In a press operable for movements of proof plate exchangeably mounted on an end of a press die into and out of a mold, and wherein the proof plate normally does not exceed a position wherein its topmost portion is at most flush with a topmost portion of the mold during the movements, the improvement includes a drive device independent of the movements for moving the proof plate beyond the topmost portion of the mold, so that the proof plate projects through the mold, and is thereby freely accessible for the purpose of being replaced.

Press with easily exchangeable proof plates

Apparatus for the manufacture of bricks with the aid of a mold normally open on top, ceramic material which may be introduced into the mold, and a piston disposed above the mold which may be moved with respect to the mold, and forms a cover surface of the mold when entering the top of the mold, includes the steps of exerting a non-oscillatory pressure by the piston on the ceramic material, and additionally exerting an oscillatory pressure on the ceramic material.

Vibrating hydraulic press

A method and an apparatus for the manufacture of bricks with the aid of a mold normally open on top, ceramic material which may be introduced into the mold, and a piston disposed above the mold which may be moved with respect to the mold, and forms a cover surface of the mold when entering the top of the mold, includes the steps of exerting a non-oscillatory pressure by the piston on the ceramic material, and additionally exerting an oscillatory pressure on the ceramic material.

Method of producing fireproof bricks

An arrangement for filling an upwardly open cavity of a mold with bulk material includes a feeding receptacle which has an open bottom and is mounted for relative movement along the mold from a receiving position in which bulk material is introduced thereinto, towards a discharging position in which the bulk material is discharged from the feeding receptacle through its open bottom.
