Patent EP-0147386-A4 (EP)
Title: Regulator and switching circuit for flasher units.
Inventor: SEIDLER ROBERT L
IPC: G08B5/40
Filed: 1983-04-08
Abstract: A voltage regulator and switching circuit for a flash lamp control unit. A silicon transistor (92) is used to switch on an incandescent lamp (24) and to regulate the voltage across the lamp. A driver transistor (94) is connected to the switch transistor in a darlington connection with the collectors connected by a diode (93). During initial turn on of the lamp, its filament draws a heavy current furnished by the darlington circuit. As the filament heats, its current drops to a low value. Drive current then flows through the drive transistor and a resistor (95) to ground, reverse biasing the diode and changing the circuit to a single transistor circuit. The driver transistor is controlled by a differential amplifier (98, 99) having a first transistor biased by a first voltage divider network (103, 205) connected across the power supply and a second transistor (99) biased by a second voltage divider network (197, 201) connected across the regulated voltage. A zener diode (97) provides a fixed reference voltage to the first transistor when the supply voltage is greater than the regulated voltage, and the first voltage divider supplies a variable reference voltage when the supply voltage is less than the regulated voltage. The action of the differential amplifier in the latter instance prevents the switch transistor from saturating so as to maintain a preselected low voltage drop thereacross.

Abstract: Systèmes de suspension d'équipements vibratoires de manipulation de matériaux. Le problème posé par les dispositifs vibrants conventionnels servant à l'entraînement d'organes de travail est qu'ils manquent d'adaptabilité et qu'ils sont très complexes. Une solution à ce problème est constituée par un dispositif vibrant à torsion (10) fonctionnant en tant que système à deux masses vibrantes, se composant d'une première masse possédant un organe de travail généralement circulaire (32) et un mécanisme à ressort (12) reliant la première masse à la deuxième masse (27) excitée par un ou plusieurs poids excentrique(s) (14) entraîné(s) par un moteur, de sorte que la deuxième masse (27) vibre dans un cheminement circulaire possédant une composante circulaire et une composante verticale qui provoquent le transport dans un sens circulaire du matériau sur l'organe de travail (22). L'organe à ressort (12) est unique dans cette combinaison. Tout le système est isolé d'une structure de support (20). Le système peut être utilisé pour commander l'écoulement de matériau en vrac à partir d'une trémie (16), tamis (123) ou dispositif d'alimentation (222) ou bien pour faire circuler vers le haut ou vers le bas un matériau dans un entonnoir hélicoïdal (323), ou encore pour l'orientation de particules séparées (322), ou pour d'autres applications déterminées par une conception adéquate de l'organe de travail.

Title: Transit car door system and operation
IPC: E05F15/00
Filed: 1990-04-05
Abstract: A computer assisted transit car door operating system for augmented automation of transit car door panel (72, 74) operation while providing safety provisions to restrain rail movement unless all passage doorways are closed. A programmable logic controller (180) generates a sequence initiating (opening or closing) signal for a door panel (72, 74), or a manual input signal can be introduced for such prupose. The controller (180) receives signals from a panel position sensor (84, 85) and a panel movement sensor (88, 90) to evaluate door panel status and generate status indication and panel movement signals. Automated control of door panel movement is selectively directed to a doorway, or doorways, at which an opening or closing problem is being encountered; that is, the exclusion of door panel movement signals to properly operated door panels (72, 74). An electrical cam device utilizes a radiant energy emitter (604) and detector (606) with a reversible-direction, coded attenuator (600), keyed to a reversible-direction DC driving motor (76, 78) for a door panel (72, 74); modulating output of such radiant energy detector (606) indicates direction of movement and other data by coordination with the controller (180). An electrically controlled power switch (294) controls connection of a source of DC power to control direction of rotation of the reversible-rotation DC driving motor (76, 78) controlling opening and closing of a door panel (72, 74).

Filed: 1990-10-19
Abstract: This invention relates to a multi-purpose data processing method and apparatus which can be implemented at each step of production and transaction of articles such as ordering, production, shipment, and delivery of articles, billing and payment, for example. In the present invention, an output format designation signal which designates one of a plurality of output formats which have been in advance set and stored and a signal representing predetermined variable data in the output format are transmitted over a transmission line. On the reception side, the received variable data is written into the variable data area of the image of the output format on the basis of the output format designation signal and the variable data signal transmitted over the transmission line, and outputted and displayed as one image made two-dimensionally visual. Variable data is added to the received signal or the signal is partly corrected to be sent back to the transmission side, and the transmission side visualizes it and makes necessary addition or correction to variable data, thus providing bidirectional communication and data processing. According to this construction the load on the transmission line can be reduced and a transmission line having a small capacity can be used. Furthermore, multi-purpose data processing can be performed quickly.
