For application of active substances to a wound surface a porous padding (12) is provided upon the wound (10), which is sealingly covered over with a foil (14). A fluid active substance is introduced into the padding (12) via a supply line (22) and is then suctioned out of the padding (12) via a removal line (26). Closure mechanisms (32, 34) control the introduction of the active substance and the suctioning off of the active substance in the manner, that the active substance after being introduced remains for a predetermined dwell time in the padding (12), before it is suctioned off. After the suctioning off the vacuum in the padding (12) is maintained for a certain time period, before renewed introduction of the active substance. The opening of the closure mechanisms (32, 34) are temporally controlled to occur slowly.

An accumulator for an air-conditioning (refrigeration or heat pump) system is designed to reduce flooding due to greater effective internal volume while at the same time incorporating an internal heat exchanger for better system performance, and providing better evaporation and controlled thermal properties. The accumulator embodies an outer housing that co-axially surrounds an inner liner. The inlet directs the refrigerant into the inner volume formed by the liner, wherein the liquid refrigerant and compressor oil are contained and insulated from the wall of the outer housing. A heat exchanger is arranged in the annular space between the outer housing and the inner liner and circulates a flow of condensate therethrough before delivering it to the expansion device. In this way the condensate is cooled for higher performance and at the same time refrigerant passing out of the accumulator is vaporized more completely.

A wound therapy combination comprising a suction head and a surgical drape. The suction head comprises a planar flange portion and a tubular connector piece on a first face that communicates with an aperture extending to a second face. The second face is formed with projections that define flow channels for facilitating flow of liquids to the aperture.

A dust collecting apparatus for a vacuum cleaner has a first cyclone dust collecting part and a second cyclone dust collecting part that are arranged substantially parallel with respect to an air inflow opening of a vacuum cleaner main body, and may be mirror images of each other. The first cyclone dust collecting part comprises a first suction opening and a first discharge opening, and the second cyclone dust collecting part comprises a second suction opening and a second discharge opening. The first and second suction openings are connected with the air inflow opening of the vacuum cleaner main body, and the first and second discharge openings are connected with a vacuum suction chamber of the vacuum cleaner main body. Accordingly, a dust collecting apparatus for a vacuum cleaner can be realized, having an advanced suction capability and dust separation capability.

An open-air filtration device cleans swimming pools and hot tubs in an efficient, reliable manner. An open-air filter with a suction chamber unit comprises two scrubbing brushes and an impeller powered by a motor drive. Water containing debris is pumped to a level above the swimming pool or hot tub surface. The debris containing water is discharged through a spout into a filter tube. A filter element associated with the filter tube, and open to atmosphere filters the debris containing water by gravitational forces solely. The spout and filter tube are, optionally, attached to a pole that manually propels the suction unit. They may alternatively be attached to a floating platform that floats on the water surface of the pool or hot tub. If filter efficiency decreases, the water level in the filter tube rises, indicating that the filter element must be replaced. A rise in water level is visually observed or detected automatically and communicated using a visible or audible alarm.

The invention discloses a nitride ceramic coating applied to a lithium ion battery. The nitride ceramic coating consists of the following components in parts by weight: 2-10 parts of adhesive, 10-40 parts of nitride ceramic particles, 0.5-3 parts of thickening agent, 0.05-2 percent of dispersing agent and the balance of solvent. The nitride ceramic coating is prepared by the following steps: (1) preparing slurry, namely uniformly mixing and stirring the solvent, the dispersing agent and the thickening agent, standing, defoaming, adding the nitride ceramic particles, uniformly dispersing and forming slurry A; (2) dispersing at high speed, namely dispersing the slurry A at high speed, then adding the additive, uniformly stirring, performing vacuum defoaming, and screening to form slurry B; (3) coating, namely coating the slurry B on an edge of the anode and/or the surface of the cathode and/or a diaphragm in the lithium ion battery, and drying at the temperature of 60-120 DEG C. According to the nitride ceramic coating, the liquid absorption capacity and liquid retaining capacity of the diaphragm or the pole piece can be effectively improved, the hydrofluoric acid resistance and thermal shock resistance of the pole piece or the diaphragm are improved, and a better heat barrier effect is achieved.
