Boart Longyear wireline core retrieval system, an innovation that revolutionized the diamond drilling industry by increasing productivity on the worksite and making tripping core from the bottom of the hole safer for the drilling assistant. Later named the Q Wireline System, the new core retrieval method introduced a level of productivity never before seen in the exploration drilling industry. In 1964 Longyear sold 25 percent of its family-owned stock to FACTS, a Luxembourg-based holding company owned jointly by Boart International and Christensen Diamond Products Company. Three years later FACTS exercised its option to purchase another 25 percent of Longyear's family stock. The
Waste heat which allow power stations to maintain the low side of the temperature difference essential for conversion of heat differences to other forms of energy. Discarded or "Waste" heat that is lost to the environment may instead be used to advantage. Industrial processes, such as oil refining, steel making or glass making are major sources of waste heat. Although small in terms of power, the disposal of waste heat from microchips and other electronic components, represents a significant engineering challenge. This necessitates the use of fans, heatsinks, etc. to dispose of the heat. For example, data centers use electronic components that
