Abstract: A sump pump tracking system includes a pressure sensor including a first port and a second port, a tube extending from the first port, a processor in communication with the pressure sensor, a remote server in communication with the pressure sensor, and a memory in communication with the processor. The memory includes instructions, that when executed by the processor, cause the processor to: receive a water pressure reading from the first port; calculate a corresponding air pressure from the water pressure reading from the first port; and determine the pressure differential between the first port and the second port. The server is configured to be programmed with an alarm threshold limit. The pressure sensor communicates the pressure differentials to the server. The server is configured to compare the pressure differential with the alarm threshold limit and send an alert if the pressure differential is above the alarm threshold limit.

Abstract: An LPG bombe cooling system of a bi-fuel vehicle using both gasoline and LPG is provided. The LPG bombe cooling system is configured to cool the interior of an LPG bombe and to reduce the vapor pressure of LPG by supplying some gasoline from a gasoline tank into the LPG bombe using the fact that the temperature of gasoline in the gasoline tank is lower than the temperature of LPG in the LPG bombe, whereby it is possible to easily refill the LPG bombe with LPG even in the case in which the external temperature is very high, e.g. in the hot season.

Abstract: A configuration for the deck of a marine vessel, wherein parallel and perpendicular travel paths, for movement of individual OBS unit storage baskets, are formed along a deck utilizing, in part, the storage baskets themselves. A portion of the deck is divided into a grid defined by a series of low-to-the-deck perpendicular and parallel rails and each square in the grid is configured to hold an OBS unit storage basket. Around the perimeter of the grid is an external containment wall which has a greater height than the rails. Storage baskets seated within the grid are configured to selectively form internal containment walls. Opposing internal and external containment walls define travel paths along which a storage basket can be moved utilizing a low, overhead gantry. A basket need only be lifted a minimal height above the deck in order to be moved along a path. The containment walls and the deck itself constraining uncontrolled swinging of baskets, even in onerous weather or sea conditions.

Abstract: A shock-proof electric marine engine, e.g. an engine or generator, is for a marine (Navy) ship, and includes a stator and a rotor in a housing. The stator and the rotor are connected in such a way that they are rotatably displaceable in a counter direction and in a radial/axial manner with limited slack. The rotor and stator form a displaceable unit in relation to the housing, which can be displaced away from the housing with a higher vibration overshoot range. The housing is elastically connected to the marine (navy) ship.

The propulsion pod contains an electric motor that is cooled by circulation of a radial airflow within the propulsion pod. The electric motor rotationally drives at least one propeller through a transmission shaft. The absorption device is disposed in the propulsion pod to position and hold the electric motor inside the propulsion pod and also to filter the vibrations emitted by the motor and channel the motor cooling airflow circulation.

Abstract: A vessel comprises a cylindrical hull (10) containing a structure (11) carrying machinery (M) supported from the hull (10) by electromagnetic levitation means (12-17) that maintain electromagnetic forces between flux gaps (24) which are arranged to extend radially of the adjacent hull (10) curvature and longitudinally of the hull (10). In this manner, the transmission of noise from the machinery (M) to the hull (10) is obviated so as to reduce the detectable acoustic signal emitted by the vessel and furthermore, radial expansion or contraction of the hull (10) is prevented from mechanical transmission to the structure (11) via the levitation means (12-17).

Abstract: A propulsion and drive system for a ship includes an engine, a drive train with transmission gear and main clutch, and a propeller shaft. An auxiliary equipment shaft is connected to that drive train via two branches, geared to the drive on opposite sides from the main clutch; and each branch has its own clutch so that only one branch at a time is effective. The branch on the propeller shaft side from the main clutch is effective during high-speed cruising, the other branch during slow speeds, or even during stopping. The auxiliary equipment is to be run at constant speed throughout. Two different examples are the relative location of parts and the coaxial relation among the three clutches involved.
