The oil droplets then pass through drillings to the bearings and thereby lubricate the moving parts. [3] Provided that the bearing is a ball bearing or a roller bearing, splash lubrication would usually be sufficient; however, plain bearings typically need a pressure feed to maintain the oil film, loss of which leads to overheating and seizure.
The 1950s also marked the beginning of the product that Braun is known for today: the electric shaver. Braun's first electric shaver, known as the S 50, was designed in 1938, but World War II delayed its introduction until 1951. [8] It featured an oscillating cutter block with a very thin, yet very stable steel-foil mounted above it.
Parts cleaning is a step in various industrial processes, either as preparation for surface finishing or to safeguard delicate components. One such process, electroplating , is particularly sensitive to part cleanliness, as even thin layers of oil can hinder coating adhesion .
The goal of modern engine break-ins is the settling of piston rings into an engine's cylinder wall. A cylinder wall is not perfectly smooth but has a deliberate slight roughness to help oil adhesion. As the engine is powered up, the piston rings between the pistons and cylinder wall will begin to seal against the wall's small ridges. [1]
The origins of the "Remington" name date back to the formation of E. Remington and Sons, a firearms maker founded in 1816. E. Remington & Sons made occasional forays into products other than firearms, such as sewing machines and farm implements—but its most significant side venture was when inventor Christopher Sholes persuaded the firearms company to help him develop the typewriter with the ...
A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.
Generally, circular or cylindrical blades (rotary-type shaver) move in a circular motion and oscillating blades (foil-type shaver) move left and right. Hitachi has produced foil-type shavers with a rotary blade that operates similarly to the blade assembly of a reel-type lawn mower. The first electric razor was built by Jacob Schick in 1928. [29]
Vaginal lubrication fluid is a plasma transudate which diffuses across the vaginal wall. Composition varies with length of arousal. [1]During arousal, vaginal lubrication, also sometimes called "arousal fluid", is produced.
