Glass manufacturing is divided into two categories: flat glass for windows and partitions, and blown/molded glass for containers and ornaments. The float glass production line uses a mixture of raw materials and recycled glass that is heated and floated on molten tin to create a flat plate. Blown glass is made by hand or with […]
Tips for production line management include worker positioning, automation, and employee motivation. Worker placement depends on the product being manufactured and supervisors should focus on positive conversations and allow workers to rotate positions. Production numbers should be shown to workers and improvements rewarded. Some of the best production line management tips include positioning workers, using […]
PVC production involves a mixing unit, extruder, mold, and cutting machine. Chemical ingredients are mixed to create a liquid mixture that is pushed through the extruder and molded into various shapes before being cut and stacked for shipping. Polyvinyl chloride (PVC) is a type of plastic common in building and construction materials. The various types […]
Overhead power lines are conductive lines used for energy transmission. They are installed and maintained by utilities and can carry multiple power lines and telecommunication cables. They can be dangerous and require constant inspection and maintenance. Customers should stay at least 10 feet away and report any hazards. An overhead power line is a conductive […]
A supply line is an assembly line in a factory where people and equipment produce parts for the main line. Using feed lines can increase efficiency and production, and a facility can have more than one, especially if it produces complex products. Assembly line manufacturing allows for low-cost mass production. A supply line is an […]
A production line is an organized process of assembling a product using a conveyor belt or other mechanical system. The concept was first used to transform raw products into usable goods and was later used in mass production by Henry Ford. Production lines have streamlined manufacturing, reduced costs, and increased productivity. Automation has further reduced […]
Different types of production line equipment, such as PCB assembly machines, CNC machines, lathes, and extrusion devices, require regular maintenance and calibration to ensure accurate and functioning finished products. Workers with attention to detail examine products, and each machine is managed and adjusted by qualified personnel. Most electronic products have PCBs, and CNC machines create […]
A drill line is a wire rope that helps drill or pump oil and gas from the ground. It is connected to the rig engine and travels through pulleys to increase drilling power. It should not be confused with the drill string, which is a separate mechanism. Drill lines can vary in length and diameter […]
Section lines are used in land surveying to show property lines and narrow down the amount of land to be surveyed. They can also be used to section parcels for township surveys. The standard measurement is one square mile, but can be determined by the surveyor. Section lines make it easier to survey rough terrain […]
“The Old Line” refers to Maryland soldiers who distinguished themselves in the Revolutionary War. The nickname developed into “The Old Line State” and honors the memory of their sacrifices. Maryland’s Old Line was highly disciplined and well-equipped, unlike many other colonies’ soldiers. The nickname’s origin is debated but is displayed on Maryland’s State Quarter. “The […]
Veto power allows a governor or leader to reject parts of a bill before it becomes law. Most US state governors use this power, but Congress ruled it unconstitutional for President Clinton in 1996. Giving POTUS veto power could lead to fewer bills, but advocates argue it would reduce political “handling.” Opponents argue it gives […]
The Maginot Line was a defensive fortification built by France after WWI to protect against invasion. It failed in WWII when Germany outflanked it, leading to France’s downfall. The Line provided a false sense of security and was a military blunder. Today, remnants of the Line can be found, but it is in a state […]
The Mason-Dixon line was initially created by Charles Mason and Jeremiah Dixon to settle land disputes between Maryland and Pennsylvania. It later became a symbolic separation between states that permitted slavery and those that did not during the Civil War, and continues to represent discrimination against black Americans. The Mason-Dixon line has two definitions. One […]
The assembly line was first used in the automotive industry by Ransom Eli Olds and later improved by Ford’s use of the conveyor belt. The moving assembly line increased efficiency, specialization, and required standardization of parts. However, it also caused worker boredom and pressure to perform quickly. The first assembly line was created in the […]
The presidential line of succession ensures that the US always has a leader, even in a crisis. The Vice-President is first in line, followed by the President of the Chamber of Deputies and the President Pro Tempore of the Senate. The line then runs through the Presidential Cabinet. Officials who could succeed to the position […]
The poverty line in the US is the minimum income needed for a satisfactory standard of living, including basic necessities like food, shelter, and medical care. It varies by state, household size, and other factors. In 2010, over 46 million people lived below the poverty line. While many lack access to medical care, most have […]
Line matrix printers are commonly used in offices for high volume printing. They use hammers to create dots on a page, similar to a dot matrix printer. The wide shuttle holds multiple hammers that fire to create lines of points, and the printer can produce black and white graphics. A line matrix printer is a […]
Powerline networking uses electrical outlets to connect computers without new cables. Intellon’s PowerPacket is the standard, offering faster speeds, built-in encryption, and resistance to energy consumption and aged wiring. OFDM technology transmits data on unused frequencies, increasing speed. The older Passport technology is slower and requires manual encryption. PowerPacket kits cost around $59 and are […]
Line service technicians provide ground support to aircraft, including fueling, directing planes, handling baggage, and monitoring safety. No special education is required, but a driver’s license is helpful. Safety is a priority, and job requirements may include physical fitness and a high school diploma. A line service technician provides ground support to aircraft as they […]
The line of best fit is a mathematical tool used to describe the relationship between two properties in a scatterplot. It is determined by finding the line with the smallest mean difference between the line and the closest point. The slope and intercept of the line are important in describing the relationship. The least squares […]
