Title: Method and apparatus to control a blending installation for textile fibres
Inventor: WILDBOLZ RUDOLF
IPC: D01G13/00
Filed: 1981-06-15
Abstract: A method of, and apparatus for, checking a plant for blending textile staple fibres of different types, which are supplied by fibre metering units. The supply of fibres to the storage device is interrupted during repeated time intervals. According to the invention the fibres supplied by an individually operated fibre metering unit, supplying a constant quantity, during part time intervals within the time intervals are transported to a quantity measuring device and are measured. The present invention permits very reliable and precise checking of the fibre quantities supplied by the fibre metering units in such a manner that a desired blending proportion can be maintained precisely. The machines fed from the storage device can be maintained operating during the checking periods, i.e. at all times. The checking operations thus can be effected within relatively short time intervals in such manner that deviations from a pre-set desired value are detected early and that also relatively short-term deviations can be detected.

Abstract: Bei herkömmlichen Stapelfaserschneidmaschinen und auch bei der Maschine gemäß der Hauptanmeldung ergeben sich vor allem bei hohen Schnittgeschwindigkeiten uneinheitliche Stapellängen. Nach den Überlegungen des Erfinders ist eine Ursache dieses unerwünschten Effektes darin zu sehen, daß das freie Kabelende durch Zentrifugalkraft gedehnt wird. Um dies zu vermeiden, ist erfindungsgemäß ausfallseitig hinter dem Messerkranz eine Trommel (20) angeordnet, deren Länge mindestens etwa der Stapellänge entspricht. Die Trommel (20) stützt das heraushängende freie Kabelende ab und kompensiert so die Zentrifugalkraft.

Im Rauchgaszug ist vor jede Wand (6) eine Überhitzerrohrwand (18) gehängt, deren Rohre (32) senkrecht verlaufen und am unteren Ende die Verdampferrohrwand im Bereich der Stege zwischen den Rohren (10) durchdringen. Auf der Höhe dieser Durchdringungsstellen sind die Verdamperrohre paarweise zusammengegabelt und die Überhitzerrohre auf der Innenseite des Rauchgaszuges auseinandergegabelt. Über die Höhe der Überhitzerrohrwand (18) sind Rückhalteelemente vorgesehen, über die die Überhitzerrohre verschiebbar mit der Verdamperrohrwand verbunden sind. Am oberen Ende der Überhitzerrohre sind Mittel zum Ausgleichen der unterschiedlichen Dehnung zwischen Überhitzer- und Verdampferrohren vorgesehen. Durch diese Anordnung werden die Rohre der Überhitzerwand auch beim Anfahren vom Arbeitsmittel gut gekühlt, und es sind unzulässige Wäremspannungen an den Durchdringungsstellen vermieden.

Abstract: A self-tensioning printing cylinder lock for fitting longitudinally in grooves (121) formed between printing saddles (123) on diametrically opposite sides of a printing press cylinder (25). Such lock includes a longitudinally extending base plate (21) having a longitudinally elongated tensioning bar (23) disposed in overlying relationship with respect thereto. The opposite extremities of such bar are urged toward an extended position away from the saddle edge by a pair of identical springs (31) to thus maintain such bar to a position aligned longitudinally with the printing cylinder as a result of such biased spring tension. Consequently, as the length of such printing plate mounted on the saddle varies during operation, the tensioning bar will draw the transversely opposite sides of such printing plate toward such extended position with uniform force to maintain the plate tensioned irrespective of variation in plate length.

Title: Mechanism with contiuous adjustment for the transmission of a rotary motion between two coaxial shafts.
Inventor: FALKNER RAIMUND
IPC: F16H3/00
Filed: 1981-05-21
Abstract: A hub (2) is rigidly torsionwise attached to a leading shaft (1) but free to move axially and radially. A rotary plate (3) is arranged on said hub (2) through a ball bearing (21) and carries a ring (4) provided with four conical transmission surfaces (30, 31). The transmission surfaces (30) of the ring (4) run on surfaces (33) of two rims (7, 8) of a wheel (6) integral with the casing, and the transmission surfaces (31) ran on surfaces (34) of two rims (10, 11) of a second wheel (9) attached to the driven shaft (12) and coaxial with the wheel (6). The distance between the rims (7, 8 and 10, 11) is adjustable. When the driving shaft (1) rotates, the ring (4) effects a slow oscillation motion about the leading shaft (1) and transmits such motion to the wheel (9). The two transmission ranges are offset by 180`. The excentricity is adjustable between a maximum and zero, which allows the obtention of a reduction up to the infinite. A toothing may be provided in the transmission areas. As toothing elements, the ring (4) may be provided with sets of axially free disks and arranged on two rims, which mesh with grooves (71) provided in the surfaces (33, 34). Adjustement devices, preferably in the form of a unit assembly, are used for adjusting the rims (8, 11) and the hub (2).
