摘要： Wire coming hot from a rolling mill is carried to a coil stacker on an apertured conveyor on which it cools after being deposited thereon in a series of overlapping loops by a dispenser including a continuously rotating tubular arm which is centered on a horizontal axis. A cutter ahead of the dispenser, responsive to a delayed trigger pulse from a photocell which monitors the entry of the leading end of the wire into an observation zone, removes the irregularly formed leading portion of any fresh length of wire but is inhibited from operating at instants when the arm is so oriented that the tip of the trimmed wire would reach its exit end in a position in which the wire tip could become entangled in the mesh with a grid-type conveyor or fall between parallel conveyor bands. This inhibition is brought about by a signal generator, such as an inductance co-operating with a magnet carried by the rotating arm, whose output either enables the cutter drive in a predetermined arm position or blocks it during the passage of the arm over certain parts of its orbit.

摘要： Method of detecting the location and extent of superficial faults, especially cracks, and for measuring the depths of such cracks in bars, billets, blooms, ingots, rods and tubes, especially of noncircular cross section. An electric current is passed axially through the elongated metallic body in one direction, and the magnetic flux of field (crossflux) generated by the passage of the electric current through the body is detected along the surface thereof. To avoid or reduce the effects of the edges of the noncircular body upon the detected magnetic field strength or flux and, therefore, to reduce the possibility that longitudinal cracks in the region of these edges will be undetected or poorly evaluated, the electric current passed axially through the bar is pulsed with the pulse shape being selected such that, in relation to the geometry of the bar, cracks in the surface in the region of the edges are detected. The pulsed current may derive from, say, a 50 or 60 Hz line source subjected to half-wave rectification; preferably pulse frequencies of 20 to 100 Hz are used. Periodically, or prior to each pulse, an erasing pulse is passed through the bar in the opposite direction to eliminate the residual magnetism from the previous scanning pulse or pulses. Hence the magnetization pulse is applied only to a nonmagnetized or previously demagnetized body.

摘要： An apparatus for the charging and sealing of shaft-type furnaces in which a pair of sliding-plate gas locks are provided above and below a roof-shaped distributor in the charging housing. The distributor coacts with a pair of swingable flaps to prevent free flow of the charge, the flaps being simultaneously swung in opposite senses to open chutes for the charge into the furnace when the lower gate is open.

摘要： An apparatus for charging shaft-type furnaces in which a pair of gas-lock gates are provided in vertically spaced relationship at the top of the furnace and above the upper gate a conveyor or the like delivers green pellets of metal or for charging the furnace. Between the two gates, there is provided a clamshell charging arrangement having two halves together forming an upwardly open bucket and adapted to swing apart to release the pellets into the chamber. The device has a funnellike configuration with downwardly convergent walls against which the bottom walls of the bucket lie when the shell halves are swung apart.
