Abstract: 1,257,011. Photochromism. BRITISH AIRCRAFT CORP. Ltd. 24 Jan., 1967 [27 Oct., 1965], No. 45518/65. Heading C4S. Optical apparatus, comprising means for focusing an image of a scene at an image plane and detecting means whereby the image may be viewed, has material which is transparent when subjected to radiation of lower intensity but which is rendered more absorptive when subjected to radiation of a higher intensity and which again becomes transparent when the higher intensity radiation is removed, placed at or near the image plane. By this means, the brightness of potential sources of glare within the field of view is reduced but the brightness of areas of low illumination remains unaffected. Objects may thus be viewed angularly closer to a bright source of illumination, e.g. the sun. The detecting means may be for example the eye using a subsidiary lens, a television camera, an image intensifier or an image converter. The glare reducing material may be a sheet of glass or other suitable carrier incorporating lightsensitive particles, e.g. photochromic glass. Binoculars incorporating sensitive glass in the manner outlined above could be used with spectacle frames by motorists to eliminate the hazard of dazzle caused by on-coming traffic.

Abstract: 1,265,554. Seals. ENGELHARD MIN. ERALS & CHEMICALS CORP. 20 June, 1969 [24 June, 1968], No. 31447/69. Heading B3V. [Also in Division C1] The interfaces of an article having at least.two interfaces, one of which: is glass or ceramic, and the other of which is glass, ceramic or metal, are sealed by a sealing layer which comprises or consists of palladium metal or a palladium alloy, the seal having an exposed portion so that, and the palladium being present in an amount such that, the seal may be broken -by exposure to hydrogen which converts the Pd from the alpha to the beta phase The layer may be of palladium or an alloy having an expansion characteristic in hydrogen similar to palladium, or the palladium or alloy may be dispersed in a fused inorganic non-metallic sealant layer, the layer preferably comprising over 60% by weight of palladium. Further layers of fused inorganic sealant may separate the palladium layer from one or both interfaces with the proviso that there must be present such a layer between the Pd-layer and a metal interface. These further layers may be of the same or different material as that in the palladium layer, and may be 0À0002-0À02 inch thick compared with 0À0001-0À001 inch thick for the palladium layer. The fused inorganic sealing layers may be of a conventional sealing material, examples of which are given, e.g. lead borate, glass, ceramic or glass containing ceramic or refractory material (e.g. zirconium diboride). The palladium alloy may be Pd-Cu, Pd-Pt, Pd-Rh, Pd-Ir, Pd-Os, Pd-Ag. The seal is formed by, for example, forming the Pd layer on an interface, forming a glass frit layer on the other -interface, assembling and firing, at, e.g. 600‹ C. for a glass sealant or 1000‹ C. for a ceramic. Alternatively, the parts can each first be fired before assembling. The seal is broken by exposing the seal to hydrogen (e.g. a 7% H 2 /93% N 2  gas), evidently by converting from the α- to the #-phase, and the seal breaks. The interfaces can be re-sealed if the parts are fired to reconvert the Pd to the α- form and re-assembled as before.

Abstract: 1,266,730. Inspecting fabrics. COURTAULDS Ltd. 9 Sept., 1970 [10 Sept., 1969], No. 44743/69. Heading D1S. Apparatus for marking faults during the inspection of a moving fabric 1 (or 21) comprises a movable marking device 4 (or 20), means for moving the marking device at substantially the same velocity as and in the same direction as the fabric, and operating means to cause the marking device to mark the fabric while so moving. In one embodiment, Fig. 1, the fabric 1 passes over an inspection table 2 having along one edge a guide rail 3 for a marking device 4 normally located (as shown) near the front of the table 2. An endless belt 5, chain, rope or cord is carried beneath the rail 3 by two pulleys 6 one of which is driven by a selsyn motor 8 through a belt and pulley drive 9, 10. The motor 8 is controlled by the fabric advancing roller driving system so that the speed of the belt 5 is substantially the same as that of the fabric 1. In operation, the rate at which the fabric moved is controlled by a foot pedal (not shown). On observing a fault, the operative presses a second foot pedal or a push button to energize an electromagnetic clamp 15 to connect the device to the upper run of the belt 5. Marking is carried out either by the operative actuating the device 4 or by arranging for marking to occur automatically a short time after the clamp 15 has been energized. After marking, the clamp 15 is deenergized either automatically a short time after completion of marking or when the device 4 trips a microswitch 18. A second electromagnetic clamp 16 is energized immediately to connect the device 4 to the lower run of the belt 5 to return it to its starting point at which a microswitch 17 is tripped to release the clamp 16. In another embodiment, Fig. 2, an endless belt 22 is mounted adjacent one selvedge of the fabric 21 and is driven at the same speed as the fabric 21. The outer surface of the belt 22 is provided with an absorbent pad 26 which is charged with ink from a reservoir 27 by a roller 28. A stationary platen 29 supports the fabric during operation of the marking device. In operation, upon detection of a fault in the fabric, a solenoid-operated presser 24 having a belt-engaging roller 25 is actuated to deflect the belt 22 so that it marks the fabric. If the apparatus is spaced lengthwise of the fabric from the inspection station, a time delay actuates the presser so that marking takes place at the correct point on the selvedge. In either of the two embodiments, the fabric may be scanned by a photo-electric device or by a closed-circuit television system arranged to generate a signal to actuate means for operating the marking device.
