Title: Magnetic oscillation of welding arc
IPC: H05B7/02
Filed: 1958-01-29
Abstract: 822,792. Influencing electric welding arcs by magnetic flelds. AIR REDUCTION CO. Inc. Jan. 29, 1958 [Feb. 12, 1957], No. 2976/58. Class 39(3) [Also in Group XXXV] In arc welding especially for forming a wide flat bead for' a surfacing operation e.g. welding a coat of aluminium bronze over steel by supplying A.C. of predetermined frequency to a workpiece 10 and to a consuming wire electrode fed to the workpiece to maintain the arc between them as the metal of the wire is melted and transferred in drops to the workpiece as it moves relatively to the arc in a predetermined direction, a magnetic field is created extending in said predetermined direction and reacting with the magnetic field of the arc to produce forces tending to move the molten metal in the arc transversely to said predetermined direction; and at least one of the magnetic fields is varied cyclically with respect to the other at a frequency differing from said predetermined frequency by a difference low enough so that the transfer time of the drops of molten metal from the wire to the electrode is less than half a cycle, so that the molten metal drops in the arc move alternately to one side and then to the other of the line of movement of the wire electrode above the workpiece, thereby spreading a welded coating of substantial width along both sides of the line of movement. The magnetic field for oscillating the arc comprises two magnetic poles 18, 19 placed on opposite sides of the arc and displaced from the wire electrode along the direction of movement thereof in opposite senses. The poles carry electrical windings 20, 21 supplied from an A.C. source 22, preferably with a frequency of 1/5 to 20 cycles per second for an arc length of 3/16 inch to 1/2 inch. The electrode wire is fed continuously down through an electrode head 4 with a supply of inert gas to shield the arc. The supply to the electrode is A.C. or D.C. but when it is A.C. the supply to the magnets is D.C. The difference frequency is high as compared with the travel speed of the particles and to the rate of arc current flow. The A.C. supply may be a sine wave or square wave field. The transfer time of metal drops from the electrode to the workpiece is preferably less than the oscillating frequency but may be as high as half this frequency. The drops may be projected with-a force of 50 to 60 G. A variable frequency source for supplying square wave A.C. is described (see Group XXXV). If the speed of the workpiece is too fast, the deposited bead is a zig-zag, but if the speed is slower, the deposited bead is in the form of a wide ribbon.

Title: An improved fuel control system for a gas turbine engine
Inventor: MARSHALL DAVID
IPC: F02C9/32
Filed: 1969-01-20
Abstract: 1,254,612. Gas turbine engine fuel systems. H.M. HOBSON Ltd. April 17, 1970 [Jan.20, 1969], No.3119/69. Heading F1G. A fluidic vortex valve meters the fuel flow to the main burner of a gas turbine engine, a governor controllable by the pilot adjusts the fuel-pressure at the control port of the vortex valve to maintain the required steady-state engine speed, and means for varying the pressure drop across the vortex valve are operable during acceleration and when the main flow through the vortex valve is saturated, so that the fuel flow is limited during acceleration. Fuel is supplied via a centrifugal pump 1, a cooler 2, a positivedisplacement pump 3 and a vortex metering valve 4 to the main burner. The line 31 supplying fuel to the primary burner also supplies fuel to the control port 5 of the vortex valve 4 via a valve 6 actuated by a all-speed governor 7 under the  control of the pilot's throttle lever 9, whereby the main flow through the vortex valve 4 is governed to maintain the required engine speed. During acceleration, the main flow through the vortex valve 4 becomes saturated, i.e., it cannot be further increased by any further reduction of the pressure at the control port 5. The vortex valve 4 then behaves as a fixed orifice, the main flow through it being controlled solely by varying the pressure drop across it. Variation of the pressure drop is effected by by-passing some of the output of the pump 3 to its inlet via a vortex valve 17. The by-pass flow through the vortex valve 17 is controlled by varying the pressure at its control port 25 by means of a by-pass valve 23 located downstream of a fixed orifice 24. The valve 23 is controlled in accordance with engine speed by a governor 22 and in accordance with compressor pressure by a diaphragm 21 subjected to the pressure drop across a valve 16. The valve 16 is controlled by a capsule 18 subjected internally to a compressor pressure P 3  and an evacuated capsule 27, both capsules being subjected externally to a pressure P x  developed by a potentiometer 19, 20 subjected to the pressure P 3  and a higher compressor pressure P 4 . The valve 16 is located in a by-pass line 11, in series with valves 12 and 13, the valve 13 being controlled by a diaphragm 14 subjected on opposite sides to the pressures downstream of the vortex valve 4 and downstream of the valve 12, whereby these pressures are equalized. The pressure drops across the vortex valve 4 and the valve 12 are thereby equalized, whereby the main flow through the vortex valve is proportioned to the flow through the valves 12, 16 and therefore a function of engine speed and compressor pressure. The valve 12 is opened by an electronic unit, thereby reducing the fuel flow through the vortex valve 4, when the safe operating limit of, e.g. the speed of another engine shaft or turbine inlet pressure is approached. In another embodiment, Fig.3 (not shown), the vortex valve 17 is arranged in series with the vortex valve 4 and acts as a throttle valve instead of a by-pass valve.

