Publication number: 20100092274Abstract: The present invention shows a transport system for the transport of bulk goods, in particular of concrete, comprising a transport belt for the conveying of the bulk goods to an unloading point, wherein a rotary arm is provided which is rotatable about a vertical axis of rotation and which transports bulk goods to its free end and unloads them there. In this respect, the rotary arm is supported at a holder which is or can be arranged at a stationary support column such that the axis of rotation of the rotary arm extends eccentrically to the support column, with the rotary arm advantageously being arranged next to the support column, viewed from above, in at least one rotational position. The invention furthermore shows a corresponding support column as well as a method for the rebuilding of the transport system.Type: ApplicationFiled: October 9, 2009Publication date: April 15, 2010Applicant: LIEBHERR-MISCHTECHNIK GMBHInventors: Fabian RUDNER, Arthur HALDER

Patent number: 5969243Abstract: The invention relates to a humidity sensor for capacitive measurement of the humidity contained in a material, predominantly a bulk product. For parallel operation of several humidity sensors, one individual humidity sensor has to fulfil particularly high requirements with regard to accuracy, sensitivity and interchangeability. These requirements are fulfilled by the humidity sensor as per the invention firstly in that at least one pole of a stray field condenser arranged in the humidity sensor is fitted as a conductive layer on the side of a closer plate in the casing of the humidity sensor which is turned away from the material or bulk product. Furthermore, there is arranged in the casing a digital arithmetic-logic unit which exhibits a calibration table stored in a digital memory for determination of humidity levels as a function of measurement signals in a capacity measurement circuit which measures the capacity of the stray field condenser and of interference values affecting the humidity sensor.Type: GrantFiled: August 5, 1997Date of Patent: October 19, 1999Assignee: Liebherr-Mischtechnik GmbHInventors: Werner Frey, German Gotz
