Title: Continuously acting press for mfr. of composite material - having pressure bars longitudinally movable sequentially to effect pressing
Inventor: CAUGHEY ROBERT ADAMS
IPC: B30B9/28
Filed: 1975-09-12
Abstract: A press for the mfr. of flat composite board includes a pair of relatively reciprocable platens (10,14) on which are mounted a series of pressure bars (1-8) movable individually longitudinally along the platens. In use the platens are permanently in the pressure applying position and the bars are moved one by one from a position at the exit end of the press to a position at the feed end. When all the bars are located at the feed end the bars are moved in unison back to the exit end and this cycle is repeated. During movement of individual bars to the feed end the friction of the remaining bars is sufficient to prevent movement of the board but the concerted movement of the bars to the exit end causes a length of board to be drawn through the press.

Title: Removing radioactive wastes from nuclear power station - using addn. of binder to effect solidification after filling into containers (SW181076)
Inventor: BAATZ HENNING DR
IPC: G21F9/00
Filed: 1975-10-04
Abstract: A process for removing radio-active wastes from a nuclear power station consists of filling them into containers, adding a binder capable of solidifying them and transporting the containers with the solidified wastes, immediately to the place where they are finally deposited. The containers in or near the station are handled, and the binder is added, under a shield. A plant for carrying out the process incorporates containers, each with a cover in which is an agitator, an outlet for gases and an inlet for binder, a vent gas purificn. system and a unit for prepg. and adding the binder. The many costly and dangerous operations performed at present are no longer necessary. The risk to the environment is considerably reduced. Filling and binder addn. can be carried out so that no radioactive substances can escape from the containers. The vol. of integrated wastes resulting from the radioactive wastes and the binder is considerably reduced.
