  • Ink transfer arrangement and method in a printing press
    Patent number: 4669379
    Abstract: An ink transfer arrangement for and a method of transferring ink to an engraved die surface of a reciprocatable die in a printing press of the type including a die drive for reciprocating the die, and a press ram drive for pressing sheet material to be printed against the ink engraved die surface to produce intaglio printing are disclosed. A rotatable inking roller is normally mounted on an ink fountain in inking engagement with a fountain roller also mounted on the fountain. Ink from the fountain is transferred to the fountain roller, and thereupon to the inking roller. The inking roller is mounted for limited displacement relative to the fountain roller in a direction transverse to the axis of rotation of the inking roller.

  • Multi-dimensional-access memory system with combined data rotation and multiplexing
    Patent number: 4667308
    Abstract: A data memory arrangement includes n columns of storage elements each column being addressable only one element at a time and having at least n.sup.2 storage elements so as to provide a succession of square arrays. Each square array comprises square sub-sections. On storage of a complementary array of data the data is multiplexed from each square array to the next within each sub-section and after each cycle of such multiplexing the sub-sections are rotated one step cyclically. Such rearrangement of data gives freedom and speed of simultaneous access to data words occurring in original rows and/or columns without excessive penalty in the complexity of the addressing system.

  • Energy dissipator
    Patent number: 4664853
    Abstract: An energy dissipator for downwardly discharged water utilizes a hollow cone valve located in a chamber open to the atmosphere and arranged to direct water emerging therefrom at an angle inclined downwards from the horizontal towards a region of a surrounding wall, and a pair of troughs around the inner surface of the wall above and below the region with the open mouths of the troughs facing each other. The troughs serve to reduce considerably the incoming energy of the water in a relatively small volume, the effect being enhanced by splitting the water emerging from the cone valve into a series of discrete jets, between which air can flow.

  • Night vision systems
    Patent number: 4660943
    Abstract: A night vision system comprising a helmet (1) having a transparent visor (13 or 15) before or movable to a position before the eye positions (IL, IR) of an observer wearing the helmet and a night vision device (19) having two eye pieces (22L, 22R), one for each eye, supported dependant from the helmet (11) so as to present the eye pieces (22L, 22R) of the device (19) at a short distance before the helmet wearer's eye positions and the visor (13 or 15). The device (19) is supported by means of a four-bar linkage arrangement (A,B,C,D) which constrains the eye pieces (22L, 22R) for rotational movement about the respective eye positions (IL, IR) between different operative positions, and so that the eye pieces (22L, 22R) do not make contact with the visor (13 or 15) during eye piece movement.

  • Power-generation plant and method
    Patent number: 4660375
    Abstract: Power generating plant comprising a pressurized fluidized bed combustor (PFBC) (11) in combination with a gas turbine (12,13) and associated compressor (14), is enabled to operate over an extended range of load and to respond rapidly to substantial load changes by arranging for such range and changes to be achievable while maintaining the PFBC at substantially constant temperature and varying, instead, the gas pressure in and mass flow rate through the PFBC. For effecting the required changes, the gas turbine and/or the compressor are provided with variable geometry, in the form of variable inlet or inter-stage guide vanes (34) and/or interstage bypass or blow-down valves (39,40).

  • Magnetic field sensors
    Patent number: 4656421
    Abstract: A magnetic field sensor in the form of an arcuate element comprising two superimposed strips of material is described. The magnetostrictive constant along the longitudinal axis of one of the strips is greater than that of the other strip, the latter strip carrying at each end a post. In use of the sensor a single mode optical fibre is attached to the element via the posts such that the part of the fibre between the posts extends along a chord of the arc defined by the element. A variation in applied magnetic field in the plane containing the arc gives rise to a variation in the part of the fibre between the posts. Light passing through the fibre is thus phase shifted by an amount dependent on the value of the applied magnetic field.

  • Decorative bow-forming ribbon assembly
    Patent number: 4656064
    Abstract: A bow-forming ribbon assembly has a decorative flexible ribbon and a drawstring connected loosely to, and freely guided through pairs of apertures formed in, the ribbon lengthwise thereof. Between each pair of apertures, a bending zone is provided which extends at an angle of inclination, which angle is different and of opposite slope from that of the adjacent preceding inclination angle. During forming of the bow, the drawstring bends the ribbon across each bending zone, and forms bow loops distributed at various angles around the axis of the bow to form a pompon-like shape.

  • Optical multi-fibre switch
    Patent number: 4652081
    Abstract: A switch for switching a single fibre to any one of a plurality of fibres by aligning their end faces is composed of a funnel-shaped guide. The single fibre is mounted in the narrow end portion of the guide and the plurality of fibres are held in the wide end of the guide. Each of the plurality of fibres is independently movable longitudinally into the guide, for example using electromagnetic actuators, so that as a desired fibre moves further into the guide, its end is guided towards the narrow end where it will align with the end of the single fibre.

  • Shaft encoder having a concave reflective element with two regions of different reflectivity for light within two different wavelength bands
    Patent number: 4652747
    Abstract: An optical method of measuring displacement and a sensor for use in the method comprising a light guide and a concave reflective element positioned such that one end of the light guide is at the center of curvature of the reflective element. The reflective element has different regions having different reflection coefficients for light within two different wavelength bands. A member is interposed between the end and the reflective element, the member having light transmissive properties which vary spatially over the member in a direction transverse to the optical axis of the element. The member and reflective element are supported so as to allow them to be displaced relative to one another in a direction transverse to the optical axis of the element.

  • Display arrangements for head-up display systems
    Patent number: 4652870
    Abstract: A display arrangement for a head-up display system e.g. for an aircraft, wherein the combiner (13) comprises a first tuned reflective optical film (39) through which an observer (14) views a distant scene and second and third tuned reflective optical films (41 and 43) positioned outside the observer's view of the distant scene through the first film. Light from a projector (11) passes first through the nearer (43) of the second and third films, is then reflected at the other (41) of the second and third films, is then reflected at the nearer film (43) and then passes through the other film (41) to the first film (39) where it is reflected towards the observer. The three films are normally designed to provide the combiner with a desired optical power, the one (43) of the second and third films nearer the projector suitably being concave toward the other (41) of the second and third films for this purpose.
