Abstract: A driveshaft, which is in driven connection with a motor or a geared motor, has a coupling device for holding rotationally symmetrical tools provided with a shank, for example milling, polishing or grinding tool heads. In order that such a driveshaft permits simple handling of the tool heads, particularly for machining small workpieces and for use in the field of beauty care, and which permits simple connection of the tools to the coupling device and their rapid replacement, the driveshaft (1) consists of a flexible steel wire with a circular cross-section or of a flexible wire with a plurality of layers enclosing it concentrically, which layers consist of wire wound around this wire, which driveshaft is guided in a plastic hose (2) or helically wound steel wire with windings (3) which are located essentially packed closely together. On the side opposite to the motor, a housing (6) in the shape of a tubular piece is connected to the helically wound hose (2), a cylindrical coupling piece (7) being supported rotatably in the housing (6). A permanent magnet (12) is held in the coupling piece (7), whose rear end is centrally connected fixedly to the front end of the driveshaft (1). In its front end face, the coupling piece (7) has a central, axially running hole (17) with a quadrilateral or polygonal cross-section, into which the cylindrical tool shank (24) can be pushed through a front opening of the housing (6), which tool shank (24) has an end part (26) with a cross-section corresponding to the cross-section of the hole (17) and with a flat end face (28), which in the coupled state rests, in the abutting manner on a flat pole face (29) of the magnet (12) which forms the base of the hole (17).

Abstract: A space communicating with the atmosphere via a cavity and a passage is supplied with a fluid or drained by means of a tube (10) made of a flexible elastic material and having a tendency to coil up. Upon insertion into said space, the tube (10) is first held in a straightened-out condition by means of a guide (15) of flexible but unelastic material which is introduced into said tube (10) and then withdrawn therefrom to permit the tube (10) to coil up within the cavity and to be conveyed into the space by a substance supplied to the cavity. The method can be used advantageously for supplying a drug or nutriment directly to the intestine by conducting the tube (10) in its straightened-out condition through the nose, the throat and the gullet down into the stomach where it is allowed to coil up in order to be transported into the intestine by normal ingestion of the food. 
     The tube (10) employed for carrying the method into effect consists of a flexible plastic or rubber material and tends to coil up with a predetermined force, the guide (15) consisting of flexible but un­elastic material and tending to straighten itself out with a force exceeding the coiling-up force of the tube (10).

Each cell is associated with exactly one set of several sequence sets of the auxiliary function used for the band spreading. Sequences from various sets have the characteristic, pair-by-pair, that the absolute values of the normalised periodic cross-correlation functions are much smaller than one and in a case of sequences within a set, the cross-correlation function is optimally small around the zero point pair-by-pair. In the base station (BS) the transmitted signals are data-synchronously processed for all simultaneous connections and the data clock of the received signal is used as data clock of the transmitted signal of the user station (MS).

Abstract: To prevent crack occurence at groove bottoms on both side areas of foam rubber tread of all-season studless tires, a pneumatic tire having a tread surface portion (3) composed of at least two outer and inner rubber layers (3A, 3B) is characterized in that the hardness of the inner rubber layer (3B) is from 54 to 80 degrees in Shore hardness and is higher than that of the outer rubber layer, and further the outer rubber layer (3A) is made of foam rubber with a foam rate from 5 to 50% with at least 10% volume ratio with respect to tread volume. The outer foam rubber layer serves to improve tire performance on icy and snowy roads in winter, and the inner ordinary rubber layer serves to reduce change in groove width after vulcanization, that is reduce dynamic strain concentration at lateral grooves and therefore to reduce crack generation at the lateral groove bottoms.

Abstract: Method using a non-steroidal antiinflammatory compound, such as indomethacin and/or a growth factor that causes a change in cell function when bound to a specific cell surface receptor, such as epidermal growth factor (EGF), to enhance healing and restore function of the corneal endothelium. The compositions can be administered alone, in combination, or in sequence, before or after injury, for example, in an irrigation solution or in combination with a nutritive solution for storage of a cornea prior to transplant. 
     Examples of useful growth factors include, in addition to EGF and EGF-like compounds, fragments of EGF containing the receptor binding region, and EGF modified to improve stability, increase half-life, or enhance permeation into the eye. Examples of other non-steroidal antiinflammatories include aspirin, ibuprofen, and suprofen. The composition can be applied topically to the eye or delivered in a controlled fashion by means of a material such as a polymeric implant, gel, or liposomes. 
     The effective dosage is that amount which promotes closure of corneal endothelial tissue and restores function, i.e., restores permeability, including both barrier function and pumping function.
