Abstract: A method is provided for producing a yarn from at least two individual yarn components having different physical characteristics so that the produced yarn has a desired visual effect. The method includes continuously supplying at least one yarn component in the form of a bundle of continuous filaments and individually treating the bundle of continuous filaments in a treating stage. The treated bundle of continuous filaments is then conveyed to a collective compacting stage. At least one other yarn component is supplied from a spinning beam or a bobbin directly to the collecting compacting stage and the bundle of continuous filaments and at least one other yarn component are compacted collectively in a collective compacting device.

Abstract: A hearing device has a microphone, a signal processor, an earphone and a number of externally accessible final control elements for setting audiological/acoustical parameters of the signal processor. An allocation stage is connected between the signal processor and the final control elements for allowing a number of combined and/or derived parameters to be simultaneously set by actuation of a single final control element.

Abstract: In the production of multicolored yarn from differently colored filament bundles, the individual bundles may be texturized collectively. Then they are separated again into crimped part-threads 11.3 through 11.5 and are compacted individually in after-compacting means 8 before these part-threads are jointly compacted in a collective compacting means 9 and subsequently are wound up as a yarn 12 in a winding device 10.

Abstract: For data exchange with a programmable hearing aid worn in the auditory canal, an electrical line is provided that contains leads in electrical contact with a circuit in the hearing aid and which is mechanically attached to the hearing aid so as to serve as an extractor for the hearing aid. The free end of the electrical line carries a signal receptor, such as a plug or socket or a wireless receiver with a gripping surface.

Abstract: A programmable hearing aid is provided with a programming socket. A space-saving arrangement of switch elements is provided wherein a switch element for switching the hearing aid on/off, an MTO switch, a volume control, a tone control, a situation switch or the like can be introduced into the programming socket that is free except during the programming event.

Abstract: In an arrangement to prevent the intrusion of foreign matter into a transducer which extends with a projection provided with an opening into a sound channel of a hearing aid, a reduced need for space as well as simpler construction, compared with the state of the art, are achieved by means of the following characterizing features: A membrane made of pore-free material is provided, which has at least one bore for the passage of sound of from a few hundredths to a few tenths of a millimeter diameter, and in which the wall thickness of the membrane is small with respect to the diameter of the bore.

Abstract: A hearing aid has a housing which includes electronic components such as a microphone, amplifier, power source and receiver, as well as suitable structure for mounting and retaining those components. The housing is inserted in a cavity in a shell. The exterior of the shell is matched to the shape of the auditory canal of the user. The cavity of the shell in which the housing is received tapers to a smallest diameter at a sound discharge end of the shell. The housing also has a smallest diameter at this location. A releasable latch is disposed in the region of the smallest diameter for holding said housing in place within the shell during use, but permitting removal of the housing for repair or replacement without damaging the shell.

Abstract: The thread retainer has a tube which is slotted from the side to form an access opening for a thread and a gate member in the form of a ball which is movably mounted in the tube. The ball cooperates with a second ball to define a thread passage with curvilinear walls. The movable ball may move under gravity or may be spring biased to permit entry of the thread into the thread passage.
