Title: Lubricant pump and cone movement dampener
Inventor: KOFFLER KERRY
IPC: E21B10/24
Filed: 2004-08-19
Abstract: A lubricant pump and cone movement dampener system for a rolling cone cutter of an earth-boring bit is disclosed. The system includes an axial bore passing through the end of journal pin. The axial bore is fitted with a unidirectional valve and is in fluid communication with the bit's lubricant and with a grease passage. Lubricant, such as a grease, is pumped through the grease passage in the cone cutter, where it passes through the valve, out of the bore, and into the journal gap formed by the interior of the cone cutter and the exterior of the journal pin. Axial movement of the cone caused by formation forces acting upon the cone cutter as it rotates in the borehole causes more lubricant to be drawn into the journal gap. When the cone moves axially back in the opposite direction, heated lubricant in the gap is expelled from the gap via holes within the ball race of the journal pin. The system cycles cooler grease through the gap, dampens axial cone movement and reduces damage to the journal seal.

Abstract: A method, computer program product, and data processing system for constructing a self-managing distributed computing System comprised of "autonomic elements" is disclosed. An autonomic element provides a set of services, and may provide them to other autonomic elements. Relationships between autonomic elements include the providing and consuming of such services. These relationships are "late bound," in the sense that they can be made during the operation of the system rather than when parts of the system are implemented or deployed. They are dynamic, in the sense that relationships can begin, end, and change over time. They are negotiated, in the sense that they are arrived at by a process of mutual communication between the elements that establish the relationship.

Abstract: An apparatus (2) for steering a nosewheel on an aircraft, or the like, while the aircraft is on the ground. The apparatus includes a steering shaft (20) that engages a cluster (40, 50) of gears and transfers torque from a steering command to the gears. The steering shaft is rotatable from a centered position in response to steering torque. A centering mechanism (6) imparts a counter-torque on the cluster of gears to restore the steering shaft to the centered position when steering torque is released. The gear cluster comprises two drive gears (42, 52) that accurately guide the steering shaft to the centered position under the influence of the centering mechanism. The gear cluster is configured to minimize and compensate for gear wear, permitting accurate and consistent centering of the main shaft each time a steering torque is released.

Title: Method for transmitting optical polarization multiplex signals
Inventor: SPINNLER BERNHARD
IPC: H04B10/61
Filed: 2003-08-13
Abstract: Binary signals (A, B, C, D) are converted at the transmission end into two optical signals (QPS1, QPS2) which are combined into a polarization multiplex signal (PMS) and are then transmitted. The transmitted polarization multiplex signal (PMS) is divided at the receiving end into two polarized signal parts (PS1, PS2) which are converted in a linear manner into orthogonal electrical components (I1, Q1; I2, Q2) and are supplied to a multidimensional filter (16). Said multidimensional filter (16) replaces a polarization controller, restores the signal values (I11 + jQ11; I12 + jQ12) that correspond to the signals (QPS1, QPS2) at the transmission end, and compensates signal distortions.
Patent CA-2500757-A1 (CA)
Inventor: HANSEN ANJA LYKKE
IPC: C12N15/10
Filed: 2003-10-08
Abstract: A method for screening a polynucleotide encoding an antimicrobial peptide (AMP) for its antimicrobial activity. The polynucleotide is introduced in a host cell under the control of an inducible promoter. By allowing the host cells, which are sensitive to the AMP, to grow in the absence of AMP before inducer is added, enough host cells will be present to produce enough AMP, instead of the killing or early inhibition of host cells by growing them from the start in the presence of AMP. After the inducer has been added and AMP is expressed in the host cell, the host cell is grown in the presence of indicator cells. Host cells capable of reducing the proliferation of indicator cells are selected. The polynucleotide encoding an AMP is only introduced into a single type of host cells but the AMP activity towards several different indicator cells can be tested without having to introduce the polynucleotide into more than one host cell.
