Patent EP-0309635-A1 (EP)
Inventor: BISCHOF STEFAN DIPL-ING FH
IPC: B41J19/00
Filed: 1987-09-28
Abstract: In a device for tensioning a tractor element (1) in a printer, particularly in a matrix printer, the carriage (2) is capable of moving backwards and forwards in a guide (3) and the continuous tractor element (1) is led over a fixed-position, driven, first deflection roller (5) mounted so as to be able to rotate and over a second deflection roller (6) mounted so as to be able to rotate and adjustable in the sense of increasing the tension of the tractor element (1). In order to produce an extremely simple tensioning device from only a few parts which is reliable and, therefore, capable of economical manufacture and assembly, it is proposed that a pair of pedestal bearings (10a, lOb) are provided in at least one side panel (8) of the printer frame parallel to the course of the tractor element (1), which form an opening (9) between them and possess radial cams (14) and longitudinal guides (11) for the roller shafts (5a, 6a), that between the pedestal bearings (10a, lOb) a tensioning body (15) with bearing slits (16) for the roller shafts (5a, 6a) can be introduced, which with the radial cams (14) of the pedestal bearings (10a, lOb) features self-limiting interacting cam followers (17), and that by turning the tensioning body (15) the tractor element (1) may be put under tension. <IMAGE>

Abstract: A blowing device with blowing nozzle for emitting a con­centrated, aimed pressurized air jet and incorporating a feed channel (7) having at least one slot-formed exhaust passage (3), which determines the flow quantity through the blowing device. The purpose of the invention is to create a concentrated air flow, well adapted for cleaning, preferably in the component producing industry, having low noise generation at the object blown upon, within the mixing zone and also at the exhaust opening, at critical as well as particularly at sub-critical flow. This is obtained with the blowing device according to the invention in that the exhaust passage or passages (3) is/are constituted by a number of very thin, relative to their width elongated slots (4) located around a common slot center portion, that the ratio between the smallest slot length (L) and the biggest slot width (B) is bigger than 5, preferably bigger than 12, that the most narrow section of the exhaust passage/passages (3) is situated inside the end plane (2) of the nozzle, thus that the expansion zone for the pressurized gaseous fluid is situated outside the end plane (2) of the nozzle and that the extension of the slots (4) in the direction of flow is such that the dynamic pressure of the jet of air, at escape of pressurized gas at critical flow velocity, e.g. air of a feed pressure of 6 bar and the temperature 293° K, by adiabatic expansion, during its exit to the surroundings, is higher than the atmospheric pressure, preferably considerably higher.

Abstract: A method is provided for recovering particulate crystalline poly(arylene sulfide) from a polymerization reaction resulting in a liquid reaction mixture, comprising a liquid-phase poly(arylene sulfide), a polar organic solvent, and water. The liquid reaction mixture is contacted by an amount of a vaporized phase separation agent at least sufficient to effect a phase separation of the liquid-phase poly(arylene sulfide) component from the polar organic solvent component. The vaporized separation agent comprises a vaporized liquid which, when in its liquid-phase, is characterized as (1) soluble in said polar organic solvent, (2) a nonsolvent for poly(arylene sulfide), and (3) able to effect a phase separation of the liquid-phase polymer from the polar organic solvent. A subsequent reduction in the temperature of the liquid reaction mixture produces a reaction mixture slurry comprising a particulate poly(arylene sulfide). Also provided is a method for recovering particulate crystalline poly(arylene sulfide) from a polymerization reaction resulting in a reaction mixture slurry comprising a particulate poly(arylene sulfide), a polar organic solvent, and water, wherein the particulate poly(arylene sulfide) is liquified resulting in a liquid reaction mixture. The liquid reaction mixture is contacted by the vaporized phase separating agent as described above. A subsequent reduction in temperature of the liquid reaction mixture produces a reaction mixture slurry comprising a particulate poly(arylene sulfide).

Abstract: The invention relates to a safety clutch for intermediate connection between a handling unit (1) and a gripper (3). No use is made of the previously known mechanical solutions with pretensioned springs and guide parts, but rather the safety clutch is locked by means of permanent magnets (8). These permanent magnets (8) are fitted to the safety clutch, which is a three-part design, either on a flange (2; 4) or on an intermediate ring (7). They are expediently arranged in pairs and evenly around the circumference of the flanges (2; 4). Perpendicular prisms are provided as mating pieces corresponding to the angular arrangement of a permanent magnet pair, which prisms in each case engage in a pair of permanent magnets and thus lock the safety clutch. <IMAGE>

Abstract: A method of manufacturing a colour display tube having a magnetic quadrupole post-focusing mask (17) in which magnetic field shaping means (30,31) of soft iron, or the magnetic equivalent, having raised portions, for example strips (32), are placed against opposite sides of a mask sheet (17) and are then subjected to an external strong magnetic field by an electromagnet (34,35) to induce magnetic poles through the thickness of the mask sheet. The geometric arrangement of the raised portions of the field shaping means (30,31) is such that cyclically a north pole, a south pole, a north pole and a south pole are induced into the sheet material surrounding each aperture. Using this technique the entire area of a mask sheet can be magnetised in one operation. Also masks for small tubes and high definition tubes can be made. 
     Quadrupole lens fields which are of variable predetermined strengths can be produced by either varying the applied magnetic field across the mask sheet or selectively partially demagnetising an already magnetised mask sheet.
