A point focusing solar collector comprising at least one pair of segments bearing reflecting surfaces. The surfaces are mounted in such a manner that they form a paraboloidal surface. The segments are arranged in a symmetrical manner on both sides of the vertical axis of the collector. The segments are connected to each other. A stand is provided supporting the segments, e.g. that described in U.S. Pat. No. 4,395,582, which is capable of rotating the segments in the vertical and/or horizontal direction for tracing the position of the sun. An absorber is located at the focus of the collector. Each segment comprises two winglike plates being constituted by two side members which are connected to and arranged in a symmetrical manner on both sides of a central rigid shaft having a front and a rear end and which plates are distanced from each other and extend parallel to each other, the side members of one winglike plate being at a location closer to the front end than those of the opposite plate. The plates are connected one plate to another. Holes are bored in the side members of each of the plates along an identical parabolic curve at identical locations thereon. A suitable number of reflecting surfaces are provided and provision for the adjustment of the reflecting surfaces is made.
A mixture containing 3,3-bis(aziodomethyloxetane) and EA3834A for use, when gnited, as a physiologically activating agent against enemy personnel on the battlefield by friendly forces.
