Title: Circuit for switching digital comb filter of tv set and for compensating text
Inventor: SON DAE IK
IPC: H04N5/44
Filed: 1998-11-09
Abstract: PURPOSE: A circuit for switching a digital comb filter of a television set and for compensating text is provided to prevent the deterioration of a screen quality by not passing an unnecessary signal processing route. CONSTITUTION: A circuit solves the problem of a text shift due to the difference of time for processing a teletext process signal while operating a digital comb filter and a switching circuit to decide if the digital comb filter is operated in a TV set. The circuit for switching the digital comb filter and compensating text is composed of a delay compensation circuit(40), a text/image switch(42), and a controller(45). Herein, the delay compensation circuit for compensates the delayed time corresponding to the processing of digital comb filtering for the output of a delay switch(39). And, the text/image switch switches and outputs a deflecting RGB or a text RGB according to a fast blanking signal(FB) of a text processor(41). Then, the controller controls the switching of the delay switch and selects a filtered image signal comb or an input image signal in a deflector(37) according to the on signal of the digital comb filter. Therefore, the circuit prevents the deterioration of a screen quality by displaying the input image to a CPT through a direct deflector without passing through the comb filter when the signal is without SECAM or a color burst.

Abstract: PURPOSE: A structure for a damper is provided to reduce the number of components and the number of assembling processes, to prevent the generation of noise, and to do as a stable role of the damper by simplifying the structure of the damper to absorb the vibration generated in an outer washing tub. CONSTITUTION: When a washing machine is operated, a vibration transferred to an outer washing tub is transferred to a damper cap(114) through a hanging portion of damper. The vibration transferred to the damper cap(114) is buffered by a compressing or a relaxing operation of a damper spring(115) by transferring to the damper spring(115). The remained vibration not to be buffered in the damper spring(115) is transferred to a damper base and a snubber bar(111), and is reduced by transferring to an upper pivot(115) upside the snubber bar(111) and an upper damper hanging portion(103) of an outer case.

Title: Lubricant dewaxing by membrane separation
Inventor: GAULD RONALD MICHAEL
IPC: C10K1/04
Filed: 1997-04-02
Abstract: PURPOSE: Conventional types of dewaxing apparatus are expensive and complex. In many cases, filtration is progressed slowly and bottleneck appears in the process because lubricant/solvent/wax slurry supplies inducted to a filter are viscous and thus the filtration rate is low. In some cases, when solvent is insufficient, the crystallization of wax is bad, and eventually, the lubricant recovery rate may be bad. The use of solvent, to improve the removal of wax from the lubricant, requires recovery of expensive solvent for recycling during separation and dewaxing from dewaxing oil, and thus energy becomes excessive. CONSTITUTION: The invention relates to a dewaxing method of wax-oil supply. Especially, the invention relates to a method of solvent-dewaxing a wax-petroleum mixture and membrane-separating the filtered solvent-oil mixture.
