Bearing retaining and positioning means

Abstract: An arrangement for retaining and positioning a tapered journal sleeve or bearing on the tapered journal of a rolling mill roll utilizes a circumferential groove in the cylindrical end of the roll, in which groove a number of cylindrical rollers are placed. The rollers have a diameter which is greater than the depth of the groove. Thus the rollers project outwardly from the groove and act as a stop for an extractor sleeve. Hydraulic fluid is used to force the tapered journal sleeve onto or off of the tapered journal of the rolling mill roll.

Dual head measuring techniques for radiation gaging of reinforcing bar

Abstract: A continuously measuring on-line production gage calibrated to indicate bar weight per foot and unaffected by typical reinforcing bar shape variability utilizes two radiation gages with their measuring axes separated by 90 degrees and offset by 45 degrees from the rib plane of the reinforcing bar. Each gage is equipped with a shutter which may be adjusted electrically to simulate any required weight per foot standard and with the gage zeroing on a predetermined shutter setting, the shutter automatically opens and radiation detector signal variations from the zero point are amplified, linearized, averaged, and scaled electronically to produce a percent weight per foot output signal. Summation of detected radiation is also performed through use of optical fibers.

Ultrasonic transducer suspension system for on-line high speed ultrasonic inspection of flat rolled products

Abstract: Apparatus and method for acoustically inspecting hot flat plates while on-line by utilizing an array or arrays of transducers continually spaced a set distance from the bottom of the plates by serrated rollers spring mounted with the array of transducers in a container with overflowing liquid wetting the passing plate to acoustically couple the transducers to the plate and a spray of sufficient force to temporarily cool the hot plate and dispel steam and vapor formed, the spray being in a direction opposite the direction of travel of the hot plate; and support of the unit on a track mounted carriage, with the liquid reused through a reservoir connected system. It is critical that the spray be at an angle of 27° or less to the horizontal and that the spray have sufficient force to have an apparent liquid velocity of at least 44 feet per second, adding the speed of the water and the hot plate together. Also includes associated electronic instrumentation and a rotary pulser with spring biased hinged mounted serrated roller having a cam activated limit switch for enabling the electronic instrumentation and a sprocket and chain connection from the serrated roller to a rotary pulse generator for detecting the position of the plates.
