Title: Treatment of waste soln. contg. ammonium nitrate - originating from prepn. of nuclear combustible material, by thermal decomposition of the ammonium nitrate
Inventor: MUELLER BURKHARDT DIPL ING
IPC: G21F9/06
Filed: 1978-11-11
Abstract: The treatment of waste solns. contg. ammonium nitrate and possibly urea, originating from the prodn. of combustible and/or fertile materials for nuclear reactors, involves injecting the relatively conc. soln. as a fine spray, into a zone of thermal decompsn. of ammonium nitrate. The decompsn prods. are sepd. by condensn. into a liq. phase and a gaseous phase. In this process, the waste soln. is first concd. in a thin film evaporator equipped with a vacuum pump. The concentrate then passes through a filtration apparatus and is fed into a cooled storage reservoir, from which it is introduced into a heated decompsn. tube. The decompsn. prods. pass through a condenser, and the condensate is collected in a reservoir. The process can be carried out continuously, and allows relatively conc. solns. to be treated without risk of explosion.

Title: Fluid oscillation damping membrane - comprises pleated surface spring-loaded to allow passage of fluid around edge when moving
Inventor: FREY GUENTER
IPC: F16L55/05
Filed: 1978-11-17
Abstract: The membrane to absorb fluid oscillations is spring loaded and is at right angles to the flow. The fluid flows round its outside edge radially as the membrane vibrates against the spring under the action of the fluid. When there is no flow, the membrane seats at its outer rim firmly against a strike surface so as to prevent access until the fluid is returned. The membrane changes position relative its spring to increase the flow section upstream. The spring loads the membrane centrally, the membrane being crimped or pleated at the rim to increase its elasticity. Where the membrane serves as a fuel injection filter in conjunction with a cylindrical filter cartridge, it clips between cartridge and end wall of the housing.
