Patent EP-0057618-A1 (EP)
Inventor: FULMER KEITH HAROLD
IPC: F16D65/12
Filed: 1982-01-06
Abstract: A disc brake (10) includes a brake disc (12) having friction faces (14, 16) on opposite sides thereof. A caliper (36) straddles the brake disc (12) and cooperates with a pair of friction elements (60, 62) to urge the latter into engagement with the friction faces (14,16) to effect a brake application retarding rotation of the brake disc. The brake disc (12) includes a multitude of radially-extending passages (66) opening to the atmosphere at their radially inner ends and opening on the friction faces (14, 16) at their radially outer ends. Centrifugal force causes atmospheric air to flow through the radially-extending passages (66) in response to rotation of the brake disc. The air flowing from the passage openings on the friction faces (14, 16) provides a film of air between the friction elements (60, 62) and friction faces (14, 16) so that the friction elements (14, 16) do not drag on the brake disc (12) when the brake (10) is not applied.

Patent EP-0135613-A1 (EP)
Inventor: BINDER ALFRED
IPC: B23B45/02
Filed: 1983-10-20
Abstract: A method and apparatus for controlling an electric motor, in particular a motor for driving hand tools, saws, and the like, the rotational speed of which is automatically reduced in no-load idling operation and increased when working under load to pre-determined speed values corresponding to desired working speeds. A current sensor picks up the current absorbed by the electric motor and causes the speed of the electric motor to be abruptly changed when a load condition has been detected. A timing relay maintains the electric motor at the higher working speed for a pre-determined period of time after termination of the operation under load. The threshold value of the sensitivity of the current sensor is raised simultaneously with the change-over to the higher working speed.

Abstract: Sous excitation photoluminescente (PL), la propagation latérale de porteurs photoexcités peut supprimer le signal de photoluminescence provenant de plaquettes (12) à hétérostructure double (DH) contenant une jonction p-n. Dans toute DH avec une jonction p-n dans la couche active, la PL est supprimée si la puissance de la source d'excitation (16) ne dépasse pas une valeur seuil. Cet effet peut avantageusement être utilisé pour une détermination optique nondestructive de la conductance de la feuille supérieure de la couche de revêtement, ainsi que pour le mauvais positionnement des jonctions p-n, des paramètres importants relatifs aux DELs et aux lasers à injection. Le spectromètre (36) détecte la photoluminescence tandis que l'atténuateur variable (20) fait varier l'intensité de la source optique (16). Une courbe caractéristique intensité de photoluminescence/intensité de rayon d'excitation est produite par un enregistreur (38) sensible au signal de sortie du spectromètre (36) et au signal de sortie de l'atténuateur variable (20), telle que la perçoit le moniteur de puissance (26).

Abstract: Die Erfindung betrifft einen Sperrwandler-Schaltnetzteil, der mit einer durch Gleichrichtung der Netzwechselspannung erhaltenen Primärspannung Up versorgt ist. Da sich diese Spannung erfahrungsgemäß verändert, wird vermittels des Schaltnetzteils die zur Versorgung eines elektrischen Geräts dienende Sekundärspannung stabilisiert. Nun hängt die maximal zur Verfügung stehende Sekundärleistung im allgemeinen von der Primärspannung Up ab. Die vorliegende Erfindung hat nun die Aufgabe, diesen Nachteil der bekannten Schaltnetzteile zu beseitigen. Hierzu ist erfindungsgemäß eine über einen Spannungsteiler beaufschalgte Korrekturschaltung vorgesehen, wobei der Spannungsteiler an der Primärspannung Up liegt. Die Korrekturschaltung ist so ausgebildet, daß sie den Knickpunkt des Sedkundärstroms Is konstant hält. Dadurch ist es möglich, die sonst erforderliche Überdimensionierung gewisser Teile der Schaltung, vor allem des Transformators, des Wandlers und des Schalttransistors, zu ersparen, während sich andererseits die Erfindung mit geringem Aufwand realisieren läßt.

Abstract: An apparatus for the rapid and accurate dimensional inspection of an object. In particular, the apparatus is adapted for the acquisition of object range data. The apparatus includes a source for emitting a slender beam of radiation, first beam guide means (2) for causing the beam to impinge on a desired spot P of the object under inspection, second beam guide means (4,5) for causing radiation reflected from the spot of impingement on a linear radiation-sensitive detector (6,7) 
     A preferred embodiment includes third beam guide means for causing radiation reflected from the spot of impingement to traverse a further path also leading to the detector. 
     The second and third beam guide means are structurally different from each other in such a manner that one and the same object spot irradiated by the beam portion is imaged on the detector as two separate, focussed spots spaced a fixed distance from each other. Thereby a reliable discrimination can be made between true and false reflections from the object under inspection.
