Title: Improvements in or relating to electrical recording devices for copying telegraphs and the like
IPC: H04N1/032
Filed: 1927-08-11
Abstract: 276,009. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Ranger. R. H.). Aug. 12, 1926, [Convention date]. Copying-tetegraphs. - In a copying-telegraph receiver, a picture is recorded by application of heat to sensitized paper such as that described in Specification 276,020 so as to discolour different parts of the surface in different degrees. The heat may be applied by means of a gas jet or electric spark-gap which is moved over the paper by means illustrated in Fig. 7. The drums 5 bearing the paper are intermittently rotated a step at a time on closure of contacts 96, 97 by either of two rotating arms 95 which are continuously driven through gearing by a motor 78. Closure of the contacts 96, 97 momentarily operates an electromagnetic clutch which causes the shaft 120 carrying the drums 5 to be rotated a short distance by the motor 78 through reducing gearing. The carriage which bears the hotair jet or spark-gap is reciprocated axially in front of the drums 5 on guides 121 by mechanism driven from the motor 78, completing one stroke for each slight rotary movement of the drums. Recording by means of heated gas jet. Heated air or other gas, such as nitrogen, carbon dioxide or a burning gas jet, may be directed from a nozzle 2, Fig. 2, against heat-sensitive paper mounted on a drum 5, except when blown aside by a cold jet from a second nozzle 3. A heating- coil 8 and asbestos lagging 29 are provided for the hot-air jet, and the cold jet is controlled by the received signals which energize an electromagnet 26 controlling a valve 19. In a modification, the cold jet is omitted and the force of the hot jet may be controlled bv a shutter operated by a telephone diaphragm through linkwork. Spark-gap apparatus.-The required heat alternatively may be applied by passing sparks at 1500 volts between electrodes 48, 49, Fig. 4, which are mounted close to the sensitized paper on the drum 5. The electrode 48 can be adjusted in relation to the other electrode 49 by turning the set-screw 56 and so rocking the arm 52, which carries the electrode 48 and is pivoted against the block 54. The electrode 49 is similarly mounted on an adjustable arm 53. The block 54, which carries the electrodes, is mounted on an arm 47 which is adjustably supported on an angular plate 65 which is rotatably adjustable about the screw 66. Screws 62, 63 and slots 60, 61 permit the arm 47 to be adjusted. Vertical and lateral adjustments are made by turning the screws 66 and 43 respectively.

[Class 97 (i)] To effect prolonged exhibition of a single image the to-and-fro movements of the claw are stopped by engagement of a latch with a dog on the claw arm, the latch being operated either by hand or automatically. As shown in Fig. 2 the claws 20, 20a, are carried on a lever 22 sliding in guides 24a, 25a pivoted to a shaft 47, the vertical oscillations of the lever being effected by a cam 23 and the horizontal oscillations by engagement of a pin 26a with a roller 50 on the lever, the roller being held in engagement with the pin by a spring 51. To lock the feed a latch 32, Fig. 6, carried on a shaft 33 engages a dog 34 on the lever. The shaft 33 also carries a double throw lever which, on rotation of the shaft, locks the film spools against rotation. The rotation of the shaft 33 may be affected manually or by engagement of an arm 44a, Fig. 9, pressed by a spring 52 against the film 55, with a knotch 55a of the film, the arm being connected to a shaft 46 carrying an extension 46b which, on rotation of the shaft, depresses the latch 32 to stop the feed. To withdraw the arm 44a from engagement with the film when threading the film an extension 46a on the shaft 54 is engaged by an arm 45 connected to a spring-actuated pawl 42, Fig. 8, normally held by a plunger 4. In opening the gate to thread the film, the plunger is removed, the pawl 42 rotates in the direction of the arrow 56 and the shaft 54 rotates to remove the arm 44a from engagement with the film. The claw arm 27, Fig. 4, is supported on the lever 22 by a screw 29 so that it may be moved to engage either the perforations on both sides of a wide film, or so that one claw engages the central perforations of a narrow film.

Abstract: 1,260,839. Regenerated cellulose strips. COURTAULDS Ltd. 11 June, 1969 [6 May, 1968], No. 21320/68. Headings B5B and B5N. A strip comprises flat filaments of regenerated cellulose, e.g. viscose rayon, having a width to thickness ratio of at least 5 : 1, adhering to each other or to a substrate sheet, e.g. of wood pulp paper or regenerated cellulose film. The flat filaments extend along the length of the strip and may be straight or meandering and parallel or crossing one another. Interfilament contact is necessary in forming strips which consist of the filaments alone, the filaments adhering to each other by hydrogen bonding or by the addition of a size, e.g. sodium carboxymethyl cellulose or a methyl cellulose or hydroxyethyl cellulose. When the strip comprises a substrate sheet adhesion thereto of the filaments is by hydrogen bonding optionally assisted by a size. The flat filaments may be made by spinning an inflated filament of regenerated cellulose which is allowed to collapse to the flat filament. Dry flat filaments may be adhered to form a strip by wetting a collection of them with a swelling agent, e.g. water or aqueous sodium hydroxide, and compressing the collection. Alternatively a freshly coagulated tow of viscose rayon filaments may be spread to form a band, freed from surface moisture, led over a series of heated arcuate surfaces under tension so that the band is compressed and dried in the compressed condition. When the strip comprises a substrate sheet, the never-dried tow may be spread on a freshly laid, never-dried wood pulp paper sheet, the assembly then being compressed and dried. The strip may have a width of ¢ cm. to 1 m., the narrower strips being used as tying twines, and the wider strips as wrapping papers and wall papers in which the flat filaments provide the decorative effect and are laid on the substrate according to a predetermined pattern or randomly.

Filed: 1973-05-08
Abstract: 1431293 Facsimile apparatus XEROX CORP 8 May 1973 [16 May 1972] 21869/73 Heading H4F A facsimile transceiving apparatus comprises a document scanning station and a document reproduction station, a source of light for providing a light beam for alternatively scanning a document at the document scanning station or for forming an image at the document reproduction station, optical means defining a path for said light beam between the source and one of said stations and means for selectively interrupting the path of said beam to said one station and for causing the transmission of said light beam to the other station. Laser 50 provides a light beam 54 which is directed by mirrors 58 and 62 to a galvanometer 52 having a reflective surface 64 (Fig. 5). In a printing mode. the surface 64 directs the light on to a mirror 66 which passes the light on to a drum 70. The drum has a photosensitive surface which is scanned by the modulated light beam. Scanning is performed by movement of the galvanometer. During formation of the latent image on the drum one element of a number of attenuating elements on a rotatable assembly 56 is placed in the path of the light beam. Various attenuating elements are provided corresponding to different scan rates so that an equal exposure is given to the drum surface for any scan rate. An anamorphic lens assembly 60 alters the circular cross-section of the light beam to give an elliptical cross-section, narrowest in the scanning direction. After scanning is complete, the image on the drum is developed by application of toner particles mixed with ferromagnetic carrier particles and paper is then applied to the drum to transfer the image. In a document scanning mode, a motor 174 via gear-box 176, rotates a cam 178 having a sloping surface 180. Rotation of the cam forces a mirror 74 up into the path of the light from the galvanometer and in this position the mirror 74 directs the light to a mirror 76. The light beam is now scanned across a transparent body 82 placed along a slit in a platen plate 78. The body 82 may comprise e.g. glass. A document 80 is passed behind the body so that it is scanned by the light beam light diffusely reflected from the surface of the document being received at a photodetector 84.
