Abstract: A tire-chain assembly for a vehicle-mounted wheel basically comprises annular inner and outer holders respectively engaging the inner and outer faces of the wheel. At least one traction chain crisscrosses over the road-engaging surface of the wheel between the two holders. The inner holder is of variable diameter, so that it can be fitted over the tire and then have its diameter decreased to allow the traction chain to be tightened on the wheel. Mechanism on this inner holder is connected via a flexible element that passes over the road-engaging surface of the wheel to the outer face of the wheel so that a pull on this mechanism will reduce the diameter of the inner holder and tighten the chain assembly on the wheel. The outer end of this flexible element, which may be a chain, is then secured to the holder on the outer surface of the wheel. A chain comprising a plurality of locking dogs or hooks may be constituted as the tightening mechanism so as to ensure self-locking of the tire-chain assembly on the wheel.

Abstract: In an application to welding generally cylindrical members along a designated circumferential weld seam, the method and apparatus of this invention simultaneously produce substantially identical welds at a plurality of spaced weld zones along the weld seam symmetrically situated about an axis bisecting the axis of revolution of the member by automatically controlling and establishing a substantially identical ratio of heat input to volume of deposited metal along the weld seam at each of the weld zones at any given point in time.  Identical welds are achieved by automatically, programmably, controlling the power employed to preheat the filler material at each welding location as a function of the corresponding filler material feed speed and the respective feed speed and power imparted to each weld zone as a programmed function of the speed of the weld zone along the seam and the respective feed speed and welding power corresponding to each of the other weld zones along the seam.

Abstract: A specific binding assay method and test kit for determining a ligand, such as an antigen or antibody, in, or the ligand binding capacity of, a liquid medium, particularly a body fluid such as serum, wherein the unknown ligand competes with a labeled component, such as a radio labeled form of the ligand or of a binding analog of the ligand, for binding with a binding partner, with the improvement that separation of the resulting bound-species and free-species of the labeled component is accomplished by drawing the liquid reaction mixture into a column of an adsorbent material selective for one of the two species. Separation results by immobilization of the selected species at the beginning portion of the adsorbent column while the other species is transported farther along the column by advance of the reaction mixture. The present method is manipulatively simple and advantageous over the many known techniques; finds special application to radioimmunoassay, particularly for detecting low molecular weight ligands; and is readily adaptable to automation.

Abstract: A method of cleaning a drying wire of a paper making machine using at least one pressurized water jet directed against the surface of the wire by a nozzle. The nozzle is supplied with water under a pressure higher than normal water pipe pressure, preferably a pressure of 430-1300 psi. The increased pressure of the water jet reduces the amount of water remaining in the wire due to increased water flow passing through the wire. Consequently the increased pressure of the water jet makes it possible to clean the drying wire during production and web formation.

Abstract: Sensing arrangements on material rolls are used to give advance warning when the material web forming the roll approaches its end. Usually this involves the sensing of the reduction of the roll diameter with the help of a sensing device resting against the roll periphery. In the case of roll suspensions where the centre of the roll is not fixed, these sensing arrangements cannot be used. Here it is possible instead to use a sensing arrangement which comprises a field-generating element (11), e.g. a permanent magnet, present in the centre of the roll (3), together with a movable sensing device (8) resting against the periphery of the roll, e.g. a heavy current switch which is acted upon at a certain predetermined field strength, and in a suitable manner indicates that a roll replacement is imminent.

Abstract: The invention concerns a method and a device for joining profile pieces, in particular profile pieces which form part of an electrical cable conduit system. The profile pieces 2, 14, 15 are provided with at least one T-track in which a joining device 1 is intended to be arranged so that the device forms a bridge over the site of the joint when the joining has taken place. The joining device 1 according to the invention comprises a rail or rod with a slightly V-shaped cross section. The device has a flexible area where it can be bent or a bend indication 10 which runs along the point of the V, and the side edges 6, 7 of the device are designed to engage with the side edges 4, 5 of the T-track and also to form spacing devices 8, 9 which permit the joining device 1 to be flattened out and pass over a dead-point position. As a result of a knee joint effect in connection with this a relatively small pressure on the bend indication will cause the joining device to be stretched or expanded outwards towards the side edges 6, 7 in the T-track with great force to lock the profile pieces 2, 14, 15 to each other effectively. <IMAGE>
