Title: Container store for night safe installation - using container pallets hung on endless chain with automatic loading and unloading interlocked with indexing feed
Inventor: BIALOGLOWICZ EDWARD
IPC: E05G7/00
Filed: 1975-05-02
Abstract: A continuous chain drive with a large number of carriers for containers provides a ready store for use with night safe installations. The carriers (20) are supported between two chains (34) in the form of a continuous loop.

Title: Pressure wave damper for liquid metal reactor circuit - is gas-filled closed vessel containing liquid throttle
Inventor: DUMM KONRAD ING GRAD
IPC: F16K17/40
Filed: 1975-07-25
Abstract: A pressure wave damper for a liquid metal plant, esp. liq. metal cooled reactor, consists of vessels attached to a liq. metal line by a bursting disc, which normally prevents ingress of the liq. metal into the vessel. Each vessel is fully closed a throttle, esp. a vertical cylinder, which does not come into action until the liq. metal has partially filled the vessel. Preferably, an increasing throttling action is produced as the liq. level rises, esp. by additional holes, distributed through the height of the cylinder. Used for primary and secondary liq. metal circuits of a reactor. The vessel is filled with inert gas (not claimed) so that the initial shock wave which bursts the disc is damped. As the liq. rises and flows through the holes in the throttle, the reflected shock waves caused by re-expansion of the compressed inert gas are also damped. The inert gas pressure balances the normal operating pressure, so that the bursting disc is not heavily loaded. There is no venting to atmosphere.

Title: Power utilisation in appts. for regenerating plastics waste - which is improved by keeping drive motor current constant at maximum rated value
Inventor: BECK ERICH
IPC: B29B17/04
Filed: 1975-10-10
Abstract: Appts. of parent patent is for regenerating dirty plastic waste, esp. plastic film, by washing, disintegrating, agglomerating and granulating the waste in a single vessel. At the bottom of vessel there is at least one beater tool driven by an electrical machine is rotatably mounted. In the addition, the electrical power of the drive machine can be regulated during the whole regenerating process, at a more or less constant value by changing the machine speed and/or the flow resistance between the beater tool and the material filling the vessel, as a function of the load current of the machine. The electrical power of the drive machines is pref. adjustable to the nominal power rating. By better utilisation of the motor power during the regeneration, a smaller and cheaper motor can be used for the same with load than in the normal case where the motor current is not regulated.
