Storage drive dependent track removal in a cache for storage
In one embodiment, storage drive dependent track removal processing logic performs destage tasks for tracks cached in a cache as a function of whether the storage drive is classified as a fast class or as slow class of storage drives, for example. In one embodiment, a destage task configured for a slow class storage drive, transfers an entry for a track selected for destaging from a main cache list to a wait cache list to await destaging to the slow class drive. A destage task configured for a fast class storage drive allows the cache list entry for the selected track to remain on the main cache list while the selected track is being destaged to the fast class storage drive, thereby bypassing the transfer of the entry to a wait cache list. Other features and aspects may be realized, depending upon the particular application. |

Measuring documentation completeness in multiple languages
Source code is analyzed to identify components. The components are each assigned a complexity score. Documentation for the source code is identified, related to the components, and given a score based on the quantity of the documentation for the component and the complexity score for the component. To determine semantic meaning of the documentation, vector embeddings for the documentation languages may be generated and aligned. Alignment causes the different machine learning models to generate similar vectors for semantically similar words in the different languages. Since the vectors of the words of the other languages are similar to the vectors of the words in a primary language with similar meanings, the vector representation of the documentation in the other languages will match the vector representation of the source code when the documentation is substantially on the same topic. |

Clean-out cap locator
The clean-out cap locator forms a cap that encloses a clean-out plug. The clean-out cap locator comprises a threaded cap, a control circuit, a remote control, and a personal data device. The control circuit determines the GPS coordinates of the control circuit. The control circuit transmits the GPS coordinates of the control circuit to the personal data device. The control circuit generates an audible alarm indicating the location of the clean-out cap locator. The control circuit senses the flow of fluid around near the clean-out cap locator. The control circuit transmits an alarm to the personal data device when the control circuit senses a back-up in the clean-out plug. The control circuit generates an audible alarm when the control circuit detects a back-up in the clean-out plug. The remote control sends a signal to the control circuit that causes the control circuit to generate an audible alarm. |

Fluid seal having multiple diameters
A seal to prevent fluid transfer using double diameters to provide a tighter seal is disclosed. The double diameter seal has a body with a first diameter containing an upper contact area and a second diameter forming a lower contact point. A notch extends into the body between the upper contact area and the lower contact point for a predetermined distance to form a transition point. In use, the first diameter is dimensioned to place a portion of the length of the upper contact area in sliding engagement adjacent to a length of the first surface. The second diameter dimensioned to place the lower contact point contacting an angled second surface of a valve. |

Oil lubrication mechanism for front bearing of water-cooled motor and motor driving assembly
The present disclosure discloses an oil-lubrication mechanism for a fore bearing of a water-cooled electric motor and an electric-motor driving assembly, which solves the problems of conventional grease lubrication of the fore bearing of water-cooled electric motors such as serious bearing heat generation and bearing failure and low life caused by easy outflowing of the grease. The oil-lubrication mechanism includes a gear-splashing oil-storage structure provided in a gearbox or a reduction gearbox, and a bearing-baffle oil-storage structure provided at a front end of the water-cooled electric motor; and a gear in the gearbox or the reduction gearbox in operation throws a lubricating oil into the gear-splashing oil-storage structure, and the lubricating oil is delivered via the oil conduit into the bearing-baffle oil-storage structure, thereby lubricating the fore bearing of the water-cooled electric motor, and subsequently the lubricating oil flows back into the gearbox or the reduction gearbox via the oil return tube. In the present disclosure, the lubricating oil that splashes inside the gearbox or the reduction gearbox is introduced into the fore bearing of the water-cooled electric motor, which enables the fore bearing of the water-cooled electric motor to be lubricated by the oil, thereby reducing the heat generation of the fore bearing of the water-cooled electric motor, and improving the life of the fore bearing and the reliability of the electric motor. |
