Title: Heating method of grill of electronic range having grill function
Inventor: LEE IN-KYU
IPC: F24C7/02
Filed: 1990-08-24
Granted: 1992-11-06
Abstract: The method is for heating the grill of the microwave oven  by controlling a conventional convection heater and a circulation fan motor without using a special  grill  heater.  The  grill  heating method comprises the steps of; actuating a motor (26) for a rotary table and the convection heater (30) if the grill heating function is  selected;  detecting  temperatures  of  a  convection  heating chamber (28); actuating the circulation fan motor  (31)  when  the detected temperature reaches an upper limit  value;  stopping  the circulation fan motor (31) when the detected temperature falls  to a lower limit value; stopping the motor (26)  and  the  convection heater (30) after repeating the preceding steps.

Inventor: AN KYONG-HAN
IPC: E02D33/00
Filed: 1991-07-09
Granted: 1994-03-24
Abstract: The pile load tester for finding the ground condition for a building construction has a pile shoe (2) and a core (30) on the bottom end of a pile frame (1) having on its inner side a catch ring projection (4), the pile shoe (2) having on its top an oil jack (8) equipped with an auxiliary oil jack (8a) for actuating the core (30) and also having a lock member (9) for being caught by the ring projection (4). The operation of the jack moves upward the lock member to be caught by the ring projection and further move the pile frame upward and push the pile shoe downward. The gradual increase of the jack oil pressure makes the pile frame in movement to break the resistance of the surrounding earth and bring a sudden rapid movement whose upper travel distance is measured. At the same time, the oil pressure is determined to be the maximum friction force of the surrounding. Then the auxiliary jack is operated to increase the pressure until the core makes a sudden rapid down movement. The pressure at this time is determined to be the maximum tip resistance.

Title: Ultraviolet absorbing green tinted glass
Inventor: GULOTTA JOSEPH A
IPC: C03C4/08
Filed: 1991-07-29
Granted: 1994-03-14
Abstract: A green tinted, ultraviolet absorbing glass is obtained by the addition of colorant to a standard soda-lime-silica base glass composition and a colorant includes less than 0.5 weight percent of cerium oxide (CeO2), greater than 0.85 weight percent of total iron expressed as Fe2O3 and a ratio of ferric iron expressed as FeO to total iron of less than 0.275. The glass has a low ultraviolet transmittance, viz., no greater than 31 percent over the wavelength range of 300 to 390 nanometers at a reference glass thickness of 3.9 millimeters. An advantage of the glass of this invention over competing ultraviolet absorbing glass is the use of larger amounts of total iron and smaller proportions of iron in the ferrous state to obtain the low ultraviolet transmittance. In this manner, the amounts of cerium oxide which is expensive is reduced.
