    • In a process for compacting foundry mold making material, that is loosely heaped in a closed mold space over a pattern, the surface of the material is acted on by a compressed gas with a pressure of at the most 8 bar. This gas is caused to undergo expansion out of an inlet space through a valve in an opening at a gas flow rate of over 50 kg/sec and with a pressure increase rate of over 300 bar/sec, into the mold space. The maximum pressure in the inlet space or antichamber is 20 bar. An apparatus for use in the method is made up of a pressure vessel, a mold flask placed thereunder having a filling frame and a pattern plate. The opening cross section of the valve is 50 to 150% of the horizontal cross section of the mold flask and is opened in a short time of the order of milliseconds.

    • An apparatus for the compaction of foundry mold making material using gas under pressure, comprises a pressure vessel for the such gas, a mold flask, a filling frame, a pattern plate and a pattern thereon onto which the material is to be loosely heaped. The flask, frame and plate form a mold chamber under the pressure vessel and between them there a valve is placed, the valve having a movable valve member adapted to open up a flow cross section of the valve predominantly under the effect of gas under pressure in the pressure vessel. The valve member is guided within the pressure vessel, with the valve member being adapted to perform an opening motion, which at least mainly directed into the mold chamber.

    • In an apparatus for compressing foundry moulding material by pressure gas comprising a pressure vessel for the pressure gas forming an inlet pressure chamber, a moulding chamber positioned below it formed from moulding boxes with sand frames and a pattern plate with pattern on which the moulding material is loosely heaped up prior to compression and a large-area valve arranged between the pressure vessel and the moulding chamber, its closure member frees the valve opening in a few milliseconds, accompanied by the joint action of the pressure in the pressure vessel and thereby moves into the moulding chamber. The closure member is brought into the closed position by a pressure cylinder, whose piston is connected on the stroke side to a high pressure source and with its opposite side forms the movable termination of a gas-pressurized pressure reservoir, the high pressure side outflow being constructed in such a way that the pressure medium flows out at a speed of more than 10 m/s, accompanied by the simultaneous acceleration of the piston under the pressure in the pressure reservoir and the closure member into the open position.

    • To permit greater through-put of a mold box filling and compacting system, mold boxes are moved vertically by a lifting table which passes through the station transport turret (10) to place a pattern or mold carrier plate (11, 12) in the mold box, and, upon continued vertical movement, placing a filling frame (14) about the mold box, and, upon further vertical movement, placing the thus formed subassembly in engagement with a sand filling apparatus (15). Upon subsequent lowering, the subassembly is returned to the turret, the turret rotates and places the subassembly in position for alignment with a compacting station, raises the subassembly to the compacting station for compaction of the sand about the model or pattern. The subassembly is then lowered; after lowering for a short distance, the fill pattern transport, for example another turret or pivotable arm system, is placed in interfering position with the filling frame so that it is stripped off the mold box which is then lowered on a removal conveyor, for removal from the compacting station; continued downward movement at the compacting station table then places the now freed pattern or model carrier plate again on the station transport turret for return to the first position. Sand filling and compaction can be carried out simultaneously on sequentially arriving mold boxes under control of a control system (C) which controls appropriate sequencing.

    • A circuit arrangement for switching PCM channels conducting baseband data signals, with serial data to be switched arriving at n input ports and being converted in blocks to parallel form, intermediately stored in a memory and converted to serial form again after read-out to be fed to n output ports each assigned to one or a plurality of destination addresses. The parallel data blocks are intermediately stored the first time in n input registers assigned to the n input ports. Thereafter, a second intermediate storage takes place in a RAM memory in such a manner that the data blocks are written in successively according to the sequence in which they arrived at a memory address which is counted up sequentially, or the data are subsequently intermediately stored in a RAM memory at a memory address which corresponds to the respective destination address. The data blocks are read out according to the number of the output port contained in the destination address or assigned to the destination address or according to their time position and are again intermediately stored in n output registers which are assigned to the respective n output ports.

    • The molding machine has injection apparatus which operates with compressed air for filling a molding box with molding sand and pre-compacting the sand. Vents for escape of spent air from the molding box are provided in a filling frame, which rests on the molding box during filling and compaction, and may also be provided on the surface of a pattern plate carrier and in a pressure plate against which the sand is finally consolidated by pressure exerted through said carrier. Exhaust means for the spent air comprise an annular passage on the outside of the filling frame. The pressure plate is formed to define nozzles through which the sand is injected into the molding box. Means are described for supplying sand and compressed air, for conveying a succession of molding boxes and for mounting, lifting and lowering the pattern plate carrier and withdrawing the latter for replacement of the pattern.
