  • Patent number: 4470268
    Abstract: A heat exchanger container (2) having a round or square cross-section is divided longitudinally into a boiler compartment (4) and an absorber compartment (5) by a hygroscopic partition wall (1) provided with surfaces (11) on the boiler side, respectively (12) on the absorber side. At both ends of the partition wall (1) are provided sealing elements (10) which insulate the partition wall from the container (2). Cooling vanes (3) increase the active outer surface of the container (2). A condenser (6) for liquifying the refrigerant is located after the container (2) in the flow direction. Then comes a choke member (8) intended to choke control the refrigerant. Finally there is provided an evaporator (7) of which the outlet is connected to the absorber compartment (5) of the container (2). Pipes connect the container (2) on one hand to the condenser (6) and on the other hand to the evaporator (7). This sorption refrigerating apparatus may be set in operation continuously.

  • Patent number: 4295821
    Abstract: A burner apparatus for burning liquid fuels is equipped with a swirl atomizer nozzle (4), a flame holder (22) that is connected behind the nozzle mouth, and a combustion air delivery duct (8), in which the nozzle (4) is arranged coaxially. A thermally decoupled duct-like heat conductor (10) functions as a fuel vaporizer in the operation of the apparatus. In its main portion, which starts a small distance downstream from the nozzle, the heat conductor has an inside diameter such that droplets in the spray cone from the nozzle tend to impact evenly over the whole area of its inner surface. The heat conductor (10) is of silica nitride. It comprises at least partially a capillary inner layer.
