Its construction and principle of operation is simple. It consists of a titanium filament through which a high current (typically around 40 A) is passed periodically. This current causes the filament to reach the sublimation temperature of titanium, and hence the surrounding chamber walls become coated with a thin film of clean titanium.
In vacuum applications, a cold trap is a device that condenses all vapors except the permanent gases (hydrogen, oxygen, and nitrogen) into a liquid or solid. [2] [needs update] The most common objective is to prevent vapors being evacuated from an experiment from entering a vacuum pump where they would condense
In the field of oil regeneration and re-refining, vacuum pumps create a low vacuum for oil dehydration and a high vacuum for oil purification. [44] A vacuum may be used to power, or provide assistance to mechanical devices. In hybrid and diesel engine motor vehicles, a pump fitted on the engine (usually on the camshaft) is used to produce a vacuum.
There have been incidents of babies suffocating while in carriers, particularly "bag sling" styles, and Consumer Reports urged a recall of all slings of this type in 2009. [11] [12] [13] Consumer Reports recommends soft infant carriers (mei tai or soft structured carriers) and backpack baby carriers over these styles. [14]

When using a tube-shaped bag, the ends of the bag are sealed and the air is drawn out of the bag through a nipple using a vacuum pump. Consequently, uniform pressure approaching one atmosphere is applied to the surfaces of the object inside the bag, holding parts together while the adhesive cures. The whole bag may be put in a temperature ...
Vacuum pumps: A vacuum pump sucks air or air/steam mixtures from the chamber. Superatmospheric cycles: Achieved with a vacuum pump. It starts with a vacuum followed by a steam pulse followed by a vacuum followed by a steam pulse. The number of pulses depends on the particular autoclave and cycle chosen. Subatmospheric cycles:
Vacuum truck. A vacuum truck, vacuum tanker, vactor truck, vactor, vac-con truck, vac-con is a tank truck that has a pump and a tank. The pump is designed to pneumatically suck liquids, sludges, slurries, or the like from a location (often underground) into the tank of the truck. The objective is to enable transport of the liquid material via ...
