Patent EP-0841347-A1 (EP)
Inventor: HALL JAMES E
IPC: C08G85/00
Filed: 1997-10-15
Abstract: The invention is a practical process for anionically
synthesizing commercially significant quantities of macrocyclic
polymers from polar and/or non-polar monomers by using Group IIA
and IIB metal cyclic organometallic initiators. Activation of
the ring metal atom results in anionic polymerization of the
monomers by addition into the initiator ring at the bonds
between the atom and its two adjacent carbon atoms, the metal
atom acting as a bridge between the two living ends of the
propagating chain. Coupling of the cyclic polymer living ends
by coupling agents produces macrocyclic polymers that are stable
in air and moisture and that exhibit desirable properties, such
as low viscosities at high molecular weights. Such macrocyclic
polymers provide enhanced polymer processability during molding,
extruding and the forming of films. Macrocyclic polymers
terminated with coupling agents that also provide functional
groups may be compounded to produce vulcanizable elastomeric
compounds and articles that exhibit reduced hysteresis
properties.

Abstract: A process and apparatus are described for regulating
the concentration and distribution of oxygen in a single
crystal silicon rod (21) pulled from a silicon melt (23),
optionally doped with antimony or arsenic, in accordance
with the Czochralski method wherein an atmosphere is
maintained over the melt (23). In batch embodiments of
the process, the gas pressure of the atmosphere over the
melt (23) is progressively increased to a value in excess
of 100 torr (13.33 kPa) as the fraction of silicon melt
(23) solidified increases. In continuous embodiments of
the process, the gas pressure of the atmosphere over the
melt (23) is maintained at or near a constant value in
excess of 100 torr (13.33 kPa). The process and
apparatus are further characterized in that a controlled
flow of inert gas is used to remove vapors and
particulate away from the surface of the rod (21) and
melt (23), resulting in the production of a single
crystal silicon rod (21) having zero dislocations.

Abstract: The detecting method described is conceived for use in a
bar code decoding system based on digital processing of
signals. It functions to process in real time a signal from
an A/D converter and determine the portions of this signal
which contain a likely bar code and rejecting the portions
that surely do not contain a code. Only the former are
signaled to a subsequent decoding process. The method steps
are essentially the following:
     A) determining local maxima and minima of the
digitalized analog signal;   B) determining valid transitions;   C) calculating the size of constant brightness zones
located between two successive valid transitions;   D) determining likely codes;   E) if appropriate, re-positioning the code starting
zone;   F) if appropriate, analyzing detected potential codes
for congruence, and signaling the likely codes.

Abstract: A water-containing polyolefin resin composition
containing a polyolefin resin and a hydrophilic polymer
and having a water content of 1 to 50 % by weight, which
is suitable for use in preparation of polyolefin resin
pre-expanded particles, and pre-expanded particles of a
polyolefin resin prepared by pre-expanding this water-containing
polyolefin resin composition and having a an
apparent expansion ratio of 5 to 60, a closed cell ratio
of 80 to 100 % and an average cell diameter of 50 to 500
µm. The pre-expanded particles can be prepared without
using a volatile blowing agent by dispersing resin
particles made of a polyolefin resin composition
containing a polyolefin resin and a hydrophilic polymer
into an aqueous dispersion medium in a closed vessel to
form a dispersion, heating to a temperature of not lower
than the softening point of the polyolefin resin to give
water-containing resin particles having a water content of
1 to 50 % by weight, and releasing the aqueous dispersion
from the closed vessel into an atmosphere of lower
pressure than the inner pressure of the closed vessel,
thereby expanding the water-containing resin particles.
When the releasing of the dispersion from the vessel is
conducted after raising the inner pressure to 25 to 75
kg/cm 2 G by introducing nitrogen gas, air or an inorganic
gas composed of them as a main component into the vessel,
pre-expanded particles capable of providing foams having
good physical properties and a high expansion ratio can be
obtained.

Abstract: The conveying method comprises a flying takeover of containers (1) being fed into a takeover area (U.1) in a container stream, hanging conveyance of the containers along a conveying path (FS) with a freely selectable course and delivery of the containers in a delivery area (U.2). For taking over the containers, a sequence of individual and equidistant holding means (5) is supplied to the takeover area (U.1) along a descending curved path (7') joining a container feeding path (8) tangentially at the end of the takeover area (U.1) and the holding means (5) are introduced into the container stream each between two containers (1). At the beginning of this introduction, the holding means have a speed (v') greater than the container speed (v) and during introduction they are decelerated to the container speed (v). Thereby, the feeding of containers and holding means is matched such that each holding means (5) reaches the container feeding speed (v) when it encircles the container downstream, i.e. when it is in an at least potential holding position relative to this container. At the latest in the delivery area, the holding means are turned by 180° around a vertical axis such that for delivery the containers to a container removing means (11), the holding means (5) can be conveyed away along an upward curved path. The curved path of the holding means in the takeover area (U.1) and/or in the delivery area (U.2) may also be realized by individual pivoting of the holding means (5).

