Patent GB-1307397-A (GB)
Title: Method and apparatus for inspecting webs of photosensitive materials
IPC: G03B35/24
Filed: 1970-03-26
Abstract: 1307397 Inspecting webs photo-electrically EASTMAN KODAK CO 26 March 1970 [1 April 1969] 14862/70 Heading G1A A photographic film is inspected for lack of colour coat by scanning it with light to which the coating is sensitive and diluting the modulation of the transmitted light. The scanning rate is made high enough not to expose the film. Light from laser 34' is passed through a shutter 38 to scanner 40 comprising a rotating mirror assembly. The light is passed through travelling film 32' to the dilution assembly 44 which includes a parthemispherical line and spherical mirror, Fig.4 (not shown), similar to that forming the subject of Specification 1307398 and a photo-multiplier 42. The presence of a short section of missed colour coat, which would produce streaks on the finished picture, causes high frequency modulation of the light having face 32c of the film. Continuous level changes will also occur due to the disappearance or thinning of the whole colour coat and since these changes indicate complete loss of useful film they are separated in filter 52 and operate alarm 54. The high frequency signals are passed through filter 44 and open gate 46 to be registered in store 48 as a count representing the position of the defect. Location counts are provided by counter 50 operated from tachogenerator 51 which is driven in synchronism with film 32'. The speed indicated by tachogenerator 51 is compared with the output of oscillator 58 and if it falls, shutter 38 operates to cut off the light from the film. In a modification, Fig. 4 (not shown), the width of the film is divided effectively into a plurality of channels by gating the output of the detector to individual recorder chains for predetermined times during each scan. A second photo-detector is used to determine the start of each scan and a pulse generator controls the duration that each recording channel is used. This system can be modified to discriminate colour coat loss streaks which produce successive modulations on successive scans from substrate slubs which do not, by use of the circuit of Fig. 5 (not shown).

Abstract: 434,288. Switching systems for resistance heating apparatus; locking switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and HUNT, M. S. H., c/o General Electric Co., Wembley. Middlesex. May 18, 1934, No. 15125. [Class 38 (iv)] [See also Group XXXVII] A four position rotary switch 1 controlling the loading of an electric heating - apparatus is interlocked with a tumbler switch 5 controlling the insertion of a resistance 2 into the heating circuits so that the switch 5 can only be switched on through a rod 9 when the switch 1 is in the position in which insertion of the resistance 2 would not result in the passage of excessive current through it. The switch 1 has an " off " position, a " low heat " position in which two heating elements are in series, a "medium heat " position in which one element is connected across the supply, and a " high heat " position in which both elements are in parallel across the supply. A disc 13 is provided on the shaft 4 of the switch 1, having two cut-away portions and a tongue as at 14. Co-operating with the disc 13 is a bracket piece 15 secured to the rod 9 and provided with a resilient spring strip 16. The arrangement is such that the disc 13 and bracket 15 prevent actuation of the switch 5 except in the " low heat " position when the spring 16 can be pushed past the tongue 14 which holds the switch 5 actuated against the action of a returning spring 11. In the actuated position the switch 2 inserts a resistance in the heating circuit. Movement of the shaft 4 to increase the heating or to switch off, brings the one or other cut-away portion of the disc opposite the spring 16 and permits the release of the switch 5 to short circuit the resistance 2.
