Filed: 1944-09-01
Abstract: 582,293. Rolling. ALLOTT, N. E. Sept. 1, 1944, No. 16669. [Class 83 (iv)] In the production of rods, wire, tubes, rails, sheets, &c. from steel or other metals and alloys, the pause between successive passes is regulated in accordance with the pressure developed in a pass preceding the pause. If the pressure be abnormally high the pause is increased in length and conversely. One indicated pressure may control the pause between several subsequent passes. During the pause radiant heat may be applied. The pressure indicator for rolls may be calibrated in time units and may control the speed of the means for conveying the work to the next pass or the operation of an interposed gate or barrier. In applying the process to work partly rolled not according to the process, the metal should be reheated to a temperature at least as high as that employed during the preliminary rolling.

Clinometers; magnetic compasses.-A clinometer comprises a dip magnet free to swing in all directions but prevented from rotating about its axis; the instrument may be used also as a compass. As shown in Fig. 1, the magnet 1 passes through a spherical float 2 and has attached to it three rings 5, 6, 7 which indicate respectively the horizontal plane, and the N-S, E-W vertical planes. A small weight 8 or the equivalent is provided to cause the centre of gravity of the system to fall below the centre of the float, the whole system floating in liquid in a chamber and having the same specific gravity as the liquid. The chamber comprises a glass container 9 having a brass cover 10 and enclosing an air chamber 12 having a corrugated bottom 14 which permits expansion of the liquid. The container 9 is marked with a lubber line 17, against which orientation marks on the ring 5 are read, and circles 19 providing a scale of inclinations around a zenith point 18. The magnet 1 may be adjustable according to the angle of dip in the locality in which the apparatus is used, being carried by slides 3, 4 on the ring 6, and the ring being graduated. In a modification, Fig. 3, the magnet 1 may be mounted on gimbals, being carried by pivots 3 in a horizontal ring 4 pivoted at 5 in an equatorial ring 7 which is secured to a vertical ring 8 pivoted on a vertical axis in a support 11. The magnet is adjustably secured to a graduated vertical ring 14 having a zenith-indicating disk 15 and a weight 16.
