Abstract: The present disclosure is generally directed to a solar distillation system capable of recovering potable water from non-potable water. In certain embodiments, the system includes a substantially air tight solar still having a roof top composed of a solar light-transmitting material. The solar still includes a tube positioned below and running underneath the roof top, the tube having an exit end. Additionally, the solar still includes a heating surface positioned below the roof top and adapted for receiving at least a portion of the non-potable water exiting the tube at the exit end. Non-potable water on the heating surface is solar heated and a portion of the non-potable water evaporates and condenses on the outside of the tube to be collected as potable water.

Abstract: A device which is suitable for treating a fluid comprises an elongated foil formed of a plurality of foil layers arranged in zigzag fashion, wherein a first foil layer is connected to a second foil layer at a first end. The second foil layer is connected to a third foil layer at a second end remote from the first end. Spacers are arranged between said foil layers. The spacer comprises a mesh-like layer, through which fluid can flow in the plane of the mesh-like layer as well as transversely to the plane of the mesh-like layer.

Abstract: A coke oven buckstay moving device and method which can be used to quickly, reliably, and smoothly repair buckstays compared to conventional methods and devices. The coke oven buckstay moving means includes a main car, a subcar, a frame, and securing means. The main car is used when repairing pillered buckstays that support oven walls of the coke oven, and moves on a coke side platform or a machine side platform. The subcar is placed on the main car, and can freely move forward and backward in a direction of a lengthwise direction of the coke oven. The frame is provided in a standing manner on the subcar. The securing members are mounted to the frame and are used to grasp and secure the buckstays. According to the method, a damaged portion of the buckstay is secured to the subcar, cut, and then removed. Reversing the steps, a replacement buckstay is secured to the subcar, moved into position, and welded into place. The subcar is detached, and the oven repaired.

Abstract: A thin film distiller is provided which applies distilland to an evaporative side by the use of wicks which work by capillary action. The evaporated vapor is transferred to the condensate side after being compressed to a higher pressure where it is condensed and removed by similar wicks. The condensing and evaporating surfaces are formed on opposing sides of a bellows-like sheet of heat conducting material. The sheet would preferably be formed into a cylindrical shape with the evaporative stage on the outside and the condensing stage on the inside of the cylinder. Either the wicks or the heat conducting material are moved with respect to the other such that the wicks place a thin film of distilland on the evaporative surface. Removal of condensate is performed in a similar manner by the wicks in the condensate stage.
