20110080159 | Method for Testing the Operation of a Heating Element Used for an Activated Carbon Filter - The invention relates to a method for testing the operation of an electric heating element which is used for heating activated carbon of an activated carbon filter and/or air which is guided through the activated carbon for the regeneration thereof. The heating element has a PTC-characteristic (positive temperature coefficient characteristic). The strength of a current flow through the heating element in a heating phase selected for the operational testing is measured at a point in time or over a time period and is used for the operational testing, in that at least one measured current flow value is compared with a corresponding current flow value to be anticipated during defect-free operation of the heating element, and the heating element is considered to be defective in the event of a deviation which exceeds a predetermined measurement. | 04-07-2011 |
20110089680 | Insertion Coupling - An insertion coupling which can be used for example for a vacuum line consists of an insertion part and a sleeve part (1), wherein a locking element (5), which can be brought into engagement with a retaining rib of the insertion part, and an actuation element (10) are integrally formed on a housing tab (9) which extends in an arc-shaped manner around a longitudinal axis of the sleeve part (1) and can be elastically deflected radially. A movement of the locking element (5) in a radially outward direction and thus a release of the engaged state between the sleeve part (1) and the insertion part is possible by moving the actuation element (10) in an actuation direction (13). A construction which is particularly simple in design is produced owing to the small number of parts. The sleeve part (1) is provided with a window, by means of which a correct engaged state of the locking element with the retaining rib can be visually checked. | 04-21-2011 |
