| 20110073488 | COPPER CHLORIDE/COPPER BROMIDE DISINFECTOR FOR SWIMMING POOLS AND CONTROL METHOD THEREOF - A two-in-one copper chloride/copper bromide disinfector and a method of controlling the same. In operation, when copper is released, the positive and negative electrodes of a copper billet are periodically reversed, while the positive and negative electrodes of a titanium plate/graphite polar plate are in an uncharged state. When chlorine/bromine is released, the positive and negative electrodes of a titanium plate/graphite polar plate are periodically reversed, while the positive and negative electrodes of the copper billet are short-connected, then connected to the negative electrode of the titanium plate/graphite polar plate, or applied thereon with an electric voltage that is lower than the electric voltage of the negative electrode of the titanium plate/graphite polar plate. With this method, the copper billet out of operation is shorted-connected to the negative electrode of the titanium plate/graphite polar plate or connected to an electric voltage that is lower than that of the negative electrode. Thus the release amount of copper ions is controllable, the volume of the disinfector is reduced, and the corrosion between the positive and negative electrodes of the copper billet is uniform. | 03-31-2011 |
| 20110073410 | Swimming Pool Ladder With a Barrier - The present disclosure provides a swimming pool ladder with a barrier. The ladder includes two ladder sections. A top platform for supporting is connected between the upper portions of the two ladder sections and disposed above the swimming pool. The two ladder sections are respectively positioned inside and outside the swimming pool. The ladder section includes two parallel-disposed rails and a plurality of steps. The plurality of steps are mounted at intervals along the two rails from top to bottom. A barrier is provided that is perpendicular to the inner side face of the first ladder section. The barrier has a triangle shape, one edge of which is adjacent the inner side face of the first ladder section and fixed on at least two steps through at least two connectors and another edge is adjacent the inner sidewall of the swimming pool. The top end of the barrier is spaced from the top platform by a distance and the bottom end is adjacent the floor of the swimming pool. | 03-31-2011 |
| 20110072574 | Swimming Pool Ladder Cover - A swimming pool is provided with a swimming pool ladder. A swimming pool ladder cover covers the steps and other portions of the swimming pool ladder. | 03-31-2011 |
| 20110035270 | Network Advertisement Transmission Device and Method - A technique of integrating advertisements through broadcasting with that through a network out of advertisement media and particularly a technique of producing high advertisement effectiveness by automatically synchronizing advertisement timing is provided. A network advertisement transmitting method for transmitting advertisement data outputted at the user terminal device, comprising in advance a broadcast information database | 02-10-2011 |
| 20100024342 | Retainer Frame for a Swimming Pool - The present invention provides a retainer frame of an outdoor above ground pool, which includes a plurality of posts and a plurality of sets of beams, connected between pairs of adjacent posts to form a polygonal shaped retainer frame. Each beam has two end portions, and each post has one or more receiving ports for receiving the end portions of a set of beams. The retainer frame also includes a plurality of locking members for locking the end portions of the set of beams in the receiving ports of the corresponding post. The beams are capable of swinging around a longitudinal axis of the posts within a range of swinging motion so that the same components (posts, beams and locking members) can be used to form polygonal shaped retainer frames having different numbers of sides. | 02-04-2010 |
| 20080209643 | AIR-INFLATED MATTRESS - A double air-inflated mattress having an upper chamber and a lower chamber, the upper chamber having a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, the outer shroud band connecting the top and bottom layers to form an inflatable bladder; a middle layer below said top layer partially sealed to the top layer to form a plurality of sealed or half-sealed cavities, in which some or all of said cavities are in fluid communication with the inflatable bladder, the lower chamber having a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, said outer shroud band connecting the top and bottom layers to form an inflatable bladder. Each chamber of the double mattress may also have a middle shroud band and an inner shroud band, both of said middle shroud bands being separately welded to the outer shroud bands and the inner shroud bands to form a plurality of closed or half-closed cavities, some or all of said cavities being in fluid communication with its respective inflatable bladder to form a plurality of air pockets on the outer shroud bands of the double air mattress. | 09-04-2008 |
| 20080209642 | AIR-INFLATED MATTRESS - An air-inflated mattress, comprising a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, wherein said shroud band connects the top and bottom layers together to form an inflatable bladder. A middle layer below said top layer is partially sealed to the top layer to form a plurality of sealed or half-sealed cavities, in which some or all of said cavities are in fluid communication with the inflatable bladder, via a plurality of air vents in the middle layer, creating air-pockets arrayed on the top surface of the air mattress. The mattress may also comprise a middle shroud band and an inner shroud band, with a plurality of joint spots welded between the shrouds, creating a plurality of half-sealed cavities on the surface of the outer shroud band, with means to pass air between the inflatable bladder and the cavities, which slows the spreading speed of the air to the bladder and the cavities, so that the air mattress is even and level and the supporting strength of the air mattress is greatly improved. | 09-04-2008 |
