The resultant reversing mill and coiling furnaces are arranged so that a transfer bar is first reduced as it passes through F-1 in a forward direction and coiled in the downstream coiling furnace, then further reduced as it is passed in a reverse direction through F-1 to the upstream coiling furnace, then further reduced as it is passed the third time through F-1, and then further reduced to the final gauge as it passes successively through F-3 and the remainder of the finishing stands in the finishing train.

Abstract: In the rolling of wire or rod in a rolling line having a roughing or intermediate block whose rolling stands have non-adjustable rolls except for those at the exit end of the block, the rolls of the non-adjustable stands can be re-used at least once in the same stand location after being re-conditioned by reconditioning all the rolls defining a first series of sizing passes so as to form a second series of sizing passes whose individual sizes are larger than those of the first series. The change in dimensions of a given sizing pass as a result of reconditioning is less than the difference between the dimensions of that sizing pass after reconditioning (i.e. of the second series ) and the dimensions of the immediately preceding sizing pass before reconditioning (i.e. of the first series). Thus, after a second or subsequent reconditioning the rolls of a given stand are transferred to the immediately preceding stand for re-use to define the first series of sizing passes.

Abstract: Metal billets to be used for extrusion are cast and quickly cooled to their solidifying temperature to minimize grain growth and are delivered to a tempering oven where they cool to the temperature required for extrusion, thus also evening the temperature of the billet. They are kept at that temperature until taken to an extrusion press one at a time where the billet is maintained against cooling from its extrusion temperature throughout the extrusion time. The billet is of such size and shape that the time between the first solidification of the outer surface and the last solidification of the inner liquid metal thereof is not so great as to cause excessive grain structure. In the extruding machine, the tie rods that resist the extruding pressure are prestressed to prevent appreciable dimensional variations in the press due to normal variations in the extruding pressure.

Both the rod side and the piston side of the other slide are connected both to the pressure pipeline main and the return pipeline.

Abstract: A device for measuring in real time sea currents in deep water possibly exceeding 6000 m, as a function of the depth.A spherical shaped plunger having negative floatability is dropped from a boat and descends to the bottom of the sea, releases its ballast and rises again to the surface where it is recovered.Acoustic responding buoys positioned geographically as well as the contrivance receive pulses transmitted by the boat and respond to the boat. Furthermore, the contrivance also sends out a response intended for the buoys which reply to the boat; from the arrival times of these pulses, a computer on board the boat calculates the sequential positions of the contrivance in relation to the buoys as well as the velocities of the currents as a function of the depth.

Abstract: Method and apparatus for determining diameter and wall thickness of hollow microspheres or shells wherein terminal velocities of shells traveling in fluid-filled conduits of differing diameters are measured.

For shells of known outside diameter, wall thickness may then be ascertained as a predetermined empirical function of terminal velocity in either conduit.

Abstract: A method and apparatus for investigating a rod-like body which is anchored in a surrounding material and which has an accessible end, for determining the state of the anchorage of the body and its length. Transient elastic oscillations are excitated in the accessible end of the body. The oscillations comprise a flexural wave causing a deformation of the body varying with respect to amplitude and phase over the cross-section of the body. The flexural wave propagates in the longitudinal direction of the body and is partially reflected at discontinuities of the body and/or the anchorage. Transient elastic ocillations comprising flexural waves reflected at such discontinuities and returning to the accessible end of the body are received and detected. The position and magnitude and/or type of at least some of the discontinuities are estimated with the aid of time-position and amplitude of the reflected flexural waves.

The effective coupling capacity of the electrodes in each assembly is such as to render the signal substantially immune to the influence of non-axisymmetric flow profiles.

Abstract: A liquid volumetric flow measuring apparatus is disclosed wherein a turbine or vane, flow straighteners therefor, and a rotating shaft mounted therewith, and a magnetic sender are all mounted as an integral unit in a U-shaped pipe trap, and a volumetric calculator is mounted in conjunction therewith.

The magnetic sender has a reed switch and a magnet which are specifically mounted so as to provide low angular momentum and reliability, at both high and low flow rates.
