Batteries based on lead chemistry, e.g., lead-acid batteries, are substantially improved through the use of a particular positive material. This material is formed by the electrochemical conversion of tetrabasic lead sulfate (TTB) where this TTB is synthesized at a pH in the range 9.3 to 12 and under reaction conditions that provide a substantial excess of sulfate to the reactive lead. The resulti...

The X-ray tube arrangement has an anode system, to which an anode is allocated and a cathode system for delivering a focussed electron beam, which is aligned on the anode. The anode arrangement (10, fig.1) is assigned an anode target (12b), which accelerates the electron beam, and produces X-rays with the electron impact on the anode target. The anode target has a recess depth (28), which is cut f...

The arrangement has road vehicles equipped with a sensor (51) to measure the distance between a vehicle and the one in front. The sensor output is used by a controller (52) to regulate the speed of the vehicle and a separate unit (53) allows control of the start stop mode. The controller has the output applied to a servo motor that adjusts the air flow into the fuel system.
