Abstract: A system for preventing over pressure in a flexible tank when connected to a water grid that includes the flexible tank and a control unit. An inlet of the tank is connected to the water grid through the control unit. The control unit includes a closed box, an inlet that is connected to the water grid, an outlet that is connected to the inlet of the tank, and a float valve. The user place the flexible tank and set the float so that it will be opened or closed in a certain height of activating water level in the control unit and to place the control unit in a way that the activating water level is at the same level of a desired water level of the flexible tank.

Abstract: A system for hot and cold water supply to consumers that includes photovoltaic solar panel, wind turbine, water heating tank, water tank and cooling system. The heating tank includes an electrical connection mechanism, an outer layer, a water bag and heating carpet that is positioned in a dry space between them. The water tank includes an outer layer and a water bag. The electrical connection mechanism connects the heating carpet and the cooling system to the photovoltaic solar panel and to the wind turbine. The volume of the heating tank or the water tank are larger than the volume of the average hourly hot or cold water consumption of the consumer. The system is able to supply hot and cold water also at times that the photovoltaic solar panel and the wind turbine do not produce electricity.

Abstract: A standalone adjustable transportation system that is designed to be positioned on a platform of a vehicle that consists of a cargo carrier basket that consists of a basket with four connecting means that each one of them includes a locking means, a frame that consists of four horizontal rods that each one of them includes a locking means that corresponds with the locking means of the connecting means, and four adjustable legs that each one of them has a trailer jack that is designed to control a length of the adjustable leg to which it is assembled, and by that to enable a user to control separately a precise length of each one of the adjustable legs.

Abstract: The present invention provides electric cable having substantial immunity to external magnetic fields. The cables may be prepared by splitting one or more conductors of an original cable design into two or more sub-conductors, determining a crosssectional area for each one of the sub-conductors to obtain a desirable electrical current density therethrough, arranging the sub-conductors in said cable in an intervening fashion such that each sub-conductor is placed adjacent and alongside at least one neighboring conductor or sub-conductor associated with either a different electrical phase or electric current direction, and electrically connecting the sub-conductors of each split conductor in parallel.

Abstract: A standalone adjustable transportation system, which is designed to be positioned on any standard vehicle with a platform, that includes a cargo carrier basket, a frame, adjustable legs, and trailer jacks. The frame is designed to connect the adjustable legs to the cargo carrier basket. The jack trailers are assembled to the adjustable legs, and each trailer jack controls each adjustable leg. By that enabling to convert any vehicle with a platform to a vehicle that can transport a cargo carrier basket that may include a cargo, to place the cargo carrier basket on the ground and to release the vehicle.

Abstract: A flexible and inflatable tank for the supply of potable water that is made of a strong, rigid and flexible material and is designed to incorporate a thin, flexible inner bag that is made of materials that comply with standards for the storage of potable water. The tank is made of a rectangular sheet, a pair of walls, and one or more openings and is shaped in general like a closed, round, oblate cylinder with two side walls.

Abstract: An adjustable transportation system designed to be positioned on a trailer or on a vehicle that includes a hammock-like structure, a frame, adjustable legs, and jacking means. The hammock-like structure is attached to the frame, as are the adjustable legs. The bottoms of said adjustable legs are equipped with jacking means.

Abstract: A bus-bar system usable for electrical cabinets for distributing electrical power supplied by an electrical supply cable comprising two or more electrically conducting wires. In some embodiments the bus-bar system comprises a predetermined number of bus-bar elements each electrically connectable to at least one of the wires of the electrical supply cable. At least one of the bus-bar elements may be formed by a group of at least two sub-bus-bar elements electrically connectable to each other in parallel. Each group of the sub-bus-bar elements may be electrically connectable to at least one of the wires of the electrical supply cable, where each of said bus-bar and sub-bus-bar elements being located adjacent at least one other bus-bar or sub-bus-bar element associated with either different electrical phase or different electrical current direction to thereby cause magnetic fields emanating from said bus-bar and sub-bus-bar elements to destructively interfere with each other.

Abstract: Disclosed herein are electrical power distribution units designed to substantially reduce the magnetic fields emanating from the power distribution units by using two or more bus bar elements for each electric carrying element of the bus system, and positioning each bus bar element in parallel and adjacent at least one other bus bar element carrying a different electrical phase or current direction. Various arrangements of bus bar elements are also disclosed, as well as methods of modifying conventional power distribution units to provide such bus bar arrangements of the invention, that substantially reduce the magnetic fields emanating from the bus bar systems of the units.
