Abstract: An outboard motor is provided with an internally contained cylinder and moveable piston. The piston is caused to move by changes in differential pressure between first and second cavities within the cylinder. By adding a hydraulic pump and a steering valve, the hydraulic steering system described in U.S. Pat. No. 6,402,577 is converted to a power hydraulic steering system by adding a hydraulic pump and a steering valve to a manual hydraulic steering system.

Abstract: The present invention includes a propshaft assembly that has a propshaft connected to a transmission and an axle and a center support that attaches the propshaft to a vehicle. The center support permits the propshaft to move vertically during operation of the vehicle. The present invention also includes a method for damping the natural bending resonance of a propshaft where the propshaft is connected to the underbody of a vehicle with a center support. The center support may be adapted to permit the propshaft to move vertically in response to vertical movement of an axle attached to the propshaft. Alternately, the center support may be adapted to selectively fix the vertical position of the propshaft when the propshaft is approaching its natural bending resonance frequency.

Abstract: A device (1) is provided for horizontal resetting to center for a central buffer coupling arranged pivotably by a coupling shaft (2) on a rail-borne vehicle. The device has a guide (3) following the pivoting movement of the coupling shaft (2) around its vertical pivot axis. The device has pressing surfaces (4) provided symmetrically to the longitudinal axis of the coupling shaft (2), and has a pressing device (7), with parts supported against an articulated housing (5) for the coupling shaft and bringing about the horizontal resetting to center. The pressing device acts permanently or switches off or can be switched off depending on the pivot angle or can be actuated by a pneumatically, hydraulically or electrically operated actuating device. To facilitate especially the coupling in tight curves or to make it possible in the first place, the actuating device is designed as a remote-controllable adjusting drive (11).

Abstract: The invention is directed to a thick stator vane that effects continuous acceleration of the water stream within the jet pump, a non-uniform spacing of stator vanes or impeller blades to reduce noise output of the jet pump during operation, and a coupling structure positioned between the impeller and engine that prevents transfer of axial thrust to the engine caused by jet pump failure.

Abstract: A device controlling the depth and motion of an object underwater by using a processor to accurately control the volume of gas within, and thereby the buoyancy, depth, and motion (rate of ascent and descent) of, a buoyancy chamber that is attached to the object. The device has a central component incorporating a processor and associated memory, the processor being in communication with: a buoyancy chamber and a means for measuring the volume or level of gas within, at least one gas control mechanism(s) to input and remove gas from the buoyancy chamber; a depth measuring sensor, a power source; a gas source, and an input device to instruct the processor. By manipulating the volume of gas within the buoyancy chamber, using the gas source and the at least one gas control mechanism(s), the processor is able to control the rate of ascent, rate of descent, level of buoyancy, and depth of itself and the object to which it is attached.

Abstract: The invention concerns an arrangement of service positions for maintenance apparatus, which can travel on a guide rail along a multiplicity of similar workstations on a first side of a textile machine, wherein a maintenance apparatus in a first service position at the elevation of a machine framing of the textile machine can be pivoted away from, or transversely withdrawn from the guide rail. Per side of the textile machine, at least two maintenance apparatuses are exclusively assigned thereto, whereby the guide rail on the first side, at least at one end of the textile machine, is elongated beyond the textile machine and a second service position is placed on the elongated guide rail. In this way, it becomes possible, with a large number of workstations to assure the shortest possible duration of a standstill, wherein in the case of a failure or preventive unkeep of one maintenance apparatus, another maintenance apparatus can serve a workstation in a short time.

Abstract: A grip pad assembly (10) including an outer pad member (12) having an upper surface defining a non-slip surface and an insert (18) within the pad member (12) having on its upper surface, a hook and loop material (20) and a central ridge (22). The pad assembly (10) may be used on a surfboard, or other watercraft, or in any other application where enhanced grip is required, in combination with an article of footwear (40). The article of footwear (40) comprises a first retaining portion (45, 46) adapted to extend over and be secured to the foot of a user, a second retaining portion (43, 44) adapted to extend over and be secured to the ankle of the user and a complementary hook and loop fastener (47) on its undersurface. The footwear may have a means (51) for securing a leg rope for connection to the surfboard.

Abstract: A mounting support (100, 200) for a marine vessel inboard drive propulsion system used in connection with a precision driveline includes a substantially cylindrical housing (107), one or more bearing assemblies (113) positioned within the cylindrical housing (107) for promoting rotation of a drive shaft (103) and one or more seals (119) typically located at both ends of the housing (107) for preventing water from contacting one or more of the bearing assemblies (113).

Abstract: A boat propeller safety enclosure for the covering of the propeller of a boat during road transportation, which enhances the ability of those following the trailered boat to avoid contact with the propeller, is provided. This enclosure has a cinchable opening for ease of attachment and removal and for tightly fitting about a propeller. A reflective and/or brightly colored surface is provided.

Abstract: A mounting device for vertically positionally adjusting an outboard motor relative to a boat transom, the mounting device comprising at least one bracket connected to a transom, at least one support member pivotally connected to the bracket at one end and connected to an outboard motor at the other end wherein the motor is vertically positionally adjustable relative to the transom upon pivotal movement of the support member. A jack member controls the pivotal movement of the support member and comprises telescoping inner and outer tubes wherein the inner tube is connected to the transom and the outer tube is connected to the support member wherein telescopic movement of the outer tube relative to the inner tube pivots the support member to vertically positionally adjust the motor relative to the boat transom.

Abstract: A deviating device for deviating a transporting means in a deviating plane was a deviating unit, two track portions of a movement path of a transporting means adjoining the deviating device and clamping the deviating plane, and mountable on the deviating unit, the track portions being mountable on a separate component of the deviating device, the components being turnable relative to one another about a turning axis which is substantially orthogonal to the deviating plane and being fixable in a predetermined angular position.

Abstract: A ship includes a ship's hull which is intended for accommodating cargo and/or people, and at least one rotatable steering propeller as a propulsion unit. The rotatable steering propeller is arranged in a connection unit in the form of a box in the stem of the ship's hull. Electrical and mechanical components for supplying power to and controlling the steering propeller and its electric motor are at least partially combined in functional modules which are in the form of a transport container. The container is designed such that it can be functionally tested, can be accepted at its point of manufacture, and can be installed in this form at any desired location in the ship based upon the container base structure.

Each sideframe comprises an elongated top compression member, two diagonal compression members extending generally downwardly at acute angles from near the ends of the top compression member, and a bottom member joining the other ends of the diagonal tension members. Two column members also extend vertically between the bottom member and the top compression member. Such column members are strengthened by two ribs that extend laterally across the structure of the column member between sidewalls of the column member.
