Title: Improvements in or relating to radiation plant
IPC: G21K5/10
Filed: 1959-07-06
Abstract: 869,267. Radiation generators. BROWN, BOVERI & CIE A.G. July 6, 1959 [July 4, 1958], No. 23109/59. Class 98(1) [Also in Group XXXV] A radiation generator 1 is mounted over a treatment bed 4, the generator being rotatable about a horizontal axis, and also adjustable vertically by a servomotor; the bed is on a chassis 3 displaceable along a horizontal track; the generator is linked to the bed by an arm 15, and as it rotates, and the chassis consequently traverses along the track, any tendency for vertical movement of the bed and chassis is arranged to produce corresponding control signals which are passed to the servomotor which produces compensating vertical movement of the generator so that vertical movement of the bed is minimized. The generator pivots on an axis 7, and oscillates about this axis at a regular angular speed under the action of a motor 10. The generator is supported on a vertical column 8 which can be raised or lowered by a servomotor 11. The generator 1 is linked to the chassis by an arm 15 pivoting at 16 (and which is adjustable in length), so that as the generator oscillates, and the chassis traverses back and forth on spring-supported wheels 6 (Fig. 2, not shown), there is a tendency for the latter to be pulled upwards or pushed downwards. This is sensed by a roller 20 on the chassis, the roller being mounted on a vertical rack 21 and bearing against the track. The rack engages with a gear wheel 22 carrying the arm of a regulating resistor 23. Upward or downward movement of the roller, and therefore the rack, causes a displacement of the resistor arm, which sends. a signal through an amplifier 19 to the servomotor 11, which then acts to raise or lower the column 8 and generator 1 so as to oppose the tendency to vertical movement of the chassis.

Abstract: 1,114,202. Control systems for stud-welding apparatus. CROMPTON PARKINSON Ltd. 2 June, 1965 [5 June, 1964], No. 23539/65. Heading H2H. [Also in Division B3] Electric arc stud-welding equipment comprises a tool 10, having a lifting coil 52 for retracting a stud 20 from a workpiece against the effect of a spring 50 so as to strike a pilot arc, the spring 50 returning the stud 20 to the workpiece when the coil is de-energized, and a controller which includes a timing device circuit for energizing the lifting coil and a timing device circuit for supplying welding current from a storage capacitor to the arc while the stud is retracted, each being capable of independent adjustment so as to vary the relative times of initiation of the return movement of the stud and the start of the supply of welding current. The timing device for starting the welding arc may itself be started by the timing device for energizing the lifting coil or the two independently adjustable timing devices may be started simultaneously. The controller may also include a third adjustable timing device for starting the other two devices. In this way the welding arc may be started after the stud starts to move towards the workpiece or it may be started at the same time as or before the stud starts to move. The controller may include a safety circuit which automatically shuts-off the power if the voltage across the stud and workpiece exceeds a predetermined value. The welding arc is achieved by charging the storage capacitor (58) (Fig. 2, not shown), which discharges through a silicon controlled rectifier (SCR1) to the stud 20 and workpiece (60). The timing devices have variable resistors controlling the rate of charge of capacitors which, on discharging, give pulses which operate relays and unijunction transistors to control the sequence of operations.

Abstract: 1,019,034. Covering cores by winding. PIRELLI S.p.A. June 14, 1963 [June 20, 1962], No. 23737/63. Heading B8G. [Also in Division B7]  A structure comprising a single or multistranded filament helically wound about an axis which extends along a pitch circle, which may be used as a bead core for a tyre, is made by securing one end of the filament 1 to a point on the periphery of a flexible ring-like core 27 and rotating the core 27 about its axis of symmetry simultaneously with rotating its periphery about its own circumferentially. extending axis, so as to wind the filament on to the core, after which the core is split at one point and removed from the wound annular structure. As shown, wire 1 is fed from a bobbin 2, its free end being clamped by a cylinder 11 on a carriage 10, which carriage moves to carry the wire end to where it is attached to core 27. The clamp is released and carriage 10 retracted. The core 27 is held by four sets of rollers 24, 25, 26, spaced around a revolving platform 21 (Fig. 2, not shown), and as the platform rotates the rollers are all driven to give the core 27 the desired movement. Each roller 26 is retractable by linkages 28, 29, 30 all actuated by a cylinder 33 to facilitate removal of the core. The cylinder 33 rotates with the platform 21, which is driven by a motor engaging gear 23. When winding is completed, a knife 19 cuts off the wire, whose end is again clamped by cylinder 11, and the two ends of wire on the core are butt joined, using a ferrule. During winding the arm 3 carrying bobbin 2 is rotated about a vertical axis to twist the wire in the opposite sense to the twist it receives when applied to the core. As wire builds up on the core, the platform rotation speed is altered after each revolution to compensate for the increased thickness of the " core." " In making bead wires, the helices are of such pitch that turns produced in successive revolutions of the platform are laid side by side on the core. Alternate sections of core may be covered by these adjacent turns while intermediate sections remain bare.

Filed: 1944-12-04
Abstract: In the manufacture of steel or iron by the Bessemer process, a mixture of carbon dioxide with oxygen alone, or air enriched with oxygen, is used during the whole or part of the blowing operation. The oxidizing gas may contain 30-80 per cent. of carbon dioxide, the remainder being oxygen which should contain no more than 4 per cent. of nitrogen.  Air may be used for blowing at the commencement of the operation and, depending on the amount of nitrogen it is desired to leave in the iron or steel, the change to the mixture of carbon dioxide and oxygen is made after a shorter or a longer time.  The temperature of the melt may be controlled by varying the amount of carbon dioxide in the oxydizing gas or by blowing with the gas mixture intermittently during the operation.
