In order to develop the floor-cleaning machine in such a way that the cleaning tool can be easily replaced, the invention proposes that said cleaning tool is adapted to be detachably latched to the tool holder and to be disconnected from the tool holder in the axial direction by means of an unlatching mechanism which is adapted to be operated by the user. | 09-11-2008 |
20130025076 | ROAD SWEEPER - A road sweeper is provided with a rotatingly drivable sweeping brush, a sweepings container, a suction blower in flow communication with the sweeping brush for taking in dust-containing air, and at least one filter for separating dust from the air drawn in, wherein the filter can be acted upon on the clean side with external air stored in a pressure container and subject to pressure, via at least one external air valve for cleaning. In order for the filter to be cleaned off with as small an amount of external air as possible, the pressure container can have a pressure container wall located opposite the clean side of the at least one filter, the at least one external air valve being arranged on the wall, wherein a section of a suction conduit extends between the pressure container wall and the clean side of the filter. | 01-31-2013 |

20110188689 | CONDUCTION DEVICE FOR A HEARING APPARATUS AND METHOD FOR PRODUCING A CONDUCTION DEVICE - A hearing apparatus, more particularly a hearing aid, generally requires sound or electrical signals to be conducted from a housing, worn outside of an auditory canal of a user, to an earpiece which has been inserted into the auditory canal. An appropriate conduction device often has a soft tube. The tube must be fixedly connected to the earpiece so that the latter can be pulled out of the auditory canal using the tube. Nevertheless, the connection between the tube and the earpiece is made detachable by an appropriate plug so that the earpiece can be cleaned. The plug is attached as securely as possible to the soft tube. One end of the tube and a region of the plug may be encapsulated by a material by insert molding or the tube and the plug may be welded together. A method for producing a conduction device is also provided. | 08-04-2011 |
20120328139 | BEHIND-THE-EAR HEARING AID HAVING A PLUG-IN CONNECTOR - A behind-the-ear hearing device has a housing with a plug-in connector on a sidewall of the housing for connecting to an earpiece tube or sound tube. The lateral arrangement of the plug-in connector moves the plug-in connector away from the exposed position on the front end face of the housing. This enables the front end face, which is generally visible, to be made smaller. Advantageously, at least two microphones are provided, with one microphone position in the vicinity of the front end face of the housing. The front microphone position is thus moved farther away from a position that may possibly be covered by the pinna, and the rear microphone position can also be moved farther toward the front. The microphone positions are thus approximately horizontal, which promotes the spatial resolution of the detected surrounding sound (directionality) by the signal processing of the hearing aid. | 12-27-2012 |
20130004005 | CONNECTOR FOR A HEARING INSTRUMENT AND HEARING INSTRUMENT - A connector for a hearing instrument, in particular a receiver-in-canal behind-the-ear hearing aid, is small and visually inconspicuous. The connector should be as invisible as possible on the hearing instrument as it is worn, and the connector allows a microphone arrangement favorable for directionality and sound pick-up. The connector is disposed on an earpiece tube, which defines a longitudinal direction at the connector. The connector is connected by insertion into a connector receptacle of a hearing instrument transversely to the longitudinal direction. The hearing instrument has a laterally arranged connector receptacle, into which a connector is inserted transversely to the longitudinal direction. Because of the transverse insertion, the connector can be arranged laterally on the housing and because of the lateral placement, the front end face of the housing is smaller and the housing is overall flatter. A microphone can be arranged on the end face instead of the connector so as to improve sound pick-up and directionality. | 01-03-2013 |

20140205120 | HEARING INSTRUMENT HOUSING HAVING A PLUG-IN CONNECTION, PLUG AND HEARING INSTRUMENT - A hearing instrument has housing with a plug-in connection. The plug-in connection connects hearing tubes, sound tubes or electrical signal lines. The hearing instrument ensures against an unintentional detachment of the tubes and lines from the housing. The housing has a locking apparatus. The plug-in connection is arranged in the housing. The locking apparatus is embodied to prevent an unintentional detachment of the plug in the plug-in connection. The locking apparatus includes a catch, with a latching plate, and being moveably mounted in the housing. The catch moves at right angles to the plug-in direction of the plug and the latch is pushed into the housing and is protected herein by a blocking facility against unintentionally being pushed out. The blocking facility includes a stop and a blocking element, against which the stop strikes when sliding out. With the moveable catch, an easy-to-operate locking process is achieved. | 07-24-2014 |
20150086053 | HEARING INSTRUMENT WITH BATTERY COMPARTMENT SWITCH - A hearing instrument has a battery compartment switch which causes the hearing instrument to switch on/off. An electrical contact to the battery is established and interrupted by the battery compartment switch when the battery compartment is closed and opened. An on/off contour in the area of the battery compartment and a correspondingly shaped battery contact device are provided, the configurations are tailored, so that the lift-off area for lifting the battery contact device away from the battery and the contact area of the battery contact device are separated from one another. The battery contact device has a lift-off area and a contact area. Both areas are configured separately to reduce the wear on the on/off contour and to secure electrical contacting of the battery. This enables a lift-off area with a large surface, through which the mechanical pressure on the on/off contour is distributed and is thus reduced. | 03-26-2015 |

20080257282 | Fossil-Fuel Heated Continuous Steam Generator - The invention relates to a fossil-energy heated continuous steam generator, whereby the at least one combustion chamber, viewed in the flow direction of the hot gases, is divided into at least two throughflow segments, formed by evaporator heating surfaces, whereby the evaporator heating surfaces each comprise steam generation tubes welded to each other in a gastight manner and pressurized in parallel with a flow medium. According to the invention, said generator is suitable for operation with high fresh steam parameters, such as for example, steam temperatures of approximately 700° C., with a simple construction and particularly simple assembly, whereby a throughflow segment, arranged after the first through flow segment, viewed in the direction of flow of the hot gases, forms the first evaporator stage for the flow medium, such that the injection of particularly cold flow medium can occur in the region of maximum heating. | 10-23-2008 |
20090071419 | Steam Generator - The invention relates to a steam generator wherein a continuous heating panel of a generator, which is formed from a number of evaporator tubes, and an overheating panel, which is formed from a number of over-heating tubes which are arranged downstream from the evaporator tubes and on the flow side, are arranged in a heating gas channel. According to the invention, a water separating element is integrated into a number of over-flow tubes which are connected on the flow side of one of several evaporator tubes to one or several overheating tubes. | 03-19-2009 |
20110011090 | METHOD FOR STARTING A CONTINUOUS STEAM GENERATOR - A method for starting a continuous steam generator is provided. The steam generator includes a combustion chamber provided with a plurality of burners, a water-steam separation device that is mounted downstream of evaporator tubes of the water-steam separation device on a flow-medium side. The amount of water flowing into the water-steam separation device during a starting process is kept to a minimum. The firing power of at least one of the burners is adjusted in accordance with a filling level characteristic value of the water-steam separation device. | 01-20-2011 |
