Abstract:
The invention concerns a device (10) comprising at least a wave emitter (12) such as visible light waves, and at least a wave receiver (13) sensitive to the emitter (12) waves. The emitter (12) and the receiver (13) are connected by a tubular element (14). The device further comprises means (15) for measuring variations in the intensity levels of the waves received by each receiver. When the tubular element (14) is not deformed, the receiver (13) receives a known intensity level. When the tubular element (14) is deformed, the intensity level received by the receiver (13) is different from said known intensity level. Said difference is interpreted so as to control a member such as a motor, an actuator or a meter.
Abstract:
The invention relates to an actuating device (1) for regulating a control mechanism which is subjected to a force against the direction of regulation (6). Said actuating device comprises a drive device (3) which has a drive shaft (2) and is connected in a moveable manner to a rotating spindle (4), by which means an actuating element (5) can be axially displaced in the direction of regulation (6), in a housing (7) receiving the device. The aim of the invention is to improve one such actuating device in such a way that actuation of the control mechanism is guaranteed in a constructively simple and cost-effective manner. In order to achieve this, the drive device (3) comprises at least two electric motors (8, 9) which can respectively be actuated and controlled for the rotation of the drive shaft (2).
Abstract:
The invention relates to an actuating device (1) for displacing a control device (3), against a force in the opposing direction (2) to the displacement, comprising an operating element (7) in a device housing (4), which may be axially displaced, at least in the direction of displacement by means of a feed mechanism (6). In order to improve said actuating device such that it may be simply operated without any impairment in emergency, when, for example the energy supply fails, or other problems occur, said actuating device comprises an emergency actuator, which may be externally operated and which may be connected to the feed mechanism (5) by means of a directional coupling device.
Abstract:
Die Erfindung befasst sich mit Verbesserungen auf dem technischen Gebiet der Stellantriebe. Hierzu wird unter anderem ein Fail-Safe-Antrieb (1) für einen Stellantrieb vorgeschlagen, der einen Antriebsenergiespeicher (6) aufweist, der zumindest eine Tellerfeder (7) und eine Kurvenscheibe (8) zur Umwandlung einer axialen Antriebsbewegung eines Rückstellelements in eine rotatorische Antriebsbewegung umfasst.
Abstract:
The invention relates to an actuating device (1) for displacing a control device (3), which is subjected to the action of force counter to the direction of displacement (2). Said actuating device comprises an actuating element, which, inside a device housing (4), can be axially displaced in a direction of displacement by a turning spindle (5) of an advancing device (6). The turning spindle is connected in a rotationally fixed manner to a turning sleeve (8), which is rotatably mounted in the device housing (4) and which surrounds the turning spindle. Said turning sleeve is fixed, in relation to an annular flange (9) that is connected to the device housing in a rotationally fixed manner, counter to an advance turning direction (11) of the turning spindle by means of a spiral spring (10). An emergency disengagement device for resetting the actuating element counter to the direction of displacement is assigned to the spiral spring. The aim of the invention is to improve the actuating device by providing it with a compact and simple design and, at the same time, by enabling the winding of the spiral spring to be easily and precisely adjusted with regard to the torsional strength of the connection of the turning sleeve and the annular flange. To this end, the emergency disengagement device comprises a tension sleeve (13) for the spiral spring that is detachably held in a tensioning position. Said tension sleeve can be torsioned between a tensioning position and a final tensioning position and is subjected to the action of force toward its final tensioning position.

Abstract:
The device comprises a detection arm (7) pivotally placed in the fuel chamber (1) of a heater (20), wherein the end portion (7.1) of the detection arm (7) defines the level of the residual layer (8) of fuel (2), wherein the detection arm (7) is connected to a detection deflection element (4). The detection deflection element (4) comprises an outer arm (10) which is firmly connected to the detection arm (7), wherein the outer arm (10) is led out of the fuel chamber (1), and wherein a weight (11) is attached to the outer arm (10). The outer arm (10) is connected to a position sensor (6) or an air flap. From the point of view of comfort loading of fuel to the fuel chamber (1), a pressing element (16) is associated with the detection deflection element (4). The pressing element (16) comprises a cam (15) added to the outer arm (10), wherein the cam (15) is connected to the loading door (12) by means of a rod (14).
Abstract:
A method and apparatus for efficiently using media stamped on a substrate including a nip and pull rollers (40a, 42a), a shuttle (50), a cylinder (10), and a control arrangement. The media (3) has at least one registration mark. The nip and pull rollers (40a, 42a) is coupled to the media (3) and provides the media (3) with a first velocity component. A shuttle (50) is coupled to the nip and pull rollers (40a, 42a) via the media and moves linearly with a variable periodic velocity. By way of providing the media (3) with differing velocities, the nip and pull rollers (40a, 42a) and shuttle (50) working in conjunction with the cylinder (10) are able to efficiently utilize the media (3) from which transfer impressions are placed upon the substrate web (5).
