Rotary table (#20) rotates, along with its constituent parts, the kelly and kelly bushing, the drill string and the attached tools and bit. Shale shaker (#2) separates drill cuttings from the drilling fluid before it is pumped back down the wellbore. Stand (#16) is a section of 2 or 3 joints of drill pipe connected and stood upright in the ...
A detachable chairlift or high-speed chairlift is a type of passenger aerial lift, which, like a fixed-grip chairlift, consists of numerous chairs attached to a constantly moving wire rope (called a haul rope) that is strung between two (or more) terminals over intermediate towers. In contrast to the fixed-grip version, the chairs of a ...
Belt manlift in a parking garage. A belt manlift or manlift is a device for moving passengers between floors of a building. It is a simple belt with steps or platforms and handholds rather than an elevator with cars. Its design is similar to that of a paternoster lift. The belt is a loop that moves in a single direction, so one can go up or ...
A paternoster in Prague Paternoster elevator in The Hague, when it was still in operation. A paternoster (/ ˌ p eɪ t ər ˈ n ɒ s t ər /, / ˌ p ɑː-/, or / ˌ p æ-/) or paternoster lift is a passenger elevator which consists of a chain of open compartments (each usually designed for two people) that move slowly in a loop up and down inside a building without stopping.
IEEE 200-1975 or "Standard Reference Designations for Electrical and Electronics Parts and Equipments" is a standard that was used to define referencing naming systems for collections of electronic equipment. IEEE 200 was ratified in 1975. The IEEE renewed the standard in the 1990s, but withdrew it from active support shortly thereafter.
A diagram of a pumpjack. A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1] It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas.
EAGLE contains a schematic editor, for designing circuit diagrams. Schematics are stored in files with .SCH extension, parts are defined in device libraries with .LBR extension. Parts can be placed on many sheets and connected together through ports. The PCB layout editor stores board files with the extension .BRD.
Diagram 3 shows three rope parts supporting the load W, which means the tension in the rope is W/3. Thus, the mechanical advantage is three-to-one. By adding a pulley to the fixed block of a gun tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a. This is an example of the Luff tackle.
