Abstract: 1,076,604. Photo-electric flaw detection. VSESOJUSNY NAUCHNO-ISSLEDOVATELSKY INSTITUTE GOZNAKA. June 30, 1964, No. 18082/64. Heading G1A. Sheets of paper 2 are inspected by beams of light which are scanned across each side of the paper by mirror drums 16, 16a co-operating with photo-multipliers 22, 22a receiving light reflected from the sheets. Cylindrical lenses 19, 19a and 20, 20a are provided to focus the scanning and reflected beams respectively. A further photomultiplier 25 detects flaws that show up as a variation in the intensity of transmitted light. The width of scan is limited to the width of the sheets 2 by mirror masks 18, 18a which, when the scanning beam is outside these limits, reflects the beam to photo-multipliers 23, 23a to produce compensating signals for addition to the output of photo-multipliers 22, 22a to produce a steady D. C. level. The outputs of the photo-multipliers 22, 22a and 25 are analysed with regard to the amplitude of short duration variation signals and the dimensions of signals representing flaws along and across the sheet. The permissable amount of different types of flaw may be different. When a flaw is detected, a pulse is fed to a delay circuit which energizes reject means when the defective sheet has reached a reject station. The sensitization of the apparatus to detect flaws and the passage of a reject pulse through the delay circuit is controlled by sources of infrared radiation 29, 30 co-operating with photo-diodes 27, 28 to detect the passing sheets. The photo-multipliers are insensitive to infrared.

Title: Improvements in or relating to television or like systems
Filed: 1935-06-27
Abstract: 458,791. Television. BAIRD TELEVISION, Ltd., LANCE, T. M. C., and PATTINSON, E. H. FODEN-, 58, Victoria Street, Westminster. June 27, 1935, No. 18429. [Class 40 (iii)] A television &c. system particularly adapted for reproduction in colour or of stereoscopic effects employs at the transmitter or receiver a lenticular grating composed of a series of adjacent cylindrical lenses with their axes parallel, whereby at the transmitter a single object produces, as regards colour or duality of images, a composite signal, or, at the receiver, such a composite signal is synthetized into a single image. In the transmitter shown, the grating 7 is arranged with its plane surface in proximity to a moving film 3 and is designed to project upon the film a striated image of a light filter 10, which has zones 4, 5, 6 of the three primary colours. In conjunction with a lens 2 these elements produce upon the film 3 an image of an object 1, in which each third strip corresponds with a particular primary colour. The film is developed and fixed with the image in monochrome, and is then scanned at the transmitter, e.g. by a cathode-ray, in lines at right-angles to the direction of the strips. A replica of the film is thus reproduced at the receiving station and may be projected upon a viewing screen by an optical system which is the reverse of that employed at the transmitter. The film may be automatically maintained in registration with the lenticular grating by arranging that the strip extending along one edge of the film should co-operate with a slit attached to the grating and with a photo-cell sensitive to a particular colour so as to control electromagnetic adjusting means for the grating. When stereoscopic effects are to be obtained, the grating 7 is used in conjunction with a pair of separated lenses, Fig. 2 (not shown), so that every alternate strip upon the film 3 corresponds with the right or left eye image of an object.

Abstract: 357,185. Automatic exchange systems. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, and BEALE, C. E., 59, Towers Road, Wavertree, both in Liverpool. June 18,1930, No. 18651. [Class 40 (iv).] In a system in which a group of Strowger-type switches are controlled by common apparatus multipled thereto, the usual individual associating relays are dispensed with and the common line relay is connected to the speaking wires of all the idle switches. As far as possible, each control apparatus is arranged to serve only one of the switches forming each supervisory group. Upon seizure of the switch, earth on the test wire 12 is extended through the relays H to mark all the switches of the group busy, while relay H of the seized switch operates its light armature h1. Line, release and dialling relays A, B, C energize in the common apparatus and impulses are repeated to the vertical magnet VM. At the first step, relay BX energizes over contact ONS4, locks and disconnects battery from the test wires of all the switches of the group. Relay C falls back at the end of the train and connects up the rotary magnet RM, which interacts with relays G, ST to find an idle trunk. At the first rotary step, the test wire 12 is opened at contact OR1. When an idle trunk is reached, relay G is short-circuited by battery on the test wiper P and relay K energizes and holds relay ST operated, so that switching relay H energizes and locks. The relapse of line relay A initiates release of the common apparatus. If all the trunks are busy, relay BB energizes over cam springs S in series with relay K, relay G being effectively short-circuited. Relay H energizes, but line relay A is maintained over the eleventh terminals, and busy flash and tone are connected thereto, release relay B being held in the usual manner during the flash period. The release magnet Z is connected to the test wire 12 at the first vertical step and energizes in two steps when the short-circuiting earth is removed therefrom when release takes place. The Provisional Specification describes slightly modified circuits.
