Title: Improvements in and relating to profiling tracers for an electrically operated copying machine
IPC: B23Q35/36
Filed: 1933-03-16
Abstract: 408,794. Milling-machines. PRATT & WHITNEY CO., 436, Capitol Avenue, Hartford, Connecticut, U.S.A. March 16, 1933, No. 8049. Convention date, Jan. 5. [Class 83 (iii).] In a tracer tor an electrically operated copying machine, of the kind described in Specification 233,747, [Class 83 (iii)], the tracer spindle is capable of endwise movement as well as oscillatory movement, the former movement operating contacts for controlling the in and out motions of the tracer and cutter, and the latter movement operating contacts for controlling the lateral motions of the tracer and cutter. The tracer spindle 2 is mounted for universal movement in a spherical bearing 6 in the casing 1, the bearing being in a reversed position from that described in Specification 233,747 to allow axial movement of the spindle. A collar 16 on the spindle supports an annular contact-carrying member 17, similar to that described in Specification 318,587, [Class 83 (iii)], the contacts being spaced 90‹ apart and co-operating with four fixed contacts 19 connected to relays which control the electromagnetic clutches for the lateral motions of the cutter head. A ring 25 carries a spring 22 connected to the spindle 2 and is rotatable by bevel gearing 27, 39 and a flexible shaft 36 from a handle 43, so as to bias the tracer to close the contacts for movement in any two adjacent directions, as described in Specification 318,587. An extension 45 of the spindle engages a hardened steel button 71 on a lever 54, pivoted at 53, and carrying front and rear contacts 56, 57 which co-operate with fixed contacts 58, 62 respectively, to operate relays controlling the electromagnetic clutches for the in and out motions of the cutter head. A tension spring 67 and a compression spring 68 maintain the lever in contact with the spindle and normally press the latter into its forward position and close the contacts 56, 58 to maintain the in motion of the cutter. Axial pressure on the end of the spindle 2 opens the contacts 56, 58 and closes contacts 57, 62 to control the depth of penetration of the cutter, as described in Specification 233,747, and the button 71 is formed flat or slightly spherical so that oscillations of the spindle will not affect the contact lever 54. The oscillations and reciprocations of the tracer spindle cause it to follow a pattern such as a bead A, Fig. 5, on a surface B which is curved in three dimensions, or to follow an outline pattern A, Fig. 7, which is superposed on a depth-governing pattern B, whereby the depth or thickness of an outline pattern may be varied in the work. The device may form an attachment to the tracer described in Specification 318,587. The Specification includes a wiring diagram of the electromagnetic clutches and relay circuits and also refers to Specification 275,479, [Class 83 (iii)].

Filed: 1953-03-25
Abstract: 767,690. Automatic welding control systems. BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION. June 15, 1954 [March 25, 1953], No. 8291/53. Class 38 (4). In a welding system in which the electrode is fed at a nominally constant rate, arc stability being achieved by a supply system with a drooping characteristic, the arc voltage is compared with a reference voltage and deviations are corrected by a slowly acting control to modify the rate of electrode feed. In one embodiment, Fig. 1, the electrode supplied from a compound D.C. generator G is fed forward by a motor DM having a shunt field regulator R adjusted via reduction gearing RG by a motor M having its armature energized by the resultant of the arc voltage and an opposing reference battery P. In a modification, Fig. 2 (not shown), an amplifying exciter supplies the motor M and has its field energized by the arc and reference battery. In a second modification, Fig. 7 (not shown), the electrode drive motor has a centrifugal governor which is adjusted by the motor M. In a third modification, Fig. 8 (not shown), the electrode drive motor has an infinitely variable gear adjusted by the motor M. In a fourth modification, Fig. 9, the electrode drive motor DM drives through a differential gear 7 with a second input from an auxiliary motor AM, the field regulator of which is adjusted by the motor M. In a fifth modification, Fig. 3 (not shown), the motor M is controlled by a polarized relay connected across the arc in series with the opposing reference battery. In a sixth modification, Fig. 4 (not shown), the polarized relay is controlled by a triode controlled by the arc voltage and the reference battery. In a seventh modification, Fig. 5 (not shown), the reference battery of Fig. 4 is replaced by a neon stabilizer. It is stated that the D.C. generator may be replaced by a transformer and rectifier; that an A.C. arc may be similarly controlled by first rectifying the voltage measured across the arc; and that a photo-cell or bolometer responsive to the arc may effect control in an unspecified manner. Specifications 767,688 and 767,689 are referred to.
