Title: Torch height control for flame cutting machines
IPC: B23K7/00
Filed: 1973-11-30
Abstract: 1414437 Automatic control of position CATERPILLAR TRACTOR CO 30 Nov 1973 [1 Dec 1972] 55722/73 Heading G3R [Also in Division B3]  The distance from a workpiece of a flame cutting torch is controlled in accordance with sensed variations in the effective resistance of the flame. As described, a series of cutting torches 12A, 12B are moved parallel to respective workpieces 13A, 13B in response to signals from a template scanner (21), Fig. 1 (not shown). The vertical positions of the torches are controlled by servomotors (23A, 23B) connected to respective control circuits (51A, 51B) and a master regulating circuit 53. Each cutting flame 14 is connected in series with a fixed resistor 61 across a regulated D.C. voltage supplied by circuit 53, and the junction point of the resistor 61 and the torch 12A is connected to a summing junction 68 along with a reference voltage from circuit 53 and an individual bias voltage from a potentiometer 73. The junction 68 is connected to one input of an operational amplifier 77 producing an output signal, limited by Zener diode 82, for energizing either one of two relay coils 87, 89 causing the torch to be driven down or up respectively. Any discontinuity in the workpiece causes a high output from amplifier 77 which breaks down Zener diode 91 turning on a warning light-emitting diode 98 and a transistor 94 which earths the amplifier output, thus preventing torch drive. Individual torches can be driven  manually using a switch 103, and all torches can be driven simultaneously be operating a switch 99. In use, an initial high pre-heat stage using propane and low pressure oxygen supplies, Fig. 1 (not shown), is followed by a normal pre-heat stage with reduced propane and oxygen flow. For actual cutting, high pressure oxygen is also supplied to make the flame hotter. Different reference voltages for the pre-heat and cutting stages are provided by the master height regulating circuit 53, the action of turning on the high-pressure oxygen supply also switching contacts 69, 72 so that a potentiometer 67 provides the reference in place of potentiometer 66.

Abstract: 1,143,329. Fuelling reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. 14 Dec., 1967 [5 Jan., 1967], No. 56763/67. Heading G6C. A reactor core 10 situated within shielding 12 constituting the pressure vessel is refuelled by apparatus A situated within the pressure vessel and separated from the core by a partition 20, apertures (not shown) in the partition and closable by plugs permitting the grab (not shown) of a manipulator 44 to react the fuel channels in the core. The apparatus A comprises a main arm 22 rotatable about the vertical axis of the reactor and supported by rollers 24, 26, 28 engaging three circular tracks, the arm being driven by a motor 30 through a pinion 34 engaging an annular toothed wheel 36 connected to the arm. Motor means on the manipulator 44 enable it to be displaced along the arm 22 and also control the grab. The outer end of the arm 22 carries a container 40 having sufficient cells to receive all the fuel elements of one channel, the inner end of the arm carrying a container 38 for receiving the plugs closing an aperture in the partition 20. In use, the manipulator 44 traverses to and fro along the arm to place the plugs from a selected aperture by means of the grab, into the container 38. Further to and fro movement of the manipulator enables the grab to place the fuel elements of the selected channel into the container 40. The spent fuel elements are removed from the container 40 by apparatus B comprising a tunnel 46 carrying a track 52. A duct 64 from the tunnel leads to a vessel 66 in a compartment 76 having a hoist 78. In use, the arm 22 is aligned with the track 52 and the manipulator 44 removes the fuel elements from the container 40 and lowers them into the vessel 66. Subsequently, the hoist 78 removes the fuel elements from the vessel 66 and lowers them through a duct 82 to a spent fuel store. To provide against breakdown there is a duplicate tunnel and manipulator and a shorter rotatable arm 22<SP>1</SP> in the pressure vessel may be aligned with the main arm 22 so that the duplicate manipulator may be transferred on to the arm 22 supporting the failed manipulator, the failed manipulator then being moved on to a track 54 in a lock formed by valves 48, 50.

Abstract: 1,220,528. Telephone answering device. ANSAFONE Ltd. 18 Sept., 1969 [29 Nov., 1968], No. 56823/68. Heading H4K. A telephone answering device has a circuit including a magnetic core arranged so that the direction of magnetic flux through the core is reversed when a brief discontinuity in line current occurs. The change in direction of the flux produces an output pulse which is used to operate a switch to react the device. As shown, two saturable core transformers are used each with its own primary and secondary windings connected in series, in the same sense on one (secondary) side and in series but in opposed sense on the other (primary) side. With currents I 1  and I 2  flowing both cores will be saturated but when I 1  disappears, at the end of a call, the core, where the fluxes due to currents I 1  and I 2  oppose, will change its direction of magnetization and an output voltage pulse will be produced. The direction of currents I 1  and I 2  are irrelevant to the operation of the circuit. The output pulse is used to change the state of the answering device by operating relays through an electronic switch.

Containers are formed from flattened tubular stock by feeding the stock into one end of a heating apparatus to plasticize it, introducing air into the stock to expand it on plasticifiation and vacuum-forming the expanded stock into a container and separating it from the stock while closing the end of the stock. As shown in Fig. 1, flattened tube 11, which may be printed, is passed from reel 12, air being supplied through shaft 13 thereof, and fed by jaws 17-18 and 20-21 joined on frame 19 into heater 22. The tube 11 is plasticized and expanded, the expansion being regulated by mechanical sensing arms 39, acting through arm 43, switch 46, valve 48 and squeeze rollers 15, 16 to throttle the air supply as desired. The expanded tube is then fed to moulds 24 for vacuum forming. The formed container 10 is then lowered by frame 19 as in Fig. 1, and the jaws 17, 18, 20, 21 are opened, raised and shut to sever the container 10, while a further container is formed (Figs. 2-4, not shown). Alternatively, the mechanical sensing mechanism may be replaced by photoelectric means (Fig. 5, not shown) which act similarly on valve 48 and squeeze-rollers 15, 16.

Abstract: 1427839 Capper chuck CHERRY-BURRELL CORP 19 Dec 1973 [3 Jan 1973] 58801/73 Heading B8T A capper chuck device for applying screw threaded closures to containers is mounted for movement around a closed path in a capping machine and comprises a pair of jaws 83, 85 which grip a closure 46 when an operating shaft 133 is lowered relative to a housing 67 resulting in the lower end 149 of the shaft 133 engaging a roller 151 on a toggle link 105. Due to the link 105 being pivotally connected through a jaw arm 115, to the jaw 85, as the link 105 is moved from a collapsed position (not shown) to which it is normally biased, to an over-centre position (Fig. 7), the jaws close in response, so gripping the closure 46. To apply the closure to a container a drive wheel 157 engages a friction plate as the chuck moves around the closed path (not shown). The drive wheel 157 rotates and causes the housing 67 and the jaws to rotate by virtue of a torque transfer arm 173 whose upper part engages a slot 181 in the drive wheel and whose lower part is attached to the housing. By lowering the chuck device the gripped closure is now applied to the container but as the closure tightens, the increasing torque tends to rotate the torque transfer arm 173 anti-clockwise against the force of the compression spring 187. When this force is overcome a shaft 175 rotates and a cam 203 abuts the roller 151 which forces the toggle link 105 back to its collapsed position and hence opens the jaws, so releasing the closure 46. The strength of the compression spring 187 and hence the tightening torque applied to the closure can be varied by adjusting a screw 199.
