Abstract: The process of making synthetic silica glass occurs in a combustion chamber of a muffle furnace. It includes producing a gas flow containing a fuel, an oxidizer, and a silicon compound that is converted by flame hydrolysis and/or by chemical oxidation to SiO2 particles, and depositing them on a target to form a roll-shaped silica glass body. The combustion chamber is provided with a gas inlet and a gas outlet arranged at opposite ends of the combustion chamber, which widens from the inlet to the outlet. The gas flow is produced by a central nozzle for the silicon compound, a first concentric ring-shaped nozzle for the oxidizer, and a second concentric ring-shaped nozzle for the fuel. The process is characterized by a ratio of areas of ring gaps of the ring-shaped nozzles of from 1:4 to 1:6.1. The apparatus for the process is also part of the invention.

Abstract: An air bearing has a rotor having a circularly curved radial rotor bearing surface along its circumferential direction. The air bearing also has a stator having at least one radial stator bearing surface partially enclosing the rotor in the circumferential direction. The radial stator bearing surface is curved according to a profile following the circumferential direction of the rotor and is fashioned to generate an air gap between it and the radial rotor bearing surface so that, upon operation, the rotor is borne, supported by an air current in the air gap. The profile shapes the air gap such that, at a starting temperature that deviates from an operating temperature, the air gap has a smaller thickness (measured in the radial direction) in a second region of the radial stator bearing surface in comparison to a first region of the radial stator bearing surface along the circumferential direction.

Abstract: Methods and apparatuses enable generation of an executed workload electronic record. The executed workload record indicates data related to one or more performance metrics by which performance of a work task is evaluated. One such performance metric is an expected time for completion of the task. Performance of the task can be monitored to determine an actual completion time for the task to compare against an expected completion time. The executed workload record can be used for evaluation of workers. Executed workload records provide centralized, aggregatable information for evaluation purposes.
