Abstract: A process of preparing a catalyst component for the polymerization of a-olefins. An organomagnesium compound is deposited on an inert inorganic support, such as silica, and the product obtained is heated at a temperature of 300-1000°C in a non-reducing atmosphere. The support is then combined with one or more compounds of titanium and/or vanadium. The process of polymerizing alpha-olefins with these catalysts and a co-catalyst is also disclosed.

Abstract: O In a known optical cable, optical fibers (24) are loosely laid in a number of grooves (16) formed within an elongate plastics extrusions (14). Typically the grooves (16) follow a helical path with periodically reversing pitch, the helices centered on a central longitudinal axis of the cable. A primary reason for the helical lay is to prevent the fibers (24) from becoming stressed should a bend occur in the cable. A further benefit of loose laying of fibers (24) in a helical groove (16) of periodically reversing pitch is that any elongation of the cable core is not immediately transmitted to the fiber (24) supported by it. The fiber (24) will move from its initial loose laid position both in a direction towards the inside curve (20) of the helix and in a direction towards the base (22) of the grooves (16). When it bears against the cable core over an appreciable length, the fiber (24) will then be subjected to tensile stress. By the invention, tolerance to core elongation is increased by arranging that the grooves (16) at any point along the core cant towards the outside curve (25) of the helix.

Abstract: A vehicle transmission has an input shaft 1 from which are derived two outputs, one from gear 2 being fed via a continuously-variable-ratio transmission 4 of the rolling traction toroidal race kind and the other via gear 3, to a simple epicyclic gear 5 where they are combined. Output is taken either from the annulus 18 of the epicyclic gear (for low forward ratios, geared neutral, and reverse) or from the sun-gear 15 (for low to high forward ratios). The arrangement uses an uncomplicated gearing arrangement (a simple epicyclic gear) to combine the two outputs because the steo-down aear 3 can be chosen so as to combine the outputs at an appropriate ratio.

Abstract: Un amplificateur operationnel (18) est capable d'effectuer selectivement une variete de fonctions de circuits. Un amplificateur operationnel simple (18) utilise des condensateurs commutes (24, 32 et 36) pour echantillonner-bloquer un signal d'entree VIN pour etablir un pole de basse frequence, pour appliquer l'echantillon sur une capacitance de sortie (47 et 48) et charger la capacitance, et pour comparer le signal d'entree VIN a une reference VAG. Le circuit a multi-fonctions (12) permet une grande conservation dans la zone circuit ainsi qu'une versatilite des applications de circuit. Un mode de realisation de l'invention consiste a utiliser un convertisseur numerique/analogique de compression-extension (14) ayant un condensateur qui peut etre utilise comme capacitance de sortie (47 et 48) du circuit de l'amplificateur operationnel (12). Le convertisseur numerique/analogique utilise un convertisseur numerique/analogique a echelle R (52) couple directement a un convertisseur numerique/analogique C (50) et possede une structure de commutation qui est plus simple que les circuits comparables de l'art anterieur. Le convertisseur numerique/analogique (14) est asynchrone et possede une capacite programmable de conversion MIC suivant les lois A- et Mu-225. Un circuit filtre de reception de l'amplificateur operationnel (16) est couple directement au convertisseur numerique/analogique C (50), lequel circuit utilise le convertisseur numerique/analogique C (50) comme condensateur d'entree, eliminant ainsi le besoin d'utiliser un amplificateur tampon et permettant au convertisseur numerique/analogique (14) d'etre utilise a la fois pour la conversion analogique/numerique et la conversion numerique/analogique.

IPC: H02K7/18
Filed: 1983-03-31
Abstract: The method involves inducing a piston system, comprising two inseparably coupled pistons in two opposite combustion chambers, to perform mechanical straight reciprocating movements, a combustion process, initiated by an electric spark, taking place in the combustion chambers repeatedly in cycles at successive times, and the kinetic energy of the reciprocating movements of the movable parts being converted into electrical energy. The object is to make it possible for this to proceed at higher piston speeds and higher pressure, in order to make starting easier and to allow fuels of lower calorific value to be used. This is achieved by the combustion process commencing at a low compression stage, adequate for initial igniting of the fuel/air mixture when initiated by an electric spark, proceeding with a decreasing volume under the effect of the forces of the opposite combustion chambers and concluding with an increasing volume upon return of the piston, an electromotive voltage being induced in a coil which is attached in a fixed manner to the inseparably coupled pistons and, in its movement, crosses through the magnetic lines of flux of a fixed permanent magnetic field. <IMAGE>

Abstract: Electrophotographic copying machine comprising a photoconductive element, a charging device and an exposure device for forming a charge image, a developing device having a potential-carrying developing electrode for the image-wise application of electrically conductive marking particles onto the charge image, and control means (27,28,37,39,44) for adjusting the amount of light to be delivered by the exposure device and/or the potential of the developing electrode. For copying of high-contrast originals, the control means (27,28,37,39,44) can be set to a first setting corresponding to image-forming conditions which, after development, produce an image with a background which is substantially free of marking particles and for copying of low-contrast originals, the control means can be set to a second setting corresponding to image-forming conditions which, after development, produce an image with a background on which a considerable quantity of marking particles is deposited. Only when the setting means is set to the second setting, the developing electrode is connected to an a.c. voltage source (25,46) by means of a switching device (24,31), said a.c. voltage source generating an a.c. voltage at a frequency of between 1 and 7 kHz. As a result of this a.c. voltage the produced copies have a homogeneous background on which low-contrast information is readily visible.

Abstract: To mark carpets it is known to use marking fluids which produce invisible writing which is fluorescent under UV light; the fluorescent component is a water-soluble optical brightener which, despite fixing support from a dried-on copolymer dispersion, does not form a waterproof bond with the fibre. The invention provides for invisible, firmly adherent marking by using pigments which under UV or X-rays are perceivable directly by fluorescence or only indirectly by their exclusive action as X-ray detectable elements. Some of the pigments can be produced on/in the textile fibre by chemical reaction. For a marking which is to be exclusively X-ray detectable, the pigments used can also be glass or metal powders, or else solutions of X-ray detectable elements. The firm and washproof bond of the pigment particles to the fibre is effected or augmented by thermoplastic particles or film-forming synthetic resin, silicate or silicone solutions.
