Tackles: The running, rigging or roping used in working the sails with
their pulleys. Also an arrangement consisting of a rope and pulley block used to
obtain a purchase in shifting a cannon.
Tail Rods: Extensions to the piston rods which protruded through the
front of the cylinders so fitted. Tried from time to time during the 1890s and
early 1900s, fitting tail rods was said either to save wear on cylinders or to
cause it, depending on who was speaking. They were not taken up universally and
many locos which had them when built were later modified to remove them.
Tangible Personal Property: Anything other than real estate or money,
including furniture, cars, jewelry and china.
Tank Locomotive: A steam locomotive which has its coal and water
storage on the same frames as the engine. The design first appeared in 1835 in
Ireland. The water tanks are the most obvious feature as they are mounted on
either side of the boiler partially obscuring it. There are different types of
tank engines, side tanks are the most common. Well tank locomotives, where the
tank is hung under the frames, were less common.
Technology: This general class of missions includes all missions
designed as technical tests of satellite or ground based systems. Examples
include tests of new satellite components, investigations of launch vehicle
performance, calibration of ground based systems (such as radar), and
demonstration of new sensor technologies.
Third Party Litigation: When a lawsuit is brought against a defendant
and that defendant wants to add another party to the suit, the original
defendant may file a “third party complaint” which results in a third party
litigation or lawsuit.
Tort: A civil wrong; a wrongful injury to a person’s property. There
are three types of torts: intentional, negligence and strict liability.
Transport: Transport missions include all spacecraft that are used to
ferry people or materials from the Earth to orbit without performing significant
research. Missions in this class include space station re-supply vehicles and
Shuttle missions whose primary purpose is to carry satellites into orbit for
deployment.
Tug: A small vessel designed to tow or push large ships or barges.
Tugs have powerful diesel engines and are essential to docks and ports to
maneuver large ships into their berths. Pusher tugs are also used to push
enormous trains of barges on the rivers and inland waterways of the U.S.
Oceangoing salvage tugs provide assistance to ships in distress and engage in
such work as towing drilling rigs and oil production platforms.
