The primary magazine includes a number of shell holding canisters pivotally mounted to a canister carrier rotatably mounted on a core. A Geneva drive incrementally rotating the carrier and canisters to sequentially position the canisters in a p...

A fluid flow machine consisting of a stator, mounted underneath a hot water tank, and an armature-impeller unit arranged inside said hot water tank, being separated from said stator by a spherical, magnetically permeable separation wall, which generates a toroidal vortex inside the water tank. Said vortex conveys hot water from the upper region of the tank to its lower region until the whole tank is filled with water of a uniform temperature.

A hot water tank particularly for a beverage brewing apparatus of the infusion type in which the hot water tank has a water draw-off tap at a position between the top and bottom of the tank and a thermostat above the outlet in the tank to the tap and a control means connected to the thermostat such that water may only be drawn off through the tap when the temperature of water above the tap outlet is at least as high as a predetermined temperature. The controller ensures that the user cannot draw...

A hydration tank provided with an interior rotating vessel located between a stationary wall of the hydration tank and a stationary wall of a central inlet tube provided centrally within the tank. Liquid flows downward into the tank via a central inlet tube, then upward between the inlet tube and the rotating vessel, and then again downward between the rotating vessel and the tank wall to the exit. Horizontal vanes are provided on both the inside and outside of the rotating vessel that interleaf...

This device provides for measuring the particulate content in a fluid storage tank. A sample of fluid is taken from a fluid storage tank; and compared to a field visual reference chart. Using this chart results in identifying tanks containing a maximum or average particulate allowable.

An aboveground fueling facility includes one or more vertical fuel supply tanks, each of which is positioned on a reinforced mounting pad on a fueling island that also includes one or more fuel dispensers. Fuel is supplied from the vertical fuel supply tanks to the dispensers via piping that is secondarily contained within the reinforced mounting pad. Each of the vertical fuel supply tanks may have more than one compartment so as to permit different grades of fuel to be dispensed by the dispense...

The invention provides for a skimmer (10) interconnected to the floating roof (30) of a floating roof tank (300) wherein a mixture of at least two immiscible liquids, including a lowest specific gravity liquid (50) and at least one higher specific gravity liquid (40), are stored. The skimmer (10) of the present invention is placed on the underside (20) of the floating roof (30). A funnel (140) is attached to the underside (20) of the roof (30) to extend downwardly into the liquid mixture wherein...

Liquid is circulated from bottom to top in a pressure tank by means of a gas pump including an upstanding pipe located within the tank and up through which gas is pumped at a pressure exceeding tank pressure to carry liquid which enters the pipe at the bottom up to the top of the tank.

A portable removable sludge cleaner for tanks is provided in two sections, one of which rests on top of the tank and has a travelling bridge from which is suspended the second section. This second section is a suction head carrying frame unit deposited into one end of the tank with the aid of a crane or overhead pulley. The travelling bridge section is then deposited on top of the tank by the crane or pulley. The bridge is centered for balance during the mounting operation and after depositing o...

A device for a fuel tank for a car with a main fuel tank, comprising a filling tube, a ventilation box, and a piping system leading from the filling tube to the main tank. A reserve tank permanently built into the car is located within the piping system. The reserve tank has an upper wall and a wall with an opening therein. The reserve tank communicates with the filling tube. A pipe protrudes into the reserve tank and has at one end an upwardly open rim, whereby the height of the upper rim deter...
