In 1900, Colman invented the Hand Knotter, which could quickly and easily tie knots in string. It was in such high demand that Barber & Colman were able to open their own plant in 1902. Soon they had branches in Boston, Massachusetts and the UK. Colman's Warp Tying Machine, introduced in 1904, was also a great success.
Not all stationary wire-tying balers used two wires. It was not uncommon for the larger bale size – usually 17 in × 22 in (43 cm × 56 cm) – machines to use 'boards' that had three slots for wires and hence tied three wires per bale. Most North American manufacturers produced these machines as either regular models or as size options.
The sequence of events is similar for manual or automatic synchronization. The generator is brought up to approximate synchronous speed by supplying more energy to its shaft - for example, opening the valves on a steam turbine, opening the gates on a hydraulic turbine, or increasing the fuel rack setting on a diesel engine.
With automatic systems, many units in a system can participate in regulation, reducing wear on a single unit's controls and improving overall system efficiency, stability, and economy. Where the grid has tie interconnections to adjacent control areas, automatic generation control helps maintain the power interchanges over the tie lines at the ...

The Avery Company, founded by Robert Hanneman Avery, was an American farm tractor manufacturer famed for its undermounted engine which resembled a railroad engine more than a conventional farm steam engine.
Traditionally, an operator would plant at about 4.5-5.5 mph for optimal performance. However, with the advent of these systems electrical motors match the speed of the tractor and "dead-drop" the seed in the trench using either a belt or brush-belt which cause the forward momentum of the planter to be offset by the rearward momentum of the seed.
