A circulator pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit. They are commonly found circulating water in a hydronic heating or cooling system. Because they only circulate liquid within a closed circuit, they only need to overcome the friction of a piping system (as opposed to lifting a fluid from a point of lower potential energy to a point of higher potential energy).
Elevator traction machine is the power unit of the elevator, and usually located at the elevator machine room. The elevator traction machine used to refer to the collection of components that raise or lower the elevator. These include the drive motor, brake, speed reduction unit, sheaves and encoders. Generally, there are two standard types of driving machines provided for elevators: gearless machine and geared machine.
Caffeine is the world's most popular drug. It is the most commonly consumed psychoactive substance in the world. Caffeine is a substance that is naturally produced in the leaves and seeds of many plants, including coffee beans, guarana, yerba maté, cacao beans, and tea. Caffeine is determined as a drug because it is a central nervous system stimulant. It is used to provide a boost of energy, causing increased alertness. Caffeine gives most people a temporary energy boost and elevates mood, and is also used to stay awake longer.
An antenna is a device that used to transfer guided electromagnetic waves (signals) to radiating waves in an unbounded medium, usually free space, and vice versa (i.e., in either the transmitting or receiving mode of operation). Antenna are frequency-dependent devices. Each antenna is designed for a certain frequency band. Beyond the operating band, the antenna rejects the signals.
Video encoding, also known as video transcoding is basically a process of converting a given video input into a digital format that is compatible with most types of Web players and mobile devices. All the videos people watch via computers, mobile devices, tablets, and set-top boxes have undergone a video encoding process to transform them from the original source format into a format viewable on the said devices.
Dichloroanilines are chemical compounds which consist of an aniline ring substituted with two chlorine atoms. There are six isomers of dichloroaniline. As aniline derivatives, they are named with the amino group in position 1. They are all colorless, although commercial samples can appear colored due to the presence of impurities. Several derivatives are used in the production of dyes and herbicides. 3,4-Dichloroaniline is one of dichloroanilines six isomers.
Aluminium foam is a cellular structure consisting of aluminium with gas-filled pores comprising a large portion of the volume. The pores can be sealed (closed-cell foam) or interconnected (open-cell foam). Foam structures are both durable and lightweight, with a large surface area to volume ratio. The unique mechanical properties of aluminum foam include a high strength to weight ratio and a completely isotropic load response.
