Novel precast concrete boxes are disclosed which can be assembled together and/or with structural shapes disclosed in U.S. Pat. Nos. 5,697,736 and 6,491,473 to form waterfront structures such as seawalls, boathouses and the like. Novel methods of waterborne transport and installation of the boxes are disclosed, including modular vessels having bow and stern sections which can be connected directly together or mounted to a mid-section containing assemblies of concrete boxes, other structural elements or other vessels such as floating drydocks. Modular vessels can be assembled with any or all of the bow, midship and stern sections comprising honeycomb arrays of vertically-oriented hexagonal boxes.

Novel precast concrete boxes are disclosed which can be assembled together and/or with structural shapes disclosed in U.S. Pat. No. 5,697,736 to form waterfront structures such as seawalls, boathouses and the like. The boxes can be sized and proportioned so as to be conveniently assembled in such structures and to be easily transported via intermodal transportation media. Novel methods of waterborne transport and installation of the boxes are disclosed. Shellfish habitats based upon the boxes are also disclosed.

An electronic controller is provided for controlling operation of the engine and/or transmission in a marine propulsion system without use of mechanical linkages. A control allows for setting a desired engine speed signal and a signal link allows for electromagnetically transmitting the desired engine speed signal from the control to the controller. A module allows for supplying to the engine, based on a received signal indicative of actual engine speed and the desired engine speed signal, an engine control signal for adjusting engine speed.
摘要:
An apparatus having a variety of applications is provided for indexing a rotary component. The apparatus of the present invention includes a housing, a resilient electrically conductive band contained within the housing and connected to the rotary component, at least two indexing electrical contacts located on the housing internal periphery and is slidable contact with the band, and a bridging electrical contact electrically connected to the band while the band rotates. The band exerts a biasing force on the housing, thereby mainaining band contact with the housing internal periphery, while also causing a point of separation of the band from the housing. Drive means is provided for rotating the band within the housing. Finally, electrical circuit means, including electrical supply means and switching means, are provided for selecting one indexing contact and applying power through the drive means to rotate the band and the rotary component until the band disengages from the selected indexing contact, thus halting further movement of the band and rotary component.

An apparatus is provided for electrically indexing a rotary component. It includes a housing, a resilient, electrically conductive band contained within the housing and connected to the rotary component, at least two indexing electrical contacts located on the housing internal periphery and in slidable contact with the band, and a bridging electrical contact in connection with the band. The band exerts a biasing force on the housing, thereby maintaining band contact with the housing internal periphery, while also causing a point of separation of the band from the housing. Electrical circuitry is also provided so that once an indexing contact has been selected, the band and the rotary component can be rotated until the band disengages from the selected indexing contact, thus halting further movement of the band and the rotary component.
