Patent EP-0452417-A1 (EP)
Inventor: WIBLIN WAYNE T
IPC: H01H47/00
Filed: 1990-01-20
Abstract: Système (16) pour affaiblir le courant dans une bobine (22). Un commutateur (28) doté des deux positions "MARCHE" et "ARRET" commande le niveau du courant dans la bobine (22) et un circuit de retour (48) permet au courant se trouvant dans la bobine (22) de se dissiper lentement lorsque le commutateur (28) passe de la position "MARCHE" à la position "ARRET" ce qui évite alors les pointes de tension qui peuvent créer des dommages. Losque le commutateur (28) passe de la posistion "MARCHE" à la position "ARRET", le circuit de retour (48) possède une forte résistance qui permet d'affaiblir le courant de la bobine (22) aussi rapidement que possible sans créer une tension destructrice; une résistance faible sert à conserver l'énergie lorsque le commutateur (28) est en position "MARCHE". Un dispositif de signalisation (60) crée un signal de tension sous forme d'une fonction de courant traversant le circuit de retour (48) et un dispositif de réception (44) fait varier la résistance du circuit de retour (48) en réponse au signal de tension. Le système (16) est plus particulièrement adapté pour être utilisé dans un circuit de commande du moteur (10).

Date Apr. 18, 1991.A method of transmitting an analog signal including the steps of converting the analog signal into a digital signal and using windows to subdivide the digital signal into successive blocks. The blocks are evaluated for level changes, and when a level change is below a predetermined level the blocks are overlapped by 50%. The signal segments within the blocks assessed using analysis windows. The signal segments are transformed using subsampling and time domain aliasing cancellation to compensate for aliasing components. The signal segments are inverse transformed and assessed using synthesis windows. The blocks are rejoined in overlapping fashion. When the level change is above the predetermined level the signals are subdivided into blocks and the blocks are overlapped by less than 50%, or not overlapped at all. The signal segments are fully scanned, compressed and transformed. The signal segments are finally inverse transformed and expanded.

Title: Nähautomat zum Annähen von Bändern an Stoffteile
Inventor: MUELLER ERNST
IPC: D05B35/06
Filed: 1991-05-31
Abstract: Bei einem Nähautomaten zum Annähen von Bändern an Stoffteile ist eine das Band dosiert liefernde Dosiervorrichtung (3) elektronisch mit der Nähmaschine über einen als Impulsgeber ausgebildeten Weggeber (6), eine Signalverarbeitungsschaltung (8) und einen Motor, z.B. Schrittmotor (SM) gekoppelt. Die von der Dosiervorrichtung gelieferte Bandmenge pro Zeiteinheit hängt von der Drehzahl ab. Andererseits ist die Stichlänge der Nähmaschine jedoch nicht unabhängig von der Drehzahl, sondern wird mit zunehmender Drehzahl größer. Die dadurch entstehenden, unerwünschten Spannungen zwischen Stoffteil einerseits und Band andererseits werden vermieden durch eine Korrektureinrichtung (10) zwischen dem Impulsgeber (6) der Nähmaschine (2) und der Treiberschaltung (12) des Schrittmotors (SM) der Dosiervorrichtung (3). Die Korrekturvorrichtung sorgt dafür, daß die an die Treiberschaltung (12) gelangenden Steuersignale bei höheren Nähmamaschinendrehzahlen eine korrigierte, überhöhte Dosierung des Bandes bewirken. Diese Korrektur ist nicht nur bei Bändern möglich, sondern allgemein bei Elementen, die abhängig von der Drehzahl des Maschinenantriebs relativ zum Drückerfuß transportiert werden. <IMAGE>

Abstract: A layered photosensitive imaging member (14) is modified to reduce the effects of interference within the member caused by reflections from coherent light incident on a base ground plane (24). The modification described is to form the ground plane surface with a rough surface morphology.by various selective deposition methods. In one method the metal forming the ground plane is deposited through a fine mesh screen which is either held stationary during a single pass or alternatively vibrated at a specific frequency during a single pass of deposition. Light reflected from the ground plane formed with the rough surface morphology is diffused through the bulk of the photosensitive layer breaking up the interference fringe patterns which are later manifested as a plywood pattern on output prints made from the exposed sensitive medium.

Calcium sulfate (25) is added to the portion of aqueous discharge at the oxidizer (17) to form an oxidized aqueous effluent containing calcium sulfate solids and dissolved magnesium sulfate. The oxidized aqueous effluent is regenerated by addition of lime, in a regeneration tank (31), which precipitates calcium sulfate as gypsum, with gypsum (43) returned to the oxidizer as the calcium sulfate added thereto. Preferably, the aqueous discharge from the oxidizer (17) is divided, with a major portion passed to a separator (59) to remove gypsum, therefrom, while a minor portion is passed to the regeneration tank (31). Magnesium sulfate solution (63), after separation of gypsum (61) from the major portion may also be fed to the regeneration tank (31).

Abstract: An inducible promoter is used to regulate expression of a gene which is known to be critical in microsporogenesis, i.e., the production of pollen. The selected gene's control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene.
