![]() ![]() Discharging below about 1.150 or less than about 30 percent capacity is unhealthy for the cells. A lead acid battery uses sulfuric acid and water as an electrolyte, a fully charged battery will have a specific gravity of 1.256, a deeply discharged battery will be somewhere at or below around 1.100. It is small but it really gets the message across.īack to the batteries, most would speak 1250 rather than 1 decimal 250 when talking to another crewman. If we are ever allowed to travel again, plan a visit to the he Royal Navy Submarine Museum at Gosport. Sea Wolves - The extraordinary story of Britain’s WW2 submarines It deals a bit more with the personalities than the technical side but is a great read. If you are interested in British submarine history in WW2, this book is outstanding. Here in all its analog glory is a portion of the main switchboard on one of these boats: To test for leaks they just charged the interior with compressed air, and if the pressure didn’t drop they were good to go! They didn’t even have Christmas-tree indicator panels. Part of the attraction it is that the systems on these early boats are, for the most part, easy to understand. Sometimes the skippers seem more like fighter pilots than boat skippers. Part of it is the amazing battles they got into. Each cell in a submarine battery produces from 1.06 volts when fully discharged, to 2.75 volts at the optimum output, so connecting the 126 cells in each battery in series gives a usable output of from about 210 to 350 volts… submarine battery systems:Īmerican fleet submarines had two batteries, each composed of 126 cells. Other than this I haven’t found much on British WW1 sub battery systems. So if it was a 120-volt system, why did the voltmeters register the volts as 12-ish? Just because? Or was it a function of the way the cells were wired/grouped? The same book says the cells were 2.5 volts. Underfoot as in the after compartment, was the great hundred-and-twenty volt battery which fed the hungry motors, 'We’ll carry on on the series switch till five o’clock, we’ll be in 12 fathoms then, and sit on the bottom till dark. How’s the battery?’ ’ 11.85 and 11.81, sir,’ came the voice of the L.T.O., bending over the pilot-cell. How’s the battery?’ ’ 12.10 and 12.06, sir,’ answered Seagrave. My question is, why would the voltmeters read in the 12-11 volts range, when the batteries operated at 120-volts? I found a book that has the following passage: _method_response ((string) message.response_body.flatten().A question for any fans of WW1-vintage British E-class subs (operated from 1912 to 1922): Open_subtitles.vala:261.92-261.92: error: Argument 3: Cannot pass value to reference or output parameter Open_subtitles.vala:218.92-218.92: error: Argument 3: Cannot pass value to reference or output parameter ![]() Open_subtitles.vala:168.92-168.92: error: Argument 3: Cannot pass value to reference or output parameter Open_subtitles.vala:136.92-136.92: error: Argument 3: Cannot pass value to reference or output parameter _method_response ((string) message.response_body.flatten().data, -1, v) Open_subtitles.vala:92.92-92.92: error: Argument 3: Cannot pass value to reference or output parameter Let user select criterion to select subtitles: best subtitle rating, preferred subtitle format, preferred language (if multiple filters are used), preffered server (if multiple servers are used).Ĭreate a shared library for subtitle searching and downloading (long term)Ĭomments and suggestions are very appreciated. Example: submarine -l eng Season01/*.avi | xargs tar -czf Season01.gz Support more subtitle services (primary goal) The source code is hosted on GitHub ( ) and there is a package in AUR ( ).ĭownloading subtitles for multiple movies at onceĭownloading subtitles from multiple online services (only one is available for now: )įiltering subtitles by any number of languagesĪutomatically renaming subtitles to movie filenamesĪutomatically retrieving subtitles that are best rated The application is written entirely in vala and has little runtime dependencies. The subtitles are properly renamed depending on movie filename and subtitle format so they are automatically used by movie players. Submarine is a subtitle search and download command-line application for fetching subtitles based on movie file hashes. So I decided to write my own subtitle fetcher. I've tried different software to download appropriate subtitles for movies but didn't like any of them. ![]()
