Surely it is an error by Bachian (" relative to a musician of the Bach family" ). It's not an entry that seemed relevant to me and I was going to let it go , but I was surprised by John's definition and much more that the dictionary boo-hunting bot found that text; so I looked for it . For a change, it's in a commercial brochure (plus espam free. . . ! ) promoting a packaging machine with a programmable control for its "batch processing system" , which in English is known as batch processing. Sip , by an error of the translator is set as 10060;bacht , and bachtiano will then be a consequential interpretation . Guess.
