Title: Thermal reproduction
IPC: G03B27/30
Filed: 1963-03-11
Abstract: 972,587. Printing surfaces. A. G. GULKO. March 11, 1963, No. 9610/63. Heading B6C. [Also in Division G2] A printing plate suitable for reproducing copy is formed by heating a layer 13 of a transparent heat-insulating material such as glass to an elevated temperature in a pattern 18 corresponding to the pattern to be reproduced, and dusting the differentially heated surface in a chamber 19 with finely divided particles of printing material which become tacky on heating. The particles adhere to the heated areas and a sheet of absorbent paper, Fig. 4 (not shown) is then pressed on to the surface and the printing material is forced into the sheet. Heat may enhance the absorption. The printing dust may be a mixture of vinyl chloride, vinyl acetate and carbon black and may contain an antistatic. The layer 13 may be dusted again and used to print further copies. Fig. 1 depicts the layer 13 being differentially heated by radiant heat from an infra-red lamp 15, which heat is absorbed by indicia 12 on an original 11. Copies may be continuously supplied by a rotary apparatus, the cylinder being of glass. U.S.A. Specification 2,626,877 is referred to.

Title: Improvements in or relating to the production of plywood
IPC: C09J161/06
Filed: 1937-04-05
Abstract: A phenol-aldehyde resin in the "resitol" stage, in which it softens but is infusible under heat, is employed for joining plywood laminae. It may be produced, for example, from phenols and formaldehyde, or phenols, wood oil, and formaldehyde.  In an example, 50 kilograms of a novolak resin produced from phenol, formaldehyde, and hydrochloric acid are melted with 10 kilograms of hexamethylenetetramine, with or without 20 to 30 kilograms of water, and the product is heated so that it is more or less completely brought to the resitol stage.  It is then finely ground and made into a dispersion with 100 kilograms of water, which may be applied with a spraying gun to the surfaces, adhesion being brought about in a hot-press at 150 to 170 DEG  C. for 1 to 3 minutes. The dispersion may be made in other non-solvent liquids, and may be applied with a brush, or the dry powder may be dusted on. Additions may be made to the resin, such as 5 per cent of wood flour, dyes for colouring purposes, and powdered asbestos for increasing resistance to fire.

Title: Improvements relating to apparatus for storing television pictures
Inventor: VOLES ROGER
IPC: C10G35/06
Filed: 1963-03-12
Abstract: 1,076,165. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 12, 1964 [March 12, 1963], No. 9661/63. Heading H4F. The invention relates to apparatus for storage images under low lighting condition of objects which are in motion with respect to the apparatus e.g. obtaining images of a scene from an aircraft. The apparatus comprises a television camera, Fig. 4, and a storage tube for storing the television picture information from the camera the scanning signals which are applied to the camera being applied to the storage tube after passing through scan transformation circuits, Fig. 5 (not shown), which allow for the movement of the scene relative to the aircraft during the integration time of the camera. The movement of the image applied to the storage tube is compensated with consequent increase in resolution for a given integration time or in integration time allowable for a given resolution, the storage tube storing as many pictures from the camera superimposed on one another as frames of the scan occur in the integration time. The Specification includes a mathematical analysis of the movement of the scene being photographed and the resulting equations which neutralize this movement are implemented by means of the scan transformation circuits, Fig. 5 (not shown), which modify the horizontal and vertical scanning signals applied to the storage tube. Although the scan transformation increases the period of integration, an upper limit to this period is set by the time objects take to cross the field of view. Instead of correcting the storage tube scan an inverse correction may be applied to the camera scan, or parts of the correction may be applied to both. Preferably the storage means includes a luminescent screen displaying the stored data and the operator has a light pencil to select where he wants maximum resolution of the image. The light pencil includes a phototransistor and is held at the point of interest of the luminescent screen so that it gates the co-ordinates at the time when the electron beam strikes the point of-interest of the screen.

Title: Communications network
Inventor: HILL ALAN MICHAEL
IPC: H04Q11/00
Filed: 1996-07-25
Abstract: A communications network in which a central switching node (70) has at least two sets of both input ports (52) and output port (56) coupled to respective sets of transmitters (Tij) and receivers (Rij) by passive optical networks (54) and (58) and demultiplexers (52) and multiplexers (59). The transmitters (Tij) are tunable so that each can be selectively coupled to one of the input ports (52). The receivers (Rij) are also tunable so the output ports (56) can be selectively coupled to the one or more of the receivers (Rij). Alternatively, the demultiplexers (55) and multiplexers (59) can be tunable. This devolves some of the switching function outside the central switching node (50) thereby reducing the component count.
