Abstract: There is provided mechanisms for controlling movement of a propeller shaft on a vessel. A controller includes processing circuitry. The processing circuitry is configured to cause the controller to detect movement of the propeller shaft by determining a signature of a sustained oscillation of the propeller shaft. The processing circuitry is configured to cause the controller to control movement of the propeller shaft according to the determined signature.

Abstract: A method of controlling power transfer in a power system including a main bus, having a first and second bus sections, the first bus section connectable to the second bus section, first and second power generating units connectable to the first and second bus sections, a first and second drive systems connectable to the first and second bus sections, a central energy storage system, and a control system. The first and second drive systems include first and second bi-directional power converters connectable to the central energy storage system, and wherein the control system is arranged to control the first bi-directional power converter to transfer power from the first drive system to the central energy storage system, and to control the second bi-directional power converter to transfer power from the central energy storage system to the second drive system.

Abstract: A board game and method of play for a game which involves rapid paced action, chance and attention to detail. The board includes a plurality of game cards on a game board having a matrix of number with letters as column headings. Players purchase cards (locations on the board) and have a hand held duplicate for markup. In addition to game cards, players can purchase select special number sequences to win. The game is accelerated by providing a numerical designator adjacent or on the card which is the winning combination of numbers so that the player can see the combination without looking to the matrix of number on card.

Abstract: The invention relates to a polishing tool with improved handling characteristics, which produces better working results. Said tool comprises a solid polishing body (1), substantially consisting of felt, said body having numerous subdivisions (1).

Abstract: The invention relates to a plated grinding tool which is symmetrically configured around an axis of rotation. Said plated grinding tool comprises a plurality of grinding plates arranged on the periphery and/or on the faces, and comprises a support body on which said grinding plates are fixed. The plated grinding tool also comprises a device for connecting the plated grinding tool to a drive device. The support body has at least one rotationally symmetric lateral surface on which the grinding plates are at least partially fixed. According to the invention, the support body comprises at least one central element which is configured as a disc and which extends in an essentially radial manner in relation to the axis of rotation. In addition, the device for connecting the plated grinding tool to a drive device has a locating face, said face being formed by the disc, which is provided for connecting the plated grinding tool to a drive device.

Abstract: The apparatus includes an elongated buck having an upper convex surface which supports the seam with the edges thereof outboard, and a portable iron having a concave bottom surface and a pointed nose which cooperates with the convex buck to simultaneously open and press the seam sandwiched therebetween as the iron moves in a forward direction thereover. The bottom edge of the iron is recessed on either side of the nose to permit the opened edges of the seam forward of the nose to flow smoothly beneath the iron as the iron advances thereover, preventing bunching of the seam forward of the iron as it advances. A jet of steam directed downwardly and forwardly is emitted from the nose of the iron to moisten the opened seamed edges and thereby enhance the permanency of the overbusting operation.
