Abstract
DE 102006016314 B3 UPAB: 20071026 NOVELTY - The jet spray tool for the production of a jet of carbon dioxide snow for dry cleaning of tube cavity, comprises a shaft (11), carbon dioxide jet nozzle (13), an inlet line for carbon dioxide, which is attached to the nozzle and which runs along the shaft. The nozzle is arranged at or in an end of the shaft in such a manner that it is tiltable around at least an axis, which does not coincide with the jet direction of nozzle and which extends through the nozzle. The shaft exhibits a round and/or an oval and/or a quadrangular and/or polygonal cross section and a joint. DETAILED DESCRIPTION - The jet spray tool for the production of a jet of carbon dioxide snow for dry cleaning of tube cavity, comprises a shaft (11), carbon dioxide jet nozzle (13), an inlet line for carbon dioxide, which is attached to the nozzle and which runs along the shaft. The nozzle is arranged at or in an end of the shaft in such a manner that it is tiltable around at least an axis, which does not coincide with the jet direction of nozzle and which extends through the nozzle. The shaft exhibits a round and/or an oval and/or a quadrangular and/or polygonal cross section and a joint. The inlet line runs inside the shaft. A part or the whole length of the inlet line for CO2 is a capillary. The inlet line is arranged spirally around a straight line defined by a swivel axis of the nozzle. The nozzle is freely tiltable at a level in defined angular region. The nozzle is tiltable over a push pull cable, which runs inside and/or along the shaft, and/or is tiltable over a drive, which is arranged at the end of the shaft exhibiting the nozzle and/or which is directly connected with the nozzle. The push pull cable is controllable by means of the drive- or supply unit (18) and that the nozzle is controllable by means of a drive. The material discharged by the shaft can be sucked off by means of at least a withdrawal duct. The shaft is rotatable around its axis and also exhibits a compressed gas supply line. Over the inlet line, supercritical CO2 and/or liquid CO2 and/or gaseous CO2 and/or CO2 -pellets are led to the nozzle. The feeding of the liquid CO2 and/or gaseous CO2 and/or CO2 -pellets takes place under 50-400 bar, related to the inlet line. A defined leakage exists between the region of the compressed gas supply line and the suck-off region and/or the withdrawal duct. The leakages are aligned along the surfaces, which are movable relative to one another by movement of the shaft and/or the nozzle, and/or along the sealings. The nozzle is formed as a conical extension of the CO2 -feed line, is accommodated in a nozzle needle, which is surrounded by a nozzle head, and is surrounded by a reinforcement nozzle connected with the compressed gas supply line for production of a stabilized jet. The shaft exhibits or consists of high-grade steel, other metals, plastics and/or ceramics. A supersonic jet is generatable with the reinforcement nozzle, which is Laval nozzle, which concentrically encloses the CO2 -nozzle and which is formed as an intermediate space between the nozzle needle and the nozzle head. An INDEPENDENT CLAIM is included for procedure for dry cleaning of tube cavity. USE - For dry cleaning of tube cavity (claimed). ADVANTAGE - Ensures high cleaning efficiency and cleans both particle and film-like contaminants in micrometer range. By a freely tiltable nozzle, a flexible adaptation of the cleaning cycle in the internal contour of the tube cavity is possible, so that an entire surface, dead zone-free cleaning of the tube can be achieved.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
