Is a solid state device that converts heat flux (temperature differences) directly into electrical energy

A pilot switch whose function is controlled by variations of temperature and whose contacts make or break automatically a load circuit when the temperature of the ambient space in which its sensing element placed or the temperature of the surface on which it is fixed reaches a predetermined value.

A physical object that is a pressure-tight receptacle adapted to receive a temperature sensing element, provided with external threads or other means for pressure-tight attachment to a vessel or pipe.

A physical object that includes a water jet or propeller used on vessels intended to provide a means to move the vessel sideways for maintaining the vessel's position without anchors.

A semiconductor device that is a three-terminal semiconductor rectifier made up of four layers, p-n-p-n, so that when the fourth is positive with respect to the first, a voltage pulse applied to the third layer initiates a flow of current through the device which continues as long as it is greater than some minimum value.

A timepiece that measures a time interval and signals its end; a time-switch.

A device that is a mechanical implement for working upon something, as by cutting, striking, rubbing or other processes, in any manual art or industry; usually, one held in and operated by the hand (or fixed in position, as in a lath), but also including certain simple machines, as the lathe; sometimes extended to simple instruments of other kinds.

A top drive is a mechanical device on a drilling rig that provides clockwise torque to the drill string to facilitate the process of drilling a borehole.

A fluid coupling intended to allow a smooth start of a driven equipment and then keeping a nearly constant speed.

A tank which is supposed to be transported.

A machine designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery

Is a vehicle which is nonautomotive and is designed to be hauled by road.

A transformer that, by electromagnetic induction, transforms a system of alternating voltage and current into another system of voltage and current usually of different values and at the same frequency for the purpose of transmitting electrical power.

A physical object that is an element that receives a process variable signal from a sensor and converts it into an output signal.

A transceiver that transmits a signal automatically in response to an appropriate triggering signal.

A tree cap is a barrier to keep the subsea environment clean in case of any leaks above the annulus or production swab valves. It includes a mechanism to indicate the metal seals have been set within the seal bore of subsea tree.

A narrow excavation of considerable length cut into the ground.

A pilot switch intended to create a switch action at a pre-set value.

Trip & throttle valves provide flow control and emergency shut-off operation for steam turbines in a single valve assembly

A vehicle that is intended for transporting heavy loads.

An motor vehicle that is long, low and open intended for carrying goods by road.

A well string hanger that is used for production tubing. The tubing hanger incorporates a sealing system to ensure that the tubing conduit and annulus are hydraulically isolated.

A physical object that is intended to rotate within a fluid and to transform energy within a fluid into mechanical power.

A velocity flow meter that uses a multi bladed rotor to measure fluid flow rate in units of volumetric flow through a closed conduit.

A transmitter specially designed to convert the signal in a turbine meter into a standardized output signal.
