The dry electric shaver (10) includes a pair of movable cutter blocks (31) reciprocatively movable by a drive bar (15) with respect to a fixed perforated comb (25). The cutter blocks (31) are coupled to the drive bar (15) by a unitary one-piece plastic cutter support (40) having a central body (41) engageable with the drive bar (15) and having coaxial torsion bars (48,49) extending from the opposi...

In order to assure a safe activation and deactivation of resonant circuits on tags used for being placed on or in articles by means of small electromagnetic or electric fields easy to handle, regions are created in the conductive elements forming part of the resonant circuit, especially in the capacitor parts where the insulating material between two conductive elements in a precise manner is made...

26 DISPOSITIF D'ECLAIRAGE ET APPLICATION A UN DISPOSITIF DE VISUALISATION L'invention concerne un dispositif d'éclairage dans lequel un dispositif holographique (HPi) sépare les polarisations d'un faisceau incident. Le faisceau polarisé résultant est transmis à un dispositif holographique (HLi) focalisant le faisceau en différents points d'un écran. Cet écran peut être un écran à cristal liquide (...

2096833 9209589 PCTABS00130 Procédé de préparation de dérivés du taxane de formule générale (I), nouveaux dérivés ainsi obtenus et compositions qui les contiennent. Dans la formule générale (I), R représente t.butoxy ou phényle, R1 représente hydrogène ou acétyle et Ar représente phényle substitué ou .alpha.- ou .beta.-naphtyle éventuellement substitué. Les nouveaux dérivés du taxane sont utiles c...

A mineral fibre composition which is soluble in biological fluids contains substantially 45-65 % by weight of SiO2, 15-40 % by weight of CaO, 0-20 % by weight of MgO, 0-6 % by weight of Na2O + K2O, and in addition aluminium and/or iron oxides as well as phosphorus oxide in such amounts that the weight ratio of P2O5 to the sum of Al2O3 and iron oxide is circa 0.4 to 6.

Gellable compositions containing: (a) water; (b) a water-soluble organic polymer bearing special chelating functional groups; (c) a multi-valent metal ion capable of causing the polymer to crosslink, are useful to recover oil from a oil field. Said compositions make it possible gels to be obtained which are endowed pith improved physical properties and show a higher stability under the condition...

This invention concerns a device for keeping dental arches in an open and stable position during sleep. The device in question consists of a middle vertical bridge joining two overlying horizontal anatomically curved wings which couple the same to the upper and lower jaw arch.
