Patent EP-0367871-A1 (EP)
Inventor: GILLILAND JOHN WILLIAM
IPC: C03B37/014
Filed: 1988-11-07
Abstract: A method is disclosed for making a step-index optical fiber having a steep refractive index gradient between core and cladding. Core glass particles comprising a base glass and a refractive index-­increasing dopant are deposited on a mandrel (20). The mandrel is removed and the resultant soot preform is consolidated to form a core preform (40) having a dopant-poor surface region. The core glass preform is stretched and the hole therein is closed to form a core bait rod. Cladding glass soot is deposited on the core bait rod at a density which is at least 0.5 g/cc. This is accomplished by directing the flame from an auxiliary burner (66) onto the core bait rod immediately prior to the deposition of cladding soot thereon. The resultant preform is consolidated and drawn into an optical fiber. In another embodiment, the etched core preform is overclad with a layer of cladding glass, and the composite preform is stretched prior to applying a second overclad layer.

Abstract: Un système d'ordinateur à noeuds multiples comprend des noeuds de processeur, des noeuds de mémoire, et des noeuds d'entrée/sortie interconnectés sur un bus (25) du type à déplacement vers la queue de la file d'attente. Le système comprend un indicateur de verrouillage (240) qui est mis en fonction lors de la réception d'un message de réponse verrouillée par un noeud de processeur provenant d'un noeud de mémoire en réponse à une commande de lecture d'asservissement. Les processeurs comprennent un circuit de contrôle de verrouillage (250) sensible à l'état de l'indicateur de verrouillage (240) et limite la génération de commande supplémentaire de lecture d'asservissement selon un critère de déclenchement d'accès prédéterminé jusqu'à ce que l'indicateur de verrouillage soit remis à l'état initial. De cette manière les noeuds processeurs du système sont assurés d'avoir un accès équitable à un noeud mémoire.

Abstract: The device for testing the strength of a loop (F) of binding twine round a pressed bale (B1) contains a sensor (4) located in the run-off path of the knots behind the knotter (2), so that the knot sensor (4) positively seizes each finished knot. The knot sensor (4) is made fork-shaped and is movably mounted in a spring-loaded manner, so that only a firm knot and a closed loop (F) of binding twine ever remain within a predetermined bale-transport distance in the knot sensor (4), this being monitored by means of a cam-controlled switching contact (33) and being evaluated so as to lead to the signalling of an alarm. <IMAGE>

Abstract: High molecular weight polyester resins such as polyethylene terephthalate, are sometimes produced from low molecular weight polyester prepolymers having the same composition by solid state polymerization. The low molecular weight polyester prepolymers which are used in such solid state polymerizations are normally prepared by conventional melt polymerizations and are generally in the form of pellets or chips. Solid state polymerization rates can be greatly improved by utilizing polyester prepolymers which are in the form of porous pills. By utilizing polyester prepolymers that are in the form of porous pills, higher molecular weights can be achieved after shorter solid state polymerization times. 
     This invention relates to an improved process for solid state polymerizing porous pills which are made by compacting fine fibers of the polyester prepolymer. The present invention specifically relates to a process for making porous pills by compacting fibers of polyester prepolymer which have a diameter of less than about 841 microns.

Abstract: In a catheter system for transmitting laser beams into vessel systems of the human body, the individual light-conducting fibres (3) at the distal light-emergence end of the annular catheter are designed to be expandable so that the circumference of the catheter can be increased and so that, therefore, it is also possible to effectively eliminate deposits in the vessel system which lie essentially beyond the diameter of the annular catheter. By means of expansion chamber arrangements which can be acted upon with pressure fluid, or preferably by means of a miniature dilatation catheter (9) which can be introduced into the inner channel of the annular catheter, the distance between the individual light-conducting fibres of the light conductor crown or between defined circumferential groups of light-conducting fibres of the crown at the distal end can be increased. These circumferential groups can be acted upon selectively with laser light by coordination of diaphragms at the hexagonally most compact packing of the light-conducting fibres at the proximal end of the catheter. <IMAGE>

Abstract: The device contains a radiation emitter (MSK) for the production of a measuring beam which passes through the stream (RS) of smoke and a receiver (MEK) for evaluating the attenuation of the measuring beam caused by the turbidity of the smoke. First holding means (OS,US;GE) connect the radiation emitter and the receiver in such a way that they lie opposite one another as in an optical bench. The device furthermore comprises a measuring tube (MR), to which the smoke to be evaluated is preferably supplied in the centre, escaping at two opposite outlet ends (AE1,AE2). There are moreover second holding means (GB), which hold the measuring tube on the first holding means in such a way that it can be pivoted. The measuring tube can thereby be pivoted into a first position (Figure 1), in particular a measuring position, between the emitter and the receiver. In this position, the axis of the measuring tube should as far as possible coincide with the axis of the measuring beam. It is thereby furthermore made possible to pivot the measuring tube (MR) out of the area between the emitter and the receiver (MSK,MEK), into a second position (Figure 2), in particular a servicing position. <IMAGE>

Abstract: A method is described according to which particles present in a fluid are separated from flakes adhered thereto. According to prior art separation takes place with the help of an ultrasonic field applied to the fluid. It appeared that a better separation is achieved, if the flakes are subjected to a substantial velocity gradient. This velocity gradient subjects the particles to shearing forces causing an effective separation of the elements. 
     Tests have shown that a pump generates such velocity gradients, that a most effective separation is achieved.
