Abstract: A self-positioning light fixture with a stabilizing base comprises a self-righting member in the shape of a spherical segment and a separate lamp supporting member with connecting means to join the two together and to separate each from the other. When separated, a filling neck or spout on the top wall of the self-righting member is exposed through which fluid ballast material such as sand may be poured into the cavity of the self-righting member. The filling neck has external threads to engage the internal threads of a recess opening to the bottom wall of the lamp supporting member when received therein to thereby couple the two members together. Additional fastening screws are provided to more securely connect the self-righting member to the lamp supporting member. A shock absorbing mechanism is provided comprising mounting springs to secure the lamp bulb socket member to the lamp supporting member and thereby protect it from shocks transmitted to the lamp fixture.

Abstract: An illumination system includes an artificial radiant source that emits energy in the visible and infrared regions of the spectrum. A radiation splitter splits the majority of the visible energy from the majority of the infrared energy to form an illumination beam and a heating beam.

A solar collector may direct a solar beam on the radiation splitter to supplement the artificial source beam. A supporting portion may support a lighting fixture. An artificial illumination source is placed at a position that is unsupported by the supporting portion, and a light conductor provides an optical path for radiation produced by the source to the fixture.

Abstract: A plurality of lean NOx catalysts are installed in passages of a dual passage portion of an exhaust conduit of an internal combustion engine. A space velocity changing means including a valve is provided at a connecting portion of the passages so that the amount of exhaust gas flowing through the lean NOx catalysts is altered periodically. When a space velocity of exhaust gas at the lean NOx catalyst changes from a low velocity to a high velocity, an NOx purification rate of the lean NOx catalyst increases momentarily. By repeatedly generating the NOx purification rate increased conditions, the NOx purification rate of the NOx purification apparatus including the plurality of lean NOx catalysts is greatly increased.
