The so-called Stabilized Temperature Platform Furnace ( STPF ) concept, proposed by Walter Slavin, based on research of Boris L ’ vov, makes ET AAS essentially free from interference.

ET was an independent time-variable, proposed ( and its adoption agreed ) in the period 1948 – 52 with the intent of forming a gravitationally uniform time scale as far as was feasible at that time, and depending for its definition on Simon Newcomb's Tables of the Sun ( 1895 ), interpreted in a new way to accommodate certain observed discrepancies.

ET, in turn, can now be seen ( in light of modern results ) as close to the average mean solar time between 1750 and 1890 ( centered on 1820 ), because that was the period during which the observations on which Newcomb's tables were based were performed.

The atomic clocks offered a further secondary realization of ET, on a quasi-real time basis that soon proved to be more useful than the primary ET standard: not only more convenient, but also more precisely uniform than the primary standard itself.

Such secondary realizations were used and described as ' ET ', with an awareness that the time scales based on the atomic clocks were not identical to that defined by the primary ephemeris time standard, but rather, an improvement over it on account of their closer approximation to uniformity.

However, emerging research based on brain autopsies of 50 deceased ET patients ( as of December 2009 ), showed clear degenerative and pathological abnormalities, including " messy " neurofilaments which can impede nerve impulses.

The series ran on ABC Television for an hour each weekday in the 1955 – 1956 and 1956 – 1957 seasons ( from 5: 00 to 6: 00 pm ET ), and only a half-hour weekdays ( 5: 30 to 6: 00 pm ET ) in 1957 – 1958, the final season to feature new programming.

Sometimes the sport is called Quad Hockey, Hóquei em Patins ( PT ), Rolhockey ( NL ), Rollhockey ( DE ), International Style Ball hockey, Rink Hockey ( FR ), Hockey Su Pista ( IT ), Hoquei sobre Patins ( CA ), Hockey sobre Patines ( ES ), Rulleskøjtehockey ( DA ), Rullbandy ( S ), Rulluisuhoki ( ET ) and Hardball hockey ( US ), depending on which region of the world it is played.

The orbiter was lifted up on a sling very similar to the one used at Kennedy Space Center and placed inside the Dynamic Test Stand building, and there mated to the Vertical Mate Ground Vibration Test tank ( VMGVT-ET ), which in turn was attached to a set of inert Solid Rocket Boosters ( SRB ) to form a complete shuttle launch stack, and marked the first time in the program's history that all Space Shuttle elements, an Orbiter, an External Tank ( ET ), and two SRBs, were mated together.

Prior to the closing of the Vandenberg facility, orbiters were transported from the OPF to the VAB on their undercarriages, only to be raised when the orbiter was being lifted for attachment to the SRB / ET stack.

* Ephemeris Time ( ET ) was from 1952 to 1976 an official time scale standard of the International Astronomical Union ; it was a dynamical time scale based on the orbital motion of the Earth around the Sun, from which the ephemeris second was derived as a defined fraction of the tropical year.
