Title: Improvements in or relating to methods of making substantially non-scalloping bimetallic sheet metal
IPC: B21B1/00
Filed: 1943-03-11
Abstract: 562,723. Making cased forms. SUPERIOR STEEL CORPORATION. March 11, 1943, Nos. 3977 and 3978. Convention dates, March 12, 1942, and Oct. 3, 1942. Drawings to Specification. [Classes 83 (ii) and 83 (iv)] In the production of bimetallic sheet metal having a ferrous metal component and one or more other components having a relatively low melting point, a method of rolling is adopted that results in a product that will cold draw uniformly in a cupping die in spite of it being necessary to terminate the hot rolling stage at a temperature below the upper critical temperature, and without normalizing which tends to grain growth in the low melting point components. After hot rolling, cold rolling follows to reduce the gauge by a percentage depending on the final hot rolling temperature. A curve is given showing the minimum cold reductions for a range of final hot rolling temperatures from 1200 to 1500‹ F. The process is particularly applicable to rolling steel clad with brass of 90 per cent copper and 10 per cent zinc for use in the production of bullet jackets. Steel coated with alloy containing 85 per cent copper and 15 per cent nickel or with silver is also referred to.-

Title: Numerically controlled machine tool
IPC: B24B49/00
Filed: 1964-02-03
Abstract: 1,005,519. Gear-cutting. BENDIX CORPORATION. Feb. 3, 1964 [Feb. 4, 1963], No. 4517/64. Heading B3K. A hobbing cutter 10 is driven by a motor 12, the speed of which is sensed by a quantizer 14 providing an output pulse for a small increment of rotation. The motor 12 is supported on ways 22 and is driven transversely by a motor 20. A workpiece spindle 16 is driven by a motor 18. The output signal of the quantizer 14 and a limit switch 26 are fed to a start control 28 which on the actuation of a start switch, not shown, transmits a signal to a buffer register 38 upon the simultaneous occurrence of the output signals. The quantizer pulses are fed to a synchronizer and direction detector 30 which ensures through inputs 32, 34 to the buffer register that the quantizer pulses fed to a pulse divider 40 represent the net motion of the spindle in a desired direction. The pulse divider 40 comprises (1) a unit 42 provided with three decades of binary coded switches on which is set up the number of teeth to be formed for each rotation of the work spindle, (2) a tooth counter 44 having three decades of binary coded stages, (3) an identity gate 46 wherein their counts are compared and an output pulse developed when the counts are equal. The output pulse resets the tooth counter 44 and through a hob-multiplier 50, which divides the pulse train by two for a double-start hob, is fed to a work-spindle command counter 52 and a feed multiplier 60. The counter 52 provides in conjunction with a reference counter 53 command and reference sinewave signals to a phase analog servo 56 controlling the movement of the motor 18. Commands indicative of the form of the hob are set up through lines 54, 57 on switches, not shown. A helical gear is produced by supplying a differential pulse signal, dependent on transverse feed, through a line 58 from a lead multiplier 74. A feed multiplier 60 modifies the hob multiplier pulse train in dependence on the desired transverse feed in terms of inches per revolution of the work spindle and is set up on binarycoded decade switches 62. The output pulses from the feed multiplier are fed to the lead multiplier 74 and to a feed command counter 64, having an input 66 controlling direction of feed, which through a phase analog servo controls the motor 20. The lead multiplier 74 comprises a five decade binary coded decimal counter controlled by a five decade switch 70 to provide the differential pulses to input 58 of the counter 52. On completion of a work-piece, limit switches, not shown, through line 76 initiate a quick return control 78 operating through the multiplier 60. Correlating the hobbed gear teeth to a reference point on the work-piece is effected, via the lead multiplier 74, by an information set up on five decade binary-coded switches 80.
