Abstract: This hearing aid has no openings on the outside which are easily accessible to the user. For this purpose, the hearing aid housing (10) consisting of the housing bottom (11) and housing top (13) exhibits at the top a flattened area (14) through which an adjusting element (35) of a gain controller (32) protrudes. A rotary knob (50) is snapped onto the adjusting element, a small distance (h) to the sound inlet existing between the lower edge (55) of the rotary knob and the flattened area (14) in the snapped-on state. The flattened area contains a sound penetration opening (42) which is connected to a microphone (45) contained in the hearing aid housing. The flattened area furthermore contains openings (48, 49) for the free passage of adjusting elements (36) which belong to trimming resistors (33) and are covered by the rotary knob (50). <IMAGE>

Date Sep. 12, 1986.In order to obtain perfect scanning of audio and/or video disks through application of contactless scanning with a coarse and fine drive system for radial servo readjustment, the fine drive optimum working point is reached through a correct interaction of coarse and fine drive, even in the case of different large radial eccentricity amplitudes. This is achieved through adjustment of the coarse drive, using a comparator, as a threshold value detector, and through an evaluation of the pulse sequences occurring at the comparator output. A radial-error signal for the coarse drive is obtained from a control parameter for the fine drive. The coarse drive is started by pulses when the pulses obtained from a radial-error signal exceed a predetermined pulse-to-interval ratio.

Abstract: @ Excess currents due to faults in an electrical power system are generally larger than excess currents due to the magnetisation of distribution transformers: discrimination has hitherto relied on a threshold detector. Magnetising currents are however, asymmetrical whereas fault currents are symmetrical. This specification discloses a detector which can detect symmetrical current waveforms on a conductor 1 and thus discriminate between a fault and a magnetising excess current. A resistor 4, placed across the output terminals of a bridge rectifier 3 has a resistance selected so that the voltage across it exceeds the breakdown voltage of trigger diodes 7 and 8 when the current in conductor 1, in any half cycle, exceeds a desired maximum. Capacitors 13 and 14 will thus only both charge up in response to a large symmetrical current: a logic control 23 is connected via lines 21 and 22 to detect such a condition.

Abstract: A printing apparatus has an array of cartridges (40,41,42) for printing a web (2) of e.g. paper passing through the array, and one or more units (48,49) containing printing medium. The cartridges (40,41,42) each are capable of transferring the printing medium from the units(s) (48,49) to the web (2). The unit(s) (48,49) and the cartridges (40,41,42) of the array are relatively movable, to allow the unit(s) (48,49) to interact successively with at least two of the cartridges (40,41,42). In this way it is possible to change printing from one cartridge (40,41,42) to another, allowing changes to be made to what is printed, without halting the movement of web (2) significantly. The present invention also proposes that the cartridges (40,41,42) may have printing cylinders (43,44,45,46) of different sizes, and furthermore that a mobile unwind stand may be used to move web material to the printing apparatus, and the web output from the printing apparatus processed by sheet folding techniques.
