Title: Electric arc welding
IPC: B23K9/067
Filed: 1955-09-26
Abstract: 801,956. Welding by fusion. UNION CARBIDE CORPORATION. Sept. 26, 1955 [Oct. 29, 1954], No. 27399/55. Class 83 (4). [Also in Group XXXVII] In a method of arc welding using a welding source having a flat or rising volt-ampere characteristic, a consumable metal electrode having a pointed or rounded end is fed at a slow initial rate until the end contacts the workpiece and the arc is started and subsequently the electrode feeding rate is changed to the normal welding feeding rate. Flux submerged or gasshielded arc welding may be employed. For seam welding operation of a starting switch 32 actuates a relay 30 to connect the welding source 24 across the electrode 10 and the workpiece 20 and at the same time to start the feed motor 16. When the arc is struck a detector 40, such as a current relay, actuates a control circuit 38 to increase the speed of the motor 16. When the weld is completed, operation of a switch 44 stops the feed motor 16 and the electrode burns back to extinguish the arc so forming a balled end on the electrode. After a delay determined by a circuit 46 the supply 24 is disconnected. This apparatus was used to weld carbon steel or stainless steel plates with electrodes of carbon steel having less than 0.06 per cent C and 12 per cent Cr steel respectively with gas shield of argon containing 5 per cent oxygen. In a modification for automatically controlled gas-shielded spotwelding, depression of the trigger on a welding gun starts the electrode feed motor at its slow rate and switches on the shielding gas and cooling water. A switch responsive to the flow of water then switches on the welding current. When the electrode contacts the work, the arc is struck and the feed rate is increased to normal. After an automatically determined delay the feed motor is stopped. After a further delay the welding supply is disconnected and later the shielding gas and water flow is stopped. This apparatus was used to spotweld stainless steel using an electrode of 19 per cent Cr-8 per cent Ni steel and a shield of 95 per cent argon, 5 per cent oxygen, galvanized steel sheet using an electrode of copper containing 3.5 per cent Si and 0.75 per cent Mn and an argon shield and carbon steel using an electrode of 0.3 per cent Cr-1 per cent Mn steel with a shield of 95 per cent argon and 5 per cent oxygen.

Title: Improvements in acceleration responsive devices
IPC: G01P15/13
Filed: 1955-09-29
Abstract: 816,779. Measuring acceleration electrically. GENERAL ELECTRIC CO. Sept. 29, 1955 [Oct. 4, 1954], No. 27752/55. Class 40 (1). [Also in Group XIX] In an acceleration responsive device comprising a container rotatably supported about an axis other than one passing through its centre of mass so that linear accelerations transverse to the plane containing the axis and centre of mass apply a torque to the container, and means for applying a counter torque in response thereto, the container is suspended in a liquid, the density of which is such that the upthrust thereof is equal to the weight of the container and its contents. In the embodiment the casing 10 incorporating an unbalance mass 15 is pivoted in bearing means 11 in a housing 12 fixed to the vehicle, the acceleration of which is to be measured. Angular displacement of the casing in response to accelerations normal to the plane of the drawing results in displacement of coil 21 in the air gap of the magnetic circuit 22, 23. The signal thus generated in the coil after amplification at 27 (Fig. 2) is applied to the control winding 16 of a two-phase motor, the rotor 17 of which together with flywheel 18 is freely pivoted in bearings 20. The motor energization is such that the reaction torque on the casing balances the accelerating torque to restore it to a null position. The torque on the rotor, which is therefore proportional to vehicle acceleration accelerates it proportionally so that at any instant rotor speed is proportional to vehicle speed, and, integrated angular displacement to distance travelled. The motor drives rotor 41 of a selsyn transmitter 42, the output of which, operates indicating or control mechanism. The wiring shown in Fig. 2 is omitted from Fig. 1 for clarity. Housing, 12 is filled with a low viscosity liquid, e.g.. heptacosafluorotributylamine of such density relative to the mass of casing 10 and its contents, and the distribution of mass in the casing is such that bearings 11 are unloaded except for acceleration along the rotation axis, when they provide a balancing torque.

Abstract: 715,137. Photo-electric generation of synchronous voltages in quadrature. ROLLSROYCE, Ltd. Nov. 27, 1952 [Nov. 27, 1951], No. 27848/51. Class 40 (3). [Also in Groups XXXVI and XXXVIII] In a balancing machine wherein a pair of A.C. generators each produce a variable voltage determined by the oscillations of an associated bearing support for a rotary body to be tested about an axis normal to the plane of oscillation and passing through the centre of gravity of the body, and the phase angles of such voltages relative to a datum represent the angular position of the unbalance in the plane of each bearing and thus the position at which weight must be added or subtracted to balance the rotor, the angular location is determined by applying the appropriate variable voltage to a phase difference indicator also energized by a reference voltage derived from a phase adjuster energized by two sinusoidal voltages in quadrature having a frequency synchronous with the rotor speed and known phase relationships referred to a datum position of the rotor and derived from photo-electric scanning of a rotating element driven thereby, and by altering the phase adjuster setting until the phase difference indicator shows a predetermined phase relationship (e.g. 180 degrees or 0 degrees). The unbalanced rotor is mounted in a balancing machine of the kind described in Specification 714,351, [Group XXXVIII], for rotation by a balanced belt driven split pulley which carries a coaxial illuminated disc 1 whose circular face is of a light colour superimposed with an eccentric circle 2 of dark colour, the surface being viewed by two photocells 3 positioned on radii of the disc at right angles to each other. The cells produce alternating voltages in quadrature at a frequency synchronous with the speed of rotation of the body and known phase relationship to a datum rotor position, which pass through amplifiers 4 to energize the fixed 90 degrees spaced coils 5, 6 of a goniometer whose rotating coil 7 is adjustable to vary the phase of the output energizing one coil 8 of a wattmeter whose other coil 9 is energized by the vibrational alternating voltage representative of the unbalance of the rotor in a selected plane. The coil 7 is adjustable until the wattmeter indicates that its energizing voltages are in phase or antiphase, and its position then determines the angular disposition of the unbalance in the selected plane.

Abstract: 828,424. Speech transmission. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 4, 1958 [Sept. 4, 1957], No. 28430/58. Class 40 (4). For the transmission of speech over a channel limited to the range 0-4 kc. the band 4-8 kc. which contains important tonal components of most consonants is shifted to that range and transmitted with the normal 0-4 kc. speech band to a receiver where no further conversion takes place. In Fig. 4, the whole band 0-8 kc. is fed over parallel paths A, B, one containing a modulator 14 supplied with a carrier frequency of 8 kc. and the other an attenuator 13 giving the same attenuation as the modulator. The combined output passes through a lowpass filter 34 cutting off at 4 kc. The 4-8 kc. band is thus folded over the 0-4 kc. band. In Fig. 5 (not shown), the path B is restricted to the range 4-8 kc. and a carrier of 4 kc. is used, so that the 4-8 kc. band is shifted without inversion. In Fig. 6, the speech band passes through a gating circuit 37 and low-pass filter 38, the former being controlled by 8 kc. pulses so that the 4-8 kc. band is in effect modulated to produce a 0-4 kc. lower side-band. This arrangement is described more precisely with reference to Fig. 7 (not shown). Specification 142,115 is referred to.
