Abstract: Discussed are therapeutic approaches to the treatment of thrombolic conditions. The therapies use thrombolytically active proteins which inhibit reocclusion in the subject. The proteins are administered in two or more boli.

Abstract: A centrifugal pot spinning process for spinning yarn of classical character is provided in which either in one stage a fully twisted yarn or in a first stage a partially twisted yarn is spun in a centrifuge (6) and removed from it and, in the case of the partially twisted yarn, the remaining twist is imparted to the yarn in a second stage upon removal while being wound up. A centrifuge (6), a drawing frame (1), a piecing mechanism (2), and a traversing thread guide tube (4) are used. The centrifuge (6) rotates in a space (7) under reduced pressure (pu). Normal air pressure (pn) prevails inside the centrifuge (6) and spinning is carried out under normal air pressure (pn) inside the centrifuge. The reduced pressure (pu) is adjusted in such a way that, during rotation of the centrifuge (6), essentially only the bearing friction of the centrifuge still occurs but the air friction of the outer wall of the centrifuge (6, 35, 45, 53) against the housing (5') is largely suppressed.

Abstract: Discussed are therapeutic approaches to the treatment of thrombolic conditions. The therapies use thrombolytically active proteins which function by, e.g., inhibiting reocclusion in the subject. The proteins are administered in two or more boli.

Abstract: A method of cleaning window furnishings while located in their place of use, in which the furnishings are pushed together to form a vertically hanging block and a wetting medium is circulated from above. A cleaning washing medium is thereafter circulated from above, followed by a rinsing liquid also from above and over the window furnishings. The furnishings are then dried, and surplus fluids are collected at a base of the furnishings. All procedures are carried out while the window furnishings are hanging vertically in their locations of normal use. The wetting medium, washing medium and the rinsing liquid flow downward due to gravity with uniform velocity and cover the furnishings uniformly.

Abstract: In a method of cleaning window furnishing portions such as curtain slats, the window furnishing material to be cleaned is left in the installed condition of hanging on a runner rail or track, pushed together to form a block. Washing-action medium and thereafter rinsing liquid are circulated from above over the window furnishing material which is then dried after the rinsing operation. The apparatus includes a washing device adapted to be hung on the runner rail and has a casing which in use encloses the window furnishing material. A nozzle assembly of the device is thus disposed above the window furnishing material, for washing-action medium and rinsing liquid to be pumped over same, and a receiving trough is arranged below the material to receive the liquid therefrom.

Abstract: A diaphragm regulating valve for the flow regulation of a fluid medium. The valve includes a housing having two halves defining a flow channel. A plurality of diaphragm elements in contact with one another are arranged for insertion into the flow channel to control fluid flow therethrough. An actuating mechanism is provided to move these diaphragm elements as desired. One or both of the housings have radial ribs forming a star in the flow channel and covering the contact edges of the diaphragm elements when the valve is closed.

Abstract: An apparatus for removing impurities from fibrous material such as cotton comprising a first and second clothed driven roller with said second clothed driven roller being in fiber transfer relation with said first clothed roller. A rotating cylindrical cage is provided for receiving said fibrous material from said second clothed roller by means of an air stream flowing through a passage which tapers towards said cylindrical cage. A suction is applied to the interior of the cylindrical cage for drawing air through the periphery of the cage for removing impurities from the fibrous material passing therethrough. Passages are associated with said first and second clothed rollers and have separating edges provided therein for aiding in removing impurities from said fibrous material as it passes over said rollers.

Abstract: A method and apparatus for eliminating an abnormality in a thread being produced by a spinning element of an open-end spinning device and wound on a bobbin. A knotting device is placed in the path of the thread extending between the spinning element and the bobbin. A sensor senses the abnormality in the thread which may be a break or a thin or thick spot therein. If the abnormality is a break the end is placed in the spinning element for being attached to thread being produced therein. This, in turn, causes an abnormality in the thread. A cutter severs the thread at the point of abnormality and the severed portion is carried away. The knotting device is used for tying the ends of the severed thread together during the knotting operation the thread being fed from the spinning element is stored intermediate the knotting device and the spinning element and at the conclusion of the tying operation the length of thread stored intermediately is run down until completely used up.
