Abstract: An antenna includes a first column of main radiating elements, each main radiating element configured to operate in a first operating frequency band and a first auxiliary radiating element. The first auxiliary radiating element is adjacent a first main radiating element in the first column of main radiating elements, and the first auxiliary radiating element is configured to radiate an electromagnetic wave that is substantially antiphase to an electromagnetic wave radiated by the first main radiating element.

Abstract: A boltless fastener assembly for a heavy haul railway with an axle load of 35-40 tons includes a pre-embedded steel holder, an e-clip, an insulated gauge block and a rubber pad. A clamping leg-heel end of the e-clip is provided with an L-shaped retaining end. The pre-embedded steel holder is improved to adapt to the e-clip, and an opening is formed at a portion of the pre-embedded steel holder close to the clamping leg-heel end of the e-clip, so that the e-clip can be installed normally. During normal installation, the L-shaped retaining end of the e-clip does not contact the pre-embedded steel holder. When the rail undergoes large torsional deformation, the L-shaped retaining end on one side of a rail moves upward to contact an upper edge of the opening of the pre-embedded steel holder or engages with a second heel end.

Abstract: A method of producing a pre-bent wind blade, includes: obtaining a pre-bent curve of a straight wind blade; and producing a bent wind blade according to the pre-bent curve, in such a manner that under a rating wind speed, the wind blade extends to be straight, so as to increase energy yield annually.

Abstract: An electrochemical storage cell having a coiled core is disclosed. The coiled core includes a cathode sheet, an anode sheet, and a separator sheet. An anode connector is connected with the anode sheet at a first end of the coiled core and a cathode connector is connected with the cathode sheet at a second, opposite end of the coiled core. The coiled core has a length Lcore and a width Wcore and each connector has a width Wconnector. The length of the coiled core Lcore, width of the coiled core Wcore, and width of each connector Wconnector have the relationship 0<(Wcore?Wconnector)/Lcore<0.37.

Abstract: A battery system having interconnected battery packs is disclosed. Each battery pack includes a plurality of rectangular prismatic shaped cells. Each cell includes a positive terminal at one end and a negative terminal at the other end. The cells are housed in a battery pack housing in a side-by-side manner. The cells may be electrically connected in series so that the positive terminal for a cell extends toward and contacts the negative terminal of an adjacent cell and the negative terminal for the cell extends toward and contacts the positive terminal of another adjacent cell.
