Patent GB-1360992-A (GB)
Title: Papermaking
IPC: D21G9/00
Filed: 1970-10-21
Abstract: 1360992 Automatic control of position REED INTERNATIONAL Ltd 21 Oct 1971 [21 Oct 1970] 50028/70 Heading G3R [Also in Division G1] In a Fourdrinier type papermaking machine the position of the "dry-line", i.e. the boundary between wet and dry portions of the paper web, is detected by illuminating the appropriate area with visible or infrared light and monitoring the intensity of the resulting reflections. The intensity varies with the position of the boundary because the reflectance is specular from the wet surface and diffuse from the dry. The monitored signal may be used to control the position of the line. In an embodiment this is done firstly by adjusting the amount of suction in drying boxes, then, if this approaches limits, the dilution of the raw material is altered, and if this also approaches limits the refining process is modified Fig. 1 (not shown). Tube rolls and foils may also be adjusted to regulate the drying. A single photo-multiplier (2), Figs. 2, 3 (not shown) is arranged behind a lens system and shutter (3) which rotates at 1 r.p.s. to admit reflected and incident light from the source alternately, with a brief blanking period between each. A secondary shutter and associated light source and detectors (15, 16, 17) provides a discriminating signal, and the photo-multiplier can be slidably replaced by a mirror system (19, 20) for alignment purposes. The whole detector system is enclosed in a box 4 to which pressurized air is supplied and exhausted through vents which direct it across the lens surface. The signal from the photo-multiplier is connected through a buffer amplifier 21, Fig. 5, to a switch 22 which samples the 1 Hz signal at 10 KHz. This is operated by a multi-vibrator 23 operating at constant frequency but whose mark/space ratio is varied according to the difference between a voltage proportional to the signal corresponding to the light source and a reference voltage. By this means the signals emerging from the switch 22 are compensated for changes in lamp intensity and photo-multiplier sensitivity. These signals are integrated at 24 and separated into reflected and incident light signals respectively by a second switch 25 operated by the secondary shutter. The output circuit 26 and buffer amplifier 28 for the respective signals have long time constants to sustain the voltage during the respective "off" periods, and in the output circuit 26 during longer periods of accidental interruption of the light beam. This occurrence is detected by a separate threshold circuit, not shown, which stops switch 25 in the "off" (to 26) position. The circuits are fully described and component values given Figs. 6A, B (not shown). The switches comprise field effect transistors, which act as gates, filters are used to block noise, and signals are limited by Zener diodes for protection purposes.

An electro-photographic copying apparatus has guiding means for defining a path for a document to be copied, the guiding means including an adjustable deflector 310 for passing the document out of the machine or for recycling through an exposure station 33 for producing further copies. Feeding originals An original document to be copied is fed manually from a tray 354 through a slot 30 adjacent rollers 218, 219. Further rollers 236, 238 feed the document to a conveyer 248 which supports the document as it passes through exposure station 33. A guide 281 deflects the document towards rollers 290, 292 and deflector 310. The deflector (310) Fig. 3 (not shown) comprises a series of thin fingers (316) mounted on a common shift 318, Fig.2. When the fingers 316, Fig.2, are positioned in their dotted line position the document to be copied is recycled through the exposure station, and when in its full line position the document is delivered to a tray 312. A manually adjustable guide 322 removes skew from a document being recycled. The deflector 310 is controlled in its position by a solenoid 434 acting against a spring 454. The solenoid (434) Fig. 14 (not shown), is included in a control circuit having switches (450) and 578 controlled by a conventional stepper mechanism (562) Fig. 15 (not shown), having a selector dial (581) for setting the number of copies required from a single document. Exposing copy sheets Light is focused on imaging station 33, Fig. 2, by projection lamps e.g. 36. An image of the original to be copied is reflected by a mirror 38. Lens 40 projects the reflected image on to an electrostatically charged copy sheet passing through imaging station 28. Feeding copy sheets A stack 25 of photo-conductively coated copy sheets are fed singly from a compartment 24 by a belt 68 to feed rollers 65, 100 at the entrance to guides 121, 122. Rollers 124, 125 feed the copy sheet through corona charging unit 27. Developing electrostatic images The latent electrostatic image formed is developed by passage through a tank 44 containing liquid developer having charged particles opposite in polarity to the charge given by charging unit 27. A mechanism as described in Specification 43424/66 is provided for replenishing the supply of toner in response to the length of the original being fed. Fixing developed images Excess developer is removed from the copy sheet by rollers 46, 48, which may be connected to a low voltage supply which controls the density of the image and/or the cleanliness of the background. Fans 50 blow warm air from lamps e.g. 36 across the copy sheet to remove moisture. The developed and fined sheet is then discharged to a conveyer 49.
