A ceramic wall-flow filter for filtering particulate matter from gases and methods for manufacturing such wall-flow filters are disclosed. The filter includes an array of porous ceramic walls defining a pattern of end-plugged inlet and outlet cells, and heat absorbing elements disposed within at least some of the outlet cells such that a bulk heat capacity of the outlet cells is greater than a bulk capacity of the inlet cells. The heat absorbing elements increase a bulk heat capacity of the filter without substantially interfering with a flow of gas through the porous ceramic walls by allowing thinner walls. According to the method, during the step of extruding or thereafter, heat absorbing elements are formed within at least some of the outlet cells such that a heat capacity of the outlet cells is greater than the inlet cells.

A screw conveyor for loose material comprises a tubular casing having a first part which is axially rotatable on command with respect to a second part. The first part is provided with openings through which the material can be introduced into the casing. A screw, internal of and coaxial to the casing, can rotate on command about its own axis and thus convey the material. A helical conveyor device which is solid in rotation with said first part of the casing, conveys the material towards the openings in first part of the casing. There is a hollow jacket between the conveyor device and the second part of the casing, through which the material passes. The invention provides greater efficiency in collecting and removing loose material from a pile.

The SCRUB'N'BAG is a personal bathing accessory which is composed of polyester mesh material. There is a cord channel around the top opening of the bag through which a nylon cord is threaded. Once the soap bar is placed in the bag, the cord is drawn to close the top of the bag. The excess nylon cord can be placed around the wrist and the vinyl slide is used to comfortably secure the bag to the wrist, eliminating the need to ever have to retrieve a dropped bar of soap again. The material at the top half of the bag can be used instead of a washcloth, or the bather may hold the lower half of the bag, which contains the bar of soap, and wash the body. The mesh polyester material allows the soap suds to pass through while also providing gentle exfoliation of skin.

The invention relates to a preparation method of Ageratina-adenophora-base high-specific-area activated carbon, belonging to the field of environmental protection. The method comprises the following steps: uniformly mixing KOH and an Ageratina adenophora carbonization material in a solid-phase state, filling into a ceramic crucible, and putting into a microwave high-temperature reactor; introducing nitrogen to evacuate air in the furnace, heating under microwaves to the last fewer minutes, quickly blowing CO2 into a guide tube communicated with the bottom of the ceramic crucible, and meanwhile, starting an ultrasonic generator; after finishing heating, washing the activated material with water, and recovering the residual KOH activator; and sequentially carrying out acid washing, water washing and drying to obtain the high-specific-area activated carbon. By using the Ageratina adenophora as the raw material, the method uses the CO2 bottom blowing mode to enhance the activation effect of the carbonization material, thereby lowering the production cost of the activated carbon, relieving the environmental pollution, changing harmful substances and waste into valuable substances and implementing comprehensive utilization of natural resources. The high-specific-area activated carbon can be effectively used in the fields of adsorptive collection of gasoline and other organic substances in automobile exhaust emissions and fuel system volatile substances, solvent recovery and the like.
