Vacuum cleaner having a cyclone type dust collecting apparatus

A vacuum cleaner includes a cleaner body, a suction brush, through which air and contaminants are drawn in, and a cyclone type dust collecting device. The cleaner body has a motor driving chamber and a dust collecting chamber in communication with the motor driving chamber. The cyclone type dust collecting device is mounted in the dust collecting chamber and separates by centrifugal force the contaminants from the air. The cyclone type dust collecting device includes a hollow cylindrical cyclone body having an open top, a closed bottom, and a contaminant outlet. The open top allows air and contaminants into the cyclone body, where the contaminants are separated from the air by centrifugation. The contaminants are then discharged from the cyclone body through the contaminant outlet. The cyclone type dust collecting device further includes a contaminant receptacle for collecting the contaminants discharged through the contaminant outlet, a base member hingedly connected to the contaminant receptacle, and a cover for covering the top of the cyclone body. The cover has an air inlet passage, through which air and contaminants drawn in through the suction brush enter into the cyclone body, an air outlet passage, through which the air is discharged from the cyclone body, and a contaminant separating grill. The grill extends downward from the air outlet passage into the cyclone body and has a plurality of fine holes.

Honeycomb filter for exhaust gas decontamination, adhesive, coating material and process for producing honeycomb filter for exhaust gas decontamination

An object of the present invention is to provide a honeycomb filter for purifying exhaust gases which makes it possible to alleviate a thermal stress generated due to occurrence of a local temperature change and which is less likely to generate cracks and superior in strength and durability, an adhesive that has a low thermal capacity and is capable of alleviating the thermal stress, a coating material that has a low thermal capacity with a superior heat insulating property and is capable of alleviating the thermal stress, and a manufacturing method of the honeycomb filter for purifying exhaust gases that can improve precision in the outside dimension, and reduce damages in the manufacturing processes.
The present invention relates to a honeycomb filter for purifying exhaust gases, having a structure in that a plurality of column-shaped porous ceramic members, each having a number of through holes that are placed side by side in the length direction with partition wall interposed therebetween, are combined with one another through adhesive layers so that the partition wall that separate the through holes are allowed to function as a filter for collecting particulates, and in this structure, the thermal expansion coefficient αL of the adhesive layer and the thermal expansion coefficient αF of the porous ceramic member are designed to have the following relationship:

Filtration monitoring and control system

PCT No. PCT/AU96/00144 Sec. 371 Date Jan. 12, 1998 Sec. 102(e) Date Jan. 12, 1998 PCT Filed Mar. 15, 1996 PCT Pub. No. WO96/28236 PCT Pub. Date Sep. 19, 1996A method and apparatus for determining the fouling effect of a feedstream on a filter having known characteristics disclosed. The method comprises passing the feedstream through a filter (5) having known characteristics; determining the change in resistance to flow of the feedstream across the filter, either continuously or over a number of time intervals and from this data, calculating a feed fouling index (FFI) representative of the fouling characteristics of the feedstream with respect to the filter. A method and apparatus for monitoring the operation of a filtration system is also disclosed the method comprising sampling system parameter values at selected locations within the filtration system at a predetermined sampling rate; generating a parameter profile characteristic from the sampled parameter values at predetermined intervals of time; and analysing the parameter profile characteristic to determine correct operation of the filtration system. A further method and apparatus of monitoring and controlling a filtering system based on backwash efficiency is also disclosed, the method comprising determining resistance values of filtering elements used in the filtering system at predetermined times during the backwash cycle of the system by monitoring a number of operating parameters of the system; calculating a backwash efficiency value representative of the efficiency of the backwash cycle of the filtering system using the resistance values determined; and controlling the operation of the filtering system in dependence on the value of the backwash efficiency calculated.
