Title: Double-acting forging press using only one crank - esp suitable for forging impeller wheels of centrifugal pumps
IPC: B21J7/34
Filed: 1973-06-20
Abstract: The machine has a housing with a press. vessel filled with oil and a piston which operates the lower anvil; a floating piston-rod links the piston to the crankshaft and, as the stroke of the glide-member of the piston is greater than the stroke of the piston the forging blows are not transferred to the crankshaft. The press. vessel contains four further pistons arranged symmetrically round the main piston, in chambers filled with nitrogen; the four piston rods project through seals in the base of the oil-chamber and are mounted on a cross-plate which is linked by four pillars outside the housing to an upper traverse holding the upper anvil or punch. As the crankshaft rotates, the nitrogen expands, pushing the cross-plate (and hence the upper forging tool) downwards; simultaneously, the entry of the four pistons into the oil chamber drives the main piston upwards so the two anvils, or forging tools come together.

Title: Prodn of potable water from river water - by biological elimination of ammoniacal nitrogen by nitrifying bacteria
IPC: C02F3/06
Filed: 1974-08-06
Abstract: River water is treated for the prodn. of potable water by process involving the biological elimination of the ammoniacal nitrogen. The oxidn. of these impurities is effected by the intervention of bacteria contained in the water and accumulated in a certain vol. of the sludge in a coalescence tank. This is situated in the downstream zone of the flocculation compartments preceding a settling tank. The sludge is recycled from the base of the coalescence tank to the inlet of the raw water and serves to support the nitrifying bacteria and so assures the biological nitrification of the impurities contg. ammoniacal nitrogen. Apart from the action of the nitrifying bacteria, biological oxidn. results from the presence of oxygen in the water to be treated; if this is not sufficient an addition can be made downstream of the flocculation compartments. Because of the recirculation of the sludge without interruption, an appreciable improvement results in the efficiency of the elimination of the ammoniacal nitrogen.

Abstract: An instrument for liquid velocity or flow measurement determines the anisotropy of acoustic wave propagation. It has two transducers inserted in opposite sides of a conduit carrying the liquid. The two transducers are aligned along a direction at an angle with the liquid velocity vector and they are facing each other. Each transducer can send toward the other and receive from the other ultrasonic quasi-plane surface waves. The instrument also has means for simultaneous excitation of the transducers by a series of recurring pulses modulating a high frequency carrier. It also has means for measuring the duration of the ultrasonic signal travelling between the two transducers. The difference in duration between two signals, the square of their sum and the ratio between these quantities are used to obtain a measure of velocity and flow.
