Patent GB-2233963-A (GB)
Title: Document feeder
Inventor: GRAHAM JOHN FLETCHER
IPC: B65H3/52
Filed: 1989-06-02
Abstract: A document feed system comprises a feed wheel (10) mounted on a first rotatable shaft (13), and a retard wheel (11) mounted on a second rotatable shaft (14). The first shaft is driven by a motor and the second shaft is mounted in a bearing fixed in a pivoting arm. A first pulley (17) is fixed on the first shaft and a second pulley (19) is coupled to the second shaft through a slipping clutch (18). A belt (20) passes round the first and second pulleys and also round an idler pulley (21) which is rotatable on a spring loaded shaft (22). The arrangement is such that the belt (20) pulls the first and second shafts towards each other so that a document may be gripped between the feed and retard wheels. If a single document is located in the flip between the feed and retard wheels it will be driven in the direction of the arrow (24). However, if two documents are located side by side in the nip, one document will be driven in the direction of the arrow (24) while the other is retarded relative to that document. <IMAGE>

Title: A transfer method and apparatus therefor
Inventor: BILLINGTON ALAN JAMES
IPC: B65G27/04
Filed: 1989-08-16
Abstract: In a method and apparatus for transferring relatively light objects, the objects are supported on a cushion element 10 having a multiplicity of extremely fine and relatively short flexible fibres packed at an ultra high density pile in a backing. The fibres are aligned at an angle or inclination with respect to the base so that when the cushion element 10 or the object is vibrated the objects are transferred in the direction of lay of the fibres. The cushion element may be supported by a base with the object resting on the fibres, or the cushion element may be secured to the underside of the object 120 so that the fibres rest on the base 128. The pile may have (68-80) x 10<6> fibres per square metre, with a fibre length/thickness ratio of about 50:1. The fibres may be 43-45 microns thick and up to 2.5 mm in length. The support may be in the form of a V-section track and used in conjunction with an inspection device, or have an orienting function.   <IMAGE>

Filed: 1991-07-04
Abstract: A fuel tank-for liquid fuel for an internal combustion engine subject to orientation changes in normal use, having a flexible membrane 27 which allows changes in volume, within a rigid casing 11. The latter has a sealable fuel filler inlet (15) and a breather valve or opening 26 allowing the ingress and/or egress of air to the rigid casing 11 outside the volume enclosed by the membrane 27.

Title: Rapid-response calorimetric gauge using fibre optic interferometer
Inventor: BARTON JAMES STEPHEN
IPC: G01N21/45
Filed: 1991-07-08
Abstract: A high speed sensor for measuring heat flux directly uses an optical fibre Fabry-Perot interferometer 40 which is mounted with one of its end faces 42 flush with the surface of a specimen eg. a turbine blade, whose heat transfer characteristics are to be investigated. The sensor 40 is illuminated by a laser source 10 via a directional coupler 20 and an addressing fibre 30 of identical optical characteristics to the sensor 40. The addressing fibre 30 and the sensor 40 have low reflectivity coatings on their end faces such that some of the incident light is reflected to an interference detector 50. Here the optical phase change in the sensor reflection is detected when the sensor 40 is exposed to heat flux thereby changing its refractive index. A signal processor (not shown) relates the optical phase change to the mass density, specific heat capacity and thermal sensitivity of the sensor 40 to give a direct reading of the heat flux. A Faraday isolator 15 reduces reflections, and a second detector 60 monitors and regulates laser power output. <IMAGE>

Title: System to prevent a scrambler from generating undesired symbols
Inventor: FEBVRE PAUL ROGER
IPC: H04L9/36
Filed: 1992-10-09
Abstract: A system is disclosed for controlling the output level of an audio signal, in which a voltage controlled amplifier (18) is provided in addition to a high fidelity motorised fader (17). During normal (first mode) operation, the level of the audio signal is controlled directly by said fader, which may be adjusted in response to data from a storage device (23). On selecting a second mode of operation, the level of the audio signal is controlled by means of the voltage controlled amplifier, arranged to receive said stored data. In addition, said amplifier also receives trimming signals from said manually adjustable fader and movements of said fader in this mode are also stored, so that said modified data may be combined with the original data, to produce new data for use in said first mode of operation. The invention provides "trim mode" while providing a high fidelity resistive fader for normal operation. <IMAGE>

Title: Compositions containing sunscreens
Inventor: DAHMS GERD HERBERT
IPC: A61K8/29
Filed: 1994-05-17
Abstract: A process for preparing a sunscreen composition suitable for topical application to human skin comprises mixing particles of metallic oxide dispersed in oil and having a primary particle size less than 0.2 micrometre with one or more emulsifiers, an aqueous phase and a hydrophilic organic sunscreen so as to prepare an emulsion. The composition contains up to 10 per cent by weight metallic oxide and up to 7 per cent by weight hydrophilic organic sunscreen. The emulsions are useful as sunscreen compositions, skin protectants, moisturisers, and after-sun lotions. The measured Sun Protection Factor for a composition of the invention is considerably higher than would be expected from a knowledge of the individual UV absorbing characteristics of the metallic oxide and the hydrophilic organic sunscreen.
