[…] Another point noticed was the widespread use of small-package solid-state logic (such as "and," "or," "not") and instrumentation (timers, amplifiers, etc.) units. There would seem to be a good case here for the various manufacturers to standardise practical details such as mounting, connections and power supplies so that a Siemens "Simatic (de)," say, is directly interchangeable with an Ateliers des Constructions Electronique de Charleroi "Logacec," a Telefunken "Logistat," or a Mullard "Norbit" or "Combi-element."

The centrifugal governor, which was invented by Christian Huygens in the seventeenth century, was used to adjust the gap between millstones. Another centrifugal governor was used by a Mr. Bunce of England in 1784 as part of a model steam crane. The centrifugal governor was adopted by James Watt for use on a steam engine in 1788 after Watt’s partner Boulton saw one at a flour mill Boulton & Watt were building.
Another major shift in automation is the increased demand for flexibility and convertibility in manufacturing processes. Manufacturers are increasingly demanding the ability to easily switch from manufacturing Product A to manufacturing Product B without having to completely rebuild the production lines. Flexibility and distributed processes have led to the introduction of Automated Guided Vehicles with Natural Features Navigation.
I used Firebug to find the ID of the search button (magnifying glass) on the page, then used .getElementById again to grab it, and the .Click method to click it. Alternatively, we could have submitted the search box form like this instead objIE.document.getElementById("search_form_homepage").Submit. Actually, there’s a simpler method still that would allow us to skip the previous 3 steps altogether. Can you see it? Hint: take a look at the url we ended up with… https://duckduckgo.com/?q=auto+parts+in+Houston+TX. Got it? If you still don’t see it, and you don’t think you’ll be able to sleep tonight, email me 🙂
