  Explorer 4 - Wikipedia, the free encyclopedia
Explorer 4 was a US satellite launched on July 26, 1958.
The Department of Defense's Advanced Research Projects Agency had initially planned two satellites for the purposes of studying the Van Allen radiation belts and the effects of nuclear explosions upon these belts (and the Earth's magnetosphere in general), however Explorer IV was the only such satellite launched.
Explorer 4 was a cylindrically shaped satellite instrumented to make the first detailed measurements of charged particles (protons and electrons) trapped in the terrestrial radiation belts.

 Explorer Information
Explorer-I, officially known as Satellite 1958 Alpha, was the first United States earth satellite and was sent aloft as part of the United States program for the International Geophysical Year 1957-1958.
The satellite instrumentation of Explorer-I was designed and built by Dr. James Van Allen of the State University of Iowa.
Explorer-I was placed in an orbit with a perigee of 224 miles and an apogee of 1,575 miles having a period of 114.9 minutes.

 JAVA - Satellite   (Site not responding. Last check: 2007-10-22)
The data from the single Geiger-Mueller tube on Explorer I (as the payload was called) yielded the discovery of the radiation belt of the earth -- a huge region of space populated by energetic charged particles (principally electrons and protons), trapped within the external geomagnetic field.
The attempted launch of Explorer II was a vehicular failure, but the launch of Explorer III on 26 March 1958, with an augmented version of the Iowa instrument, was successful.
Analysis of our Explorer IV data on the natural radiation belt as well as on the artificial radiation belts from the Argus bursts propelled the entire subject to a new level of understanding and broad scientific interest.

 TIME Magazine Archive Article -- Big Shot -- Aug. 04, 1958
Explorer IV soared northeast along the New England coast, into a looping orbit which will span more of the earth's surface—including most of Russia.
Explorer IV's extra beef—it is seven pounds heavier than Explorer III—went into instruments custom-built to examine this ionized belt, which may reach all the way to the sun and could well thwart mortal designs on outer space.
Within minutes of launch, Explorer IV was wheeling with the other moons, 170 miles up at the lowest, 1,400 miles up at the highest, sending back vital intelligence on this cosmic barrier.

 DOJ/Antitrust
Indeed, Microsoft's own witness explained that Microsoft designed Internet Explorer 3 to be "uninstalled" in response to corporate customer demand for a version of Windows 95 that did not permit employees to "access the Internet and spend all their time surfing the web" (JA 1641, 1685-87).
The conclusion is the same with respect to Internet Explorer 3 because Microsoft could have complied, and eventually did comply, with the preliminary injunction simply by declining to enforce its licensing agreements to prevent OEMs from "uninstalling" that product (JA 1423-29, 1780).
Rather, Section IV(E)'s two subsections broadly prohibit what in antitrust parlance are certain "positive" and "negative" tying arrangements and categorically bar such arrangements for the very reasons the Sherman Act may condemn them.

 Convair B-58 Hustler -- Chapter 20   (Site not responding. Last check: 2007-10-22)
The target of the King Lofus IV launch was to be the Explorer IV satellite.
However, shortly before the launch it was found that Explorer IV's orbital parameters were inaccurately known, and the target was changed to the newly-launched Explorer V. The launch took place on September 22, 1959, with the launching B-58 flying at an altitude of 37,500 feet and a speed of Mach 2.
It is not known what happened to the missile, and how close it got to Explorer V. Even though the Lockheed/Convair ALBM program was modestly successful, very little long-term interest in the project was generated by the Department of Defense, and no further work was carried out.

Eine Ausnahme von diesem Grundsatz besteht jedoch dann, wenn innerhalb eines Gesamtzeichens ein Zeichenbestandteil derart bestimmend ist, daß er den Gesamteindruck des Zeichens prägt (BGH GRUR 1996, 406, 407-"Juwel").
Innerhalb des Gesamtzeichens "FTP-Explorer" ist jedoch der Bestandteil "Explorer" das eindeutig prägende Zeichen, da bereits der Bestandteil,,FTP" entgegen der Bezeichnung,,Explorer" nicht aussprechbar ist und schon deshalb geringere Kennzeichnungskraft aufweist.
