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.
A diffuser is "a device for reducing the velocity and increasing the static pressure of a fluid passing through a system”. [1] The fluid's static pressure rise as it passes through a duct is commonly referred to as pressure recovery. In contrast, a nozzle is used to increase the discharge velocity and lower the pressure of a fluid passing ...

GARY, Peacock's docuseries about child star Gary Coleman, covers the highs — and many lows — that he experienced over the years before his tragic death at age 42.. Coleman rose to fame playing ...
The squeeze-film pressure sensor is a type of MEMS resonant pressure sensor that operates by a thin membrane that compresses a thin film of gas at high frequency. Since the compressibility and stiffness of the gas film are pressure dependent, the resonance frequency of the squeeze-film pressure sensor is used as a measure of the gas pressure.
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]
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 ...
