function. Valving around the compressor permits selected directional control over refrigerant flow. The compressor can be selectively disconnected to turn off the heat pump. Air controilably ducted through, over and around the inboard exchanger is circulated into the passenger compartment to cool the occupants, to warm the occupants, and to defrost the windshield.

4690697 LONG RESIDENCE POLLUTION CONTROL SYSTEM Arthur G Schwartz, Richard M Gurries, Jay Johnson Method and apparatus for removing noxious gases, such as, oxides of nitrogen, sulfur or carbon from industrial influent gas streams which utilizes growing plants positioned in long residence contact time apparatus for removing the noxious gases.
SOLAR ENERGY COLLECTOR Ernst Hornung, Dietrich Rex, Stuhr, Federal Republic Of Germany assigned to ERNO Raumfahrttechnik Gmbh A solar energy collector arrangement is comprised of a plurality of parallely arranged striplike mirrors, preferably made of aluminum with a silver layer on a concavely curved surface and solar cells being arranged on the rear convexly curved surface, upon which the mirror next to the first mentioned one concentrates solar radiation. These mirror strips are suspended by means of cable inbetween two bars so as to change the orientation of them vis-a-vis the sun; the bars, in turn, are preferably pivotably connected to a telescopic mast, there being additionally guide cable for gathering the individual mirrors. The entire arrangement can be pulled together by pulling all mirrors in juxtaposed position and pivoting the transverse bars against the telescopic mast.
4690756 APPARATUS FOR MICROAQUACULTUREAND POLLUTION CONTROL Charles Van Ry Apparatus for producing and removing dissolved and particulate matter from natural bodies of water and wastewater in situ for the production of organic biomass such as feedstocks, for the removal of pollutants, nutrients, toxins and other substances, and for other purposes. A gas is introduced through a diffuser into a body of water to form bubbles. The bubbles rise within a lifting tube, gathering dissolved and particulate matter on their surfaces. The bubbles produce a foam at the surface of the body of water, the foam being collected in a reservoir, concentrated and drawn off.

The invention relates to a method of measuring dry substance in the flue gas in liquor recovery units in mills for the manufacture of papermaking pulp in order thereby to render it possible to control the operation of the unit. According to the invention, this is carried out in that the radiation emission caused at the combustion of fuel particles in the hearth of the unit above the fuel supply level is detected optically, and that the signals are used for indication and/or control of the operation of the unit.
The scanning system of a scanning microscope for the imaging of phase structures is adapted to form a scanning pattern which is free from discontinuities. The detector is divided into a number of sub-regions with the direction of the dividing lines of the detector being adapted to the scanning pattern. The scanning pattern is notably meander-shaped and the detector is
divided into four quadrants. The deflection system is digitally controlled and the microscope may be an electron microscope.
