Abstract: Hearing apparatus and especially hearing devices are to be designed to be smaller. To this end there is provision for the shell or otoplastic to be worn in the auditory canal or for the housing of the hearing apparatus to be made of battery layers, so that the shell or otoplastic or the housing of the hearing apparatus itself represents the battery. Alternatively the hearing device battery can also be relocated from a conventional hearing device into a normal otoplastic, with this also reducing the volume of the hearing device. The reduction in volume allows the acceptance of wearing the hearing device to be greatly increased, and a variant of the hearing apparatus can be more easily implemented as a cymba device.

Abstract: The invention relates to a method for soldering an all-aluminum heat exchanger, particularly a coolant radiator (1) for motor vehicles with a collecting reservoir (2) inside of which an additional heat exchanger (4), particularly a transmission oil cooler is placed. The invention also relates to a heat exchanger produced according to this method. The invention provides that the additinal heat exchanger (4) is, according to the so-called Nocolok® method, firstly soldered separately in a vacuum before being soldered together with the all-aluminum heat exchanger (1). The additional heat exchanger (4) is attached to the collecting reservoir (2) only via connecting sleeves (5) and soldered nuts (7).

Abstract: The aim is to make it easier to compare industrial or clinical processes. To this end provision is made for the processes to be systematically divided into prescribed process steps. The process steps are also divided into prescribed sub-process steps. Each of the processes is then shown in a respective graphic with the process steps in a first dimension and with the sub-process steps in a second dimension, so that each sub-process step has a distinct two-dimensional location in the respective graphic, with each sub-process step being graphically marked if the respective process contains it. The graphical presentation can now be used to compare the processes easily and clearly.

Abstract: A computer readable storage medium includes executable instructions to create a database structure that contains groups of linked data tables to store different types of metadata selected from Business Metadata, Structural Metadata and Operational Metadata. At least two different types of metadata are received. The database structure is populated with the at least two different types of metadata to form composite metadata.

Abstract: The aim is to simplify resource planning in a clinic or by a hearing aid technician. For this purpose, an audiometer and a method for operating an audiometer are proposed in which, following a simple hearing test, in addition to information as to whether treatment of a user with a hearing aid is necessary, the presence of any hearing-loss class in which the user can be grouped is also shown. In this way, the expense with regard to time, materials and personnel required for matching a hearing aid to a particular user can be more easily estimated.

Abstract: A heat exchanger, preferably an oil cooler (1) for a motor vehicle, comprises stacked flat tubes (2, 3, 4), which have tube ends with apertures for admitting and discharging oil, which flows through the flat tubes (2, 3, 4) in their longitudinal direction. The apertures of adjacent flat tubes (2, 3, 4) are in fluid communication with one another in order to form flow passages, and spacings are left between the flat tubes for a medium, in particular a cooling medium, to pass through. The flat tubes are designed as extruded multi-channel tubes.

Abstract: A fuel injection apparatus having at least one solenoid valve for controlling the fuel injection that is contained in a housing part and a solenoid assembly having a magnetic coil and a magnet armature inserted into a recess of the housing part. A cover piece that can be attached to the housing part fixes the solenoid assembly in the housing part. A spring element is disposed between the cover piece and the solenoid assembly and clamps the solenoid assembly in the housing part. At least one securing element is formed onto the spring element and is of one piece with it, which secures the spring element to the housing part and secures the solenoid assembly in the recess of the housing part without the cover piece being attached to the housing part.

Abstract: The invention related to a flat tube (1) comprising a return bend section (3), inside of which the flat tube (1) is bent back in such a manner that both planar tube sections (2a, 2b) thereof, which are connect to the return bend section, extend in a longitudinal direction with opposite flow-through directions (4a, 4b) and with longitudinal axes (5a, 5b) that are offset with regard to one another at least in the transverse direction (y). The invention provides that the return bend section (3) is formed in such a manner that a main bending axis (A) extends parallel to the flat tube to be plane and at a predeterminable angle to the tube longitudinal extension, whereby the flat tube plane is determined by the longitudinal and width extension of the flat tube (1).
