20150260064 | FILTRATION OF GASOLINE DIRECT INJECTION ENGINE EXHAUSTS WITH HONEYCOMB FILTERS - Particulate matter is removed from the exhaust gas of a gasoline direct injection (GDI) engine, by introducing a particulate-containing exhaust gas into an inlet end of a ceramic honeycomb containing multiple axially-extending cells that are defined by intersecting porous walls, passing the exhaust gas through at least one such porous wall to trap the particulate matter in the porous wall, and then discharging the exhaust gas from an outlet end of the ceramic honeycomb. The porous walls of the ceramic honeycomb have a wall thickness of 150 to 750 μm, the honeycomb has an effective permeability of at least 0.8 10-12.?m2? and the ceramic honeycomb contains from 45,000 to 230,000 cells per square meter of cross-sectional area | 09-17-2015 |

20140113511 | POD DRIVE COMPRISING A REDUCTION GEARING - Pod drive which can be fitted to a vessel and which is provided with an electric motor which drives a propeller shaft which is likewise provided in the housing of the pod drive and is connected to a propeller which is situated outside the latter. It is proposed to use a fast-rotating electric motor in combination with a reduction gearing for driving the propeller shaft. The mounting of the propeller shaft is made particularly stable by mounting it on both sides of the electric motor. The reduction gearing may include a planetary system. The electric motor may be fitted next to the hollow propeller shaft. In this case, several electric motors can be arranged around the central propeller shaft. It is also possible to make the rotor of the electric motor hollow and to fit the propeller shaft inside the latter. | 04-24-2014 |
20150158568 | VESSEL WITH ROTATABLE POD - A vessel and a method for driving a vessel. The vessel is provided with a pod arranged at the rear side thereof which is arranged rotatably with respect to the vessel. Rotation is effected about an axis which deviates slightly from the vertical. The axis of the propeller shaft forms an angle which is smaller than 90° with the axis of rotation of the pod. As a result of this combined positioning of the rotation shaft of the pod and the positioning of the propeller shaft, the axis of the propeller shaft with respect to the horizontal will vary when the pod is rotated depending on the rotation position of the pod. This permits optimum adaptation to the various operating conditions of the propeller position. | 06-11-2015 |

20130294720 | SYSTEM AND METHOD FOR MAKING DISTRIBUTED MEASUREMENTS USING FIBER OPTIC CABLE - A method for determining the physical location of a fiber optic channel in a fiber optic cable comprises the steps of a) providing at least one location key having a known physical location, b) establishing the location of the location key with respect to the fiber optic channel, and c) using the location information established in step b) to determine the physical location of the channel. The location key may comprises an acoustic source, a section of fiber optic cable that is acoustically masked, or at least one magnetic field source and step b) comprises using a Lorentz force to establish the location of the magnetic field source with respect to the fiber optic channel. | 11-07-2013 |

20140199017 | FIBER OPTIC CABLE WITH INCREASED DIRECTIONAL SENSITIVITY - A distributed acoustic sensor, comprises a housing having a longitudinal bore therethrough, an optical fiber supported in the bore; and an inertial member supported within the bore, wherein the fiber is mechanically coupled to the inertial member. The inertial member may include a weight and may provides isotropic stiffness such that it deforms more readily in a first direction normal to the bore than it does in a second direction that is normal to both the bore and the first direction. The sensor may include a plurality of axially-spaced centralizers in the bore, and at least one of the inertial member and the centralizers may comprise swellable material. | 07-17-2014 |
