The machine tool division was sold to fellow Rockford company Bourn & Koch, who provides parts, service, and support for their machines to this day. Barber–Colman henceforth focused on cutting tools and process controls. The remaining divisions were eventually sold off. The Barber–Colman trademark is held by Eurotherm Controls, Inc.
Duct leakage test in the US. A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
Barber realized that the mixing and placing operations needed to be separated, and the mixing section became the line of Barber Greene asphalt plants and the placing section became the Barber Greene paver line. The early pavers used screw conveyors to distribute the mix in front of a screed that tamped the mix. This process meant that the ...

Originally called the Barber-Colman Impressor, the Barcol impressor was developed by Walter Colman as a hand-held, portable means of assessing the hardness of a material during World War II. [2]
A tenter using a Barber-Colman knotter. A Barber-Colman knotter is a piece of textile machinery used in a weaving shed. When all the warp carried on the weavers beam has been used, a new beam replaces it. Each end has to pass through the eyes on the existing heddles, and through the existing reed.

The Coleman Lantern is a line of pressure lamps first introduced by the Coleman Company in 1914. This led to a series of lamps that were originally made to burn kerosene or gasoline. Current models use kerosene, gasoline, Coleman fuel or propane and use one or two mantles to produce an intense white light.
The strength and direction of magnetic fields and electric currents can be measured using a "magnetoresistive barber-pole sensor" (also called a "hermetic proximity sensor"), and its performance can be depicted using a mathematical formula. [33] Such a sensor interleaves a series of permanent magnet strips with a series of magnetoresistive strips.
