Title: Web defect scanning
IPC: G01N21/89
Filed: 1976-03-11
Abstract: 1528001 Detecting web defects photoelectrically KODAK Ltd 11 March 1976 [13 March 1975] 10548/75 Heading G1A Web defect indicating apparatus comprises a repetitive line scanner 60, Fig. 6; means 64 responsive to radiation from the line scanner after interaction with a web 62; and means 68 for producing an audible signal having a frequency related to the scanning frequency. A typical waveform, Fig. 9 produced by apparatus transversely scanning a moving web includes: peaks 90, 92 corresponding to successive scannings of a flaw and having a spectrum envelope illustrated by the curve 100 of Fig. 10; coherent noise due to normal irregularities and having the waveform of the broken line 94 and a spectrum 104 lying substantially below the audible frequency limit 102; and random noise fluctuating about the coherent waveform and having a wide spectrum 106. A loudspeaker 68, Fig. 6 driven by an A.F. amplifier 66 coupled to the detector 64 eliminates a large portion of the random noise and produces a tone having a fundamental at the scanning frequency and a timbre from which the presence and type of a defect may be recognised. Coherent noise may be rejected by a function generator 65, Fig. 6 having positive and negative thresholds adjustable to just beyond the coherent noise peaks. If the web passes over a roller at the inspection point, dirt or flaws on the roller surface may be recognised by the presence of sidebands separated from the scanning frequency by the roller rotational frequency. A narrowband filter, centred on the scanning frequency or on one of its lower harmonics may be used. If the coherent noise level is high, the narrowband filter output may be averaged, a web flaw being recognisable as a temporary deviation from the average.  The scanning frequency may be in the high audio or ultrasonic range; a frequency divider may then be provided to respond to defect pulses at an audible sub-harmonic of the scanning frequency.

Title: Improvements in or relating to automatic sprinkler systems
IPC: A62C35/64
Filed: 1920-04-15
Abstract: 141,738. Lewis, L. M. April 16, 1919, [Convention date]. Sprinklers, automatic. - Relates to alarm-controlling apparatus for automatic sprinkler systems, of the type comprising an alarm check valve and means to allow for the escape of small quantities of water, thus preventing false alarms due to leakage, water hammer, &c. A passage 31 from the auxiliary valve of the alarm check valve 15 leads to a passage 30, pipes 45, 91, a restricted nozzle 93, Fig. 2, the hollow stem 76, 73 of a control valve 77, a fitting 64, a pipe 63, and past a normally open valve 58 to a drain pipe 62. The control valve 77 is normally held closed by the pressure of liquid in a supply pipe 94 acting upon the upper side of a diaphragm 71. When the alarm valve is operated by the opening of one or more sprinkler heads, the increased pressure in the pipes 45, 91, acting on a diaphragm 52 against the action of a spring 61, closes the drain valve 58. Pressure in a chamber 68 on the lower side of the diaphragm 71 then increases, until the control valve 77 opens and allows liquid to flow from the pipe 94 to a pipe 95 leading to the alarm. The auxiliary valve controlling the inlet to the passage 31, Figs. 1 and 4, is situated at the side of the main check valve 15 on a line passing through the centre of the valve 15 parallel to the axis of the pivot 21. The auxiliary valve consists of a disk which is lifted from its seat, on the opening of the valve 15 to a predetermined extent, by a flanged sleeve in which it is mounted and which is carried by a cross arm 36; this arm 36 is engaged by a lug 25 on the valve 15, and is secured to arms 41 turning about the pivot 21.

Title: Method and apparatus for resistance welding electrically-conducting tubular and flat parts together
IPC: B23K11/30
Filed: 1975-03-13
Abstract: 1504761 Resistance welding SOC ANON DES USINES CHAUSSON 13 March 1975 [20 March 1974] 10616/75 Heading B3R A method of resistance welding a tube 2 to a plate 1, e.g. a heat exchanger tube to a header box, so that an aperture 3 in the plate communicates with the inside of the tube, comprises the steps of placing one end of the tube 2 either around the aperture or into said aperture to form an electrical connection 7 between contacting portions thereof, inserting a first electrode 5 having a tapered head into the end of the tube to engage an oblique face 5a with the peripheral edge of the tube or aperture, placing a second electrode 4 either on the plate or tube in a location to provide an electric current path through the said contacting portions, passing an electric current between the electrodes 4, 5 to form a resistance weld, and being characterized in that at least one of the electrodes, e.g. the electrode 5, is movable so that the oblique wall 5a increases the pressure at the weld joint, the movement of the electrode being limited to a small distance by movement limiting means D so that initially the pressure ensures current flow to make the weld, but thereafter current flow drops. The end of the tube, or the edge of the aperture, may be roughened to increase the electrical resistance at the contacting portions. The second electrode 4 may grip the tube so that movement of the electrode moves the tube on to the tapered head of the electrode 5. The tapered head may include a ceramic centring piece 6. A flux may be used.