Abstract: Un syntoniseur automatique destiné à des systèmes de commande produit des valeurs de sortie pour les paramètres d'un controleur arbritaire. Le contrôleur se trouve dans une boucle d'asservissement de sorte que sa sortie produit des changements dans des actuateurs et régule un processus physique. Le contrôleur se compose de composants soit linéaires soit non-linéaire, soit d'une combinaison des deux. Le syntoniseur présente une unité d'approximation non linéaire ayant été optimisée en autonome. L'optimisation en autonome est effectuée sans apprentissage supervisé de sorte qu'il n'est pas nécessaire que les sorties du réseau neuronal soient disponibles, et une optimisation séparée pour générer les sorties voulues n'est pas nécessaire. L'optimisation en autonome peut également se baser sur des critères d'optimisation arbritaires: différentiabilité, convexité, continuité régulière de critères ne sont pas requises. L'optimisation en autonome assure la robustesse des paramètres générés du contrôleur de sorte que les caractéristiques de traitement d'entrée ne nécessitent pas une extrême précision. L'optimisation en autonome est effectuée de manière que les paramètres d'entrée relatifs au comportement voulu du système à boucle fermée comprennent des paramètres de robustesse pouvant être utilisés pour effectuer des substitutions entre les performances de robustesse et nominale. Les entrées dans l'unité d'approximation non linéaire se composent de deux ensembles de paramètres d'entrée, dont chacun peut être vide. Un premier ensemble de paramètres d'entrée peut comporter des paramètres relatifs aux caractéristiques de processus. Un second ensemble de paramètres d'entrée peut comprendre des paramètres relatifs au comportement voulu du système à boucle fermée. Les valeurs de sortie peuvent être des gains proportionnels et/ou intégraux et/ou dérivés pour des contrôleurs de type PID (proportionnel-intégral-différentiel). Les valeurs de sortie peuvent également être des paramètres pour des contrôleurs à compensation de temporisation, des paramètres pour contrôleurs se composant de termes d'avance-retard en combinaison avec des contrôleurs PID, des paramètres pour contrôleurs linéaires d'ordre supérieur, des valeurs discrètes sélectionnant différentes structures de commande, ou des paramètres pour contrôleurs non-linéaires de structure prédéterminée. L'unité d'approximation non-linéaire peut être mise en oeuvre sous la forme d'un mappage sigmoïde compositionnel, d'une structure de perception multicouche, d'un modèle de logique floue, d'un réseau de fonction à base radiale, d'une expansion polynomiale ou d'un autre structure non-linéaire paramétrée.

Title: Sensorless step recognition process for stepping motors
Inventor: HARTZSCH JOERG
IPC: H02P8/38
Filed: 1997-07-21
Abstract: A process is disclosed for recognizing the step of stepping motors by analyzing the current that flows through the motor, without using any sensors. In order to overcome the problems caused by the use of a shunt resistance, the resulting current measurement errors and toggling, and to ensure an as disturbance-free and reliable operation as possible in all operation states of both unipolar and bipolar stepping motors, the disclosed process has the following steps: a defined current is transmitted to a motor winding after a reversal of the current flow direction in a first motor winding; a motor winding connection is switched with a high ohmic value; the response signal at the motor winding connection switched with a high ohmic value is sensed; the length of the response signal is evaluated. Alternatively, triggering is provoked by an external triggering signal, independently of the reversal of the current flow direction.

Abstract: L'invention concerne un système et un procédé d'imagerie en trois dimensions. Le système comprend une lentille (34), qui effectue une transformation de Fourier bidimensionnelle d'un diagramme d'interférence en focalisant ledit diagramme sur un réseau détecteur bidimensionnel (40) positionné dans le plan d'image (38) de la lentille. On peut ainsi pré-visionner immédiatement l'objet imagé afin de le positionner correctement. Des faisceaux cohérents sont utilisés pour créer une série de diagrammes d'interférence ou des hologrammes de plan d'image, à une fréquence différente de celle des faisceaux de la source. A chaque fréquence, on fait varier la phase relative entre un objet et un faisceau de référence afin de capturer les valeurs complexes associées aux diagrammes d'interférence. Après avoir capturé et mis en mémoire les différents diagrammes d'interférence, un ordinateur (42) effectue une transformation de Fourier unidimensionnelle ou un autre traitement simplifié afin de générer l'image tridimensionnelle de l'objet. La résolution de l'image peut aller jusqu'au micron, ce qui permet d'adapter facilement ce système et ce procédé à diverses applications de contrôle tridimensionnel.
