Sketchy, a portrait-drawing delta robot [1] A delta robot is a type of parallel robot [2] that consists of three arms connected to universal joints at the base.

In 1798 he received another patent, this time for the hot rolling of plates and sheets using a tandem mill. The tandem mill's main advantage was increased production: only a single pass was required, saving time; and greater tensions were possible between the stands, increasing the reduction in the stands for the same roll force.
High-leg delta (also known as wild-leg, stinger leg, bastard leg, high-leg, orange-leg, red-leg, dog-leg delta) is a type of electrical service connection for three-phase electric power installations. It is used when both single and three-phase power is desired to be supplied from a three phase transformer (or transformer bank).
The delta winding allows third-harmonic currents to circulate within the transformer, and prevents third-harmonic currents from flowing in the supply line. [2] Delta-wye transformers introduce a 30, 150, 210, or 330 degree phase shift. [3] Thus they cannot be paralleled with wye-wye (or delta-delta) transformers.
The new Terminal A handles flights by Air Canada, American Airlines, Delta Air Lines, JetBlue (except for international arrivals from non-precleared flights which are handled at Terminal B), and a minority of United flights not in Terminal C.

In the UK this type of tap normally has a wheel-shaped handle rather than a crutch or capstan handle. Cone valves or ball valves are another alternative. These are commonly found as the service shut-off valves in more ...
