Title: DLC coating for earth-boring bit seal ring
Inventor: SCOTT DANNY E
IPC: E21B10/22
Filed: 2003-08-19
Abstract: A rolling cone cutter has a bearing pin 15 on which is mounted a cone 17. A bearing sleeve 21 rotates with the cone and a rigid ring 23 is biassed against the sleeve by an energizing ring 29. There is an excluder ring 31. One or both the inter-engaging faces of the sleeve and the ring 23 is coated with a layer of DLC material. The DLC material, or diamond-like carbon, is a form of meta-stable amorphous carbon or hydrocarbon compound with properties very similar to those of diamond. To form the layer on the face 27 of the ring 23, a first operation comprises the deposition of material trom an RF plasma, sustained in hydrocarbon gases, onto negatively biased ring 23. After heating, face 27 is etched by argon ion bombardment. Then one or more metallic interlayers is applied from a sputter source such as a chromium target. Lastly, acetylene is introduced and a plasma is ignited between face 27 and the chamber walls. The acetylene decomposes to form carbon atoms that coat face 27 on the metallic interlayer with DLC. During the entire coating process, the temperature will be maintained below the lowest transformation temperature of the ring 23. Other processes are suitable, including primary ion beam deposition of carbon items. The coating preferably has a thickness of 2 to 3 micrometers, the hardness is in the range from 2,000 to 5,000 Knoop.

Title: A device for purifying air by alternating pressure adsorption in molecular sieve beds.
Inventor: RITTNER WOLFGANG
IPC: B01D45/12
Filed: 2003-09-10
Abstract: A device for purifying air by alternating pressure adsorption in molecular sieve beds comprises at least one water separator 3,5 located between a source of compressed air 2 and the molecular sieve beds 8, the water separator 5 immediately upstream of the molecular sieve beds being a cyclone-type water separator. A pressure reducer 4 may be located upstream of the cyclone and purified air may be stored in a tank 9 before being passed to a consumption unit (not illustrated). The cyclone separator may be combined with a filter which retains particles of dirt and dust so that the molecular sieve bed are contaminated only to a very small degree. In use, the device may be used to purify air so as to increase its oxygen component and is especially suited for providing a supply of breathable gas in an aircraft. The use of a cyclone separator to remove water from the gas substantially reduces the amount and frequency of regeneration required for the molecular sieve beds compared with known devices.

Title: A Safety Razor
Inventor: KING WILLIAM ASHLEY
IPC: B26B21/40
Filed: 2003-11-17
Abstract: A razor head 2 has blade members 7 with straight front cutting edges 8 which are mutually parallel and lie in a cutting plane 8. Imaginary median surfaces 16 of the blade members 7 are continuously curved in the same sense away from the cutting plane 12, from the cutting edges 8 toward the rear edges. The handle 1 has a pair of fork arms 6, the distal ends of which are connected to the head at positions adjacent the respective ends of the head 2. Each fork arm 6 has a groove 49 allowing pivoting of the distal end about a pivot axis parallel to the head axis, the grooves 49 being mutually aligned on the same side of the forked end portion 4 of the handle 1. Each groove 49 is filled with a resiliently deformable material 54 which is deformed when a pivoting force is applied to the razor head 2 during shaving and which restores the razor head 2 to a normal position when the force is removed. The head 2 has undercut apertures 42 in rear abutment surfaces 43, and the distal ends of the fork arms 6 have detent elements 44 projecting forwardly from front abutment surfaces 46. The front and rear abutment surfaces 46,43 abutting against one another and the detent elements 44 engage in the undercut apertures 42 in such a manner that the head 2 is fixed relative to the distal ends of the fork arms 6, the distal ends being movable toward one another to disengage the detent elements 44 from the undercut apertures 42 and allow the head 2 to be removed from the handle 1.

Title: Gas vent with linked control members contra-rotating at a predetermined pressure differential
Inventor: GATLEY RICHARD
IPC: F24F11/04
Filed: 2003-12-04
Abstract: A vent 1 for gas flow control through an opening 2 has first and second control members 7,8, and a link 9 constraining the control members to pivot together in opposite rotational directions. The control members are mounted on pivots 10,13 which are offset relative to the centres of pressure and gravity of the control members so that differential pressure across the opening will exert a moment on the control members. The link 9 balances the moment of the first control member 7 with the moment of the second control member 8. A counter-balance weight 27 allows the control members 7,8 to pivot from the closed position to the fully open position at a predetermined pressure differential. The link may comprise radius arms 24,25 and a coupling arm 26, or meshed gear wheels (not illustrated). Stops 20,21 limit the open and closed positions of the control members 7,8. The control members 7,8 have edges 22,23 which overlap or engage when the control members are in their closed positions, to substantially close the opening 2. Embodiments with three or four control members are described. The vent may maintain pressure in a room to suppress the spread of fire, or arranged to release excess pressure in a room during release of gas to combat a fire.

Title: Imaging internal structures and correcting for motion artifacts
Inventor: HERK MARCEL VAN
IPC: A61B6/03
Filed: 2004-07-06
Abstract: A system for imaging the internal structure of a volume which varies periodically due to, for example, the breathing motion of the patient. The arrangement utilises a CT scanner to produce a series of projected images. The dataset is split into phase-correlated data sets, which are compared to each other and the relative transformation determined. This transformation then applied in reverse to bring the data sets back to a single phase. The whole data set is then used to reconstruct an image of that phase, thus eliminating image artifacts due to motion.

Title: Grouping nodes into zones satisfying a threshold
Inventor: WECHTER GABRIEL
IPC: H04Q7/34
Filed: 2004-09-22
Abstract: The invention discloses managing a network of nodes by grouping the nodes into zones as a function of relationships among the nodes, such that each zone satisfies a threshold that is based on an operational capacity of a discovery agent assigned to discover the network. The method includes partitioning the network into zones or sections for scalability and performance purposes, wherein real-world physical and logical relationships are captured or detected, and are accounted for in the partitioning process. It attempts to capture and/or take into consideration physical locality relationships that are common in network designs, such that zones along a routed path, or separated by one common router are merged. Aspects of the invention include combining or splitting zones to satisfy the threshold. The need for user involvement is nearly eliminated.

Title: DC lighting system with voltage capping
Inventor: HOLLAND JOHN PAUL
IPC: H05B39/04
Filed: 2004-10-14
Abstract: A dc lighting controller 10 has an input for receiving a dc drive voltage 12 and a circuit 14 for processing the drive voltage to provide a modified output, and for capping the maximum effective voltage of the modified output. The modification and capping may be performed by a pulse-width modulation circuit. The pulse-width modulation circuit may also be used to provide a dimming function. By providing a lighting controller 10 which performs voltage capping, the need for a voltage regulation circuit serving a full lighting circuit is avoided. This enables a modular system to be designed. A system using only a few controllers (30, figure 4) can then be set up as a low-cost way of providing voltage regulation, prolonging the life of the lighting units (11). The controller 10 is equally effective for implementing a system with many lighting units 11 or circuits and still avoids the need for centralised voltage regulation. The circuit 20 may also ramp the effective voltage up and down at turn-on and turn-off respectively.
