摘要： A fault seeking apparatus for detecting faults in carpet webs (15) has a first main mirror wheel (17) which is illuminated by a laser beam (18) and which generates via a concave mirror (13), a scanning beam (14) which is periodically displaced parallel to itself. This scanning beam is directed at an angle to several subsidiary mirror wheels (11a to 11i) which are arranged alongside one another, which rotate substantially faster than the main mirror wheel (17) and which generate a scanning light strip on the carpet web (15). A light receiving device consisting of lenses (20a to 20i) arranged alongside one another and a light conducting rod (22) with a photomultiplier (23) at one end face is arranged on the other side of the carpet web (15) (FIG. 1).

摘要： Hole seeking apparatus for material webs is disclosed which features a light source for projecting a light beam onto a mirror wheel arrangement located optically in front of a concave mirror so as to produce a scanning beam in the image space of the concave mirror. The scanning beam is continuously displaced parallel to itself so as to periodically scan along a scanning path on the material web. The mirror wheel arrangement consists of two substantially identical mirror wheels which lie coaxially on one another and which are displaced by a half pitch.The dimensions of the light bead at its point of incidence on the mirror wheels and the optical geometry of the apparatus are selected to avoid light being scattered at an edge of either of the mirror wheels and passing to either side of the web. Scattered light is thus prevented from falling on a light receiving device arranged behind the web and intended to detect the presence of holes therein. In this way the false recognition of a hole at the margins of the web is prevented.

摘要： Apparatus for combining light emanating from a linear scanning field on a relatively small receiver via an optical arrangement producing a scanning light spot with a light ray scanning device onto which a light beam impinges, the arrangement further having optical elements of the transmitting beam of rays located in front of the light ray scanning device, a transmitting concave mirror and a receiving concave mirror extending in the scanning direction, and a cylindrical lens parallel to the scanning field and extending in the vicinity of the latter, the transmitting and receiving beams of rays being separated by pupil separation. There is further provided plane mirrors arranged between the concave mirrors and light ray scanning device for bending the receiving beam of rays perpendicular to the scanning direction and in the direction of the intersection point of the optical axis of the transmitting beam of rays located on the light ray scanning device by such an amount that it still strikes the light ray scanning device, but passes beside the optical elements. The curved surface of the cylindrical lens is ground planar in the area of the entry of the transmitting beam of rays, and the receiving concave mirror is displaced relative to the transmitting concave mirror in the sense of shortening the optical path of the receiving light.

摘要： A hydroculture has a feed solution tank 11 from which feed solution is supplied to the plant roots by capillary action or pump action. Feed tubes 12 of a hydrophobic microporous material which is water vapor permeable but not water permeable are laid in this feed solution tank 11, and salt water having a substantially elevated temperature relative to the feed solution is led through the feed tube 12. In this way the used-up feed solution is replaced by desalinated water.

摘要： An optical fault seeking apparatus has a light scanning apparatus (21) and a light line receiving apparatus (14) which receive the light reflected from the material to be investigated and direct it onto a photoelectric converter. The light beam which forms the light line 11 impinges at an acute angle (.alpha.) onto the surface (13) of the article or web (18) under investigation. The image forming optical light line receiving apparatus (14), effectively consists of two light receivers (14, 14') positioned away from the normally reflected beam (23) and arranged to receive light from respective ones of two spaced apart strip-like regions (11', 11") extending parallel to and partly overlapping the line of light (11). In this way the device is able to detect faults (e.g. lumps or depressions) in fleece-type webs with irregular surface structures which are normally very difficult to monitor with optical fault seeking apparatus (FIG. 1).

摘要： A fault detecting apparatus for flat articles generates a line of light on the article which is imaged onto a photoreceiver via an optical system having cylindrical imaging characteristics. For use with an article 11 having light diffracting characteristics the line of light 12 is arranged substantially at right angles to the structure 13 which causes the light diffraction. The optical system 14 having cylindrical imaging characteristics detects, apart from the zero order at least also the first diffraction order of the light leaving the article. The light of the first diffraction order is also imaged onto its own photoreceiver (FIG. 1).

摘要： Apparatus for monitoring for faults in translucent strip material, such as photographic film, comprises a transport device 16, 12, 13, 22 for continuously moving the film 11 in its longitudinal direction and an optical scanning device 23 including a beam divider 21 which divides a single series of scanned light beams 14 into first and second sets of scanned light beams 14a 14b. The first set of light beams 14a is used to carry out transmission measurements on the film as it passes in tensioned condition between two spaced apart rollers 12, 13 and the second set 14b is used to carry out measurements in reflection as the film passes around the surface of a roller 16. The roller 16 has an air permeable surface and air is blown through this surface from the inside of the roller to form an air cushion between the film and the roller.Faults are detected by the electronic processing circuitry 18 in response to variations in the transmission and reflection measurements carried out by the light detectors 15 and 17.

摘要： A banknote condition monitoring apparatus features a mirror wheel (22) located substantially at the focus of a concave mirror strip (25) with an intervening plane mirror (26) to fold the beam path. The mirror wheel (22) scans an incident light beam from a source (28) to form a transmitted light beam in the image space of the concave mirror (25) which is continuously displaced parallel to itself to and fro through the image space. The transmitted light beam is directed via a cylindrical lens (14) onto the surface of a drum (11) carrying the banknotes (12) to be monitored on its peripheral surface by way of air suction via the channels (32). Light remitted from the surface of the banknote is directed through the lower half of the cylindrical lens (14), impinges on a light conducting rod (15) and is detected at an and face of the light conducting rod by a light receiving device (33). The mean output signal from this light receiving device indicates the presence of holed, torn or dog-eared or dirty banknotes but not strips of clear adhesive film which are recognized by the specularly reflected light beam (21) which falls on a stationary photodetector (23). The optical distance of the stationary detector (23) from the drum is equal to that of the mirror wheel scanning device so that the specularly reflected light beam always passes through a stationary point in space.
