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 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.
Is a vehicle which is nonautomotive and is designed to be hauled by road.
A transceiver that transmits a signal automatically in response to an appropriate triggering signal.
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.
An expander of the turbine type used to reduce the pressure of a gas flow by leading it through a turbine rotor by which the recovered energy is transferred into rotational energy for either power generation or mechanical drive application.
An assembly of hydraulic hoses which can also include electrical cables or optic fibres, used to control a sub sea structure or remote operated vehicle from a platform or a vessel.
A tank (or a combination of tanks) and connected underground piping having at least 10 percent of their combined volume underground.
Is a sterilizer intended to make use of ultraviolet light.
A pump that utilizes a liquid annulus held by centrifugal force around the inside of a casing by a single rotor-impeller to compress vapour isothermally.
A ventilator is a machine designed to mechanically move breathable air into and out of the lungs, to provide the mechanism of breathing for a patient who is physically unable to breathe, or breathing insufficiently.
A container intended for storage and/or processing of fluids.
A conveyor that is a tubular or flat trough with slides, to which vibrators are attached. The latter impart an upward and forward conveying movement to bulk materials in the trough.
A detecting element that is intended to sense mechanical vibration and in which the oscillating motion is transferred into a voltage or current signal.
A switch intended to give a on/off signal when vibration level have reached a pre-set value.
A signal converter intended to convert one video signal type to another video signal type.
A facility with the capability of receiving video signals and displaying pictures.
A recording instrument that is recording signals originated by a TV camera on a moving magnetic tape for subsequent reproduction or transmission.
A regulator designed to automatically maintain a constant voltage level.
