Abstract: A water supply system includes a main water tank that is configured to store water and includes a heater to heat the stored water to close to but below a boiling temperature thereof, to provide main heated water. A dispenser water tank receives a portion of the main heated water, and is free of any heating elements to add heat to the water stored therein, and providing dispensable heated water. A water mixer includes a first pipe for receiving the dispensable heated water from the dispenser tank and a second pipe for receiving utility water from a faucet that supplies utility-provided water, with a mixing chamber from which the waters from the first pipe and the second pipe are dispensed and/or in which these waters are admixed.

Abstract: A wheeling apparatus for a suitcase has a wheeling frame defining a frame plane. A wheeling leg assembly pivotably is attached to the wheeling frame at a pivoting axis and is pivotably moveable between a first position adjacent and parallel to the wheeling frame plane and a second position extending at an adjustable angle to the wheeling frame plane. Leaning wheels are secured to the wheeling leg assembly. Straps enable the apparatus to be removably secured to the suitcase. A flexible wire having a first end attached to the wheeling leg assembly and a second end attachable to a holding device that is configured to firmly hold the second end at an adjustable location thereon and which is so configured as to allow a user to selectively adjust an inclination angle at which the wheeling leg assembly extends relative to the frame plane during use of the apparatus.

Abstract: A game set allows building wall structures with magnetic tiles that have magnets located around the peripheral sides or edges. Since the tiles are held only by magnetic force, they are susceptible to buckling by application of perpendicular forces and to prevent such buckling, a plurality of thin holding strips are provided that extend over the joint, magnetically held edges of the magnetic tiles and prevents buckling. The magnet set also includes additional accessories, such as figurines that can be magnetically adhered to the wall structures, electrical lighting that can be adhered to the wall structures and drawing sheets that can be adhered to the wall structures.

Abstract: An electrical vehicle including a vehicle body, a passenger compartment, a chassis supporting the passenger compartment, a plurality of wheels and at least one electrical motor for driving the wheels. A battery compartment of the vehicle is configured to removably mount therein a plurality of more than two rechargeable batteries which are movable into position in the battery compartment by a battery conveyor system which has a battery access opening through which batteries are installed or removed, one by one, to and from the battery compartment. In the battery compartment, a connection mechanism effects the needed mechanical and electrical connections. An overall control system controls the conveyor system and the connection mechanism to enable rapid replacement of the removable batteries, whereby an electrical vehicle can be instantly driven, even after its batteries have been discharged by a replacement of the discharged batteries and the installation of freshly charged batteries.

Abstract: A wheeling frame for a suitcase which has its own rolling wheels includes a frame supporting a pair of leaning wheels arranged at ends of a pair of pivotable legs, with a first wheel arranged at the end of a first leg and a second wheel arranged at the end of a second leg. The leg positions are adjustable between a stowed position and a deployed, adjustable position extending at an angle to the frame. The legs have a movable pivoting axis and adjustable lengths. A handle system at a proximal end of the frame is adjustable in length and angle, and is operable in conjunction with the leaning wheels to roll the suitcase in a stable leaning position, to allow walking the suitcase on steps of a staircase, and to be converted into a suitcase table, to ease packing and unpacking.

Abstract: A universal charging accessory for mobile devices. The accessory has a generally flat and thin body configured to lie flat against the flat rear side of the mobile device and includes an internal rechargeable battery, two charging plugs that are configured to be electronically coupled to the charging plug of the mobile device, with the charging plugs being retrievably stowed inside the body of the accessory and to be withdrawn as needed to charge the mobile device. The accessory has a window formed in the body of the charging accessory which receives, interchangeably, a plug-in module that can be inserted into an AC socket to charge the internal battery as well as the cellphone battery.
