Abstract: An arrester for inhibiting hammer caused by interruption of fluid flow in conduits comprises a hollow cylindrical body closed at one end and open at the other. A piston is freely slidable within the body forming with the closed end thereof an hermetically sealed gas chamber. A connector connects the open end of the body with the conduit conveying fluid under pressure. Under fluid hammer conditions, the piston is advanced against the gas in the gas chamber. This forms a cushion which absorbs the shock and prevents the development of fluid hammer.

Abstract: A MANIFOLD ASSEMBLY FOR HOT AND COLD WATER FAUCET PAIRS ARRANGED BACK TO BACK ON OPPOSITE SIDES OF A MULTISTORY BUILDING PARTITON INCLUDES A PAIR OF MANIFOLDS AND INTERCONNECTING CONDUITS. EACH MANIFORLD HAS A CENTRAL CHAMBER WITH PORTS CONNECTING IT TO ONE OF THE HOUSE HOT OR COLD WATER LINES, TO HOT AND COLD WATER FAUCETS ON OPPOSITE SIDES OF THE PARTITION AND TO THE COMPANION MANIFOLD. THE ARRANGEMENT IS SUCH THAT THE HOME LINES PASS UPWARDLY THROUGH THE BUILDING IN A STRAIGHT LINE WITHOUT CROSSING OVER AT EACH BUILDING LEVEL.
