Title: Insulating coating for refractories, coating process and the associated articles
Inventor: RANCOULE GILBERT
IPC: C04B41/50
Filed: 1988-06-25
Granted: 1996-08-22
Abstract: The invention relates to an insulating coating for thermal protection of refractory bodies made of ceramic materials such as submerged casting nozzles used for the continuous casting of steel and of other metals. The coating is a suspension preferably comprising, by weight: 30 to 85% of vitreous silica particles, 0 to 10% of ceramic fibres, 0 to 7% of binder, 0 to 40% of frit and 15 to 30% of water; after application of an antioxidant glaze, the refractory body (room temperature or preheated) is immersed in a deflocculated composition for a controlled period of 5 to 60 seconds to obtain a coating from 1 to 6 mm in thickness; the coated body is then dried and ready for use. The coated nozzles can be employed for cold-starting a continuous casting operation without requiring preheating.

Abstract: The cash register can choose displaying an  amount  of  sales without printing a  receipt  through  the  check  mode.  The  cash register comprises a printer for priting the  receipt,  a  display for expressing a sales status, a keyboard for inputing  data,  ROM for built-in program, and RAM  for  storing  data.  If  a  special number key and a cash/sales function key  is  sequentially  pushed via the keyboard after the check mode is  soelected,  the  printer prints a report expressing the total cash- sales status.  If  only the cash/ sales function  key  is  pressed   the  total  cash-sales status  is expressed  only  through  the  display.   Beside   the cash-sales status, a credit, a cash- receipt, a  payment  function can be extended through the check mode.

The ridge of the upper cladding layer is additionally separated and formed on the first cladding layer and the second cladding layer. A current cut-off layer with a predetermined width and a predetermined interval is provided on both side of the lower part of the second cladding layer.

Title: Ntsc digital color modulating apparatus and method
Inventor: HONG SEONG HUN
IPC: H04N5/208
Filed: 1993-11-30
Granted: 2001-09-17
Abstract: PURPOSE: An NTSC digital color modulating apparatus and method are provided to demodulate a modulated in-phase signal having the bandwidth of 1.5MHz and to improve resolution of the in-phase signal so as to output vivid colors. CONSTITUTION: An NTSC digital color modulator includes the first latch(21) for receiving a demodulated chrominance signal to latch a quadrature-phase signal according to the first clock, and the second latch(31) for receiving a demodulated chrominance signal to latch a demodulated in-phase signal according to the second clock. The modulator further includes the first low pass filter(22) for receiving the signal of the first latch to output a quadrature-phase signal in a predetermined frequency band, and a low pass filter(10) for accepting the signal of the second latch to output an in-phase signal in a predetermined frequency band. The low pass filter has the second low pass filter(11) for receiving the signal of the second latch, the first delay matching unit(12) for matching the output signals of the second latch and the second low pass filter with each other, a subtractor(13) for subtracting the output signal of the second low pass filter from the output signal of the first delay matching unit, an amplifier(14) for amplifying the output signal of the subtractor, and an adder(15) for adding up the output signals of the amplifier and the second low pass filter. The amplitude of the radio-frequency portion of the in-phase signal output from the low pass filter becomes identical to the amplitude of the low-frequency portion.
