IPC: B02C15/02
Filed: 1983-09-05
Abstract: An improved milling process, wherein the material to be crushed is processed within a circular milling path under the action of at least one roller rolling along said path. The material is fed evenly distributed around the circumference of the milling path and enters it with a predetermined initial speed transversely to the extension of the path such that each piece to be crushed is subjected at least once to the action of one of the rollers. Under the action of an air current which is guided across the milling path pulverized material below a given grain size is immediately removed from the milling path, thereby avoiding the build-up of a thick and energy consuming layer on the milling path such that the milling forces are limited to the breaking forces for crushing the pieces fed into the milling path.

Title: Method and arrangement for regulating the path of a positional drive
IPC: B66B1/24
Filed: 1988-04-15
Abstract: A first desired acceleration value (A1) is continuously determined by a non-linear course regulator, and, parallel thereto, a second acceleration value (A2) is continuously determined by a non-linear speed regulator. By means of a simple selection criterion comprising only these two alternative acceleration values, the second alternative desired acceleration value is brought into action by a selection circuit (18) for the running-up, the first alternative desired acceleration value is brought into action for initiating the target braking, and the second alternative desired acceleration value is again brought into action for running into the target position. Changes in the travel target and the speed of the position drive (PA), in particular the realization of creep speeds, are possible to virtually any extent during travel.

Abstract: PCT No. PCT/EP89/00460 Sec. 371 Date Feb. 28, 1990 Sec. 102(e) Date Feb. 28, 1990 PCT Filed Apr. 26, 1989 PCT Pub. No. WO89/10219 PCT Pub. Date Nov. 2, 1989.A device is disclosed for producing expanded material using cutting rollers of special design, in which the individual annular cutting rings on the cutting rollers are provided with notches in their lateral surfaces, and when the cutting roller is viewed from above, these notches are seen to be trapezoidal in shape. The invention relates furthermore to the special configuration of the stretching system, wherein the strip-shaped non-stretched material passing through is gripped laterally by two toothed belts while at the same time the material to be stretched runs up, in its center section, on a recirculating element, such as a rounde-section belt running at an appropriate speed. This belt rises far enough out of the plane of the toothed belts that the desired transverse stretching of the material is achieved. By "expanded material" is meant a foil-like material, usually metal, in which a large number of parallel-oriented incisions are made, so that this material can then be pulled apart transversely to the direction of the incisions; as a result, the material is shortened in the longitudinal direction and the webs of material left between the incisions create a more or less three-dimensional lattice.

Abstract: An operable syringe assembly (20) includes a barrel (21) having an inside surface (22) describing a chamber (23) for retaining fluid, an open barrel end (25), and a distal barrel end (27) having a passageway (28) therethrough in fluid communication with the chamber (23). A plunger rod (33) includes an elongate body portion (34), a proximal end (37) and a distal end (38) with a stopper (39) positioned at the distal end (38). The stopper (39) slidably positioned in fluid-tight engagement in the barrel (21). A locking element (42) is positioned in the barrel (21) between the plunger rod (33) and the inside surface (22) of the barrel (21). Locking element (42) includes a proximally and outwardly facing locking barb (46), a distally and inwardly facing resisting edge (50) and an inwardly facing driving edge (52). Driving edge (52) interacts with the plunger rod (33) to move the locking element (42) along the barrel (21) as the stopper (39) is advanced distally along the barrel (21). The resisting edge (50) and the barb (46) prevent proximal motion of the plunger rod (33) with respect to the barrel (21) after the initial motion of the stopper (39) to expel fluid through the passageway (28) wherein proximal motion of the plunger rod (33) with respect to the barrel (21) causes the resisting edge (50) to engage the plunger rod (33) causing the locking element (42) to move in a proximal direction wherein the locking barb (46) engages the inside surface (22) of the barrel (21) to prevent further proximal movement of the plunger rod (33) with respect to the barrel (21). A barrier element (65) is provided on the plunger rod (33) for limiting the delivery volume of the syringe assembly (20) by establishing the maximum proximal position of the locking element (42) with respect to the plunger rod (33).
