Barrel inspection

Barrel inspection To ensure proper performance, different parts of the barrel can be checked to meet tolerance requirements (usually setup by the manufacturer) and determine if any wear has occurred such as inside diameter, straightness and concentricity, and surface condition. 

It cannot be emphasized too strongly that dirt and correct lubrication are incompatible. The lubricant manufacturer has a comprehensive system of classification, filtration and inspection of packages, which ensures that all oils and greases leaving his plant are free from liquid and solid contaminants. It is in his own interests that the user should take the same care to ensure that the lubricant enters his machinery in as clean a condition as that in the bulk tank or barrel. The entry of abrasive dust, water and other undesirable matter into bearings and oilways may result if lubricants are handled carelessly. 

Inspection of the barrel and screw for wear can provide information on the root cause for the wear. For example, if wear occurs at an axial location on only one side of the barrei and on all sides (angular direction) of the screw, then the likely root cause is that the barrel is out of alignment at that axial location. Conversely, if the barrei is worn on all sides and the screw is worn on only one side at the same axial location, then the root cause is likely a local bend in the screw. 

Chemical Analysis. It is suggested that a set procedure be established for running specific analyses according to a specific timetable. For example, a visual and taste inspection of all wines every two weeks (two months for wines in barrels), malic and lactic acid analyses at weekly intervals during the malo-lactic secondary fermentation, and S02 and color analyses of white wines at least every two weeks until the wine is bottled. Basic analyses to monitor are V.A., S02, alcohol, pH, and T.A. 

To conclude, the visual inspection of samples during compression testing is important if barreling is observed, ways should be sought to eliminate the friction effects prior to collecting data. 

For the purpose of visually inspecting the interior of a vessel, tank or barrel which is classified as zone 0, light generated by a zone 1 luminaire, which is located outside the vessel in zone 1, is brought into zone 0 via a fibre optics bundle. In the luminaire, the light is focused on the aperture of the fibre optics bundle by means of a condensor lens (Figs 11.1 and 11.2). 

Engineering members of the serine protease family which structurally consist of two homologous, stacked /1-barrels, Hopfner and coworkers designed a hybrid protease by fusing the N-terminal /1-barrel from trypsin to the C-terminal /1-barrel of factor Xa [74], The location of the fusion point in the linker region between the two /1-barrels was chosen following close inspection of the X-ray structures of trypsin and factor Xa. The resulting hybrid was shown to be fully functional as it hydrolyzed a broader but distinct spectrum of peptide substrates in comparison to the parental enzymes. 

The proof marks employed by the inspectors in the U. S. Qovemment armories, and placed on all arms inspected by them, even if made in private armories, are V for viewed, and P for proved, together with the initial letters of the inspector s name, and are found stamped on each barrel. On many guns of the old model arms will be found, in addition to these marks, the head of an eagle. This is the mark that indicated that the barrels were made at the armory at Harper s Ferry, when those works were in operation.

Cracks or voids in the expl fill of an artillery shell are hazardous because they have the potential of causing a premature expln before the shell leaves the gim barrel. Shells are therefore inspected using X-ray film imaging techniques which are both relatively slow and expensive.
