Abstract: Trace data is received for a first execution of a first query on first tables having first data values. Second data values are generated for second tables from the trace data and without accessing the first data values. The second data values are configured to reproduce, by a second execution of a second query, the evaluation states from the first execution. Evaluation states from the first execution are reproduced without accessing the first data values by performing the second execution of the second query on the second data values. The first execution evaluates only a first subset of the first data values and the generating the second data values from the trace data generates second data values corresponding to the first subset. The second execution only evaluates ones of the second data values that correspond to data values of the first subset.

Abstract: Trace data is received that was captured for an execution of a query on first tables when execution trouble occurs during an execution of the query on the first tables. Trace data includes counts of evaluation states caused by the execution and includes identifications of portions of the query that reference variables of the first tables and that correspond with the evaluation states. Second tables are generated from the evaluation state counts and the identifications of the trace data without accessing data values of the first tables, so that the first tables are kept private. Evaluation states are reproduced from the execution of the query on the first tables by executing the query on the second tables without accessing the data values of the first tables.

Abstract: Trace data is received that was captured for a execution of a first query on first input data. The trace data associates clauses of the first query with respective evaluation states that arise during the execution. Second input data is generated from the trace data without accessing the first input data. An execution of a second query is performed on the second input data, wherein performing the execution of the second query on the second input data reproduces evaluation states from the execution of the first query on the first input data.

Abstract: An improved method for draping curtains which allows one person to form a decorative window treatment known as a bishop tail without requiring any specialized skills or training. The method described hereinafter allows a fabric scarf to be draped from a rod of conventional configuration in a decorative manner about a window opening. The method uses hook and loop type fasteners means to secure the fabric scarf to the rod and thereby prevent the fabric scarf from sagging at the top. Curtain rings are placed over the ends of the depending fabric scarf and then installed on the rod near its ends to allow a portion of the fabric scarf to form a decorative downwardly curved arc of fabric. The newly formed arc is then "dressed" or folded into pleats in accordance with the teaching of U.S. Pat. No. 5,146,972 to William L. Tacchella. A hook closure ring is then installed through the previously hemmed edges of the fabric scarf and hung by a cord from the wall bracket to form the bishop tail.

Abstract: A process and apparatus are disclosed for treatment of crystalline, particulate phthalocyanine pigments, and particularly for green shade phthalocyanine blue pigments. To effect development of the pigment tinctorial strength by reduction of the pigment particle size, the pigment particles are repeatedly impacted against relatively fixed impact plates by entrainment in moving air streams. Repeated impacting of the particulate pigment provides significant reduction in its particle size and significant development of the tinctorial strength of the pigment. It is presently preferred that the impacting steps be carried out in conjunction with subsequent viscous grinding of the partially developed pigment. This combination of treatment steps has been found to provide a resultant product of significantly enhanced tinctorial strength, while at the same time affording significant savings in materials, process time, and energy usage.

Abstract: An improved membrane-type end closure member for composite containers or the like is disclosed, characterized in that the end closure member is deformed to define an annular deformation of generally V-shaped or flat bottom transverse cross-section, which deformation extends partially within the end of the container when the end closure member is bonded to the open upper end of the container body. The annular deformation, which is arranged between the annular flange portion that is bonded to the end extremity of the container and a central circular disk portion of the end closure member, serves to reinforce the relatively thin flexible membrane member and flexes or "domes" in response to variations in internal pressure of the container to maintain the container in a closed condition.
