Title: Frequency tracking filter
IPC: H03G5/16
Filed: 1974-06-06
Abstract: 1432432 Automatic tuning STANDARD TELEPHONES & CABLES Ltd 6 June 1974 25089/74 Heading H3A In a frequency tracking filter of the kind described in Specification 1,432,431 verification is needed that the signal being tracked is the described signal and not the multipath signal. At maximum range random noise may be identified as a strong persistent signal whereby verification on the basis of amplitude of the tracked signal may give incorrect results. The filter therefore comprises means responsive to the signal not being tracked being uniformly distributed over the band of the filter to give a zero output and to the signal not being tracked being comprised of a single frequency to give an output indicating the amplitude of the single frequency, means comparing the amplitude of the tracked signal with the said output to bring about reacquisition if said output is greater than said tracked signal amplitude. The filter therefore comprises a phase detector 3 receiving the input signal 1 via a 90 degree phase shifter 2 and via a tunable resonant circuit LCR. The output of the detector 3 serves as explained in said Specification 1,432,431 to adjust capacitor C and cause the filter to track. The "within band" signal from the filter is also detected at 4 to give a negative signal, whilst the "off-tune" signal across resistor R is detected via a circuit 8, 7, 9, 10, 11 at 5 to give a positive signal. This is combined or compared with the negative signal to give an output which sets or resets a bistable circuit 6 such that, if necessary, a damping resistor r is added to the circuit LCR to bring about the reacquisition. The signal at P, i.e. noise, extending uniformly from f 1  to f 2 , or a signle frequency within said range, is mixed at 7 with a local oscillator (8) output F and the sum beat fed through a band pass/delay network 9 having a delay equal to 1/(f 2  -f 1 ). This gives a linear phase shift of 2# over the range F +f 1  to F+f 2 . The phase shifted signal(s) are transferred to a common frequency F by a second mixing process at 10 using the difference beat and a filter 11 tuned to F. A uniformly distributed noise signal has its components phase shifted by all angles in network 9 such that the sum output at F is zero. A single frequency will produce a discrete output at F.

Title: High efficiency plasma process head
IPC: H05H1/50
Filed: 1966-06-07
Abstract: 1,130,600. Plasma arc apparatus. MHD RESEARCH Inc. 7 June, 1966 [14 June, 1965], No. 25341/66. Heading H5H. [Also in Division C5] Plasma processing apparatus includes coaxial hollow anode and cathode elements 10, 11, with passages 12, 13 for passing a flow of gas therethrough and for reception of an arc discharge pattern penetrating the electrodes in the path of the flow. A gas ring 16 provides inlet ports (17), (Fig. 3, not shown), to receive gas from a duct 22 via a plenum (22a) to direct the inlet flow in a spiral or vortex within a plenum 18 between the electrode terminal flanges 19 and 20. The vortex flow divides at locus 21 and enters throat regions 12a and 13a of passages 12 and 13. Coolant fluid enters passages 32, 34, via ducts 38, 39, circulates round passages 33, 35, and exits via ducts 40, 41. There is produced a gas unstabilized arc at points of variable arc attachment to the electrodes (see Fig. 2, not shown), due to the vortex or rotating character of the gas flow. Downstream valves 71-73 are adjustable to provide turbulent flow conditions or magnetic field producing coils (120) or (128), (129), are energizable to rotate the points of arc attachment (Figs. 7, 8, not shown). Quench fluid is introduced into the path of the hot gas flowing downstream of the points of arc attachment via bodies 48, 49, forming plenum chambers 54, 55, to which quench fluid is supplied via ducts 56, 57. The fluid then passes via ports 58, 59 into the gas at regions 60, 61, and sharply reduces the gas temperature to aid in terminating chemical reactions occurring therein. Natural gas may be fed in to produce acetylene, or particulate material such as iron ore may be injected via ducting (80), (Fig. 3, not shown), at a point downstream of the flow division locus 21, to produce a product of desired metallurgical properties.
