  • Publication number: 20070193286
    Abstract: The invention relates to a method for controlling a running time of an absorption refrigerating system of an absorption refrigerator, which absorption refrigerator comprises two differently tempered refrigerator compartments. The method comprises the steps of: monitoring the temperature in a first compartment; activating the refrigerating system when the temperature sensed in the first compartment exceeds a predetermined value; de-activating the refrigerating system when a cut-out temperature is reached; monitoring the time period during which the absorption refrigerating system is turned off; and supplying heat to the first refrigerator compartment, when the time period exceeds a predetermined time period. The invention also relates to a microcontroller, computer program product and to an absorption refrigerator comprising means for performing the inventive method.

  • Patent number: 7063982
    Abstract: A process for evaporating a liquid feed and reacting said feed in the presence of catalyst to make product within a reactor having both an evaporation zone and a reaction zone comprises the steps of providing packing in the evaporation zone, providing catalyst in the reaction zone, introducing the liquid feed to the evaporation zone through an injector having an orifice, where the orifice and the packing define a gap that is sufficiently small to interfere with the formation of a liquid drop at the orifice, vaporizing the liquid feed within the evaporation zone to form a vapor, flowing the vapor to the reaction zone and contacting, at reaction conditions, the vapor with a catalyst to form product.

  • Publication number: 20050229404
    Abstract: A combination knife including a common blade member that carries two different blade elements having cutting edges, each blade element located on a respective side of a pivot joint carried in a knife handle and around which the common blade member can be rotated. One blade element includes a conventional knife-acting cutting edge, while the other blade element includes a stomach-opening cutting edge situated on the upper edge of the blade element when in its use position. A stop is provided for preventing rotation of the common blade member relative to the handle after rotation of the common blade member in a direction such that one of the two cutting edges has been brought to its use position. The cutting edge of the knife-acting blade element and that of the stomach-opening blade element are situated along the same edge of the common blade member.
