Title: Measuring current in welding machines
IPC: G01R15/18
Filed: 1981-07-02
Abstract: Sensor leads for monitoring weld nugget resistance are connected to the electrodes or to the welding current conductors, the voltage component induced in the sensor leads due to inductive coupling is cancelled out by inducting a substantially equal and opposite leads. For this purpose an inductance coil may be connected into one of the sensor leads and appropriately positioned on one of the welding current conductors. A core-less coil can be employed, and correct adjustment of the compensating voltage can be achieved by adjusting the coil angularly with respect to the axis of the welding current conductor. Alternatively, the sensor leads may be positionally interchanged with respect to each other at a point half-way along the supply conductors, so that opposing voltages are induced in each half. <IMAGE>

Patent GB-2091458-A (GB)
Title: Swept Frequency Oscillators
IPC: H03B23/00
Filed: 1981-12-07
Abstract: A swept frequency oscillator 1 is capable of providing an output signal whose frequency can be swept over a very wide range at a rate which is not dictated by the period of the lowest frequency in the range. The signal detector 4-6 monitors the output level of the oscillator so as to generate a control signal to remove variations in the output power level. At frequencies below a particular value, the time constant of the detector is modified progressively so as to be inversely proportional to the frequency being generated. Thus at low frequencies in the swept frequency range. the time constant of the detector is increased. Hence, at frequencies below the 1 MHz cut-off of low-pass filter 25, Schmitt trigger 26 is operative to cause monostable 27 to produce pulses at the signal rate for discharging capacitor 5 through resistor 7 and diode 9. At frequencies above the 500 KHz cut-off of high- pass filter 18, comparator 22 is operative to render diode 8 conductive, and the total time- constant is substantially constant. Variations with frequency in the voltage drop across resistor 6 and diode 4 are corrected by resistor 14 which produces a corresponding current through feedback resistor 13 and diode 12 across a unitary-gain amplifier 11. <IMAGE>

Title: Gas cylinder fitting
Inventor: NEWMAN GRAHAM
IPC: B01F3/04
Filed: 1982-12-14
Abstract: A fitting for use in making a gas- tight connection to a gas cylinder, which has an externally screw- threaded neck 14 with a sealing disc 15, has a tubular housing 1 into which the neck 14 is screwed. To form a seal, a member 5 is slidable and rotatable in the housing and carries an O-ring 20. As the neck 14 is screwed into the housing 1, the member 5 is pressed back against the action of a spring 7 and a fixed tubular piercer 16 pierces the disc 15. Gas under pressure from the cylinder then flows through the piercer 16 and thence through a valve 30 in an adapter 2 which is fixed to the housing 1. Further gas flows around the outside of the piercer 16 into a space 21 and its pressure assists the spring 7 in pressing the O-ring 20 against the end face of the neck 14. The member 5 with the O-ring 20 rotate in the housing 1 as the neck 14 is screwed in and in this way wear of the O-ring 20 by rubbing against the end face of the neck is prevented. <IMAGE>
