Title: Signal presence detectors
IPC: H04L1/20
Filed: 1971-12-16
Abstract: 1391456 Digital transmission; detecting signals in the presence of noise MARCONI CO Ltd 1 Sept 1972 [16 Dec 1971] 58579/71 Heading H4P To detect signals in the presence of noise one of two bandpass filters has a range including signal frequencies and a parallel bandpass filter excludes such range, the filter outputs being combined and fed to a device determining the mean frequency and which provides an indication of the relativity of signal to noise. In a simple embodiment (Fig. 1, not shown), signals, and noise at signal frequency, is passed by filter (2) and noise at a lower frequency by filter (3), outputs being combined at (4) which may be a summing amplifier, the combined output which is dependent on the frequency and relative amplitudes of signal and noise is applied to a timed counter (5) which gives an indication over lead (6) of the average frequency. When there is no noise counter (5) will indicate signal frequency and when there is noise but no signal the counter will measure the frequency of such noise, hence counter output will give an indication of the signal/noise ratio and a threshold will provide a minimum acceptable level. In an FSK system utilizing 2 tones, signals are passed to filters 9, 10 tuned to the tones and filter 8 tuned to a lower frequency, the band width being the same, e.g. 310 Hz, in each filter. Differing band widths could be utilized with adjustable attenuators in the outputs of equalize amplitude levels. Mark tones are passed by 9 and combined at 11  whereas space signals are passed by 10 and combined at 12, respective outputs being applied to Schmidt trigger circuits 13, 14 and timed counters 15, 16, outputs from which operate OR gate 20 and monostable circuit 21 thus operating a relay 23 closing contacts 24 permitting signals delayed by say 1À7 sec. by unit 25 to pass to teleprinter 26. Further contacts (not shown), may energize a visual indication means.

Abstract: 1381580 Automatic control of web tension NISHIMURA SEISAKUSHO CO Ltd and FUJI XEROX CO Ltd 29 Dec 1971 [28 Dec 1970] 60439/71 Heading G3R [Also in Division B8] Apparatus for intermittently processing (e.g. cutting) a web of material 12 is operated to perform one cycle when a detector (lamp LA and photo-cell PS) determines that a loop 50 in the web feed has reached a lower limit. The web is normally fed continuously by roller 10 but if the signal from detector PS persists for a pre-set time the supply to roller drive motor SM is interrupted until the loop clears the detector. Normally, the signal from PS is applied via logic circuits Fig. 3 (not shown) to energize an electromagnet SO, thus lowering pinch roller 26 and causing the web to be advanced by roller 24 which is continuously driven by motor DM via flywheel 28. Marks on the web are detected photo-electrically at PD and start a timer comprising an RC circuit and a Schmitt trigger which operates a clutch CL and releases a brake BR allowing the motor DM to operate a cutting blade 36 via crank mechanism 34 ... 44. Simultaneously the electromagnet SO is released to stop the feed. A cam operated switch PX releases the clutch and applies the brake after each cut. The timer is supplied with a voltage from a tachogenerator TG so that the cut occurs at the same point (set by varying R in the RC circuit) relative to the mark regardless of the feed speed, which is manually adjustable.

IPC: C23C10/22
Filed: 1968-12-24
Abstract: 1,246,498. Heat treatment of alloy coated metal articles. E.I. DU PONT DE NEMOURS & CO. Dec. 24, 1968 [Dec. 27, 1967], No.61489/68. Headings C7F and C7N An alloy coated metal substrate is heat treated in a melt comprising a molten metal transfer agent such as Ca, Ba, Sr, at a temperature between 900‹ C. and the substrate melting point for a time to allow carbon to migrate into the melt without allowing further alloying, and then quenching. Heat treating may be effected by dipping in the fused bath containing 10-99% Ca, Ba or Sr preferably at least 50% or by coating with a solidified melt such as drag out from the coating bath and then heating in a non oxidizing or inert atmosphere to fuse the solidified melt. The melt in addition to Ca, Ba or Sr may contain diluents such as Cu, Pb, Sn and the nitride of Ca, Ba or Sr and also diffusion elements such as Cr, Ni, Mn, Co, Zn, Mo, Nb, Si, Al. The melt containing the diffusion elements may have been used to form the initial alloy coating but retreatment time in this melt is insufficient to allow further alloying e. g. 60-120 secs. at 925- 1000‹ C. or 10-30 secs. 1000-1100‹ C. The quenching may be effected in liquid Na optionally containing K, Cs or Rb, or in a liquid comprising a hydrocarbon, silicone oil, water or brine, or in a gas or fluidized bed. The examples relate to the coating of steel substrates in a molten bath containing Ca, Ni, Al and Cr to form an alloy coating containing 26% Cr, 3% Ni, 0À3% Al. The coated articles are then heat treated in the same bath, both coating and heat treating being effected in an inert atmosphere. Alternatively the coating may be by a gas diffusion process. The heat treatment removes stains, increases the corrosion resistance and reduces the "orange peel" effect on deformation.
