Abstract: The invention relates to a method for operating a high-voltage pulse system (1), preferably a system (1) for the fragmenting and/or weakening of material (2) by means of high-voltage discharges, with an energy store (3) for providing the energy for the high-voltage pulses and a charging device (4) for charging the energy store (3). According to the method, in the intended high-voltage pulse operation, a sequence of high-voltage pulses is generated with the system (1) and thereby the energy store (3) is discharged completely at each high-voltage pulse and is only after the expiry of a charging pause (LP) recharged again for the next high-voltage pulse by means of supplying charging energy with the charging device (4). By means of the operating method according to the invention, a time window is created between two successive high-voltage pulses each, in which the energy store(s) are substantially completely discharged and no charging-voltage is applied.

Abstract: A bending machine with a bending information display apparatus has a machine frame, a longitudinally extended, fixed machine table, and a longitudinally extended press beam. The longitudinal expanse and the press beam movement direction define a working plane. An insertion plane essentially normal to the working plane is defined by an upper machine table flat side or a lower tool disposed thereon. The working plane establishes a front working and manipulation space and a closed rear machine space. A projector disposed above the insertion plane in the rear machine space has a light beam path directed away from the insertion plane. A reflector disposed in the working and manipulation space has a first reflective surface pivotable by an angle to the horizontal so that a light beam incident from the projector beam path leaves the first reflective surface as a departing light beam toward the insertion plane.

Abstract: Disclosed is a method for forming a tube with high internal pressure and low external pressure. The method comprises: putting a tube to be formed into a cavity, such that a bulging area (15) is formed between the tube to be formed and an inner wall of the cavity; continuously injecting a low-pressure fluid into the bulging area, and then injecting a high-pressure fluid into the interior of the tube to be formed, the high-pressure fluid creating a pressure on an outer wall of the tube to be formed such that the tube to be formed starts to expand to the bulging area; stopping the supply of the low-pressure fluid when the tube is bulged to conform to the inner wall of the cavity; and taking the formed tube out to complete a working cycle. Further disclosed is a forming machine for forming a tube according to the above method.

Abstract: A pin mill includes a rotor plate mounted on a shaft and having concentrically spaced-apart circular arrays of pins arise from an end face. The rotor pins interdigitate with complementary concentric arrays of pins arising from a face of a stator mounted on a door. The door swings open on a hinge mounted on two translator pins so that the door can translate the interdigitated pins before swinging open so that the pins arrays do not collide with each other while the door is opening. The rotor operates within a cylindrical screen which retains particles being broken up until they are small enough to exit. The rotor also includes a circular array of vane knives which sweep closely within the screen and also entrain cooling air into the macerating volume of the mill. Oversized particles trapped in the screen also get cleared and split apart by the passing vane knives.