Title: Improvements in or relating to blades and guide blades for turbines, rotary compressors and the like
IPC: F01D5/14
Filed: 1942-07-30
Abstract: 568,575. Making turbine blades &c. CORBITT, R. W. July 30, 1942, No. 10681. [Classes 83 (ii) and 83 (iii)] [Also in Group XXVI] In a method of and apparatus for forming blades and guide blades for turbines, rotary compressors, &c., each blade surface is generated by a cutter which describes a conical surface whereof the apex lies beyond the blade tip and the cone axis is inclined to the radial blade axis so that a generator of the cone can occupy a position substantially parallel to the blade axis. Thus, a guide blade 10 of a centrifugal compressor rotates about an axis 12, Fig. 2, has a radial trailing edge 15 and the leading (concave) face is generated by a rotary cylindrical milling cutter 16 which describes part of a conical surface 18, 18a having an inclined axis 17 lying in a plane 19 transverse to the blade axis and containing the trailing edge. The blade faces are thus elliptical in crosssection, Fig. 2. The cutter may be fed radially or it may cut the entire blade surface in a single cut. The trailing face is similarly generated by a cutter 21 describing part of a conical surface 22, 22a having an axis 33. The apex angle of the cone 22 is less than that of cone 18 so that the blade increases in thickness from the leading edge 20 to the'trailing edge 15. Also the generators 18, 22 may diverge slightly towards the root of the blade to increase the root thickness. In the case of a turbine blade, Fig. 3, to provide a suitable entrance angle, the root section 27 is of greater axial length than the tip section 28. The trailing edge 29 lies in a plane transverse to the axis of rotation, but the edge tapers from 30 at the tip to 31 at the root. The axes of the generating cones both lie in the transverse plane 35. Instead of milling, the blade surfaces may be machined by any other suitable method.

Title: Improvements in charge forming devices for internal combustion engines
IPC: F02M69/04
Filed: 1936-04-14
Abstract: 472,184. Oil engines. BUCHI, A. April 14, 1936, No. 10682. Convention date, April 14, 1935. [Class 7 (iii)] In an engine operating with sparking-plug ignition of the mixture, and admission of the fuel by injection means controlled in timed relation with the expansion strokes, the charge being precompressed and the cylinder scavenged, a heat exchanger is disposed ahead of the inlet valve between that valve and the fuel injection means to heat the fuel and vaporize, or even in part, gasefy, it by the heat absorbed, during the combustion period, by the working cylinder, the cylinder head or both, with or without waste heat from the exhaust gases. A motor 6 driven by the exhaust gases drives a compressor 7 which forces air through the inlet manifold 8 past the inlet valve 10 to the cylinder. An injector 11 sprays fuel into the inlet passage and the fuel is vaporized, by passage through a heater 17 surrounded by a jacket through which the cooling water or exhaust gases flow or receiving heat by conduction from the cylinder head. As shown, a valve 24 in the main return pipe of the cooling system may be closed or opened to direct more or less water through the heater jacket which byepasses it, but if exhaust gases are used, the valve is disposed directly in the supply passage therefor. A helical blade 25 in the heater assists in mixing the fuel and air.

Title: Improvements in Processes for the Extraction of Lead from its Ores.
Inventor: ELMORE FRANK EDWARD
Filed: 1918-07-06
Abstract: 129,773. Elmore, F. E. July 0, 1918. Lead chloride and sulphate.-In processes in which lead sulphate is extracted from ore products by brine or brine and sulphuric acid and subsequently separated from the solution as in the process described in Specification 127,641, the accumulation of sodium sulphate in the brine is liable to interfere with the process. To regenerate the brine which has thus lost its efficiency, the solution is cooled to about 0 C., either before or after the separation of the lead salts. In the former case, lead salts and sodium sulphate separate out, and, after removal from the brine, which is then fit for use again, the mixture of salts is treated with hot, preferably boiling, water, whereby lead sulphate and brine are obtained; in the latter case, the sodium sulphate which separates is dissolved in hot water and used to treat the lead salts first separated, so as to obtain lead sulphate and brine as before, the treatment being preferably effected in a series of vessels on the countercurrent principle. If silver is present, the lead salts may be boiled with water to extract lead chloride, the silver remaining with the residual lead sulphate, and the lead chloride is converted into sulphate by the sodium sulphate obtained as above described.
