    Abstract: A device for effecting secondary circulation of water into a hot water tank not having a return opening. The arms of a T-fitting are place in series with the distribution line near the outlet port of the water tank. A return line, continuous at one end with the distal portion of the distribution line, is continuous at the other end with a relatively small internal line which lies within the leg of the T-fitting, one arm of the T-fitting, and extending through the outlet port into the water tank. A relatively low power pump and a sinking-ball valve are placed in series with the return line to cause the flow of water in the secondary circulation system to flow in one direction only.

    Abstract: In a hot water distribution system, a priming device installed just ahead of a tap stores a small amount of water and continuously maintains it to the temperature of the hot water source. When the tap is opened, the water from the priming device is first drawn while the cooled down water which was stationary in the pipe coming from the heating tank refills the priming device. When the pipe is cleared of cold water the priming device is bypassed, and its stored cold water is slowly admixed in the flow of hot water to the tap.

    Abstract: A centrifugal circulation pump for a fluid heat carrier where the pump has a housing including a centrifugal impeller, an inlet pipe for admitting a first heat carrier into the housing and a discharge pipe for discharging the first heat carrier from the housing. A heat transfer means in the form of a tubular coil is positioned in the housing through which a second heat carrier flows. The centrifugal impeller moves the first heat carrier with a swirl motion in a direction parallel to the turns of the coil whereby heat is exchanged between the first and second heat carriers.

    Abstract: A step bearing with spherical gliding surfaces having a stationary mounted ceramic ball mounted on a strut, on which a magnetic rotor with a concave cap is rotating under working conditions. During operation the rotor with the cap is pressed by magnetic thrust in the direction toward the strut, while a second annular bearing member of the rotor prevents axial movement of the cap when axial forces in the direction opposite to the direction of the magnetic forces become higher than the magnetic forces.

    Abstract: A heating system including a hollow body having a part of a low pressure and low temperature heating circuit therein. The hollow body has a plurality of parallel juxtaposed fluid channels formed by a pair of spaced thermoplastic wall members connected by webs to form the channels. A plurality of the channels are connected to an inlet manifold and to an outlet manifold whereby the flow of fluid in said channels is parallel over substantially the complete area of the wall members.
