Abstract: A method for controlling a drying operation of a combined sensing type clothes dryer including a drum, a heat exchanging fan, a motor, a heater, a temperature sensor and a humidity sensor, the sensors being disposed between the drum and the heat exchanging fan, comprising the steps of calculating an average value of the sum of a temperature variation per unit time detected by the temperature sensor and a humidity value sensed by the humidity sensor, both of which is detected when a predetermined time (t.sub.SH) has been elapsed from the beginning of the drying operation, determining the fabric quantity of clothes as one of a small fabric quantity, a large fabric quantity and an excessive fabric quantity, based on the calculated average value, and controlling the drying operation, based on the determined fabric quantity. Taking into consideration the ambient temperature, the fabric quantity is determined, thereby capable of preventing an occurrence of an error of the fabric quantity determination.

Abstract: A bubble column reactor with at least one radial dispersing device to radially sparge a gas phase into a liquid phase in the bubble column. The reactor comprises four parts: bubble column body 4, radial dispersing device, a mounting plate, and a head plate. The radial dispersing device is employed to radially disperse the gas phase into the liquid phase. It has a porous wall and an outer threaded port 2 and is vertically installed in the bubble column 4. A mounting plate is employed to allow the dispersing devices 1 to be vertically installed. A head plate 8 is employed to cover the bubble column 4 and have ports 9 for sampling, exhaust gas and sensors. The bubble column reactor according to this invention provides advantages in that it can generate small bubble sizes, thus increase the residence time of the gas phase even under relatively high gas velocities and also relatively high viscosities of the liquid reactant, thereby improving the mass transfer performance of the reactor.

Abstract: A midsole for footwear comprises an U-shaped shock absorbing device including a transparent housing, a plurality of tubes, letters or designs supported on a basic body, and a connecting member. The connecting member fixes the basic body to the transparent housing. The shock absorbing device will not twist and move during walking, will provide an excellent cushioning function and will have a fashion effect.
