Patent number: 4790151Abstract: A front yarn guide element (11) of the yarn stop motion (10) has the shape of a yarn guide eye (12) formed by a wire spiral into which a yarn can be introduced from the side and deflected to all sides without danger of slipping out. The yarn guide eye (12) is provided with a supporting part (17) located so as to be longitudinally movable in the housing (18) of the yarn stop motion (10), so that the spacing of the yarn guide eye (12) from the position (B) at which the yarn stop motion (10) is secured is adjustable.Type: GrantFiled: September 30, 1987Date of Patent: December 13, 1988Assignee: H. Stoll GmbH & Co.Inventors: Ernst Goller, Fritz Walker, Franz Schmid

Patent number: 4790152Abstract: A fabric draw-off arrangement for flat knitting machines has a driven fabric draw-off member consisting of a plurality of roller elements and pressure rollers of a fabric pressure member associated with the roller elements which are mounted on a common rocker shaft and are adjustably and resiliently pressable against the respective roller element. In order during knitting to achieve automatically adjustable reproducibly uniform knitting draw-off, the pressure rollers are together pivotable by motor means into variable end positions and are pivotable from these positions and the pressure force of each pressure roller is individually adjustable by motor means.Type: GrantFiled: November 12, 1987Date of Patent: December 13, 1988Assignee: Universal Masachinenfabrik Dr. Rudolf Schieber Gmbh & Co.Inventor: Otto Geitner

Patent number: 4790153Abstract: In a safety device, in particular for flat-bed knitting machines, with which, by means of a shutoff device, stoppage of the carriages associated with a drive apparatus of the machines in the event of a change in the power of the carriages as compared with applicable normal operation resulting from disruptions in removal of the goods, loop formation and yarn insertion, excessively high loop tightness specification or the like, is effected. A measuring device is provided for detecting a torque-proportional variable of the drive mechanism. Actual values of the torque-proportional variable are deliverable to a central processing unit and an adjustable comparator device, and the comparator device is provided by the central processing unit, with threshold values for this torque-proportional variable, serving as processed actual value for the torque-proportional variable. Finally, by means of the comparator device, the shutoff device is triggerable as soon as the applicable threshold value is exceeded.Type: GrantFiled: November 13, 1987Date of Patent: December 13, 1988Assignee: H. Stoll GmbH & Co.Inventors: Jurgen Ploppa, Gerd Mak

Patent number: 4790154Abstract: The device comprises a plurality of superimposed selection levers, individually pivoted at an intermediate portion thereof to a supporting structure. The selection levers have an end facing the needle-bearing cylinder in the region of the selectors and are oscillable on a plane parallel to the extension of the plurality of selection levers to interfere or not interfere with the heels of the selectors. An actuating lever acts on the other end of each selection lever, is pivoted at an intermediate portion thereof to a frame, and can oscillate on a plane parallel to the plane of oscillation of the selection levers. For the oscillation of the actuating lever, two electromagnets, arranged on opposite sides with respect to the fulcrum of the actuating lever and alternately operable, are employed.Type: GrantFiled: June 15, 1987Date of Patent: December 13, 1988Assignee: Lonati S.p.A.Inventor: Francesco Lonati

Patent number: 4790155Abstract: A fluid nozzle assembly is disclosed for dispensing liquid dye onto an underlying fabric in a substantially closed structure provided with an inert gas atmosphere. The assembly includes an elongated rotatable housing provided along its length with a relatively narrow opening or slot. An elongated manifold, provided with a plurality of laterally spaced dispensing nozzles, is concentrically mounted within the housing so that the nozzles are aligned with the slot. The housing and manifold are rotatable from a first operative position where the nozzles are in communication with the interior of the structure, to a second inoperative position where the nozzles are substantially isolated from the interior of the structure so that the nozzles may be removed for maintenance, cleaning or replacement without significant loss of inert gas from the interior of the structure.Type: GrantFiled: November 18, 1986Date of Patent: December 13, 1988Assignee: Burlington Industries, Inc.Inventors: Vernon T. Daniel, Jessie Gettliffe

Patent number: 4790157Abstract: A locking apparatus for sliding doors which comprises a first leaf and a second leaf slidable in a groove, and including a hooking assembly mounted at the side frame of the first leaf and a hook-retaining block mounted at the corresponding side frame of the second leaf. The hooking assembly comprises a vertically slidable locking block which can be elevated by applying a key into a lock outdoors or by manual lift indoors such that the sliding door will be locked. An overriding safety lock pivotal on the hooking assembly keeps the slidable locking block at its uppermost (locked) position if the overriding safety lock has been pushed.Type: GrantFiled: May 18, 1987Date of Patent: December 13, 1988Inventor: Andrew Lin

Patent number: 4790158Abstract: A pressure-resistent locking mechanism for locking a door of a switch cell accommodating a switching device includes two pivotable locking bars positioned in hollows formed by U-shaped door edges and U-shaped portions of the wall of the switch cell at a hinge side of the door and a closing side of the door. The locking bars are pivoted between a locked position and a released position by pivoting levers against the forces of respective springs. The springs always urge the locking bars to the rest position.Type: GrantFiled: October 14, 1986Date of Patent: December 13, 1988Assignee: Felten & Guilleaume Energietechnik GmbHInventor: Rolf Dirks

Patent number: 4790159Abstract: Apparatus for securing against removal of the hinge pin of a door or other closure. The arrangement comprises an inner sleeve with holes to align with a hole in the hinge pin to accomodate a holding pin. An outer cylinder encloses the inner sleeve to prevent the escape of the holding pin. A wafer lock has a body which extends through the outer cylinder into the inner sleeve which is provided with internal notches or grooves. Removal of the key causes wafers to extend form the key body to grip the notches or grooves thereby preventing removal of the hinge pin from the hinge. Other embodiments of the inner sleeve fascilitate its use.Type: GrantFiled: March 11, 1988Date of Patent: December 13, 1988Inventor: Roy C. Quinn

Patent number: 4790160Abstract: The invention relates to a lock comprising an assembly of identification plates provided with coding notches. A flat key, presenting a coded side, pushes the plates until their notches are brought into alignment, in which a feeler then comes into mesh by a rectilinear edge. The plates, continuing to slide under the thrust of the key, take along, via the feeler, a member for controlling the bolt. An alarm device indicates any introduction of an unsuitable key.Type: GrantFiled: March 2, 1987Date of Patent: December 13, 1988Inventor: Michel M. Chateau
