Abstract: A low impedance polarity conversion circuit for driving a load with a DC power source is disclosed. The DC power source has a first pole from which a first DC signal originates and a second pole from which a second DC signal originates. The first DC signal has a voltage greater than a voltage of the second DC signal. The conversion circuit includes a circuit output node through which an output DC signal is delivered from the conversion circuit to the load. The conversion circuit also includes a charge conditioning circuit for generating third and fourth DC signals. The third DC signal has a voltage greater than the first DC signal voltage and the fourth DC signal has a voltage less than the second DC signal voltage. A rectification circuit includes first and second inputs for attachment to the first pole and the second pole. A Field- Effect Transistor (FET) bridge is electrically connected to the first and second inputs. The FET bridge includes first and second pairs of cooperating FETs. The third voltage controls a first of the first pair of FETs and a first of the second pair of FETs. The fourth voltage controls a second of the first pair of FETs and a second of the second pair of FETs. The FET bridge is for rectifying the first and second DC signals in order that the output DC signal is the same polarity irrespective of whether the first input is attached to the first pole or the second pole.

Title: Method of removing mercury from combustion exhaust gases
Inventor: WINKLER HERMANN
IPC: B01D53/64
Filed: 2007-12-21
Granted: 2012-04-17
Abstract: The present invention relates to a method of removing mercury from combustion exhaust gases from combustion plants, such as power stations or waste combustion plants. Previous methods for removing mercury from combustion exhaust gases are structurally complex and cost intensive. The object resulting from this problem is solved by a method, in which the mercury-containing combustion exhaust gases are brought into contact with an adsorption agent, whereby the mercury is substantially adsorbed by the adsorption agent during this contact. After the adsorption has occurred the adsorption agent is separated from the combustion exhaust gases and added to an aqueous solution containing an oxidising agent, whereby the adsorbed mercury goes into solution as Hg2+. The Hg2+-containing solution is subsequently separated from the adsorption agent and the Hg2+ is then removed from the solution. This conduct of the method enables the mercury to be removed from the combustion exhaust gases in a simple and economical manner.

Abstract: A method of assembling parts to form an aircraft component, in which a first surface of a first part (for example a wing skin (12) ) is to be positioned in the assembly adjacent to a second surface of a second part (for example a rib foot (8) ) . The method comprises the steps of taking measurements of the first part (12), taking measurements of the second part (8) with a laser (15A) , and calculating the size and shape of the space that will be generated when the first and second parts are assembled. A shim (20) of varying thickness in dependence upon the results of the calculating step is manufactured, for example by stereolithography, and the first and second parts are assembled with the shim (20) positioned between the first and second parts, the varying thickness of the shim (20) compensating for a varying spacing of the first and second surfaces .

Granted: 2012-10-30
Abstract: A crane return system is used for returning a crane component to a home position when there is a loss of power. A crane includes a bridge with a plurality of main wheels adapted to travel along at least one rail. The crane return system includes a plurality of auxiliary drive wheels supported by the bridge, the auxiliary drive wheels movable between a first position, in which the auxiliary drive wheels are recessed from the rail, and a second position, in which the auxiliary drive wheels are in contact with the rail. When power is supplied to the crane return system the auxiliary drive wheels are in the first position. A hydraulic fluid pressure vessel stores hydraulic fluid, wherein a substantially fixed mass of hydraulic cylinder is interconnected with the auxiliary drive wheels and selectively fluidly communicates with the hydraulic fluid pressure vessel. When power is lost to the crane, hydraulic fluid is supplied to the hydraulic cylinder to extend the hydraulic cylinder and thereby move the auxiliary drive wheels from the first position to the second position. A drive motor is interconnected with the auxiliary drive wheels and selectively fluidly communicates with the hydraulic fluid pressure vessel. When the auxiliary drive wheels are in the second position, hydraulic fluid is diverted from the hydraulic cylinder and supplied to the drive motor to rotate the auxiliary drive wheels and move the bridge toward a home position.

Abstract: The present invention relates to a process of edging a lens comprising forming a lens-protective transparent coating layer on the surface of the lens. When the lens coated with a transparent coating layer comprising a fluorine-containing elastomer and optionally a fluorine-containing organosilane compound and having a surface energy of less than 15 mJ/m2 is edged, the scratch of lens during handling, the damage of lens caused by chemical contaminants, and lens off-centring phenomena can be prevented. Further, such an edging process requires no adhesive tape, making the process simple, and prevents the contamination of the lens surface. Further, the inventive transparent coating layer makes it possible to measure the diopter of lens exactly owing to its transparency and it is manually removable without a chemical.

Abstract: Du nickel entraîné dans le minéral sulfuré tel que la pyrrhotine est modifié afin de se dissoudre dans de l'acide de lixiviation dans une procédure à deux étapes. Tout d'abord, une suspension épaisse du minéral et de l'acide est activée par oxydation. Ladite étape est mise en oeuvre à un moment T1 par électrolyse; ou dans une variante, chimiquement, par addition, par exemple, d'un acide oxydant au minéral. Après activation, la suspension épaisse est conservée dans des conditions anoxiques pendant un temps T2. Pendant le temps T2, le sulfure commence à se dissoudre beaucoup plus rapidement, et la dégradation rapide du sulfure permet au nickel de se dissoudre et d'être ainsi lixivié du minéral. Le nickel dissous est extrait de l'acide de lixiviation par exemple par extraction par voie électrolytique.
