  • Publication number: 20150034129
    Abstract: A dewaxing device and a method of dewaxing using the dewaxing device are shown. The dewaxing device includes a dewaxing system including a rinsing device and a storage device, and a recycling system connected with the storage device. The storage device includes a first solvent trough and a second solvent trough of which each is connected with the rinsing device and is equipped with a heating equipment. When the first solvent trough is connected with the rinsing device, the second solvent trough is disconnected with the rinsing device; when the second solvent trough is connected with the rinsing device, the first solvent trough is disconnected with the rinsing device. So, the dewaxing device can provide two dewaxing processes and effectively reduce recycling frequency because the recycling process is done after soluble wax quantity of bromopropane solvent reaches the maximum value 16%. The production cost is accordingly reduced.

    Abstract: The present invention relates to a navigation method. The navigation method provides a navigation display while a GPS terminal device is moving along a road with a traffic marking marked thereon and when GPS information is not available. The navigation method captures a plurality of images comprising the road image with traffic markings and calculates a time of the GPS terminal device passing by the end points of the traffic marking. Then, the moving velocity is computed by using the time as divisor and the unit line as dividend. The navigation method utilizes a GPS terminal device comprising an image capture unit and a timer. The image capture unit captures images and the timer calculates the time.
