20130221207 | OPTICAL SENSOR AND TEST METHOD FOR TESTING THE OPERABILITY OF AN OPTICAL SENSOR - The invention relates to a test method for testing the operability of an optical sensor for monitoring a monitored zone in which at least one test object is used which is located in a detection zone of the sensor including the monitored zone. Provision is made in accordance with the invention that the test object is changed during the carrying out of the test method with respect to its position, alignment or its optical properties and produces a test signal when the change cannot be detected in the expected manner. The invention further relates to an optical sensor for monitoring a monitored zone, wherein the test method in accordance with the invention can be used. | 08-29-2013 |
20130222805 | OPTICAL SENSOR - The invention relates to an optical sensor for monitoring a monitored zone having a detection device for observing a detection zone including the monitored zone, said detection device including a transmission device for transmitting transmission light into the detection zone and a receiver for receiving light reflected back or remitted back from the detection zone or transmitted through the detection zone and having at least one test object within the detection zone of the optical sensor. In accordance with the invention, the optical sensor has a device for avoiding and/or eliminating the contamination of the at least on test object. | 08-29-2013 |
20130235379 | ATTACHMENT FOR PLACEMENT ONTO AN OPTICAL SENSOR AND METHOD OF OPERATING AN OPTICAL SENSOR - The invention relates to an attachment for placement onto an optical sensor having a housing with an inlet opening for the entry of detection light into the attachment, a test light receiver for receiving light incident at the test light receiver and for a power measurement of the light incident at the test light receiver as test light and having a signal outputting device for outputting an output signal correlated to the test light power. The invention moreover relates to a combination of an optical sensor and such an attachment and to a method for operating an optical sensor which method can be carried out with such an attachment. | 09-12-2013 |

20090133396 | HYDRAULIC CIRCUIT ARRANGEMENT WITH A DEVICE FOR LIMITING CONTROL AND METHOD FOR PRESSURE CONTROL BY CONTROLLING DISPLACEMENT - The invention relates to a hydraulic circuit arrangement for setting the delivery volume of a pump, with an electrically activatable control-valve unit, by means of which, alternately, an active side of a servo system can be acted upon with pressure and, at the same time, its passive side can be relieved to the tank, and with a device for pressure limiting pressure regulation, which comprises pressure limiting valves, by means of which the working lines of the pump can be connected to the servo lines. To reduce the servo pressure load and improve the reaction time, check valves which shut off in the direction of the servo system are provided, by means of which the two servo sides can be connected in each case to the charge pressure via a relief line. Moreover, the device for Pressure limiting pressure regulation comprises an orifice which can be positioned in a line leading to the passive servo side. The invention relates, furthermore, to a method for pressure. | 05-28-2009 |

20080245224 | ADJUSTING UNIT FOR AN AXIAL PISTON MACHINE - The invention relates to an adjusting unit for an axial piston machine, having a valve unit for controlling the oil pressure which loads a servo system, the valve unit having a substantially cylindrical valve slide which can be displaced along its centre longitudinal axis in the valve unit. On both sides of a plane of symmetry which is perpendicular with respect to the centre longitudinal axis, the valve slide has flattened portions which extend on the cylindrical outer cover parallel to the centre longitudinal axis and are delimited by control edges, as a result of which the connections to the two servo sides are controlled in such a way that, in a centred neutral position of the valve slide, the servo system is put into neutral and, when the valve slide is displaced from its centred neutral position, a different hydraulic pressure acts on the two servo sides which displaces the servo piston or the servo pistons correspondingly. A groove which reinforces the self-centring action is sunk in the flattened portions of the valve slide in the region of the respective control edge which lies to the side of the plane of symmetry. | 10-09-2008 |
