Patent DE-19602154-A1 (DE)
Title: Drinking water treatment process alternates reverse flow between two filters
IPC: C02F1/00
Filed: 1996-01-22
Abstract: Drinking water filtration process simultaneously back-flushes the filter. The water is surrendered to a first filtration vessel (2) and filtration material (3), and flows from the bottom to the top. The water from the upper zone (19) of the first vessel (2) is then transferred to second filter vessel (4) and with filter material (4). The water flows through the second filter from top to bottom and is then discharged. The flow pattern is reversed at regular or irregular intervals ranging from 0.5-10 hr. During filtration, a portion of the water is continually tapped off from one of the upper zones (19, 21) or the transfer pipes and measured in terms of time or volume. This water is discharged as waste. Water flowing upwards loosens the filter material (3, 5).

Title: Pointing method of window frame, icon of window interface in computer
Inventor: HO HENG-CHUN
IPC: G06F3/033
Filed: 1997-03-14
Abstract: The method involves pointing a window frame from among multiple rectangular shaped window frames (62a-62i) of a window interface (62), using a mouse. Six window frames are displayed over a monitor screen (45). The other three frames are in an embedded state. The upper end of a specific frame is highlighted to signify the pointed status and the other windows are displayed in a normal manner. The control button of the mouse is actuated to generate a pointing signal. A frame control module receives the pointing signal and detects the window frame position data contained in the frame position file. When a window frame is detected, the frame control module designates and displays the detected window frame as a pointed window frame over the monitor screen and also changes the display of the last pointed frame. If the detected frame is not displayed or is partialled displayed, the frame control module scrolls the contents of the screen, such that the detected window frame is completely displayed over the screen. Each of the window frames is opened or closed by a bi-directional button of the mouse. A window software maintains a background file for keeping information about the closed window frames. When an open window is closed, the information about the closed frame is recorded in the background file.
