Abstract:
Die Erfindung betrifft ein Verfahren zur Sanierung und Aufbereitung von Abbruchmaterial, das mineralische und asbesthaltige Bestandteile enthält. Das Verfahren weist dazu die folgenden Schritte auf: Aufbrechen des Abbruchmaterials, um die mineralischen und asbesthaltigen Bestandteile zu zerteilen; Trocken- oder Nassklassieren des aufgebrochenen Abbruchmaterials, um dieses mindestens in eine Feinfraktion und eine Mittelfraktion zu trennen; Nasssortieren der Mittelfraktion, um diese in eine Schwerfraktion, eine Leichtfraktion und asbesthaltigen Schlamm zu trennen, wobei entweder die Schwerfraktion asbestfrei mineralisch und die Leichtfraktion asbesthaltig oder die Schwerfraktion asbesthaltig und die Leichtfraktion asbestfrei mineralisch sind. Ein weiterer Aspekt der Erfindung betrifft ein System zur Sanierung und Aufbereitung von Abbruchmaterial, das mineralische und asbesthaltige Bestandteile enthält.

730,051. Cutting glass. PILKINGTON BROS., Ltd., and DENLOW, P. M. Nov. 13, 1953 [Nov. 14, 1952], No. 28830/52. Class 56. Glass ribbon, emerging upwardly from the annealing chamber of the drawing apparatus, is scored both longitudinally and transversely and, in order to prevent premature division along the longitudinal lines when the ribbon is snapped along the transverse lines, the former are interrupted adjacent the points at which they would otherwise intersect the latter. The transverse scorer is operated when the leading edge of the rising ribbon engages a switch, not shown. The longitudinal scorers 17 normally engage the ribbon but when the leading edge engages a switch 42, earlier than it engages the switch controlling the transverse scorer, it closes a circuit to open a valve 56 to admit fluid pressure to a cylinder 60, thereby causing a rod 63 to rise and swing a bail 30 to move the scorers 17 out of contact with the glass. The scorers return to contact after an adjustable time by means of a trip member 70, operated by the rising rod 63, freeing the notched arm 51 from the lever 53 controlling the valve 56 thereby permitting the latter to close and the rod 63 to descend and rock the bail 30 in the reverse direction. Specifications 456,822 and 634,553 are referred to.

626,584. Fertilizer distributers. MARKHAM TRACTION, Ltd., and DENLOW, P. M. July 15, 1947, No. 18866. [Class 6(i)] In a fertilizer distributer of the type comprising a transverse trough - shaped hopper 4 having spaced delivery orifices and a continuously rotating agitator 10 in the hopper above the delivery orifices and wherein the orifices are formed by an opening in a slidable cut-off plate 7 which co-operates with an opening in the hopper bottom, a plate 1 having an opening 2 is inserted in each of the openings in the hopper bottom, the plate being flush with the inner surface of the hopper bottom and, at least at the edge of the opening 2, sufficiently thin to give a knife-edge effect to avoid clogging when spreading fertilizers such as super-phosphates. The rotary agitator may be of the type shown in Specification 626,583.

626,583. Fertilizer distributers. MARKHAM TRACTION, Ltd., and DENLOW, P. M. July 15, 1947, No. 18865. [Class 6(i)] In a fertilizer distributer of the type having a transverse hopper having a series of delivery orifices 4, 5 and a continuously rotated member consisting of a hub having its axis parallel and horizontal to the length of the hopper, said hub having above each delivery orifice a sheet metal element A, B having a series of sector shaped blades, each bent out of the medial plane of the element, the direction of bending being reversed in alternate blades, the blades are bent to simulate a helix, the trailing end of the peripheral portion of each blade being positioned near the medial plane of the element. Adjacent elements are oppositely bent. Rotary radial arms may be fitted on the hub between the elements. A cut-off plate 6 is fitted having orifices 7, 8 to vary the effective area of the hopper orifice. The delivery orifices may be arranged as described in Specification 626,584
Abstract:
A control method for a fuel injection valve for an internal combustion engine is disclosed, wherein at least one control signal for actuating a drive of the injection valve is generated in recurring injection cycles and as a function of a target stroke height of a closing element of the injection valve, wherein the drive is actuated by the control signal to lift the closing element to the target stroke height and the closing element is lifted to an actual stroke height by means of the drive, wherein at least one measured parameter correlated with the actual stroke height is captured and the actual stroke height is determined as a function of said at least one measured parameter, wherein the control signal is generated in at least one of the subsequent injection cycles as a function of a deviation of the actual stroke height from the target stroke height.
Abstract:
A method for determining a position of a lock element of an injection valve for an internal combustion engine includes moving the lock element in the direction of a locked position in a closing movement in order to lock the injection valve, subsequently measuring a closure time at which the lock element arrives in the locked position, determining a time difference between the closure time and a preceding starting time of the closing movement, and determining, based on the time difference, a position which the lock element has assumed at the starting time of the closing movement.

Abstract:
An injection nozzle has a nozzle needle that suppresses metering of fluid in a closed position and otherwise allows the metering of fluid. Furthermore, the injection valve has a solid-state actuator that acts on the nozzle needle. A first operating phase is performed for a closing operation in a first operating mode, during which first operating phase the solid-state actuator is discharged to a predefined part charge. Furthermore, a second operating phase is performed, during which the solid-state actuator is operated as a sensor. An operating duration of the second operating phase is predefined such that the closed position of the nozzle needle is reached during the operating duration. A third operating phase is performed, during which the solid-state actuator is discharged further to a predefined reference state. In a second operating mode, the first and second operating phases are carried out and the third operating phase is omitted.
