The automatic lubrication system is connected to a control system via switchs. The control system may involve human input or may be computerised (computer numerical control or CNC). [2] [3] There are advantages of using an automatic lubrication system over a manual system. For example, there are savings in the costs of human resources. The ...
Eli Terry was using interchangeable parts using a milling machine as early as 1800. Ward Francillon, a horologist, concluded in a study that Terry had already accomplished interchangeable parts as early as 1800. The study examined several of Terry's clocks produced between 1800–1807. The parts were labelled and interchanged as needed.
The pumps of the DV type lubricator are operated by a sliding shaft assembly, unlike the Silverton or Wakefield lubricators which are operated by a rotating camshaft. [6] The FSA type lubricator differs by each pump having two separate pistons to control the pumping & distribution of oil. The pistons are driven by cams on the driving shaft.
By 1800, the firm Boulton & Watt had constructed 496 engines, with 164 driving reciprocating pumps, 24 serving blast furnaces, and 308 powering mill machinery; most of the engines generated from 5 to 10 hp. An estimate of the total power that could be produced by all these engines was about 11,200 hp.
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."

The RFA 300 pumps at flow rates less than 1 milliliter per minute through 1 millimeter ID glass mixing coils. Throughput on the RFA can approach 360 samples per hour, but averages closer to 90 samples per hour on most environmental tests. In 1986, Technicon (Bran+Luebbe) introduced its own microflow TRAACS-800 system. [11]
