| jonovid:
a look at the technology before the age of micro-controllers that is still in use today. from the many types of telegraph, to the control system used by the Otis Elevator. I was researching railway technology of the 1900s. signals and other railway technology. for a railway locomotive project were I needed to know what electrical engineering was used at the time. research had links to George Westinghouse and the railway air brake systems. among other things, ships engine order telegraphs. I did came across this video about 1900s elevator technology long before the age of micro-controllers. clever people made do with what ever they had at the time. and some of this telegraph type electrical engineering work was still in use when this video was made. go to 2:30 on the 6:34 video 1958 gearless traction Otis Elevator machine room tour. |
