Title: Improvements in nut locks
IPC: F16B39/24
Filed: 1929-12-09
Abstract: 335,464. Steinhorst, W. Dec. 7, 1928, [Convention date]. Washers for locking nuts are formed with a number of sector shaped flaps arranged closely side by side and helically bent so as to present tooth-like projections at the upper and lower face of the washer and the flaps are arranged partly to over-lap each other at adjacent edges. In the manufacture of these washers upper and lower dies of identical form and presenting convex shaped projections spaced from each other so as to permit of laterally stretching as well as cutting and bending the sectors are employed. The washers s have sector shaped flaps l, l<1>, l<11> closely arranged side by side by radially cutting into the blank, and are helically bent and finally stretched and lengthened so as to over-lap each other. In producing the washer, compound cutting bending and stretching dies o, u are employed, these dies presenting convex shaped projections p, p', p", t, t', t<11> spaced apart from each other so that with dies positioned as in Fig. 3, the flaps are cut and bent and by turning one or other around its axis through an angle commensurate with the space between cutting and bending elements of the die the lateral stretching of the flaps is effected. Alternatively, a second set of dies o<1>, u' set permanently for stretching may be used. Instead of forming the flaps at the inner periphery of the washer, they may be formed on the outer periphery or on both peripheries.

Abstract: 1,271,412. Measuring fluid-pressure electrically. UMC ELECTRONICS CO. Aug. 1, 1969 [Aug. 2, 1968], No.38744/69. Heading G1N. The pressure of fluid in a line 15, Fig. 3, is determined by expansion of the line due to fluidpressure variations therein, such expansion being detected by a transducer 28 which may be Piezo-electric, a differential transformer, capacitive or magnetostrictive. In an alternative, Figs. 9-11 (not shown), the transducer is a pressure sensitive transistor. As described, the line 15 is a fuel line of an I.C. engine fuel injection system, fuel injection occurring upon a pre-set pressure existing in line 15. Fig. 8 shows circuitry, including the transducer 28<SP>1</SP>, for determining the time between the occurrence of a predetermined position of an engine piston and the occurrence of fuel injection into the cylinder associated with said piston, the timing then being adjusted either manually or automatically if the measured time deviates from a set value. A bi-stable multi-vibrator 53 measures this time between, the piston position being determined by an electromagnetic pulse generator 18, 19, mounted on the flywheel 13, Fig. 1. The output of 53 may be integrated and applied to an operational amplifier 55 to which is also applied a signal representative of the engine speed, the amplifier producing an output representative of the angle between the position of the crank-shaft at the time of fuel injection and at the predetermined piston position. This output is applied either to a meter 56 or a servo 57 connected to the injection advance 58. The fuelpressure dependent signal may be applied to a strobe light 59 to enable manual adjustment, or to an integrator 60 and meter 62 to enable the injection volume to be measured.

A pilger rolling mill, of the kind in which a billet is turned between successive rolling steps, includes a lobed cam which modifies the indexing of the billet so that the billet does not rotate through exactly 60 degrees at each rolling step, thus distributing wear on the rolls by the billet more uniformly. A stand 1, including rolls 7, is reciprocated by cranks 2 from a motordriven crank-shaft 4, an indexing control shaft 12 being driven from a common gear-box 5. Rotation of the rolls is produced by the meshing of pinions 9 with fixed racks 8, while the shaft 12 and a gear-box 11, provide rotation and axial feeding of the billet 30 on a mandrel 29. The shaft 12 rotates a three-lobed cam 22, Fig. 3, at a 3 to 1 reduction ratio, and simultaneously rotates a worm 18 which in turn drives a billet rotating shaft 20 through a worm-wheel 19. The rotation of the wheel 19 is modified by axial movement of the worm 18 superimposed on its rotation, caused by a follower 23 rolling on the cam 22.
