Abstract: 1368880 Radio signalling COMMUNICATIONS SATELLITE CORP 8 June 1972 [10 June 1971] 26908/72 Heading H4L A radio repeater station, e.g. on an artificial earth satellite, of the type having multiple aerials to provide "spot beams" enabling transmission between a number of earth stations to take place on overlapping frequency bands, is provided with means for translating the received signals into non-overlapping frequency bands for the purpose of connecting any received band to any desired band of any transmit beam and means for translating the rearranged signals into overlapping frequency bands for transmission. As shown in Fig. 1, the repeater receives three spot beams. A, B, C which are applied to N part filters 10, 12, 14 respectively. Each filter divides the beam bandwidth into frequency bands (slots) which may be individually routed. The band slots are supplied to mixers 16a to 16e respectively each supplied with a different frequency from local oscillators 18a to 18e. The frequency translated slots are combined at 20 and the resulting signal is band filtered at 24 to provide three bandwidth segments. These segments are supplied to mixers 26a to 26c respectively, co-operating with local oscillators 28a to 28c where they are converted to overlapping frequency bands for transmission as spot beams AA, BB, CC. Routing is controlled by the local oscillator frequencies applied to the mixers 16 which are derived from a frequency synthesizer using a step recovery diode comb generator, and a plurality of YIG filters. The tuning voltages for the YIG filters may be controlled by a digital processor which is either programmed or responds to signals from the ground.

Title: Improvements in or relating to the polishing of glass ribbons and like materials
IPC: B24B7/26
Filed: 1960-08-04
Abstract: 950,611. Grinding and polishing glass ribbons. GLACERIES DE LA SAMBRE S.A. Aug. 4, 1960 [Aug. 8, 1959 ; July 20, 1960], No. 27140/60. Heading B3D. During the forward movement of a glass ribbon through grinding and polishing stages the temperature of the margin zones of a portion of the ribbon situated at any given instance between successive series of tools is subjected to adjustment. In the arrangement shown in Fig. 5, each of the areas positioned between successive polishers 19, 20, 21 is subjected to temperature variation by supplying hot water through sprinklers 25a, 25b to the upper and lower faces of the marginal zones and through sprinklers 26a, 26b to the upper and lower faces of the central zone. The sprinklers are disposed between pairs of conveyer rolls 16a, 16b and the hot water they supply is arranged to produce a uniform temperature throughout the width and thickness of the area despite variations of the temperature at different points when the ribbon enters the area and so provides for correct tracking. In the embodiment shown in Fig. 6, supplies of hot and cold fluid from respective pipes 105, 106 pass through two-way valves 103, 104 and three-way valves 101, 102 to sprinklers 25Aab, 25Bab for distribution over the upper and lower faces of the marginal zones. By suitable operation of the valves the temperature of the supplies to the margins can be adjusted so as to provide for correct tracking of the ribbon. By also controlling the temperature of the supply of fluid to the upper and lower faces of the central zone through sprinklers 26a 26b, it is possible to ensure that the temperature of the ribbon is uniform throughout the affected area. The marginal and central sprinklers may be mounted on holders arranged for vertical, longitudinal and transverse adjustment. In the further embodiment shown in Fig. 7 for varying the marginal temperatures, the marginal zones are supplied with compressed air through nozzle blocks 207, 208 which are separately controlled by valves 213 and the temperature of the air supplied through the nozzles is adjustable by electric heaters 203, 204 and 205, 206; the central zone may also be provided with temperature controlling means.  The temperature adjustment may alternatively be effected by other appropriate means, e.g. by banks of sprinklers supplying water acidulated with sulphuric acid, hot gas or steam, or banks of liquid or gas jets combined with electric heaters, or electric resistors or electromagnetic oscillators. Regulation may be effected by non-automatic, semi-automatic or fully-automatic means. Specification 755,832 is referred to.

Title: Method of making decorative thermoplastic materials
Inventor: LANE FREDERICK HENRY
IPC: B05D5/06
Filed: 1964-07-07
Abstract: A decorative thermoplastic material is made by supporting a body of thermoplastic material having a surface to be decorated disposed uppermost and in a substantially horizontal position, spreading over the horizontal surface a layer of particles of a thermoplastic resin composition, applying thereto under pressure a heated patterned tool, cooling and removing unattached particles say by brushing, blowing or suction.  The body of thermoplastic material may be flexible or rigid sheet material e.g. rubber, and synthetic resin, such as polyvinyl chloride, compositions. Suitable particles mentioned are cellulose acetate powder, powdered polyethylene and polyvinyl compositions, having incorporated therein colouring agents and/or plasticizers and/or stabilizers and/or fillers.  The particles may have a colour different from the basic thermoplastic material.  The body of thermoplastic material may comprise the flock of a flock-coated material.  The flock materials may be fibres of nylon and of polyethylene terephthalate, mixtures thereof with non-thermoplastic fibres.  Fibres such as rayon and cotton are included in the term thermoplastic material since they are deformable.  The material carrying the flock may be flexible or rigid e.g. sheets of rubber compositions and textile materials. The powder-covered thermoplastic material with the tool resting thereon may be placed between the electrodes of a high frequency electric welding machine, and a pressure applied by reducing the separation between the electrodes. The tool and resin are heated by establishing a high frequency alternating electrostatic field between the electrodes to fuse the powder.  The electrodes may then be cooled, separated and the tool removed.  The tool may be heated and then applied to the powder covered thermoplastic material.  In example 1 powdered cellulose acetate composition is embedded in nylon flock attached to a cured sheet of a rubber composition electrostatically using a polychloroprene latex adhesive.
