection for every XML element from either the first set or from the first set and its descendents. When descendents are included, each entry in the ordered collection indicates a level in the XML tree. In another aspect, an aggregate operator in the SQL statement operates on a collection of instances, with associated levels, to generate a single instance of XML type.
