Title: System for automatically detecting defects in a moving sheet
IPC: G01N21/89
Filed: 1968-01-15
Abstract: 1,204,951. Circuit assemblies. TATEISI ELECTRONICS CO. 15 Jan., 1968 [16 Jan., 1967], No. 2101/68. Heading H1R. [Also in Division G1] Flaws, stains, marks or holes in a moving sheet of cloth, paper &c. are detected by photoelectrics apparatus comprising an array of detection units arranged across the width of the moving sheet. Each unit comprises a number of photo-cells (3), Fig. 3 (not shown), each receiving light reflected from or transmitted through the sheet, and being connected to a respective amplifier (4) and, Schmitt trigger circuit (5), the triggering level for the latter being set to that of an inadmissible defect in the sheet. The Schmitt triggers (5) in each unit are connected to a common OR circuit (7A) also, forming part of the unit, Fig. 3 (not shown). The OR-circuit of each unit can be connected to an indicator lamp (9) Figs. 4, 5 (not shown). Alternatively, all the OR=circuits of the units are connected to a control circuit which comprises an input OR-circuit (7) connected to the output OR-circuits of the units and means to cause operation of a recording device or a sheet marker controlled by circuit (24). The adjustment of the levels of the Schmitt triggers of a detection unit may be by individual variable resistances associated with each trigger circuit, or more conveniently by a common control potentiometer operating on differential amplifiers connected between each amplifier and trigger circuit. Facility for calibration of these levels with perfect sheets or sheets having known defects is provided and methods of calibration described with reference to Figs. 4, 5 (not shown). The construction of photo-electric apparatus, suitable for, examination by reflected light is described, Figs. 6 and 7-9 (not shown) and features separate casings for the light sources and the detection units, which are adjustably mounted for different heights and angles with respect to the moving sheet so as to allow for differences in thickness &c. of sheets examined. The casing for the light sources has a narrow passage for directing light on to the sheet, Fig. 9 (not shown). The detection unit comprises a box carrying the photo-electric elements which is attached by a plug-and-socket coupling to a box carrying the amplifiers, Schmitt trigger circuits and common OR-circuit (and if necessary differential amplifiers). The unitary construction and mounting of amplifier circuitry near to the measuring station allows for variation of the width of the detection arrangement with differing widths of material, and for the leads between photo-cells and associated amplifiers to be short, so as to reduce noise picked up by the leads. Also one particular part of the sheet can be tested with more accuracy than the rest.

Abstract: 328,258. Robinson, J. Jan. 22, 1929. Charging; covers.-In an installation comprising a plurality of cupola furnaces arranged in line and having an overhead track for a charge-container extending from one end of the line to the other, the container, on being brought to rest by an operator above any desired furnace, is adapted automatically to open the furnace cover, and on moving away after discharge to cause the cover automatically to close again. Fig. 4 shows a construction in which a charging bucket 1, travelling on an overhead runway 3 is formed with trunnions 4 adapted, as the bucket is lowered on to the furnace 16 to be charged, to engage in supports 25 provided on a floating chair 18. The latter carries counterweights 22 and is guided on pillars 19 on one of which is loosely mounted a helical member 27 secured to an arm carrying the furnace cover 26. A fitting 28 secured to the chair 18 is adapted, as the chair is pressed downwardly by the continued descent of the bucket 1, to rotate the member 27 and so swing the cover 26 horizontally to open the furnace. As the bucket is raised, after discharge, the upward movement of the chair under the action of the counterweights 22 returns the cover to closed position. In a modification, the cover 26 is mounted on wheels and is moved to one side on rails as the chair 18 descends, counterweights being provided to return the cover to closed position when the bucket is lifted after discharge. Further constructions are described in which the cover 26 is formed in two pivoted halves adapted to open downwardly or upwardly as the chair 18 descends and close again as the bucket 1 is withdrawn. Fig. 14 shows a modified form of apparatus in which the chair 18 is omitted, the cover 90 being swung horizontally to the open position by the engagement of a rack 71, mounted on the trolly carrying the bucket 1, with a fixed pinion 78 adapted to operate, the cover through a chain 83 passing over sheaves 82, 85, 91 and attached to a counterweight 92. The rack 71, in its normal position, clears the pinions 78 but is raised to engage the pinion corresponding to the furnace to be charged by linkwork 75, 76 operated by a handle 77. The bucket 1 is formed, as shown in Fig. 1, with pivoted discharge doors 5 carried by straps 7 which are pivoted at 10 to a block 8, the latter being normally held in raised position by a hooked arm 14 which, as the bucket is lowered on to the furnace mouth, strikes a fixed projection and rotates about its pivot 13 to release the doors 5.

In a metal spraying pistol two continuously advancing metal wires 24, 25 are connected to an electric current source and meet at a point K, Fig. 1, in front of the pistol where they are continuously shortcircuited, their ends melted thereby, and the molten metal is sprayed on to a surface &c. by a compressed air jet flowing through the nozzle head 32. The pistol comprises a housing 10 for wire feed rollers 12-15, the rollers 12, 13 having worm wheels 16, 17 driven by a worm 18 which is driven by a flexible shaft 19. The latter is preferably driven by an electric motor. Rollers 14, 15 are secured to a hinged cover 11 and the pressure between the roller pairs is adjusted by springs 28, 29. The wires are fed into guiding sleeves 30, 31 which support bending rollers 37 and guide rollers 38, 39 within the nozzle head, and the wires pass through guiding nozzles 35, 36. The bending and guide rollers and the associated nozzle for each wire are formed as a unit which is angularly adjustable so that the distance of the wire contact point from the front of the pistol may be varied. Electric supply connectors 43, 44 are secured to the guiding sleeves 30, 31 and current is supplied to the wires mainly through the bending and guide rollers. Wire cleaning chambers may be arranged at the entrance end of the guiding sleeves. Compressed air is delivered to a passage 49 and flows into a chamber 50 and through perforations 51 to the nozzle head. An annular air jet concentric with the main jet may be provided, and for this purpose a tubular member supplied with compressed air may be secured to the front of the nozzle head, said head being secured to the housing by a bayonet joint. In Fig. 11 the wires are fed at an acute angle through a casing 10 so that wire bending is obviated. Feeding rollers 101, 102 are driven via separate worms 105, 106 connected to flexible shafts 107, 108. In Fig. 12 the two wires are fed in straight lines up to the contact point by a common driving shaft 201 and gearing, and compressed atomizing air fed at 202 flows along the wire 25 only. Instead of rollers the current supply to the wires may comprise a link chain 401, Fig. 14, which is recessed to conform to the wire shape and co-operates with toothed chain driving wheels 402. The electric supply to the wires is automatically cut off if the compressed air supply fails and preferably also if the supply to the electric motor driving the feed rollers is interrupted.