Abstract: 1,211,692. Making pre-stressed pressure vessels; welding by fusion. STRUTHERS SCIENTIFIC & INTERNATIONAL CORP. 22 Nov., 1967 [24 Nov., 1966; 20 Jan., 1967], Nos. 52653/66 and 3178/67. Headings B3A and B3R.  A method of making a pre-stressed thickwalled pressure vessel, having a wall thickness at least 16% of its inside diameter, the wall being a curved closing wall of an integral layer of material, includes the step of bending the wall to change its curvature and thereby pre-stress it to resist higher pressures. A cylinder 40, prestressed to resist internal pressure is made with a gap 41 which is closed by hydraulic rams 43 while the cylinder rests on supports 42. When the gap is closed a trench 44 remains in which a first welding pass 45 is made. A chill bar 46 is then used to keep the weld cool while the remaining weld passes 48 are made. A cylinder prestressed to resist external pressure is made by forming halves 61 and 62, the angle subtended by the outer wall of each half being 189 degrees. The halves are assembled and external pressure is applied to bring the meeting surfaces into contact, Fig. 17, before welding. The change in curvature necessary to apply the required prestress is 0À5% for steel and the effect is to produce approximately uniform circumferential stress throughout the thickness of the wall. A helically seamed cylinder may be made either by winding a strip of material on to a mandrel or by machining a helical slot along a tube. The edges of the gap are closed by twisting the tube before it is welded.

Abstract: 1353291 Delta modulators INTERNATIONAL BUSINESS MACHINES CORP 24 Jan 1972 [25 Feb 1971] 3219/72 Heading G4H In a delta or sigma-delta modulator an additional feedback loop is included to correct for drift in the system when the input is zero. As described the output of a comparator C (Fig. 1) comparing the unknown input with the feedback signal stored on a capacitor C1 is applied (1) under the control of regular pulses T1 to a trigger TR1 controlling a switch applying a current source S1 of value 2I to a capacitor C1 and (2) under the control of pulses T2, phase displaced from the pulses T1, to a trigger TR2, the output of which is applied to a correction integrator R2, C2 used to vary the amplitude of a current from a source S2 normally of value - I. The time constant of the correction integrator is selected so that in normal operation the apparatus operates as a conventional modulator. With no input and no drift the trigger TR2 provides a sequence of outputs alternately + 1 and - 1 which are integrated to provide a null correction voltage. If drift occurs, successive outputs from the trigger TR2 are consecutive + 1 or - 1 to vary the current to compensate for the drift. The pulses T2 may, for example, occur midway between the pulses T1.

Abstract: 1437685 Synchronization of sound and vision BRAUN AG 24 Jan 1974 [26 Jan 1973] 03311/74 Heading G2E A sinusoidal control signal for synchronizing the sound track of a film with the visual images is obtained from a rotating part of the camera drive mechanism having a magnetically discontinuous region therein, one pole of a permanent magnet being placed over said region and means for sensing the flux changes being located between the said region and the said pole. As shown, a motor 1 is geared to drive a shaft 5 and hence a shutter 6 which rotates in front of a picture window 7. The shaft has a recessed portion which may be formed by milling a pair of flats 16, 17, or by forming the shaft with an oval section, as in Fig.3. A permanent magnet 18 is placed with its north pole adjacent the recessed portion, with a field plate 19 between them whose output is fed into a sine-wave shaping amplifier 15. The alternation of the recessed and non-recessed portions of shaft 5 forms a constant change in the magnetic circuit. The output voltage of amplifier 15 is taken off at terminals 10, and can be recorded on the sound track of a magnetic tape and used as a pilot or clock sound, the sound to be reproduced during the showing of the film being recorded on the first track of the tape. If the shaft recess has the oval section of Fig. 3, the flux change in the magnetic circuit will be approximately sinusoidal, so that a straightforward amplifier may be used. In a further modification, Fig.4 (not shown), a four-lobed cam provides the magnetically discontinuous region, and the field plate is replaced by an induction coil. Fig. 1 also shows another arrangement in which the discontinuous region is formed by an aperture 23 in a rotating disc 4, the magnet 24 having an adjacent Hall generator 25 for developing the control frequency.
