Abstract: This invention relates to an apparatus configuration and a method of operation for fuel cells that use as fuel any carbon compound. These cells are built with anodes capable of storing and diffusing hydrogen, where the complete oxidation of the carbon fuel to carbon dioxide occurs, and cathodes that use atmospheric oxygen as an oxidant. An aspect of the invention is the deliberate occlusion of hydrogen in the anode during the operation of the fuel cells, in order to eliminate or greatly reduce the poisoning of the electrocatalyst. Fuel cells according to the invention will be more competitive with existing power sources in price, operational costs, power output, lifetime, volume and pollution emission. Implementation of the invention can also be used to upgrade old fuel cells and to detect and destroy carbon compounds in medical or pollution control applications.

Abstract: In a warping machine, once a temporary feed speed for a warping reed is set in synchronism with the speed of rotation of the warping drum, the winding thickness of the warp lap is detected several times and the feed speed is corrected depending on the number of revolutions of the warping drum and the winding thickness that results therefrom. The winding of the warp lap is then completed at the corrected feed speed. During a starting phase, a theoretically correct feed speed for at least the first revolution of the warping drum is derived from warp parameters, such as the total number of threads, the width of the warp and the yarn count. The winding thickness of the first warp section is continuously and contactlessly measured during a learning phase that follows the starting phase, or during the starting phase. For that purpose, a winding thickness measurement arrangement is held at a predetermined, substantially constant distance from the surface of the warp layer that has just been wound.

Abstract: A portable firearm employs a frame and an upper mechanism having a bolt and a sliding hammer. A barrel assembly is supported on the frame and has an axis, a muzzle and a breech. The sear transversely straddles the barrel assembly and can project above its axis for restraining the hammer. A trigger mechanism employs a reciprocatable member coupled to the sear for selectively operating the sear automatically or semi-automatically. An intervening member is mounted to reciprocate transversely to the axis of the barrel assembly. This intervening member can retract upon the hammer moving against the intervening member. The intervening member is bifurcated to straddle and reciprocate transversely to the axis of the barrel assembly.
