Abstract: L'invention concerne un procédé de réduction d'un matériau particulaire contenant du minerai de fer, lequel comprend au moins deux étapes au cours desquelles du gaz de réduction est conduit à travers au moins deux zones de réaction disposées l'une derrière l'autre en série et formées par le matériau particulaire en mouvement, et le matériau particulaire traverse les zones de réaction dans l'ordre inverse, par rapport au gaz de réduction. Le matériau particulaire est chauffé dans la première zone de réaction et soumis à une réduction dans l'autre zone de réaction. Pour que l'on puisse atteindre une température de préchauffage maximale sans formation de magnétite, le gaz de réduction conduit à la première zone de réaction est conditionné de sorte qu'il n'y ait pas ou presque pas de réduction, mais que la température de préchauffage soit cependant atteinte pour le matériau particulaire dans la région limite du début d'une réduction, le degré d'oxydation du gaz de réduction étant augmenté et/ou la température du gaz de réduction étant abaissée. Dans la seconde zone de réaction, destinée au minerai de fer, la température est maintenue à une valeur d'au moins 600· C, de préférence dans une plage comprise entre 600 et 700· C, en particulier entre 620 et 660· C, et le matériau contenant de l'oxyde de fer est réduit en wustite.

Title: Determining femoral cuts in knee surgery
Inventor: RICHARD ALAIN
IPC: A61B34/20
Filed: 2003-04-30
Granted: 2013-01-15
Abstract: A system for determining a distal cut thickness and posterior cut thickness for a femur in a knee replacement operation stores data relating to size and shape of femoral implants. A tracking device tracks said femur and a tibia in a reference coordinate system. A registration module is used for registering a femur representation, a tibia representation and a femoral posterior cut to said reference coordinate system. A gap measurement module is adapted to measure an extension gap and a flexion gap using said femur representation and said tibia representation as registered in said reference coordinate system and adapted to generate measurement data. A cut thickness computing module receives said measurement data and calculates: a posterior cut thickness for said femur using said extension gap and said flexion gap and taking into account a distal thickness and posterior thickness of a femoral implant; and a distal cut thickness based on the flexion gap resulting from the femoral posterior cut registered in said reference coordinate system. An output device outputs said measurement data and calculated data calculated by said computing module.

Title: Method and apparatus for resolving deadlock of auto-negotiation sequence between switches
Inventor: YAMAUCHI TOSHIRO
IPC: H04J3/14
Filed: 2004-09-29
Granted: 2011-05-31
Abstract: A transmission repeater has a function of recovery to normal out of the deadlock state of auto-negotiation sequence between switches. The switches exchange auto-negotiation configuration codes via first and second transmission repeaters for a state transition. The first transmission repeater monitors auto-negotiation configuration codes among data transmitted from the opposed switch, and when detecting more than a predetermined number of configuration codes of auto-negotiation having been transmitted during a given period of time, determines that the auto-negotiation sequence between the switches is at a deadlock, and reports it to the second transmission repeater , which then disconnects optical signals from the sending end of the second transmission repeater to the switch for more than twice the propagation time of signals between the switches, thus resolving the deadlock between the switches.

Abstract: Systems and methods verify the content of an electronically transmitted claim, such as a healthcare claim by intercepting the claim, reviewing the claim's contents, and comparing the claim to pre-established claim criteria established by a payer or both a healthcare service provider and payer. If the claim contains the appropriate content the claim is forwarded to its intended recipient, typically a payer such as an insurance company or government healthcare payer; otherwise the claim may be returned to the sender, e.g., a pharmacy, with an indication that it does not contain the correct content. Additionally, the claim may be edited by the system and forwarded in correct form to its intended recipient.

Title: Screwdriver bit locking mechanism
Inventor: FRUHM HERMANN
IPC: B23B31/103
Filed: 2005-02-18
Granted: 2008-11-18
Abstract: A bit locking mechanism for a screwdriver having a shaft with a bit chuck formed in one end of the shaft. A slot in the shaft intersects a rearward portion of the chuck. A lever is pivotally mounted in the slot, and extends parallel to the shaft. A tab on the lever's forward end has a rearward face substantially perpendicular to the lever's longitudinal axis. A spring normally biases the tab into the chuck. The locking mechanism is used with a bit having a rearward collar with a length substantially equal to the difference between (i) the distance from the lever's pivot point to the tab's rearward face, and (ii) the distance from the lever's pivot point to the chuck's rearward end. The collar's forward face is substantially perpendicular to the bit's longitudinal axis. As the bit is inserted into the chuck, the bit's rearward end slides under the lever, overcoming the spring's bias and pivoting the lever into a bit insert/release position. When the collar's forward face moves rearwardly of the tab's rearward face, the spring pivots the lever into a closed position in which the tab protrudes into the rearward end of the chuck, with the tab's rearward face latched against the bit's forward face, preventing unintended withdrawal of the bit from the chuck.

Title: System and method for improving the thermal efficiency of a heating system
Inventor: SPECHT WERNER
IPC: F23L5/02
Filed: 2005-10-28
Granted: 2010-04-20
Abstract: A system and method for providing a heating system with good thermal efficiency by adjusting combustion air flow in response to fuel-input rate changes over a wide range. An AC motor operates in a slip mode whereby as the fuel-input rate changes, the combustion air density is affected. In response, changes in the load and thus the speed of the motor occur. Consequently, the quantity of combustion air flow increases in response to a fuel-input rate increase. The motor switches to a synchronous speed in response to the fuel- input rate reaching a set value, e.g., 70 percent of maximum rate.

Title: Media registration systems and methods
Inventor: WILLIAMS LLOYD A
IPC: B41F21/00
Filed: 2006-07-25
Granted: 2009-10-13
Abstract: Embodiments herein measure current/voltage levels of a drive motor when media is in contact with a drive roller so as to determine the drive force imparted by the drive rollers on the media. Then, embodiments herein can reference the predetermined relationship between roller drive force and media/drive roller velocity ratios to determine a difference between the velocity of the drive roller and the velocity of the media based on the drive force. Once this velocity difference is determined, embodiments herein can change the current/voltage levels being applied to the drive motor if the actual velocity of the media is different than the intended velocity of the media so as to correct the velocity of the media. Thus, when referencing the predetermined relationship, embodiments herein produce a velocity ratio correction factor. This velocity ratio correction factor can be applied continuously during any velocity profile of the drive motor, or it can be used to calculate the accumulated error in sheet position and then to apply a correction near the end of the velocity profile.
