Title: Optical detection apparatus
IPC: G01N33/46
Filed: 1974-01-18
Abstract: 1488841 Detecting knots in timber PLESSEY CO Ltd 8 Jan 1975 [18 Jan 1974] 02472/74 Heading G1A In an apparatus for detecting knots in timber 1 radiation from a source 2 is directed into the timber 1 so that it travels inside the timber 1 along the grain, and the radiation emerging a predetermined distance away is received by a detector 4 connected to a threshold detector 7. A defect such as a knot will severely attenuate the radiation reaching the detector 4. An opaque barrier 3 prevents the detector 4 from being directly illuminated. A number of these apparatuses may be placed over an inspection gate through which the timber passes, alternatively Fig 2b (not shown), a row of photo-diodes may be arranged on one side of the opaque barrier to receive a strip image of the wood, the photo-diode array being scanned electronically. In Fig. 3a, a He Ne laser transmits a beam of light via an apertured mirror 26, and a mirror 25 on to the wood's surface 21. A detector, or detector array 28 is positioned so as to receive radiation via lens 27 and mirrors 25 and 26 from a position spaced from the incident spot of light. Light filters may be included to exclude ambient light and the mirror 25 is arranged to be rotatable or deflectable so that the wood can be scanned. In a modification Fig. 4 (not shown) of the above, Fig. 3a, two further detectors are utilized, one positioned to receive radiation from the incident spot of light the other positioned to receive radiation that has passed across the grain. By comparing the last mentioned detector's output, the knots can be detected because normally the detector 28's output would be much greater. Additional information about the nature of the defect can be obtained by two further detectors, one behind a red filter, the other behind a blue filter. These detectors receive radiation that has been reflected off the wood from the flood light 29. If the blue signal is stronger compared to the red, a stain or rot is indicated. A block circuit diagram Fig. 5 (not shown) for processing the above types of detector outputs is disclosed. The description refers to employing a computer with a memory or store to enable a defect and consequently its shape or configuration to be detected.

Title: Daylight fluorescent compositions and pigments for use in same
IPC: C09K11/06
Filed: 1959-01-26
Abstract: A daylight fluorescent dyestuff is incorporated into a base formed from an aryl sulphonamide, benzoguanamine and an aldehyde, the benzoguanamine being present in a smaller amount by weight than the aryl sulphonamide.  Suitable sulphonamides are benzene, p- or mixed o- and p-toluene, or naphthalene-sulphonamide. Suitable aldehydes are formaldehyde, benzaldehyde, glyoxal, pyruvic aldehyde and acetaldehyde.  If desired each nitrogen-containing compound can first be reacted with aldehyde before combination of the two condensates. In Examples (1) benzoguanamine is dissolved in molten toluene sulphonamide resin. Rhodamine BX, Rhodamine 7G and Brilliant Yellow 6G base are added, the batch cooled to 240 DEG F. and paraformaldehyde added. The temperature is again raised and the molten mixture solidified; (2) The resin of Example 1 was mixed with butyl carbitol acetate dried silica gel and a fluorescent dye in a polyvalent metal-alkyd resin complex as produced in French Specification 1,064,958 to form a letterpress ink; (3) and (4) are similar to (1), the final products being ground to form a pigment. In Example (5) the pigments of Examples (3), (4) are compounded with a polyacrylic resin to give a silk screen lacquer.  Other examples are similar. Canadian Specification 562,729 and U.S.A. Specification 2,809,954 also are referred to.
