Title: Hearing aid with a high-gain, multistage transistor amplifier
Inventor: GAHLEITNER ERWIN
IPC: H04R25/00
Filed: 1981-04-04
Abstract: A hearing aid with a high-gain, multistage transistor amplifier is proposed whose gain is intended to be increased without producing acoustic feedback. An amplification stage (10) of the multistage transistor amplifier has an impedance network (18) serving as a collector resistance or emitter resistance. This network is dimensioned in such a way that the AC output voltage (UA), which is present between a tap (20) of the impedance network and a reference potential, is increased below a specific frequency (f1), in the frequency range which is important for good speech reproduction. No increase is intended to take place above this frequency. A reduction in the aforementioned frequency range can be provided if necessary. <IMAGE>

Patent DE-3204839-A1 (DE)
Title: Photodiode amplifier with a wide dynamic range
Inventor: PRASSE KARL-HEINZ DIPL ING
IPC: H04B10/69
Filed: 1982-02-11
Abstract: Fibre-optical links contain relay stations inserted at particular distances, in which the light signals are converted into electrical signals and are again amplified. Since the light power emitted by the fibre-optical link is comparatively very low and, in addition, can fluctuate within a certain range, a corresponding amplifier is proposed, the gain of which can be varied in dependence on an externally applied control voltage. The amplifier is built up of two amplifier stages, a drain-source path of a field-effect transistor being connected in parallel with the collector resistor of the first amplifier stage so that the effective collector impedance and thus the gain can be varied in dependence on the voltage applied to the gate terminal of the field-effect transistor. The invention is used, in particular, in the input amplifiers of fibre-optical links. <IMAGE>
Patent DE-3209056-A1 (DE)
Title: Supply container with a device for the extraction and simultaneous cut-off of web-shaped material wound on rolls
IPC: A47K10/32
Filed: 1982-03-12
Abstract: So that supply containers for rolled-up web-shaped material can be checked for stock and refilled without being dismounted, the rolls are stacked above one another and received and guided by means of their roll cores by a rod which passes centrally and vertically through the container and which is axially displaceable. The supply container is subdivided by a carrier plate respectively into a closable space for the particular accessible roll and for stock rolls, on the one hand, and for empty roll cores, on the other hand. The latter, when released by pulling a slide, fall through an exit orifice in the carrier plate into the lower part of the container. The upper door closing off the supply space possesses a viewing slit. The rod has a length corresponding to the height of the maximum stackable rolls and can be refilled after the release of its fastening to the housing cover and its fall down to the bottom of the lower container part which has the height of at least one roll width. A vertically extending tear-off strip is arranged on a rocker which is pivotable about a vertical pivot axis counter to spring force and which is equipped internally with a friction covering which, in the event of a sudden tear-off, retains the roll and, for example, allows a paper draw-off along a perforation line.
Patent DE-3212880-A1 (DE)
Title: Assembly device
Inventor: WEBER KARL-HEINZ
IPC: B23Q1/70
Filed: 1982-04-06
Abstract: The invention relates to an assembly device, in particular a screwing, riveting, indentation or thread-cutting device, which can be fastened to a stationary mounting and has an outer tube, in which at least a part of a drive motor as well as drive elements, guide devices, control elements and the like as well as a movable tool are accommodated, and a solid location strip to which the outer tube is secured and with which the assembly device can be secured to the mounting. Hitherto, the individual components were attached in the outer tube in the correct functional position before this outer tube was fastened to the holding strip by additional fastening elements. The outer tube and the holding strip were separately produced, expensive and heavy or rigid elements, since relatively high forces are to be transmitted from the outer tube to the holding strip. The object was to simplify an assembly device of the type mentioned at the beginning with regard to construction and assembly. This is achieved according to the invention in that the location strip together with the outer tube is designed as a one-piece portion of a light-alloy extruded section.

Title: Method for measuring the time between two analog electrical pulses, which can be repeated any number of times and has statistically distributed amplitudes
Inventor: HIPP JOHANN F DIPL PHYS
IPC: G04F10/00
Filed: 1982-05-03
Abstract: A method for measuring the time between two pulses which is characterised by the fact that two pulses each, the distance of which is to be measured, are converted into logical signals by means of a comparator and a logical signal of the difference between the beginning of the two pulses (the front edges) and a logical signal of the difference between the end of the two pulses (the back edges) is supplied in equal proportions to a start/stop counting device or measuring device and is there used for determining the time. This avoids amplitude-dependent measuring and enables an amplitude-independent measuring from time average to time average of the two pulses which can recur any number of times.

Title: Method for quality control in X-ray diagnosis
Inventor: BRONDER THOMAS DR RER NAT
IPC: H05G1/26
Filed: 1982-10-04
Abstract: The indirect electronic measurement of the time-dependent tube voltage of X-ray equipment is facilitated in the case of high and low tube currents, with great accuracy, by means of a small ray probe, in such a manner that a quotient signal, which is dependent on the tube voltage, is formed from two simultaneously occurring radiation detector signals, both radiation detectors using the radiation power which is available behind the radiation filter, which is necessary for both but is of uniform thickness, without further unnecessarily weakening additional filtering, in an optimum manner to generate the electrical signals. The spectral dependency of the two signals, which is necessarily different to form the quotient, is in this case produced by two radiation detectors being used which have very different spectral response characteristics. The quotient signal, which varies with the tube voltage, can be corrected by the systematic deviation of a measured calibration curve, by means of an electronic linearisation element, in order to increase the measurement accuracy. In addition, the peak value of the tube voltage at the time of the maximum dose power can be determined within a preset measurement time interval, prior to generation of the quotient signal, by means of two switchable peak value stores.
