Title: Automatic butt welding appts. for optical waveguide fibres - where motor driven micrometer head and limit stops control movement of one fibre towards the other
Inventor: TODA YUICHI
IPC: G02B6/255
Filed: 1980-04-21
Abstract: Two fibres to be joined together coaxially are each held in a clamp, so their bared ends rest on anvils but are sepd. from each other by a retractable spacer. One clamp is stationary, but the other moves one fibre axially when the spacer is removed. The position of the mobile clamp is controlled by three limit stops employed in conjunction with a micrometer head driven by a motor; and the fibre ends are heated, e.g. by an electric arc, to make the weld. The mobile clamp is pref. first held against one limit stop by a lock, which is released so a spring can press the clamp against the micrometer head. Accurate butt welded joints are obtd. with a min. amt. of scrap.

Title: Thermal release device for up-and-over garage door - has independent electric door operating mechanism which operates when rapid temp. rise occurs
IPC: A62C2/24
Filed: 1980-04-28
Abstract: The door is held in the open position against a closure bias by a device that is released automatically in dependence on a rapid temp. increase. The door is also coupled to an electric operating motor for moving it between open and closed positions without affecting the operation of the thermal release device for automatic closure. Pref., the door comprises a metal panel with rollers at the top and bottom corners respectively guided along spaced horizontal and vertical rails. A cable is coupled at one end to each bottom corner of the door panel and at the other end to a counter-weight, with a coupling rod extending between the upper edge of the door panel and an endless drive chain. The cable and chain are both driven via a differential mechanism coupled to the electric motor via a clutch associated with the thermal release device.

Title: Remote alarm system using telephone link - includes electromechanical connection facilitating automatic dialling using standard telephone set
IPC: H04M11/04
Filed: 1980-07-29
Abstract: The alarm transmitting a signal to a remote position by telephone consists of an attachment which is fitted to a telephone set. It has a metal or wooden frame housing all its circuitry, into which the telephone may easily be fitted. The set is held in the appropriate place by wedges, fitting taking only a few seconds.

IPC: C08F4/36
Filed: 1980-10-02
Abstract: L'invention a pour objet un procédé de préparation d'une dispersion liquide aqueuse de polymères, consistant à copolymériser des peroxydes polymères avec des monomères de type vinylique, réalisant ainsi la synthèse d'un copolymère contenant des liaisons peroxy, le copolymère résultant étant soumis à une copolymérisation séquencée avec des monomères de type vinylique différent, ce qui a pour effet de cliver les liaisons peroxy et de produire des copolymères séquencés avec un rendement élevé. Les copolymères séquencés contiennent des parties polymères solubles dans l'eau ou un mélange d'eau et de solvant organique dit solvant C, et des parties polymères insolubles dans le solvant C. Lorsque le copolymère séquencé est mélangé avec du solvant C, la partie polymère insoluble du copolymère séquencé coagule dans le solvant C en formant des particules et la partie polymère soluble du copolymère séquencé s'allonge dans le solvant C avec pour résultat que le mélange résultant se présente sous la forme d'une dispersion.

Title: Twin roll mills of plastic for grinding cereals - for more quiet, gentle and safe running than use of metal rolls
IPC: B02C4/30
Filed: 1980-12-02
Abstract: A twin roll mill for grinding cereals has rolls made of plastics materials. Compared with use of metal rolls, the plastics rolls are quieter, lighter and offer a softer initial impact on the grain. The lower inertia of the plastics rolls is safer and less readily establishes resonant vibration at high roll speeds. The roll surfaces may be smooth or textured, opt. are of glass fibre reinforced resin or of a hydrocarbon polymer. In an example, walls were fixed to metal shafts via pairs of end plates keyed to the shaft and anchored concentrically into recesses at the ends of the cylindrical plastic roll bodies by wood screws or equivalent fastenings.

Title: Compact topological interconnection device - localises nodes and crossovers of complex circuit formed on single layer support with connections formed by metal strips
Inventor: VAL CHRISTIAN
IPC: H01L23/498
Filed: 1980-12-12
Abstract: The device consists of a substrate with external contacts which regroup the cross over points and connecting nodes of a complex electronic circuit produced on a single layered support. The circuit elements are connected to the external contcontacts of the device by non convergent metal strips. The cross overs of the circuit are enclosed in a small multilayer volume. If the number of connections is too large, several of the devices could be used together. The cross overs are made on the semiconductor, or in the form of metal conductors in several separate layers with insulating layers of silicon nitride between. They may be made using serigraphy or diffusion in silicon or by point to point interconnections using gold or aluminium wire. The wires may be glued to a substrate using automatic band transfer of metal films or by encapsulation in insulating resin. The device may be encapsulated in a dual in line package.

Title: Pneumatic jacks or tyre supports - of filament reinforced and constrained fabric to control the shape of use in service
Inventor: FELSER JEAN HENRI MARCEL
IPC: B29D22/02
Filed: 1981-02-06
Abstract: Inflatable cushions for use in supporting punctured large-scale tyres, as vehicle jacks, etc. are controlled in their profile when pressurised by selective application of overwound inextensible fibres or reinforced fabrics. Used to control the inflated cushion profile to an optimum shape for e.g. supporting the body of a tyre for a tractor, earth-mover, etc. The windings may be laid up on an extensible casing temporarily supported internally by a core of matl. which may subsequently be removed by e.g. fusion or dissolution, e.g. expanded polystyrene. May be used to make a cylindrical pattern cushion adopt a partially flattened profile to mask that of an industrial tyre section.
Patent FR-2475833-A1 (FR)
Inventor: DISCHERT ROBERT ADAMS
IPC: H04N7/46
Filed: 1981-02-06
Abstract: In a method for transmitting signals, particularly for a digital television system, the data frequency is lowered by only transmitting or recording bytes which represent half the scanned pixels. In addition, guide and control bits are transmitted which specify which of the transmitted bytes best correspond to the bytes not transmitted so that the pixels represented by the latter can be reconstructed again later.
